Introduction
Posttraumatic stress disorder (PTSD) is a serious and debilitating mental health
consequence following traumatic events that affects a substantial portion of the population (Breslau, Kessler, Chilcoat, Schultz, Davis, & Andreski, 1998; Kessler,
Sonnega, Bromet, & Nelson, 1995). Breslau and colleagues (1998) determined that as
much as 89.6 percent of the population has experienced some type of trauma (e.g. combat
exposure, assault, sexual assault); however, merely experiencing atraumatic event is not
sufficient to explain the development of PTSD (Ozer & Wiess, 2004). On average, seven percent of the population will go on to develop the disorder following a traumatic event
(Kessler et al., 1995). Understanding the reason why only a small percentage of those
exposed to traumatic events go on to develop PTSD long been a topic of debate among
researchers.
The perceived meaning of the traumatic event is an important aspect of the
response (Ehlers & Clark, 2000). Viktor Frankl highlighted the importance of meaning
following his experience as a Holocaust survivor in the Nazi concentration camps. In his book Man’s Search for Meaning (1959), Frankl described his own survival as dependent
upon his ability to find meaning to survive. He also noted that even the strongest prisoners appeared to die quickly if they lost a sense of purpose, such as finding out that
one’s family had been killed. Those who were not able to find a new source of meaning
1
2
were unable to adapt to the stress of the concentration camp. He coined the term “will to
meaning” to describe the continual process of finding meaning when what was once
meaningful is lost.
Meaning is a subjective phenomenon and is relative to each individual and may
change over time. The subjective nature of meaning makes it difficult to assess across populations (Reker & Fry, 2003). Despite its difficulties, the concept of meaning has begun to resurface in the research literature because of its continued significance in the
human response to traumatic events (Park & Ai, 2006). It has also been recently
reintegrated as an adjunct treatment to clinical interventions for PTSD (Southwick,
Gilmartin, McDonough, & Morrissey, 2006). In a sample of 9/11 terrorist attack
survivors, the ability to find meaning two months after the attack was associated with
reduced fear and posttraumatic stress symptoms (Updegraff, Silver, & Holman, 2008).
For the purposes of this research study, meaning will be defined in a manner
consistent with the conceptualization put forth by Steger and colleagues (2006) as those
aspects of life that give one a sense of purpose and provide an explanation for their own
existence. Frankl described one essential aspect for all humans is the will to meaning.
Every human being will strive to understand the world they live in and work to attain the
things that give their life value. As a Holocaust survivor, Frankl observed that individuals
that maintained a reason to live, had some meaning in life, survived better than those who
felt that life had lost all meaning. Thus, the concept of meaning in life is idiosyncratic to 3
each individual. The definition of meaning adopted should allow for individual
interpretation and establish a framework for the construct to be investigated.
Conceptualizations of Meaning
In order to have a sense of stability, humans generally prefer to think that the
world is organized in a certain order. This is the basis for Janoff Bulman’s theory of
shattered assumptions that affect the human adaptation to traumatic life experiences
(1992). Her premise is that in order for the world to be meaningful we make assumptions
about the way the world operates. There are three fundamental assumptions, with
subcategories, that inform us about what to expect from the world around us. Those
assumptions refer to the benevolence of the world, meaningfulness of the world, and
worthiness of the self (Janoff Bulman, 1989). The benevolence of the world is thought of
as a continuum where people will individually perceive the world as a generally good or bad place. Meaningfulness of the world is related essentially to justice. A meaningful
world is one where good things happen to good people and bad things happen to bad people. This assumption drives the negative cognition of “I’m a good person, this
shouldn’t be happening to me” often reported by trauma survivors. Good things also
should not happen to bad people according to this world assumption as well. The
worthiness of the self is the element that adjusts the individual’s perception of the world
and their place in it. A self perceived worthy person in a good world would expect to
4
have good things happen to them. A person that perceives themselves as not worthy in a
good world would not expect good things to happen for them. Traumatic events are
events that “shatter” those fundamental assumptions that gave our life meaning and the
upheaval potentially leads to PTSD.
Park and Folkman (1997) describe the concept of meaning in the human response
to stress in terms of an interaction between global meaning and situational meaning.
Global meaning encompasses the beliefs held by individuals that provide information
about how the world operates as well as the goals one has that provides a sense of purpose (Park & Folkman, 1997). Thus, global meaning is abstract and tenuously informs
one about general interactions with the environment. Situational meaning refers to the
specific interactions between an individual and the environment and is informed by the
higher order process of global meaning (Park & Folkman, 1997). The result of the two
interacting systems of meaning is that there is a wide spectrum of stressful events one can
encounter and not all of them require fundamental changes in global meaning. The process of searching for meaning is relegated to stressful events that are unable to be
resolved within situational meaning.
Measuring Meaning
The importance for individuals to develop meaning following a traumatic event
continues to be regarded as an integral but difficult to measure phenomenon
5
(Chamberlain & Zika, 1988; Park & Folkman, 1997; Park & Ai, 2006; Steger, Frazier,
Oishi, & Kaler, 2006). The idiosyncratic nature of meaning serves to make measuring the phenomenon more difficult (Steger et al., 2006). Various methods have been developed
to measure meaning but often are qualitative and difficult to replicate or are confounded by unclear construct validity (Steger et al., 2006). In addition, there is a strong need for
valid measures of meaning making that can be used in longitudinal research (Park & Ai,
2006).
One recent measure developed to assess meaning is the Meaning in Life
Questionaire (MLQ; Steger et al., 2006). This measure has two five item scales
measuring searching for meaning and presence of meaning respectfully. Research
indicates that searching for and finding meaning early following stressful events is
associated with less subsequent distress (Davis et al., 1998; Updegraff et al., 2008) but searching for meaning does not always result in finding meaning (Updegraff et al., 2008).
Further, not everybody that experiences a stressful or traumatic event will need to find
meaning to foster adaptation to the stressor (Davis, Wortman, Lehman, & Silver, 2000;
Folkman, 1984; Park & Ai, 2006; Park & Folkman, 1997). The essential element missing
in the meaning making literature is the mechanism that facilitates the ability to find
meaning for those who are searching. The development of the MSE measure is an
attempt to identify a possible mechanism that can be quantitatively examined that may bridge the gap between searching for and finding meaning following traumatic events.

Posttraumatic Growth
The posttraumatic growth literature has been influential in understanding the
complexity of the human response to trauma (Park & Ai, 2006). Posttraumatic growth is based on the logic that traumatic events may cause individuals to re evaluate the
importance of things in life and that the re evaluation has the potential to lead to perceived benefits or growth (Tedeschi & Calhoun, 1996, 2004). Tedeschi and Calhoun
(1996) developed the posttraumatic growth inventory (PTGI) to assess the degree of
change experienced by trauma survivors in several domains: a) perceived changes in self; b) changed sense of relationship with others; c) changed philosophy in life. Posttraumatic
growth has been suggested as a possible target for clinical interventions that focus on
strengths rather than on vulnerabilities (Tedeschi & Kilmer, 2005).
The concept of posttraumatic change is very similar to the concept described as positive construal elsewhere in the literature (Davis, Nolen Hoeksema, & Larson, 1998).
The changes that occur in one’s life in these domains of posttraumatic growth are posited
to reflect positive outcomes but that view has come under scrutiny recently (Sumalla,
Ochoa, & Blanco, 2009). Hobfoll and colleagues (2007) found that posttraumatic growth
was related to greater psychological distress, retaliatory endorsement by Israeli trauma
survivors, and more extreme political views. Closer inspection of the items of the PTGI
reveals that changes in one’s orientation to more extreme views and perceived by the
7
individual as positive can result in this observation. It is not clear that posttraumatic
growth is necessarily a clear indicator of successful adaptation to traumatic events
(Maercker & Zoellner, 2004; Tedeschi & Kilmer, 2005). The association between posttraumatic growth and generating meaning in the context of posttraumatic sequelae is
not entirely clear a priori . It is possible that the search for, or acquisition of, meaning is
reflected in the posttraumatic growth outcomes.
The previous conceptualizations of meaning have been beneficial but appear to be
somewhat distinct from Frankl’s will to meaning. The will to meaning appears to be a
description of a proactive approach more like a coping process than a single act (Park &
Folkman, 1997). The process requires the ability to recall information that was important
to the individual prior to the traumatic event, evaluate what has changed following (or
during in some situations) the traumatic event, and integrating that information to make a
decision about what is important to the individual at that time. Thus, generating meaning
is a task without a clearly defined goal to reach and is subject to change throughout the process (Park & Folkman, 1997). This process is heavily invested in self regulatory behaviors that are ideal targets for modification (Bandura, 1997).
This dynamic process can be investigated using social cognitive theory. Bandura
(1997) developed social cognitive theory to explain and predict a wide range of human behavior. In addition, the self efficacy mechanisms through which social cognitive theory
has established its utility are malleable, and therefore may be targeted for intervention
8
following traumatic events (Benight & Bandura, 2004). The theoretical framework of
social cognitive theory may also serve as a means to investigate the importance of
meaning following a traumatic event without the difficulty of establishing an exact
definition of what meaning is relative to each individual. Investigating the perceived
ability of trauma survivors to generate meaning may accomplish this goal. The purpose of
this study is therefore to develop a measure that assesses the perceived ability of trauma
survivors to generate meaning following a traumatic event. The theoretical framework
underlying the development of the meaning self efficacy scale (MSE) is described below.
Social Cognitive Theory
Social cognitive theory was developed with the fundamental observation that
humans are highly adaptable to their environments because of our ability to use self
regulation and forethought to plan our behavior (Bandura, 1997). Humans have the
capacity to think using abstract symbols to plan and guide behavior that is intended to bring about desirable results (Bandura, 1977). Thus, humans are agents able to interact
with their environments and our behaviors are the result of planned actions. The
experience from those actions is integrated into the planning of future actions. This
dynamic system is called triadic reciprocal determinism and consists of three primary
factors that influence each other as bidirectional determinants of human behavior: person
factors (cognitive, affective, and biological), behavior, and the environment (Bandura,
9
1986, 1997). These factors vary in the degree to which they influence each other. At a
given time, any one factor may be a stronger, or weaker, influence on individual behavior
in response to the different demands that may be present. For example, someone that is
trying to quit drinking would have very little environmental demands to abstain from
alcohol use if there were none available. On the other hand, if alcohol was readily
available (environmental), then the strength of the environmental influence and behavioral factors (i.e. past drinking) to abstain from drinking for the individual would be
much greater. The previous example also highlights the role of human agency in self
regulative behavior. The Social Cognitive framework places humans as active agents in
the shaping of their environments and not limited to reacting to the situations in which
they find themselves (Bandura, 1986, 1989, 1997, 2001). As an agent shaping the
environment, the individual trying to quit drinking can choose to avoid environments that
may promote alcohol consumption (i.e. bars, night clubs) if they believe that they would be influenced to drink. The strength of the influence to drink or not involves the
individual’s perceived self efficacy beliefs in their ability to abstain or not in an
environment where alcohol is available.
Self efficacy beliefs are at the core of social cognitive theory. Perceived self
efficacy is one’s belief in their ability to use their skills and knowledge to bring about
desired results (Bandura, 1997). Self efficacy beliefs appear on the surface to be similar
to outcome expectancy but they are quite distinct from one another. Outcome expectancy
10
is the notion that a given action will result in a particular outcome, whereas self efficacy beliefs involve the individual’s belief in their ability to act in a manner to reach a desired
outcome. The predictive ability of self efficacy beliefs are considerably greater than those
of outcome expectancy (Bandura, 1997). The strength of the self efficacy belief directly
influences the likelihood and the type of action that will be performed as well as the
amount of effort put into it. If people believe they are not capable of performing an action
they are not likely to attempt it or will put forth very little effort into performing it well.
Self efficacy beliefs arise from four main sources: mastery experiences, vicarious
experience, verbal persuasion, and physiological states (Bandura, 1977, 1986, 1997).
Mastery experiences are the most powerful source of self efficacy beliefs because
they provide specific feedback to the individual for the behavior that has been performed
(Bandura, 1977, 1997). Successful mastery of specific task will raise self efficacy beliefs
and sustained failures will reduce them (Bandura, 1977). The best way for someone to
know if they are capable of performing a task is the direct information that is gained from
attempting the task. Failures, especially if they are constant, should reduce the person’s belief in their ability to perform the task. It is important to note that the perception of the
success or failure is relevant to the effect that success or failure has on efficacy beliefs
(Bandura, 1977, 1997). Successful completion of a task will increase efficacy if the person perceives the success as a result of their own capability and not some external
factor. To further stress the importance of the cognitive realm in Social Cognitive theory,
11
sometimes successful completion of a task can undermine self efficacy (Bandura, 1977).
Success that comes from a result of laborious effort may result in the perception of
having little aptitude for the performance of the given task.
Vicarious experiences are another important source of self efficacy information.
There would not be enough time for every person to gain mastery experiences of every
human endeavor. By observing others successfully performing a task, or react to a
threatening situation (systematic desensitization), then the individual gain symbolically
formulated expectations for their own performance on a given task (Bandura, 1977;
Maddux, 1995). Merely seeing a model perform a task or demonstrate a particular
reaction is not sufficient to produce changes in the perception of self efficacy beliefs.
Models that are similar to the individual viewing them will have a greater effect than
models that are different from them (Kazdin, 1974; Meichenbaum, 1971). Modeling behaviors can be accomplished cognitively by imagining the modeled behavior (Kazdin,
1974) but the effect of imagined, or “covert” modeling will not be as informative as viewing a directly observed model (Bandura, 1977). As noted before, the effect of vicarious experience is not as strong as mastery experiences, but at times that mastery experiences are not practical (i.e. war, natural disaster, or other traumatic scenarios) the availability of similar models may be useful to promote adaptation.
The third source of efficacy information is derived from verbal persuasion. Verbal persuasion has an overall weaker effect than other sources of efficacy, but if the
12
persuasion seems realistically achievable, it can have some effect (Bandura, 1977, 1997).
The characteristics of the person offering the verbal persuasion are very important for it
to have any effect on self efficacy beliefs (Bandura, 1977, 1997; Maddux, 1995).
Someone offering support that appears to have no credibility has very little to no effect
on self efficacy beliefs. Conversely, if the source of the support appears to be credible, an
expert, or the source is preferred, then it can increase the amount of effort that is put forth
and sustained (Maddux, 1995). To have the greatest effect on self efficacy beliefs, performance feedback should be structured to provide the person with realistic feedback
on obtaining goals that are only minimally outside of their current capabilities (Bandura,
1997).
Physiological states provide the final source of self efficacy information.
Emotional arousal in certain situations or activities can be a useful source of information
relating to capabilities for a specific situation (Bandura, 1977). A good example may be a person who is physiologically aroused from fear of heights. That arousal could be an
indicator to prevent that individual from working on skyscrapers. As Schachter and
Singer (1962) demonstrated, the arousal alone is not the sole determinant of the human
response to physiological responses, but how that arousal is attributed and interpreted is
much more important. The perception of our arousal is integrated into the self regulatory
system and provides valuable information that allows the individual to make decisions
about their abilities and plan goals accordingly (Bandura, 1991, 1997).
13
Self efficacy beliefs come from the four sources mentioned but to fully understand their predictive utility it is important that they are interpreted as appropriate given their magnitude, generality, and strength (Bandura, 1977, 1986, 1997; Maddux,
1995). Magnitude refers to the levels of functioning that the self efficacy beliefs related to the level of difficulty inherent in the task. It may range from high self efficacy in easy levels of difficulty to low self efficacy in more difficult levels of performance. The generality of a self efficacy belief can range from the specific situation, or it may extend to other areas of functioning. For example, belief in the ability to ride a bicycle may extend to motorcycles, all terrain vehicles, or other basic riding skills. The strength of the self efficacy belief is also very important to consider. Weak beliefs can be reduced easily, and strong beliefs may persist after continuous performance failures.
Social Cognitive Theory of Traumatic Recovery
The experience of a traumatic event can be understood as encountering an event or situation that exceeds one’s abilities to control or meet the demands of the situation.
Helplessness is one of the main diagnostic criteria for the reaction to a traumatic event
(American Psychiatric Association [APA], 2000) and can result from the perception that an individual is not able to exert influence over their environment (Abromsom, Seligman,
& Teasdale, 1978). Given the unpredictable nature of traumatic events, exerting control over the situation is likely impossible. If it were possible, then people would avoid the
14
situation altogether. Social cognitive theory states that the individual’s perceived ability
to exert some control over the situation (e.g., cognitive rather than physical) will be more predictive of their reaction and adaptation to the event than the actual outcome (Benight
& Bandura, 2004). Reviewing the theories and literature surrounding the human
adaptation to traumatic stress, Benight and Bandura (2004) determined that coping self
efficacy (CSE, the perceived ability to meet the demands of posttraumatic recovery) is a
significant mediator of posttraumatic distress. CSE has been found to be an important
variable in understanding and predicting posttraumatic reactions (Benight & Bandura,
2004; Benight, Freyaldenhoven, Hughes, Ruiz, Zaschke, & Lovallo, 2000; Benight &
Harper, 2002; Benight et al., 1999; Benight, Swift, Sanger, Smith, & Zeppelin, 1999).
MSE Scale Development
The MSE scale was developed to assess the perceived ability to generate meaning
following a traumatic event. Bandura (2006) provided a guide to develop self efficacy
scales. The recommendations include using a Likert type scale with a range of values between 0 and 10, and formulating items specific to the construct intended to measure.
Existing scales were examined to gain an understanding about the content that should be
included and what already exists. An unpublished measure of general coping self efficacy
(CSE), the Assumptive Worlds scale (Janoff Bulman, 1989), and a measure of
meaningless (unknown title and author) were examined to formulate MSE item content.
15
The items generated for the MSE scale use language that implies the performance of a behavior (i.e. generate meaning in my life…) and are scored on an 11 point Likert type
scale ranging from 0 “not at all able” to 10 “highly able.” The items were worded directly
to investigate the construct of generating meaning (Bandura, 1992; 2006). An initial item pool of 19 items was generated by the author to investigate the construct of MSE.
Participants were prompted to rate his or her perceived ability to engage in the behavior
of each item “as of right now.”
Current Investigation
This investigation describes several studies conducted in the development and validation of the MSE scale. Study 1 describes the item pool selection and principal components analysis of the MSE as well as the convergent and criterion validity of the measure. If the MSE construct is valid, then it should be positively associated CSE and negatively associated with posttraumatic distress. The measure should not be significantly associated with social desirability. Study 2 describes the maximum likelihood investigation of the factor structure for the reduced MSE scale resulting from the principal components analysis of Study 1. The reduced form of the measure should continue to be positively associated with adaptive measures and negatively associated with measures of distress and anxiety. An additional hypothesis investigated in Study 2 is that the MSE will predict unique variance in posttraumatic distress after controlling for social support. Study 3 investigates the temporal stability of the MSE over a two week timeframe.

Method
Participants
Data was collected from 277 undergraduate students that participated in the study to gain extra credit for psychology courses. The sample was mostly female (83%) and
Caucasian (79.1%). Further demographic information for the population is provided in
Table 1. A total of 19 participants reported not experiencing a trauma. Data analysis did not differ with the no trauma participants excluded and were therefore not excluded from the final analysis.
Measures
Demographics. A 9 item demographics questionnaire was included in the study to gather information about participants’ age, ethnicity, gender, marital status, employment, education, income, home status (i.e. rent, own), and religious preference. See table 1 for details.
Posttraumatic Stress Disorder Checklist (PCL) . The Posttraumatic Stress
Disorder Checklist (Weathers, Litz, Herman, Huska, & Keane, 1994) is a 17 item self report measure assessing 17 core symptoms of PTSD as specified by DSM IV (APA,
1994). The PCL asks participants to rate how much they were bothered by each PTSD

symptom in the past month on a 1 5 point Likert type scale in which 1 indicates “not at all” and 5 indicates “extremely”. In the current sample, the scale reported a high level of internal consistency with a Cronbach’s alpha of .92.
Marlowe Crowne Social Desirability Scale (MCSDS). The MCSDS (Crowne &
Marlowe, 1960) is a 33 item self report measure that was developed to measure the social desirability of individuals that are not undergoing assessment for psychopathology.
Participants respond true or false to items that may indicate presentation of oneself in a more favorable manner. In the current sample, the scale reported an adequate level of internal consistency with a Cronbach’s alpha of .76.
Coping Self Efficacy (CSE). The CSE is a measure designed by Dr. Charles
Benight at the University of Colorado at Colorado Springs to assess the self reported competency of meeting the demands of coping following a traumatic event. The scale consists of 20 questions and utilizes a seven point Likert type scale anchored with 1 indicating “not at all capable” and 7 indicating “I’m totally capable.” This measure was included in the study to provide information related to convergent validity. Both measures were developed using the same theoretical framework but intended for dissimilar constructs. In the current sample, the measure reported a high level of internal consistency with a Cronbach’s alpha rating of .96.
Procedure
23
This study was approved by the Institutional Review Board (IRB) and all participants signed informed consent prior to participating in the research. Participants
signed up to participate in the study using an online research program sponsored by the
university. Participants were invited to participate in the study if they had experienced a psychological trauma during their lifetime. The criterion A 1 for the DSM IV TR PTSD
diagnosis (experiencing or witnessing an event that threatened death or physical harm to
the individual or another) was given to participants to clarify what is defined as a
traumatic event(American Psychiatric Association [DSM IV TR], 2000). Participants
then responded to an online survey and were awarded extra credit for their psychology
courses when they exited the survey. Participants were not required to complete the
survey to receive credit. Exiting the system before completing the survey deleted the participant’s responses and the data was therefore not used in the analysis.
Data Analysis
Pearson product moment correlations were examined to determine the performance of the MSE scale to the related CSE measure, social desirability, and posttraumatic distress. The initial 19 items of the MSE was submitted to principal
components analysis with varimax rotation to identify the items of the measure that were
accounting for the most variance (Fabrigar, Wegener, MacCallum, & Stahan, 1999;
Floyd & Widaman, 1995). Component loadings greater than .40 are considered
significant (Field, 2009). Components were analyzed based on Eigen values greater than
24
one and an analysis of the scree plot. Item retention was determined based on the amount of variance accounted for by component loadings as well as the theoretical relevance to the construct of meaning self efficacy. Cronbach’s alpha was examined for the MSE scale to investigate inter correlations among the items as a measure of internal consistency.
Results
All analyses investigating the psychometric properties of the MSE were conducted using the statistical package for social sciences (SPSS, v15). The means, standard deviations, and Pearson correlations for the variables investigated are presented in Table 2 below. Participants in the study reported a low level of posttraumatic distress
(M = 39.16, SD = 13.44) falling well below the recommended cutoff score of 51 on the
PCL (Ruggiero, Ben, Scotti, & Rabalais, 2003). The 19 items of the MSE reported a
Cronbach’s alpha of .89 indicating good internal consistency. Pearson correlations indicate that the MSE performed in a manner consistent with the theoretical development of the measure. The MSE was significantly positively correlated to the CSE measure indicating convergent validity. Importantly, the correlation coefficient between the MSE and the CSE was strong ( r = .67, p < .01) but low enough to indicate that the MSE is measuring something unique from the CSE measure. Participants reported high levels of meaning self efficacy ( M = 123.08, SD = 28.73) and coping self efficacy ( M = 103.83,

SD = 22.7). This result is consistent with the theory of the MSE scale’s development and the literature supporting CSE (Benight & Bandura, 2004; Benight & Harper, 2002).
Principal components analysis with orthogonal rotation indicated four components with
Eigen values greater than one accounting for 61.3% of the variance: Generating Meaning,
Perceived Meaning, Religion/Control, and Just World. Component loadings for the items are reported in Table 3. The Generating Meaning component accounted for 38.4% of the variance with 11 items reporting significant loadings: the Perceived Meaning component accounted for 9.5% of the variance and had 3 items with significant loadings; the
Religion/Control component accounted for 7.5% of the variance with 2 items loading significantly on it; the Just World component accounted for 5.8% of the variance and had
4 items with significant loadings.

Discussion
The MSE scale demonstrated a significant negative relationship with posttraumatic distress providing initial evidence of criterion validity. The measure also demonstrated initial evidence of convergent validity with CSE. The PCA of the measure indicated four components that accounted for the majority of the variance in the MSE.
However, analysis of the scree plot indicates that the performance of the measure is best accounted for as one single component. In addition, three items loaded significantly on more than one component. Inspection of the items indicated that some items should be removed from the measure for several reasons. First, some of the items contained double statements making responses more difficult to respond to and interpret (Clark & Watson,
1995). For example, the item “Control thoughts about life being futile and absurd” may be confusing to answer because the respondent is asked about their perceived ability to control thoughts as well as respond to life being futile and absurd. The Religion/Control factor also appears to add little to the performance of the measure. Of the two items loading significantly on the component, one item is awkwardly phrased making it potentially open to distorted responses by individuals with lower reading levels (Clark &
Watson, 1995). There are already several good measures of religious coping in the literature so it was determined that the component could be eliminated from the measure
31
32
(see Ano & Vasconcelles, 2005). A total of 9 items of the MSE were retained for further analysis in Study 2.
Study 2
The primary goals of this study were to examine the convergent, discriminant, and criterion validity of the reduced 9 item MSE instrument. An additional goal of this study was to examine factor structure of the reduced measure in a sample of undergraduate students.
33
Method
Participants
Data was collected on 318 undergraduate students that participated in the study to gain extra credit for psychology courses. Of the overall sample, 27 participants appeared to not respond to the question content and were excluded from the final analyses.
Participants were determined to be non responders by invariable responses on more than one measure in the study (e.g. either maximum or minimum scores). The resulting sample consisted of 291 participants with valid data. The remaining sample was mostly female (51.9%) and Caucasian (83.8%). Further demographic information for the population is provided in Table 4.
Measures
Demographics. A 9 item demographics questionnaire was included in the study to gather information about participants’ age, ethnicity, gender, marital status, employment, education, income, home status (i.e. rent, own), and religious preferences.
Traumatic Stress Schedule (TSS). The TSS is a self report measure that assesses ten different categories of traumatic experiences including a non specific question. The measure consists of both open and closed ended questions scored on a 6 point Likert type

scale to assess the severity and impact of traumatic events. The most common trauma reported in the current sample was the death of close friend or family to accident, suicide, or murder (51.5%), followed by assault (34.7%), and seeing someone seriously injured or killed (32.6%). The majority of participants reported experiencing more than one type of trauma (69.1%).
Meaning Self Efficacy (MSE). The MSE used in this analysis was the reduced 9 item measure resulting from the previous analysis. The scale reported a high internal consistency coefficient with a Cronbach’s alpha ratings of .89, 87, and 86 for the full scale, Generating Meaning, and Perceived Meaning sub scales respectively. The high inter correlations among the items are quite high considering the small number of items that are included in the scale. This indicated that the measure performed as well with the reduced number of items focused more closely on the construct of generating meaning.
Coping Self Efficacy (CSE). The CSE is a measure designed by Dr. Charles
Benight to assess the self reported competency of meeting the demands of coping following a traumatic event. The scale consists of 20 questions and utilizes a seven point
Likert type scale with 1 (not at all capable) and 7 (I’m totally capable). This measure was included in the study to provide information about convergent validity. Both measures were developed using the same theoretical framework but intended for slightly dissimilar constructs. In the current sample, the measure reported a high level of internal consistency with a Cronbach’s alpha rating of .95.
39
Posttraumatic Stress Disorder Checklist (PCL) . The Posttraumatic Stress
Disorder Checklist (Weathers, Litz, Herman, Huska, & Keane, 1994) is a 17 item self report measure assessing 17 core symptoms of PTSD as specified by DSM IV (APA,
1994). The PCL asks participants to rate how much they were bothered by each PTSD symptom in the past month on a 1 5 point Likert type scale in which 1 indicates “not at all” and 5 indicates “extremely”. In the current sample, the scale reported a high level of internal consistency with a Cronbach’s alpha of .91.
Marlowe Crowne Social Desirability Scale (MCSDS). The MCSDS (Crowne &
Marlowe, 1960) is a 33 item self report measure that was developed to measure the social desirability of individuals that are not undergoing assessment for psychopathology.
Participants respond true or false to items that may indicate presentation of oneself in a more favorable manner. In the current sample, the scale reported an adequate level of internal consistency with a Cronbach’s alpha of .72.
Stait Trait Anxiety Inventory (Form Y) (STAI). The STAI (Spielberger, Gorsuch,
Lushene, Vagg, & Jacobs, 1983) is a 40 item self report measure that assesses state and trait characteristics of anxiety. The current study used the 20 item scale reflecting state anxiety. This measure was included to examine the relationship between trait anxiety and its relationship to MSE. This scale reported a high level of internal consistency with a
Cronbach’s alpha of .89.
40
Social Support. Social support (SOC) was analyzed in the study using a six item self report measure of the perceived emotional availability of emotional and tangible support. The measure uses a 1 5 point Likert type scale with items scaled to reflect the how often the support indicated is available. Items are coded to range from 1 “None of the time” to 5 “All of the time.” Social support is an important predictor of the development of PTSD (Ozer, Best, Lipsey, & Weiss, 2003; Ozer & Weiss, 2004). In the current sample, the scale reported a high level of internal consistency with a Cronbach’s alpha of .90.
Posttraumatic Growth Inventory (PTGI). The PTGI (Tedeschi & Calhoun, 1996) is a 21 item self report measure designed to investigate the positive aspects of post trauma events. The measure is intended to estimate the positive change experienced by trauma survivors in several domains: new possibilities, relating to others, personal strength, spiritual change, and appreciation of life. The PTGI reported a high level of internal consistency in the sample with a Cronbach’s alpha of .95.
Procedure
This study was approved by the IRB and all participants signed informed consent prior to participating in the research. Participants signed up to participate in the study using an online research program sponsored by the university. Participants were invited to participate in the study if they had experienced a psychological trauma during their lifetime. The criterion A 1 for the DSM IV TR PTSD diagnosis (experiencing or
41
witnessing an event that threatened death or physical harm to the individual or another)
was given to participants to clarify what is defined as a traumatic event(American
Psychiatric Association [DSM IV TR], 2000). Participants then responded to an online
survey and were awarded extra credit for their psychology courses when they exited the
survey. Participants were not required to complete the survey to receive credit. Exiting
the system before completing the survey deleted the participant’s responses and the data
was therefore not used in the analysis.
Data Analysis
Pearson product moment correlations were examined to determine the performance of the reduced MSE scale to the related CSE measure, social desirability, posttraumatic distress, posttraumatic growth, and anxiety. The reduced 9 items of the
MSE were then submitted to exploratory factor analysis with maximum likelihood
estimation and promax rotation. This method of analysis was used to investigate the performance of the items of the measure while not assuming factor orthogonality
(Fabrigar, Wegener, MacCallum, & Stahan, 1999; Floyd & Widaman, 1995). Factor
loadings greater than .40 are considered significant. Factors were analyzed based on a
combination of factors with Eigen values greater than one and an analysis of the scree plot. Cronbach’s alpha was examined for the MSE scale to investigate inter correlations
among the items as a measure of internal consistency. Hierarchical multiple linear
regression was utilized to investigate the strength of the relationship between MSE and
42
posttraumatic distress. Social support was included in the first block of the model to
investigate whether or not the MSE scale is accounting for a unique portion of the
variance in the outcome measure after controlling for social support.
Results
All analyses of the MSE were conducted using the statistical package for social sciences (SPSS, v18). The means, standard deviations, and Pearson correlations for the variables investigated are presented in Table 5. Participants in the current sample reported posttraumatic distress levels below the recommended cutoff values for the PCL
(Ruggiero et al., 2003). Pearson correlations indicate that the MSE continued to perform in a manner consistent with the theoretical development of the measure with the reduced number of items. The MSE was significantly positively correlated to the CSE measure maintaining convergent validity in the current sample. Exploratory factor analysis with oblique rotation and analysis of the scree plot indicated two factors with Eigen values greater than one that accounted for a total of 68.7% of the variance (see table 6). The first factor reflects Generating Meaning with 6 items reporting significant factor loadings.
Example items from this scale include “Find a greater sense of purpose in my life” and
“Generate meaning in my life after my trauma.” The second factor reflects Perceived
Meaning with 3 items reporting significant factor loadings. An example item from this scale is “Look at my trauma in such a way as to find meaning in the event.” The MSE

Discussion
The analysis of the reduced 9 item MSE measure indicated that the measure is best accounted for by two factors: Generating Meaning and Perceived Meaning. The
internal consistency for the total score for the measure and the subscales were good. The
MSE demonstrated convergent validity with CSE and discriminant validity with social
desirability. The MSE was significantly and negatively correlated with posttraumatic
distress in this sample providing evidence of criterion validity. However, the magnitude
of the relationship with posttraumatic distress was not as strong as it was with the larger
measure. In addition, the MSE did not account for unique variance in posttraumatic
distress in after controlling for social support.

Method
Participants
Data was collected on 73 undergraduate students that participated in the study to gain extra credit for psychology courses. Of the overall sample, 43 (59%) participants provided data for both time points test retest reliability of the MSE and were included in the analyses. The remaining sample was mostly female (87.3%) and Caucasian (81.4%).
The average time between completing questionnaires was 16.5 (SD = 2.7) days. The

(34.9%), and seeing someone seriously injured or killed (27.9%) and 48.7 percent
experiencing more than one type of trauma.
Meaning Self Efficacy (MSE). The MSE used in this analysis is the reduced 9 item
measure described previously. The scale reported a high internal consistency coefficient
with a Cronbach’s alpha rating of .92, .92, and .78 for time 1 full scale, Generating
Meaning, and Perceived Meaning subscales, and .89, .91, .89 for time 2 full scale,
Generating Meaning, and Perceived Meaning subscales respectively.
Coping Self Efficacy (CSE). The CSE is a measure designed by Dr. Charles
Benight to assess the self reported competency of meeting the demands of coping
following a traumatic event. The scale consists of 20 questions and utilizes a seven point
Likert type scale with 1 (not at all capable) and 7 (I’m totally capable). In the current
sample, the measure reported a high level of internal consistency with a Cronbach’s alpha
rating of .96 for time 1 and .97 for time 2.
Posttraumatic Stress Disorder Checklist Civilian Version (PCL) . The
Posttraumatic Stress Disorder Checklist (Weathers, Litz, Herman, Huska, & Keane,
1994) is a 17 item self report measure assessing 17 core symptoms of PTSD as specified by DSM IV (APA, 1994). The PCL asks participants to rate how much they were bothered by each PTSD symptom in the past month on a 1 5 point Likert type scale in
which 1 indicates “not at all” and 5 indicates “extremely”. In the current sample, the scale
56
reported a high level of internal consistency with a Cronbach’s alpha of .94 for time 1
and .97 for time 2.
Stait Trait Anxiety Inventory (Form Y) (STAI). The STAI (Spielberger, Gorsuch,
Lushene, Vagg, & Jacobs, 1983) is a 40 item self report measure that assesses state and
trait characteristics of anxiety. The current study used the 20 item scale reflecting state
anxiety. This scale reported a high level of internal consistency with a Cronbach’s alpha
of .93 for both time 1 and time 2.
Social Support. Social support (SOC) was analyzed in the study using a six item self report measure of the perceived emotional availability of emotional and tangible support. The measure uses a 1 5 point Likert type scale with items scaled to reflect the how often the support indicated is available. Items are coded to range from 1 “None of the time” to 5 “All of the time.” In the current sample, the scale reported a high level of internal consistency with a Cronbach’s alpha of .84 for time 1 and .86 for time 2.
Procedure
This study was approved by the IRB and all participants signed informed consent prior to participating in the research. Participants signed up to participate in a two part study using an online research program sponsored by the university. Participants were invited to participate in the study if they had experienced a psychological trauma during their lifetime. The criterion A 1 for the DSM IV TR PTSD diagnosis (experiencing or witnessing an event that threatened death or physical harm to the individual or another)
57
was given to participants to clarify what is defined as a traumatic event(American
Psychiatric Association [DSM IV TR], 2000). Participants then responded to an online survey and were awarded extra credit for their psychology courses when they exited the survey. Two weeks later, the participants were sent an email with a password to log in to the second part of the study to complete the second survey. Participants were not required to complete the surveys to receive credit. Participants that did not complete the first survey were not sent an email to participate in the second iteration of the study. Exiting the system before completing the survey deleted the participant’s responses and the data was therefore not used in the analysis.
Data Analysis
Pearson product moment correlations were calculated to investigate the relationship between the MSE, CSE, STAI, SOC, and the PCL variables over a two week interval.
Results
All analyses of the MSE were conducted using the statistical package for social sciences (SPSS, v18). The means, standard deviations, and Pearson test retest correlation coefficients for the variables investigated are presented in Table 9. Similar to Studies 1 and 2, participants reported a low level of posttraumatic distress symptoms. The temporal stability of the two subscales was investigated as well and they were determined to be modestly correlated. The test retest correlation coefficients for the Generating Meaning and Perceived Meaning subscales were .58 and .50 respectively.

Higher scores on the MSE and CSE scales represent adaptive self efficacy; higher scores on the SOC reflect more perceived social support available; higher scores on the PCL reflect greater posttraumatic distress; higher scores on the STAI reflect greater state anxiety.
Discussion
The test retest reliability for the MSE instrument was modest over a two week
interval. It is possible that the low reliability of the measure may reflect the low distress
of the sample. The participants may not have responded to the measure consistently because they have not experienced traumatic events that cause significant enough distress to prompt a need for generating meaning. It is also possible that some of the participants responded differently to the measure on the second assessment because of reflecting on the impact of the traumatic experience.
60
General Discussion
This study investigated the reliability and validity of a new self report measure to assess the perceived ability to generate meaning in survivors of traumatic life events. The initial pool of 19 items was generated to reflect the theoretical construct of generating meaning after trauma. Through the process of empirically examining the items and theoretical considerations, a reduced 9 item measure was produced that reflects the MSE construct. This measure can be used as a single overall measure of MSE although two subscales were identified for the instrument as well: Generating Meaning and Perceived
Meaning. Internal consistencies for the full scale measure as well as the subscales indicated were good but the test retest reliabilities were modest. The construct validity of the MSE was supported by the strong relationship with the CSE measure. The MSE and subscales were also associated negatively with posttraumatic distress symptoms and anxiety. However, the correlation coefficients with posttraumatic distress were significant but weak. The MSE was not significantly correlated with social desirability, age, ethnicity, income, or education.
The MSE was significantly and positively associated with posttraumatic growth in the current investigation. However, unlike the MSE, posttraumatic growth was associated
61
62
with greater posttraumatic distress. The reason for the differential performance of the
instruments is not self evident but it may reflect the inconsistent association of posttraumatic growth and psychological outcomes (Maercker & Zoellner, 2004; Tedeschi
& Kilmer, 2005). Further investigation of both constructs in a clinical setting may be
useful to determine whether the observed differences are maintained.
The relationship between MSE and posttraumatic distress was significant and
associated in the conceptually derived direction but with only a weak correlation.
However, the MSE demonstrated a strong positive correlation with CSE in each of the
administrations and the CSE had stronger relationship with posttraumatic distress. That
leads to the question that if the two measures have a strong positive relationship, why is
there such a difference in the amount of posttraumatic distress variance accounted by the
two measures? One possible explanation for this is that the sample reports experiencing
overall low levels of posttraumatic distress. The majority of participants in each sample
did not report posttraumatic distress symptoms to a degree that suggests possible PTSD
(Rugiero, et al., 2003). In addition, CSE has been shown to mediate posttraumatic distress
following natural disasters (Benight & Harper, 2002) and motor vehicle accident trauma
(Benight, Cieslak, Molton, & Johnson, 2008) indicating that CSE may have a more
clearly identified role in posttraumatic recovery.
It is also clear that experiencing a traumatic event is not sufficient to develop
significant disruptions as a result of that experience (Bonano, 2004). Recent research
63
investigating the concept of resiliency following trauma has supported the notion that the
experience of a traumatic life event alone is not an efficient factor cause long term psychological distress (Bonanno, 2004) and that there are many factors that influence
resiliency such as age, gender, education, and social support among others (Bonanno,
Galea, Bucciarelli, & Vlahov, 2007). In addition, traumatic life experiences may shatter
the assumptions we have about the world (Janoff Bulman, 1992), leading to posttraumatic distress, but not all events will necessitate the search for new meaning in life (Emmons, Colby, & Kaiser, 1998). For example, a severe motor vehicle accident may shatter the assumption of a just world in that someone may have positive self perceptions and experience a negative event. However, that event may not serve as an impetus to search for a new meaning in life. Before the event, the individual may have had a relative meaning in life that was conceptualized as being a good parent (Battista & Almond,
1973) in which the event would not necessarily threaten the individual’s life meaning.
However, a traumatic event such as a rape that occurs to an individual that may consider his/her identity as a paragon of purity may have a more salient threat to personal meaning in life.
The intended role of MSE in the context of posttraumatic coping processes is to identify a possible mechanism to find meaning when the need is present. The search for meaning following traumatic life events can result in long term distress (Davis et al.,
1998; Updegraff et al., 2008). Updegraff et al. (2008) report that following the 9/11
64
terrorist attacks, individuals that were able to find meaning after the attack experienced
less psychological distress and those who were searching for meaning two years after the
event. Other measures, such as the Meaning in Life Questionnaire (Steger et al., 2006)
examine the extent to which has already found or possesses a sense of meaning in life or
are actively searching for meaning. Such measures are important and have highlighted
the importance of finding meaning following trauma but are potentially limited in the
ability to connect the search for meaning to the attainment of meaning. The MSE
capitalizes on the dynamic self regulative process of self efficacy beliefs (Bandura, 1997)
to identify a mechanism that may be modified in the response to traumatic life events.
Therefore, the MSE is an attempt to bridge the gap between the search for meaning and
the actual attainment of meaning.
How would the MSE help an individual that is searching for meaning in life
actually find meaning? Ideally, the MSE can be used as a clinical instrument to identify
an individual’s low perception of his or her ability to generate meaning. Thereby
identifying a potential area of interest in the recovery process and allow for therapy to
focus some clinical attention to enhancing MSE. Southwick et al. (2003) introduced
Logotherapy, psychotherapy focused on healing through meaning (Frankl, 1969), as an
adjunct therapy for treating veterans with PTSD and reported positive results with its
implementation. The implementation helped veterans find something meaningful to pursue that was relative to their own recovery process (Southwick, et al., 2003).
65
However, one on one time in psychotherapy is a very limited resource and should be
spent in the most efficient manner possible. If the individual’s specific experience does
not indicate generating meaning is of particular interest then the clinical attention would be better focused on different aspects of posttraumatic recovery. The brief MSE
inventory can be administered to determine if clinical time spent on generating meaning
is contraindicated.
Limitations
There are several limitations in the development of the MSE scale. The methods
used to develop the scale would have been improved by including measures more
focused on meaning in life for convergent validity such as the Life Regard Index (LRI:
Battista & Almond, 1973), the Purpose in Life Test (PIL: Crombaugh & Maholic, 1964),
or the Meaning in Life Questionnaire (MILQ: Steger et al., 2006). Direct comparison to
existing instruments more specifically designed to measure meaning in life could help
focus the aspects of finding meaning in which the MSE may be associated. This could
enable the identification of the specific aspects of meaning self efficacy beliefs that can be focused on and modified. For instance, if there is an indication that the MSE
consistently associated with self efficacy beliefs regarding identifying a sense of purpose
or acceptance, then these areas can be further developed.
66
In addition, the populations that the MSE has been used to investigate thus far
have been sub clinical. The MSE is premised on the concept that it would have its most
utility in populations that have experienced a greater degree of psychological distress.
Although undergraduate college students do experience significant traumatic life
experiences and associate symptoms (Bernat, Ronfeldt, Calhoun, & Arias, 1998; Marx &
Sloan, 2003;Vrana & Lauterbach, 1994), they are still able to function at a level high
enough to approach the demands of college.
Future Directions
Future investigations of the MSE measure should include an examination of how
it performs in comparison to pre established measures of meaning in the same population. The instrument should also be used in a more clinically distressed population
that may experience more profound reasons to generate meaning. The MSE may
demonstrate a more consistent relationship with posttraumatic distress in a clinical population where the effect of the trauma is causing more pronounced functional
impairment. In addition, prospective studies using the instrument would help clarify if the perceived ability to generate meaning is associated with actually finding meaning in a
natural context. The construct of MSE is conceptualized as a mechanism that may
facilitate how one can find meaning following trauma. To fully validate the construct of
MSE, it is necessary to identify whether individuals searching for meaning after trauma
67
are more likely to find meaning with higher scores on the MSE or less likely with lower
scores on the MSE. Future investigations should also focus on determining the source of
the modest temporal stability. The theory underlying MSE supports a construct that is
dynamic and able to change, but if the instrument is not consistently measuring the
construct in the same manner its utility in research would be questionable. There is not a
clear reason to suspect that MSE would change over a two week interval. In addition,
confirmatory factor analysis should be conducted to determine if the two subscales
identified in the current study are replicated in other populations.
Conclusion
The MSE instrument is a brief instrument developed to assess the perceived ability to generate meaning after experiencing traumatic life events. The MSE displayed good convergent and discrminant validity but the temporal stability of the measure over a two week period was modest. The MSE demonstrated the anticipated negative relationship with posttraumatic distress but the overall effect not strong. It is possible that the observed weak relationship between the MSE and posttraumatic distress may be a result of general low distress in the current sample. Further investigations of the measure in different populations are needed to clarify the role of MSE in meeting the demands of post trauma adaptation.
