  • Personality Associations with Mood, Hoarding, Health and Well-Being Janet Katherine Spittlehouse
    Personality Associations with Mood, Hoarding, Health and Well-being Janet Katherine Spittlehouse A thesis submitted for the degree of Doctor of Philosophy Department of Psychological Medicine University of Otago, Christchurch New Zealand 31 August 2016 Abstract Background: Personality has been of interest since ancient times. Hippocrates, also known as ‘The father of Western Medicine’ was possibly the first to document the association between personality and mental and physical health by describing the ancient medical theory of Humourism. Over the last 100 years the study of personality has been evolving and there are many different perspectives. Trait perspectives have become popular but they lack any underlying theory about how personality develops. Psychobiological models offer descriptions of personality and provide testable theories on how biology influences their development. A robust psychobiological model is Cloninger’s psychobiological theory and it provided the basis for this project. Objectives: This project explored the associations of personality in different mental health settings using the Temperament and Character Inventory (TCI; Cloninger, Przybeck, Svrakic, & Wetzel, 1994), the personality inventory developed by Cloninger and colleagues, that is suitable for measuring both normal and abnormal personality. The TCI was used to examine the impact of depression on personality measurement and personality associations to self-reported physical and mental health, mood disorders, hoarding behaviours and well-being. Methods: Participants for this project were from three studies. Two randomised clinical trials designed to examine predictors of treatment response for depressed outpatients using either antidepressant medication (N=195) or psychotherapy (N=177) were used to examine the impact of depression on measures of personality.

  • Personality Traits As Risk Factors of Depression and Anxiety Among Japanese Students ᮢ
    Personality Traits as Risk Factors of Depression and Anxiety Among Japanese Students ᮢ Tomomi Matsudaira and Toshinori Kitamura Kumamoto University The aim of this study is to examine the effects of personality (tempera- ment and character) on specific depression and specific anxiety. A total of 541 Japanese undergraduates were investigated by using the Tempera- ment and Character Inventory (TCI) and the Hospital Anxiety and Depres- sion (HAD) scale. Hierarchical multiple regression analyses demonstrated that specific depression was predicted by lower Reward-Dependence, Per- sistence, Self-Directedness, Cooperativeness, and Self-Transcendence; spe- cific anxiety was predicted by higher Novelty-Seeking, Harm-Avoidance, Persistence, and Self-Transcendence, and lower Self-Directedness. Imma- turity of Self-Directedness is a risk factor for negative affectivity. Imma- turity of all character dimensions is a risk factor for specific depression. The relationship between Harm-Avoidance and depression in previous studies may be linked partly to somatic symptoms that were deliberately eliminated in the HAD scale. © 2005 Wiley Periodicals, Inc. J Clin Psy- chol 62: 97–109, 2006. Keywords: personality; temperament; character; depression; anxiety The relationship between personality traits and depressed or anxious moods has been studied in several models (Beck, Epstein, & Harrison, 1983; Clark, Watson, & Mineka, 1994; Cloninger, 1986; Eysenck, 1957, 1967; Gray, 1981; Larsen & Ketelaar, 1991; Tel- legen, 1985). Among many personality traits, neuroticism was strongly related to Major Depression in terms of lifetime prevalence and severity (Duggan, Lee, & Murray, 1990; Scott, Eccleston, & Boys, 1992). However, individuals who had higher neuroticism and lower extroversion exhibited higher anxiety (Gershuny & Sher, 1992). The severity of Generalized Anxiety Disorder was positively associated with the traits of anxiety and neuroticism and was negatively associated with extroversion (Gomez & Francis, 2003).

S Van Gestel1 and C Van Broeckhoven1 1Department of Molecular Genetics, Flanders Interuniversity Institute for Biotechnology (VIB8), University of Antwerp (UIA), Antwerpen, Belgium For centuries, scientists are intrigued by the differences in personality between individuals. As early as in the ancient Greek civilization, people tried to formulate theories to systematize this diversity. With the increased interest in behavior genetics, personality was also considered a challenging phenotype. From the early start, studies suggested a heritable component in personality. After the successes of molecular genetic studies in unraveling the genetic basis of (mostly) monogenic diseases, the focus shifted towards complex traits, including psychiatric disorders. It was observed in several studies that personality measures differed between patients with psychiatric disorders and healthy controls. Therefore, normal personality was considered a viable endophenotype in the search for genes involved in psychiatric disorders such as affective disorders, ADHD and substance dependence. Genes that were to be found in studies on personality could be candidate genes for particular psychiatric disorders. In the course of time, however the study of genes for personality turned out to be at least as hard as the search for genes involved in other complex disorders. In this review, past studies, present problems and future directions concerning the study of personality genetics are discussed.

We conducted a meta-analysis of existing studies to provide formal statistical measures of the strength of the linked polymorphic region of the serotonin transporter gene (5-HTTLPR)– anxiety relationship. For the entire collection of 26 studies, results provided no support for a relationship between anxiety and the presence of the short form of the 5-HTTLPR polymorphism. There was strong evidence of the presence of moderating variables, however, and subsequent analysis revealed that choice of the measure of trait anxiety was significant. Studies using the Neuroticism scale of Costa and McCrae were found to produce a small positive effect (d¼0.23). Other potential moderators (country of study origin, type of subject) did not have a meaningful impact on d statistics. These findings indicate that 5-HTTLPR may in fact have a small but reliable influence on personality, particularly in the manifestation of trait anxiety when measured with a neuroticism scale based on the five-factor model of personality.

  • (Tci-R): Descriptive and Factor Structure in Different Age Levels1
    Behavioral Psychology / Psicología Conductual, Vol. 18, Nº 2, 2010, pp. 385-401 THE TEMPERAMENT AND CHARACTER INVENTORY REVISED (TCI-R): DESCRIPTIVE AND FACTOR STRUCTURE IN DIFFERENT AGE LEVELS1 Anton Aluja, Angel Blanch, Salvador Gallart and Joan-Marc Dolcet University of Lleida (Spain) Abstract This study was aimed to evaluate the psychometric properties and the relationship of age with the answers, internal consistency and factorial structure of the TCI-R. The questionnaire was responded by a sample of 928 voluntary subjects (396 males and 532 women), with a mean age of 30 years old. The participants under 30 scored substantially higher in Novelty Seeking, and to a lesser extent in Reward Dependence, while aged subjects scored significant higher in Harm Avoidance, Self-Directiveness and Cooperation. The global coefficients of factorial congruence were higher than 0.90 in all age groups. The goodness-of-fit indexes in the CFA were unsatisfactory for the simple structure models, although improved when considering secondary loadings. Implications for further research with the TCI-R are discussed. KEY WORDS: TCI-R, factorial analysis, personality models, confirmatory factor analysis, Personality aging difference. Resumen Este estudio fue diseñado para evaluar algunas propiedades psicométricas del “Inventario de temperamento y carácter-revisado” (TCI-R), como la consistencia interna y la estructura factorial en función de diferentes grupos de edad.
