The Physician's Role in Managing Acute Stress Disorder The Physician’s Role in Managing Acute Stress Disorder MICHAEL G. KAVAN, PhD; GARY N. ELSASSER, PharmD; and EUGENE J. BARONE, MD Creighton University School of Medicine, Omaha, Nebraska Acute stress disorder is a psychiatric diagnosis that may occur in patients within four weeks of a traumatic event. Features include anxiety, intense fear or helplessness, dissociative symptoms, reexperiencing the event, and avoidance behaviors. Persons with this disorder are at increased risk of developing posttraumatic stress disorder. Other risk factors for posttraumatic stress disorder include current or family history of anxiety or mood disorders, a history of sexual or physical abuse, lower cognitive ability, engaging in excessive safety behaviors, and greater symptom severity one to two weeks after the trauma. Common reactions to trauma include physical, mental, and emotional symptoms. Persistent psychological distress that is severe enough to interfere with psychological or social functioning may war- rant further evaluation and intervention. Patients experiencing acute stress disorder may benefit from psychological first aid, which includes ensuring the patient’s safety; providing information about the event, stress reactions, and how to cope; offering practical assistance; and helping the patient to connect with social support and other services. Cogni- tive behavior therapy is effective in reducing symptoms and decreasing the future incidence of posttraumatic stress disorder. Critical Incident Stress Debriefing aims to mitigate emotional distress through sharing emotions about the traumatic event, providing education and tips on coping, and attempting to normalize reactions to trauma. However, this method may actually impede natural recovery by overwhelming victims. There is insufficient evidence to recom- mend the routine use of drugs in the treatment of acute stress disorder. Short-term pharmacologic intervention may be beneficial in relieving specific associated symptoms, such as pain, insomnia, and depression.Am ( Fam Physician. 2012;86(7):643-649.

  • What We Mean When We Talk About Suffering—And Why Eric Cassell Should Not Have the Last Word
    What We Mean When We Talk About Suffering—and Why Eric Cassell Should Not Have the Last Word Tyler Tate, Robert Pearlman Perspectives in Biology and Medicine, Volume 62, Number 1, Winter 2019, pp. 95-110 (Article) Published by Johns Hopkins University Press For additional information about this article https://muse.jhu.edu/article/722412 Access provided at 26 Apr 2019 00:52 GMT from University of Washington @ Seattle What We Mean When We Talk About Suffering—and Why Eric Cassell Should Not Have the Last Word Tyler Tate* and Robert Pearlman† ABSTRACT This paper analyzes the phenomenon of suffering and its relation- ship to medical practice by focusing on the paradigmatic work of Eric Cassell. First, it explains Cassell’s influential model of suffering. Second, it surveys various critiques of Cassell. Next it outlines the authors’ concerns with Cassell’s model: it is aggressive, obscure, and fails to capture important features of the suffering experience. Finally, the authors propose a conceptual framework to help clarify the distinctive nature of sub- jective patient suffering. This framework contains two necessary conditions: (1) a loss of a person’s sense of self, and (2) a negative affective experience. The authors suggest how this framework can be used in the medical encounter to promote clinician-patient communication and the relief of suffering. *Center for Ethics in Health Care and School of Medicine, Oregon Health and Science University, Portland. †National Center for Ethics in Health Care, Washington, DC, and School of Medicine, University of Washington, Seattle.

  • Anger Management Techniques
    Anger Management Techniques 1. Drain the Brain WHEN to use: When your temper begins to flare. WHAT does it do: Mentally challenge yourself before taking out your anger on others HOW? Ask yourself these questions: o WHAT is the source of my irritation? o WHAT is the degree of my anger? o WHAT is the other person’s actual role in the situation? . Turn the circumstances around to see how you would want to be treated if the other person felt as you do. These mental gymnastics can help you regain control over runaway emotions before they escape and cause external damage. 2. Walk It Off WHEN to use: o In those moments when you feel the familiar rage start to rumble, excuse yourself if others are present and take a quick walk down the hall or outdoors, depending on whether you are at home or at work, and the weather conditions. o Even a 5-10 minute stroll, especially one that is fast- paced, will help to cool your irritation as you practice the fight-or-flight strategy by escaping the potential conflict, which is one of the more popular and useful anger management techniques. Anger Management Techniques 1.Count to 20 before saying anything. 2.Leave the room for several minutes, or hours, if necessary, before discussing sensitive issues that may provoke your anger. 3.Write out a response to a problem before tackling it orally or in debate. This will give you time to think about the best approach to a problem rather than responding with random anger.

SOCIAL EMOTIONAL LEARNING THROUGH DEPRESSION EDUCATION IN A HIGH SCHOOL SETTING Antonette Minniti 125 Pages Education on depression is an important part of social emotional learning. Lacking emotion regulation skills tend to lead to larger problems, such as academic struggles, disconnect from peers, strife at home and trouble in interpersonal relationships. Research in depression education or educational programs connected to mental health literacy are minimal, especially at the high school level. The purpose of this research focused on examining the impact of one depression education program, John Hopkins Hospital’s Adolescent Depression Awareness Program (ADAP). The ADAP is a three-day program that informs students about the facts of depression, how it is treated, and what to do if the individual students or someone they know needs help with depression.

  • A Manager's Guide Following a Traumatic Event
    A Manager’s Guide Following a Traumatic Event As a manager or supervisor, you play an important role in providing support to employees following a traumatic event or critical incident. During this time, your staff may experience a variety of changes in productivity and conduct. Employees will need emotional support and understanding while you focus on maintaining a stable work environment. How you respond to these demands is vital. Your company can help you and your employees work toward returning to the pre-trauma level of functioning. Reviewing this guide can help you anticipate and prepare for common employee responses to trauma and severe stress. As a manager, remember that you are also affected by stress in the workplace. We encourage you to use any Employee Assistance Program resources for yourself as well. About Critical Incident Stress Management What is a “Critical Incident?” A critical incident is an abnormal or traumatic event “which has the potential to overwhelm one’s usual coping mechanisms resulting in psychological distress and an impairment of normal adaptive functioning.”1 In the workplace, this might be an event that could result in deficits in employee conduct or productivity. Examples of critical incidents in the workplace include: suicide; homicide; robbery; assault; threats of violence; worksite accidents; industrial and natural disasters; and organizational changes like restructuring or reductions in force. Critical incidents may affect a few individuals or an entire company. What is Critical Incident Stress Management (CISM)? CISM describes a wide array of services designed to support individuals who have experienced a critical incident. A CISM team addresses incidents that impact the workplace.

  • About Emotions There Are 8 Primary Emotions. You Are Born with These
    About Emotions There are 8 primary emotions. You are born with these emotions wired into your brain. That wiring causes your body to react in certain ways and for you to have certain urges when the emotion arises. Here is a list of primary emotions: Eight Primary Emotions Anger: fury, outrage, wrath, irritability, hostility, resentment and violence. Sadness: grief, sorrow, gloom, melancholy, despair, loneliness, and depression. Fear: anxiety, apprehension, nervousness, dread, fright, and panic. Joy: enjoyment, happiness, relief, bliss, delight, pride, thrill, and ecstasy. Interest: acceptance, friendliness, trust, kindness, affection, love, and devotion. Surprise: shock, astonishment, amazement, astound, and wonder. Disgust: contempt, disdain, scorn, aversion, distaste, and revulsion. Shame: guilt, embarrassment, chagrin, remorse, regret, and contrition. All other emotions are made up by combining these basic 8 emotions. Sometimes we have secondary emotions, an emotional reaction to an emotion. We learn these. Some examples of these are: o Feeling shame when you get angry. o Feeling angry when you have a shame response (e.g., hurt feelings). o Feeling fear when you get angry (maybe you’ve been punished for anger). There are many more. These are NOT wired into our bodies and brains, but are learned from our families, our culture, and others. When you have a secondary emotion, the key is to figure out what the primary emotion, the feeling at the root of your reaction is, so that you can take an action that is most helpful. .

  • Anger, Murder, Adultery and Lust!
    Mind Blown Lesson 2: Anger, Murder, Adultery and Lust! [Reader: group leader] We’re in the second lesson of a series on the Sermon on the ​ ​ Mount (Matthew 5, 6 and 7). Jesus was the preacher of that sermon, and He said some pretty mind-blowing things. In the first study we read how Jesus said the whole Old Testament centered around Him. Imagine some preacher telling you that in this day and age. Your reaction might be something like that of the kids in this video whose parent hadn’t told them the identity of Darth Vader. Watch Mind=Blown Star Wars Video In this lesson, we’ll see what Jesus has to say about murder, anger, adultery and lust. Hint: It’s not just going to be mind-blowing; it’s going to be completely counter-cultural! But first, let’s be a little counter-cultural ourselves and open in prayer. [Leader prays.] Part 1: MURDER, HATRED, REVENGE AND ANGER [Reader: person with the longest hair)] ​ ​ Here’s what Jesus’ had to say about murder in the Sermon on the Mount: “You have heard that our ancestors were told, ‘You must not murder. If you commit murder, you are subject to judgment.’ But I say, if you are even angry with someone, you are subject to judgment! If you call someone an idiot, you are in danger of being brought before the court. And if you curse someone, you are in danger of the fires of hell. So if you are presenting a sacrifice at the alter in the Temple and you suddenly remember that someone has something against you, leave your sacrifice there at the alter.

  • QUESTION 20 Despair We Next Have to Consider the Vices Opposed to Hope
    QUESTION 20 Despair We next have to consider the vices opposed to hope: first, despair (desperatio) (question 20) and, second, presumption (praesumptio) (question 21). On the first topic there are four questions: (1) Is despair a sin? (2) Can despair exist without unbelief? (3) Is despair the greatest of sins? (4) Does despair arise from listlessness (acedia)? Article 1 Is despair a sin? It seems that despair is not a sin (desperatio not sit peccatum): Objection 1: As is clear from Augustine in De Libero Arbitrio, every sin involves turning toward some changeable good, combined with turning away from the unchangeable good. But despair does not involve turning toward any changeable good. Therefore, it is not a sin. Objection 2: What arises from a good root does not seem to be a sin, since, as Matthew 7:18 says, “A good tree cannot bring produce bad fruits.” But despair seems to proceed from a good root, viz., fear of God, or horror at the magnitude of one’s sins. Therefore, despair is not a sin. Objection 3: If despair were a sin, then, in the case of the damned, their despairing would be a sin. But this is not imputed to them as a sin (non imputatur eis ad culpam); instead, it is imputed to their being damned. Therefore, it is not imputed as a sin to those who are in this life, either (neque viatoribus imputatur ad culpam). And so despair is not a sin. But contrary to this: That through which men are induced to sin seems to be not only a sin, but a principle of sins.

  • 1 December 19, 2019 the Psychology of Online Political Hostility
    The Psychology of Online Political Hostility: A Comprehensive, Cross-National Test of the Mismatch Hypothesis Alexander Bor* & Michael Bang Petersen Department of Political Science Aarhus University August 30, 2021 Please cite the final version of this paper published in the American Political Science Review at https://doi.org/10.1017/S0003055421000885. Abstract Why are online discussions about politics more hostile than offline discussions? A popular answer argues that human psychology is tailored for face-to-face interaction and people’s behavior therefore changes for the worse in impersonal online discussions. We provide a theoretical formalization and empirical test of this explanation: the mismatch hypothesis. We argue that mismatches between human psychology and novel features of online environments could (a) change people’s behavior, (b) create adverse selection effects and (c) bias people’s perceptions. Across eight studies, leveraging cross-national surveys and behavioral experiments (total N=8,434), we test the mismatch hypothesis but only find evidence for limited selection effects. Instead, hostile political discussions are the result of status-driven individuals who are drawn to politics and are equally hostile both online and offline. Finally, we offer initial evidence that online discussions feel more hostile, in part, because the behavior of such individuals is more visible than offline. Acknowledgements This research has benefitted from discussions with Vin Arceneaux, Matt Levendusky, Mark Van Vugt, John Tooby, and members of the Research on Online Political Hostility (ROHP) group, among many others. We are grateful for constructive comments to workshop attendees at the Political Behavior Section of Aarhus University, at the NYU-SMAPP Lab, at the NYU Social Justice Lab, at the Hertie School, and to conference audiences at APSA 2019, HBES 2019, and ROPH 2020.
