Research Paper Abstract and Annotated Bibliography: Trauma- and Stressor-Related Disorders

Abstract

This paper examines trauma- and stressor-related disorders, the DSM-5 category whose every diagnosis requires that the person lived through a traumatic or stressful event. It first describes, in the writer's own words rather than the manual's, the category's five disorders, from PTSD and acute stress disorder to adjustment disorders and the two attachment-related disorders of early childhood, and explains how the PTSD criteria changed between editions. It then considers causes from several angles: the type of trauma, risk factors before, during and after the event, heritability shown in twin research, the neuroscience of fear learning, and spiritual dimensions such as moral injury. The evaluation section describes how counselors can assess these disorders through a careful trauma history, self-report checklists and a structured clinical interview. The treatment section reviews evidence for exposure therapy, cognitive processing therapy, cognitive therapy and EMDR, with brief attention to treatment for adjustment and attachment disorders. A biblical perspective follows, drawing on Scripture's honesty about suffering and its picture of restoration, and considering how faith can be both wounded by trauma and a resource for healing. The paper closes with future research needs, including better tools for distinguishing adjustment disorders from normal distress, head-to-head treatment comparisons, research on the childhood attachment disorders and treatments informed by neuroscience. Throughout, the paper emphasizes what these findings mean for clinical mental health counselors, who will meet trauma survivors in nearly every setting, from schools to agencies to private practice.

Brewin et al. (2000) pooled studies of 14 pretrauma, peritraumatic and posttrauma risk factors in adults exposed to trauma. Demographic factors such as gender, age at the time of trauma and race mattered in some samples and not in others, whereas a personal or family history of mental illness and reports of childhood abuse mattered fairly consistently. No single factor was large, yet how severe the trauma was, how little support followed and how much other stress piled on afterward outweighed what the person brought to the event. The meta-analysis is older but remains a standard reference. In the paper, it supports the causes section by showing that environment after trauma matters as much as vulnerability before it.

Written while the DSM-5 criteria were being revised, this review by Bryant et al. (2011) examined whether acute stress disorder, introduced in DSM-IV to identify survivors at high risk in the first month, actually predicts later PTSD. The authors concluded that it misses most people who go on to develop PTSD and that its emphasis on dissociative symptoms was too narrow. They proposed reframing the diagnosis as a description of severe acute stress reactions rather than a precursor. The review is authoritative because its authors shaped the revision. It will support the overview and evaluation sections, explaining how acute stress disorder fits in the category and why early screening needs follow-up.

Casey and Bailey (2011) summarize what is known about adjustment disorders, a common but neglected group of diagnoses. They argue that classifications give little guidance for separating adjustment disorders from normal reactions to stress or from depression and PTSD, which risks both pathologizing ordinary distress and overdiagnosing depression. They also note that adjustment disorders appear frequently among people who die by suicide and carry a poor prognosis in adolescents, and that intervention studies are scarce. The article is a narrative review in a leading journal. It supplies the paper's coverage of adjustment disorders and its future research section, since the authors identify clear gaps.

This systematic review and meta-analysis by Cusack et al. (2016) evaluated 64 trials of psychological treatments for adults with PTSD, rating risk of bias and strength of evidence. Exposure therapy, including prolonged exposure, had high-strength evidence, and cognitive processing therapy, cognitive therapy, mixed cognitive behavioral approaches, EMDR and narrative exposure therapy also showed benefit, with numbers needed to treat below four for losing the diagnosis in several of them. Head-to-head comparisons were too few to rank the treatments, and most studies did not report adverse events. The review's rigorous grading makes it central to the treatment section and to the discussion of what counselors can offer.

Friedman et al. (2011) reviewed the research on the DSM-IV criteria for PTSD in order to recommend changes for DSM-5. They found little empirical support for the criterion requiring fear, helplessness or horror at the time of trauma, reported factor analyses favoring four symptom clusters over three, and documented that survivors often show anger, guilt, shame, dissociation and negative beliefs as well as fear. Their proposals largely became the DSM-5 criteria. As a work group review, it is the best source on why the diagnosis looks as it does. The paper will use it in the overview section to explain the current criteria in my own words.

Kessler, R. C., Aguilar-Gaxiola, S., Alonso, J., Benjet, C., Bromet, E. J., Cardoso, G., Degenhardt, L., de Girolamo, G., Dinolova, R. V., Ferry, F., Florescu, S., Gureje, O., Haro, J. M., Huang, Y., Karam, E. G., Kawakami, N., Lee, S., Lepine, J.-P., Levinson, D., ... Koenen, K. C. (2017). Trauma and PTSD in the WHO World Mental Health Surveys. European Journal of Psychotraumatology, 8(sup5), Article 1353383. https://doi.org/10.1080/20008198.2017.1353383

Drawing on representative surveys in two dozen countries with nearly 69,000 participants, Kessler et al. (2017) examined how PTSD risk differs by type of trauma, assessing PTSD both for each respondent's worst event and for a randomly selected one. About 70% of respondents reported at least one lifetime trauma. Violence by another person was the most dangerous kind of event, and rape, other sexual assault, stalking and a loved one's sudden, unexpected death made up the largest shares of the population burden. The cross-national design and random-trauma method are major strengths. The study anchors the paper's discussion of prevalence and of why assessment must ask about specific kinds of events.

Litz, B. T., Stein, N., Delaney, E., Lebowitz, L., Nash, W. P., Silva, C., & Maguen, S. (2009). Moral injury and moral repair in war veterans: A preliminary model and intervention strategy. Clinical Psychology Review, 29(8), 695-706. https://doi.org/10.1016/j.cpr.2009.07.003

Litz et al. (2009) introduced the concept of moral injury: lasting emotional, psychological, behavioral, spiritual and social harm that can follow perpetrating, failing to prevent or witnessing acts that violate deeply held moral beliefs. Drawing on literature about combat veterans, they offered definitions, a working model and intervention strategies aimed at moral repair. The article is conceptual rather than empirical, which limits its claims, but it has been highly influential. It is the main scholarly support for the paper's discussion of spiritual causes and of a biblical perspective, since guilt, shame and loss of trust in God are central to moral injury.

Ozer et al. (2003) screened 2,647 studies and meta-analyzed 68 that examined seven predictors of PTSD in adults. Every predictor reached significance, yet the three that describe a person's history, earlier trauma, earlier adjustment and family psychopathology, were the weakest at about r = .17, while peritraumatic dissociation had the largest, r = .35. The authors concluded that what happens psychologically during and immediately after the trauma predicts PTSD better than characteristics a person brings to it. The analysis complements the Brewin meta-analysis with a different set of studies. In the paper, it strengthens the causes section and suggests why early responses deserve clinical attention.

Powers et al. (2010) meta-analyzed 13 randomized trials, with 675 participants, comparing prolonged exposure with wait-list or psychological placebo conditions. Prolonged exposure produced a large effect on primary PTSD outcomes, g = 1.08, gains largely held at follow-up, and it did not differ significantly from other active treatments such as cognitive processing therapy and EMDR. The average treated patient did better than 86% of control patients after treatment. One author developed the treatment, which readers should keep in mind, though the analysis follows standard methods. The study will support the treatment section's description of exposure-based therapy.

This review by Ressler et al. (2022) summarizes clinical features, current treatments and the neuroscience of PTSD. It reports a general population prevalence of roughly 6% to 8%, rising to as much as 25% in heavily traumatized groups, and estimates that at least 30% to 40% of the risk is heritable. The authors describe PTSD as involving disrupted fear learning centered on the amygdala, hippocampus and medial prefrontal cortex and outline how genetics and circuit research could lead to new treatments. As a recent review in a major journal, it provides the paper's biological explanation and much of its future research section.

A twin study of genetic and environmental contributions to liability for posttraumatic stress symptoms. Archives of General Psychiatry, 50(4), 257-264. https://doi.org/10.1001/archpsyc.1993.01820160019002

True et al. (1993) studied 4,042 male twin pairs who served during the Vietnam era to separate genetic and environmental influences on self-reported PTSD symptoms. After adjusting for differences in combat exposure, genetic factors still accounted for roughly 13% to 34% of the variance across symptom clusters, while shared family environment contributed nothing measurable. The study is older and limited to male veterans, but it remains a landmark demonstration that heredity shapes vulnerability. The paper will cite it in the causes section alongside the more recent heritability estimate from Ressler et al. (2022), showing how the genetic evidence has developed.

The Clinician-Administered PTSD Scale for DSM-5 (CAPS-5): Development and initial psychometric evaluation in military veterans. Psychological Assessment, 30(3), 383-395. https://doi.org/10.1037/pas0000486

Weathers et al. (2018) describe how the CAPS, the standard clinician interview for PTSD, was rebuilt around the DSM-5 criteria, and they test it in two samples of military veterans. Diagnosis showed strong interrater and test-retest reliability, and severity scores had high internal consistency, alpha = .88, along with good convergent validity with the earlier version of the interview and with the PTSD Checklist. Because the samples were veterans, generalization to civilians needs further study. The article supports the paper's assessment section, where the CAPS-5 is presented as the standard structured interview and paired with self-report checklists for screening and monitoring.

Zeanah and Gleason (2015) review research on reactive attachment disorder (RAD) and disinhibited social engagement disorder (DSED), the two childhood diagnoses in the trauma- and stressor-related category. They trace the history of classification, describe how the disorders differ from secure and insecure attachment patterns, and summarize what is known about causes, especially severe social neglect, and about treatment, which they find limited. The review is selective rather than systematic, but its authors are leading researchers in the area. It allows the paper to cover the whole category rather than PTSD alone and contributes to the evaluation and future research sections.
