Psychological trauma : theory, research, practice and policy最新文献

Objective: Exposure to potentially traumatic events during military service is associated with mental health problems such as posttraumatic stress disorder (PTSD) and depression symptoms. However, knowledge regarding the implications of maladaptive personality traits in psychopathology among female veterans is sparse. The present study aims to use the Diagnostic and Statistical Manual of Mental Disorders, fifth edition-an alternative model of personality disorder, to examine associations between maladaptive personality traits, PTSD and depression symptoms, among female Israeli veterans.

Method: A volunteer sample of female Israeli combat veterans (n = 616) and noncombat veterans (n = 484) responded to self-report questionnaires in a cross-sectional study.

Results: Combat veterans reported higher levels of combat exposure and PTSD symptoms, but not depressive symptoms, than noncombat veterans. Combat veterans also reported lower levels of negative affectivity but higher levels of disinhibition than noncombat veterans. All five traits were positive predictors of PTSD and depression symptoms, with psychoticism constituting the strongest predictor. A moderated-mediation analysis indicated four traits (negative affectivity, detachment, disinhibition, and psychoticism) that had a moderating effect on the relationship between combat exposure and PTSD symptoms, and two of the traits (antagonism and disinhibition) that had a moderate effect on the relationship between combat exposure and depressive symptoms.

Conclusions: Maladaptive personality traits play an important role in psychological distress following female veterans' combat service. Future prospective research is necessary to determine the temporal associations between preenlistment maladaptive personality traits and postdeployment mental health of veterans.

Objective: Although research has been conducted in the last decade distinguishing between meaning in life and life satisfaction, no research has examined whether their potential moderating role in mental health problems is distinct. Among military personnel, mental health is paramount, and suicide is one of the leading causes of death.

Method: Data were collected to determine the potential moderating effects of meaning in life and/or life satisfaction of battlefield experiences on depression, anxiety, and thoughts about death (including suicidal ideation). Data were collected on 851 total military personnel, spanning two distinct survey administrations, who reported at least one combat deployment.

Results: Findings suggest that meaning in life has a significant moderating effect on the impact of life-threatening experiences on anxiety and thoughts about death (including suicidal ideation), but no moderating effect on depression. Life satisfaction had no significant moderating role for any mental health outcome.

Conclusions: This research suggests that meaning in life is a significant buffer against certain negative mental health outcomes stemming from life-threatening experiences. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: The present research examines the disparities among Ukrainians residing in the United States, comparing Ukrainians who migrated before the February 2022 Russian invasion against those who arrived afterward. We compare these two cohorts vis-a-vis anxiety, depressive symptoms, optimism, posttraumatic stress, life satisfaction, family economic stress, cultural stress (discrimination, negative context of reception, and language stress), hazardous alcohol use, and domestic violence perpetration and victimization.

Method: The present sample included 703 Ukrainians (53.63% women) residing in the United States. We conducted a series of multivariate analyses of variance using arrival cohort (pre- vs. postinvasion) and gender (male vs. female) as independent variables.

Results: Results indicated that postinvasion participants reported greater internalizing symptoms, cultural/economic stress, and hazardous alcohol use, whereas preinvasion arrivals reported greater levels of optimism and life satisfaction. No significant interactions between cohort and gender emerged for any of the outcomes.

Conclusion: Our findings offer valuable insights into the mental health and well-being of displaced Ukrainians within the backdrop of ongoing conflicts. These findings have significant implications for support and intervention efforts not only for Ukrainians but also for other crisis migrant groups.

Objective: Mindfulness training can relieve posttraumatic stress disorder (PTSD) symptoms in military veterans and others but is inconsistently accessible. Self-guided mobile apps could improve access but their acceptability, feasibility, and benefits for veterans with PTSD have not been established. We conducted a pilot randomized trial of Mindfulness Coach (MC), a free, publicly available, trauma-informed mobile app tailored to veterans.

Method: U.S. veterans with PTSD (n = 173) were randomized to self-guided use of MC or waitlist control (WLC) with 8-week follow-up. Clinical outcomes were PTSD symptoms (PTSD Symptom Checklist-5), depression symptoms (Patient Health Questionnaire, nine item), and psychosocial functioning (Brief Inventory of Psychosocial Functioning). Primary analyses were intent-to-treat using linear mixed models with maximum likelihood estimation. App uptake, objective usage, and usability ratings measured acceptance and feasibility.

Results: Participants varied in age, gender, and ethnoracial identity; most reported recent mental health care utilization. Although study attrition was high (68.4% overall) due to participant dropout (treatment: 43.0%; control: 43.7%) and technical study issues (23% overall), diagnostic tests showed no evidence of bias due to missingness. Study completers (MC: n = 19; WLC: n = 37) showed medium effects on PTSD symptoms (b = -9.31, d = -0.69) and depression (b = -3.10, d = -0.52). Higher-intensity users showed greater benefits. App engagement trended lower for women and minoritized subpopulations. No changes were observed in psychosocial functioning. Usability and helpfulness ratings were favorable.

Conclusions: Transdiagnostic clinical benefits indicate promise for MC as a public health resource for veterans with PTSD. Further study is warranted to confirm these benefits and ensure consistent engagement across subpopulations. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Exposure to potentially traumatic events is well-known to disrupt cognitions about the self. Among trauma-exposed college students, negative cognitions about the self can include low self-worth and heightened perception of behavioral control over outcomes (i.e., self-controllability), including overevaluation of self-control over weight, shape, and eating behaviors. Thus, posttraumatic cognitions may increase risk for eating pathology. These associations may be particularly heightened among those whose trauma was of a sexual nature, given the stigma and inaccurate rape myths that often place the blame on sexual violence survivors rather than perpetrators. Consistent with these possibilities, the present study tested whether sexual violence history moderated expected associations between lower self-worth and greater eating pathology and between greater self-controllability and eating pathology.

Method: Participants were 1,303 trauma-exposed college students (71.6% cisgender women) who completed self-report measures. Two linear regression models were examined, controlling for gender identity and posttraumatic stress symptom severity.

Results: As expected, more negative views toward the self were associated with greater eating pathology, and this association was stronger among college students who had experienced sexual violence compared with those who only experienced other trauma types. In contrast, beliefs about behavioral control over outcomes were unrelated to eating pathology regardless of trauma type.

Conclusions: Findings point to low self-worth as a cognitive target for future research and clinical efforts aimed at addressing trauma-related distress and eating pathology concurrently, especially among individuals with a history of sexual violence.

Objective: The primary objective of this study was to identify healing strategies directly from women who experienced sexual assault and sexual exploitation. The second objective was to explore secondary themes related to healing from sexual assault. This study included two quantitative objectives. The first was to examine if the frequency of reported sexual assault experienced predicted greater coping strategies and if rape that occurred in juvenile years and during college uniquely predicted reported use of more coping strategies.

Method: Using a mix-method design of college women who endorsed experiencing unwanted sexual contact as part of a survey, 283 provided details about healthy healing strategies. Qualitative responses were transcribed verbatim, and thematic classification followed an iterative process. Linear regressions were used to examine the relationships between sexual assault frequency and use of coping strategies.

Results: The most frequently endorsed categories as being helpful to one's healing were social support, proactive behavioral strategies, forgetting/ignoring/shifting focus, positive cognitive strategies, and counseling. Other themes related to healing included long-term effects, unsuccessful strategies, and posttraumatic growth. Secondary themes include validation, denial of/modified recognition of sexual assault, and specific campus environmental factors. Individuals who reported more sexual assault reported using more healing strategies.

Conclusions: This study underscores the benefits of social support and specific strategies. Results suggest a positive relationship between the number of unwanted sexual experiences and coping strategies utilized. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: Muslims living in the United States (MLUS), a highly heterogeneous group, experience high rates of discrimination that may cumulatively contribute to traumatic stress. This study explored whether identity-based discrimination (i.e., due to religion, gender, race) was individually and cumulatively associated with psychological distress and exposure to trauma among MLUS.

Method: Fifty-nine MLUS completed the survey at two time points (~1 year apart). We administered measures of discrimination (at Time 1), distress (at Times 1 and 2), and trauma exposure (at Time 2). Multiple linear regressions determined whether discrimination at Time 1 was associated with traumatic exposure or distress at Time 2, after controlling for covariates. Mediation analyses determined whether the relationship between cumulative discrimination and distress at Time 2 occurred via distress at Time 1.

Results: MLUS who reported experiencing both religious and racial discrimination also reported greater exposure to traumatic events, after controlling for covariates. All three forms of identity-based discrimination (religion, race, gender) were individually and cumulatively (i.e., experiencing all three) associated with distress at Time 1, but not Time 2. However, the relationships between cumulative discrimination at Time 1 and distress at Time 2 were mediated by distress at Time 1. U.S.-born Muslims were particularly at risk for experiencing discrimination, distress, and traumatic exposure.

Conclusion: Experiences of discrimination may have a cumulative impact on trauma and psychological distress among MLUS. This study underscores the need for targeted interventions that assess MLUS clients' discriminatory experiences to develop a more holistic conceptualization, better support systems, and the most effective approaches.

Objective: Childhood mistreatment (CM)/victimization, posttraumatic stress disorder (PTSD), and lifetime substance-use disorders (LT-SUD) are major behavioral health concerns. Their associations were established in mainstream populations but remain under-investigated in Latinx Americans. This study aimed to model the mediating effect of PTSD in the link between CM and LT-SUD among Latinx Americans.

Method: Using a nationally representative sample (N = 2,554) from the National Latinx and Asian American Study, three path models were performed for the whole-group, U.S.-born, and foreign-born Latinx (aged 18 or over), controlling for known predictors for Latinx' mental health.

Results: Latinx reported high rates of childhood physical (32%) and sexual (11.8%) abuse. Latinx subgroups significantly varied in educational attainment, LT-SUD, income, English proficiency, and self-reported discrimination. A fully constrained multiple group path analysis demonstrated direct effects of childhood physical mistreatment (CPM) and childhood sexual mistreatment to lifetime PTSD; PTSD significantly mediated the relationship between CPM with LT-SUD. No significant differences in path coefficients were observed among the Mexican, Cuban, and Puerto Rican subgroups.

Conclusions: Findings suggest that CPM may contribute to using substance to avoid physical and emotional pain, which lends support for the self-medication hypothesis. Latinx who were traumatized by both physical and sexual abuse are more likely to use substances as a negative coping strategy. The study underscores the need for assessing the role of substance use as a coping mechanism for Latinx individuals who have experienced childhood traumatic victimization.

Objective: Over the past few decades, there has been a substantial increase of interest worldwide in how trauma can cause posttraumatic changes such as posttraumatic growth (PTG) and posttraumatic depreciation (PTD), and whether there exist gender-specific patterns of such changes. Despite the increase in interest, no studies have yet examined PTG and PTD in gender stratified models.

Method: Latent profile analysis was used to explore PTG and PTD using the Posttraumatic Change Scale-Short Form in a gender stratified sample of Afghanistan veterans (n = 6,205, 8.3% females). Associations between profiles and predictors (trauma type), and outcome variables (anxiety, depression, and posttraumatic stress symptoms) were explored using R3STEP and Bolck-Croon-Hagenaars procedures in Mplus.

Results: A three-profile model was found to be the best fitting model for female veterans, while a five-profile model was optimal for the male veterans, indicating there are gender-specific patterns in posttraumatic change. For both females and males, higher loads of trauma exposure were associated with conforming to the depreciation profiles, however, growth-related profiles also reported more trauma experiences than the no-change profile. Belonging to the depreciation profiles was associated with higher symptoms of anxiety, depression, and posttraumatic stress for both female and male veterans.

Conclusion: A person may experience posttraumatic depreciation in one life domain, and at the same time growth in another. Male and female veterans differ in their unique profiles of posttraumatic change. Awareness of idiosyncratic profiles of growth and depreciation may improve postdeployment support and intervention strategies. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Objective: The objective of this article is to explore the relationships between two significant predictors, as indicated by existing literature, of posttraumatic stress disorder (PTSD) symptoms: guilt and alexithymia. The investigation centers on a clinical sample of women who have encountered intimate partner violence (IPV).

Method: A total of 740 women who had experienced IPV (M_age = 42.84, SD = 11.092) were recruited to participate in this study. Mediation analysis was employed to examine the mediating role of guilt and alexithymic difficulties in the relationship between IPV and PTSD symptoms.

Results: The findings of this study provide empirical support for the mediating effects of guilt and alexithymia in the link between IPV and PTSD symptoms. Specifically, higher levels of guilt and alexithymia were found to be associated with an increased likelihood of experiencing symptoms of PTSD among women with an IPV experience.

Conclusion: The results of this study have important implications for the development of interventions tailored to the specific needs of women who have experienced IPV. In particular, interventions that target and address guilt and alexithymia hold promise for effectively mitigating symptoms of PTSD in this population. By addressing these underlying factors, interventions can help women navigate their trauma, facilitate emotional processing, and support their journey toward recovery and well-being.
