Distress tolerance, or the perceived ability to tolerate negative emotional states, is often associated with posttraumatic stress disorder (PTSD) such that higher distress tolerance is generally associated with less severe PTSD symptom levels. As distress tolerance is often considered a risk and maintenance factor in distress disorders, examining the association between changes in distress tolerance and changes in PTSD symptoms may have clinical relevance. The present study examined the associations between PTSD symptom severity and distress tolerance across three assessment points over 12 weeks among 212 patients receiving outpatient psychotherapy services. Using random-intercept cross-lagged panel modeling (RI-CLPM), concurrent and prospective associations between PTSD and distress tolerance were examined. PTSD symptoms at Time 1 and Time 2 significantly predicted distress tolerance at Time 2, β = −.296, and Time 3, β = −.395, respectively. Distress tolerance did not predict subsequent PTSD symptom severity. Exploratory analyses examined distress tolerance and four PTSD symptom clusters over time. Patterns of results differed across clusters, though it was consistent that only PTSD symptom clusters predicted subsequent distress tolerance and not vice versa. The results support the interrelationship of changes in psychopathology and emotional distress tolerance and indicate that distress tolerance may be an important factor in symptom remission during PTSD treatment.

At the 39th meeting of the International Society of Traumatic Stress Studies, three leading researchers and clinicians in technology-enabled traumatic stress support were invited to reflect on their careers and contributions to the field. Dr. Brian P. Marx has led the development of large-scale technologies to screen, assess, and treat traumatic stress pathology across diverse etiologies and needs. Dr. Barbara O. Rothbaum, a pioneer in the development of virtual reality for exposure therapy, has demonstrated the efficacy and scalability of digital treatment for traumatic stress. Retired Col. Dr. Eric Vermetten has worked extensively on the intersection of basic mechanisms, novel psychological and biological treatment, and technology for scalable assessment and treatment, primarily in military and mass casualty contexts. The panelists were asked to reflect on their initial ambitions, concerns, unexpected challenges, and the influence of their work on new research trajectories. Their insights provide valuable lessons about the process and content of their work, and their pioneering efforts have significantly advanced the field of technology-enabled traumatic stress support.

This editorial summary provides an overview of the 39th annual meeting of the International Society for Traumatic Stress Studies (ISTSS) held from November 1–4, 2023. The meeting, themed “Scalable Strategies to Address the Impact of Trauma Worldwide: Innovations and Implementation,” encouraged presenters to focus on the scalability of traumatic stress research and practice. The articles presented at the meeting, which form this issue, cover a broad spectrum of topics, from basic biological mechanisms to innovative digital engagement to population-wide treatments. These articles emphasize eliminating biases in research design and psychiatric practice, promoting health equity, and addressing the unique challenges of traumatic stress. This summary underscores the importance of scalability in developing flexible, dynamic, and inclusive mental health care interventions.

Posttraumatic stress disorder (PTSD) is associated with poor quality of life. Although randomized clinical trial data show improvements in quality of life following trauma-focused therapies (TFTs), including prolonged exposure therapy (PE) and cognitive processing therapy (CPT), less is known about how these improvements are experienced from the trauma survivor's perspective. A national sample of 60 veterans who recently completed TFT as part of routine care at U.S. Department of Veterans Affairs facilities participated in semistructured qualitative interviews during which the impact of treatment on quality of life was explored. Following a mixed deductive/inductive approach, six interrelated themes describing changes in quality of life emerged: full participation in social activities, greater emotional intimacy in relationships, improvements in parenting, expanded engagement in hobbies and community, increased occupational commitment and confidence, and more joy in life. The data highlight the positive impact of treatment on quality of life and provide depth to quantitative findings demonstrating improvements in quality of life following TFT.

Adverse childhood experiences (ACEs) are often associated with higher rates of mental health issues and problematic behaviors within the U.S. college population. Therefore, the primary purpose of this study was to investigate the current associations among ACEs, six psychosocial risk factors for poor health (i.e., anxiety, depression, loneliness, negative urgency, positive urgency, and stress), and significant behavioral and substance problems in a large sample of college students (N = 1,993). Overall, 72.3% of participants reported one or more ACEs, with 21.7% reporting at least five of these experiences; the most prevalent ACE types were emotional abuse (51.7%) and parental mental illness (33.8%). Cumulative ACEs were positively associated with all health risk factors, rs = .07–.38, ps ≤ .001, and these ACE scores were most connected to student problems with alcohol, overeating, and sex, rs = .19–.22, ps < .001. Furthermore, using logistic regression, cumulative ACEs predicted which students were more likely to report behavioral problems, OR = 1.08, 95% CI [1.03, 1.14]; substance problems, OR = 1.16, 95% CI [1.07, 1.26]; and both types of problems, OR = 1.28, 95% CI [1.20, 1.36], relative to students without these problems. Aside from ACEs, higher anxiety was the only other risk factor all three problem types shared. Collectively, these findings highlight the differential impact of ACEs and other psychosocial risk factors on the susceptibility of college students to particular forms of maladaptive coping and suggest potential targets for intervention and prevention efforts in these areas.

Between 44% and 87% of active duty service members and veterans who deployed following the September 11, 2001, terrorist attacks know someone who was killed or seriously injured in combat. Considering the high frequency and known impact of traumatic loss, it is important to understand if and how traumatic loss may impede posttraumatic stress disorder (PTSD) treatment progress in military personnel. Additionally, experiencing a traumatic loss elevates the risk of developing prolonged grief disorder (PGD), which is associated with higher levels of PTSD symptoms, more functional impairment, and more lifetime suicide attempts among military personnel. Given what is known about the association between PGD and PTSD in treatment-seeking service members and veterans, it is also important to understand whether grief-related symptom severity negatively impacts PTSD treatment response. The current study examined associations among traumatic loss, complicated grief, depressive symptoms, and PTSD treatment response among military personnel (N = 127) who participated in variable-length cognitive processing therapy (CPT). There was no direct, F(2, 125) = 0.77, p = .465, or indirect, β = .02, p = .677, association between a traumatic loss index event and PTSD treatment response compared with other trauma types. Prior assessments of depressive symptom severity were directly related to PTSD at later assessments across two models, ps < .001–p = .021 Participants with a traumatic loss index trauma demonstrated significant reductions in complicated grief, depressive symptoms, and PTSD following CPT, ps < .001, ds = −0.61–−0.83. Implications, study limitations, and suggestions for future research are presented.

Prior research has identified traumatic experiences and substance use as risk factors for adolescent engagement in sexual risk-taking; however, these studies have relied upon subthreshold or non–dually diagnosed samples. The present study examined differences in sexual risk behaviors between adolescents with a substance use disorder (SUD) and co-occurring posttraumatic stress disorder (PTSD) versus those with an SUD and another co-occurring psychiatric disorder. Participants were 269 adolescents who met the clinical screening criteria for an SUD and at least one psychiatric disorder. Bivariate comparisons and generalized linear models were used to compare sexual risk behaviors in participants with co-occurring PTSD (30.0%) and those with a different psychiatric disorder (70.0%). Participants with co-occurring PTSD were twice as likely to have multiple sex partners during the same period compared to those without PTSD, odds ratio (OR) = 2.35, p = .012. They also reported, on average, over twice the incidence rate of unprotected sexual encounters, incidence rate ratio (IRR) = 2.06, p = .034, and a 51.0% higher incidence of sexual risk behaviors, IRR = 1.51, p = .008, than participants without co-occurring PTSD. The results suggest dually diagnosed adolescents with co-occurring PTSD are more likely to engage in sexual risk behaviors than those with a different co-occurring disorder, placing them at higher risk for adverse health effects, such as sexually transmitted infections and unplanned pregnancies. As such, this population is likely to benefit from targeted trauma-informed sexual health education programs focused on sexual risk reduction.

The refugee experience is typically characterized by exposure to numerous premigration traumatic events and postmigration stress in the resettlement environment. Refugees’ experiences can lead to elevated rates of psychopathology, including posttraumatic stress disorder (PTSD) and depression. Emotion regulation is a key mechanism contributing to mental health outcomes among refugees. This study examined the impact of age on the association between emotion regulation and critical social outcomes relevant to refugee resettlement, such as social engagement and functional impairment. Participants were 1,081 Arabic-, Farsi-, Tamil- and English-speaking adult refugees. Premigration trauma exposure, postmigration stressors, PTSD symptoms, depressive symptoms, emotion regulation, social engagement, and functional impairment were measured. A series of hierarchical regression and Poisson regression analyses revealed emotion dysregulation as a significant predictor of functional impairment, β = .36, p < .001, and social engagement, Exp B = 0.99, p = .002. A significant interaction between age and emotion dysregulation was associated with both PTSD, β = .05, p = .048 and depressive symptoms, β = .06, p = .010, suggesting a stronger positive association between emotion dysregulation and both PTSD and depressive symptom severity for older individuals. Postmigration stressor exposure, emotion dysregulation, and older age are important factors that may negatively impact social engagement and functional impairment in the resettlement environment. Additionally, higher levels of trauma exposure may negatively impact social engagement. These findings have implications for public health and social services in the context of resettled refugee communities.

Recent national estimates suggest that 1 in 2 women will experience intimate partner violence (IPV) in their lifetime. Given the high prevalence of posttraumatic stress disorder (PTSD) among women experiencing IPV, it is necessary to consider whether PTSD assessments function adequately for this population. Thus, the present study aimed to evaluate the psychometric properties of the past-month version of the PTSD Checklist for DSM-5 (PCL-5), one of the most widely used self-report measures of PTSD symptoms, in a sample of community women experiencing IPV. Participants were 158 women who had experienced IPV in the past 6 months (M_age = 40.14 years, 39.9% White). The PCL-5 demonstrated good internal consistency, Cronbach's α = .97, and scores were significantly positively correlated with theoretically related constructs (i.e., PTSD symptom count on the SCID-5, IPV severity, substance use, depression, anxiety, and emotion dysregulation); however, it demonstrated poor 30-day stability, r = .38, ICC = .55. The ability of the PCL-5 to discriminate with respect to a PTSD diagnosis was acceptable, AUC = .74. A cutoff score of 21 maximized sensitivity (82.5%) and specificity (55.4%); this is lower than typical cutoffs (i.e., 31–33). Although the PCL-5 has generally demonstrated adequate psychometric properties, findings suggest that it does not function optimally for women experiencing IPV relative to its functioning for other trauma-exposed populations. The lower-than-typical cutoff suggests that the PCL-5 may underestimate PTSD prevalence among women experiencing IPV.

Disgust is a common emotional response to trauma but is studied less frequently than fear or other negative emotions. In laboratory settings, individuals with a history of sexual assault report more disgust following exposure to trauma reminders than those exposed to other trauma types, and people with more severe posttraumatic stress disorder (PTSD) symptoms typically report more disgust than those with lower symptom levels. It remains unknown whether this association is also present in ecological contexts and if these associations vary by trauma reminder type. The present sample included 80 trauma-exposed community members (PTSD: n = 39, no PTSD: n = 41) who completed up to 17 prompts per day for 3 days (2,158 total completed surveys). Multilevel models indicated that trauma reminders were associated with increased feelings of disgust, B = 0.16, SE = 0.06, p < .001, which was consistent across trauma reminder types, p < .001–p = .001. PTSD symptom severity moderated the association between trauma reminders and disgust such that it was stronger for participants with higher CAPS-5 scores, B = 0.02, SE = 0.01, p = .011. All trauma reminder types demonstrated the same pattern of moderation, ps = .003–.022, except flashbacks, p = .070. Trauma type was not a significant moderator of any trauma reminder type, ps = .193–.929. These findings suggest that trauma reminders encountered in daily life are associated with feelings of disgust. The results underscore the importance of exploring disgust as a trauma-related emotional experience among trauma survivors.
