Posttraumatic stress disorder (PTSD) disrupts individual well-being and relationship health, particularly among veteran/military couples with heightened risks due to deployment, family reintegration, and traumatic stress. Although cognitive-behavioral conjoint therapy (CBCT) and brief CBCT (bCBCT) have demonstrated strong efficacy in reducing PTSD symptoms, their impact on relational outcomes is less compelling. Given the importance of relationship functioning for veterans' overall health, enhancing interpersonal outcomes of PTSD treatment remains a research priority. One promising approach is the integration of 3,4-methylenedioxymethamphetamine (MDMA)-assisted therapy to augment the relational benefits of established PTSD interventions. This single-site, open-label pilot study evaluated the preliminary benefit, safety, and acceptability of MDMA-assisted bCBCT in eight U.S. military veterans with PTSD and their intimate partners (N = 16). An eight-session MDMA-assisted bCBCT protocol with two MDMA administration sessions and dyadic integration sessions incorporating elements of integrative behavioral couples therapy was delivered. Outcomes included PTSD symptom severity, relationship functioning, and safety. Veterans exhibited large pre-post PTSD symptom reductions, d = 1.25, which were generally maintained during follow-up. Both veterans and partners experienced large improvements in relationship functioning, ds = 1.83 and 1.29, respectively, with moderate rebound during follow-up. No serious adverse events were reported. This first trial of MDMA-assisted bCBCT in U.S. veterans and their partners provides preliminary evidence of potential improvements in PTSD and relational outcomes, with no identified serious safety concerns. This model has potential for future evaluation in large health care systems, leveraging the hypothesized therapeutic effects of MDMA for individuals with PTSD and their families.
This scoping review examined the bidirectional longitudinal association between posttraumatic stress disorder (PTSD) and cardiometabolic health in military populations. Five databases (PubMed, EMBASE, CINAHL, PsycInfo, and ProQuest) were searched from database inception to May 2026 for peer reviewed studies, dissertations and theses, and government reports that reported observational longitudinal analyses of the associations between PTSD and cardiometabolic health variables of interest in adult military samples. Two independent reviewers conducted screening and data extraction. Data were synthesized by cardiometabolic variable. A total of 18 studies were included in the review. Most studies were conducted in the United States, enrolled veterans, and had primarily male samples. When examining whether PTSD predicted cardiometabolic health over time, the findings were mixed for lipids and glucose regulation. Most studies found that PTSD predicted hypertension over time, and one study found that PTSD predicted metabolic syndrome severity. Studies examining PTSD and inflammatory markers bidirectionally typically reported no association. Few studies examined whether cardiometabolic health predicted PTSD over time, with mixed or inconclusive findings across markers. Current longitudinal evidence in military populations suggests that PTSD is a predictor of hypertension, though its associations with other aspects of cardiometabolic health are less clear. Given the limited and mixed findings regarding bidirectional effects, additional prospective studies are needed to better understand the temporal association between PTSD and cardiometabolic health.
Posttraumatic stress disorder (PTSD) care can be delivered in person or via telehealth as well as through computer- and app-based programs. Receiving PTSD care through a preferred modality improves engagement and outcomes, but little is known about veterans' modality preferences. This study describes veterans' preferences for and perceptions of four modalities of PTSD care (i.e., in-person, telehealth, computer-based, app-based) and identifies predictors of preference for digital modalities. Veterans with PTSD (N = 615) completed a survey assessing interest in and perceptions of PTSD care modalities and factors that might influence preferences (e.g., sociodemographic characteristics, psychosocial factors). Veterans were classified into three groups: prefer digital interventions (n = 122), open to digital interventions (n = 180), and not interested in digital interventions (n = 313). Veterans were most interested in in-person care, followed by telehealth, computer-based, and app-based modalities, with substantial variability. One in two veterans preferred or were open to digital modalities, yet few reported prior knowledge of them. PTSD service-connected veterans and those higher in self-stigma of help-seeking were more likely to prefer or be open to digital modalities. Perceptions of and familiarity with in-person, telehealth, and computer-based modalities also predicted preferences. Dissemination recommendations are discussed.
Complex posttraumatic stress disorder (CPTSD) is recognized as a distinct diagnosis in the ICD-11. The International Trauma Questionnaire for Children and Adolescents (ITQ-CA) assesses CPTSD symptoms in youth aged 7-17 years; however, no validated Italian version is currently available. This study evaluated the psychometric properties of the Italian ITQ-CA in 488 children and adolescents from community (n = 432) and high-risk residential-care (n = 56) samples. Confirmatory factor analyses compared competing models, and measurement invariance was tested across sex assigned at birth, age, and risk status. The correlated second-order posttraumatic stress disorder (PTSD) and disturbances in self-organization (DSO) model was the best-fitting admissible hierarchical solution, CFI = .990, TLI = .986, RMSEA = .045. Reliability was good, ω = .866-.900; ωH = .800-.823; OHC = .947-.952. Approximate or partial measurement invariance supported latent-mean comparisons: Girls and adolescents had higher PTSD and DSO means than boys and younger participants, ΔM = .554-.879, whereas risk groups did not differ, ΔM = -.055-.006. Concurrent and convergent associations were moderate to large, and regression models identified partially differentiated external correlates, R2 = .563-.618. The findings support the factorial validity and reliability of Italian ITQ-CA symptom scores and their use in Italian youth, and future research should examine functional impairment, longitudinal validity, and clinical replication.
Emotional inertia, the moment-to-moment carryover of negative affect, has been implicated in psychological maladjustment but remains poorly understood in trauma-exposed individuals. This study examined whether momentary trauma-related intrusions strengthened emotional inertia in trauma-exposed individuals. Trauma survivors (N = 95; European Australian: n = 46, Chinese Australian: n = 49) completed a 7-day ecological momentary assessment (EMA) study, reporting trauma-related intrusions and negative affect four times daily. Multilevel lagged models examined within-person emotional inertia and its interaction with momentary trauma-related intrusions. Negative affect demonstrated significant emotional inertia, B = 0.20, 95% CI [0.15, 0.26], p < .001. Momentary trauma-related intrusions significantly strengthened this effect such that negative affect became more persistent when intrusions were present, B = 0.19, 95% CI [0.06, 0.33], p = .004. The findings suggest that trauma-related intrusions are associated with increased emotional inertia in daily life, potentially reflecting disruptions in affective recovery processes. These results highlight the importance of examining temporal emotional dynamics, beyond mean levels of distress, to understand posttraumatic adjustment.
Trauma-related guilt and shame are common following traumatic or potentially morally injurious events. Improving guilt and shame is often a goal of treatment, and providers express a desire for more strategies to manage guilt and shame for individuals with posttraumatic stress disorder (PTSD) and moral injury. Evidence-based psychotherapies for PTSD, such as prolonged exposure, cognitive processing therapy, and eye movement desensitization and reprocessing therapy, have been found to improve trauma-related guilt and shame among individuals with PTSD and/or moral injury. This paper provides an overview of the assessment of trauma-related guilt and shame, as well as therapist considerations for treatment, and explores each treatment, its evidence, and its approach to treating guilt and shame. Applied techniques and strategies to maximize effectiveness in addressing guilt and shame are provided for each of these treatments. Future research is needed to inform clinical decision-making, the treatment of residual shame and guilt, and the assessment of trauma-related shame and guilt throughout treatment.
Although trauma-focused psychotherapies, such as cognitive processing therapy (CPT), are effective treatments for posttraumatic stress disorder (PTSD), a substantial portion of individuals exhibit a diminished response. Stellate ganglion block (SGB), an anesthetic procedure targeting the sympathetic nervous system, has shown promise for PTSD but has only recently begun to be evaluated as an augmentation to evidence-based psychotherapy. This randomized, placebo-controlled, double-blind pilot trial assessed the efficacy of 1-week accelerated CPT augmented with SGB versus a placebo injection. Of 54 consented individuals, 39 participants (Mage = 38.1 years, SD = 11.0; 69.2% female; 79.5% White) who met the DSM-5 criteria for PTSD were randomized to receive SGB (n = 18) or a saline injection (n = 21), followed by 10 virtual CPT sessions over 5 days. The primary outcome was clinician-assessed PTSD severity (Clinician-Administered PTSD Scale for DSM-5; CAPS-5); secondary outcomes included self-reported PTSD (PTSD Checklist for DSM-5; PCL-5) and depressive symptoms (Patient Health Questionnaire-9; PHQ-9). Of 39 randomized participants, 37 (94.9%) completed treatment. Both groups experienced large improvements in PTSD symptoms, CAPS-5 (baseline-3-months): d = 1.77, PCL-5: d = 1.67, and depressive symptoms, PHQ-9: d = 0.86. Treatment Condition x Time interactions were not significant for the CAPS-5, PCL-5, or PHQ-9, ps = .144-.958. Post hoc comparisons indicated significantly lower PCL-5 scores in the SGB group on Day 1 of CPT, B = -11.99, p = .015. Augmenting accelerated CPT with SGB was highly feasible but did not produce significantly larger symptom reductions compared to placebo.
Chronic pain frequently co-occurs with posttraumatic stress disorder (PTSD). One theory proposes that some chronic pain may reflect pain reexperiencing (i.e., reactivation of somatosensory trauma memories). Although some research supports this theory, evidence from clinical survey studies is limited and methodologically constrained. In this study, 330 trauma survivors reported chronic pain and retrospectively reported peritraumatic pain using digital body maps (108 predefined regions). To reduce confounding from tissue damage-related pain, chronic pain assessment was confined to pain unattributed to injury/illness, and the role of peritraumatic injuries was evaluated. Participants were assessed for PTSD symptoms, age at first trauma exposure, and beliefs about trauma-related origins of their pain. Approximately 67% of participants reported peritraumatic pain, 50% reported chronic pain, and 11% reported chronic pain in the same region(s) as peritraumatic pain (i.e., spatial overlap). Multilevel logistic regression across participants and regions indicated a strong association between peritraumatic and same-region chronic pain, OR = 2.94, independent of trauma-related injuries. PTSD symptom severity and earlier age at trauma were associated with a higher likelihood of spatial overlap. Participants with overlapping pain were particularly likely to endorse a trauma-related pain origin. Results demonstrate spatial associations between peritraumatic and chronic pain, especially among individuals with elevated PTSD symptoms and earlier age at trauma, not attributable solely to injuries. The observed pattern provides support for the pain reexperiencing theory and highlights areas warranting further research. It may be clinically important to distinguish between pain reexperiencing and other posttraumatic pain, as specific trauma-informed approaches may be required.
In racially and economically segregated communities, structural violence and chronic adversity perpetuate the risk for community violence and related trauma exposure. Despite widespread awareness of community violence, urban youth of color are among those least likely to have access to services that promote trauma recovery. When these youth do encounter the mental health system, the focus is often on behavioral control rather than understanding and addressing the continuous traumatic stress they face. This paper, components of which were first presented at the 41st Annual Meeting of the International Society for Traumatic Stress Studies, describes multipronged, interdisciplinary efforts to provide youth and families affected by community violence with trauma-informed, structurally competent services in both office- and community-based settings within an academic medical center that sees one of the highest volumes of bullet-related injuries in the United States.
Individuals with subthreshold posttraumatic stress disorder (PTSD) often experience significant impairment yet face barriers to care (e.g., insurance denials and exclusion from clinical trials) due to strict Diagnostic and Statistical Manual of Mental Disorders (DSM)-based diagnostic criteria that rely entirely on symptom counts. Symptom counts assume all symptoms contribute equally to underlying (within-criterion) severity. Recently, item response theory and nonlinear factor analysis models have been used to estimate PTSD severity, accounting for differences in the relative weight of symptoms. We examined a subset of treatment-seeking adults with comorbid PTSD and substance use disorders in Project Harmony who met the criteria for full PTSD based on weighted severity scores regardless of whether they met the full DSM-defined criteria. Latent class analysis was then used to identify differences in symptom endorsement patterns in this empirically estimated full-threshold PTSD group. Three distinct classes were identified: (a) participants with full-threshold PTSD based on both DSM and weighted classification, (b) underdiagnosed participants who did not endorse either DSM Criterion C (avoidance) symptom, or (c) underdiagnosed participants who only endorsed one DSM Criterion E (alterations in arousal/reactivity) symptom. Endorsement of two DSM Criterion D symptoms (negative alterations in cognitions and mood) did not differ across classes, suggesting that they could be "priority symptoms" indicating high distress and impairment, regardless of DSM diagnostic status or severity level. Accounting for symptom weighting and prioritizing these symptoms in assessment and diagnosis could increase precision in PTSD assessment and ensure equitable access to care.
War profoundly affects the well-being of civilian populations and shapes subsequent mental health outcomes. This study aimed to investigate the effects of continuous traumatic stress (CTS) and coping efficacy on mental health outcomes among adults in Ukraine amid ongoing warfare over time. We examined how changes in CTS responses, coping efficacy, and stressful life events predicted posttraumatic stress disorder (PTSD) symptoms and broad mental health outcomes (depression, anxiety, insomnia, well-being). Participants were 157 adults who experienced war-related stress and completed two online surveys approximately 12 months apart. Moderately small but significant symptom reductions were observed, ds = 0.18-0.32, ps = .005-.026. Structural equation models analyzing the associations between initial status and changes in CTS, coping efficacy, and stressful life events and Time 2 PTSD symptoms and broad mental health outcomes explained most of the variance in PTSD symptoms and broad mental health outcomes, R2 = .84‒.85. Higher initial severity and worsening CTS responses over time predicted higher PTSD symptom severity, standardized estimate (Eststd) = 0.29‒0.32, ps = .001‒.006, and poorer broad mental health outcomes, Eststd = 0.25‒0.28, ps = .001‒.016. Increased stressful life event exposure was linked to worse broad mental health outcomes, Eststd = 0.16, p = .001. Improvements in coping efficacy predicted superior broad mental health outcomes, Eststd = -0.43, p < .001. Assessing and addressing the impact of CTS, considering the toll of stressful life events, and enhancing coping efficacy may help to optimize service delivery in ongoing war environments.
Written exposure therapy (WET) has become increasingly recognized alongside other evidence-based treatments of posttraumatic stress disorder (PTSD), with a rapidly growing evidence base. However, current research has not yet investigated the effect of WET on comorbid depression. We conducted a systematic review to examine the efficacy of WET for comorbid depression among PTSD populations. The primary aim of this review was to investigate WET's effectiveness in reducing depression at posttreatment and follow-up. A review of five major databases, with no language or publication date restrictions, yielded 18 papers that met all inclusion criteria. Due to variability among studies, including study design, population studied, and modifications to WET, we integrated the current literature descriptively. The individual study findings reported an overall reduction in depressive symptoms, with within-group effect sizes ranging from small to large, ds = 0.39-1.43. The noninferiority randomized controlled trial included in the review found that WET was comparable to CPT, d = 0.19. These findings suggest that WET may be effective for reducing depressive symptoms in PTSD populations, and future trials should measure and report depression outcomes to contribute to the WET literature.
High rates of interpersonal violence exposure and trauma-related mental health concerns among women in substance use treatment underscore the need for violence prevention services in these settings. Peer support specialists can play a crucial role in increasing access to trauma-focused services and overcoming barriers, such as stigma and mistrust in formal systems. We tested the feasibility, acceptability, and preliminary efficacy of a peer-delivered sexual and intimate partner violence prevention program for women in substance use treatment (THRIVE: The Healthy Relationships and Interpersonal Violence Education program). We conducted a single-arm trial with 90 women recruited from outpatient and residential substance use treatment centers. Self-report surveys assessed risk and protective factors and violence exposure over four assessment points from baseline (T1) to 3-month follow-up (T4). Exit interviews and survey data examined feasibility and acceptability outcomes. Results from linear mixed models indicated that participants improved on knowledge of consent (MT1 = 4.37, MT4 = 4.52), p = .004, and resources (MT1 = 2.09, MT4 = 2.63), p < .001; increased sexual self-efficacy (MT1 = 4.90, MT4 = 5.29), p < .001; and decreased risky dating (MT1 = 3.37, MT4 = 2.87), p < .001, and physical and psychological intimate partner violence victimization (T1: 73.9%, T4: 42.0%), p < .001. Participants reported high satisfaction and acceptability and highlighted the strengths of peers as facilitators. In sum, THRIVE offers promise as an effective, scalable violence prevention program.
Potentially traumatic events (PTEs) are associated with cardiovascular disease (CVD) in aging populations. Despite sex differences in PTE exposure and CVD incidence, no study has examined sex-specific associations between PTEs and CVD in the same sample of middle-aged and older adults. Using data from the Health and Retirement Study, we examined lifetime exposure to 18 PTEs across three domains: early life adversity, lifetime trauma, and perceived discrimination and CVD (stroke or heart disease). We used Cox proportional hazards regression to calculate crude and adjusted (race/ethnicity, age, and educational attainment) hazard ratios (aHRs) and 95% confidence intervals (CI). Among 12,272 HRS participants, nearly 80% reported experiencing at least one PTE. Within domains, child abuse and serious accident or illness had the strongest associations with CVD for men, aHR = 1.26, 95% CI [1.04, 1.52], aHR = 1.68, 95% CI [1.53, 1.85], respectively, and women, aHR = 1.35, 95% CI [1.17, 1.56], aHR = 1.80, 95% CI [1.64, 1.97], respectively. Sex differences were noted for perceived discrimination-for men, the strongest association was between being prevented from moving into other housing and CVD, aHR = 1.52, 95% CI [1.08, 2.14], and for women, the strongest association was between being denied health care and CVD, aHR = 1.43, 95% CI [1.08, 1.90]. For both sexes, experiencing a higher number of PTEs was associated with an increased rate of CVD. Differences among men and women in these results offer insight into opportunities for prevention and targeted clinical interventions in this age group.
South Asian Americans, one of the largest immigrant groups in the United States, experience trauma and engage in risky behaviors. South Asian Americans may face cultural pressures to suppress positive affect, which could explain the association between posttraumatic stress disorder (PTSD) and risky behaviors. This study used associational variable analysis to examine whether PTSD symptom severity was associated with risky behaviors and if affective responses to positive events explained variance in this association. South Asian American adults who were exposed to trauma (N = 244; Mage = 34.26 years, SD = 8.60; 54.9% men) were recruited through Amazon Mechanical Turk. Three multivariate linear regressions were conducted, each modeling PTSD symptoms, risky behaviors, and one affective response (i.e., positive emotionality, hedonic deficits, or negative affect interference), controlling for age and gender. Significant models were probed for indirect associations. Many participants met the criteria for probable PTSD (48.0%) and engaged in at least one past-month risky behavior (79.0%), including problematic technology use, eating behaviors, and alcohol use (55.7%-60.2%). PTSD symptom severity was positively associated with engagement in risky behaviors, R2 = .79, p < .001, and indirect effects were significant via hedonic deficits, β = .07, bootstrapped 95% CI [.03, .12], and negative affect interference, β = .24, bootstrapped 95% CI [.12, .37]. Findings suggest that PTSD symptoms among South Asian Americans may reflect difficulties in experiencing and sustaining positive affect, which may contribute to risky behaviors. Trauma interventions targeting compromised affective responses may reduce risky behaviors in this population.
Two interventions that tax visuospatial working memory (WM) may reduce intrusive memories despite differing procedurally: playing Tetris with or without memory recall. Accordingly, this study examined how engagement with negative memories influences intrusion frequency (Experiment 1) and WM load (Experiment 2). In Experiment 1 (N = 90), participants viewed a trauma film and were assigned to Tetris without memory recall, Tetris with memory recall, or a no-task control condition. Participants rated memory vividness and unpleasantness before and after the intervention and recorded film-related intrusions in a diary for 1 week. In Experiment 2 (N = 45), a reaction time task assessed whether brief memory reactivation (as used in the Tetris without memory recall condition) or concurrent, deliberate recall (as used in the Tetris with memory recall condition) differentially taxed WM. Experiment 1 showed that the Tetris with memory recall task led to the largest reductions in memory vividness, ηp 2 = .09, p = .017, and unpleasantness, ηp 2 = .09, p = .015, relative to the other conditions, but, unexpectedly, intrusion frequency did not differ between interventions, ηp 2 = .02, BF01 = 5.57, p = .448. Experiment 2 indicated that only simultaneous, deliberate recall imposed a WM load, ηp 2 = .11, p = .032. The lack of effects on intrusive memories warrants consideration of methodological differences between this and prior Tetris research and highlights the need to clarify which elements and mechanisms of the intervention-whether implemented with or without deliberate recall-modulate intrusions before translating these findings into clinical practice.
The special issue on trauma and posttraumatic stress among two-spirit, lesbian, gay, bisexual, trans, queer, intersex, asexual, and people with other diverse gender identities and sexual orientations (2SLGBTQIA+) populations comes amid heightened public health concerns driven by increased stigma and discrimination. In our introduction, we present the articles in the issue, which highlight the complexity of trauma and its effects as experienced by 2SLGBTQIA+ populations. These contributions, which advance science and inform public health research, employ quantitative, qualitative, or longitudinal methods. Areas of focus include: the impacts of non-DSM-5 Criterion A1 events, bisexual and transgender individuals, intersectional discrimination, geographic location, and interventions that respond to traumatic stress among this group. Additionally, the articles emphasize healing and strength through identity, community, and activism. Our introduction to this special issue concludes by highlighting four specific areas that need further attention to improve understanding of trauma and posttraumatic stress among 2SLGBTQIA+ populations: commitment to epistemic justice, research, intervention development, and training and education.
Adverse and benevolent childhood experiences (ACEs and BCEs, respectively) are uniquely associated with posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD); however, there is no systematic review on the mechanisms of these associations. This systematic review and meta-analysis aimed to synthesize studies considering psychological mediators of the associations between ACEs/BCEs and PTSD/CPTSD. Databases (PsychINFO, PubMed, PTSDpubs, PsycARTICLES, and Web of Science) were searched from inception to August 2025 for peer reviewed studies of adult populations examining psychological mediators of the associations between ACEs or BCEs and PTSD or CPTSD. A total of 63 studies involving 31,540 participants met the inclusion criteria. Mediators were grouped into six categories: cognitive beliefs and appraisals (n = 33), emotion regulation strategies (n = 40), interpersonal relationships (n = 7), spiritual and religious beliefs (n = 2), attachment style (n = 5), and dissociation symptoms (n = 9), with mostly small effect sizes. Subcategory meta-analysis revealed emotion regulation, β = .4, 95% CI [0.001, 0.78], and maladaptive coping strategies, β = .05, 95% CI [0.03, 0.07], significantly mediated the association between ACEs and PTSD. Risk of bias and quality of evidence were assessed. Overall, evidence was insufficient to determine how mediators function across pathways, and a paucity of literature is highlighted, considering BCEs and CPTSD.
The PTSD Checklist for DSM-5 (PCL-5) is a commonly used self-report measure of posttraumatic stress disorder (PTSD) symptoms, as outlined in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5). There is promising evidence supporting the reliability and validity of the PCL-5, and numerous studies have examined competing PTSD symptom factor structures as assessed using the instrument. There is limited and mixed evidence, however, about whether the PCL-5 demonstrates measurement invariance across race/ethnicity and gender. This is a potential source of bias given that race/ethnicity and gender are well-established predictors of higher rates of both trauma exposure and PTSD. The present study examined measurement invariance across race/ethnicity and gender in a large, diverse (N = 3,720; 78.6% female, 33.3% Hispanic/Latino, 30.5% Asian/Pacific Islander, 23.1% White/European American, 13.1% Black/African American) sample of young adults who reported trauma exposure. The results support scalar measurement invariance across all race/ethnicity and gender comparisons for both the DSM-5 factor structure and the best-fitting hybrid model. Comparisons of latent mean levels indicated that the largest differences in PTSD symptoms were gender-specific, such that women reported higher overall PTSD symptom levels, as well as higher levels for each DSM-5 symptom cluster, than men, ps < . 001. These results provide promising empirical evidence that although the frequency of trauma exposure may vary significantly across race/ethnicity and gender, the measurement of PTSD symptoms is invariant across these groups.
Standardized trauma assessment frameworks often fail to account for the unique experiences and symptom presentations of minoritized populations, including Black, Indigenous, and people of color (BIPOC) and sexual and gender minority (SGM) individuals, leading to methodological inequity. This paper addresses critical gaps in trauma assessment research practices by examining the limitations of DSM-centric definitions, which exclude systemic, structural, and identity-based trauma exposure and culturally relevant trauma-related distress. We then explore how behaviorally specific language impacts trauma disclosure and reporting discrepancies, noting that traditional labels may lead to the underreporting of sexual violence experiences in SGM and BIPOC communities. Next, we discuss the integration of community-engaged research and intersectional frameworks in developing culturally relevant assessment tools, such as the SGM Adverse Childhood Experiences (SGM‑ACEs) scale. Psychometrically, we then highlight the necessity of establishing measurement invariance to mitigate differential item functioning and measurement bias, ensuring that observed differences in posttraumatic stress disorder symptom severity reflect true clinical variation rather than instrument artifacts. The paper concludes with clinical and policy recommendations, emphasizing cultural humility, the use of validated tools for specific populations, and institutional shifts toward methodological equity to prevent iatrogenic harm and improve outcomes for minoritized individuals.
