Comparative effectiveness of evidence-based psychotherapies for PTSD delivered in VA residential PTSD treatment.

BACKGROUND: Cognitive Processing Therapy (CPT) and Prolonged Exposure (PE) are first-line treatments for posttraumatic stress disorder (PTSD). There have been few direct comparisons of CPT and PE intended to determine their comparative effectiveness, none of which have examined outcomes among military veterans receiving these treatments in a residential setting such as the Department of Veterans Affairs (VA) residential rehabilitation treatment programs (RRTPs). Such work is essential given that these veterans are among the most complex and severely symptomatic patients with PTSD treated in VA. In this study we compared changes in PTSD and depressive symptoms across admission, discharge, four months and 12 months following discharge among veterans who received CPT or PE within VA RRTPs. METHODS: Using linear mixed models conducted on program evaluation data derived from the electronic medical record and follow-up surveys, we compared self-reported PTSD and depressive symptom outcomes among 1130 veterans with PTSD who were treated with individual CPT (n = 832, 73.5%) or PE (n = 297, 26.5%) in VA PTSD RRTPs in fiscal years 2018-2020. RESULTS: PTSD and depressive symptom severity did not significantly differ at any time points. The CPT and PE groups both showed large-sized reductions in PTSD (CPT d = 1.41, PE d = 1.51) and depression (CPT d = 1.01, PE d = 1.09) from baseline to 12-month follow-up. CONCLUSIONS: Outcomes for PE and CPT do not differ among a highly complex population of veterans with severe PTSD and several comorbid conditions that can make it difficult to engage in treatment.

Patient and provider barriers, facilitators, and implementation preferences of intimate partner violence perpetration screening.

BACKGROUND: The substantial prevalence and consequences of intimate partner violence (IPV) underscore the need for effective healthcare response in the way of screening and follow up care. Despite growing evidence regarding perspectives on healthcare-based screening for IPV experiences (i.e., victimization), there is an extremely limited evidence-base to inform practice and policy for detecting IPV use (i.e., perpetration). This study identified barriers, facilitators, and implementation preferences among United States (US) Veterans Health Administration (VHA) patients and providers for IPV use screening. METHODS: We conducted qualitative interviews with patients enrolled in VHA healthcare (N = 10) and focus groups with VHA providers across professional disciplines (N = 29). Data was analyzed using thematic and content analyses. RESULTS: Qualitative analysis revealed convergence between patients' and providers' beliefs regarding key factors for IPV use screening, including the importance of a strong rapport, clear and comprehensive processes and procedures, universal implementation of screening, and a self-report screening tool that assesses for both IPV use and experiences concurrently. CONCLUSIONS: Findings provide foundational information regarding patient and provider barriers, facilitators, and preferences for IPV use screening that can inform clinical practice and next steps in this important but understudied aspect of healthcare.

Psychometric Properties of the Multidimensional Schizotypy Scale and Multidimensional Schizotypy Scale-Brief: Item and Scale Test-Retest Reliability and Concordance of Original and Brief Forms.

We conducted 2 studies examining the psychometric properties of the Multidimensional Schizotypy Scale (MSS) and the Multidimensional Schizotypy Scale-Brief (MSS-B). These studies offered the first examination of the scales' test-retest reliability (dependability), impact of testing interval on test-retest reliability, and concordance of the 2 versions. The MSS and MSS-B contain positive, negative, and disorganized schizotypy subscales that reflect current models of schizotypy. In Study 1, MTurk participants (n = 245) completed the scales at 2 assessments across a 7-week time interval. Test-retest reliabilities (intraclass correlations) ranged from .84 to .90 for the MSS subscales and from .77 to .85 for the MSS-B subscales, and were unaffected by the interval length between administrations. The association between the same subscales of the MSS and MSS-B across the 2 assessments ranged from .79 to .87, indicating good correspondence between the MSS and MSS-B. Scores on the MSS-B subscales in Study 1 were derived from the full-length MSS. Therefore, we replicated the findings using the actual MSS-B subscales in Study 2 in 3 samples (total n = 339). The results indicated that the MSS and MSS-B have good internal consistency and test-retest reliabilities (dependability), and that there is high concordance between the full-length and brief versions.

For Whom the Mind Wanders, and When, Varies Across Laboratory and Daily-Life Settings.

Undergraduates ( N = 274) participated in a weeklong daily-life experience-sampling study of mind wandering after being assessed in the lab for executive-control abilities (working memory capacity; attention-restraint ability; attention-constraint ability; and propensity for task-unrelated thoughts, or TUTs) and personality traits. Eight times a day, electronic devices prompted subjects to report on their current thoughts and context. Working memory capacity and attention abilities predicted subjects' TUT rates in the lab, but predicted the frequency of daily-life mind wandering only as a function of subjects' momentary attempts to concentrate. This pattern replicates prior daily-life findings but conflicts with laboratory findings. Results for personality factors also revealed different associations in the lab and daily life: Only neuroticism predicted TUT rate in the lab, but only openness predicted mind-wandering rate in daily life (both predicted the content of daily-life mind wandering). Cognitive and personality factors also predicted dimensions of everyday thought other than mind wandering, such as subjective judgments of controllability of thought. Mind wandering in people's daily environments and TUTs during controlled and artificial laboratory tasks have different correlates (and perhaps causes). Thus, mind-wandering theories based solely on lab phenomena may be incomplete.

Unraveling PTSD: Symptom cluster change during and 1 year after veterans' residential PTSD treatment.

OBJECTIVE: Although treatment of posttraumatic stress disorder (PTSD) is effective in reducing symptom severity, remission rates are low. One potential underlying reason for treatment ineffectiveness is differential response of specific PTSD symptom clusters. Using data from a national Veterans Affairs (VA) residential PTSD treatment cohort, we conducted a longitudinal study to examine changes in Diagnostic and Statistical Manual of Mental Disorders, fifth edition PTSD symptom clusters from admission to 1-year follow-up. METHOD: PTSD symptom data were analyzed from a national cohort of veterans who completed VA PTSD residential treatment between October 2019 and September 2020 (n = 1,648; 13% women; median age 44.2 years). Endorsement (%) and severity (M[SD]) of PTSD clusters and individual symptoms were compared at admission, discharge, 4-month and 1-year follow-ups. RESULTS: Large magnitude reductions in all four PTSD symptom clusters were observed from admission to discharge and both follow-ups; however, endorsement of all symptom clusters remained high. Intrusions (Cluster B) were the most highly endorsed at discharge and follow-up, whereas avoidance symptoms (Cluster C) were the least highly endorsed. Differential patterns of change were observed among the 20 individual PTSD symptoms; for example, flashbacks decreased during treatment, but increased to near admission levels by 1-year postdischarge. CONCLUSIONS: Results suggest that intrusive symptoms may be more resistant to residential treatment for PTSD and contribute to lower likelihood of treatment success. Future work is needed to examine differential treatment response for PTSD clusters, to inform the improvement of current and creation of novel treatment interventions, and to better address intrusive symptoms to maximize PTSD treatment gains.

Clinical significance of novel 8-factor model of DSM-5 PTSD in national VA PTSD residential treatment data: Internally- v. externally-cued intrusions.

BACKGROUND: Intrusion symptoms are a core defining feature of posttraumatic stress disorder (PTSD). It was recently proposed that intrusions may be comprised of two distinct underlying processes: internally-cued intrusions (e.g., trauma-related memories), and externally-cued intrusions (e.g., reactivity to trauma-related cues in one's environment). This is the first study to examine the functional correlates of these two intrusion clusters. METHODS: Participants included 7460 veterans discharged from 40 Veterans Affairs PTSD residential programs across the United States in fiscal years 2018 through 2020. Latent network modeling and structural equation modeling were used to assess the fit of an 8-factor model of PTSD symptoms, which were assessed using the PTSD Checklist for DSM-5 (PCL-5) PTSD symptoms at admission, and its association with symptoms of depression and generalized anxiety, and emotional and physical functioning. RESULTS: The 8-factor model, with separate intrusion factors, showed superior model fit to the DSM-5 4-factor, 5-factor dysphoric arousal, 6-factor anhedonia, and 7-factor hybrid models of PTSD. Internally-cued intrusions were uniquely associated with dysphoric arousal, decreased avoidance, and worse physical health functioning; whereas, externally-cued intrusions were uniquely associated with greater avoidance, anxious arousal, negative affect, increased generalized anxiety symptoms, and worse emotional functioning. LIMITATIONS: Limitations include the cross-sectional design and use of self-report measures. CONCLUSIONS: Findings provide initial support for the clinical utility of a novel 8-factor model of PCL-5 PTSD symptoms, which distinguishes internally- and externally-cued intrusions. These separate intrusion symptom clusters may offer greater specificity and utility in informing the prognosis of and tailored interventions for PTSD.

Clinical outcomes of veterans affairs residential PTSD treatment for PTSD and depressive symptoms: 1-year follow-up outcomes and gender differences.

OBJECTIVE: The long-term effectiveness of Department of Veterans Affairs (VA) residential treatment for posttraumatic stress disorder (PTSD), and how it may vary for men and women veterans, is unknown. This is the first national investigation of symptom change from admission, discharge, 4 months, and 1-year postdischarge from VA PTSD residential rehabilitation treatment programs (RRTPs). METHOD: Participants included all veterans discharged from 40 VA PTSD RRTPs October 1, 2017-September 30, 2020 (n = 2,937; 14.3% women). Linear mixed models examined PTSD and depressive symptoms across time points; it was hypothesized that women veterans would experience greater symptom reduction during and after treatment. RESULTS: Overall, veterans reported large-sized reductions of PTSD symptoms at all time points (Cohen's d: discharge = 1.23, 4-month follow-up d = 0.97, 1-year follow-up d = 1.51). Treatment effects for depressive symptoms were large-sized at all time points (Cohen's d; discharge = 1.03, 4-month follow-up d = 0.94, 1-year follow-up d = 1.05). Women veterans showed greater improvement in PTSD and depressive symptom severity (p < .001) than men at discharge, but not at 4-month or 1-year follow-ups. CONCLUSIONS: Veterans reported significant reductions in PTSD and depressive symptoms, and treatment gains were maintained one year postdischarge. Women experienced greater benefit during, but not after, treatment. Results not only provide support for the effectiveness of VA residential treatment for PTSD but also highlight the continued need for strategies to maximize and maintain treatment gains.

Intimate partner violence among lesbian, gay, and bisexual veterans.

The present study describes intimate partner violence (IPV) perpetration and victimization alongside theoretically associated variables in a sample of lesbian, gay, and bisexual veterans. We conducted bivariate analyses (chi-square tests and independent t test) to examine whether the frequencies of IPV perpetration and victimization varied by demographic characteristics, military sexual trauma, alcohol use, and mental health symptoms. Out of the 69 lesbian, gay, and bisexual (LGB) veterans who answered the questions on IPV, 16 (23.2%) reported some form of IPV victimization in the past year, and 38 (55.1%) reported past-year perpetration. Among the 43 veterans who reported psychological IPV, roughly half (48.9%) reported bidirectional psychological IPV, 39.5% reported perpetration only, and 11.6% reported victimization only. LGB veterans who reported bidirectional psychological IPV in their relationships were younger and reported greater symptoms of posttraumatic stress disorder symptoms and depression. The results presented here call for universal screening of IPV perpetration and victimization to both accurately assess and ultimately intervene among all veterans. Inclusive interventions are needed for all genders and sexual orientations, specifically interventions that do not adhere to gendered assumptions of perpetrators and victims.

Military Sexual Trauma and its Association with Mental Health Among Sexual Minority and Heterosexual Veterans in the United States.

Purpose: The purpose of this study was to examine the prevalence of military sexual trauma (MST) by sexual orientation, characteristics of sexual minority (SM) and heterosexual veterans who have experienced MST, and associations between sexual orientation and mental health symptoms among veterans who have experienced MST. Methods: Data were analyzed from a nationally representative web-based survey of 4069 U.S. veterans (4.9% SM), which assessed sociodemographic (e.g., age, sexual orientation) and military (e.g., branch) characteristics, and lifetime and current mental health symptoms. Bivariate analyses compared sociodemographic and military characteristics and mental health symptoms among veterans who have experienced MST by sexual orientation. Multivariable logistic regressions examined associations between sexual orientation and mental health symptoms among veterans who have experienced MST, while controlling for differences in sociodemographic characteristics and non-MST traumatic events. Results: The prevalence of MST (7.5% of weighted sample) was higher among SM veterans compared to heterosexual veterans, with bisexual/pansexual/queer veterans endorsing the highest prevalence (22.7%), followed by gay/lesbian (17.0%) and heterosexual (6.5%) veterans. SM veterans who experienced MST were more likely than heterosexual veterans to screen positive for lifetime and current posttraumatic stress disorder (odds ratio [OR] = 3.06 and 3.38, respectively), and current drug use disorder (OR = 3.53). Conclusions: This study adds to growing evidence that mental health symptoms associated with MST disproportionately impact SM veterans relative to heterosexual veterans. Approaches to reducing barriers and tailoring MST-related care to SM veterans, including through addressing cumulative effects of minority stress, are discussed.

The effect of military sexual trauma on competitive employment status following veterans health administration supported employment services.

Military sexual trauma (MST) is prevalent, and some initial evidence suggests it is associated with impaired employment outcomes. The Veterans Health Administration (VHA) offers supported employment (SE) and Community-Based Employment Services (CBES), which consist of individualized employment support integrated with mental health treatment. The objective of this study was to examine the prevalence and effect of MST on competitive employment outcomes following participation in SE or CBES. Participants were a national set of Veterans who participated in VHA SE or CBES services between 2015 and 2019 and whose medical record contained a completed MST screen (N = 12,689). Data were obtained from clinician-administered SE and CBES admission and discharge forms merged with electronic health records. One thousand five hundred fifteen (11.9%) Veterans reported experiencing MST: 6.2% (n = 676) of men and 47.8% (n = 839) of women. Veterans who experienced MST were significantly less likely to hold competitive employment at discharge, 568 (41.0%) versus 4,702 (47.4%) of those without MST history; χ² = 19.79, p < .001. In adjusted analyses, MST was associated with lower likelihood of competitive employment over and above psychiatric comorbidities and other variables associated with employment status, such as receipt of disability, previous unemployment, homelessness, incarceration, and medical comorbidity. Findings suggest that Veterans seeking employment services may represent a high-risk group for having experienced MST and reinforce the importance of trauma-informed care. Providers should assess for and incorporate MST into treatment planning and job development when indicated. More work is needed to inform employment support for Veterans who have experienced MST.

Risk for PTSD symptom worsening during new PTSD treatment episode in a nationally representative sample of treatment-seeking U.S. veterans with subthreshold PTSD.

Previous research has examined risk factors associated with poorer treatment outcomes for military Veterans with PTSD. However, work has not examined risk for symptom worsening among Veterans with subthreshold PTSD. The aim of this study was to examine demographic, psychiatric, physical health, and pre-treatment PTSD symptom clusters associated with clinically significant worsening of PTSD among a nationally representative sample of United States (U.S.) Veterans with subthreshold PTSD. Participants were Veterans (weighted N = 3162; unweighted N = 236) with subthreshold PTSD entering a new episode of treatment at U.S. Veterans Affairs PTSD specialty clinics during fiscal years 2018 and 2019. Data was collected as part of the Veterans Outcome Assessment, a yearly baseline and 3-month follow-up telephone survey. Analyses used weighted calculations to support the use of VOA data to draw inferences about all eligible Veterans, and binary logistic regression was used to examine risk factors for symptom worsening. Over 1/3 (37.7%) of Veterans with subthreshold PTSD experienced clinically significant symptom worsening from baseline to follow-up. Adjusted analyses revealed several risk factors for symptom worsening, including demographic (e.g., male sex, White race), psychiatric (personality and anxiety disorders), health care utilization (e.g., more primary care encounters in the previous year), physical health disability, and specific baseline PTSD symptom clusters (negative affect and anxious arousal). Findings suggest that Veterans with subthreshold symptoms seeking treatment for PTSD are at risk for symptom worsening, and highlight the importance of assessment, prevention, and treatment in targeting veterans with PTSD symptoms below the diagnostic threshold.

Racial Disparities in Clinical Outcomes of Veterans Affairs Residential PTSD Treatment Between Black and White Veterans.

OBJECTIVE: Racial disparities across various domains of health care are a long-standing public health issue that affect a variety of clinical services and health outcomes. Mental health research has shown that prevalence rates of posttraumatic stress disorder (PTSD) are high for Black veterans compared with White veterans, and some studies suggest poorer clinical outcomes for Black veterans with PTSD. The aim of this study was to examine the impact of racial disparities longitudinally in the U.S. Department of Veterans Affairs (VA) residential rehabilitation treatment programs (RRTPs). METHODS: Participants included 2,870 veterans treated nationally in VA PTSD RRTPs in fiscal year 2017. Veterans provided demographic data upon admission to the program. Symptoms of PTSD and depression were collected at admission, discharge, and 4-month follow-up. Hierarchical linear modeling was used to examine symptom change throughout and after treatment. RESULTS: Black veterans experienced attenuated PTSD symptom reduction during treatment as well as greater depression symptom recurrence 4 months after discharge, relative to White veterans. CONCLUSIONS: This study adds to the body of literature that has documented poorer treatment outcomes for Black compared with White veterans with PTSD. Although both Black and White veterans had an overall reduction in symptoms, future research should focus on understanding the causes, mechanisms, and potential solutions to reduce racial disparities in mental health treatment.

Binge drinking following residential treatment for posttraumatic stress disorder among veterans with and without alcohol use disorder.

Posttraumatic stress disorder (PTSD) is complicated by high rates of problematic drinking and comorbid alcohol use disorder (AUD). This study examined veterans seeking residential PTSD treatment, comparing those with and without AUD, to determine whether trauma type and/or PTSD symptom changes during treatment were associated with binge drinking at 4-month follow-up. Analyses compared characteristics of veterans (N = 758) in residential treatment, as well as associations of demographic, trauma, and alcohol-related variables, with binge drinking episodes at follow-up. Results showed no differences in PTSD symptom improvements based on AUD diagnosis. Among AUD-diagnosed veterans, 21.3% endorsed binge drinking 4 or more (14.3% endorsed 9 or more) days, while 10.8% of veterans without AUD endorsed binge drinking 4 or more (5.2% endorsed 9 or more) days at follow-up. Among AUD-diagnosed veterans, while PTSD symptom improvements were not associated with binge drinking outcomes, drinking days at admission and military sexual trauma (MST) predicted a greater likelihood of binge drinking. Among veterans without AUD, drinking days at admission, PTSD symptom increases, being unmarried, 'other' race, and less education, were associated with a higher likelihood of binge drinking, while MST and combat exposure predicted a lower likelihood of binge drinking. In conclusion, drinking days at admission is a predictor of binge drinking following treatment; thus, alcohol use should be assessed at intake and addressed among those who endorse drinking to reduce the likelihood of alcohol resumption following residential treatment. Furthermore, among AUD-diagnosed veterans, despite PTSD symptom decreases during treatment, MST predicted a greater likelihood of 9 or more binge drinking days at follow-up.

A Longitudinal Investigation of Military Sexual Trauma and Perinatal Depression.

Introduction: Military sexual trauma (MST), which includes sexual harassment or assault while in the military, is prevalent among women Veterans and associated with depression and suicide. Little is known about women Veterans' perinatal mental health, including the potential role of MST. This is the first study to investigate the impact of MST on risk of depression and suicidal ideation (SI) during and after pregnancy. Methods: Bivariate statistical tests between MST harassment and assault, measured by the two standard Veterans Health Administration screening questions, and pre- and postnatal depression and SI, measured by the Edinburgh Postnatal Depression Scale, were examined using longitudinal data from the ongoing Center for Maternal and Infant Outcomes Research in Translation (COMFORT) study. COMFORT includes 620 Veterans interviewed during pregnancy; 452 have been reinterviewed after delivery. Hayes mediation models were employed to examine whether prenatal depression mediated the association between MST and postnatal depression. Results: MST was associated with higher pre- and postnatal symptoms of depression and SI. Further, prenatal depression mediated the association between MST and postnatal depression (indirect effect [standard error] of harassment on postnatal depression through prenatal depression: 1.11 [0.26], p < 0.001; indirect effect [standard error] of assault on postnatal depression through prenatal depression: 1.50 [0.35] p < 0.001), even after controlling for demographic variables and prenatal stress. Conclusions: Women Veterans who have experienced MST may be at higher risk of perinatal depression and SI. Findings highlight the importance of access to mental health care and trauma-informed obstetrical care for these Veterans.

Perceived Stress Mediates the Association between Deployment Sexual Trauma and Nicotine Dependence in Women Veterans.

BACKGROUND: Rates of smoking and related health consequences are higher for women veterans as compared with their civilian counterparts, and trauma is a known risk factor associated with smoking. Military sexual trauma is prevalent among women veterans and associated with deleterious health outcomes, including tobacco use. However, research has not examined variables that may explain this association. The purpose of the present study was to examine the association between deployment sexual trauma (DST; military sexual trauma that occurs during deployment) and nicotine dependence, and whether perceived stress is a potential explanatory variable (i.e., mediator) in this relationship. METHODS: Cross-sectional associations and Hayes mediation models were examined using baseline interview data from the Survey of Experiences of Returning Veterans sample (352 recently returned women veterans). RESULTS: DST was associated with postdeployment nicotine dependence and greater perceived stress. Further, perceived stress was a significant mediator between DST and binary nicotine dependence (indirect effect [standard error] of DST on nicotine dependence through perceived stress, 0.04 [0.01]; 95% confidence interval, 0.01-0.07; odds ratio, 1.04; p < .01) when controlling for education. CONCLUSIONS: Findings suggest that perceived stress may be a clinical target for decreasing nicotine dependence among women veterans who have experienced DST.

Sex Differences in Associations Between Depression and Posttraumatic Stress Disorder Symptoms and Tobacco Use Among Veterans of Recent Conflicts.

Background: Rates of tobacco use, posttraumatic stress disorder (PTSD), and depression are higher for veterans compared to their civilian counterparts. Female veterans have high rates of tobacco use and mental health (MH) conditions; however, little is known about sex differences in the association of depression and PTSD symptoms with postdeployment tobacco use. Methods: Cross-sectional associations and binary logistic regression models were conducted using baseline interview data from the Survey of Experiences of Returning Veterans sample (850 recently returned veterans; 352 women; age mean [standard deviation, SD] = 35.63 [8.94]; 71.2% white). Results: Men were more likely to be tobacco users (39.8% vs. 23.6%; chi square = 24.40; p < 0.001) and had higher postdeployment PTSD symptoms (men mean [SD] = 48.62 [17.93], women mean [SD] = 45.95 [18.22], t = -2.12, p < 0.05), but had similar rates of depression compared to women. In binary logistic models, sex, depression, and PTSD symptoms showed significant main effects in the prediction of postdeployment tobacco use, over and above the effects of demographics, military variables, and alcohol use. Sex moderated the association between PTSD symptoms and tobacco use, such that PTSD symptoms predicted tobacco use for women, but not for men. Sex did not moderate the association between depression and tobacco use. Conclusions: Given the divergent predictors of postdeployment tobacco use for male and female veterans, there may be sex-specific barriers to tobacco-use cessation, including factors related to MH conditions such as PTSD. Further examination of sex differences can help to identify tailored intervention strategies.

Association of multidimensional schizotypy with psychotic-like experiences, affect, and social functioning in daily life: Comparable findings across samples and schizotypy measures.

The present study examined the associations of positive, negative, and disorganized schizotypy with psychotic-like experiences, affect, and social functioning in daily life using experience sampling methodology (ESM) in 2 samples (ns = 165 and 203) that employed different measures of schizotypy. Schizotypy is a useful framework for understanding schizophrenia-spectrum psychopathology, and ESM offers a powerful approach for assessing schizotypy in real-world settings. Participants were signaled 8 times daily for 7 days to complete ESM questionnaires. As hypothesized, positive schizotypy was robustly associated with psychotic-like experiences in daily life, whereas negative schizotypy was associated with negative experiences, diminished positive affect, and social disinterest in both samples. As expected, disorganized schizotypy was associated with disorganization in daily life. Furthermore, it was associated with increased negative affect and diminished positive affect. Thus, positive, negative, and disorganized schizotypy were associated with unique, hypothesized patterns of experiences in daily life, and the findings across the two samples and two schizotypy measures were strikingly consistent. Note that when disorganized schizotypy was not entered as a predictor in the 2 samples, disorganized experiences and negative affect in daily life were associated with positive schizotypy. However, when disorganized schizotypy was included as a predictor, these daily life experiences were associated with disorganized, not positive, schizotypy. This is similar to findings from interview and questionnaire studies that have simultaneously assessed positive, negative, and disorganized schizotypy. The findings support the construct validity of the multidimensional model of schizotypy and the importance of including disorganization in the conceptualization and assessment of schizotypy.

Differential item functioning of the Multidimensional Schizotypy Scale and Multidimensional Scale-Brief across ethnicity.

Schizotypy refers to traits or symptoms similar to schizophrenia, but in a diminished form, and schizotypy is thought to reflect a liability for the future development of schizophrenia. The Multidimensional Schizotypy Scale (MSS) is a new measure of schizotypy that improves on existing measures. The MSS contains full and brief subscales for positive, negative, and disorganized schizotypy. Although MSS scores have been validated in a variety of populations, the scales have not been thoroughly examined for differential item functioning in East Asian, Southeast Asian, Hispanic, Multiracial, and White participants. The current study included 567 East Asian, 351 Southeast Asian, 360 Hispanic, 230 Multiracial, and 345 White undergraduate participants from the United States. Overall, few of the items in the full or brief versions of the scales displayed differential item functioning across groups. The full and brief versions of the scales also displayed similar and not-significantly different validity coefficients with the Detachment and Psychoticism scales of the Personality Inventory for DSM-5. These findings suggest that the MSS measures the same constructs across ethnic groups, and the scale scores represent the same latent level of schizotypy among groups. Future research may use the MSS in these diverse groups without concern that the psychometric properties differ significantly among groups.

Comparing the effectiveness of VA residential PTSD treatment for veterans who do and do not report a history of MST: A national investigation.

The Department of Veterans Affairs (VA) has implemented initiatives to promote veterans' recovery from the health sequelae of military sexual trauma (MST), including posttraumatic stress disorder (PTSD). MST can impact emotion regulation, interpersonal functioning, and perceptions of trust and safety, as well as increase risk for psychiatric comorbidity, which may impede PTSD treatment.. VA PTSD Residential Rehabilitation Treatment Programs (RRTPs) may facilitate the therapeutic process by offering increased structure, support, and adjunctive services. Limited research has examined the effect of MST on PTSD RRTP outcomes. Utilizing data from 7918 men and women veterans participating in a VA PTSD RRTP, the impact of the experience of MST on rates of program completion and changes in PTSD symptoms during and after treatment were examined. Rates of program completion were similar between those who did and did not report experiencing MST. Multilevel modeling was utilized to examine the impact of MST on PTSD symptoms after accounting for gender, age, race/ethnicity, and program completion. MST survivors endorsed more severe PTSD symptoms at admission; however, PTSD symptom severity scores were similar to those who did not report experiencing MST by discharge. Additionally, MST survivors had larger initial reductions in PTSD symptoms, followed by a greater recurrence of PTSD symptoms over time, compared to those who did not report experiencing MST. MST survivors appear able to participate in and benefit from PTSD RRTPs. Nonetheless, the increased recurrence of PTSD symptoms following discharge from residential treatment indicates the need for strategies to maintain post-treatment gains among MST survivors.

Sex Differences in Military Sexual Trauma and Severe Self-Directed Violence.

INTRODUCTION: Previous research has demonstrated an association between military sexual trauma and risk for suicide; however, risk for self-directed violence such as suicide attempt or nonsuicidal self-injury following military sexual trauma is understudied. This study examines the relationship between military sexual trauma and serious self-directed violence resulting in hospitalization, as well as whether this relationship differs by sex. METHODS: Participants were 750,176 Operations Enduring Freedom/Iraqi Freedom/New Dawn veterans who were enrolled in Veterans Health Administration care during the period of October 1, 2001-September 30, 2014 and who were screened for military sexual trauma. Data were analyzed in 2019. Bivariate analyses and Cox proportional hazards regression models were employed. RESULTS: Women veterans were more likely to screen positive for military sexual trauma (21.33% vs 1.63%), and women and men were equally likely to experience serious self-directed violence (1.19% women vs 1.18% men). Controlling for demographic variables and psychiatric morbidity, military sexual trauma predicted serious self-directed violence for both men and women. Further, men with military sexual trauma were 15% less likely to experience self-directed violence compared with women with military sexual trauma (hazard ratio=0.85, 95% CI=0.74, 0.98). CONCLUSIONS: Military sexual trauma is associated with risk for serious self-directed violence for both men and women veterans, and the relationship may be pronounced among women. Results underscore the importance of incorporating military sexual trauma into treatment and preventative efforts for self-directed violence.
