A Systematic Review of Social Support Instruments for Measurement-Based Care in Posttraumatic Stress Disorder.

Purpose: Social support is a treatment target for individuals with post-traumatic stress disorder (PTSD) but is not systematically assessed in clinical care. This review evaluated the quality of patient-reported social support instruments used in PTSD research to identify candidates for measurement-based care (MBC) with this population. Method: A systematic review identified all validated measures of social support used in research with traumatized populations after 1990. Instrument development/validation studies were then evaluated using components of the updated COSMIN guidelines. Instruments were rated for clinical utility and evidence of their psychometric properties in use with traumatized individuals was synthesized. Results: Twenty-nine instruments were identified across 231 studies. Evaluation of development articles found 14 instruments with sufficient evidence of content validity and internal consistency reliability that could be considered for clinical use. Of these, nine had comparable properties in traumatized samples and could be preliminarily included in MBC of social support in the treatment of PTSD. Additional studies on measures' responsiveness and test-retest reliability are needed. Conclusions: Existing measures of social support could improve clinical care of PTSD when used routinely to provide feedback on this critical component of health. MBC of social support may also improve clinical care of other psychiatric conditions.

Development of a brief support and education intervention for loved ones of veterans with posttraumatic stress disorder.

Clinical practice guidelines for managing posttraumatic stress disorder (PTSD) encourage incorporating loved ones into treatment, and supportive relationships can increase engagement in mental health care for veterans with PTSD. This study describes the iterative refinement, feasibility/acceptability testing, and national dissemination of a brief support and psychoeducation intervention for loved ones of veterans with PTSD. Loved ones (n = 181; range:1-11 per group) attended and qualitatively rated "PTSD 101 for Family and Friends: A Support and Education Workshop." Open-ended questions were used to gather data on suggestions for improvement and descriptions of helpful content, and the workshop was refined following participant and operational partner feedback using a quality improvement framework. Rating quantitative items on a 1-5 scale, participants found the overall quality (M = 4.76) and relevance (M = 4.82) to be excellent, noting they learned substantial new information (M = 4.45). Sense of support (M = 4.95), intentions to use the material (M = 4.87), PTSD self-efficacy (M = 4.41), and understanding of PTSD (M = 4.76) were rated favorably. Common themes among helpful elements were a sense of shared experience and optimism and increased knowledge of treatments/resources. Suggestions for improvement referenced logistics. Following continual stakeholder feedback and refinement, the workshop represents a novel method for providing loved ones with empirically supported psychoeducation, coping skills, and community. It is being disseminated by the Family Services Section of the Veterans Health Administration Office of Mental Health and Suicide Prevention.

A daily diary study of the romantic partner relationship dynamics associated with anger and other posttraumatic stress disorder symptoms.

Posttraumatic stress disorder (PTSD) is linked to negative relationship outcomes, but the relational processes that link specific PTSD symptoms to these outcomes over granular periods are not well understood. The current study used a daily diary methodology to investigate the associations between specific PTSD symptoms (i.e., anger, avoidance, reexperiencing, hyperarousal, and numbing) and proximal indices of relationship functioning (i.e., accommodation behaviors, disclosure, intimacy). Participants were members of 64 couples, each comprising a male service member (SM) and female romantic partner (RP), who completed daily assessments of PTSD symptoms and indices of relationship functioning for 2 weeks. The results suggest a somewhat unique role of anger on relationship dynamics: Although mean levels of PTSD symptom clusters were associated with negative relationship outcomes at the bivariate level, daily fluctuations in anger were uniquely related to accommodation behaviors and SM- and RP-reported intimacy in multilevel models, Bs = -0.08-0.50). These findings highlight the importance of considering the differential role of specific PTSD symptoms, like anger, in dyadic interventions for PTSD; several strategies for doing so in the context of contemporary evidence-based treatments are discussed.

Minimal important difference metrics and test-retest reliability of the PTSD Checklist for DSM-5 with a primary care sample.

The PTSD Checklist for DSM-5 (PCL-5) is a measure of posttraumatic stress disorder (PTSD) symptom severity that is widely used for clinical and research purposes. Although previous work has examined metrics of minimal important difference (MID) of the PCL-5 in veteran samples, no work has identified PCL-5 MID metrics among adults in primary care in the United States. In this secondary analysis, data were evaluated from primary care patients (N = 971) who screened positive for PTSD and participated in a large clinical trial in federally qualified health centers in three U.S. states. Participants primarily self-identified as women (70.2%) and White (70.3%). We calculated test-retest reliability using clinic registry data and multiple distribution- and anchor-based metrics of MID using baseline and follow-up survey data. Test-retest reliability (Pearson's r, Spearman's ρ, intraclass correlation coefficient) ranged from adequate to excellent (.79-.94), with the shortest time lag demonstrating the highest reliability estimate. The MID for the PCL-5 was estimated using multiple approaches. Distribution-based approaches indicated an MID range of 8.5-12.5, and anchor-based approaches indicated an MID range of 9.8-11.7. Taken together, the MID metrics indicate that PCL-5 change scores of 9-12 likely reflect real change in PTSD symptoms and indicate at least an MID for patients, whereas PCL-5 change scores of 5 or less likely are not reliable. These findings can help inform clinicians using the PCL-5 in similar populations to track patient responses to treatment and help researchers interpret PCL-5 score changes in clinical trials.

A mixed-methods evaluation of why an implementation trial failed to engage veterans with posttraumatic stress disorder in trauma-focused psychotherapy.

An effectiveness trial found that telemedicine collaborative care for posttraumatic stress disorder (PTSD) significantly increased engagement in trauma-focused psychotherapy (TFP) and improved PTSD symptoms. However, in a subsequent implementation trial, very few veterans enrolled in collaborative care initiated TFP. We conducted a mixed-methods evaluation to determine why veterans did not initiate TFP in the implementation trial. After conducting chart reviews of 1,071 veterans with PTSD enrolled in collaborative care, patients were categorized into four mutually exclusive TFP groups: TFP not discussed; TFP discussed, declined; TFP discussed, did not decline; and TFP initiated. We conducted semistructured interviews with 43 unique patients and 58 unique providers (i.e., care managers and mental health specialists). Almost half (48.6%) of the veterans had no documentation of discussing TFP with their care manager; another 28.9% discussed it but declined. Most veterans (77.1%) had an encounter with a mental health specialist, 36.8% of whom never discussed TFP, and 35.7% of whom discussed it but declined. Providers reported that many veterans were not able, willing, or ready to engage in TFP and that non-trauma-focused therapies were better aligned with their treatment goals. Veterans gave numerous reasons for not initiating TFP, including having bad prior experiences with TFP and wanting to avoid thinking about past traumatic experiences. Commonly cited reasons for noninitiation were providers never discussing TFP with veterans and veterans declining TFP after discussing it with their provider. Interventions, such as shared decision-making tools, may be needed to engage providers and patients in informed discussions about TFP.

Associations Between Lifetime Panic Attacks, Posttraumatic Stress Disorder, and Substance Use Disorders in a Nationally Representative Sample.

Objective: Rates of lifetime substance use disorder (SUD) are high among people with lifetime posttraumatic stress disorder (PTSD). Panic attacks are also prevalent among trauma survivors and people with SUD, yet studies on PTSD/SUD have rarely examined comorbid panic. This potentially creates additional barriers to effective treatment for people with PTSD/SUD, in that panic may be under-diagnosed among people with PTSD/SUD and consequently attenuate treatment outcome. Additionally, research on PTSD/SUD often combines people with alcohol use disorder (AUD) and people with drug use disorders (DUDs) into a single group despite evidence that these two PTSD/SUD subgroups differ along important sociodemographic and clinical variables. This study tested the hypothesis that among adults with lifetime PTSD, panic attacks would be associated with greater lifetime risk for both AUD and DUD. We also explored whether panic attacks were associated with specific DUDs that frequently co-occur with PTSD (cannabis, sedatives/tranquilizers, heroin/opioids, and cocaine). Methods: Data were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III), a cross-sectional national study. Adults with lifetime PTSD (N = 2,230) were classified into one of three groups based on diagnostic interview data: adults with PTSD/AUD (i.e., met criteria for PTSD and AUD but not DUD; n = 656), adults with PTSD/DUD (i.e., met criteria for PTSD and DUD, regardless of AUD diagnostic status; n = 643), or adults with PTSD-only (i.e., met criteria for PTSD but not AUD or DUD; n = 1,031). Results: Weighted logistic regression analyses showed that lifetime risk of PTSD/AUD and PTSD/DUD, each relative to PTSD-only, was greater for adults who were younger at the time of data collection, were male, and had a history of panic attacks. Panic attacks did not predict specific DUD diagnoses comorbid with PTSD in exploratory analyses adjusting for sociodemographic and clinical covariates. Conclusions: Findings highlight the importance of assessing and targeting panic in PTSD/SUD clinics, but suggest panic may not discriminate between specific DUDs that commonly co-occur with PTSD. Study limitations and future directions are discussed.

Longitudinal Associations of Global and Daily Support with Marital Status.

The provision and receipt of emotional support demonstrates benefits for relationships; however, little research has investigated how either global or day-to-day spousal support influences marital stability. This project assessed how global perception of support from a partner and daily provision and receipt of emotional support over 1 week contributed to divorce 10 years later, accounting for demographic covariates. There were no significant associations of support variables with future divorce. Greater education attainment was the only factor significantly associated with decreased risk for divorce. Results suggest that despite potential short-term benefits, global and daily support may not predict long-term marital stability.

Differences in functional and structural social support among female and male veterans and civilians.

PURPOSE: Social support is an important correlate of health behaviors and outcomes. Studies suggest that veterans have lower social support than civilians, but interpretation is hindered by methodological limitations. Furthermore, little is known about how sex influences veteran-civilian differences. Therefore, we examined veteran-civilian differences in several dimensions of social support and whether differences varied by sex. METHODS: We performed a cross-sectional analysis of the 2012-2013 National Epidemiologic Survey of Alcohol and Related Conditions-III, a nationally representative sample of 34,331 respondents (male veterans = 2569; female veterans = 356). We examined veteran-civilian differences in functional and structural social support using linear regression and variation by sex with interactions. We adjusted for socio-demographics, childhood experiences, and physical and mental health. RESULTS: Compared to civilians, veterans had lower social network diversity scores (difference [diff] = - 0.13, 95% confidence interval [CI] - 0.23, - 0.03). Among women but not men, veterans had smaller social network size (diff = - 2.27, 95% CI - 3.81, - 0.73) than civilians, attributable to differences in religious groups, volunteers, and coworkers. Among men, veterans had lower social network diversity scores than civilians (diff = - 0.13, 95% CI - 0.23, - 0.03); while among women, the difference was similar but did not reach statistical significance (diff = - 0.13, 95% CI - 0.23, 0.09). There was limited evidence of functional social support differences. CONCLUSION: After accounting for factors that influence military entry and social support, veterans reported significantly lower structural social support, which may be attributable to reintegration challenges and geographic mobility. Findings suggest that veterans could benefit from programs to enhance structural social support and improve health outcomes, with female veterans potentially in greatest need.

Social Support Moderates the Association Between Posttraumatic Stress Disorder Treatment Duration and Treatment Outcomes in Telemedicine-Based Treatment Among Rural Veterans.

For patients participating in trauma-focused psychotherapies for posttraumatic stress disorder (PTSD), such as cognitive processing therapy (CPT), pretreatment characteristics may moderate treatment effectiveness. For instance, preexisting supportive relationships may encourage skill utilization or provide contrasts to maladaptive cognitive biases highlighted in trauma-focused treatments for PTSD. Such pretreatment characteristics are important to study in rural individuals, who may experience barriers to initiating and completing treatment. The aim of this study was to examine whether pretreatment social support, measured using the Medical Outcomes Study Social Support Survey, would moderate the association between CPT duration (i.e., number of sessions attended) and change in PTSD symptoms, using data from a pragmatic randomized controlled trial of a telemedicine-based collaborative care intervention for rural veterans (N = 225). Social support moderated the association between CPT duration and PTSD symptom change, B = -0.016, SE = -.006; 95% CI [-0.028, -0.005], such that increased duration was associated with more PTSD symptom change only at average or higher levels of support. This effect was found for overall and emotional support but not tangible support. Additionally, on average, among participants who attended eight or more CPT sessions, only those at or above 1 standard deviation above the mean social support score demonstrated a reliable change in PTSD symptoms. The results indicate that the link between CPT treatment duration and treatment outcomes may be stronger for veterans with higher levels of pretreatment social support.

Supporting a Spouse With Military Posttraumatic Stress: Daily Associations With Partners' Affect.

Service members and veterans (SM/Vs) with posttraumatic stress disorder (PTSD) can receive significant benefits from social support by a spouse or romantic partner. However, little is known about how providing support impacts partners. This study sought to identify (a) how provision of support is associated with partners' daily negative and positive affect and (b) how SM/Vs' PTSD symptom severity might moderate such associations. In a 14-day daily-diary study that assessed 64 couples in which one member was an SM/V with PTSD symptoms, partners reported nightly on whether or not they provided instrumental support and/or emotional support that day as well as their current negative and positive affect. Multilevel modeling showed that the provision of emotional and instrumental support were both significantly related to partners' lower levels of negative affect, f 2 = 0.09, and higher levels of positive affect, f 2 = 0.03, on that same day but not the next day. The positive same-day effects were seen if any support was given, with no additive effects when both types of support were provided. Severity of SM/V PTSD moderated the association between provision of emotional support and lower same-day negative affect such that the association was significant only when PTSD symptoms were more severe. Overall, these findings indicate that support provision to a partner with PTSD is associated with improved affect for the romantic partner providing support. However, given that only same-day affect was associated with support, the findings may also suggest that positive affect increases the provision of support.

Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Apoyo a un Cónyuge con Estrés Postraumático Militar: Asociaciones de la vida diaria con el Afecto de las Parejas EL APOYO A UNA ESPOSA CON SÍNTOMAS DE TEPT Los miembros del servicio y los veteranos (SM/Vs en sus siglas en inglés) con Trastorno de Estrés Postraumático (TEPT) pueden recibir significativos beneficios del apoyo social por parte de un cónyuge o pareja romántica. Sin embargo, poco se sabe acerca de cómo el hecho de proporcionar apoyo impacta a las parejas. Este estudio buscó identificar (a) cómo la provisión de apoyo está asociado con el afecto negativo y positivo diario de las parejas y (b) cómo la severidad de los síntomas TEPT de SM/Vs podría moderar tales asociaciones. En un estudio diario de 14 días que evaluó 64 parejas en las que un miembro era un SM/V con síntomas de TEPT, las parejas informaron cada noche sobre si proporcionaron o no apoyo instrumental y/o apoyo emocional ese día, como también informaron sobre su afecto negativo y positivo actual. El modelo multinivel mostró que la provisión del apoyo emocional e instrumental se relacionaron significativamente tanto con los niveles más bajos de afecto negativo, f2 = 0.09, y niveles más altos de afecto positivo, f2 = 0.03, en ese mismo día, pero no el día siguiente. Los efectos positivos del mismo día se observaron si se brindó cualquier tipo de apoyo, sin efectos adicionales cuando se proporcionaron ambos tipos de apoyo. La severidad del TEPT en SM/V moderó la asociación de la provisión de apoyo emocional con un afecto negativo más bajos en el mismo día, de modo que la asociación fue significativa solo cuando los síntomas del TEPT fueron más severos. En general, estos hallazgos indican que proveer apoyo a una pareja con TEPT se asocia con una mejora en los afectos en la pareja romántica que brinda apoyo. Aunque dado que solo el afecto del mismo día fue asociado con apoyo, los hallazgos también pueden sugerir que un afecto positivo incrementa la provisión de apoyo.

Daily Posttraumatic Stress Disorder Symptom Accommodation and Relationship Functioning in Military Couples.

Romantic partners' accommodation of trauma survivors' posttraumatic stress disorder (PTSD) symptoms (e.g., taking on tasks, survivors avoid participating in social withdrawal) is associated with lower relationship satisfaction for both partners and survivors. Little is known about associations of partner accommodation with other aspects of relationship functioning, like intimacy. Sixty-four male military veterans with at least subclinical PTSD and their partners participated in a 2-week daily diary study. Veterans completed nightly measures of PTSD symptoms, while female partners completed nightly measures of accommodating behaviors performed that day. Both partners reported feelings of intimacy each night. Multilevel models revealed that accommodation was significantly, negatively associated with feelings of intimacy, with stronger effects for partners (t = -8.70) than for veterans (t = -5.40), and stronger effects when veterans had lower (t = -7.43) rather than higher (t = -5.20) levels of daily PTSD symptoms. Therapists should consider accommodating behaviors as a potential impediment to relationship intimacy, particularly when veterans have less severe symptoms of PTSD. Accommodating behaviors are an ideal treatment target in behavioral couple therapies.

La adaptación de las parejas románticas a los síntomas del trastorno por estrés postraumático (TEPT) de los sobrevivientes de traumas (p. ej.: hacerse cargo de tareas que los sobrevivientes evitan, participar en el aislamiento social) está asociada con una menor satisfacción con la relación tanto para las parejas como para los sobrevivientes. Se sabe poco acerca de las asociaciones de la adaptación de la pareja con otros aspectos del funcionamiento de la relación, como la intimidad. Sesenta y cuatro militares veteranos con al menos TEPT subclínico y sus parejas participaron en un estudio de registro diario de dos semanas. Los veteranos completaron mediciones nocturnas de los síntomas de TEPT, mientras que las parejas femeninas completaron mediciones nocturas de conductas de adaptación realizadas ese día. Ambas parejas informaron sentimientos de intimidad cada noche. Los modelos multinivel revelaron que la adaptación estuvo asociada considerablemente y negativamente con sentimientos de intimidad, con efectos más fuertes para las parejas (t = −8.70) que para los veternos (t = −5.40), y con efectos más fuertes cuando los veteranos tuvieron niveles más bajos (t = −7.43), en lugar de más altos, (t = −5.20) de síntomas diarios de TEPT. Los terapeutas deben sopesar las conductas de adaptación como un posible impedimento para la intimidad en la relación, particularmente cuando los veteranos tienen síntomas menos graves de TEPT. Las conductas de adaptación son el objetivo ideal del tratamiento en las terapias conductuales de pareja.

Deployment-Related Benefit Finding and Postdeployment Marital Satisfaction in Military Couples.

Extensive research has evaluated potential negative effects of military deployments on romantic relationships. Comparatively few studies have examined potential positive effects of such deployments. In stressful situations, benefit finding (BF) has been found to be linked with better functioning on both individual and interpersonal levels. This study reports on deployment-related BF in a sample of 67 male service members (SMs) who deployed at least once since 9/11/2001 and their wives. Couples completed measures of marital satisfaction at baseline (an average of 1 year postdeployment) and follow-up 4-6 months later. At follow-up, SMs also provided data on symptoms of posttraumatic stress, and both partners provided reports of deployment-related BF. Multivariate path analysis controlling for SMs' PTSD symptom severity revealed that wives' BF was positively associated with increases in SMs' relationship satisfaction. These findings suggest that wives' responses to deployment may be more influential than SMs' responses to deployment on military couples' relationships. This pattern indicates that support for spouses during deployments is essential; furthermore, such support should include an emphasis on trying to facilitate personal growth in spouses.

The role of personality traits and profiles in posttrauma comorbidity.

Many service members experience symptoms of posttraumatic stress disorder (PTSD) after deployment. PTSD can vary widely in its presentation and associated features, such as comorbid conditions. Research has shown that veterans with PTSD and an internalizing personality profile are more likely to experience internalizing comorbidity (e.g., anxiety, depression), whereas veterans with PTSD and an externalizing personality profile are more likely to experience externalizing comorbidity (e.g., substance abuse, aggression). To date, however, this research has been limited by a focus on diagnosable disorders and personality categories. In a nonclinical sample of 224 National Guard/Reserve service members who had served since 2001, we explored whether personality traits (measured continuously) moderated associations of PTSD symptom severity with the severity of internalizing (depression, anxiety) and externalizing (alcohol abuse, aggression) symptoms. Results showed that the association of PTSD with anxiety was stronger when extraversion was lower (corresponding to an internalizing personality profile). Moreover, the association of PTSD with alcohol abuse was stronger when extraversion was high and conscientiousness was low (corresponding to an externalizing personality profile). Surprisingly, this association was also stronger when extraversion was low and conscientiousness was high. Results offer additional insights into prior research on personality and comorbidity.

Gender differences in the associations of PTSD symptom clusters with relationship distress in U.S. Vietnam veterans and their partners.

Research has consistently linked symptoms of posttraumatic stress disorder (PTSD) with relationship distress in combat veterans and their partners. Studies of specific clusters of PTSD symptoms indicate that symptoms of emotional numbing/withdrawal (now referred to as negative alterations in cognition and mood) are more strongly linked with relationship distress than other symptom clusters. These findings, however, are based predominantly on samples of male veterans. Given the increasing numbers of female veterans, research on potential gender differences in these associations is needed. The present study examined gender differences in the multivariate associations of PTSD symptom clusters with relationship distress in 465 opposite-sex couples (375 with male veterans and 90 with female veterans) from the National Vietnam Veterans Readjustment Study. Comparisons of nested path models revealed that emotional numbing/withdrawal symptoms were associated with relationship distress in both types of couples. The strength of this association, however, was stronger for female veterans (b = .46) and female partners (b = .28), compared to male veterans (b = .38) and male partners (b = .26). Results suggest that couples-based interventions (e.g., psychoeducation regarding emotional numbing symptoms as part of PTSD) are particularly important for both female partners of male veterans and female veterans themselves.

The significant others' responses to trauma scale (SORTS): applying factor analysis and item response theory to a measure of PTSD symptom accommodation.

Background: Symptom accommodation by family members (FMs) of individuals with posttraumatic stress disorder (PTSD) includes FMs' participation in patients' avoidance/safety behaviours and constraining self-expression to minimise conflict, potentially maintaining patients' symptoms. The Significant Others' Responses to Trauma Scale (SORTS) is the only existing measure of accommodation in PTSD but has not been rigorously psychometrically tested.Objective: We aimed to conduct further psychometric analyses to determine the factor structure and overall performance of the SORTS. Method: We conducted exploratory and confirmatory factor analyses using a sample of N = 715 FMs (85.7% female, 62.1% White, 86.7% romantic partners of individuals with elevated PTSD symptoms).Results: After dropping cross-loading items, results indicated good fit for a higher-order model of accommodation with two factors: an anger-related accommodation factor encompassed items related largely to minimising conflict, and an anxiety-related accommodation factor encompassed items related primarily to changes to the FM's activities. Accommodation was positively related to PTSD severity and negatively related to relationship satisfaction, although the factors showed somewhat distinct associations. Item Response Theory analyses indicated that the scale provided good information and robust coverage of different accommodation levels.Conclusions: SORTS data should be analysed as both a single score as well as two factors to explore the factors' potential differential performance across treatment and relationship outcomes.

We examined the Significant Others' Responses to Trauma Scale (SORTS), a measure of symptom accommodation in PTSD, among a large sample of family members.As measured by the SORTS, accommodation in PTSD could be broken down into two aspects: anger-related accommodation and anxiety-related accommodation.Accommodation was positively related to PTSD severity and negatively related to relationship satisfaction.

Mechanisms of the association between PTSD and sexual arousal and lubrication functioning among trauma-exposed female service members/veterans.

BACKGROUND: The presence of a post-traumatic stress disorder (PTSD) diagnosis or higher PTSD severity is associated with higher overall sexual dysfunction in female service members/veterans. However, the mechanisms linking PTSD to specific components of women's sexual arousal function, like lubrication and mental arousal, are unknown. METHODS: We conducted a survey among 464 women who reported probable Criterion A exposure for PTSD. Path analysis examined (1) the association of PTSD with sexual arousal, (2) whether specific PTSD symptom clusters were uniquely associated with sexual arousal, and (3) whether this association is indirect, through the effects of higher depression severity and lower romantic relationship satisfaction. Arousal was operationalized to measure both mental (subjective arousal) and physical (lubrication) experiences. RESULTS: Higher PTSD severity was associated with lower lubrication and arousal function. The association of PTSD severity with arousal was indirect, through lower romantic relationship satisfaction (estimate: -0.12; 95% CI: [-0.014, -0.007]) and higher depression (estimate: -0.08, 95% CI: [-0.012, -0.002]). The association of PTSD severity with lubrication was also indirect, but only through lower relationship satisfaction (estimate: -0.10, 95% CI: [-0.013, -0.006]). PTSD symptom clusters were not uniquely associated with arousal and lubrication through mediated pathways. LIMITATIONS: Data were from a cross-sectional study using a convenience sample. Criterion A exposure could not be confirmed. CONCLUSIONS: PTSD may lead to arousal and lubrication dysfunction by contributing to higher depression severity and strained romantic relationships. Interventions targeting reductions in depressive symptoms and bolstering relationship satisfaction may minimize the burden of PTSD on sexual arousal concerns.

Table for two: Perceptions of social support from participants in a weight management intervention for veterans with PTSD and overweight or obesity.

Individuals with posttraumatic stress disorder (PTSD) are at an increased risk of being classified as overweight or with obesity in part due to PTSD symptoms (e.g., sleep disturbance and social isolation) interfering with activity and healthy eating. MOVE!+UP is a 16-week behavioral weight management program, tailored to address such barriers for people with PTSD, by combining evidence-based weight loss education and support with cognitive behavior therapy skills to reduce PTSD symptom-based weight management barriers. This qualitative study examined veterans' (n = 37) perceptions of social support relevant to weight management, health behaviors, and mental health while participating in an uncontrolled pilot of MOVE!+UP. Template analysis of transcripts from 1-hr semistructured qualitative interviews identified four main categories of participant responses. Participants described positive aspects, particularly cohesiveness around a shared veteran identity, feeling less alone, accountability, and having others eat healthier and exercise with them. Conversely, relationship-based barriers included other participants' poor MOVE!+UP group session attendance and engagement, and loved ones' encouragement of making unhealthy choices. Many described having limited relationships or trouble accessing available support. Finally, PTSD symptoms were a significant barrier to utilizing social support to facilitate weight loss. Findings suggest future behavioral weight management programs should recruit members with similar backgrounds to capitalize on shared experience, encourage consistent attendance and meaningful participation, deliver education about how to leverage social support from others outside the program, and address mental health symptoms that impede social support and healthy lifestyles.

Suicide Attempts Among Racial and Ethnic Groups in a Nationally Representative Sample.

OBJECTIVE: Evaluate suicide attempt prevalence and potentially related sociodemographic and psychiatric factors among racial and ethnic groups. METHODS: Between 2012 and 2013, the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III) conducted semi-structured interviews with 36,309 adults in the USA. We identified lifetime suicide attempt prevalence and significant predictors for each racial/ethnic group using stratified logistic regressions. Analyses were exploratory without a priori hypotheses. RESULTS: Asian/Native Hawaiian/other Pacific Islander and Black individuals had the lowest prevalence of suicide attempts while Alaska Native/American Indian and White individuals had the highest prevalence. Identifying as female and meeting criteria for psychiatric diagnoses featuring mood regulation difficulties (depression, borderline personality disorder, bipolar I disorder) were consistently related to a suicide attempt history across racial and ethnic groups, whereas substance abuse disorders and other sociodemographic factors differed between racial and ethnic groups in their associations with suicide attempt history. CONCLUSIONS: Although several factors were consistently related to suicide risk across racial and ethnic groups, the prevalence of suicide attempts and overall pattern of related factors were not uniform between racial and ethnic groups. POLICY IMPLICATIONS: Study findings highlight the importance of considering suicide risk within the context of race and ethnicity both regarding the overall prevalence of risk and in determining personal factors associated with elevated risk. A failure to appreciate experiences related to race and ethnicity may adversely impact suicide risk assessment and treatment, ultimately contributing to health disparities. Results suggest that additional research is warranted.

Identifying PTSD symptom typologies: A latent class analysis.

Posttraumatic stress disorder (PTSD) is characterized by re-experiencing, avoidance, negative alterations in cognition and mood, and arousal symptoms per the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). While numerous symptom combinations are possible to meet diagnostic criteria, simplification of this heterogeneity of symptom presentations may have clinical utility. In a nationally representative sample of American adults with lifetime DSM-5 PTSD diagnoses from the third wave of the National Epidemiologic Survey on Alcohol and Related Conditions (n = 2,365), we used Latent Class Analysis (LCA) to identify qualitatively distinct PTSD symptom typologies. Subsequently, we used linear and logistic regressions to identify demographic, trauma-related, and psychiatric characteristics associated with membership in each class. In contrast to prior LCAs with DSM-IV-TR diagnostic criteria, fit indices for the present analyses of DSM-5 PTSD revealed a four-class solution to the data: Dysphoric (23.8%), Threat-Reactivity (26.1%), High Symptom (33.7%), and Low Symptom (16.3%). Exploratory analyses revealed distinctions between classes in socioeconomic impairment, trauma exposure, comorbid diagnoses, and demographic characteristics. Although the study is limited by its cross-sectional design (preventing analysis of temporal associations or causal pathways between covariates and latent classes), findings may support efforts to develop personalized medicine approaches to PTSD diagnosis and treatment.

Change in social support while participating in behavioral activation for PTSD.

OBJECTIVE: Lack of social support predicts the development, maintenance, and exacerbation of posttraumatic stress disorder (PTSD). Moreover, social dysfunction is associated with recurrent episodes of PTSD care, and detachment/estrangement from others is a strong predictor of suicidal ideation among those with PTSD. Thus, treatments to improve social functioning among those with PTSD are needed. METHOD: Eighty veterans of recent operations in Iraq and Afghanistan participated in a randomized controlled trial comparing treatment as usual to behavioral activation (BA) for PTSD, a treatment that focuses on reducing avoidance behaviors and increasing engagement in valued goals rather than explicitly confronting trauma memories. RESULTS: Mixed-model regression analyses revealed that, accounting for gender, baseline PTSD, and marital status, participants who received BA experienced greater improvements in the number of social supports from baseline to posttreatment compared with those in treatment as usual (F1,96 = 6.29, p = .014). Gains were not maintained at 3-month follow-up, and significant results were not found for satisfaction with social supports. CONCLUSIONS: BA may facilitate an increase in the perceived number of social supports available to veterans with PTSD, but treatment adaptation may be necessary to maintain these gains and to increase satisfaction with social support.
