Evaluation of the critical warzone experiences scale among Gulf War I-era veterans: Associations with PTSD symptoms, depressive symptoms, and suicidal thoughts and behaviors.

Prior research has established the psychometric properties of the Critical Warzone Experiences (CWE) scale among post-9/11 Iraq/Afghanistan-era veterans; however, the psychometric properties of the CWE among Gulf War I-era veterans have not yet been established. The first objective of the present study was to examine the psychometric properties of the CWE among Gulf War I-era veterans. The second objective was to test the hypothesis that the CWE would have a significant indirect effect on suicidal thoughts and behaviors via posttraumatic stress disorder (PTSD) and depressive symptoms. To test these hypotheses, a survey packet that included the CWE and measures of PTSD symptoms, depressive symptoms, and suicidal thoughts and behaviors was administered to 1,153 Gulf War I-era veterans. Consistent with prior research in post-9/11 Iraq/Afghanistan-era veterans, the CWE exhibited good internal consistency (α = .85), a unidimensional factor structure (RMSEA = .056, CFI = .959, SRMR = .033; average factor loading = .69), and good concurrent validity with PTSD (r = .47, p < .001) and depressive (r = .31, p < .001) symptoms among Gulf War I-era veterans. Additionally, as hypothesized, a significant indirect effect from the CWE to suicidal thoughts and behaviors via PTSD and depressive symptoms (ß = .35, p < .001) was also observed. Taken together, our findings provide strong support for using the CWE with Gulf War I-era veterans.

Factors Associated with High-Risk Substance Use in Persons Receiving Psychiatric Treatment for a Primary Trauma- and Stressor-Related Disorder Diagnosis.

OBJECTIVE: Although mental health disorders and high-risk substance use frequently co-occur, they are typically investigated independently. Clinical trials focused on treatment for individuals with trauma- and stressor-related disorders often exclude individuals with high-risk substance use. Little is also known about the role of gender in the relationship between trauma- and stressor-related disorders and high-risk substance use. We examined the relationship between trauma- and stressor-related disorders, high-risk substance use, and gender. METHODS: Using the Mental Health Client-Level Data dataset, we examined 15,772 adults receiving treatment in psychiatric hospitals in the United States from 2013 to 2019. RESULTS: A logistic regression model showed that for men, relative to women, having multiple mental health diagnoses and having a serious mental illness or serious emotional disturbance was associated with greater odds of high-risk substance use. CONCLUSIONS: This study underscores the value of comprehensive gender-centered treatment for people with trauma- and stressor-related disorders engaging in high-risk substance use.

Cannabis use and suicide risk among Gulf War veterans.

Cannabis use has been indicated as a risk factor for suicide in veterans. This study of Gulf War veterans tested the relationship between self-report past year cannabis use and (a) past year suicidal ideation and (b) risk for suicidal behavior. Data were from a national sample (N = 1126) of Gulf War veterans. Logistic regression models indicated cannabis use was associated with past year suicidal ideation and elevated risk for suicidal behavior, independent of key covariates. In corroboration with research on other military populations, this study indicates a potentially concerning association between cannabis use and suicide risk in Gulf War veterans.

Effects of Alcohol Reduction Interventions on Blood Pressure.

PURPOSE OF REVIEW: Much of alcohol's purported negative impact on a population's health can be attributed to its association with increased blood pressure, rates of hypertension, and incidence of cardiovascular disease (CVD). Less attention, however, has been placed on the association of the positive impact of alcohol reduction interventions on physical health. RECENT FINDINGS: This review delineates the evidence of blood pressure reductions as a function of alcohol reduction interventions based on current care models. The findings of this review suggest two things: (1) sufficient evidence exists for a relationship between alcohol reductions and blood pressure generally, and (2) little evidence exists for the relationship between alcohol reductions and blood pressure for any one care model currently employed in the health system. The evidence base would benefit from more studies using established alcohol reduction interventions examining the impact of these interventions on blood pressure.

Correlates and clinical associations of military sexual assault in Gulf War era U.S. veterans: Findings from a national sample.

Military sexual assault (MSA) is a prevalent issue among military personnel that can have direct implications on postmilitary mental health. Gulf War era U.S. veterans represent the first cohort in which women veterans were integrated into most aspects of military service except for combat. The present study sought to build on prior studies by identifying characteristics associated with the occurrence of MSA and clinical correlates of MSA and examining how these differ between men and women. This study analyzed cross-sectional survey data from a national sample of treatment-seeking Gulf War era veterans. Participants (N = 1,153) reported demographic information, clinical outcomes, military background, and history of MSA. MSA was more common among female veterans (n = 100, 41.3%) than male veterans (n = 32, 3.6%). The odds of experiencing MSA were approximately 19 times higher for female veterans relative to their male peers, OR = 18.92, p < .001. Moreover, as expected, MSA was robustly associated with probable current posttraumatic stress disorder, probable current depression, and past-year suicidal ideation in female veterans, whereas combat exposure was robustly associated with these sequelae in male veterans. The present findings confirm that a large proportion of female veterans from the Gulf War era experienced MSA and highlight the deleterious correlates of MSA on veterans' mental health. Sex differences of correlates of MSA and subsequent clinical associations are highlighted.

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.

Criminal legal involvement among recently separated veterans: Findings from the LIMBIC study.

OBJECTIVE: This study investigated individual-level and neighborhood-level predictors of criminal legal involvement of veterans during the critical transition period from military to civilian life. HYPOTHESES: We hypothesized that substance use, mental health, and personality disorders will increase the incidence of criminal legal involvement, which will be highest among veterans living in socioeconomically disadvantaged neighborhoods after military discharge. METHOD: We analyzed data from a longitudinal cohort study of 418,624 veterans who entered Department of Veterans Affairs (VA) health care after leaving the military. Department of Defense (DoD) data on clinical diagnoses, demographics, and military history were linked to VA data on neighborhood of residence and criminal legal involvement. RESULTS: Criminal legal involvement in the 2 years following military discharge was most strongly predicted by younger age, substance use disorder, and being male. Other predictors included the military branch in which veterans served, deployment history, traumatic brain injury, serious mental illness, personality disorder, having fewer physical health conditions, and living in socioeconomically disadvantaged neighborhoods. These factors combined in multivariable analysis yielded a very large effect size for predicting criminal legal involvement after military separation (area under the curve = .82). The incidence of criminal legal involvement was 10 times higher among veterans with co-occurring substance use disorder, serious mental illness, and personality disorder than among veterans with none of these diagnoses, and these rates were highest among veterans residing in more socioeconomically disadvantaged neighborhoods. CONCLUSIONS: To our knowledge, this is the largest longitudinal study of risk factors for criminal legal involvement in veterans following military discharge. The findings supported the hypothesis that veterans with co-occurring mental disorders living in socioeconomically disadvantaged neighborhoods were at higher risk of criminal legal involvement, underscoring the complex interplay of individual-level and neighborhood-level risk factors for criminal legal involvement after veterans leave the military. These results can inform policy and programs, such as the DoD Transition Assistance Program (TAP) and the VA Military to Civilian Readiness Pathway program (M2C Ready), to enhance community reintegration and prevent criminal legal involvement among veterans transitioning from military to civilian life.

Disentangling the Longitudinal Relationship between Loneliness and Depressive Symptoms in U.S. Adults Over 50.

OBJECTIVES: A seminal study on loneliness and depression suggested that loneliness influences depression more than the reverse. However, the study's analytic method has since been criticized for failing to account for the trait-like nature of variables. This study aimed to examine the longitudinal relationship between loneliness and depressive symptoms while accounting for the trait-like nature of both variables. METHODS: Data (n = 16,478) came from the Health and Retirement Study (2006-2016). Measures included the Hughes Loneliness Scale and a modified Center for Epidemiologic Studies Depression scale (loneliness item omitted). Analyses consisted of random intercepts cross-lagged panel models (three time-points evenly spaced across eight years). RESULTS: There was evidence that loneliness and depressive symptoms are trait-like and these trait-like components are strongly associated. There was not evidence of cross-lagged effects between loneliness and depressive symptoms. CONCLUSIONS: A tendency toward loneliness corresponded with a tendency toward depressive symptoms. However, deviations in one's typical level of loneliness did not predict deviations in one's typical level of depressive symptoms or vice-versa. These findings do not support past assertions that loneliness shapes subsequent depression more than the reverse. CLINICAL IMPLICATIONS: By middle to late adulthood, loneliness and depressive symptoms are trait-like phenomena that are strongly associated.

Suicidal ideation and thoughts of self-harm during the COVID-19 pandemic: The role of COVID-19-related stress, social isolation, and financial strain.

BACKGROUND: There are significant concerns about mental health problems occurring due to the coronavirus disease 2019 (COVID-19) pandemic. To date, there has been limited empirical investigation about thoughts of suicide and self-harm during the COVID-19 pandemic. METHODS: A national survey was conducted May 2020 to investigate the association between mental health symptoms, social isolation, and financial stressors during the COVID-19 pandemic and thoughts of suicide and self-harm. A total of 6607 US adults completed an online survey; survey criteria included an age minimum of 22 years old and reported annual gross income of $75,000 or below. Statistical raking procedures were conducted to more precisely weight the sample using US Census data on age, geographic region, sex, race, and ethnicity. RESULTS: COVID-19-related stress symptoms, loneliness, and financial strain were associated with thoughts of suicide/self-harm in multivariable logistic regression analyses, as were younger age, being a military veteran, past homelessness, lifetime severe mental illness, current depressive symptoms, alcohol misuse, and having tested positive for COVID-19. Greater social support was inversely related to thoughts of suicide/self-harm whereas running out of money for basic needs (e.g., food), housing instability (e.g., delaying rent), and filing for unemployment or disability were positively related. CONCLUSIONS: Public health interventions to decrease risk of suicide and self-harm in the wake of the COVID-19 pandemic should address pandemic-related stress, social isolation, and financial strain experienced including food insecurity, job loss, and risk of eviction/homelessness.

Drinking to Cope with Posttraumatic Stress: A Nationally Representative Study of Men with and without Military Combat Experience.

OBJECTIVE: Posttraumatic stress disorder (PTSD) and hazardous alcohol use are prevalent among trauma survivors. Despite higher rates of both PTSD and hazardous alcohol use among military combat veterans than civilians, scant research has examined whether military combat experience is associated with drinking alcohol to cope with PTSD symptoms. This study tested the hypothesis that compared to trauma-exposed men without combat experience, men with military combat experience would be more likely to endorse drinking alcohol to cope with their PTSD symptoms. Methods: Interview data from N = 11,474 men who reported at least one lifetime traumatic experience were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a face-to-face interview study that recruited a nationally representative sample of adults living in the United States between 2004 and 2005. Results: Among men endorsing lifetime trauma exposure, men with military combat experience (n = 1,386) were more likely than men without combat experience (n = 10,088) to report drinking alcohol to cope (7.22 vs. 2.61% in unweighted analyses, 6.46 vs. 2.37% in weighted analyses). Total number of lifetime trauma types, lifetime PTSD severity, and lifetime alcohol abuse/dependence were significantly associated with drinking to cope in bivariate and multivariate analyses. Military combat experience was significantly associated with drinking to cope in multivariate analyses adjusting for lifetime PTSD diagnosis. Military combat experience was not significantly associated with drinking to cope in multivariate analyses adjusting for lifetime PTSD symptom count. Conclusions: Although military combat experience was significantly associated with drinking to cope in bivariate analyses, multivariate analyses yielded mixed findings: combat experience was significantly associated with drinking to cope in models adjusting for PTSD diagnosis, but not in models adjusting for PTSD symptom count. Findings highlight the importance of assessing and targeting PTSD symptom-related alcohol use, even in the absence of alcohol abuse/dependence. Results from this preliminary study could inform future research on drinking to cope with PTSD symptoms among military combat veterans and other trauma survivors.

Cognitive Rehabilitation With Mobile Technology and Social Support for Veterans With TBI and PTSD: A Randomized Clinical Trial.

OBJECTIVE: To investigate effects of cognitive rehabilitation with mobile technology and social support on veterans with traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD). PARTICIPANTS: There were 112 dyads, comprised by a veteran and a family member or friend (224 participants in total). DESIGN: Dyads were randomized to the following: (1) a novel intervention, Cognitive Applications for Life Management (CALM), involving goal management training plus mobile devices for cueing and training attentional control; or (2) Brain Health Training, involving psychoeducation plus mobile devices to train visual memory. MAIN MEASURES: Executive dysfunction (disinhibition, impulsivity) and emotional dysregulation (anger, maladaptive interpersonal behaviors) collected prior to randomization and following intervention completion at 6 months. RESULTS: The clinical trial yielded negative findings regarding executive dysfunction but positive findings on measures of emotion dysregulation. Veterans randomized to CALM reported a 25% decrease in anger over 6 months compared with 8% reduction in the control (B = -5.27, P = .008). Family/friends reported that veterans randomized to CALM engaged in 26% fewer maladaptive interpersonal behaviors (eg, aggression) over 6 months compared with 6% reduction in the control (B = -2.08, P = .016). An unanticipated result was clinically meaningful change in reduced PTSD symptoms among veterans randomized to CALM (P < .001). CONCLUSION: This preliminary study demonstrated effectiveness of CALM for reducing emotional dysregulation in veterans with TBI and PTSD.

The effects of safety behavior availability versus utilization on inhibitory learning during exposure.

This study re-analyzes data from Sy and colleagues (2011; Behaviour Research and Therapy, 49, 305-314) comparing safety behavior availability (SBA) to safety behavior utilization (SBU) during exposure therapy for claustrophobic concerns. The present investigation assessed differential rates of inhibitory learning (i.e. change in danger expectancy and coping self-efficacy) between SBA and SBU before, during, and after a single-session treatment. Thirty-nine participants with marked claustrophobic fear completed six consecutive 5-minute exposure trials in a claustrophobia chamber. Participants in the SBA condition exhibited more interference with inhibitory learning relative to the SBU condition. Danger expectancy was significantly higher in the SBA group and decreased at a markedly slower rate across exposure trials relative to SBU. Coping self-efficacy was also significantly lower among participants in the SBA condition, although groups demonstrated similar rates of change across trials. Limitations, clinical implications, and future directions are discussed.

Behavioral inhibition and posttrauma symptomatology: Moderating effects of safety behaviors and biological sex.

OBJECTIVES: Behavioral inhibition is a trait-level factor associated with posttraumatic stress. Safety behaviors may impact this link by interfering with anxiety habituation. The current study examined the unique and interactive effects of behavioral inhibition, safety behaviors, and participant sex on posttrauma symptom clusters. METHOD: Participants (N = 131; 75.6% female; M = 19.9 years) completed a trauma history interview and questionnaires assessing behavioral inhibition, safety behavior, and posttrauma symptom severity. RESULTS: Safety behaviors were associated with intrusion (partial correlations [pr] = 0.319), avoidance (pr = 0.274), cognition-mood (pr = 0.274), and arousal-reactivity (pr = 0.538) symptoms (all p ≤ 0.001). An interaction of sex and safety behaviors was noted for avoidance (p = 0.047, pr = -0.159) with a significant relation observed only among women ( p < 0.001, pr = 0.442). Safety behaviors also moderated the link between behavioral inhibition and arousal-reactivity (p = 0.002, pr = 0.272) with inhibition predicting symptoms at high levels of safety behavior (p = 0.024, pr = 0.171). CONCLUSION: Trauma-related safety behaviors are associated with greater posttrauma symptoms and evidence differential effects across individual symptom domains.

Scrupulosity, Religious Affiliation and Symptom Presentation in Obsessive Compulsive Disorder.

BACKGROUND: Scrupulosity is a common yet understudied presentation of obsessive compulsive disorder (OCD) that is characterized by obsessions and compulsions focused on religion. Despite the clinical relevance of scrupulosity to some presentations of OCD, little is known about the association between scrupulosity and symptom severity across religious groups. AIMS: The present study examined the relationship between (a) religious affiliation and OCD symptoms, (b) religious affiliation and scrupulosity, and (c) scrupulosity and OCD symptoms across religious affiliations. METHOD: One-way ANOVAs, Pearson correlations and regression-based moderation analyses were conducted to evaluate these relationships in 180 treatment-seeking adults with OCD who completed measures of scrupulosity and OCD symptom severity. RESULTS: Scrupulosity, but not OCD symptoms in general, differed across religious affiliations. Individuals who identified as Catholic reported the highest level of scrupulosity relative to individuals who identified as Protestant, Jewish or having no religion. Scrupulosity was associated with OCD symptom severity globally and across symptom dimensions, and the magnitude of these relationships differed by religious affiliation. CONCLUSIONS: Findings are discussed in terms of the dimensionality of scrupulosity, need for further assessment instruments, implications for assessment and intervention, and the consideration of religious identity in treatment.

Neuropsychological correlates of self-reported impulsivity and informant-reported maladaptive behaviour among veterans with posttraumatic stress disorder and traumatic brain injury history.

OBJECTIVE: Frontal lobe deficits resulting from traumatic brain injury (TBI) and/or posttraumatic stress disorder (PTSD) have been linked to impulsive behaviour. We sought to examine whether neuropsychological performance predicted self-reported impulsivity and informant-reported maladaptive behaviour. METHOD: We administered the Delis-Kaplan Executive Function System (D-KEFS) to 116 Iraq/Afghanistan-era veterans diagnosed with a history of TBI and PTSD. RESULTS: Poorer performance on D-KEFS Stroop Task (both colour and word, separately) and Trail making (letter sequencing and motor speed) tasks and higher PTSD symptom severity were associated with higher self-reported impulsivity. Trail making letter sequencing performance was negatively associated with informant-reported maladaptive behaviour. Regression analyses revealed PTSD symptom severity and Trail making letter sequencing best predicted self-reported impulsivity, even when accounting for age, sex, and education. Only Trail making letter sequencing predicted informant-reported maladaptive behaviour when accounting for other variables in the model. CONCLUSIONS: Attention and processing speed impairments and PTSD symptom severity appear to be important predictors of impulsivity and problematic behaviour among veterans. Findings have implications for theoretical models of aggression and violence and inform the assessment and treatment of individuals with TBI and PTSD.

Psychological Predictors of Health Anxiety in Response to the Zika Virus.

The threat of a United States (U.S.) Zika virus pandemic during 2015-2016 was associated with public anxiety. Such threats represent opportunities to examine hypotheses about health anxiety. The present study investigated psychological predictors of Zika-related anxiety during the 2015-2016 outbreak. U.S. adults (N = 216) completed a battery of measures assessing Zika-related anxiety as well as psychological variables hypothesized to predict anxious responding to the threat of a domestic Zika outbreak. Contrary to hypotheses, regression analyses indicated that only contamination severity overestimates and greater Zika knowledge significantly predicted Zika-related anxiety. Study limitations and clinical implications are discussed.

The Relative Contributions of Experiential Avoidance and Distress Tolerance to OC Symptoms.

BACKGROUND: Obsessive beliefs account for substantial (but not all) obsessive-compulsive (OC) symptoms. Intolerance of internal experiences (IIE), which encompasses the constructs of experiential avoidance (EA) and distress tolerance (DT), refers to difficulty managing unwanted thoughts, emotions, and other internal states, and might add to current explanatory models. Although IIE appears to be conceptually relevant to obsessive-compulsive (OC) symptoms, scant research has examined this relationship empirically. AIM: The present study examined the relative contributions of EA and DT as predictors of OC symptom dimensions. METHOD: A nonclinical sample (n = 496) completed self-report questionnaires measuring general distress, EA, DT and OC symptom dimensions. RESULTS: All variables of interest were significantly (all ps ≤ .001) correlated with one another, such that higher general distress, higher EA, and lower DT were associated with greater OC symptom severity for all symptom dimensions; however, only EA independently predicted obsessional symptoms, but not other OC symptom dimensions. CONCLUSIONS: One's willingness to endure (i.e. EA), rather than their ability to tolerate (i.e. DT) unpleasant internal experiences best predicts obsessional symptoms (i.e. obsessing) above and beyond general distress. Potential implications for understanding, assessing, and treating OC symptoms are discussed.

Differential posttraumatic stress disorder symptom cluster response to stellate ganglion block: secondary analysis of a randomized controlled trial.

Empirically supported treatments for posttraumatic stress disorder (PTSD) exist, but research suggests these therapies are less effective, acceptable, and feasible to deliver to active duty service members (SMs) compared to civilians. Stellate ganglion block (SGB) procedure, in which a local anesthetic is injected around the cervical sympathetic chain or stellate ganglion to temporarily inhibit sympathetic nervous activity, is gaining popularity as an alternative PTSD treatment in military settings. However, it is unknown whether certain PTSD symptoms are more responsive to SGB than others. The current study involved a secondary analysis of data collected from a previous randomized controlled trial of SGB compared to sham (normal saline) injection (N = 113 SMs). PTSD symptoms were assessed via clinical interview and self-report at baseline and 8 weeks post-SGB or sham. Logistic regression analyses showed that the marked alterations in arousal and reactivity PTSD symptom cluster demonstrated the greatest symptom severity reductions after SGB, relative to sham. The reexperiencing cluster also showed pronounced response to SGB in clinician-rated but not self-reported outcomes. Post-hoc item-level analyses suggested that arousal and reactivity cluster findings were driven by reductions in hypervigilance, concentration difficulties, and sleep disturbance, whereas clinician-rated reexperiencing cluster findings were driven by reductions in physiological reactions to trauma cues, emotional reactions to trauma cues, and intrusions. Our findings align with a burgeoning literature positioning SGB as a potential novel or adjunctive PTSD treatment. Results could guide future hypothesis-driven research on mediators of therapeutic change during SGB for PTSD symptoms in SMs.

Differential symptom weighting in estimating empirical thresholds for underlying PTSD severity: Toward a "platinum" standard for diagnosis?

OBJECTIVE: Symptom counts as the basis for Post-Traumatic Stress Disorder (PTSD) diagnoses in the DSM presume each symptom is equally reflective of underlying disorder severity. However, the "equal weight" assumption fails to fit PTSD symptom data when tested. The present study developed an enhanced PTSD diagnosis based on (a) a conventional PTSD diagnosis from a clinical interview and (b) an empirical classification of full PTSD that reflected the relative clinical weights of each symptom. METHOD: Baseline structured interview data from Project Harmony (N = 2658) was used. An enhanced diagnosis for full PTSD was estimated using an empirical threshold from moderated nonlinear factor analysis (MNLFA) latent PTSD scale scores, in combination with a full conventional PTSD diagnosis based on interview data. RESULTS: One in 4 patients in the sample had a PTSD diagnosis that was inconsistent with their empirical PTSD grouping, such that the enhanced diagnostic standard reduced the diagnostic discrepancy rate by 20%. Veterans, and in particular female Veterans, were at greatest odds for discrepancy between their underlying PTSD severity and DSM diagnosis. CONCLUSION: Psychometric methodologies that differentially weight symptoms can complement DSM criteria and may serve as a platform for symptom prioritization for diagnoses in future editions of DSM.

Experiential Avoidance, Posttraumatic Stress Disorder, and Self-Injurious Thoughts and Behaviors: A Moderation Analysis in a National Veteran Sample.

Experiential avoidance (EA) is associated with posttraumatic stress disorder (PTSD) and self-injurious thoughts and behaviors (SITBs) across different populations, and extant literature has demonstrated a strong relationship between PTSD and SITBs. However, no study has explored the potential moderating role EA plays in the association of PTSD with nonsuicidal self-injury (NSSI), suicidal ideation, and suicide attempts. The objective of the present study was to determine if EA would moderate the association with PTSD and SITBs such that the association between PTSD and individuals SITBs would be stronger among individuals with higher EA. In a large national sample of Gulf War Era veterans (N = 1,138), EA was associated with PTSD, lifetime and past-year NSSI, current suicidal ideation, and lifetime suicide attempts in bivariate analyses. Multivariate analyses detected a significant EA by PTSD interaction on lifetime NSSI (AOR = 0.96), past-year NSSI (AOR = 1.03), and suicide attempts (AOR =1.03). Probing of the interactions revealed that the respective associations between PTSD, lifetime and past-year NSSI, and suicide attempts were stronger at lower levels of EA (i.e., better), counter to our hypotheses. These preliminary findings contextualize the relationship between these variables in a Gulf War veterans sample and signal the need to further investigate these relationships. Further, these findings highlight the need for advancement in assessment and intervention of EA and SITBs.
