RESUMO
OBJECTIVE: Alcohol-related problems (e.g., physical, interpersonal, intrapersonal, impulse control, social responsibility) can have an impact on posttraumatic stress disorder (PTSD) symptoms during treatment. Evidence-based online self-help tools exist to target alcohol use and related problems and co-occurring PTSD symptoms. It is unknown to what degree individuals with varying alcohol-related problems respond differently to web-based interventions for hazardous alcohol use and PTSD. The current study evaluated specific alcohol-related problems as potential moderators of PTSD symptom changes during the VetChange online intervention while controlling for average daily alcohol use, gender, race, and age. METHOD: We conducted a secondary analysis of a randomized controlled trial that included 600 post-9/11 veterans (518 men and 82 women). Mixed-effects regression models of alcohol-related problems on PTSD severity scores over time were performed separately in an initial intervention group (IIG; n = 404) and a delayed intervention group (DIG; n = 196) that was used as a comparison condition. RESULTS: Interpersonal problems emerged as a moderator of PTSD symptom changes in IIG such that veterans endorsing greater interpersonal problems demonstrated larger reductions in PTSD symptoms throughout VetChange. There were no significant moderation effects in DIG. Non-White veterans reported significantly higher PTSD symptoms during VetChange. Post hoc analyses indicated that veterans with higher interpersonal problems were more likely to engage in online intervention content focused on identifying high-risk drinking situations and coping with symptoms. CONCLUSIONS: Findings imply that veterans reporting alcohol-related interpersonal problems may benefit the most from, and be more motivated to use, online interventions for hazardous alcohol use and PTSD symptoms.

Importance: Evidence-based treatments for posttraumatic stress disorder (PTSD) exist, but all require 8 to 15 sessions and thus are less likely to be completed than brief treatments. Written exposure therapy (WET) is a brief and efficacious treatment that has not been directly compared with prolonged exposure therapy (PE), a more time-intensive, exposure-based treatment. Objective: To determine whether WET is noninferior to PE in treating PTSD among veterans. Design, Setting, and Participants: A randomized noninferiority clinical trial was conducted between September 9, 2019, and April 30, 2022. Participants were 178 veterans with PTSD presenting to 1 of 3 Veterans Affairs medical centers. Inclusion criteria consisted of a primary diagnosis of PTSD and stable medication. Exclusion criteria included current psychotherapy for PTSD, high suicide risk, active psychosis, unstable bipolar disorder, and severe cognitive impairment. Independent evaluations were conducted at baseline and 10, 20, and 30 weeks after the first treatment session. Data were analyzed from January 1 to March 31, 2023. Interventions: Participants assigned to WET (n = 88) received five to seven 45- to 60-minute sessions. Participants assigned to PE (n = 90) received eight to fifteen 90-minute sessions. The WET sessions included 30 minutes of writing-based imaginal exposure conducted in session, whereas PE sessions included 40 minutes of in-session imaginal exposure and between-session in vivo exposures. Main Outcomes and Measures: The primary outcome was change in PTSD symptom severity measured with the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) from baseline to the 20-week assessment; noninferiority was defined as a less than 10-point difference between the 2 treatment groups. Difference in treatment dropout was also examined. Results: Of the 178 participants, 134 (75.3%) were men, and the mean (SD) age was 44.97 (13.66) years. In terms of race, 37 participants (20.8%) were Black, 112 (62.9%) were White, 11 (6.2%) were more than 1 race, and 18 (10.1%) were of other race (including American Indian or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander [some participants did not specify their race when selecting the category "other"]); in terms of ethnicity, 19 participants (10.7%) were Hispanic. Changes in PTSD symptom severity from baseline to all subsequent assessments among individuals randomized to WET were noninferior relative to individuals randomized to PE. The largest difference between treatments was observed at 10 weeks and was in favor of WET (mean difference, 2.42 [95% CI, 0.35-1.46] points). Participants were significantly less likely to drop out of WET compared with PE (11 [12.5%] vs 32 [35.6%]; χ2 = 12.91; Cramer V = 0.27). Conclusions and Relevance: In this study, WET was noninferior to PE in PTSD symptom change and was associated with significantly less attrition. Findings suggest that WET may transcend previously observed barriers to PTSD treatment for both patients and clinicians. Trial Registration: ClinicalTrials.gov Identifier: NCT03962504.

Better understanding of reasons for and against change may be an effective strategy for supporting drinking reduction or abstinence among Iraq and Afghanistan veterans. The current study explored connections between reasons for and against changing hazardous alcohol use, as well as the relative importance of a given reason. Data from 366 veterans (86% male, 77% White) between the ages of 21 and 56 (M = 31.8, SD = 7.3) were obtained from a nationwide web-based alcohol and posttraumatic stress disorder randomized clinical trial. Participant-generated reasons for and against change were used to estimate two separate network models. The network of motives for changing alcohol use was generally well connected with predominately positive associations. Veterans reporting motivation to change alcohol use to improve functioning, enhance self-worth, and decrease alcohol-related consequences tended to have higher than average motivation to reduce or abstain from alcohol use. Alternatively, the network structure of motives against changing alcohol use demonstrated a nearly equal number of positive and negative associations. Whereas reasons to cope and sleep may imply higher than average motivation to continue drinking the same, veterans reporting reasons to reduce anxiety and have fun tended to have lower than average motivation to continue drinking. The current study may inform content modifications to self-help tools to more quickly and effectively target users' motivations from the beginning. Capitalizing on intervention users' motivations early may promote sustained engagement or improve therapeutic impact among those who only use the intervention for a short period of time.

OBJECTIVE: Rates of hazardous alcohol consumption and co-occurring posttraumatic stress disorder (PTSD) are high among returning combat veterans and may adversely affect satisfaction with life (SWL). Improving life satisfaction represents a potential secondary outcome of web-based interventions for alcohol use and PTSD. Understanding the relationship between intervention targets and SWL may help inform future interventions and provide clarity regarding how improvements are manifesting. We examined returning veterans enrolled in VetChange, an evidence-based web intervention for co-occurring alcohol use and PTSD, to determine changes in SWL over time and as a function of changes in alcohol consumption and PTSD symptoms. METHOD: Participants included 222 returning veterans who reported hazardous drinking. Veterans engaged in a nationwide implementation of VetChange and completed measures of average weekly drinks (AWD), PTSD symptoms, and SWL at baseline, 1, 3, and 6 months. We investigated the effects of changes in PTSD and AWD between baseline and 1 month on SWL over 6 months using linear mixed-effects modeling. RESULTS: Across all veterans, SWL increased by 19% over 6 months. AWD and PTSD decreased between baseline and 1 month, but only change in PTSD predicted changes in SWL over the 6-month interval. CONCLUSIONS: Reductions in PTSD symptoms within the first month of intervention use, and not reductions in drinking, predicted increased SWL over 6 months. SWL is an important marker for recovery and related quality of life, and an important assessment and intervention target of web-based interventions. Interventions may also target SWL, as improvements in SWL promote future recovery and sustained improvement. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
RESUMO
BACKGROUND: The unified protocol (UP) is a promising transdisgnostic treatment for emotional disorders; limited data exists with trauma-exposed populations. This study compared effectiveness of the UP, presented centered therapy (PCT), and treatment as usual (TAU) in trauma-exposed veterans presenting to routine care. METHOD: Trauma-exposed veterans with one or more emotional disorder diagnoses participated in a pilot hybrid-1 effectiveness/preimplementation study. Thirty-seven male and female veterans were randomized to one of three conditions. RESULTS: Multilevel growth curve modeling demonstrated improvement over time across conditions with large effect sizes (range: -2.15 to -3.32), with the UP demonstrating the greatest change. The between group effect sizes for reductions in number of comorbid diagnoses were medium to small and statistically significant (TAU and UP, d = 0.49, p = .056; TAU and PCT d = 0.18, p = .166, UP and PCT d = 0.31, p = .229). Only the UP led to a decrease in the number of comorbid diagnoses (d = -0.71). Psychosocial functioning varied by group, with slight increases in impairment in PCT and TAU, and medium effect size reduction in the UP. Only the UP exhibited significant decreases in self-reported anxiety and depression. Between group differences for UP and PCT were medium to large and statistically significant for depression across two measures (d = -0.72 to d = -1.40). CONCLUSIONS: This represents the first trial examining effectiveness of the UP, PCT, and TAU in trauma-exposed veterans. Despite a small sample, large effect size differences demonstrated promising advantages for the UP. Trial Registration Number: NCT02944994.

OBJECTIVE: Proportionally more women use online alcohol interventions but also report less robust treatment outcomes compared to men. Less is known about outcome disparities among veteran women, who are a growing demographic nationally. The current study examined gender differences among returning veteran men and women who used VetChange, a web-based intervention for hazardous drinking and posttraumatic stress symptoms (PTSS). METHOD: Using data from a nationwide implementation study of returning combat veterans (n = 222), we performed hierarchical linear modeling to examine gender differences in alcohol and PTSS outcomes over six months following VetChange registration. Additional analyses examined gender differences in proportional changes in hazardous drinking and at each assessment point. RESULTS: Returning veterans reported significant decreases in alcohol use and PTSS over time, yet men evidenced significantly greater reduction in average weekly drinks and drinks per drinking day compared to women. Follow up analyses indicated that women were significantly less likely than men to achieve low-risk drinking by one month post-registration. Proportional change in alcohol use yielded marginal and non-significant trends that were, nonetheless, consistent with the overall pattern of gender differences. CONCLUSION: These results contribute to emerging literature suggesting that women use online alcohol use interventions at proportionately higher rates than do men, but do not reduce their drinking as much as men. There are a number of potential content changes that could improve outcomes for returning veteran women using online interventions, and data-driven adaptations based on stakeholder input are recommended.

BACKGROUND: Evidence-based web and mobile interventions are available for a range of mental health concerns. Little is known about how self-administered web interventions are used outside of controlled research trials, and there is a critical need to empirically examine real-world public implementation of such programs. To this end, the aim of the current study was to evaluate and describe outcomes of a nationwide public implementation of VetChange, a self-administered web intervention for veterans with problematic alcohol use and symptoms of PTSD. METHOD: The study used the RE-AIM framework to organize outcomes along five key dimensions: reach, effectiveness, adoption, implementation, and maintenance. This naturalistic observation study included program use information for all who registered an account with VetChange during the 2-year study period and who self-identified as a returning veteran. We collected program use data automatically via normal website operation; a subset of program users provided additional self-report outcome data. The study used linear multilevel mixed modeling to evaluate changes in alcohol use and PTSD symptoms over a six-month postregistration period. RESULTS: VetChange successfully reached a large, geographically diverse sample of returning veterans with risky drinking and PTSD symptoms. Despite variable, overall modest, rates of intervention use over time, registered users demonstrated significant improvements in drinking, PTSD, and quality of life, and participants maintained these outcomes at a six-month follow-up. CONCLUSIONS: Given the observed low cost per acquisition, positive clinical outcomes, and the potential to produce long-term cost savings through reduced health care burden associated with chronic alcohol use disorder and PTSD, this study demonstrates how web-based interventions can provide public health benefits and reduce long-term health care costs.

OBJECTIVE: Veterans of Iraq and Afghanistan conflicts report high rates of drinking, PTSD, and low rates of treatment engagement. Web interventions may help address unmet treatment need; unfortunately, little is known regarding outcomes or adherence to these interventions. In this study, we examined VetChange treatment outcomes and downstream effects of alcohol reduction on PTSD symptoms and intervention dropout rates over six months. METHOD: Participants included 222 veterans (77.5% men, 78.3% White) between 22 and 57 (mean ageâ¯=â¯36.02, SDâ¯=â¯7.19). All VetChange users completed a brief alcohol assessment and received personal feedback, then received full access to intervention content including psychoeducation; motivational and cognitive-behavioral modules for relapse prevention, goal-setting, social support, stress, anger, and sleep management; and mood and drink tracking. Veterans completed self-report measures of alcohol use and PTSD symptoms at baseline, one, three, and six months. RESULTS: Alcohol use dropped by 43% over six months, pâ¯<â¯.001, with the largest decrease occurring within the first month. Greater alcohol reduction in the first month predicted higher subsequent PTSD hyperarousal severity. Over half (52.3%) dropped out by month one, followed by 12.2% and 37.6% by months three and six. Hyperarousal symptoms, hypervigilance specifically, but not alcohol use predicted subsequent intervention dropout. CONCLUSION: These results highlight the importance of attending to the association between alcohol use and PTSD symptom change in web-based interventions for veterans. The fact that hyperarousal symptoms were associated with elevated risk for intervention dropout signifies the need for online intervention refinement aimed at tailoring content to time-varying symptom presentations.

Despite high levels of traffic-related mortality, injury, and impairment among former service members, measures validated to assess problematic driving in this population remain limited. The current study examined characteristics of the Driving Behavior Survey (DBS) in male veterans (76.3% White; age: Mâ¯=â¯56.4, SDâ¯=â¯12.3) meeting criteria for PTSD. Confirmatory factor analyses indicated acceptable fit of a 3-factor model specifying dimensions of anxiety-based performance deficits, exaggerated safety/caution, and hostile/aggressive driving behavior. Concurrent associations with indices of anxiety, depression, trauma history, and clinician-rated PTSD were consistent with small (râ¯=â¯.10-.29) to medium (r = .30-.49) effects. Discriminative validity was noted through elevations in performance deficit (dâ¯=â¯.26), safety/caution (dâ¯=â¯.50), and hostile/aggressive (dâ¯=â¯.39) scales relative to published data from student drivers. Scores comparable to civilian motorists with accident-related PTSD help to qualify the severity of problematic driving behavior in trauma-exposed veterans.

OBJECTIVE: Examine initial levels and pattern of change of alliance in group treatment for posttraumatic stress disorder (PTSD) for veterans. METHOD: One hundred and seventy-eight male veterans with PTSD were recruited for this study. Participants were randomly assigned to either group cognitive behavioral therapy (GCBT) or to group present-centered therapy (GPCT). Alliance with fellow group members was assessed every other session throughout the group (total of seven assessments). Hierarchical linear modeling was used to determine whether treatment condition or index trauma type (interpersonal or non-interpersonal) impacted initial levels of alliance or change in alliance over time. RESULTS: Alliance increased significantly throughout treatment in both conditions. The presence of an interpersonal index event, compared to a non-interpersonal index event, did not significantly impact either initial levels of alliance or change in alliance over time. Participants in the GCBT condition experienced significantly greater growth in alliance over time compared to those in the GPCT condition (p > .05), but did not have significantly different initial alliance ratings. CONCLUSIONS: The components and focus of the GCBT treatment may have facilitated more rapid bonding among members. Interpersonal traumatic experience did not negatively impact group alliance.
RESUMO
OBJECTIVE: Eating disorder (ED) symptoms have gone mostly unexamined among veterans. The current study assessed rates of bulimia nervosa (BN) and binge eating disorder (BED) symptoms and diagnoses and their associations with common comorbidities among male and female veterans. METHOD: Participants were US military veterans who screened positive for trauma histories and/or a probable Diagnostic and Statistical Manual of Mental Disorders 4th Edition (DSM-IV) posttraumatic stress disorder (PTSD) diagnosis (n=499). Symptoms of PTSD were assessed using the Clinician-Administered PTSD Scale, and symptoms of EDs, mood, and substance use disorders were assessed using the Structured Clinical Interview for the DSM-IV. RESULTS: Lifetime rates of BN and BED diagnoses were comparable to civilian populations, and a considerable range of lifetime and current BN and BED symptoms were identified. In multivariate models, PTSD and depression severity were most consistently associated with BN and BED symptom severity, with depression most strongly associated with EDs for women. CONCLUSIONS: Findings highlight the importance of screening for ED symptoms among male and female veterans, particularly those that present with PTSD and depression symptomatology. Future examinations of the temporal order of such relationships and the degree to which ED symptoms and associated symptoms impact veteran functioning are warranted.

Numerous treatments are available that address the core symptoms of posttraumatic stress disorder (PTSD). However, there are a number of related behavioral stress responses that are not assessed with PTSD measures, yet these behavioral stress responses affect quality of life. The goal of the current study was to investigate whether a recently developed measure of behavioral stress response, the Driving Behavior Survey (DBS), was sensitive to change associated with treatment among a group of participants diagnosed with PTSD. The DBS indexes anxious driving behavior, which is frequently observed among individuals with motor vehicle accident-related PTSD. Participants (n = 40) were racially diverse adults (M age = 40.78, 63% women) who met diagnostic criteria for motor vehicle accident-related PTSD. Hierarchical linear modeling analyses indicated that participants who were assigned to a brief, exposure-based intervention displayed significant reductions on the DBS subscales relative to participants assigned to the wait-list control condition (r = .41.43). Moreover, mediational analyses indicated that the observed reductions on the DBS subscales were not better accounted for by reductions in PTSD. Taken together, these findings suggest that the DBS subscales are sensitive to changes associated with PTSD treatment and can be used to augment outcome assessment in PTSD treatment trials.

The Veterans Health Administration (VHA) has promoted the use of telehealth technologies to deliver mental health care to veterans with limited access to services on account of geographic and other barriers. The use of technology to deliver interventions to veterans with posttraumatic stress disorder (PTSD) has been a particular focus within VHA. Much less attention has been paid to the use of telehealth technologies to diagnose veterans with PTSD for both treatment and/or disability compensation purposes, in spite of the need for such services. The literature evaluating the use of video teleconferencing methods in the assessment of PTSD is limited; to our knowledge, only 1 previous study has been published. The current study evaluated the psychometric characteristics of the Clinician Administered PTSD Scale (CAPS) administered by video teleconferencing with a larger and more diverse sample of veterans. The CAPS raters had high interrater reliability and there were strong correlations between face-to-face CAPS assessments and video teleconferencing CAPS assessments for diagnosis and total severity. The results suggest that the CAPS can and should be used via video teleconferencing with veterans who have barriers to face-to-face evaluations.

Data suggest anxious drivers may engage in problematic behaviors that place themselves and others at increased risk of negative traffic events. Three domains of problematic behavior--exaggerated safety/caution, performance deficits, and hostile/aggressive behaviors--previously were identified during development of the Driving Behavior Survey (DBS), a novel measure of anxiety-related behavior. Extending this research, the current study examined the psychometric properties of DBS scores among individuals with posttraumatic stress disorder (PTSD) subsequent to motor vehicle trauma (N=40). Internal consistencies and 12-week test-retest reliabilities for DBS scales ranged from good to excellent. Comparison of scores to normative student data indicated dose-response relationships for safety/caution and performance deficit subscales, with increased frequency of anxious behavior occurring within the PTSD sample. Associations with standard clinical measures provide additional evidence for anxiety-related driving behavior as a unique marker of functional impairment, distinct from both avoidance and disorder-specific symptoms.

There is a need to identify alternative treatment options for posttraumatic stress disorder (PTSD), especially among veterans where PTSD tends to be more difficult to treat and dropout rates are especially high. One potential alternative is written exposure therapy, a brief intervention shown to treat PTSD among civilians effectively. This study investigated the feasibility and tolerability of written exposure therapy in an uncontrolled trial with a sample of 7 male veterans diagnosed with PTSD. Findings indicated that written exposure therapy was well tolerated and well received. Only 1 of the 7 veterans dropped out of treatment, no adverse events occurred during the course of treatment, and veterans provided high treatment satisfaction ratings. Clinically significant improvements in PTSD symptom severity were observed for 4 veterans at posttreatment and 6 veterans at the 3-month follow up. Moreover, 5 of the 7 veterans no longer met diagnostic criteria for PTSD 3 months following treatment. These findings suggest that written exposure therapy holds promise as a brief, well tolerated treatment for veterans with PTSD. However, additional research using randomized controlled trial methodology is needed to confirm its efficacy.

Psychological distress and coping strategies following intimate partner violence (IPV) victimization may impact survivors' risk for future IPV. The current study prospectively examined the impact of distinct posttraumatic stress disorder (PTSD) symptom clusters (reexperiencing, avoidance, numbing, and hyperarousal), dissociation, and coping strategies (engagement and disengagement coping) on IPV revictimization among recently abused women. Women (N = 69) who were seeking services for IPV and experienced their most recent episode of physical IPV between 2 weeks and 6 months prior to study enrollment completed measures of physical IPV, psychological distress, and coping strategies at baseline and at 6-month follow-up. The women averaged 36 years of age and 67% of the sample was African American. Separate Poisson regression analyses revealed that PTSD hyperarousal symptoms, dissociation, engagement coping, and disengagement coping each significantly predicted physical IPV revictimization at the 6-month follow-up (with effect sizes ranging from a 1.20-1.34 increase in the likelihood of Time 2 physical IPV with a 1 SD increase in the predictor). When these significant predictors were examined together in a single Poisson regression model, only engagement and disengagement coping were found to predict physical IPV revictimization such that disengagement coping was associated with higher revictimization risk (1.29 increase in the likelihood of Time 2 physical IPV with one SD increase in disengagement coping) and engagement coping was associated with lower revictimization risk (1.30 decrease in the likelihood of Time 2 physical IPV with one SD increase in engagement coping). The current findings suggest that coping strategies are important and potentially malleable predictors of physical IPV revictimization.
