Life satisfaction following treatment-related reductions in alcohol use and PTSD symptoms: Results from VetChange.

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).

Differential alcohol treatment response by gender following use of VetChange.

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.

Public implementation of a web-based program for veterans with risky alcohol use and PTSD: A RE-AIM evaluation of VetChange.

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.

Understanding motives for and against hazardous drinking and change among returning veterans.

The prevalence of hazardous drinking is elevated among returning veterans of Iraq and Afghanistan wars, particularly among returning veterans and those with co-occurring posttraumatic stress disorder (PTSD) symptoms. Understanding the reasons for drinking as well as motivations for change can tremendously improve intervention efforts. Unfortunately, little is currently known regarding the motivations that might facilitate or hinder change among returning veterans. In the current study, we examined returning veterans' reasons to change or not change drinking through analysis of responses to an open-ended decisional balance exercise. We included 366 returning veterans selected from a larger sample of returning veterans enrolled in a web-based randomized-controlled trial of an online intervention for alcohol use and PTSD. We used qualitative content analysis to systematically classify responses into categories through identification of common themes. Top reasons to change/reduce drinking included reducing negative physical effects, improve finances, and expected social/interpersonal benefits of reduction or abstaining. Top reasons to continue drinking/not change included facilitation of social interaction, promote sleep, and reduce tension. The current study adds to our phenomenological understanding of motivations for and against changing drinking among returning veterans. Whereas many motives were consistent with those of nonveteran samples, others appear to distinguish, and are uniquely salient among, returning veterans (e.g., to manage sleep and PTSD symptoms). These results provide insight into key assessment and intervention points regarding hazardous drinking among returning veterans. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Web-based alcohol intervention for veterans: PTSD, combat exposure, and alcohol outcomes.

OBJECTIVE: The purpose of the current study was to evaluate the relationship between baseline levels of posttraumatic stress disorder (PTSD), combat exposure, and alcohol outcomes in a sample of Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans using a web-based self-management intervention (VetChange) for problem drinking. METHOD: The current study focuses on 523 veterans who participated in a larger randomized clinical trial. Analyses in the current study include (a) multivariable linear regression models to assess the relationship between PTSD, combat exposure, and alcohol variables at baseline, and (b) general linear models accounting for correlated data within subjects to analyze change over time for alcohol outcomes as a function of baseline PTSD symptoms, combat exposure, and covariates. RESULTS: There was a positive association between PTSD symptom severity and alcohol use and alcohol problem severity at baseline. However, participants with higher baseline PTSD symptoms demonstrated a significantly greater reduction in alcohol use during the intervention and a greater reduction in alcohol problems from baseline to 3-month follow-up. Combat exposure severity was positively associated with alcohol problems at baseline. However, veterans with higher exposure demonstrated a greater reduction in average weekly drinking between end of intervention and follow-up, and otherwise showed changes similar to participants with lower exposure. CONCLUSIONS: Higher levels of baseline PTSD symptoms and combat exposure severity did not prevent OEF/OIF veterans from achieving positive alcohol outcomes through participation in a self-management web intervention for problem drinking.

Drinking goal choice and outcomes in a Web-based alcohol intervention: results from VetChange.

OBJECTIVES: The objectives of the paper are to describe characteristics of participants who chose moderation and abstinence drinking goals, and to examine post-treatment drinking outcomes based on patterns of goal choice during a Web-based alcohol intervention for returning U.S. Veterans. METHOD: We conducted a descriptive secondary analysis of a subsample of 305 of 600 Veterans who participated in a clinical trial of VetChange, an 8-module, cognitive-behavioural intervention. Participants self-selected abstinence or moderation drinking goals, initially at Module 3, and weekly during subsequent modules. Alcohol use and alcohol-related problems were measured using the Alcohol Use Disorders Identification Test (AUDIT), Quick Drink Screen (QDS), and Short Inventory of Problems (SIP-2R). RESULTS: Initial goal choices were 86.9% moderation and 13.1% abstinence. Approximately 20% of participants from each initial choice changed goals during the intervention; last goal choices were 68.6% moderation and 31.4% abstinence. Participants who initially chose moderation reported higher percent heavy drinking days at baseline; participants who initially chose abstinence were more likely to report recent substance abuse treatment and were older. Post-intervention levels of alcohol use and alcohol-related problems were significantly reduced in all goal-choice patterns (i.e., Moderation Only, Abstinence Only, Moderation to Abstinence, and Abstinence to Moderation; all measures p < 0.05 or less). Baseline drinking severity did not differentially relate to outcomes across goal-choice patterns. CONCLUSIONS: Participants in a Web-based alcohol intervention for returning U.S. Veterans demonstrated improvements in drinking regardless of whether they chose an abstinence or moderation drinking goal, and whether the goal was maintained or changed over the course of the intervention.

Web intervention for OEF/OIF veterans with problem drinking and PTSD symptoms: a randomized clinical trial.

OBJECTIVE: Veterans who served in Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) commonly experience alcohol misuse and symptoms of posttraumatic stress disorder (PTSD) following their return from deployment to a war zone. We conducted a randomized clinical trial to evaluate the efficacy of a newly developed, 8-module, self-management web intervention (VetChange) based on motivational and cognitive-behavioral principles to reduce alcohol consumption, alcohol-related problems, and PTSD symptoms in returning combat veterans. METHOD: Six hundred participants, recruited through targeted Facebook ads, were randomized to either an Initial Intervention Group (IIG; n = 404) or a Delayed Intervention Group (DIG; n = 196) that waited 8 weeks for access to VetChange. Primary outcome measures were Drinks per Drinking Day, Average Weekly Drinks, Percent Heavy Drinking Days, and PTSD symptoms. Intent-to-treat analyses compared changes in outcome measures over time between IIG and DIG as well as within-group changes. RESULTS: IIG participants demonstrated greater reductions in drinking (p < .001 for each measure) and PTSD symptoms (p = .009) between baseline and end-of-intervention than did DIG participants between baseline and the end of the waiting period. DIG participants showed similar improvements to those in IIG following participation in VetChange. Alcohol problems were also reduced within each group between baseline and 3-month follow-up. CONCLUSIONS: Results indicate that VetChange is effective in reducing drinking and PTSD symptoms in OIF/OEF veterans. Further studies of VetChange are needed to assess web-based recruitment and retention methods and to determine VetChange's effectiveness in demographic and clinical sub-populations of returning veterans.

Web-Based Intervention for Returning Veterans with Symptoms of Posttraumatic Stress Disorder and Risky Alcohol Use.

A substantial number of military personnel who have served in Iraq (Operation Iraqi Freedom; OIF) and Afghanistan (Operating Enduring Freedom; OEF) develop symptoms of posttraumatic stress disorder (PTSD) in response to their military experiences and many of these same individuals will drink in a risky or problematic manner following deployment. If left untreated, PTSD symptoms and alcohol problems can become chronic and have a significant, negative impact on the lives of veterans, their families and communities. Further, OIF and OEF service members are often reluctant to seek treatment for mental health symptoms or alcohol problems secondary to stigma. In order to reach this population it is essential that new strategies and venues for delivering evidence-based care are explored. Web-based interventions are uniquely suited to this cohort of veterans in that they have the potential to reach a significant number of veterans who commonly use the Web and who might not otherwise receive care. This article will review the prevalence of PTSD and alcohol problems among OIF and OEF veterans, common barriers they experience with accessing care in traditional mental health settings, and what is known about the effectiveness of Web-based approaches for PTSD and alcohol problems. It also describes the components of a new Web-based intervention, developed by the authors, that uses motivational enhancement and cognitive-behavioral strategies to intervene with returning veterans who report PTSD symptoms and problem drinking. Recommendations for future directions in working with returning veterans with PTSD and alcohol problems will be offered.

The potential for PTSD, substance use, and HIV risk behavior among adolescents exposed to Hurricane Katrina.

Adverse psychosocial outcomes can be anticipated among youth exposed to Hurricane Katrina. Adolescents are particularly vulnerable to the consequences of this natural disaster and may suffer lasting consequences in the form of psychological morbidity and the development of negative health behaviors due to their exposure. We review existing literature on the effects of exposure to natural disasters and similar traumas on youth and, where data on youth are unavailable, on adults. The effect of natural disasters is discussed in terms of risk for three negative health outcomes that are of particular concern due to their potential to cause long-term morbidity: post-traumatic stress disorder, substance use disorder, and HIV-risk behavior. Where available, data from studies of the effects of Hurricane Katrina are included.

Gender and other psychosocial factors as predictors of adherence to highly active antiretroviral therapy (HAART) in adults with comorbid HIV/AIDS, psychiatric and substance-related disorder.

This study assessed adherence to HAART among 67 HIV-infected adults, and the degree to which gender and psychological factors-including depression, drug and alcohol use, quality of life, and medication side effects-influenced adherence. Although overall adherence was greater than rates reported in similar studies, no significant difference in adherence was observed between men and women in the present sample. Medication side effects were a significant predictor of non-adherence in the sample at large and among women in particular, while alcohol dependence was a significant predictor of non-adherence only in women. Possible explanations are explored.
