RESUMEN
OBJECTIVE: Trauma-informed guilt reduction therapy (TrIGR), a six-session cognitive behavioral therapy targeting trauma-related guilt and distress, reduces guilt and symptoms of posttraumatic stress disorder (PTSD) and depression, yet little is known regarding how and why TrIGR may be effective. METHOD: This study examined treatment-related changes in avoidant coping and trauma-related guilt cognitions as possible mediators of treatment effects on PTSD and depression outcomes at 3- and 6-month follow-up. Data were from a randomized controlled trial for treatment of trauma-related guilt comparing TrIGR and supportive care therapy among 145 post-9/11 US veterans (Mage = 39.2 [8.1], 93.8% male). RESULTS: At pretreatment, most (86%) met PTSD criteria. Intent to treat analyses using parallel mediation models indicated changes in guilt cognitions, but not avoidant coping, mediated the effect of TrIGR on reducing PTSD severity at 3-month (a × b = -0.15, p < 0.01, 95% CI: [-0.24 to -0.06], p = 0.001) and 6-month (a × b = -0.17, 95% CI: [-0.26 to -0.07], p = 0.001) follow-up. Similarly, changes in guilt cognitions, but not avoidant coping, mediated the effect of TrIGR on reducing depression severity at 3-month (a × b = -0.10, 95% CI: [-0.18 to -0.02], p = 0.02) and 6-month (a × b = -0.11, 95% CI: [-0.20 to -0.03], p = 0.01) follow-up. CONCLUSIONS: Compared to guilt cognitions, changes in avoidant coping were less integral to downstream PTSD and depression symptom reduction. Guilt cognition change may be a salient active ingredient of PTSD and depression treatment for those with trauma-related guilt and a key therapy element to which providers should be attuned.

OBJECTIVE: Despite effective treatment options for posttraumatic stress disorder (PTSD), many patients do not complete therapy. This includes U.S. active duty service members, yet factors linked to attendance in this population remain understudied and dropout remains difficult to predict. Additionally, most studies have not examined samples with PTSD and co-occurring major depressive disorder (MDD) despite high rates of comorbidity. METHOD: The current study explored predictors of dropout among service members with comorbid PTSD and MDD (N = 94) randomized to cognitive processing therapy enhanced with behavioral activation (BA + CPT) or CPT as part of a clinical trial. RESULTS: Using the Fournier approach, only two predictors were associated with lower dropout risk among over 20 examined: shorter duration between pretreatment assessment and Session 1 (p = .041) and past 3-month PTSD treatment engagement (p = .036). CONCLUSION: Results suggest the possible utility of early momentum in starting therapy and leveraging recent treatment to improve attendance. However, this study also highlights the possible limitations of commonly assessed pretreatment factors in predicting attendance and current challenges in measuring dropout risk. Strategies to improve prediction, such as shifting focus to assess modifiable factors and processes more proximal to dropout during treatment, may be needed.Trial registration: ClinicalTrials.gov identifier: NCT02874131.
RESUMEN
INTRODUCTION: Trauma-related guilt is common, associated with posttraumatic mental health problems, and can persist after posttraumatic stress disorder (PTSD) treatment. We compared the efficacy of two six-session psychotherapies, Trauma-Informed Guilt Reduction (TrIGR) and Supportive Care Therapy (SCT), for reducing trauma-related guilt. TrIGR helps patients accurately appraise their role in the trauma and re-engage in values. In SCT, patients guide session content. METHODS: A total of 184 veterans seeking VA mental health services were enrolled across two sites; 145 veterans (mean age: 39.2 [8.1]; 92.4% male; 84.8% with PTSD) who endorsed guilt related to a traumatic event that occurred during a post 9/11 Iraq or Afghanistan deployment were randomized and assessed at baseline, posttreatment, 3- and 6-month follow-up. RESULTS: Linear mixed models using intent-to-treat analyses showed guilt decreased in both conditions with a greater decrease for TrIGR (treatment × time, -0.22; F 1, 455.2 = 18.49, p = .001; d = 0.92) than supportive therapy. PTSD and depressive symptoms showed the same pattern. TrIGR had significantly higher likelihood of PTSD treatment response (67% vs. 40%), loss of PTSD diagnosis (50% vs. 14%), and meaningful change in depression (54% vs. 27%) than supportive therapy. Psychological distress and trait shame improved in both conditions. Quality of life did not change. CONCLUSIONS: Targeting guilt appears to be an effective means for reducing posttraumatic symptoms and distress.

OBJECTIVE: Exposure therapies (e.g., prolonged exposure [PE]), are first-line interventions for posttraumatic stress disorder but remain underutilized, partially due to providers' negative beliefs about these interventions. We examined two experimental strategies aimed at enhancing beliefs towards PE and subsequent utilization. METHOD: Clinicians (N = 155) were randomized to one of three conditions presenting a PE rationale: basic, empirically-based, or emotionally-based description. Participants were rerandomized to write or not write arguments for utilizing PE. Before and after PE rationales and 1-month later, participants completed questions about PE beliefs and utilization. RESULTS: Participants reported small yet durable belief change across all rationale conditions, with greatest change following the empirically-based description. Across conditions, belief change was not impacted by writing condition or associated with utilization. CONCLUSION: Addressing negative beliefs with empirical information may be a brief, cost-effective strategy to improve clinicians' beliefs toward PE. Complementary strategies that leverage belief modification to increase utilization are needed.

OBJECTIVE: Even after the most effective posttraumatic stress disorder (PTSD) treatments, symptoms often persist. Understanding residual symptoms is particularly relevant in military populations, who may be less responsive to PTSD interventions. METHOD: The sample consisted of 282 male service members who engaged in a residential PTSD treatment program at a military treatment facility that provided evidence-based PTSD psychotherapies and adjunctive interventions. PTSD and depression symptoms were assessed before and after treatment and weekly during treatment via the PTSD Checklist-Military Version and Patient Health Questionnaire-8. Logistic regression with Hochberg's step-up procedure compared the likelihood of individual residual symptoms between service members who did (n = 92, 32.6%) and did not (n = 190, 67.4%) experience clinically significant PTSD change (≥ 10-point PTSD Checklist-Military Version reduction). RESULTS: Not achieving clinically significant PTSD change was associated with greater odds of nearly all residual symptoms (OR = 2.03-6.18), excluding two Patient Health Questionnaire-8 items (appetite and psychomotor changes). Among service members experiencing clinically significant PTSD change, concentration difficulties (73.3%), physical reactions to reminders (71.1%), and intrusions (70.8%) were PTSD symptoms most likely to persist. Poor sleep (56.2%), low energy (50.0%), and concentration difficulties (48.3%) were the most common for depression. CONCLUSIONS: To our knowledge, this study is the first to examine residual PTSD and depression symptoms following residential PTSD treatment for active duty service members. Given the low rates of clinically significant PTSD change and the high frequency of residual symptoms, strategies may be needed to improve residential PTSD treatment outcomes in the military.

RESUMEN
BACKGROUND: Unsafe storage of firearms is associated with increased risk of suicide.. However, contemporary population-based data on the prevalence and correlates of firearm storage practices among veterans are limited. METHODS: Data were from the 2022 National Health and Resilience in Veterans Study, a nationally representative sample of 2441 veterans. Analyses examined: (1) the prevalence of firearm storage practices; (2) sociodemographic, psychiatric, and clinical characteristics associated with storing firearms loaded and/or in non-secure location; and (3) associations between types of potentially traumatic events and storage practices. RESULTS: More than half of veterans reported owning one or more personal firearms (50.9%). Among firearm owners, 52.9% reported some form of unsafe firearm storage practice (i.e., loaded and/or non-secure location), with 39.9% reporting that they stored one or more firearms loaded. After adjusting for sociodemographic characteristics, major depressive, alcohol and drug use disorders, direct trauma exposures, future suicidal intent, and traumatic brain injury were associated with storing firearms loaded and/or in a non-secure location (ORs = 1.09-7.16). Veterans with a history of specific forms of direct trauma exposure (e.g., physical assault) were more likely to store firearms unsafely. LIMITATIONS: Cross-sectional design precludes causal inference. CONCLUSIONS: Half of U.S. veterans who own firearms store at least one personal firearm loaded and/or in a non-secure location, with approximately four-in-ten keeping a loaded firearm in the home. These high rates underscore the importance of nationwide training initiatives to promote safe firearm storage for all service members and veterans, regardless of risk status, as well as for healthcare professionals working with veterans.

Depression frequently co-occurs with posttraumatic stress disorder (PTSD), including among active duty service members. However, symptom heterogeneity of this comorbidity is complex and its association with treatment outcomes is poorly understood, particularly among active duty service members in residential treatment. This study used latent profile analysis (LPA) to identify symptom-based subgroups of PTSD and depression among 282 male service members in a 10-week, residential PTSD treatment program with evidence-based PTSD psychotherapies and adjunctive interventions. The PTSD Checklist-Military Version and Patient Health Questionnaire-8 were completed by service members at pre- and posttreatment and weekly during treatment. Multilevel models compared subgroups on PTSD and depression symptom change across treatment. LPA indicated four subgroups provided optimal fit: Depressive (high depression severity, low PTSD avoidance; n = 33, 11.7%), Avoidant (high PTSD avoidance, moderate depression severity; n = 89, 31.6%), Moderate (moderate PTSD and depression severity; n = 27, 9.6%), and Distressed (high PTSD and depression severity; n = 133, 47.2%). Treatment response differed across classes for both PTSD and depression outcomes (time × LPA class interaction ps < 0.001). In PTSD models, post-hoc comparisons indicated the Moderate class was associated with less PTSD symptom improvement relative to the other classes (ps < 0.006). In depression models, symptom reduction was greatest for the Distressed and Depressive subgroups relative to the other two classes (ps < 0.009). Study results provide an initial model for two prevalent, impairing disorders among service members and show how these symptom-based subgroups may differentially respond to residential PTSD treatment.

High rates of cannabis use among people with posttraumatic stress disorder (PTSD) have raised questions about the efficacy of evidence-based PTSD treatments for individuals reporting cannabis use, particularly those with co-occurring alcohol or other substance use disorders (SUDs). Using a subset of four randomized clinical trials (RCTs) included in Project Harmony, an individual patient meta-analysis of 36 RCTs (total N = 4046) of treatments for co-occurring PTSD+SUD, we examined differences in trauma-focused (TF) and non-trauma-focused (non-TF) treatment outcomes for individuals who did and did not endorse baseline cannabis use (N = 410; 70% male; 33.2% endorsed cannabis use). Propensity score-weighted mixed effects modeling evaluated main and interactive effects of treatment assignment (TF versus non-TF) and baseline cannabis use (yes/no) on attendance rates and within-treatment changes in PTSD, alcohol, and non-cannabis drug use severity. Results revealed significant improvements across outcomes among participants in all conditions, with larger PTSD symptom reductions but lower attendance among individuals receiving TF versus non-TF treatment in both cannabis groups. Participants achieved similar reductions in alcohol and drug use across all conditions. TF outperformed non-TF treatments regardless of recent cannabis use, underscoring the importance of reducing barriers to accessing TF treatments for individuals reporting cannabis use.

Dropout is a ubiquitous psychotherapy outcome in clinical practice and treatment research alike, yet it remains a poorly understood problem. Contemporary dropout research is dominated by models of prediction that lack a strong theoretical foundation, often drawing on data from clinical trials that report on dropout in an inconsistent and incomplete fashion. In this article, we assert that dropout is a critical treatment outcome that is worthy of investigation as a mechanistic process. After briefly describing the scope of the dropout problem, we discuss the many factors that limit the field's present understanding of dropout. We then articulate and illustrate a transdiagnostic conceptual framework for examining psychotherapy dropout in contemporary research, concluding with recommendations for future research. With a more comprehensive understanding of the factors affecting retention, research efforts can shift toward investigating key processes underlying treatment dropout, thus, boosting prediction and informing strategies to mitigate dropout in clinical practice.

Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) frequently co-occur and can cause significant impairment. Data are lacking as to whether interventions targeting both PTSD and MDD may improve treatment outcomes among individuals with this comorbidity compared with existing evidence-based PTSD treatments alone. This randomized trial compared the effectiveness of cognitive processing therapy (CPT) enhanced with behavioral activation (BA+CPT) versus CPT among 94 service members (52 women and 42 men; age M = 28.5 years) with comorbid PTSD and MDD. The primary outcome was clinician-administered depression symptom severity on the Montgomery-Åsberg Depression Rating Scale (MADRS) from pretreatment through 3-month follow-up. Intent-to-treat analyses using multilevel models showed statistically and clinically significant decreases in MADRS scores for both conditions over time, with no significant differences between BA+CPT and CPT. Secondary depression and PTSD symptom outcomes followed a similar pattern of results. For diagnostic MDD and PTSD outcomes using available data, no statistically significant differences between treatments emerged at posttreatment or 3-month follow-up. Sessions attended, dropout rate, and treatment satisfaction did not significantly differ between treatments. Outcomes were comparable for both treatments, suggesting that BA+CPT and CPT were similarly effective psychotherapy options for comorbid PTSD and MDD.

INTRODUCTION: This study aimed to identify the prevalence and correlates of firearm ownership in a large, contemporary, nationally representative sample of U.S. military veterans. METHODS: Data were analyzed from the 2022 National Health and Resilience in Veterans Study (N=2,326; mean age=60.2 years). Weighted independent-sample t-tests and chi-square analyses were conducted to compare veterans who did with those who did not report firearm ownership on sociodemographic, military, and psychiatric variables. A multivariable logistic regression analysis using backward elimination was conducted to identify the characteristics independently associated with firearm ownership, and a relative importance analysis was conducted to quantify the relative variance in firearm ownership that was explained by each of the statistically significant main effects. RESULTS: Of the total 2,326 veterans, 1,217 (weighted 50.9%, 95% CI=48.0%, 53.9%) reported owning any firearms. Male sex, conservative political ideology, living in rural area, home ownership, cumulative trauma burden, and lifetime history of alcohol use disorder were most strongly associated with firearm ownership. CONCLUSIONS: This study provides an updated characterization of the prevalence and correlates of firearm ownership among the U.S. veterans. Results of this nationally representative study suggest that firearm ownership in this group may be higher than previously reported and underscore the importance of targeted suicide prevention efforts promoting firearm safety among vulnerable segments of this population.

BACKGROUND: Alcohol use disorder (AUD) is a prevalent public health concern in the U.S. that disproportionately affects veterans relative to civilians. Given changes to the demographic composition of the veteran population and AUD diagnostic criteria in the DSM-5, updated knowledge regarding the epidemiology of DSM-5 AUD in a national sample of veterans is critical to informing the population-based burden of this disorder. METHODS: Data were analyzed from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of 4069 U.S. veterans. Lifetime DSM-5 AUD (mild, moderate, severe) and past-year DSM-5 AUD were assessed using validated self-report measures, and sociodemographic, military, and psychiatric characteristics associated with lifetime and past-year AUD were evaluated. RESULTS: Prevalences of lifetime and past-year DSM-5 AUD were 40.8% (95% confidence interval [CI]=39.2-42.3%) and 10.5% (95%CI=9.6-11.5%), respectively. Lifetime prevalences of mild, moderate, and severe AUD were 20.5%, 8.3%, and 12.0%, respectively. Veterans with lifetime AUD had elevated rates of psychiatric disorders and suicidal behavior, which generally increased as a function of AUD severity. Lifetime AUD was also associated with being younger, male, white, unmarried, retired and experiencing more adverse childhood experiences and traumas. For past-year AUD, being younger, male, white, having more adverse childhood experiences, and experiencing lifetime PTSD were significant correlates. CONCLUSIONS: AUD is highly prevalent among U.S. veterans and associated with substantial psychopathology, including elevated odds of suicidal behaviors. Results underscore the importance of comprehensive screening and preventive efforts for AUD, and interventions that concurrently target overlapping alcohol use and psychiatric difficulties.

OBJECTIVE: Psychiatric and substance use disorders are prevalent among U.S. military veterans, yet many veterans do not engage in treatment. The authors examined characteristics associated with use of mental health care in a nationally representative veteran sample. METHODS: Using 2019-2020 data from the National Health and Resilience in Veterans Study (N=4,069), the authors examined predisposing, enabling, and need factors and perceived barriers to care as correlates of mental health care utilization (psychotherapy, counseling, or pharmacotherapy). Hierarchical logistic regression and relative importance analyses were used. RESULTS: Among all veterans, 433 (weighted prevalence, 12%) reported current use of mental health care. Among 924 (26%) veterans with a probable mental or substance use disorder, less than a third (weighted prevalence, 27%) reported care utilization. Mental dysfunction (24%), posttraumatic stress disorder symptom severity (18%), using the U.S. Department of Veterans Affairs as primary health care provider (14%), sleep disorder (12%), and grit (i.e., trait perseverance including decision and commitment to address one's needs on one's own; 7%) explained most of the variance in mental health care utilization in this subsample. Grit moderated the relationship between mental dysfunction and use of care; among veterans with high mental dysfunction, those with high grit (23%) were less likely to use services than were those with low grit (53%). CONCLUSIONS: A minority of U.S. veterans engaged in mental health care. Less stigmatized need factors (e.g., functioning and sleep difficulties) may facilitate engagement. The relationship between protective and need factors may help inform understanding of veterans' decision making regarding treatment seeking and outreach efforts.

BACKGROUND: The reported prevalence of military sexual trauma (MST) has increased over the past decades in the United States, yet scarce population-based studies have examined the prevalence, correlates, and health burden of MST in the general veteran population. METHODS: Data were from the 2019-2020 National Health and Resilience in Veterans Study, a population-based survey of veterans (nâ¯=â¯4069). ANALYSES: (1) estimated the prevalence of MST; (2) identified sex-stratified sociodemographic, military, and trauma characteristics associated with MST; and (3) examined sex-stratified associations between MST and psychiatric comorbidities, functioning, disability, and treatment utilization. RESULTS: Female veterans reported substantially higher rates of MST (44.2%) than male veterans (3.5%). Relative to male veterans without MST histories, male veterans with MST histories had nearly 3-fold increased odds of reporting future suicidal intent, 2-to-3-fold greater odds of screening positive for current posttraumatic stress disorder (PTSD), depression, and generalized anxiety disorder; and nearly 2-fold increased odds of being disabled. Male veterans with MST histories also scored lower on mental, physical, cognitive, and psychosocial functioning (d'sâ¯=â¯0.16-0.29). Relative to female veterans without MST histories, female veterans with MST histories had 5-fold greater odds of current PTSD, 2-fold greater odds of engaging in mental health treatment, and scored lower on psychosocial functioning and higher on somatic symptoms (both d'sâ¯=â¯0.25). LIMITATIONS: Cross-sectional design precludes causal inference. CONCLUSIONS: A substantial proportion of veterans in the U.S. experience sexual trauma during their military service, and these experiences are associated with an elevated health burden.

A substantial body of evidence supports the use of integrated treatments for posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD). Integrated trauma-focused exposure therapies reduce PTSD symptoms more than comparison treatments, including integrated coping skills therapies, but demonstrate lower attendance, raising questions regarding the relationships between attendance, outcomes, and treatment type. We aimed to examine these relationships in a RCT comparing integrated prolonged exposure (Concurrent Treatment for PTSD and Substance Use Disorders Using Prolonged Exposure, COPE; n = 58), to integrated coping skills therapy (Seeking Safety, SS; n = 52) offered in 12 sessions, with an option to extend up to four additional sessions. Participants were categorized based on number of sessions attended (0-4; 5-8; 9-12; 13-16). Multilevel modeling revealed that only when examining therapy attendance segments individually, clinical outcomes were comparable across treatments except in the 9-12 group, with COPE resulting in greater reductions in PTSD symptoms (p < 0.001), but not in alcohol use. Extending past 12 sessions was not associated with additional clinically meaningful symptom improvement for either treatment. These results suggest that attending a complete or near complete course of exposure therapy may enhance PTSD outcomes relative to non-trauma-focused therapies.

Exposure-based therapies for posttraumatic stress disorder (PTSD) and anxiety disorders remain underutilized, despite their effectiveness and widescale dissemination efforts. This study surveyed a broad range of licensed providers (N = 155) to examine rates at which prolonged exposure (PE) and other interventions are used to treat PTSD and to investigate provider characteristics linked to exposure beliefs and utilization. While 92.3% of clinicians reported understanding of or training in exposure, only 55.5% of providers reported use of PE to treat PTSD. Clinicians with current cognitive behavioral therapy (CBT) orientation, CBT training orientation, a doctoral degree, and training in PE endorsed greater likelihood of exposure utilization for PTSD (ps < .001, ds = 0.82-1.98) and less negative beliefs about exposure (ps < .01, ds = 0.55-2.00). Exposure beliefs also differed based on healthcare setting (p < .001). Among providers trained in exposure (n = 106), master's degree and non-CBT current theoretical orientation were associated with high utilization yet also negative beliefs. Results suggest exposure training, accurate beliefs, and utilization still lag among some groups of providers. Additionally, negative beliefs and misunderstanding of the exposure rationale may persist even among providers who are trained and report high utilization.

The co-occurrence of depression with posttraumatic stress disorder (PTSD) is common and associated with greater severity and impairment than PTSD alone, but the effects on PTSD treatment outcomes are unclear. This study investigated the impact of baseline depression on PTSD symptom change and dropout in a meta-analysis of 44 randomized controlled trials (N = 4,866) of trauma-focused psychotherapies for PTSD. Analyses included 107 active (k = 71) and control (k = 36) conditions. Baseline depression was indexed within samples as (a) continuous symptom severity (e.g., Beck Depression Inventory), standardized across depression measures and (b) proportion of patients with comorbid depressive disorder diagnosis. Among active conditions reporting continuous depression scores (k = 62), greater depression severity predicted smaller PTSD treatment effect sizes (ß = -.36, p = .002), but not dropout (ß = .25, p = .18). Categorical depressive diagnosis rates (k = 29)-reported less frequently-were not associated with treatment effects or dropout in active conditions. Greater depression severity may reflect a risk factor for attenuated response in PTSD psychotherapies, potentially demanding complementary strategies within trauma-focused interventions. Variability between trials in baseline depression symptoms may suggest the need to consider this sample characteristic when comparing treatment outcomes across studies.

Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) frequently co-occur. Integrated treatments are effective, but not all patients respond and predicting outcome remains difficult. In this study, latent class analysis (LCA) identified symptom-based subgroups of comorbid PTSD/AUD among 119 veterans with PTSD/AUD from a randomized controlled trial of integrated exposure therapy (I-PE) versus integrated coping skills therapy (I-CS). Multilevel models compared subgroups on PTSD severity and percentage of heavy drinking days at post-treatment and 3- and 6-month follow-up. LCA revealed three subgroups best fit the data: Moderate PTSD/Low AUD Impairment (21%), High PTSD/High AUD Impairment (48%), and Low PTSD/High AUD Impairment (31%). There was a three-way interaction between time, treatment condition, and subgroup in predicting PTSD outcomes (p < .05). For the Moderate PTSD/Low AUD Impairment class, outcomes at post-treatment and 3-months were similar (ds = 0.17, 0.55), however I-PE showed greater reductions at 6-months (d = 1.36). For the High PTSD/High AUD Impairment class, I-PE demonstrated better post-treatment (d = 0.83) but comparable follow-up (ds = -0.18, 0.49) outcomes. For the Low PTSD/High AUD Impairment class, I-PE demonstrated stronger outcomes at every timepoint (ds = 0.82-1.15). Heavy drinking days declined significantly through follow-up, with an effect of subgroup, but not treatment, on timing of response. This was the first study modeling how PTSD and AUD symptoms might cluster together in a treatment sample of veterans with PTSD/AUD. Symptom-based subgroups show promise in helping understand variability in treatment response among patients with PTSD/AUD and deserve further study.

BACKGROUND: Integrated interventions for comorbid posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) are effective, but many patients prematurely drop out from treatment. Little is known about within-treatment risk factors for dropout, limiting the ability during therapy to identify patients at risk for attrition. METHODS: We examined measures assessing PTSD (PTSD Checklist for DSM-5; PCL-5), alcohol use (Substance Use Inventory; SUI), and patient satisfaction (Client Satisfaction Questionnaire; CSQ-8) as potential within-treatment markers of dropout risk, administered to 110 veterans in a randomized clinical trial of integrated exposure therapy versus integrated coping skills therapy for comorbid PTSD + AUD. Hierarchical Cox proportional hazard models with dropout status as the endpoint assessed effects of PCL-5, SUI, and CSQ-8 on dropout risk, and whether effects differed by treatment modality. RESULTS: A significant interaction between treatment and changes in alcohol use was observed (HR = 2.86, p = .007), where between-session alcohol use was positively associated with dropout hazard rate for those receiving integrated exposure therapy (HR = 2.34, p = .004), but not coping skills therapy (HR = 0.73, p = .19). Specifically, an increase of one drink consumed per day in the interval since last assessment (typically 2-3 weeks) was associated with a 5-fold increase in dropout hazard rate. CONCLUSIONS: The findings provide preliminary evidence of detectable within-treatment markers of dropout during integrated treatment for PTSD + AUD. Study of within-treatment indicators proximal to dropout may help identify at-risk patients and inform timely strategies to boost retention.
