The role of symptom reduction in improving health-related quality of life through brief cognitive behavioral therapy.

Brief cognitive behavior therapy (bCBT) is effective in reducing symptoms of depression and anxiety disorders and improving health-related quality of life (HRQoL). However, the mechanisms through which cognitive behavior therapy impact HRQoL are not well understood. This study evaluated whether anxiety and depression symptom reduction is a mechanism of treatment for HRQoL outcomes. METHOD: Using secondary data from a multisite, pragmatic, randomized trial, this study evaluated bCBT vs enhanced usual care in 16 VA community-based outpatient clinics. Ordinary least-squares path analysis testing multiple mediators was used to evaluate the role of change in depression and anxiety symptoms in the relationship between treatment condition and HRQoL. RESULTS: Receiving bCBT (vs. enhanced usual care) was significantly negatively associated with change (reduction) in depression and anxiety scores. The indirect effect of treatment on mental HRQoL was significant with change in depression scores as mediator. A similar pattern was observed for physical HRQoL and change in anxiety scores as mediator. CONCLUSION: Findings suggest reduction of depression and anxiety symptoms as a mechanism through which bCBT for depression promoted improvements in HRQoL, with important implications for understanding how CBT impacts functioning, as well as the utility of bCBT in nontraditional mental health settings.

Patterns of Telehealth Use for Mental Health Treatment Among Hispanic Veterans.

Background: Video-to-home telehealth (VTH) is promising for increasing access to mental health (MH) services. VA Video Connect (VVC) facilitates video-based teleconferencing between patients and providers and can reduce barriers while maintaining clinical effectiveness. Little is known about the preferences of Hispanic veterans for VTH. Methods: A retrospective cohort investigation of VTH for MH care utilization among veterans having at least one MH visit from October 2019 to September 2020. The veterans consisted of 155,492 Hispanic/Latino and 1,544,958 non-Hispanic/Latino. VVC involved face-to-face synchronous video-based teleconferencing between patients and providers, enabling care at home or another private location. The main measures included the percentage of MH encounters delivered through VVC. Results: Compared with non-Hispanic veterans, Hispanic veterans had 3.28% greater percentage of VVC MH encounters. Furthermore, there was a 2.65% increase per month in percentage of VVC MH encounters. Conclusions: Contrary to preconceived notions, Hispanic veterans access VTH at higher rates than their non-Hispanic counterparts.

Getting Connected: a Retrospective Cohort Investigation of Video-to-Home Telehealth for Mental Health Care Utilization Among Women Veterans.

BACKGROUND: Increasingly, women are serving in the military and seeking care at the Veterans Health Administration (VHA). Women veterans face unique challenges and barriers in seeking mental health (MH) care within VHA. VA Video Connect (VVC), which facilitates video-based teleconferencing between patients and providers, can reduce barriers while maintaining clinical effectiveness. OBJECTIVE: Primary aims were to examine gender differences in VVC use, describe changes in VVC use over time (including pre-COVID and 6 months following the beginning of COVID), and determine whether changes over time differed by gender. DESIGN: A retrospective cohort investigation of video-to-home telehealth for MH care utilization among veterans having at least 1 MH visit from October 2019 to September 2020. PARTICIPANTS: Veterans (236,268 women; 1,318,024 men). INTERVENTIONS (IF APPLICABLE): VVC involves face-to-face, synchronous, video-based teleconferencing between patients and providers, enabling care at home or another private location. MAIN MEASURES: Percentage of MH encounters delivered via VA Video Connect. KEY RESULTS: Women veterans were more likely than men to have at least 1 VVC encounter and had a greater percentage of MH care delivered via VVC in FY20. There was an increase in the percentage of MH encounters that were VVC over FY20, and this increase was greater for women than men. Women veterans who were younger than 55 (compared to those 55 and older), lived in urban areas (compared to those in rural areas), or were Asian (compared to other races) had a greater percentage of MH encounters that were VVC since the start of the pandemic, controlling for the mean percentage of VVC MH encounters in the 6 months pre-pandemic. CONCLUSIONS: VVC use for MH care is greater in women veterans compared to male veterans and may reduce gender-specific access barriers. Future research and VVC implementation efforts should emphasize maximizing patient choice and satisfaction.

Assessing Change in Participation in Clinical Evaluations of Deployed Veterans with Medically Unexplained Symptoms.

Many deployed veterans experience issues reintegrating into civilian life. Addressing this in a clinical setting can prove challenging; however, assessing participation, defined as involvement in a life situation by the World Health Organization's International Classification of Functioning, Disability and Health, may be helpful. The Community Reintegration of Injured Service Members-Computer Adaptive Test (CRIS-CAT) is a measure of participation developed and validated in veteran populations. The War Related and Illness and Injury Study Center, which provides comprehensive evaluations to veterans with medically unexplained deployment-related concerns, used the CRIS-CAT as part of their social work evaluations during these visits and follow-up telephone calls. This retrospective review of clinical data examines the link between participation as assessed by the CRIS-CAT and factors that are mutable (such as relationships with others) and immutable (personal characteristics) as assessed in the social work evaluation over 12 months. The findings indicate that these veteran patients did not experience change in their participation as measured by the CRIS-CAT. Multivariable regression models demonstrated relationships only between change in CRIS-CAT scales and baseline scores and race. Article concludes by discussing lessons learned from this evaluation of the utility of the CRIS-CAT in clinical care and in longitudinal evaluation.

A pilot open trial of video telehealth-delivered exposure and response prevention for obsessive-compulsive disorder in rural Veterans.

Exposure and response prevention (ERP) is the gold-standard, evidence-based psychotherapy for obsessive-compulsive disorder (OCD), but few receive it. Video telehealth can increase access to ERP for OCD and may enhance the salience of exposures. This study examined the feasibility, acceptability, and preliminary effectiveness of video telehealth-delivered ERP. We conducted a pilot open trial with 11 Veterans, using mixed quantitative and qualitative methods. Treatment completers (n = 9) had significantly reduced OCD and posttraumatic stress disorder symptoms posttreatment. Patients expressed greater comfort in engaging in ERP at home than in clinics. Therapists reported that seeing patients' home environments helped them understand their symptoms and identify relevant OCD exposures. Results suggest that video telehealth-delivered ERP is feasible and acceptable to patients and therapists and promising for reducing OCD symptoms. Future research should compare its effectiveness to usual care and evaluate patients' preferences for treatment delivery.

Perceived injunctive norms and cannabis-related problems: The interactive influence of parental injunctive norms and race.

Cannabis use among college students is associated with negative consequences, including those that can negatively affect academic functioning. Perceived descriptive and injunctive norms are among the strongest predictors of college cannabis use and related problems, and perceived norms differentially relate to cannabis outcomes depending on the reference group (e.g., close friends, family members). However, no known studies have examined the effect of race on these relationships. Yet, given that African American students are more strongly affected by parental influence than Caucasian students and that they endorse more social motives for cannabis use, African American students may be affected by perceived norms regarding parents and friends differentially from Caucasian students. The current study tested the moderational role of race on the relationship between perceived norms and cannabis use and related problems. Cannabis-using undergraduates (N = 103; 78.6% female) completed an online survey. Race moderated the relationship between injunctive norms regarding parents and cannabis-related problem severity such that among African American students (but not Caucasian students), endorsement of more permissive perceived parental injunctive norms was related to greater cannabis-related problem severity (but not cannabis use frequency). Interactions were not significant between race and descriptive norms or between race and peer injunctive norms. African American students who perceive that their parents are more accepting of cannabis use may be especially at risk for cannabis-related problems. Results underscore the importance of considering cultural factors in identification of vulnerability factors related to cannabis problems.

Cannabis-Related Problems and Social Anxiety: The Mediational Role of Post-Event Processing.

BACKGROUND: Cannabis is the most commonly used illicit drug in the US, and is associated with a range of psychological, social, and physical health-related problems. Individuals who endorse elevated levels of social anxiety are especially at risk for experiencing cannabis-related problems, including cannabis use disorder, despite not using cannabis more often than those with more normative social anxiety. Identification of mechanisms that underlie the relationship between social anxiety and cannabis-related problems may inform treatment and prevention efforts. Post-event processing (PEP, i.e., cognitively reviewing past social interactions/performances) is a social anxiety-related phenomenon that may be one such mechanism. OBJECTIVES: The current study sought to test PEP as a mediator of the relationship between social anxiety and cannabis-related problems, adjusting for cannabis use frequency. METHOD: Cannabis-using (past 3-month) undergraduate students recruited in 2015 (N = 244; 76.2% female; 74.2% Non-Hispanic Caucasian) completed an online survey of cannabis use, cannabis-related problems, social anxiety, and PEP. RESULTS: Bootstrap estimate of the indirect effect of social anxiety through PEP was significant, suggesting PEP is a mediator of the social anxiety-cannabis-related problems relationship. Conclusions/Importance: Treatment and prevention efforts may benefit from targeting PEP among individuals with elevated social anxiety and cannabis-related problems.

Anxiety sensitivity and cannabis use-related problems: The impact of race.

BACKGROUND AND OBJECTIVES: Cannabis is the most widely used illicit substance among young adults. Anxiety sensitivity (AS; ie, fear of anxiety-related symptoms) is positively related to coping motives for cannabis use (which are robustly positively linked to cannabis-related problems). However, AS is unrelated to cannabis use-related problems. Yet, extant studies have been conducted on primarily White samples. It may be that among Black students, AS-physical concerns (ie, fear of physical anxiety-related sensations) are related to cannabis problems given that Black individuals are more likely than White individuals to report experiencing greater and more intense somatic symptoms when experiencing anxiety. Black individuals may rely on cannabis to cope with fear of these somatic symptoms, continuing to use despite cannabis-related problems. METHODS: The current study tested whether race moderated the relation between AS-physical concerns and cannabis problems among 102 (85.3% female) current cannabis using undergraduates who were either non-Hispanic Black (n = 51) or non-Hispanic White (n = 51). RESULTS: After controlling for frequency of cannabis use, income, and gender, race significantly moderated the relation between AS-physical concerns and cannabis use-related problems such that AS-physical concerns significantly predicted cannabis-related problems among Black and not White individuals. DISCUSSION AND CONCLUSIONS: Findings highlight the importance of considering race in identifying psychosocial predictors of cannabis-related problems. SCIENTIFIC SIGNIFICANCE: Intervention strategies for Black cannabis users may benefit from examining and targeting AS-physical concerns. (Am J Addict 2017;26:209-214).

Solitary cannabis use frequency mediates the relationship between social anxiety and cannabis use and related problems.

BACKGROUND AND OBJECTIVES: Individuals with elevated social anxiety are seven times more likely to meet criteria for cannabis use disorders, yet social anxiety is unrelated to more frequent cannabis use. The lack of relation to cannabis use frequency may be at least partially due to lack of attention to cannabis use context. It may be that socially anxious persons engage in frequent solitary cannabis use, perhaps using before social situations in the hope that being intoxicated during the social event will help them feel less anxious. In fact, using cannabis alone has been associated with experiencing more cannabis-related problems in prior work. METHODS: The current study sought to identify whether solitary cannabis use frequency mediated the relationship between social anxiety and cannabis-related problems among 276 current cannabis using undergraduates who completed an online survey of putative predictors of substance use. RESULTS: Social anxiety was robustly related to more frequent solitary (but not social) cannabis use and solitary cannabis use frequency uniquely mediated the relation of social anxiety to cannabis use and related problems. DISCUSSION AND CONCLUSIONS: Frequent solitary use appears to play an important role in the experience of cannabis-related problems among socially anxious persons. SCIENTIFIC SIGNIFICANCE: Intervention strategies may benefit from targeting frequent solitary cannabis use, particularly among at-risk users such as those with elevated social anxiety.

Integrated Cognitive Behavioral Therapy for Comorbid Cannabis Use and Anxiety Disorders.

Cannabis use disorders (CUDs) co-occur with anxiety disorders at high rates, presumably because some individuals with anxiety disorders may rely on cannabis to manage anxiety. Motivation enhancement therapy (MET) combined with cognitive-behavioral therapy (CBT) is an efficacious intervention for CUD, yet outcomes are worse for patients with elevated anxiety. The integration of MET-CBT with False Safety Behavior Elimination Treatment (FSET) may be useful with anxious CUD patients, as the use of cannabis to manage anxiety can be targeted as a false safety behavior. Here, we describe the integrated treatment and the successful use of it among two patients-one with CUD and comorbid social anxiety disorder (SAD) and one with CUD and comorbid SAD and generalized anxiety disorder. Data support the feasibility of this integrated treatment as a viable approach to the treatment of CUD and comorbid anxiety disorders. Future controlled trials are now warranted to further evaluate the intervention.

Social anxiety and cannabis cravings: The influences of parent injunctive norms and tension reduction expectancies.

OBJECTIVES: Socially anxious cannabis users are influenced by cannabis expectancies and normative perceptions. The present study examines the influence of psychosocial factors on cannabis use vulnerability factors as the result of interactions between norms perceptions, social anxiety, and expectancies. METHODS: Participants were 149 (36.2% female) current cannabis users aged 18-36 (M=21.01, SD=3.09). Hierarchical multiple regressions were employed to investigate the predictive value of the social anxiety X injunctive norms X expectancies interaction on cannabis cravings. RESULTS: A three-way interaction emerged in the prediction of cannabis cravings. Simple slopes analyses showed that among individuals with perceptions of greater parent approval of cannabis use (higher injunctive norms), social anxiety was associated with greater cannabis craving when expectancies regarding relaxation and tension reduction were greater (t=2.54, p=.01, ß=1.12). CONCLUSIONS: Among cannabis users with perceptions of greater injunctive norms, social anxiety was associated with greater cannabis craving when tension reduction expectancies were greater. However, social anxiety was unrelated to cannabis craving when expectances were low. This suggests that cannabis craving among socially anxious adults was greatest when cannabis use was viewed as acceptable and expected to reduce tension, and highlights the importance of considering norms, expectancies, and social anxiety in understanding cannabis-related behaviors.

The role of depression and anxiety symptom severity in remotely delivered mental health care.

This study examined differences in mental health characteristics of Veterans who received VA Video Connect (VVC) or audio-only care during initial phases of the COVID-19 pandemic. A cohort of Veterans with primary diagnoses of depressive or anxiety disorders (diagnosed between March 2019 and February 2020) was identified, and data were obtained for Veterans who engaged in virtual care from April to December 2020. Two groups were created: Veterans receiving audio-only care (n = 161,071) and Veterans receiving two or more VVC visits (n = 84,505). Multiple logistic regression models examined symptom severity in the year before COVID as a predictor of treatment modality during COVID. Chi-square tests examined associations between modality and the number of assessments. Symptom severity as evaluated by the nine-item Patient Health Questionnaire and Generalized Anxiety Disorder-7 significantly predicted modality of encounters during the pandemic such that those who had moderate or severe symptoms prior to COVID-19 were more likely than those with low or no symptoms to have two or more VVC encounters during the pandemic. Of those who received VVC, 55.62% had no Patient Health Questionnaire-9 assessments compared to 68.96% of those who received audio-only. In the VVC group, 70.36% had no Generalized Anxiety Disorder-7 assessments compared to 81.02% in the audio-only group. Taken together, these findings suggest that VVC, when compared to audio-only, was used during the pandemic to reach Veterans with more severe mental health symptomatology and to engage in administration of measurement-based care.

A protocol for a randomized controlled trial of exposure and response prevention for veterans with obsessive compulsive disorder.

BACKGROUND: Obsessive compulsive disorder (OCD) is effectively treated with exposure and response prevention (ERP), yet very few veterans receive ERP for OCD within the Veterans Health Administration (VHA). Veterans are a clinically complex population, and no prior research has evaluated the effectiveness of ERP in veterans with OCD or comorbid OCD and posttraumatic stress disorder (PTSD). Given the limited accessibility of ERP-trained providers within VHA, assessment of video telehealth (VTH) delivery of ERP is warranted. METHODS: A sample of 160 veterans with OCD (80 diagnosed with comorbid PTSD) will be randomly assigned to receive up to 16 sessions of ERP or a stress management training control delivered via VTH. Assessments will occur at baseline, posttreatment, and 6-month follow-up. The primary outcome will evaluate the impact of ERP on participants' functioning, and secondary outcomes will include quality of life and OCD symptoms. At posttreatment, qualitative interviews with veterans, clinicians, and administrators will explore barriers and facilitators to treatment delivery, and the implementation potential of ERP. CONCLUSIONS: Results will provide direction for the treatment of OCD and comorbid PTSD in veterans, as well as guidance for future implementation efforts for ERP within VHA.

Identifying Barriers and Facilitators to Veterans Affairs Whole Health Integration Using the Updated Consolidated Framework for Implementation Research.

BACKGROUND: Veterans Affairs (VA) implemented the Veteran-centered Whole Health System initiative across VA sites with approaches to implementation varying by site. PURPOSE: Using the Consolidated Framework for Implementation Research (CFIR), we aimed to synthesize systemic barriers and facilitators to Veteran use with the initiative. Relevance to healthcare quality, systematic comparison of implementation procedures across a national healthcare system provides a comprehensive portrait of strengths and opportunities for improvement. METHODS: Advanced fellows from 11 VA Quality Scholars sites performed the initial data collection, and the final report includes CFIR-organized results from six sites. RESULTS: Key innovation findings included cost, complexity, offerings, and accessibility. Inner setting barriers and facilitators included relational connections and communication, compatibility, structure and resources, learning centeredness, and information and knowledge access. Finally, results regarding individuals included innovation deliverers, implementation leaders and team, and individual capability, opportunity, and motivation to implement and deliver whole health care. DISCUSSION AND IMPLICATIONS: Examination of barriers and facilitators suggest that Whole Health coaches are key components of implementation and help to facilitate communication, relationship building, and knowledge access for Veterans and VA employees. Continuous evaluation and improvement of implementation procedures at each site is also recommended.

A biopsychosocial model of social anxiety and substance use.

Emerging prospective work suggests that individuals with social anxiety disorder (SAD) may be at particular risk for developing substance use disorders (SUD). Yet, little is known about why this may be so. Most research has utilized existing theories of substance use (e.g. tension reduction-based theories) to understand SAD-SUD relations. However, these theories do not address why individuals with social anxiety, in particular, experience such high rates of substance-related problems. A possible explanation may lie in the nature of social anxiety itself, which is characterized not only by chronically elevated negative affective states, but by low positive affect, fear of scrutiny, and social avoidance. These aspects of social anxiety may work in concert to place these especially vulnerable individuals at risk for SUD. The current paper presents a biopsychosocial model of SAD-SUD comorbidity that focuses on several specific facets of social anxiety that may be especially related to SUD risk. The utility of this model is evaluated via a review of the literature on the relations between SAD and substance-related behaviors.

Feasibility of Group-Based Implementation Facilitation for Video Telemental Health.

Video telehealth experienced rapid growth throughout the COVID-19 pandemic in many healthcare sectors, including mental health. The Veterans Health Administration's video telehealth platform, VA Video Connect, has been widely used to reach veterans who may have experienced difficulty accessing care, such as those living in rural areas or other barriers (e.g., transportation). Implementing VVC requires a multifaceted approach, including training providers on technical skills, increasing access to equipment for providers and veterans, and integrating VVC within the culture and processes of the clinic unit. Prior successful VVC implementation efforts in rural areas have focused on simultaneous one-on-one provider and leadership engagement using implementation facilitation (IF). However, given the rapid need for VVC expansion in light of limits and dangers associated with in-person care during the pandemic, our team developed group facilitation to increase the reach of VVC implementation through IF. Group facilitation combined training in technical and policy elements of VVC with IF with groups of providers from clinic units. This approach was designed to rapidly disseminate the necessary knowledge to conduct VVC combined with collaborative problem solving as a team to improve the ability of the clinical team to sustain VVC. Attendees were asked for feedback on the session through multiple choice and open-ended questions. Participants (N = 26) reported being highly satisfied with the training and reported a high degree of confidence in their ability to use VVC. Based on evaluation data and interview feedback, providers and clinic leaders were satisfied with group facilitation. Group facilitation may be a helpful tool in rapidly training clinical teams to implement and sustain video telemental health.

Delivery of Exposure and Response Prevention Among Veterans with Obsessive-Compulsive Disorder.

Veterans with obsessive-compulsive disorder (OCD) often face barriers to receiving evidence-based treatments such as exposure and response prevention (ERP). Through retrospective review of electronic medical records, this study examined the rates of ERP delivery in a national sample of 554 veterans newly diagnosed with OCD in the Veterans Health Administration between 2016 and 2017. Results indicated that only 4% of veterans (n = 22) received any ERP treatment; and, of those, 16 veterans received "true ERP." Veterans who received any ERP were younger than those who did not. ERP was primarily delivered by psychologists in urban facilities along the East and West coasts of the USA. The findings from this study emphasize the need to train more providers to effectively deliver ERP in addition to providing telehealth services to increase access to care for veterans in rural areas.

Black veteran use of video telehealth for mental health care.

Black veterans experience disparities in mental health (MH) care access and are disproportionately affected by COVID-19. Video telehealth to home (VTH) may reduce disparities by addressing barriers, particularly with pandemic-related shifts to remotely delivered care. Considering potential needs for tailored implementation across racial/ethnic groups, we examined differences in VTH use by non-Hispanic Black veterans versus all other races/ethnicities and among Black (Hispanic and non-Hispanic) veterans by age, rurality, and gender during the pandemic. We extracted a cohort of Veterans Health Administration-enrolled veterans receiving at least one MH encounter between October 2019 and September 2020 (n = 1,627,791) from electronic health records. Multilevel linear growth curve models examined the percentage of VTH use for non-Hispanic Black versus other races/ethnicities before and after pandemic onset. Black veteran-only subgroup analyses examined differences by ethnicity in percentage of VTH MH encounters since pandemic onset by age, rurality, and gender, using regression and analysis of covariance models. Despite significant increases in VTH during the pandemic, on average, VTH use was consistently lower for non-Hispanic Black veterans across both periods. During the pandemic, differences in VTH use between non-Hispanic Black and non-Black veterans accelerated over time. VTH use was greater during the pandemic for Black veterans who were Hispanic, younger, urban, and female. Adoption of VTH for MH was low for non-Hispanic Black veterans before COVID-19 and during COVID-19 compared to non-Black groups. Future VTH research and implementation efforts should question why adoption remains low, work to meet cultural needs, and promote equitable adoption for Black veterans.

Differential Impact of COVID-19 on the Use of Tele-mental Health Among Veterans Living in Urban or Rural Areas.

OBJECTIVE: The authors examined the use of Veterans Affairs Video Connect (VVC) for mental health care by rural and urban veterans and the impact of the COVID-19 pandemic on patterns of VVC use. METHODS: Data from 557,668 rural and 1,384,093 urban veterans (collected July 2019-October 2020) from the Veterans Health Administration Corporate Data Warehouse were examined with interrupted time-series models to determine rural versus urban VVC use before and during the initial 7 months of the pandemic. RESULTS: Before COVID-19, rates of VVC use as percentages of all mental health care were higher among rural veterans. After implementation of pandemic restrictions, rural veteran VVC use continued to increase, but this increase was surpassed by that of urban veterans. CONCLUSIONS: These findings highlight the need to monitor emerging disparities in telehealth use and to encourage and support use of VVC and access to mental health care for all veterans, particularly those experiencing barriers to care.

Cannabis use disorder and post-traumatic stress disorder: The prevalence of comorbidity in veterans of recent conflicts.

AIMS: Veterans have high rates of cannabis use, and rates of cannabis use disorder (CUD) are rising among this population. These rising rates are particularly true for veterans with post-traumatic stress disorder (PTSD), which is common among veterans of recent conflicts, Operations Enduring Freedom, Iraqi Freedom, and Operation New Dawn (OEF/OIF/OND). Although prior work has documented links between PTSD and cannabis use, a better understanding of the intersection among CUD, PTSD, and other disorders in real-world clinical practice can inform prevention and treatment efforts. This study examined the prevalence and comorbidities of CUD and PTSD in OFE/OIF/OND veterans. METHOD: The study analyzed data from the Veterans Affairs Corporate Data Warehouse (2010-2016) for returning war veterans who were diagnosed with CUD (N = 46,268). The study determined prevalence of PTSD, and examined additional differences in comorbidities. RESULTS: The prevalence of a comorbid PTSD diagnosis among OEF/OIF/OND veterans with a CUD diagnosis was 72.3%. Further analysis revealed additional co-occurring disorders. Veterans with a diagnosis of CUD and PTSD were more likely to have a comorbid diagnosis of depression (odds ratio, 1.69; 95% CI, 1.62-1.71), panic disorder (odds ratio; 1.58; 95% CI, 1.43-1.75), alcohol use disorder (odds ratio; 1.30; 95% CI, 1.24-1.35), opioid use disorder (odds ratio; 1.52; 95% CI, 1.43-1.62), and insomnia (odds ratio; 1.74; 95% CI, 1.65-1.84) than veterans without a PTSD diagnosis. CONCLUSIONS: Findings highlight that the majority of returning war veterans with CUD are highly complex. Our findings substantiate the need for urgent, comprehensive care for veterans with co-occurring CUD and PTSD, including integrated and transdiagnostic treatment approaches.
