Treatment receipt patterns among individuals with co-occurring posttraumatic stress disorder (PTSD) and substance use disorders

Factors Associated With Increased Substance Use Disorder Care in VA PTSD Specialty Outpatient Treatment

Objective: Substance use disorders (SUDs) commonly co-occur with posttraumatic stress disorder (PTSD). Understanding PTSD clinics that serve higher percentages of patients with PTSD/SUD is crucial for improving SUD care in clinics with lower percentages of such patients. This study examined the differences between Veterans Affairs (VA) PTSD treatment sites with higher percentages ("High%") and lower percentages ("Low%") of patients with PTSD/SUD as well as exploring the roles of the PTSD/SUD specialists. Methods: The study collected quantitative and qualitative data from 18 clinic directors and 21 specialists from 33 VA PTSD specialty outpatient clinics from 2014 to 2016. The clinics were chosen from the top and bottom quartiles based on two criteria: (1) the percentage of patients with PTSD/SUD and (2) the percentage of patients with PTSD/SUD who completed at least three SUD visits within the first month of their SUD treatment. The interviews sought to identify distinguishing characteristics between the High% and Low% clinics in terms of treatment access and practices for patients with PTSD/SUD. Results: More of the High% clinics reported providing evidence-based, patient-centered, and integrated/concurrent PTSD/SUD treatment and had staff members with more up-to-date knowledge and skills than the Low% clinics. We also found the roles of the PTSD/SUD specialists were demanding and confusing, leading to high turnover rates. Conclusions: The two groups of PTSD clinics differed in three key factors: Resources, knowledge and skills of staff members, and local policies. Future research should focus on addressing resource limitations, knowledge gaps, and local policy disparities in Low% clinics. By emulating the practices of High% clinics, VA PTSD clinics can improve SUD care for patients with PTSD/SUD.

The role of neurosteroids in posttraumatic stress disorder and alcohol use disorder: A review of 10 years of clinical literature and treatment implications

Rates of alcohol use disorder (AUD) are increasing in men and women and there are high rates of concurrent posttraumatic stress disorder (PTSD) and AUD. AUD and PTSD synergistically increase symptomatology and negatively affect treatment outcomes; however, there are very limited pharmacological treatments for PTSD/AUD. Neurosteroids have been implicated in the underlying neurobiological mechanisms of both PTSD and AUD and may be a target for treatment development. This review details the past ten years of research on pregnenolone, progesterone, allopregnanolone, pregnanolone, estradiol, testosterone and dehydroepiandrosterone/dehydroepiandrosterone-sulfate (DHEA/DHEA-S) in the context of PTSD and AUD, including examination of trauma/alcohol-related variables, such as stress-reactivity. Emerging evidence that exogenous pregnenolone, progesterone, and allopregnanolone may be promising, novel interventions is also discussed. Specific emphasis is placed on examining the application of sex as a biological variable in this body of literature, given that women are more susceptible to both PTSD diagnoses and stress-related alcohol consumption.

Diagnostic Accuracy of the Primary Care PTSD for DSM-5 Screen (PC-PTSD-5) in Demographic and Diagnostic Subgroups of Veterans

BACKGROUND

The Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) is a screening instrument designed to identify patients with probable PTSD and is mandated to be used in VA primary care settings. However, validation of the diagnostic accuracy of the instrument is lacking in various demographic and diagnostic groups.

OBJECTIVE

To evaluate the diagnostic accuracy of the PC-PTSD-5 in demographically and diagnostically stratified groups of VA primary care patients.

DESIGN, SETTING, AND PARTICIPANTS

Based on a sample of 519 VA primary care patients (40.61% response rate), the PC-PTSD-5 was evaluated against a criterion measure, examining its sensitivity, specificity, and other diagnostic properties. Evaluations were conducted in demographically stratified patient groups, including gender, age, race/ethnicity, marital status, and education, as well as diagnostically stratified groups, in patients with and without a depression, alcohol use, and drug use disorder.

MAIN MEASURES

The MINI-International Neuropsychiatric Interview was the criterion measure against which the PC-PTSD-5 was evaluated.

KEY RESULTS

Among the 10 demographically stratified groups of patients, the PC-PTSD-5 demonstrated a sensitivity between 81.25% (95% C.I.: 54.35 - 05.95) and 100% (95% C.I.: 63.06 - 1000) and its specificity ranged from 80.54% (95% C.I.: 74.70 - 85.55) to 88.31% (95% C.I.: 83.45 - 92.15). Among the 6 diagnostically stratified groups of patients (with and without depression, alcohol use, and drug use disorders), the PC-PTSD-5 exhibited a sensitivity between 88.89% (95% C.I.: 65.29 - 98.62) and 95.92% (95% C.I.: 86.02 - 99.50), and its specificity varied from 60.00% (95% C.I.: 40.60 - 77.34) to 88.14% (95% C.I.: 84.50 - 91.19).

CONCLUSIONS

The PC-PTSD-5, suitable for a diverse range of VA primary care patients, shows satisfactory sensitivity and specificity across various demographic and diagnostic groups. Healthcare providers should be cautious of false positives in patients with depression or substance use disorders, given the potential symptom overlap with PTSD.

Anxiety, distress tolerance, and the relationship between complex posttraumatic stress disorder symptoms and alcohol use in veterans

OBJECTIVES

Little is known about whether distress tolerance and anxiety mediate the relationship between comorbid complex posttraumatic stress disorder (CPTSD) and alcohol use among military veterans. Here, we investigated the contribution of distress tolerance and anxiety on the strength of the CPTSD and alcohol use association. We hypothesized that the impact of a two-factor model of CPTSD derived from subscale scores on the International Trauma Questionnaire (ITQ)-namely ITQ PTSD and ITQ Disturbances in Self Organization (DSO; e.g., issues with affective regulation/self-belief and shame)-on alcohol use severity would be mediated by anxiety but not by distress tolerance.

METHODS

Participants included 403 community-dwelling United Kingdom (UK) veterans (91.64% male, Mage  = 51.15 years, SD = 12.48) recruited as part of a larger, online study.

RESULTS

Findings indicated that the influence of CPTSD symptoms on alcohol use severity was mediated by anxiety, not by distress tolerance, with greater relative impact due to ITQ DSO status than ITQ PTSD status.

CONCLUSIONS

We identified the mediational influence of anxiety and distress tolerance on the association between CPTSD subscales and alcohol use in UK veterans. Interventions for anxiety may be adapted for reducing problematic alcohol use and the impact of CPTSD symptoms in veterans with comorbid PTSD and alcohol use disorder.

Addressing experiences of trauma within Indigenous-focused substance use residential treatment: a systematic review and environmental scan

Indigenous individuals in Canada disproportionally experience higher rates of substance use concerns. This study examined clinical practices currently implemented with Indigenous-led residential treatment facilities to simultaneously address substance use and post-traumatic stress. A systematic review of relevant literature retrieved published approaches to address these concurrent disorders with Indigenous individuals. This review retrieved 35 sources related to trauma and substance use treatment among Indigenous individuals or communities. Among these sources, all leveraged cultural approaches as a dual treatment for trauma symptoms and substance use. Inconsistent results were reported among those sources (n = 3) who analyzed comparisons with wait-list controls or used randomized-controlled designs. Using culture-as-treatment was elaborated upon in the second goal of this study: an environmental scan of Indigenous-led treatment programs and qualitative interviews with 10 treatment center staff to understand how programs may address both substance use and traumatic symptoms among Indigenous-led substance use treatment centers across Canada. When we searched the websites of these centers, we found that approximately 38% (16 of 43) of treatment centers discussed implementing some form of treatment that addressed trauma symptoms in conjunction with primary substance use. Among the 10 staff participants, all discussed how trauma can impede client success in treatment, and ACE-specific programming is useful within their respective treatment programs. Results showed that when manualized treatments are used, they must be adapted to meet the specific needs of Indigenous communities, and culture-as-treatment is a popular approach among Indigenous-led treatment centers, particularly for addressing trauma symptoms.

Mental Health Clinician Practices and Perspectives on Treating Adults with Co-Occurring Posttraumatic Stress and Substance Use Disorders

OBJECTIVE

Posttraumatic stress disorder (PTSD) and substance use disorders (SUD) commonly co-occur and represent a complex, challenging clinical comorbidity. Meta-analytic studies and systematic reviews suggest that trauma-focused treatments are more efficacious than non-trauma focused interventions for co-occurring PTSD/SUD. However, relatively little is known about mental health clinicians' practices or preferences for treating co-occurring PTSD/SUD. The present study aimed to describe the current clinical practices of mental health clinicians who treat PTSD and/or SUD-related conditions and to assess interest in novel integrative treatments for PTSD/SUD.

METHODS

Licensed mental health clinicians (N = 76; Mage = 39.59, SD = 8.14) who treat PTSD and/or SUD completed an anonymous online survey from April 2021 to July 2021.

RESULTS

The majority (61.8%) of clinicians reported using integrative treatments for PTSD/SUD. The most commonly used trauma-focused treatments were 1) Cognitive Processing Therapy (CPT: 71.1%) and 2) Prolonged Exposure Therapy (PE: 68.4%) for PTSD. Approximately half (51.3%) of clinicians endorsed using Relapse Prevention (RP) for SUD. The vast majority (97.4%) of clinicians were somewhat or very interested in a new integrative CPT-RP intervention, and 94.7% of clinicians believed patients would be interested in a CPT-RP intervention. In the absence of an available evidence-based integrative treatment using CPT, 84.0% of clinicians reported modifying extant treatment protocols on their own to address PTSD and SUD concurrently.

CONCLUSIONS

The findings demonstrate mental health clinician support of integrative treatments for PTSD/SUD. The most commonly used trauma-focused intervention was CPT and clinicians expressed strong interest in an integrative intervention that combines CPT and RP. Implications for future treatment development are discussed.

Demographic differences in the cascade of care for unhealthy alcohol use: A cross-sectional analysis of data from the 2015-2019 National Survey on Drug Use and Health

BACKGROUND

The screening, brief intervention, and referral to treatment (SBIRT) model is recommended by the U.S. Preventive Services Task Force to improve recognition of and intervention for unhealthy alcohol use. How SBIRT implementation differs by demographic characteristics is poorly understood.

METHODS

We analyzed data from the 2015-2019 National Survey on Drug Use and Health from respondents ≥18 years old who used an outpatient clinic and had at least one alcoholic drink within the past year. Respondents were grouped into one of three mutually exclusive groups: "no binge drinking or alcohol use disorder (AUD)," "binge drinking without AUD," or "AUD." Outcome variables were likelihood of screening, brief intervention (BI), referral to treatment (RT), and AUD treatment. The demographic predictors on which outcomes were regressed included gender, age, race and ethnicity, sexual orientation, insurance status, and history of military involvement. Consistent with SBIRT guidelines, the entire sample was included in the screening model; screened persons with either binge drinking without AUD or with AUD were included in the BI model; screened persons with AUD were included in the RT model, and persons referred to treatment with AUD were included in the AUD treatment model.

RESULTS

Analyses included 120,804 respondents. Women were more likely than men to be screened, but less likely to receive BI or RT. When referred to treatment, women were more likely than men to receive it. Persons aged ≥50 were least likely to be screened about alcohol, but most likely to receive BI, while persons aged 18-25 were least likely to receive BI or AUD treatment. Racial and ethnic minorities were less likely than White persons to be screened; Asians were less likely to receive RT, and Black persons were less likely to receive treatment than White persons. Persons identifying as gay, lesbian, or bisexual were equally as likely or more likely to receive SBIRT or AUD treatment as those identifying as heterosexual. Persons without insurance were less likely to be screened than those with insurance. Persons with a history of military involvement were more likely to be screened and receive BI and RT than persons who had not served in the military.

CONCLUSIONS

Demographic disparities in SBIRT implementation exist. Addressing the sources of these disparities and minimizing attrition from care could improve outcomes for persons with unhealthy alcohol use.

Perspectives Regarding Medications for Opioid Use Disorder Among Individuals with Mental Illness

Most people with co-occurring opioid use disorder (OUD) and mental illness do not receive effective medications for treating OUD. To investigate perspectives of adults in a publicly-funded mental health system regarding medications for OUD (MOUD), we conducted semi-structured telephone interviews with 13 adults with OUD (current or previous diagnosis) receiving mental health treatment. Themes that emerged included: perceiving or using MOUDs as a substitute for opioids or a temporary solution to prevent withdrawal symptoms; negative perceptions about methadone/methadone clinics; and viewing MOUD use as "cheating". Readiness to quit was important for patients to consider MOUDs. All participants were receptive to discussing MOUDs with their mental health providers and welcomed the convenience of receiving care for their mental health and OUD at the same location. In conclusion, clients at publicly-funded mental health clinics support MOUD treatment, signaling a need to expand access and build awareness of MOUDs in these settings.

Seeking care where they can: A systematic review of global trends in online alcohol treatment utilization among non-veteran and veteran women

Background

Findings from a person-level meta-analysis of online alcohol intervention trials suggest that women disproportionately seek out such interventions (Riper et al., 2018). Although women may be a "hidden population" that is particularly drawn to online alcohol interventions, trial design features may explain women's apparent over-representation in these trials.

Methods

This systematic review examined associations between gender-tailored recruitment/inclusion criteria and proportions of women enrolled in online alcohol intervention trials, evaluated whether community samples have greater proportions of women than clinical samples, and compared country-specific average proportions of women in trials to country-specific proportions of women with Alcohol Use Disorder (AUD).

Results

Forty-four trials met inclusion/exclusion criteria, 34 community samples and 10 drawn from clinical settings; 4 studies included U.S. veterans and were examined separately. The average proportion of community-recruited women across the studies was 51.20% and the average proportion of clinically-recruited women was 35.81%, a difference that was statistically significant. Across the countries with relevant trials, the expected proportion of those with AUD who are women is 27.1% (World Population Review, 2022). Only 2 studies used targeted recruitment for women so no between-group tests were conducted. There was not a statistically significant difference in the proportion of women across trials that did and did not use gender-tailored alcohol inclusion criteria.

Conclusions

Results from this systematic review suggest that study design factors do not account for the marked over-representation of women in online alcohol interventions, indicating that women are indeed a "hidden population" whose needs should be understood and accommodated.

Posttraumatic stress and substance use among military veterans: Associations with distress intolerance and anxiety sensitivity

The co-occurrence of posttraumatic stress disorder (PTSD) and substance use disorders (SUD) is highly prevalent among military veterans and represents a difficult-to-treat comorbidity. Distress intolerance (DI; i.e., the perceived inability to tolerate negative emotional states) and anxiety sensitivity (AS, i.e., the fear of anxiety-related sensations) are two promising targetable mechanisms with potential to predict and improve treatment outcomes for veterans with PTSD/SUD. We hypothesized that PTSD symptom severity would be related to (a) alcohol use severity and (b) drug use severity through DI and AS, evaluated concurrently. Participants included 120 military veterans (98.3% male; M_age = 41.41, SD = 10.77) presenting for psychological services at a Veterans Affairs PTSD/SUD clinic. Results indicated that PTSD symptom severity was related to alcohol use severity through AS, but not DI; and PTSD symptom severity was related to drug use severity through DI, but not AS. Clinical and research implications are discussed.

Distress tolerance: prospective associations with cognitive-behavioral therapy outcomes in adults with posttraumatic stress and substance use disorders

74Distress tolerance (DT; perceived or actual ability to tolerate aversive physical or emotional states) is related to both posttraumatic stress disorder (PTSD) symptoms and substance use disorders (SUD). This investigation evaluates self-report and behavioral measures of DT as potential predictors of PTSD and SUD cognitive-behavioral therapy outcomes. Participants included 41 treatment-seeking adults (53.7% women; 73.2% African American; M_age = 44.90, SD = 9.68) who met at least four symptoms of DSM-5 PTSD and DSM-IV substance dependence, assessed via structured interviews. At baseline (pre-treatment), participants completed the Distress Tolerance Scale (DTS), Mirror-Tracing Persistence Task (MTPT), Breath Holding task, and Paced Auditory Serial Addition Task. The Clinician-Administered PTSD Scale for DSM-5 severity scores and percent days of primary substance use, measured via Timeline Follow-back, were used as indicators of PTSD symptoms and substance use, respectively. Covariates included treatment condition, baseline PTSD symptom severity, and baseline substance use. Lower perceived DT at baseline (DTS total score) was associated with higher PTSD symptom severity at end-of-treatment. Lower behavioral DT at baseline (MTPT duration) was associated with higher substance use at the conclusion of treatment (i.e. proportion of number of use days to total number of days between two final treatment sessions).

Efficacy and acceptability of interventions for co-occurring PTSD and SUD: A meta-analysis

Over the past 20 years, numerous treatments addressing comorbid Posttraumatic Stress Disorder (PTSD) and Substance Use Disorder (SUD) have been developed and tested. The current meta-analysis examined the efficacy and acceptability of the two central treatment types- trauma-focused and non-trauma-focused - compared with all comparators and with cognitive-behavioral manualized SUD treatments immediately post-treatment and at longest follow-up. Twenty-eight randomized clinical trials (N = 3247) were included. There were small to large within-group effects for all forms of active treatment (gs = 0.30-1.11). Trauma-focused but not non-trauma-focused treatments outperformed all comparators on PTSD outcomes at post-treatment. Neither trauma-focused nor non-trauma-focused treatment outperformed all comparators on SUD outcomes at post-treatment. Neither trauma- nor non-trauma-focused treatment outperformed manualized SUD treatments on PTSD outcomes at either time point. Manualized SUD treatments outperformed trauma-focused treatments on SUD outcomes at post-treatment and non-trauma-focused treatments on PTSD outcomes at follow-up. Regarding treatment retention, neither trauma-focused nor non-trauma-focused treatments significantly differed from all comparators or from manualized SUD treatments. Between-group results were largely unchanged in trim-and-fill analyses, but were not robust to fail-safe N. Few moderators were detected. Taken together, results suggest that trauma-focused, non-trauma-focused, and manualized SUD interventions are sound options for individuals with comorbid PTSD/SUD.

Rates and predictors of psychotherapy receipt among U.S. veterans with comorbid posttraumatic stress disorder and substance use disorders

Introduction

Veterans with comorbid posttraumatic stress disorder (PTSD) and substance use disorder (SUD) have complex needs and often do not receive adequate mental health treatment. The purpose of this study was to examine rates and predictors of PTSD-only, SUD-only, or PTSD and SUD psychotherapy receipt among newly diagnosed Veterans with PTSD and SUD.

Design and setting

An administrative dataset including Veterans Health Administration (VHA) users.

Participants

The sample comprised 32,779 United States Veterans with a new PTSD and a new SUD diagnosis in fiscal year 2015.

Measurement

Multinomial logistic regression was used to identify predictors of receipt of any and adequate psychotherapy for PTSD, SUD, or PTSD and SUD across settings. Binomial logistic regression was used to identify predictors of PTSD psychotherapy among those who received any psychotherapy.

Findings

A total of 13,824 (42.17%) Veterans in this sample received any PTSD- or SUD-related therapy in the year following diagnosis. Low rates of veterans received an adequate dose of PTSD-related psychotherapy (6.58%), SUD-related psychotherapy (7.72%), or both PTSD and SUD-related psychotherapy (<1%) In adjusted models, older age, service-connected disability, and psychiatric comorbidities were associated with decreased odds of treatment. Specific types of SUDs, including alcohol, cocaine, and opioid use disorders, along with receipt of diagnosis in a PTSD or SUD clinic, were associated with increased odds of treatment.

Conclusions

Low rates of PTSD and SUD related psychotherapy highlight a need to better engage and retain Veterans with these disorders in care. Predictors of decreased treatment utilization, such as older age, service connection, and bipolar and major depressive disorders, may inform efforts by the VHA to further target and engage Veterans with indicated treatments.
