PTSD / substance use disorder comorbidity: Treatment options and public health needs

Sex, Adverse Childhood Experiences, and Substance Use Disorders in US Military Veterans: Results From the National Health and Resilience in Veterans Study

OBJECTIVES

US veterans report more adverse childhood experiences (ACEs) than nonveterans, and a greater number of ACEs has been linked to substance use disorders (SUDs). To date, however, no study has examined whether specific ACEs may be linked to SUDs in this population in a sex-related fashion.

METHODS

We analyzed data from the National Health and Resilience in Veterans Study, a nationally representative survey of 4069 US veterans. ACEs, current alcohol use disorder (AUD), and current drug use disorder (DUD) were assessed using validated self-report measures.

RESULTS

Being raised in a household with people with SUDs was independently associated with current AUD. Childhood sexual abuse and having an incarcerated family member were independently associated with current DUD. Sex moderated associations with specific ACEs. Specifically, female veterans who had experienced physical neglect in childhood or were raised with a mentally ill family member in the home were more likely to endorse current AUD and DUD, whereas male veterans who experienced sexual abuse in childhood or who were raised in a home with someone who used substances were more likely to endorse current AUD and DUD.

CONCLUSIONS

Results underscore the importance of targeted and sex-sensitive interventions in addressing potentially unresolved childhood traumas as part of treatment efforts for SUDs in veterans.

A Seeking Safety Mobile App for Recovery from PTSD and Substance Use Disorder: Results of a Randomized Controlled Trial

BACKGROUND

Posttraumatic stress disorder (PTSD) and substance use disorder (SUD) co-occur frequently and have deleterious impact. Seeking Safety (SS) - an evidence-based, present-focused, coping skills model - lends itself to mobile app delivery.

OBJECTIVES

A novel SS mobile app is compared to a control app that lacks the interactivity, social engagement, and feature-richness of the SS app. We hypothesized that the SS app would outperform the control on primary outcome variables (substance use, trauma symptoms) and at least two secondary variables.

METHODS

Outpatients with current PTSD and SUD (n = 116) were randomized to the apps; assessed were pre, post (12 weeks), and 3-month follow-up in this online study.

RESULTS

The SS app outperformed the control on the primary outcomes, but not on secondary outcomes. Also both conditions evidenced significant change over time from pre to post, with gains sustained at follow-up. External medication and supports during the trial did not differ by condition.

CONCLUSION

This first RCT on a SS mobile app had positive results for reduction in substance use and trauma symptoms compared to a control app. This is noteworthy as mental health mobile apps, in general, evidence few positive outcomes. Our substance use finding is also notable as psychosocial interventions in PTSD/SUD populations find it harder to achieve reduction in SUD than trauma symptoms. Our control app may have represented too strong a comparison and weakened our ability to find results on secondary outcomes by condition.

Treating posttraumatic stress disorder and alcohol use disorder comorbidity: Current pharmacological therapies and the future of MDMA-integrated psychotherapy

Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) frequently co-occur in patients who have experienced trauma. This comorbidity leads to a vicious cycle where PTSD symptoms beget heavy drinking and vice versa. There are no FDA-approved medications to treat PTSD-AUD; therefore, individuals suffering from this comorbidity are treated with medication approved to treat the disorders separately or with off-label pharmacological interventions. However, these medications are limited in their efficacy for treating PTSD-AUD comorbidity. Emerging research on the nonclassical psychedelic drug 3,4-methylenedioxymethamphetamine (MDMA) suggests that it may be an effective drug used in conjunction with psychotherapy. The following reviews the current research for clinical pharmacotherapies, as well as MDMA-integrative psychotherapy as they pertain to PTSD and AUD in isolation and co-occurrence. Future directions for the role of psychedelic-integrative therapy for the treatment of this comorbidity are discussed.

A Randomized Controlled Trial for Gambling Disorder and PTSD: Seeking Safety and CBT

Studies show a compelling association between gambling disorder and posttraumatic stress disorder. However, there have been no randomized controlled trials for this co-morbidity. The aim of the current study was to compare two evidence-based models, one that addresses both disorders and another that addresses gambling alone. Sixty-five men and women with gambling disorder and posttraumatic stress disorder were randomized to one of two treatment conditions delivered via telehealth, Seeking Safety (integrated treatment for gambling and posttraumatic stress disorder) or Cognitive-Behavioral Therapy for Pathological Gambling (for gambling alone), in a randomized controlled non-inferiority trial. Primary outcomes were net gambling losses and number of sessions gambling. Secondary outcomes were posttraumatic stress disorder symptoms, coping skills, general psychiatric symptoms, global functioning, and gambling cognitions. Assessment occurred at baseline, 6-weeks, 3 months (end of treatment) and 1-year. On most measures, including primary outcomes, participants improved significantly over time with no difference between treatment conditions. Seeking Safety patients had significantly higher session attendance. Effect sizes were large for gambling, posttraumatic stress disorder and coping. All other measures except one showed medium effect sizes. Therapeutic alliance, treatment satisfaction, and the telehealth format were all rated positively. This was the first randomized trial of Seeking Safety in a gambling disorder population. Seeking Safety showed comparable efficacy to an established gambling disorder intervention; and significantly higher Seeking Safety attendance indicates especially strong engagement. Our finding of overall comparable results between the two treatments is consistent with the comorbidity treatment literature.Trial registration: ClinicalTrials.gov NCT02800096; Registration date: June 14, 2016.

Do adverse experiences predict unemployment and need of psychiatric help after treatment for drug use disorders?

Background: This study prospectively examined the association between adverse experiences (physical abuse, sexual abuse and parental substance use problems [SUPs]), not being employed, in education or training (NEET) and being in need of acute psychiatric help among patients receiving treatment for substance use disorders. Methods: A total of 580 adolescents and early adults aged 15-25 years enrolled in treatment for drug use disorders were included in the analyses. Treatment data were linked to participants' register data on employment, education and acute contact to psychiatric services for the following two years. Multivariable logistic regression models were used to examine associations between the three adverse experiences, NEET and need of acute psychiatric help, adjusting for confounders such as age, gender, ethnicity, treatment response and treatment condition. Results: More than half of the participants were NEET two years after treatment enrolment. After controlling for demographics and treatment conditions, NEET was predicted by parental substance use problems (odds ratio [OR] = 1.89, 95% confidence interval [CI] 1.31- 2.70), exposure to physical abuse (OR = 1.48, 95% CI 1.03-2.13) and non-abstinence (abstinence was negatively associated with NEET, OR = 0.53, 95% CI 0.37-0.76). Being exposed to two (OR = 3.17, 95% CI 1.93-5.21) and three types of adverse experiences (OR = 3.14, 95% CI = 1.47-6.70) predicted NEET more strongly than exposure to one type. One out of 10 participants sought acute care from psychiatric services at least once within two years after treatment. Only sex and ethnic minority status were associated with contacting psychiatric services acutely. Conclusion: The present study suggests that adverse experiences, such as being exposed to parental problematic substance use and physical abuse, may be important predictors for NEET after treatment for SUDs.

Project Harmony: A Meta-Analysis With Individual Patient Data on Behavioral and Pharmacologic Trials for Comorbid Posttraumatic Stress and Alcohol or Other Drug Use Disorders

OBJECTIVE

Treatment efficacy for co-occurring posttraumatic stress disorder (PTSD) and substance use disorders is well established, yet direct evidence for comparative effectiveness across treatments is lacking. The present study compared the effectiveness of several behavioral and pharmacological therapies for adults with co-occurring PTSD and alcohol or other drug use disorders.

METHODS

A systematic search of PsycINFO, MEDLINE, and ClinicalTrials.gov was conducted through December 2020 for trials targeting PTSD, alcohol or other drug use disorders, or both disorders (36 studies, N=4,046). Primary outcomes were severity scores for PTSD, alcohol use, and drug use, estimated via moderated nonlinear factor analysis. Propensity score weight-adjusted multilevel models were used. Model-predicted effect sizes were estimated for each treatment, and comparative effect sizes for each active arm against treatment as usual, at end of treatment and at 12-month follow-up.

RESULTS

Compared with treatment as usual, combining trauma-focused therapy and pharmacotherapy for substance use disorders showed the largest comparative effect sizes for PTSD severity (d=-0.92, 95% CI=-1.57, -0.30) and alcohol use severity (d=-1.10, 95% CI=-1.54, -0.68) at end of treatment. Other treatments with large comparative effect sizes included pharmacotherapies for alcohol or other drug use disorders, trauma-focused integrated therapies, and trauma-focused nonintegrated therapies. Reductions in outcomes for PTSD symptoms and alcohol use were observed for nearly all treatments.

CONCLUSIONS

The findings provide support for treating comorbid PTSD and substance use disorders using a variety of approaches, with alcohol-targeted pharmacotherapies and trauma-focused behavioral therapies as a combination of treatments that lead to early and sustained improvements in PTSD and alcohol use severity. Further treatment development is indicated for combining behavioral and pharmacological treatments for synergized impact and understanding the mechanisms of action and conditions under which each treatment type is optimized.

Practical Considerations for Treating Comorbid Posttraumatic Stress Disorder in the Addictions Clinic: Approaches to Clinical Care, Leadership, and Alleviating Shame

A practical, common-sense framework for recognizing and addressing comorbid posttraumatic stress disorder (PTSD) in the substance use disorder (SUD) clinic is outlined. The article focuses on strategies that can help establish trauma-informed care or augment an existing approach. Interventions are organized around the task of ameliorating shame (or shame sensitivity), which represents a transdiagnostic mediator of psychopathology and, potentially, capacity for change. Countershaming strategies can guide a trauma-responsive leadership approach. Considering the striking rate of underdiagnosis of PTSD among patients with SUD, implementing routine systematic PTSD screening likely represents the single most consequential trauma-informed intervention that SUD clinics can adopt.

Illicit Drug Use, Cognitive Distortions, and Suicidal Ideation Among Homeless Youth: Results From a Randomized Controlled Trial

Illicit drug use and cognitive distortions confer significant risks to youth suicidal thoughts and behaviors. However, there has been limited evidence regarding the efficacy of suicide prevention interventions with homeless youth, especially studies testing whether such interventions can reduce the risk for suicidal ideation associated with illicit drug use. Suicidal homeless youth (N = 150) between the ages of 18 to 24 years were recruited from a drop-in center. Youth were randomly assigned to Cognitive Therapy for Suicide Prevention (CTSP) + Treatment as Usual (TAU) or TAU alone. Youth reported their illicit drug use, cognitive distortions, and suicidal ideation 4 times over 9 months. A multiple-group multilevel structural equation model showed that higher illicit drug use at baseline predicted a slower reduction in cognitive distortions and suicidal ideation in the TAU group. These associations were not found in the CTSP + TAU group, suggesting an interruption of such risk from illicit drug use. Findings suggest that CTSP can reduce the risk of illicit drug use as a treatment barrier towards cognitive distortions and suicidal ideation among homeless youth, with implications to improve treatment efforts and to reduce premature mortality in a vulnerable population.

What's in a name? A data-driven method to identify optimal psychotherapy classifications to advance treatment research on co-occurring PTSD and substance use disorders

Background/Objective

The present study leveraged the expertise of an international group of posttraumatic stress and substance use disorder (PTSD+SUD) intervention researchers to identify which methods of categorizing interventions which target SUD, PTSD, or PTSD+SUD for populations with both PTSD+SUD may be optimal for advancing future systematic reviews, meta-analyses, and comparative effectiveness studies which strive to compare effects across a broad variety of psychotherapy types.

Method

A two-step process was used to evaluate the categorization terminology. First, we searched the literature for pre-existing categories of PTSD+SUD interventions from PTSD+SUD clinical trials, systematic and literature reviews. Then, we surveyed international trauma and substance use subject matter experts about their opinions on pre-existing intervention categorization and ideal categorization nomenclature.

Results

Mixed method analyses revealed that a proliferation of PTSD+SUD treatment research over the last twenty years brought with it an abundance of ways to characterize the treatments that have been evaluated. Results from our survey of experts (N = 27) revealed that interventions for PTSD+SUD can be classified in many ways that appear to overlap highly with one another. Many experts (11/27; 41%) selected the categories of 'trauma-focused and non-trauma focused' as an optimal way to distinguish treatment types. Although several experts reinforced this point during the subsequent meeting, it became clear that no method of categorizing treatments is without flaws.

Conclusion

One possible categorization (trauma-focused/non-trauma focused) was identified. Revised language and nomenclature for classification of PTSD+SUD treatments are needed in order to accommodate the needs of this advancing field.

Healing transgender women of color in Los Angeles: A transgender-centric delivery of Seeking Safety

Background: Transgender women of Color experience disproportionate rates of HIV, depression, and anxiety, and high rates of substance use, attempted suicide, and interpersonal verbal, physical, and sexual violence and assault. However, there are few interventions targeting transgender women of Color that address overlapping health and mental health challenges. Aims: There are two aims/research questions: (1) what are the elements of a transgender-centric model for delivering evidence based interventions and practices?, and (2) does Seeking Safety improve substance use and mental health outcomes for transgender women of Color? Methods: We present a case study of the delivery process of Seeking Safety by Special Service for Groups/Asian Pacific AIDS Intervention Team (SSG/APAIT), and analyze baseline and three month post program participant data (n = 81). Results: The transgender-centric model of intervention delivery consisted of multiple steps, also integrating the structural disadvantages experienced by transgender women of Color. Comparing baseline and three months after completion showed significant decrease in reported alcohol use, depression, and severe anxiety. Discussion: Transgender-centric approaches may lead to programs that significantly improve co-occurring substance use and mental health for transgender women of Color. We recommend that organizations aiming to existing programs include feedback from members of the communities that the adapted programs aim to help, and in addition, train community members to deliver the programs. The statistical results indicate that Seeking Safety, a trauma-based program with a short program delivery timeline, may show longer term effects on substance use and mental health. We recommend that programs targeting substance use and mental health for transgender women of Color should be combined with services that address disadvantage (i.e., lack of access to housing, income/employment, health care).
