Integrated treatment programs for individuals with concurrent substance use disorders and trauma experiences: A systematic review and meta-analysis

A systematic review and meta-analysis of psychosocial interventions for persons with comorbid anxiety and substance use disorders

BACKGROUND & AIMS

Anxiety and substance use disorders are highly comorbid and represent two of the leading causes of disease burden globally. Psychosocial interventions are important treatment options for people with co-occurring anxiety and substance use disorders (A-SUD). To date, few reviews have assessed the efficacy of psychosocial treatments for patients with A-SUD. This systematic review and meta-analysis aims to synthesize this literature and assess the efficacy of psychosocial interventions among patients with A-SUD.

METHODS

We searched all relevant records published until March 2023 in Medline, EMBASE, PsycINFO, CINAHL and Google Scholar. Two authors extracted and reconciled relevant data and assessed risk of bias. Random effects models were used to calculate effect sizes using Hedges' g for post treatment and follow-up time points. Main outcomes of the review were anxiety, alcohol use, and use of other substances. We examined effects on depression as a secondary outcome since it commonly co-occurs with A-SUD.

RESULTS

Psychosocial interventions for co-occurring A-SUD showed moderate effects on anxiety (g = 0.44), alcohol (Hedges' g = 0.29), and other substance use (g = 0.38) at post intervention. Large effects were observed on depression (g = 0.88) at post intervention with high heterogeneity. These effects were maintained at follow-up for anxiety (Hedges' g = 0.38), other substances (g = 0.44), and depression (g = 0.50). Moderation analyses for demographic factors, intervention characteristics, community level factors, anxiety reduction, and alcohol use reduction, were non-significant.

CONCLUSIONS

The current meta-analysis is the first to investigate specifically the effects of psychosocial interventions on patients with anxiety and a co-occurring SUD. The analyses indicated promising moderate-sized effects of treatment on anxiety, alcohol, all other drug use, and depression. The findings point to important avenues for psychosocial treatment emphasis and development while highlighting critical gaps in knowledge to be addressed in future research.

The mental health and substance use treatment experiences of racially and ethnically minoritised women who have experienced sexual violence

The mental health and substance use treatment experiences of racially and ethnically minoritised women who have experienced sexual violence is not well understood. To address this we conducted a systematic review and meta-synthesis of qualitative studies. Our search strategy included electronic searches of 18 databases and grey literature, citation tracking and reference list screening. Studies were eligible if they presented qualitative data from racially and/or ethnically minoritised women or girls, who had experienced sexual violence at any age and described their experiences of receiving treatment from statutory mental health and/or substance use services. Studies were analysed using meta-ethnography. Fourteen papers based on 12 individual studies were included. Analysis developed three main themes: (1) understanding minoritised women holistically, (2) processing the trauma and beginning the healing and (3) the need for social connectedness and empowering relationships. For minoritised women to benefit from treatment, mental health and substance use services need to challenge the dynamics of the multiple traumas minoritised women experience. Knowledge and understanding of the racial trauma minoritised women experience is limited and many are subjected to further harm from racist practices occurring in some treatment services. Offering culturally safe, trauma-informed care which promotes anti-racist practices may help improve mental health and substance use service responses to minoritised women who have experienced sexual violence.

The ASAM/AAAP Clinical Practice Guideline on the Management of Stimulant Use Disorder

The American Society of Addiction Medicine/American Academy of Addiction Psychiatry (ASAM/AAAP) Clinical Practice Guideline on the Management of Stimulant Use Disorder provides guidance on evidence-based strategies for the treatment of stimulant use disorders (StUDs), stimulant intoxication, and stimulant withdrawal, as well as secondary and tertiary prevention of harms associated with stimulant use. The Clinical Guideline Committee (CGC) comprised experts from ASAM and AAAP representing a range of clinical settings and patient populations. The guideline was developed following modified GRADE methodology. The process included a systematic literature review as well as several targeted supplemental searches. The CGC utilized Evidence to Decision tables to review available evidence and rate the strength of each recommendation. The clinical practice guideline was revised based on external stakeholder review. Key takeaways included: Contingency management represents the current standard of care for treatment of StUDs; Pharmacotherapies may be utilized off-label to treat StUDs; Acute stimulant intoxication can result in life-threatening complications that should be addressed in an appropriate level of care; Secondary and tertiary prevention strategies should be used to reduce harms related to risky stimulant use.

The role of co-occurring disorders in criminal recidivism and psychiatric recovery among adults with opioid use disorder and criminal-legal involvement: A statewide retrospective cohort study

INTRODUCTION

Individuals with opioid use disorder (OUD) in the criminal-legal system commonly present co-occurring mental health disorders. However, evidence-based treatment for high-risk populations such as those with co-occurring disorders is often unavailable within jails and prisons. Coordination of timely and affordable access to behavioral health treatment following incarceration is critical to address the multidimensional needs of people with co-occurring needs. However, the role of co-occurring disorders among adults with OUD and criminal-legal involvement who are accessing community-based treatment is understudied.

METHODS

This retrospective cohort study investigated community and recovery outcomes among 2039 adults with OUD and criminal-legal involvement enrolled in a statewide forensic treatment initiative between October 2015 to March 2018. Using court records and clinical data, we assessed the impact of co-occurring OUD and mental health disorders on criminal recidivism and psychiatric recovery and the moderating role of co-occurring disorders on the relationship between community-based treatment and these outcomes.

RESULTS

We found that 47 % of those with OUD also had an underlying mental health disorder. Co-occurring OUD and mental health disorders predicted higher rates of recidivism during the early stages of treatment. Furthermore, group and individual therapy services were associated with lower odds of recidivism. A co-occurring disorder was an important predictor of more severe behavioral health needs when exiting community-based services and did moderate the relationship between service utilization-specifically group therapy and substance use outpatient services-and psychiatric recovery (i.e., behavioral health needs at exit).

CONCLUSIONS

Co-occurring mental health disorders are highly prevalent among adults with OUD who have criminal-legal involvement, but it appears that they can benefit from social support services in the community. Given the multidimensional needs of this high-risk population, criminal-legal stakeholders and community-based clinicians must work in tandem to develop tailored treatment plans that give individuals with co-occurring OUD and mental health disorders the best chance for success post-incarceration rather than a siloed approach to overlapping disorders.

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.

Ancient medicine for a modern disease: traditional Amazonian medicine to treat substance use disorders

Background: There exists an underexploited opportunity to develop innovative therapeutic approaches to SUDs based upon the complementarity between modern and traditional health systems.Objectives: Illustrate the feasibility and potentiality of such an approach through the comprehensive description of Takiwasi Center's treatment model and program, where health concepts and practices from traditional Amazonian medicine work synergistically with modern psychotherapy and medicine in an intercultural dialog to assist in the rehabilitation of people suffering from SUDs.Methods: The description was built from a review of the literature, institutional data, participatory observation and unstructured interviews with staff, researchers and patients during treatment.Results: Since the foundation of the Takiwasi Center in 1992 in the peruvian Amazon, more than a thousand patients with different socio-cultural, ethnic and religious backgrounds have received residential treatment. We present how traditional Amazonian medicine techniques and health concepts cooperate to complement modern psychology in a therapeutic community setting and propose some hypotheses about the neurobiological, psycho-emotional and spiritual healing mechanisms triggered by the program to help people identify and heal the roots of their substance misuse and addictive behavior. We also summarize quantitative outcomes during treatment showing significant improvements in a wide variety of mental health indicators.Conclusion: Takiwasi Center's program is an option for people seeking non-conventional treatment who are sensitive to traditional Amazonian medicine practices and ready to explore the roots of their addiction. From this intercultural approach, some lessons could emerge toward a broader understanding of SUDs that may result in better patient care.

Interventions for prevention and treatment of substance use in youth with traumatic childhood experiences: a systematic review and synthesis of the literature

Most substance use begins in adolescence. Both childhood trauma and associated post-traumatic stress disorder (PTSD) increase risk for early substance use, which is associated with greater eventual severity of substance use disorders (SUDs). When co-occurring, PTSD and SUD can reinforce and exacerbate each other, necessitating integrated treatment approaches. To systematically review existing literature on interventions for prevention or treatment of SUDs among adolescents (aged 10-24) with a history of trauma, with or without PTSD, we searched databases (PubMed, PsycInfo, CINAHL, Cochrane CENTRAL) using search terms related to substance use, trauma, adolescents, and interventions. Searches identified 8134 unique articles, 68 of which prompted full-text screening. Authors extracted data, applied the Effective Public Health Practice Project Quality Assessment Tool to evaluate the evidence, and synthesized findings. Thirty three articles met eligibility criteria, including 13 RCTs. Twenty studies (10 RCTs) evaluated interventions for substance use and co-occurring problems among youth with a history of trauma, predominantly via individual therapy based on cognitive-behavioral principles, although group therapy, case management, and other approaches have also been studied. Interventions with exposure-based components were infrequent but had robust results and minimal adverse outcomes. Thirteen studies examined differential response of youth with a history of trauma to standard SUD treatments, compared to youth without a history of trauma, with mixed findings. Youth with a history of trauma face elevated risk of SUDs and may respond differently to SUD treatments. Several promising interventions have been recently developed.

Mental Health and Recovery Needs Among Women Substance Use Disorder Treatment Clients With Stalking Victimization Experiences

This study examined mental health and recovery needs at substance use disorder (SUD) program entry and at follow-up ( n = 2064) among: (1) women with no stalking victimization; (2) women with lifetime stalking victimization experiences; and (3) women with recent stalking victimization experiences (within 12 months of program entry). Stalking can be defined as a repeated pattern of behavior that creates fear or concern for safety or extreme emotional distress in the target. Women who experienced any stalking victimization, and particularly recent stalking victimization at program entry, had more recovery needs and increased mental health symptoms. At follow-up, women with any stalking victimization experiences continued to have more recovery needs with few differences between the lifetime and recent stalking victimization groups. Stalking victimization experiences were significantly associated with depression and anxiety symptoms in the multivariate analysis. Addressing stalking victimization during SUD treatment may be important to facilitate recovery.

Parenting stress and competence among mothers of young children with substance use disorders: The roles of trauma and reflective functioning

Posttraumatic stress symptoms are prominent in the lives of parents of young children with substance use disorders (SUD). Parenting experiences, particularly stress and competence, impact parenting behaviors and concomitant child growth and development. Factors that promote positive experiences of parenting, such as parental reflective functioning (PRF), and protect the mother and child from negative outcomes are crucial to understand to develop effective therapeutic interventions. The current US study analyzed baseline data from a parenting intervention evaluation to examine how length of substance misuse, PRF, and trauma symptoms were associated with parenting stress and parenting sense of competence among mothers in treatment for SUDs. Measures included the Addiction Severity Index, PTSD Symptom Scale-Self Report, Parental Reflective Functioning Questionnaire, Parenting Stress Index/Short Form, and Parenting Sense of Competence Scale. The sample included 54 predominantly White mothers with SUDs who had young children. Two multivariate regression analyses found that (1) lower parental reflective functioning and higher posttraumatic stress symptoms were associated with higher parenting stress, and (2) only higher posttraumatic stress symptoms were associated with lower levels of parenting sense of competence. Findings underscore the importance of addressing trauma symptoms and PRF when aiming to improve parenting experiences for women with an SUD.

Adolescents with substance use problems in outpatient treatment: a one-year prospective follow-up study focusing on mental health and gender differences

Background

Although several studies have found a high incidence of coexisting mental health problems among adolescents with substance use problems, follow-up studies addressing how these conditions change over time are rare. The study will describe and analyze indications of mental health problems and how various risk factors predict outcomes 1 year after initial treatment contact. In addition, gender-specific risk factors are explored.

Methods

A clinical sample of 455 adolescents (29% girls, median age 17 years) answered a structural interview at baseline and were followed up using official records 1 year after initiated treatment. Bivariate associations and logistic regressions were conducted to analyse the links between risk factors at the individual, social, and structural levels as well as links between various mental illness symptoms at treatment start and indications of mental health problems 1 year later were analysed.

Results

The results show that mental health problems among adolescents largely persisted 1 year after start of outpatient care for substance use problems. Forty-two per cent of the sample displayed indications of mental health problems at follow-up, and registrations for both outpatient treatment and psychiatric medication were more common among the girls. Girls also reported more mental illness symptoms at treatment start than boys did, especially anxiety. Depression and suicidal thoughts had predictive values regarding indications of mental health problems and small cumulative effects were found for 6–10 co-occurring risk factors.

Conclusions

Adolescents with depression and suicidal thoughts at treatment start should yield attention among clinicians as these general risk factors could predict indication of mental health problems at 1 year follow-up effectively. Also, patients with more than six co-occurring risk factors seem more vulnerable for continued mental health problems. Generally, girls displayed a greater mental health and psychosocial burden at treatment initiation and were more likely to show indication of mental health problems at follow-up. These results suggests that girls are more likely to get psychiatric out-treatment parallel to, or after, substance abuse treatment. We recommend further investigation of gender differences and gender-specific needs in substance use treatment.

Overdose Experiences among People Who Inject Drugs in West Virginia: Personal Loss, Psychological Distress, Naloxone, and Fentanyl

Background: As overdose remains a major public health concern in the United States, it is important to understand the experiences people who inject drugs (PWID) have with overdose. Past experiences during such emergencies are an important determinant of future behavior, including help seeking, which can be lifesaving. Methods: We explored experiences with overdose, using data from 21 in-depth interviews collected from PWID in a rural county in West Virginia (Cabell County). We used an iterative, modified constant comparison approach to synthesize resulting interview data. Results: Participants reported pervasive experiences with overdose, including through their own personal overdose experiences, witnessing others overdose, and losing loved ones to overdose fatalities. Experiencing emotional distress when witnessing an overdose was common among our participants. Many participants reported regularly carrying naloxone and using it to reverse overdoses. Multiple participants described believing the myth that people grow immune to naloxone over time. Concerns about the presence of fentanyl in drugs were also common, with many participants attributing their own and others' overdoses to fentanyl. Conclusions: Our findings have important implications for naloxone access and education, as well as policies and practices to encourage help seeking during overdose events among rural PWID. Participant concerns about fentanyl in the drug supply highlight the need for access to drug checking technologies.

Temporal dynamics of symptom change among veterans receiving an integrated treatment for posttraumatic stress disorder and substance use disorders

The present study examined temporal patterns of symptom change during treatment for comorbid posttraumatic stress disorders (PTSD) and substance use disorders (SUDs). We hypothesized that PTSD symptom severity would predict subsequent-session substance use and that this association would be particularly strong among patients who received an integrated treatment versus SUD-only treatment. Participants were 81 United States military veterans with current PTSD and an SUD who were enrolled in a 12-week, randomized controlled trial examining the efficacy of an integrated treatment called Concurrent Treatment of PTSD and Substance Use Disorders Using Prolonged Exposure (COPE) compared with cognitive behavioral relapse prevention therapy (RP). Lagged multilevel models indicated that PTSD symptom improvement did not significantly predict the likelihood of next-session substance use (likelihood of use: B = 0.03, SE = 0.02, p = .141; percentage of days using B = -0.02, SE = 0.01, p = .172. Neither substance use, B = 1.53, SE = 1.79, p = .391, nor frequency of use, B = 0.26, SE = 0.50, p = .612, predicted next-session PTSD symptom severity in either treatment condition. Stronger associations between PTSD symptoms and next-session substance use were expected given the self-medication hypothesis. Additional research is needed to better understand the temporal dynamics of symptom change as well as the specific mediators and mechanisms underlying symptom change.

Treatment of post-traumatic stress disorder and substance use disorder in adults with a history of adverse childhood experiences: A systematic review of psychological interventions

Background

Adverse childhood experiences (ACEs) have long-term effects on adult health, including unresolved trauma and substance use disorder (SUD). There are hypotheses of a mediating role of emotion regulation. This systematic literature review and narrative synthesis assessed the effectiveness of psychological interventions on emotion regulation, PTSD and SUD symptoms.

Methods

Searches were conducted using the Cochrane Handbook for Systematic Reviews methodology. Eligible studies were randomised controlled trials (RCTs) and quasi-experimental psychological interventions published between 2009 and 2019. Study characteristics, results and methodological quality were systematically analysed.

Results

Thirteen studies, including nine RCTs, were selected. Integrated SUD and PTSD treatments consisted of Seeking Safety, exposure-based treatment, Trauma Recovery and Empowerment Model, and integrated cognitive behavioural therapy. Two studies reported emotion regulation. Five studies found a small to medium positive effect size of psychological interventions on PTSD outcomes. Two studies had a small positive effect size on SUD outcomes and two a small negative effect size. Attrition was high across most studies. Characteristics likely to affect the applicability of the review were described.

Conclusion

The review found some evidence of a small inconsistent positive effect of psychological interventions on PTSD outcomes, and no evidence of effect on SUD outcomes. The range of theoretical models was narrow. Overall quality was low with high clinical heterogeneity and missing key information, particularly on emotion regulation, an important transdiagnostic feature. Further research is required to establish interventions that can treat these multiple conditions with a focus on effectiveness, acceptability, and implementation in real life clinical practice.

A systematic review and meta-analysis of psychological interventions for comorbid post-traumatic stress disorder and substance use disorder

BACKGROUND

The psychological treatment of comorbid post-traumatic stress disorder (PTSD) and substance use disorder (SUD) is clinically challenging, and outcomes are often poor.

OBJECTIVE

This paper describes a systematic review and meta-analysis which sought to establish the current efficacy for a number of established psychological approaches for adults and adolescents, in comparison to interventions for SUD alone, or other active approaches, following a pre-registered protocol.

METHOD

This review followed PRISMA and Cochrane Collaboration guidelines. Data extraction and risk of bias judgements using Cochrane criteria were undertaken by all authors. Primary outcomes were PTSD severity and substance use post-treatment. The quality of findings was assessed using GRADE. Following a comprehensive search, conducted to 13 September 2021, 27 studies were included.

RESULTS

We found a relatively high level of dropout across studies. In our main comparisons, we found no benefits for present-focused treatment approaches aimed at improving coping skills beyond those for SUD-only interventions. We found modest benefits for trauma-focused intervention plus SUD intervention post-treatment for PTSD (standardized mean difference (SMD) = -0.36, 95% confidence interval (CI) -0.64, -0.08), and at 6-13 months for PTSD (SMD = -0.48, 95% CI -0.81, -0.15) and alcohol use (SMD = -0.23, 95% CI -0.44, -0.02). There were no benefits for cognitive restructuring interventions as a group, but we found a modest effect for integrated cognitive behavioural therapy (ICBT) for PTSD post-treatment (SMD = -0.33, 95% CI -0.62, -0.04). There was evidence of some benefit for trauma-focused intervention over present-focused intervention for PTSD from a single study and for reduction in dropout for incentivized attendance for trauma-focused intervention from another single study. Most findings were of very low quality.

CONCLUSION

There is evidence that trauma-focused therapy and ICBT can improve PTSD for some individuals, but many patients do not fully engage with treatment and average treatment effects are modest.

HIGHLIGHTS

For PTSD, evidence was strongest for trauma-focused CBT-based approaches, but effects were modest.There was little evidence of any added benefit on substance use, beyond that of standard addiction treatments, for any included intervention.Dropout from treatment was high.

Long-Term Outcomes for Young People With Substance Use Problems in Outpatient Treatment: Gender-Specific Patterns

This study presents the results of a longitudinal research project focusing on long-term outcomes among young people after initiation of outpatient treatment for substance use problems (SUP) in Sweden. Young people are defined with the age group 13-25 years. A clinical sample of 451 young people (29% girls, median age 17 years) completed a structured interview at baseline and was followed using official records one, two, and 3 years after initiation of treatment. Gender-specific patterns at intake were described and bivariate associations and logistic regressions were calculated to analyse the links between risk factors at treatment start and indications of substance use problems 3 years later. Significantly more boys than girls displayed indications of continued SUP at 3-year follow-up. More specifically, 49% of the boys vs. 35% of the girls were identified through records as still having problems with substance use. Predictive risk factors also displayed gender-specific patterns. Primary drug use frequency and age at intake predicted indications of SUP among boys but not among girls. Placement in foster care/residential homes, depression, and early drug debut had significant predictive value regarding indications of SUP among females but not among males. Girls also displayed a greater psychosocial burden at treatment start, but a more favorable treatment outcome at follow-up. Youths with a heavy risk load at treatment start (i.e., over six risk factors) did not display a greater risk of SUP at 3-year follow-up, although our results suggest that this subgroup has indications of continued problems with mental health. Consequently, future studies should further explore gender-specific treatment pathways for young people with substance use problems. Since women and girls seem to have different risk factors, co-occurring psychiatric problems and more experiences of trauma compared to men, they might need multidimensional and more comprehensive treatment interventions that run over a longer period of time.

Gaming to cope: Applying network analysis to understand the relationship between posttraumatic stress symptoms and internet gaming disorder symptoms among disaster-exposed Chinese young adults

Research has demonstrated that posttraumatic stress disorder (PTSD) is associated with internet-related problematic behaviors. However, studies have not explored the linkage between PTSD symptoms and internet gaming disorder (IGD) symptoms. The current study aimed to investigate the relationship between posttraumatic stress symptoms (PTSS) and IGD symptoms via network analysis. We conducted a cross-sectional study with 341 Chinese young adults directly exposed to a typhoon and examined the network structure of PTSS and IGD symptoms, along with bridge symptoms, to elucidate how they co-occur. Results indicated that 'avoiding external reminders' and 'anhedonia' were identified as the most central symptoms in the PTSD network, whereas 'preoccupation,' 'gaming despite harms', and 'loss of control' ranked highest on centrality in the IGD network. Two bridge symptoms emerged within the combined PTSD and IGD network model: 'concentration difficulties' and 'conflict due to gaming' from among the PTSS and IGD symptoms, respectively. These findings reveal novel associations between PTSS and IGD symptoms and provide an empirically-based hypothesis for how these two disorders may co-occur among individuals exposed to natural disasters.

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.

Interventions for addressing trauma among people with HIV: a narrative review

Traumatic experiences are disproportionately prevalent among people with HIV and adversely affect HIV-related health outcomes. As part of a national cooperative agreement funded by the Health Resources and Services Administration's HIV/AIDS Bureau, we searched the literature for interventions designed to address trauma among people with HIV in the U.S. Our search yielded 22 articles on 14 studies that fell into five intervention categories: expressive writing, prolonged exposure therapy, coping skills, cognitive-behavioral approaches integrated with other methods, and trauma-informed care. Thematic elements among the interventions included adaptating existing interventions for subpopulations with a high burden of trauma and HIV, such as transgender women and racial/ethnic minorities; addressing comorbid substance use disorders; and implementing organization-wide trauma-informed care approaches. Few studies measured the effect of the interventions on HIV-related health outcomes. To address the intersecting epidemics of HIV and trauma, it is critical to continue developing, piloting, and evaluating trauma interventions for people with HIV, with the goal of wide-scale replication of effective interventions in HIV settings.

Cognitive-Behavioral Interventions Targeting Alcohol or Other Drug Use and Co-Occurring Mental Health Disorders: A Meta-Analysis

AIMS

This meta-analysis reviewed 15 clinical trials (18 study sites/arms), examining the efficacy of an integrated cognitive-behavioral intervention (CBI) delivered to individuals with an alcohol or other drug use disorder and a co-occurring mental health disorder (AOD/MHD). Outcomes were alcohol or other drug use and mental health symptoms at post-treatment through follow-up.

METHODS

The inverse-variance weighted effect size was calculated for each study and pooled under random effects assumptions.

RESULTS

Integrated CBI showed a small effect size for AOD (g = 0.188, P = 0.061; I2 = 86%, τ2 = 0.126, k = 18) and MHD (g = 0.169, P = 0.024; I2 = 58%, τ2 = 0.052, k = 18) outcomes, although only MHD outcomes were statistically significant. Analysis by subgroup suggested that effect magnitude varied by type of contrast condition (integrated CBI + usual care vs. usual care only; integrated CBI vs. a single-disorder intervention), follow-up time point (post-treatment vs. 3-6 months) and primary AOD/MHD diagnosis, although these sub-groups often contained significant residual heterogeneity. In a series of mixed effects, meta-regression models, demographic factors were non-significant predictors of between-study heterogeneity. For AOD outcomes, greater effects were observed in higher quality studies, but study quality was not related to effect size variability for MHD outcomes.

CONCLUSIONS

The current meta-analysis shows a small and variable effect for integrated CBI with the most promising effect sizes observed for integrated CBI compared with a single disorder intervention (typically an AOD-only intervention) for follow-up outcomes, and for interventions targeting alcohol use and/or post-traumatic stress disorder. Given the clinical and methodological variability within the sample, results should be considered a preliminary, but important step forward in our understanding of treatment for co-occurring AOD/MHD.

Naturalistic Evaluation of an Adjunctive Yoga Program for Women with Substance Use Disorders in Inpatient Treatment: Within-Treatment Effects on Cravings, Self-efficacy, Psychiatric Symptoms, Impulsivity, and Mindfulness

Addiction continues to be a major public health concern, and rates of relapse following currently-available treatments remain high. There is increasing interest in the adjunctive use of mindfulness-based interventions, such as yoga, to improve treatment outcomes. The current study was a preliminary naturalistic investigation of a novel trauma-informed yoga intervention in an inpatient treatment program for women with substance use disorder (SUD). Changes and differences in somatic symptoms, psychiatric symptoms, and psychological mechanisms were evaluated in women receiving treatment-as-usual (n = 36) and treatment-as-usual plus the yoga intervention (n = 42). For both groups, statistically significant within-subjects changes were present for somatic and psychiatric symptoms, cravings, self-efficacy, and multiple facets of impulsivity and mindfulness. Compared to standard treatment alone, participants in the treatment plus yoga condition significantly improved in range of motion and the Lack of Premeditation facet of impulsivity. Although most domains were not selectively affected, these initial within-treatment findings in this naturalistic evaluation suggest some promise for adjunctive yoga and a need for further evaluation, especially using larger samples and longer term follow-up.

A Comparison of Cognitive Processing Therapy and Seeking Safety for the Treatment of Posttraumatic Stress Disorder in Veterans

To compare the outcomes of Seeking Safety (SS) and cognitive processing therapy (CPT) in veterans with PTSD in a specialty clinic of an urban VA medical center. Retrospective chart review of electronic medical records was conducted for 420 veterans with PTSD who received treatment with either CPT (n = 227) or SS (n = 193) in group setting. 1) treatment completion rate, 2) self-reported PTSD symptom severity measured by PTSD checklist (PCL), and 3) additional mental health services received within 12 months after treatment. Data were analyzed for the 160 who had both a pre and post PCL documented in their charts. The final analysis sample included n = 94 for CPT and n = 66 for SS veterans with a mean age of 49.71[SD = 14] years, 24 women [15%]; mean baseline PCL score was 68.41 [9]. Significantly more veterans completed SS treatment (SS, 59 [89%] than CPT, 47 [50%] (p = <.001). However, PCL score decreases were significantly greater for patients who completed CPT treatment than those in SS (treatment x time interaction, 9.60 vs.4.98, respectively; difference, 4.62; t₈₄ = 2.16; p = .02). The patients who received SS used significantly more mental health services of the PTSD clinical team than patients who completed CPT treatment (p = .01). The results of this study demonstrate the need for alternative approaches where dually diagnosed patients would not be delayed in their receipt of trauma-focused care - i.e., where treatment is initiated concurrently rather than sequentially to substance abuse treatment.

The impact of poly-traumatization on treatment outcomes in young people with substance use disorders

BACKGROUND

It is believed that clients with psychological trauma experiences have a poor prognosis with regard to treatment participation and outcomes for substance use disorders. However, knowledge on the effect of the number of trauma experiences is scarce.

METHODS

Using data from drug use disorder (DUD) treatment in Denmark, we assessed the impact of having experienced multiple potentially traumatic experiences on DUD treatment efficacy. Baseline and follow-up data from 775 young participants (mean age = 20.2 years, standard deviation = 2.6) recruited at nine treatment centers were included in analyses.

RESULTS

Analyses showed that participants who were exposed multiple trauma experiences also reported a significantly higher intake of cannabis at treatment entry, and a lower well-being score than participants who reported less types or no types of victimization experiences. During treatment, patients with multiple types of trauma experiences showed a slower rate of reduction of cannabis than patients with few or no trauma experiences. The number of trauma types was not associated with number of sessions attended or the development of well-being in treatment.

CONCLUSION

Overall, the results show that although traumatized youth in DUD treatment show up for treatment, helping them to reduce substance use during treatment is uniquely challenging.

Association of symptom severity, pain and other behavioral and medical comorbidities with diverse measures of functioning among adults with post-traumatic stress disorder

Post-traumatic stress disorder (PTSD) is an often disabling mental disorder whose management typically focuses on reducing PTSD symptoms. Chronic pain and other comorbidities that commonly accompany PTSD symptoms may also be independently associated with disability. Using data from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions, we examined the independent association of PTSD symptom severity, pain interference, non-PTSD psychiatric and substance use disorders (SUD), and medical illnesses with each of four domains of function: mental health-related quality of life and physical functioning assessed with the Mental Health Composite Score (MCS) and Physical Function Score (PFS) of the Short Form-12; perceived social support from the Interpersonal Support and Evaluation List-12 (ISEL-12); and self-reported past year employment. Among 1779 individuals representing 11 million U.S. adults who met the Diagnostic and Statistical Manual-5 (DSM-5) criteria for Past Year PTSD, the MCS (41.2; SD 12.5), PFS (44.8; SD 13.2) and ISEL-12 (33.6; SD 7.2) indicated substantial disability when compared to population norms, and only 63.6% were employed. Multiple regression showed the MCS had a modest negative association with PTSD symptoms, pain interference, psychiatric multimorbidity and medical comorbidity although not with SUD. PFS and employment had significant negative associations with pain interference and medical comorbidity. ISEL-12 had a weak negative association with PTSD symptoms and non-PTSD psychiatric comorbidity. Common comorbidities thus significantly influence disability associated with PTSD, often more strongly than PTSD symptoms. PTSD treatment may require integrative multimorbidity management beyond a focus on PTSD symptoms.

Psychiatric comorbidity of developmental trauma disorder and posttraumatic Stress disorder: findings from the DTD field trial replication (DTDFT-R)

Background: Developmental Trauma Disorder (DTD) has extensive comorbidity with internalizing and externalizing disorders distinct from posttraumatic stress disorder (PTSD). Objective: To replicate findings of DTD comorbidity and to determine whether this comorbidity is distinct from, and extends beyond, comorbidities of PTSD. Method: DTD was assessed by structured interview, and probable DSM-IV psychiatric disorders were identified with KSADS-PL screening modules, in a multi-site sample of 271 children (ages 8-18 years old; 47% female) in outpatient or residential mental health treatment for multiple (M = 3.5 [SD = 2.4]) psychiatric diagnoses other than PTSD or DTD. Results: DTD (N = 74, 27%) and PTSD (N = 107, 39%) were highly comorbid and shared several DSM-IV internalizing and externalizing disorder comorbidities. Children with DTD with or without PTSD had more comorbid diagnoses (M = 5.7 and 5.2 [SD = 2.4 and 1.7], respectively) than children with PTSD but not DTD (M = 3.8[SD = 2.1]) or neither PTSD nor DTD (M = 2.1[SD = 1.9]), F[3,267] = 55.49, p < .001. Further, on a multivariate basis controlling for demographics and including all potential comorbid disorders, DTD was associated with separation anxiety disorder, depression, and oppositional defiant disorder after controlling for PTSD, while PTSD was associated only with separation anxiety disorder after controlling for DTD. Both DTD and PTSD were associated with suicidality. Conclusions: DTD is associated with psychiatric comorbidity beyond that of PTSD, and DTD warrants assessment for treatment planning with children in intensive psychiatric services.

Prevalence and Correlates of Sex Selling and Sex Purchasing among Adults Seeking Treatment for Cocaine Use Disorder

Exchange sex places individuals with cocaine use disorder (CUD) at particularly high risk for deleterious safety and health outcomes. A substance use treatment provider who is aware of a patient's exchange sex behavior is better able to provide appropriate screening, care, and/or referral to risk reduction services. However, little is known about exchange sex, especially purchasing, among treatment-seeking adults with CUD. The current study examined the prevalence and correlates of sex selling and sex purchasing among treatment-seeking men and women with CUD (n = 109; ClinicalTrials.gov #NCT02896712). Separate binary logistic regressions via backward elimination were used to identify best fitting models for sex selling and sex purchasing. Over 41% of participants endorsed exchange sex within the last 30 days; 20.2% reported selling sex and 30.3% reported purchasing sex. Sex selling and sex purchasing rates differed by gender and race. Number of sexual partners (OR = 5.83, 95% CI = 2.07-16.43), concern about contracting HIV/AIDS (OR = 2.01, 95% CI = 1.31-3.44), cumulative interpersonal trauma exposure (OR = 1.82, 95% CI = 1.20-2.77), years using cocaine (OR = 1.11, 95% CI = 1.03-1.20), drug-related problem days (OR = 1.07, 95% CI = 1.00-1.14), and sexual preference (OR = 9.50, 95% CI = .69-130.35) were retained in the final model estimating sex selling (Nagelkerke R² = .56). In the final sex purchasing model (Nagelkerke R² = .46), gender (OR = 36.17, 95% CI = 2.96-441.75), number of sexual partners (OR = 6.28, 95% CI = 2.69-14.66), number of convictions (OR = 1.13, 95% CI = 1.02-1.25), and drug-related problem days (OR = 0.96, 95% CI = .92-1.01) were retained. Predictive models in this study identified distinct sets of variables related to sex selling and purchasing. Findings may be used to improve identification of exchange sex in the substance use treatment setting and referral to targeted interventions to reduce associated risk.

Posttraumatic Stress Disorder, Antidepressant Use, and Hemorrhagic Stroke in Young Men and Women: A 13-Year Cohort Study

BACKGROUND AND PURPOSE

Antidepressants are commonly prescribed for posttraumatic stress disorder (PTSD) and may increase the risk of bleeding, including hemorrhagic stroke.

METHODS

We prospectively examined independent effects of PTSD, selective serotonin and norepinephrine reuptake inhibitors (SSRI and SNRI) on the risk of incident hemorrhagic stroke in a nationwide sample of 1.1 million young and middle-aged veterans. Time-varying multivariate Cox models were used to examine hemorrhagic stroke risk by PTSD status and use of SSRI or SNRI while adjusting for demographics, lifestyle factors, stroke, and psychiatric comorbidities. Sensitivity analyses controlled for health care utilization.

RESULTS

During 13 years of follow-up (2.14 years on average), 507 patients (12% women) suffered a hemorrhagic stroke. The overall incidence rate was 1.70 events per 10 000-person years. In unadjusted models, PTSD was associated with an 82% greater risk of new-onset hemorrhagic stroke (hazard ratio [HR], 1.82 [95% CI, 1.48-2.24]), SSRI use was associated with a >2-fold risk (HR, 2.02 [95% CI, 1.66-2.57]), and SNRI use was associated with a 52% greater risk (HR, 1.52 [95% CI, 1.08-2.16]). In fully adjusted models, effects of PTSD and SNRI were attenuated (adjusted HR, 1.03 [95% CI, 0.81-1.34]; adjusted HR, 1.19 [95% CI, 0.83-1.71]), but SSRI use remained associated with a 45% greater risk of hemorrhagic stroke (adjusted HR, 1.45 [95% CI, 1.13-1.85]). Hypertension, drug abuse, and alcohol abuse were also associated with increased stroke risk. Nonobesity and being non-Hispanic were protective factors. In sensitivity analyses, health care utilization was a small but significant predictor of stroke.

CONCLUSIONS

In the largest known investigation of PTSD and antidepressant-associated risk for hemorrhagic stroke in young adults, use of SSRIs, but neither PTSD nor SNRIs were independently associated with incident stroke. SNRIs may be preferable for treating PTSD and comorbid conditions, although pursuing other modifiable risk factors and non-pharmacological treatments for PTSD also remains essential.

The MET(T)A Protocol: Mindfulness and EMDR Treatment Template for Agencies

Evidence indicating the relationship between trauma and substance use disorders (SUDs), in addition to relapse and treatment retention rates for this population, suggests there is a need for a trauma-focused solution to treat SUDs. Eye movement desensitization and reprocessing (EMDR) therapy has been studied extensively as an effective approach for treating trauma and Posttraumatic Stress Disorder (PTSD). The research evaluating its treatment for other mental health disorders such as SUDs is promising. Merging mindfulness and ethical mindfulness practices with EMDR therapy lends additional evidence-based elements to make the case for this integrative system of treatment to be studied as a trauma-focused primary psychotherapy to treat SUDs. The resulting treatment, the MET(T)A Protocol (Mindfulness and EMDR Treatment Template for Agencies), has been created to address the need for a trauma-focused solution to treat SUDs. Procedures of the MET(T)A Protocol as applied in each of the 8 phases of EMDR therapy are described in detail. Clinical examples are provided to explain the application of the MET(T)A Protocol.

Relationship of trauma exposure and PTSD to cigarette smoking prevalence, frequency, and quantity: Data from a nationally representative sample of U.S. adults

Individuals with Post-Traumatic Stress Disorder (PTSD) smoke cigarettes at much higher prevalences than the general population. Less is known about PTSD and other smoking behaviors (e.g., smoking quantity and frequency) or about smoking among individuals who experience trauma.

OBJECTIVE

To examine differences in cigarette smoking behaviors among adults in the United States (a) with no exposure to trauma or PTSD, (b) with trauma but no PTSD, and (c) with PTSD.

METHODS

Data came from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions-II (NESARC-II, 2004-2005) and included demographics, PTSD diagnoses, traumatic events, and smoking behaviors. Odds ratios and group differences in smoking prevalence and behaviors based on PTSD diagnoses and exposure to traumatic experiences were calculated.

RESULTS

Traumatic events and PTSD diagnoses were both associated with greater smoking prevalences than persons without trauma or PTSD. Individuals with PTSD who smoke were more likely to report daily smoking than those without PTSD who smoke (Cohen's d = 0.19). Cigarette users with either trauma or PTSD smoked more cigarettes per day than cigarette users without trauma or PTSD (Cohen's d = 0.35). US adults with trauma exposure or PTSD have higher smoking prevalences and more intense smoking behaviors than those without PTSD or trauma.

CONCLUSION

Trauma or PTSD may each serve as a clinical indicator of increased risk of cigarette smoking-related health problems and prompt the implementation of targeted interventions to reduce the harms of smoking. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Mental health problems among young people in substance abuse treatment in Sweden

BACKGROUND

Young people with substance use problems face a high risk of co-occurring mental health problems, something that may involve a more difficult life situation, social problems as well as worse treatment outcomes. The aim of this study is to analyse self-reported mental health problems among young people receiving outpatient treatment for substance use problems in Sweden. We explore what types of mental health problems are more or less predominant, and whether there are significant differences between boys and girls. In addition, we analyse how various mental health problems covary with indicators of substance abuse severity.

METHODS

The study is based on structured interviews with 1970 young people enrolled at outpatient clinics in 11 Swedish cities. The data was analysed through frequency- and averages-calculations, Chi-square tests and multivariate logistic regression analyses.

RESULTS

Self-reported mental health problems were common among the young people in the study. A relatively large percentage of the total group (34-54%) reported problems such as concentration difficulties, sleeping difficulties, anxiety and depression. At the same time, many of the young people did not report any symptoms and only a small group, about 20%, reported diagnosed mental health disorders. The results show substantial gender differences, with girls reporting significantly higher levels of mental health problems. Multivariate logistic regression analyses demonstrated significant associations between severity of drug use problems and anxiety, concentration difficulties, aggression, hallucinations and mental stress caused by experiences of trauma.

CONCLUSIONS

Treatment needs are diverse within this group of young people who use drugs. Since girls report higher levels of all mental health problems, and a larger burden of psychosocial risk factors than boys, they are likely to require more comprehensive treatment interventions. The link between more severe drug problems and mental health problems points to the importance of exploring this relationship in treatment. A multidisciplinary approach, in which co-occurring problems can be addressed simultaneously, may be the best treatment form for many young people with drug problems.

The Effectiveness of Trauma-Focused Psychodrama in the Treatment of PTSD in Inpatient Substance Abuse Treatment

This single group pretest-posttest study explores the effectiveness of trauma-focused psychodrama in the treatment of post-traumatic stress disorder (PTSD) at an inpatient addiction treatment center. The results contribute to the limited research bases of both psychodrama and PTSD treatment outcomes in inpatient addiction treatment. The present study supports the potential effectiveness of two trauma-focused psychodrama models, the Therapeutic Spiral Model and the Relational Trauma Repair Model. Findings of the research demonstrate clinically significant reductions in overall PTSD symptoms (over 25% change) and each PTSD symptom cluster (i.e., re-experiencing and intrusion, avoidance and numbing, and hyper-arousal). Additionally, patient satisfaction exit survey data support overall treatment effectiveness and highlight its tolerability, and capacity for establishing emotional safety, connection, and group cohesion. Patients even described the trauma-focused psychodrama treatment approach as enjoyable and helpful. Overall, the results of this study are promising, and support continued clinical application of trauma-focused psychodrama treatment with other subpopulations diagnosed with PTSD. However, the ability to isolate effects of trauma-focused psychodrama in this study is compromised due to the absence of a control group and participants' involvement in other inpatient treatment services.

Dual diagnosis: A systematic review of the organization of community health services

BACKGROUND

Dual diagnosis (DD), as the co-occurrence of a substance use disorder and a psychiatric disorder, is underestimated, under-diagnosed and often poorly treated throughout the world, although it is highly prevalent in people suffering from a mental disorder.

AIMS AND METHODS

This review analyzed 48 studies from a PubMed and PsycINFO databases search, in order to verify the state of the art regarding the organization of community health services for DD treatment.

RESULTS

Four macro-themes have been identified: service organization, critical issues, assessment tools and evidence-based interventions. An effective service recognizes the complexity of DD, promotes a common staff culture, and tailors the organization to local needs. The main critical issues in its implementation include the lack of specific staff training, the poor management of resources and the need for greater personalization of care plans, with attention to psychosocial interventions. Integrated service assessment tools can be used as a benchmark measure at the program level for implementation planning and at the national level to affect policy change. The integrated treatment model for DD should also aim to improve access to care and offer treatments based on scientific evidence. It is also evident that the integration of services can improve outcomes but it is not a guarantee for it.

CONCLUSION

There is an urgent need to improve networking between mental health and addiction services in order to deal with DD and create new integrated intervention models, paying attention to an approach to the whole person, seen in his/her absolute uniqueness.

Service providers' perceptions of barriers to the implementation of trauma-focused substance use services for women in Cape Town, South Africa

BACKGROUND

A substantial number of South African women with substance use disorders also report psychological trauma related to experiences of physical and sexual abuse. Trauma-focused substance use programmes may support recovery from co-occurring substance use disorders and psychological trauma, yet integrated programmes are not widely available in South Africa. As part of the process of developing a trauma-focused substance use programme for South African women, we explored service providers' views of the feasibility of implementing trauma-focused substance use interventions within usual care settings in Cape Town, including potential barriers that need to be considered when planning for implementation.

METHODS

We conducted 16 in-depth interviews with key informants responsible for planning or delivering substance use, psychological trauma or gender-based violence services to women in Cape Town. Guided by Extended Normalisation Process Theory, interviews explored participants' perceptions of the potential value of trauma-focused substance use programmes, the feasibility of their implementation, and factors that may facilitate or hinder the implementation of trauma-focused substance use programmes. Qualitative data were analysed using the framework approach.

RESULTS

Three themes emerged: (1) Potential for the implementation of trauma-focused substance use programmes, describing participants' views of the acceptability of these programmes; (2) Capacity for intersectoral collaboration, which participants considered necessary for limiting barriers to implementation; and (3) Co-operation with community structures to enhance capability for implementation.

CONCLUSION

Findings show potential for implementing trauma-focused substance use interventions in South Africa, however context-specific capacity and capability barriers need to be considered and addressed for implementation to be successful.

A meta-analysis of the effect of substance use interventions on emotion outcomes

OBJECTIVE

Emotional distress has been posited as a key underlying mechanism in the development and maintenance of substance use disorder (SUD), and patients seeking SUD treatment are often experiencing high levels of negative emotion and/or low levels of positive emotion. But the extent to which SUD interventions impact emotional outcomes among general SUD populations is yet unquantified. The current meta-analysis aims to fill this gap.

METHOD

A total of 11,754 records were screened for randomized, controlled trials examining the effect of behavioral SUD interventions on emotion outcomes. Our search yielded a total of 138 effect sizes calculated based on data from 5,146 individuals enrolled in 30 independent clinical trials. Random-effects meta-analysis was used to calculate pooled effect sizes, and metaregression analyses examined study-level moderators (e.g., intervention type).

RESULTS

Findings indicated a small but significant effect of SUD interventions on emotion outcomes, d = 0.157, 95% CI [0.052, 0.262] (k = 30). The effect size for negative emotion was nominally bigger, d = 0.162, 95% CI [0.056, 0.269] (k = 30), whereas the effect for positive emotion did not reach statistical significance, d = 0.062, 95% CI [-0.089, 0.213] (k = 7). Studies featuring SUD interventions designed to specifically target emotions (i.e., affect-regulation, mindfulness-based treatments) produced larger reductions in negative emotion compared with studies featuring interventions that did not contain specific emotion modules (e.g., contingency management).

CONCLUSIONS

Findings suggest that SUD interventions-especially mindfulness-based and affect-regulation treatments-indeed significantly reduce negative emotion, although relatively small effect sizes indicate potential room for improvement. Conclusions regarding positive emotion should be considered preliminary because of the limited numbers of samples assessing these outcomes.

A systematic review of comprehensive interventions for substance abuse: Focus on victimization

Violence victimization is common among men and women who use substances and is associated with co-occurring health issues such as PTSD, depression and HIV. Substance use interventions, therefore, should include integrated components that are designed to address co-occurring health issues among victimized substance-using individuals. This systematic review synthesized the evidence on efficacy of comprehensive, integrated, multicomponent interventions for victimized substance-using individuals. The efficacy of integrated multicomponent intervention strategies was assessed for the following syndemic conditions: mental health, substance misuse, violence, and HIV risk. Seventeen studies were identified. Examples of effective components were empowerment strategies for violence, mindfulness-based stress reduction for mental health, social cognitive skill building for addressing HIV risk and psychoeducation for substance misuse. Although in this review, some components were found to be effective, we identified methodological limitations of included studies which calls for more rigorous research in this area. Further, there is lack of evidence base for multicomponent interventions for victimized substance-using individuals in developing countries. Additional studies are needed to establish rigorous evidence base for multicomponent interventions for victimized substance using individuals that help them cope effectively with their trauma of violence and address their needs.

Do race/ethnicity and religious affiliation moderate treatment outcomes among individuals with co-occurring PTSD and substance use disorders?

The effect of race/ethnicity and religious affiliation on treatment outcomes among 107 individuals with co-occurring substance use disorder (SUD) and full or subthreshold posttraumatic stress disorder (PTSD) was examined in a secondary analysis. Participants were randomly assigned to one of three treatment conditions: dual-disorder treatment of PTSD and SUD using prolonged exposure; single-disorder relapse prevention treatment for SUD; or an active monitoring control group. Results revealed no significant interaction between race/ethnicity and treatment on PTSD and substance use frequency. However, compared to Whites, African Americans had significantly lower levels of PTSD over the course of treatment. Religious affiliation moderated the impact of treatment on substance use frequency and was a significant predictor of PTSD scores during treatment. Results highlight the need to explore factors associated with social identity variables such as race and religion that may enhance or attenuate the mechanisms of treatments for PTSD and SUD.

A systematic review and meta-analysis of group treatments for adults with symptoms associated with complex post-traumatic stress disorder

BACKGROUND

No previous meta-analyses have specifically investigated the effectiveness of psychological group therapy for symptoms associated with complex interpersonal trauma, including whether trauma memory processing (TMP) therapies are superior to psychoeducational approaches alone.

METHODS

A systematic review identified 36 randomised control trials (RCTs) which were included in the meta-analysis.

RESULTS

Large significant effect sizes were evident for TMP interventions when compared to usual care for three outcome domains including: PTSD (k = 6, g = -0.98, 95% CI -1.53, -0.43), Depression (k = 7, g = -1.12, 95% CI -2.01, -0.23) and Psychological Distress (k = 6, g = -0.98, 95% CI 1.66, -0.40). When TMP and psychoeducation interventions were directly compared, results indicated a small non-significant effect in favour of the former for PTSD symptoms, (k = 4, g = -0.34, 95% CI -1.05, 0.36) and small non-significant effect sizes in favour of the latter for Depression (k = 3, g = 0.29, 95% CI -0.83, 1.4) and Psychological Distress (k = 6, g = 0.19, 95% CI -0.34, 0.71).

LIMITATIONS

Heterogeneity and a limited number of high quality RCTs, particularly in the Substance Misuse and Dissociation domains, resulted in uncertainty regarding meta-analytical estimates and subsequent conclusions.

CONCLUSIONS

Results suggest that TMP interventions are useful for traumatic stress whereas non-TMP interventions can be useful for symptoms of general distress (e.g. anxiety and depression). Thus, both TMP and psychoeducation can be useful for the treatment of complex interpersonal trauma symptoms and further research should unravel appropriate sequencing and dose of these interventions.

A Review of Integrated Care for Concurrent Disorders: Cost Effectiveness and Clinical Outcomes

Objective: The recognition of concurrent disorders (combined mental health and substance use disorders) has increased substantially over the last three decades, leading to greater numbers of people with these diagnoses and a subsequent greater financial burden on the health care system, yet establishing effective modes of management remains a challenge. Further, there is little evidence on which to base recommendations for a particular mode of health service delivery. This paper will further summarize the existing treatment models for a comprehensive overview. The objectives of this study are to determine whether existing service models are effective in treating combined mental health and substance use disorders and to examine whether an integrated model of service delivery should be recommended to policy makers. The following two research questions are the focus of this paper: (1) Are the existing service models effective at treating mental health and substance use disorders? (2) How are existing service models effective at treating mental health and substance use disorders? Methods: We used various databases to systematically review the effectiveness of service delivery models to treat concurrent disorders. Models were considered effective if they are found to be cost-effective and significantly improve clinical and social outcomes. Results: This systematic review revealed that integrated models of care are more effective than conventional, nonintegrated models. Integrated models demonstrated superiority to standard care models through reductions in substance use disorders and improvement of mental health in patients who had diagnoses of concurrent disorders. Our meta-analysis revealed similar findings, indicating that the integrated model is more cost-effective than standard care. Conclusions: Given the limited number of studies in relation to service delivery for concurrent disorders, it is too early to make a strong evidence-based recommendation to policy makers and service providers as to the superiority of one approach over the others. However, the available evidence suggests that integrated care models for concurrent disorders are the most effective models for patient care. More research is needed, especially around the translation of research findings to policy development and, vice versa, around the translation from the policy level to the patients' level.

Integrating Treatment for Co-Occurring Mental Health Conditions

Given the high co-occurrence between alcohol use disorder (AUD) and mental health conditions (MHCs), and the increased morbidity associated with the presence of co-occurring disorders, it is important that co-occurring disorders be identified and both disorders addressed in integrated treatment. Tremendous heterogeneity exists among individuals with co-occurring conditions, and factors related to both AUD and MHCs, including symptom type and acuity, illness severity, the chronicity of symptoms, and recovery capital, should be considered when recommending treatment interventions. This article reviews the prevalence of co-occurring AUD and MHCs, screening tools to identify individuals with symptoms of AUD and MHCs, and subsequent assessment of co-occurring disorders. Types of integrated treatment and current challenges to integrate treatment for co-occurring disorders effectively are reviewed. Innovative uses of technology to improve education on co-occurring disorders and treatment delivery are also discussed. Systemic challenges exist to providing integrated treatment in all treatment settings, and continued research is needed to determine ways to improve access to treatment.

Models of Concurrent Disorder Service: Policy, Coordination, and Access to Care

Background: Societal capacity to address the service needs of persons with concurrent mental health and substance-use disorders has historically been challenging given a traditionally siloed approach to mental health and substance-use care. As different approaches to care for persons with concurrent disorders emerge, a limited understanding of current models prevails. The goal of this paper is to explore these challenges along with promising models of coordinated care across Canadian provinces. Materials and methods: A scoping review of policies, service coordination and access issues was undertaken involving a review of the formal and gray literature from 2000 to 2018. The scoping review was triangulated by an analysis of provincial auditor general reports. Results: Models of concurrent disorders service were found to have evolved unevenly. Challenges related to the implementation of models of collaborative care and local networks that foster service coordination and policy accountability were found to inhibit integrated care. Conclusion: Emergent models of coordinated care were found to include collaborative care, regional networks with centralized access to care, clinical information-sharing, cross-training, improved scope of care to include psychologists and alignment of physician incentives with patient needs to better support patient care.

Doxazosin for the treatment of co-occurring PTSD and alcohol use disorder: Design and methodology of a randomized controlled trial in military veterans

Posttraumatic stress disorder (PTSD) and alcohol use disorders (AUD) are two of the most common mental health disorders affecting civilians as well as military populations. If left untreated, individuals with co-occurring PTSD/AUD are at increased risk for developing other mental health problems (e.g., depression, anxiety), physical health problems, reduced resiliency and military readiness, and vocational and social impairment. Substantial gaps in the treatment of co-occurring PTSD/AUD exist and there is a critical need to develop more effective pharmacological treatments. The current study addresses this gap in the literature by testing the efficacy and safety of doxazosin, a long-acting and selective alpha-1 adrenergic antagonist, as compared to placebo in reducing PTSD and AUD severity among U.S. military veterans. Noradrenergic dysregulation has been implicated in the development and maintenance of PTSD and AUD, and pilot studies examining doxazosin in PTSD-only or AUD-only samples have shown promise. This is the first study, however, to evaluate doxazosin in a comorbid PTSD/AUD sample. This paper describes the rationale, design and methodology of a randomized, double-blind, placebo-controlled trial of doxazosin (16 mg/day) delivered over 12 weeks among military veterans with current PTSD and AUD. In addition, functional magnetic resonance imaging (fMRI) is applied at pre- and post-treatment to investigate the underlying pathophysiology of comorbid PTSD/AUD and identify prognostic indicators of treatment outcome. This study is designed to accelerate research on co-occurring PTSD/AUD and provide empirical evidence to inform clinical practice.

One Step at a Time: A Latent Transitional Analysis on Changes in Substance Use, Exposure to Violence, and HIV/AIDS Risk Behaviors among Female Offenders

The aim of this analysis is to identify latent subgroups of women based on substance use, exposure to violence, and risky sexual behaviors and quantify discrete stages of behavior change over time. Data comes from 317 women recruited from a Municipal Drug Court System in the Midwest. All participants were interviewed regarding their substance use and sexual behaviors, as well as their exposure to violence at baseline, a 4th-month follow-up, and an 8th-month follow-up. A latent transitional analysis (LTA), a longitudinal extension of a latent class analysis (LCA), was used to quantify discrete stages of behavior change. The results of our analyses revealed 4 distinct behavioral profiles in our sample: 1) women with high probabilities of risky sexual behaviors, exposure to violence, and crack/cocaine use, 2) women with a high probability of exposure to violence, and moderate sexual risk taking, 3) women characterized solely by a high probability of crack/cocaine use, 4) women with low probabilities of all factors. The proportion of women in latent statuses characterized by a high probability of crack/cocaine use did not substantially decrease over time. Women who experienced child sexual abuse, had a greater number of lifetime arrests, were older, and believed they had risky drug using behavior that needed changing at baseline were significantly more likely to be in higher-risk latent statuses. Targeted interventions tailored to crack/cocaine users, as well as a wide-spread need for trauma-informed interventions among females involved in the criminal justice system, are needed.

Outcomes Among Persons with HIV Following a Mental Health Admission: A Population-Based Study

To compare outcomes following psychiatric hospitalization between people with and without HIV. Population-based study of people with (n = 1,089) and without (n = 280,888) HIV who were hospitalized for psychiatric illness between January 1, 2006 and December 31, 2014. Overall, 9 (0.8%) people with HIV died within 30 days of discharge, compared with 3,710 (1.3%) HIV-negative individuals. Following multivariable adjustment, there was no difference in the risk of readmission or emergency department (ED) visits for psychiatric illness in the 90 days following discharge. Conversely, people with HIV were at higher risk of ED visits for substance use disorders and less likely to receive psychiatry follow-up during this period. HIV is associated with ED use for substance use disorders and less psychiatry follow-up within 90 days of hospital discharge for psychiatric illness. Interventions facilitating continuity of care following discharge are warranted.

Barriers to Accessing Detox Facilities, Substance Use Treatment, and Residential Services among Women Impacted by Commercial Sexual Exploitation and Trafficking

More than 50% of women entering substance use treatment in the United States reported having traded sex for money or drugs. Women's participation in addiction treatment and related services is essential to their recovery and increased safety, stabilization, and quality of life. This article's aim is to explore the barriers related to accessing detox facilities and essential services including substance use treatment and residential services for women impacted by commercial sexual exploitation (CSE). Data are drawn from a larger, community-based, grounded theory study. In-depth interview data were collected from 30 adult women who traded sex as adults (through maximum variation and snowball sampling), as well as 20 service providers who come into contact with adult women who trade sex (through nominations and purposive sampling). Finding suggest that women often encountered sobriety requirements, which created barriers to accessing addiction treatment or residential services. Some organizations' policies required evicting women if they were caught using, which created additional challenges for women who relapsed. Women wanted to avoid becoming "dopesick" on the streets or at home, which partially contributed to them needing to maintain their addiction. Consequently, some returned to sex trading, thus increasing their risk of trafficking. Some women engaged in creative strategies, such as claiming they were suicidal, in order to access the detox facilities in hospitals. Some women indicated they were only able to detox when they were forced to do so in jail or prison, often without medical assistance. Implications to improve health care delivery for this population are discussed.

Adults with Comorbid Posttraumatic Stress Disorder, Alcohol Use Disorder, and Opioid Use Disorder: The Effectiveness of Modified Prolonged Exposure

Opioid use disorders (OUDs) are a growing problem in the United States. When OUDs co-occur with problematic drinking and posttraumatic stress disorder (PTSD), negative drug-related mental and physical health outcomes may be exacerbated. Thus, it is important to establish whether PTSD treatments with established efficacy for dually diagnosed individuals also demonstrate efficacy in individuals who engage in problematic drinking and concurrent opioid misuse. Adults who met DSM-IV-TR criteria for PTSD and alcohol dependence were recruited from a substance use treatment facility and were randomly assigned to receive either modified prolonged exposure (mPE) therapy for PTSD or a non-trauma-focused comparison treatment. Compared to adults in a non-OUD comparison group (n = 74), adults with OUD (n = 52) were younger, reported more cravings for alcohol, were more likely to use amphetamines and sedatives, were hospitalized more frequently for drug- and alcohol-related problems, and suffered from more severe PTSD symptomatology, depressive symptoms, and anxiety, standardized mean differences = 0.36-1.81. For participants with OUD, mPE was associated with large reductions in PTSD symptomatology, sleep disturbances, and symptoms of anxiety and depression, ds = 1.08-2.56. Moreover, participants with OUD reported decreases in alcohol cravings that were significantly greater than those reported by the non-OUD comparison group, F(1, 71.42) = 6.37, p = .014. Overall, our findings support the efficacy of mPE for PTSD among individuals who engage in problematic drinking and concurrent opioid misuse, despite severe baseline symptoms.
