Dialectical behaviour therapy skills training for individuals with substance use disorder: A systematic review

Leclerc J. PROTOCOL: Mindfulness-based interventions for improving tic-related symptoms in children and adults with chronic tic disorder and Tourette's disorder: A systematic review

This is a protocol for a Cochrane Review (prototype). The objectives are as follows: This systematic review aims to summarize the available scientific literature on the effect of mindfulness-based approaches in children and adults with Chronic Tic Disorder (CTD) or Tourette Disorder (TD). More specifically, the research question is: What is the effectiveness of mindfulness-based interventions in reducing tic severity and improving overall functioning, quality of life, and co-occurring symptoms in children and adults with CTD or TD?

Applications and efficacy of radically open dialectical behavior therapy (RO DBT): A systematic review of the literature

Radically open dialectical behaviour therapy (RO DBT) is a transdiagnostic treatment, originally developed as a variant of dialectical behaviour therapy (DBT), that emerged as a novel treatment approach for those presenting with excessive or maladaptive overcontrol. Despite RO DBT's growing popularity among clinicians as a treatment for chronic depression, personality disorders and eating disorders, to date, no systematic review has been conducted to summarise the evidence on this therapy. Therefore, the aim of this study was to systematically review the literature to provide a current and comprehensive summary of the available evidence on the clinical applications and efficacy of RO DBT. Articles were included if they were original research studies that described the use of RO DBT in the treatment of any psychological disorder, condition or symptom, published in the English language in a peer-reviewed journal. Four electronic databases were searched, and screening, selection, risk of bias assessment and data extraction were all conducted by two independent reviewers. Fourteen articles were included in this review, including two qualitative articles, one case study, five case series studies, four quasi-experimental studies, and two articles describing one randomized control trial. Findings indicated there is emerging evidence for the use of RO DBT in both adolescents and adults, for disorders characterized by excessive self-control, such as anorexia nervosa and autism, as well as for treatment-resistant depression. While RO DBT shows promise as a treatment for disorders of overcontrol, further research is needed. This review outlines current gaps and identifies areas for future research.

Dimensional approaches to studying, assessing, and treating traumatic stress: Introduction to the Special Section

Dimensional models of psychopathology are gaining empirical support and are, thus, increasingly common in research and clinical practice. This is true for traumatic stress studies, although the movement toward dimensional conceptualizations of traumatic stress may be somewhat slower, perhaps due at least in part to how trauma is diagnosed. The purpose of this special section is to collect and showcase cutting-edge basic, applied, and conceptual work on dimensional models of traumatic stress. Its goal is to highlight the utility of such models and to facilitate greater connection between traumatic stress studies and the broader dimensional movement in psychopathology.

Psychotherapies in opioid use disorder: toward a step-care model

Opioid use disorder (OUD) is characterized by a lack of control in opioid use, resulting in psychological distress and deficits in interpersonal and social functioning. OUD is often associated with psychiatric comorbidities that increase the severity of the disorder. The consequences of OUD are dramatic in terms of increased morbi-mortality. Specific medications and psychotherapies are essential tools not only in the treatment of OUD but also in the prevention of suicide and overdoses. In our review, we assess the different types of psychotherapies (counseling, motivational interviewing, contingency management, cognitive-behavioral therapy, and dialectical-behavior therapy) that are delivered to opioid users, either associated or un-associated with OUD medications and/or medications for psychiatric disabilities. We describe the application of these therapies first to adult opioid users and then to adolescents. This work led us to propose a stepped-care model of psychotherapies for OUD which provided information to assist clinicians in decision-making regarding the selection of psychotherapeutic strategies according to patients' OUD severity.

Context matters: Exploring the adaptive nature of self-regulation skills in predicting abstinence among veterans with alcohol use disorder

BACKGROUND

Alcohol use disorder (AUD) is highly prevalent among veterans in the United States. Self-regulation skills (e.g., coping and emotion regulation) are important biopsychosocial factors for preventing relapse. However, how variation in self-regulation skills supports abstinence based on contextual demands is understudied in veterans with AUD.

METHODS

In a prospective longitudinal design, treatment-seeking veterans (n = 120; 29 females) aged 23-91 with AUD completed the Alcohol Abstinence Self-Efficacy Scale to assess temptation to drink across several high-risk situations (i.e., negative affect, social/positive emotions, physical concerns, and craving/urges) as well as the Brief-COPE and Emotion Regulation Questionnaire to assess self-regulation skills. Abstinence status was assessed at 6 months. T-tests were used to identify self-regulation skills that differed between abstinent and non-abstinent individuals. Multivariate regression with model selection was performed using all possible interactions between each high-risk situation and the self-regulation skills that significantly differed between groups.

RESULTS

Overall, 33.3% of participants (n = 40; nine females) were abstinent at 6 months. Abstinent individuals reported significantly higher use of suppression (p = 0.015), acceptance (p = 0.005), and planning (p = 0.045). Multivariate regression identified significant interactions between (1) planning and physical concerns (p = 0.010) and (2) acceptance, suppression, and craving/urges (p = 0.007). Greater planning predicted abstinence in participants with higher temptation to drink due to physical concerns (e.g., pain). For individuals with lower temptation to drink due to cravings/urges, simultaneous higher suppression and acceptance increased the likelihood of abstinence. Conversely, for participants with higher cravings, greater acceptance with lower suppression was linked to a higher probability of abstinence.

CONCLUSIONS

Results suggest that the adaptiveness of self-regulation skills in predicting AUD recovery is dependent on contextual demands and highlight the need for culturally sensitive treatments. Collectively, these findings indicate that further research on coping and regulatory flexibility may be an important avenue for tailoring AUD treatment for veterans.

Adverse Childhood Experiences and Problematic Cannabis Use: The Role of Emotion Dysregulation and Affective Impulsivity

Problematic cannabis use is highly prevalent among postsecondary students. Consequently, there is a need to examine risk factors associated with problematic cannabis use in this population. The present study investigated whether emotion dysregulation mediates the relationship between adverse childhood experiences (ACEs) and problematic cannabis use, and whether affective impulsivity (negative and positive urgency) uniquely moderates this relationship. Participants consisted of current cannabis users (N = 586) recruited from five universities across Canada. Participants completed an online survey containing self-report measures of ACEs, emotion dysregulation, negative and positive urgency, and problematic cannabis use. Among the sample of postsecondary students, 36% (n = 213) met the threshold for problematic cannabis use. Moderated-mediation analyses revealed that ACEs were positively associated with emotion dysregulation and problematic cannabis use. There was also a significant indirect effect of emotion dysregulation on the association between ACEs and problematic cannabis use at moderate and high (but not low) levels of negative urgency, and at moderate and high (but not low) levels of positive urgency. The moderated-mediation models remained significant when controlling for other facets of impulsivity. Results suggest that elevated levels of emotion dysregulation and urgency are important proximal risk factors for problematic cannabis use among postsecondary students with a history of ACEs. While ACEs cannot be modified given their occurrence in the past, interventions that aim to build mindfulness and adaptive emotion regulation skills may be beneficial for reducing the likelihood that these students will engage in impulsive behaviors, such as cannabis use, when experiencing emotional distress.

Feasibility, Acceptability, and Potential Efficacy of a Self-Guided Internet-Delivered Dialectical Behavior Therapy Intervention for Substance Use Disorders: Randomized Controlled Trial

BACKGROUND

People with alcohol and substance use disorders (SUDs) often have underlying difficulties in regulating emotions. Although dialectical behavioral therapy is effective for SUDs, it is often difficult to access. Self-guided, internet-delivered dialectical behavioral therapy (iDBT) allows for expanded availability, but few studies have rigorously evaluated it in individuals with SUDs.

OBJECTIVE

This study examines the feasibility, acceptability, and potential efficacy of an iDBT intervention in treatment-seeking adults with SUDs. We hypothesized that iDBT would be feasible, credible, acceptable, and engaging to people with SUDs. We also hypothesized that the immediate versus delayed iDBT group would show comparatively greater improvements and that both groups would show significant improvements over time.

METHODS

A 12-week, single-blinded, parallel-arm, randomized controlled trial was implemented, with assessments at baseline and at 4 (acute), 8, and 12 weeks (follow-up). A total of 72 community adults aged 18 to 64 years were randomized. The immediate group (n=38) received access to iDBT at baseline, and the delayed group (n=34) received access after 4 weeks. The intervention (Pocket Skills 2.0) was a self-guided iDBT via a website, with immediate access to all content, additional text and email reminders, and additional support meetings as requested. Our primary outcome was substance dependence, with secondary outcomes pertaining to feasibility, clinical outcomes, functional disability, and emotion dysregulation, among other measures. All outcomes were assessed using self-report questionnaires.

RESULTS

iDBT was perceived as a credible and acceptable treatment. In terms of feasibility, 94% (68/72) of the participants started iDBT, 13% (9/68) were early dropouts, 35% (24/68) used it for the recommended 8 days in the first month, and 50% (34/68) were still active 4 weeks later. On average, the participants used iDBT for 2 hours and 24 minutes across 10 separate days. In the acute period, no greater benefit was found for the immediate group on substance dependence, although we did find lower depression (b=-2.46; P=.02) and anxiety (b=-2.22; P=.02). At follow-up, there were greater benefits in terms of reduced alcohol (b=-2.00; P=.02) and nonalcoholic substance (b=-3.74; P=.01) consumption in the immediate access group. Both groups demonstrated improvements in substance dependence in the acute (b=-1.73; P<.001) and follow-up period (b=-2.09; P<.001). At follow-up, both groups reported reduced depression, anxiety, suicidal behaviors, emotional dysregulation, and functional disability.

CONCLUSIONS

iDBT is a feasible and acceptable intervention for patients with SUDs, although methods for improving engagement are warranted. Although results did not support efficacy for the primary outcome at 4 weeks, findings support reductions in substance dependence and other mental health concerns at 12 weeks. Notwithstanding the limitations of this study, the results suggest the potential value of iDBT in the treatment of SUDs and other mental health conditions.

Feasibility and Efficacy of Intensive Dialectical Behavior Therapy Skills Training in An Outpatient Setting for A Group of Patients with Extensive Care Needs - A Transdiagnostic Approach

PURPOSE

Dialectical behavior therapy (DBT) is a treatment originally developed för chronically suicidal adults. It is common to adapt it by using one specific component, the DBT skills training (DBT-ST) and apply it in a group therapy setting for a variety of mental disorders. The primary aim of the study was to explore whether patients with extended care needs would report improved mental health after participating in an intensive form of DBT-ST. The secondary aim was to explore whether the use of psychiatric inpatient care for the group would decrease.

METHODS

Thirty-seven participants completed the Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM), and visual analogue scale (VAS) at three time points: pre-intervention, post-intervention and at 6-month follow-up after intensive DBT-ST.

RESULTS

One-way ANOVA showed a significant effect for time on the CORE-OM: F (2,35) = 7.93, p = .001, η2 = 0.312 (large effect size). Post hoc tests indicated a significant difference between pre-intervention and post-intervention (p = .001) and between pre-intervention and follow-up (p = .01). A Friedman test indicated a statistically significant difference in the VAS scale scores across the three time points, with p-values between 0.00 and 0.05. There was no difference in psychiatric healthcare consumption.

CONCLUSION

These study results confirm to some extent the feasibility and effectiveness of the intensive DBT-ST in a transdiagnostic clinical setting. The participants had a positive outcome from the skills training program, but psychiatric healthcare consumption did not decrease.

Latent patterns of sleep disturbance, pain impact, and depressive symptoms in residential substance use treatment

AIM

Sleep disturbance, clinically significant pain, and depressive symptoms commonly occur together among individuals with substance use disorders. The purposes of the present study were to 1) identify subgroups of individuals with heterogenous patterns of pain, sleep disturbance, and depressive symptoms, and 2) identify demographic and clinical correlates of profile membership.

MATERIAL AND METHODS

The present study assessed a sample (N = 8621) of individuals seeking residential substance use treatment in 2020 and 2021 in the United States. We examined whether unique sub-groups could be identified based on patterns of sleep disturbance, pain impact, and depressive symptoms during the first four weeks of treatment, using longitudinal latent profile analysis. Next, we explored demographic, substance use, and clinical correlates (i.e., distress intolerance) of profile membership, as well as whether profile membership was associated with treatment attrition.

RESULTS

The identified classes were: 1) Low sleep disturbance, pain impact, and depressive symptoms, 2) High pain, remitting depressive symptoms, and mild sleep disturbance, 3) High depressive symptoms, low pain, and remitting sleep disturbance, and 4) High sleep disturbance, pain impact, and depressive symptoms. Individuals with high pain, depressive symptoms, and sleep disturbance were more likely to be older, use opioids as their primary substance, have high distress intolerance, and discontinue treatment.

CONCLUSION

Results highlight the importance of comprehensive care and management of physical health conditions, particularly among older adults. Further, results highlight that distress intolerance may be a modifiable risk factor for co-occurring sleep disturbance, pain impact, and depressive symptoms.

Predictive impact of different acute cannabis intoxication effects with regard to abstinence motivation and cessation of use

Cannabis use is a common risk factor for psychoses. But although prevalence of consumption as well as potency of cannabis increased, the incidence of schizophrenia remained stable. The discontinuation hypothesis suggests that a potential increase of psychoses incidence may be relativized by more frequent cessation of consumption due to higher rates of adverse psychosis-like intoxication effects (PLE), caused by stronger cannabis. A mixed methods online survey was administered to 441 current and past users to analyze the predictive impact of different acute intoxication effects regarding abstinence motivation/cessation of use. Our hypothesis was that PLE would be experienced as the most aversive intoxication effect and therefore have the highest predictive significance. Possible confounds were included (craving, patterns of consumption and sociodemographics). Further analyzes compared past versus current users regarding the quality of intoxication effects, suggesting that past users retrospectively experienced more unpleasant experiences than current users. Free-text data explored subjective reasons for abstinence. We found that paranoid/dysphoric intoxication effects were most predictive for abstinence motivation. Less predictive were psychosis-like intoxication effects such as hallucinations. Group comparisons revealed significant more unpleasurable and less positive intoxication effects in past users compared with current users. Current users with the intention to stop consumption showed significantly more paranoia/dysphoria intoxication compared to users with no intention to stop use. As a conclusion, different intoxication experiences have different effects on abstinence motivation and substance use behavior. They therefore provide a focus that should be increasingly integrated into treatment concepts.

Psychiatric symptoms, current use of tobacco, alcohol, illicit drug, and poly-substance among medical students in Eastern Turkey

The study aims to investigate the prevalence and patterns of substance use among medical students and to examine associated psychiatric symptoms. It has been observed that depression and psychoticism scores have a significant effect on smoking, and interpersonal sensitivity-hostility-paranoid ideation scores have a significant effect on drinking. It has been shown that interpersonal sensitivity and depression scores are more predictive of mono-and poly-substance use. Revealing the relationship between tobacco, alcohol, poly-substance use, and psychiatric symptoms in the medical school sample shows the importance of practices aimed at increasing students' awareness of their psychiatric symptoms and providing access to psychiatric services.

The mediating role of tolerance for psychological pain in the relationship of childhood trauma to suicidal ideation in individuals with a substance use disorder

OBJECTIVES

The association between childhood trauma and suicidal ideation has been well documented in several populations, including individuals with a substance use disorder (SUD). However, a gap still exists in the literature regarding the mechanisms by which childhood trauma later impacts suicide risk. This cross-sectional study tested the effect of childhood trauma on suicidal ideation, as well as the mediating effect of tolerance for psychological pain (managing the pain and enduring the pain) in that relationship, controlling for the effect of depressive symptoms, in individuals with a SUD.

METHODS

A sample of 102 adults with a SUD participated in the study. Path analysis by structural equation␣modelling tested a mediation model.

RESULTS

Depressive symptoms and lower levels of managing the pain were found to fully mediate the association between childhood trauma and suicidal ideation.

CONCLUSIONS

Our results suggest that depressive symptoms and a lack of ability to manage psychological pain contribute towards explaining why traumatic childhood experiences may result in suicidal cognitions in individuals with SUDs. Moreover, they have relevant implications for prevention and clinical interventions regarding suicidal ideation in this population.

PRACTITIONER POINTS

Childhood trauma relates to suicidal ideation in individuals with a substance use disorder. Depressive symptoms contribute towards explaining why traumatic childhood experiences may result in suicidal cognitions. A lack of ability to manage psychological pain also contributes towards explaining this relationship. The obtained results have relevant implications for the prevention of and clinical intervention for suicidal ideation in SUD individuals.
