Cognitive behavioral therapy for substance use disorders

The effectiveness of an indicated prevention programme for substance use in individuals with mild intellectual disabilities and borderline intellectual functioning: results of a quasi-experimental study

AIMS

To assess the effectiveness of Take it personal!, a prevention programme for individuals with mild intellectual disabilities and borderline intellectual functioning (MID-BIF) and substance use (SU). The prevention programme aims to reduce SU (alcohol, cannabis and illicit drugs) among experimental to problematic substance users.

DESIGN

A quasi-experimental design with two arms and a 3-month follow-up.

SETTING

Adolescents were recruited from 14 treatment centres in the Netherlands specialized in offering intra- and extramural care for people with MID-BIF and behavioural problems.

PARTICIPANTS

Data were collected from 66 individuals with MID-BIF assigned either to the intervention condition (n = 34) or to the control condition (n = 32).

INTERVENTIONS

Take it personal! was designed to target four personality traits: sensation-seeking, impulsive behaviour, anxiety sensitivity and negative thinking. For each of these profiles, interventions were developed that were structurally the same but contained different personality-specific materials, games and exercises. The control group received care as usual.

MEASUREMENTS

Primary outcomes at 3-month follow-up were frequency of SU, severity of SU and binge drinking.

RESULTS

Results showed intervention effects for SU frequency (F(1, 50.43)  = 9.27, P = 0.004) and binge drinking (F(1, 48.02)  = 8.63, P = 0.005), but not for severity of SU (F(1, 42.09)  = 2.20, P = 0.145).

CONCLUSIONS

A prevention programme to reduce substance use among experimental to problematic users with mild intellectual disabilities and borderline intellectual functioning helped participants to decrease substance use frequency and binge drinking.

Adolescent Gender Identity, Sexual Orientation, and Cannabis Use: Potential Mediations by Internalizing Disorder Risk

BACKGROUND/AIMS

Adolescents who identify as nonbinary gender or as not heterosexual report higher levels of mental illness than their counterparts. Cannabis use is a commonly employed strategy to cope with mental illness symptoms among adolescents; however, cannabis use can have many deleterious health consequences for youth. Within the frame of minority stress theory, this study investigates the relationships between gender identity and sexual orientation, internalizing disorder symptoms, and cannabis use among adolescents.

METHOD

A national cross-sectional survey of a generalizable sample of high school students in Canada from the 2017 wave (N = 15,191) of the Cancer Risk Assessment in Youth Survey was analyzed in spring 2019. Mediation analyses were completed to examine risk of internalizing disorder symptoms as a potential mediator of the association between (1) gender identity and (2) sexual orientation, and cannabis use.

RESULTS

Indirect effects in all models show significantly higher levels of reported internalizing disorder symptoms for female (OR = 3.44, 95% CI [2.84, 4.18]) and nonbinary gender (OR = 3.75, 95% CI [2.16, 6.51]) compared with male students. Sexual minority adolescents had higher odds of internalizing disorder risk relative to non-sexual minority adolescents (OR = 3.13, 95% CI [2.63, 3.74]). Students who reported higher rates of internalizing disorder symptoms were more likely to have ever used cannabis. Patterns of partial mediation are also present among all groups.

DISCUSSION/CONCLUSIONS

Findings can be used to better inform mental health interventions for adolescents. Future study should explore specific mental health stressors of vulnerable adolescent groups with respect to cannabis use as a coping mechanism.

Sources of prescription opioids and tranquilizers for misuse among U.S. young adults: differences between high school dropouts and graduates and associations with adverse outcomes

Background and Objectives: Prior research has identified that sources of prescription drugs for misuse vary based on educational attainment, which is important as certain sources are associated with adverse outcomes. The current research addressed limitations of the extant literature by creating distinct categories of push factors for high school dropout (e.g., negative school performance/experiences), pull factors for high school dropout (e.g., starting a family or getting a job), and high school graduates who did not attend college.Methods: Using data from the 2009-2014 National Survey on Drug Use and Health, prevalence of sources were estimated and design-based multivariable logistic regression investigated the association between sources and educational attainment. Additionally, multivariable logistic regression assessed the associations between sources and adverse outcomes (i.e., substance use, substance use disorders, and mental health) separately for each educational category.Results: College respondents were more likely to report "physician" and free from "friend/relative" and less likely to report "purchased" as sources. For most educational categories, "purchasing" prescription drugs was associated with adverse outcomes. Additionally, "theft/fake" prescription emerged as a source associated with adverse outcomes for college respondents, while "friend/relative" was associated with adverse outcomes for high school graduates that did not go on to college.Conclusions: This research has important clinical implications as it identified young adults with a college education as being less likely to obtain prescription drugs from sources known to be associated with adverse outcomes. It also highlighted how associations between sources and adverse outcomes vary based on educational attainment.

An Integrated Model of Nature and Nurture Factors that Contribute to Addiction and Recovery

BACKGROUND

In the context of the opioid epidemic and growing awareness of addiction as a public health concern, there are efforts to inform the public, patients, families, and policy makers about the factors that contribute to addiction and facilitate recovery. Several theoretical models provide useful frameworks for this discussion, but each of them has limitations.

OBJECTIVES

This paper presents an accessible yet comprehensive theoretical model that integrates empirical evidence about addiction etiology and recovery using the nature-nurture paradigm.

RESULTS

The model presents substance use along a continuum, and identifies risk and protective factors in multiple domains that have been identified by research. The domains on the nature side of the model include genetic and biological factors, comorbid psychiatric and medical disorders, physiological reinforcement of substance use, and changes to neural mechanisms. The domains on the nurture side of the model include sociocultural factors, environmental factors, personality, emotions, cognitions, psychological reinforcement of substance use, and cognitive and behavioral changes. The progression from increased or decreased substance use to addiction or recovery is mediated by changes in neural mechanisms and cognitive and behavioral changes, which have feedback loops with the physiological and psychological reinforcement.Conclusions/Importance: This model is a useful heuristic, consistent with a public health framework, for discussing addiction and recovery with patients, their families, and the public. This integrated model of nature and nurture factors has the potential to inform clinical practice, consultation, research, prevention programs, educational programs, and public policy.

A Deep Learning Algorithm to Predict Hazardous Drinkers and the Severity of Alcohol-Related Problems Using K-NHANES

Purpose: The number of patients with alcohol-related problems is steadily increasing. A large-scale survey of alcohol-related problems has been conducted. However, studies that predict hazardous drinkers and identify which factors contribute to the prediction are limited. Thus, the purpose of this study was to predict hazardous drinkers and the severity of alcohol-related problems of patients using a deep learning algorithm based on a large-scale survey data. Materials and Methods: Datasets of National Health and Nutrition Examination Survey of South Korea (K-NHANES), a nationally representative survey for the entire South Korean population, were used to train deep learning and conventional machine learning algorithms. Datasets from 69,187 and 45,672 participants were used to predict hazardous drinkers and the severity of alcohol-related problems, respectively. Based on the degree of contribution of each variable to deep learning, it was possible to determine which variable contributed significantly to the prediction of hazardous drinkers. Results: Deep learning showed the higher performance than conventional machine learning algorithms. It predicted hazardous drinkers with an AUC (Area under the receiver operating characteristic curve) of 0.870 (Logistic regression: 0.858, Linear SVM: 0.849, Random forest classifier: 0.810, K-nearest neighbors: 0.740). Among 325 variables for predicting hazardous drinkers, energy intake was a factor showing the greatest contribution to the prediction, followed by carbohydrate intake. Participants were classified into Zone I, Zone II, Zone III, and Zone IV based on the degree of alcohol-related problems, showing AUCs of 0.881, 0.774, 0.853, and 0.879, respectively. Conclusion: Hazardous drinking groups could be effectively predicted and individuals could be classified according to the degree of alcohol-related problems using a deep learning algorithm. This algorithm could be used to screen people who need treatment for alcohol-related problems among the general population or hospital visitors.

The role of glutamate mGlu5 and adenosine A2a receptor interactions in regulating working memory performance and persistent cocaine seeking in rats

Cocaine use disorder (CUD) is associated with neurobehavioral deficits that are resistant to current treatments. While craving and high rates of relapse are prominent features of CUD, persistent cognitive impairments are common and linked to poorer treatment outcomes. Here we sought to develop an animal model to study post-cocaine changes in drug seeking and working memory, and to evaluate 'therapeutic' effects of combined glutamate mGlu5 and adenosine A2a receptor blockade. As mGlu5 antagonists reduce drug seeking, and A2a blockade ameliorates working memory impairment, we hypothesized that mGlu5 + A2a antagonist cocktail would reduce both cocaine relapse and post-cocaine working memory deficits. Adult male Sprague-Dawley rats were first trained and tested in an operant delayed match-to-sample (DMS) task to establish the working memory baseline, followed by 6 days of limited and 12 days of extended access cocaine self-administration. Chronic cocaine reduced working memory performance (abstinence day 30-40) and produced robust time-dependent cocaine seeking at 45-, but not 120-days of abstinence. Systemic administration of A2a antagonist KW-6002 (0.125 and 1 mg/kg) failed to rescue post-cocaine working memory deficit. It also failed to reverse working memory impairment produced by mGlu5 NAM MTEP (1 mg/kg). Finally, KW-6002 prevented the ability of MTEP to reduce cocaine seeking and increased locomotor behavior. Thus, despite mGlu5 and A2a being exclusively co-localized in the striatum and showing behavioral synergism towards reducing cocaine effects in some studies, our findings advocate against the use of mGlu5 + A2a antagonist cocktail as it may further compromise cognitive deficits and augment drug craving in CUD.

Risk Factors, Pathogenesis, and Strategies for Hepatocellular Carcinoma Prevention: Emphasis on Secondary Prevention and Its Translational Challenges

Hepatocellular carcinoma (HCC) is a leading cause of cancer-associated mortality globally. Given the limited therapeutic efficacy in advanced HCC, prevention of HCC carcinogenesis could serve as an effective strategy. Patients with chronic fibrosis due to viral or metabolic etiologies are at a high risk of developing HCC. Primary prevention seeks to eliminate cancer predisposing risk factors while tertiary prevention aims to prevent HCC recurrence. Secondary prevention targets patients with baseline chronic liver disease. Various epidemiological and experimental studies have identified candidates for secondary prevention-both etiology-specific and generic prevention strategies-including statins, aspirin, and anti-diabetic drugs. The introduction of multi-cell based omics analysis along with better characterization of the hepatic microenvironment will further facilitate the identification of targets for prevention. In this review, we will summarize HCC risk factors, pathogenesis, and discuss strategies of HCC prevention. We will focus on secondary prevention and also discuss current challenges in translating experimental work into clinical practice.

The Preponderance of Psychic Elements in Drug Addiction

The clinical perspective used to understand a patient with an addiction affects the course of treatment and the possibilities for recovery. Positivist and pharmacological models have become popular in the treatment of addictions. These models claim that addiction is primarily a pharmacological occurrence and privilege the biochemical effects of specific substances over the intrapsychic conflict of the patient in order to justify the phenomenology of addiction. Although psychoanalytic approaches have been previously used to treat addictive patients, they have frequently been considered unsuitable and inadequate for such cases. The author's purpose is to use the scope that psychoanalytic comprehension provides to examine the subject who is addicted in relation to his or her maturational development; considering the roles played by pleasure, ego defects, and defensive behavior, derived from case vignettes, in order to illustrate the role of intrapsychic life in the maintaining of an addiction.

Objective analysis of language use in cognitive-behavioral therapy: associations with symptom change in adults with co-occurring substance use disorders and posttraumatic stress

Substance use disorders (SUD) commonly co-occur with posttraumatic stress disorder (PTSD) symptoms, and the comorbidity is prevalent and difficult-to-treat. Few studies have objectively analyzed language use in psychotherapy as a predictor of treatment outcomes. We conducted a secondary analysis of patient language use during cognitive-behavioral therapy (CBT) in a randomized clinical trial, comparing a novel, integrated CBT for PTSD/SUD with standard CBT for SUD. Participants included 37 treatment-seeking, predominantly African-American adults with SUD and at least four symptoms of PTSD. We analyzed transcripts of a single, matched session across both treatment conditions, using the Linguistic Inquiry and Word Count (LIWC) program. The program measures language use across multiple categories. Compared to standard CBT for SUD, patients in the novel, integrated CBT for PTSD/SUD used more negative emotion words, partially consistent with our hypothesis, but less positive emotion words. Further, exploratory analyses indicated an association between usage of cognitive processing words and clinician-observed reduction in PTSD symptoms, regardless of treatment condition. Our results suggest that language use during therapy may provide a window into mechanisms active in therapy.

An ecological momentary assessment of mood, coping and alcohol use among emerging adults in psychiatric treatment

Background: Emerging adulthood is a critical period for the onset of both mental health disorders and problematic alcohol use. Coping strategies can play an important role in mitigating the onset and progression of these conditions in emerging adulthood. The current study examined daily mood, coping strategy use, and alcohol use during an individualized, ecological momentary intervention (EMI).Objectives: To examine the within-person relationship between mood, coping strategy use, and alcohol use.Methods: Emerging adults (N = 20, 55% female) in a partial hospital program for anxiety or mood disorders who endorsed drinking to cope completed a 6-week EMI to increase non-substance coping skills. The study also measured mood, coping strategy use, and alcohol use over the course of the intervention.Results: Mood and coping variables did not predict the likelihood of drinking on a given day. On drinking days, the number of pre-consumption coping strategies were related to reduced alcohol use (p =.02) and there was a significant interaction between negative mood and coping in predicting alcohol use (p <.01). When pre-consumption negative mood was high, coping strategies predicted decreased alcohol use (p =.02), but when negative mood was low, this relationship was nonsignificant.Conclusions: Using coping skills was associated with reduced alcohol use on days when negative mood was high. Increasing non-substance coping skills may help emerging adults reduce their alcohol use in response to negative mood.

Evidence on Virtual Reality-Based Therapies for Psychiatric Disorders: Meta-Review of Meta-Analyses

Background

Among all diseases globally, mental illnesses are one of the major causes of burden. As many people are resistant to conventional evidence-based treatments, there is an unmet need for the implementation of novel mental health treatments. Efforts to increase the effectiveness and benefits of evidence-based psychotherapy in psychiatry have led to the emergence of virtual reality (VR)–based interventions. These interventions have shown a wide range of advantages over conventional psychotherapies. Currently, VR-based interventions have been developed mainly for anxiety-related disorders; however, they are also used for developmental disorders, severe mental disorders, and neurocognitive disorders.

Objective

This meta-review aims to summarize the current state of evidence on the efficacy of VR-based interventions for various psychiatric disorders by evaluating the quality of evidence provided by meta-analytical studies.

Methods

A systematic search was performed using the following electronic databases: PubMed, PsycINFO, Web of Science, and Google Scholar (any time until February 2020). Meta-analyses were included as long as they quantitatively examined the efficacy of VR-based interventions for symptoms of a psychiatric disorder. To avoid overlap among meta-analyses, for each subanalysis included within this meta-review, only one analysis provided from one meta-analysis was selected based on the best quality of evidence.

Results

The search retrieved 11 eligible meta-analyses. The quality of evidence varied from very low to moderate quality. Several reasons account for the lower quality evidence, such as a limited number of randomized controlled trials, lack of follow-up analysis or control group, and the presence of heterogeneity and publication bias. Nonetheless, evidence has shown that VR-based interventions for anxiety-related disorders display overall medium-to-large effects when compared with inactive controls but no significant difference when compared with standard evidence-based approaches. Preliminary data have highlighted that such effects appear to be sustained in time, and subjects may fare better than active controls. Neurocognitive disorders also appear to improve with VR-based approaches, with small effects being found for various clinical outcomes (eg, cognition, emotion). Finally, there are insufficient data to classify VR-based interventions as an evidence-based practice for social skills training in neurodevelopmental disorders and compliance among patients with schizophrenia.

Conclusions

VR provides unlimited opportunities by tailoring approaches to specific complex problems and individualizing the intervention. However, VR-based interventions have not shown superiority compared with usual evidence-based treatments. Future VR-based interventions should focus on developing innovative approaches for complex and treatment-resistant symptoms that are difficult to address with traditional treatments. Future research should also aim to gain a better understanding of the potential factors that may mediate VR outcomes to improve treatment.

Intensive longitudinal methods for studying the role of self-regulation strategies in substance use behavior change

Purpose of review

Many psychosocial interventions for substance use disorders (SUDs) focus on teaching self-regulation strategies. Research using intensive longitudinal methods (ILM), such as ecological momentary assessment and daily diaries, is critical for elucidating if and how these strategies function as mechanisms of change among individuals with SUDs. We review this emerging area of research.

Recent findings

We found a small number of studies using ILM to study self-regulation strategies in SUD (n=18 studies), with most conducted among college student drinkers (n=9) and cigarette smokers (n=7), and few among treatment-engaged individuals, and those with other drug use disorders. There is preliminary evidence that the use of specific self-regulation strategies commonly taught in psychosocial interventions for SUDs (i.e., cognitive reappraisal, problem solving, stimulus control, harm reduction) is associated with decreased momentary or daily substance use, at the within-person level.

Summary

There is a need for further ILM research on self-regulation strategies as mechanisms of substance use behavior change. Such research can inform the development, refinement, and personalization of interventions that teach self-regulation strategies, including mobile interventions that facilitate strategy use in the moment. One key next step is developing psychometrically validated ILM assessments of self-regulation strategy use.

Acceptability and efficacy of naltrexone for criminal justice-involved individuals with opioid use disorder: a systematic review and meta-analysis

BACKGROUND AND AIMS

Criminal justice-involved individuals carry a disproportionately higher burden of opioid use disorder (OUD) than those not involved with the criminal justice system, and are often unable to access opioid agonist therapies such as methadone and buprenorphine. The opioid receptor antagonist naltrexone (NTX) is effective for the prevention of relapse to OUD and may be more acceptable in criminal justice settings. The objectives of this review were to: (1) provide an overall summary effect across studies for the efficacy and acceptability of oral and injectable NTX for the treatment of OUD among criminal justice-involved individuals and (2) examine systematic variations in study results to explain heterogeneity among study-specific effects.

METHODS

Systematic review and meta-analysis of 1045 patients across 11 studies (10 randomized controlled trials, one quasi-experimental study). All available outcomes were pooled using random-effects meta-analysis. Subgroup analyses were conducted for oral and injectable naltrexone; meta-regression analyses were conducted for socio-demographic and study-level characteristics.

RESULTS

NTX improved retention in treatment [risk ratio (RR) = 1.31; 95% confidence interval (CI) = 1.05, 1.63], reduced rates of re-incarceration (RR = 0.70, 95% CI = 0.54-0.92), reduced opioid relapse (RR = 0.63, 95% CI = 0.53-0.76) and improved opioid abstinence (RR = 1.38, 95% CI = 1.16-1.65). While NTX was associated with a greater burden of adverse events overall (RR = 1.49, 95% CI = 1.13-1.95), the findings were inconclusive as to whether or not a difference was present for the number of serious adverse events or overdoses.

CONCLUSIONS

Naltrexone appears to be efficacious and acceptable for the treatment of opioid use disorder among criminal justice-involved individuals; however, the risk for adverse events must be weighed against the potential benefits.

Strategies to improve treatment utilization for substance use disorders: A systematic review of intervention studies

BACKGROUND

Many people who need specialty treatment for substance use disorders (SUDs) do not receive it. Clinical interventions could increase treatment utilization but are not routinely used. This systematic review aimed to describe clinical interventions that may increase SUD specialty treatment utilization (i.e., treatment initiation, attendance, meaningful engagement) and to determine which intervention(s) most consistently increase treatment utilization.

METHODS

We conducted a systematic review of clinical intervention studies (published in English between 2000 and 2017) reporting outcomes relevant to specialty SUD treatment utilization. Outcomes were treatment initiation, attendance, and meaningful engagement. Risk of bias was assessed using Cochrane guidelines and randomized controlled trials (RCTs) with bias scores < 3 were included in a synthesis of results. Proportions of positive to negative utilization outcomes were calculated for each low-bias RCT; studies with 50% positive outcomes or more were considered "majority-positive". Studies were categorized by theory-based approach.

RESULTS

Twenty-three RCTs had low risk of bias and were synthesized. Among intervention types with two or more studies, cognitive-behavioral (100% majority-positive) and coordinated care (67% majority-positive) interventions were most likely to increase treatment initiation, while 12-step promotion interventions were most likely to increase treatment attendance (50% majority-positive). One study (12-step promotion) measured meaningful engagement, with majority-positive outcomes.

CONCLUSIONS

A systematic review and narrative synthesis of clinical interventions promoting specialty SUD treatment utilization provided preliminary evidence that cognitive-behavioral and coordinated care interventions may increase treatment initiation, while 12-step promotion interventions may promote treatment attendance. More quality studies and greater consistency in treatment utilization measurement are needed.

CE: Opioid Use Disorder: Pathophysiology, Assessment, and Effective Interventions

Opioid use disorder (OUD) is a chronic, relapsing disease. Genetic variability, dysregulated stress system response, and history of opioid experimentation or escalating exposure all contribute to the likelihood of developing OUD, which produces complex brain changes that make it difficult to stop opioid use. Understanding the neurobiology of OUD helps nurses anticipate the behaviors of patients with OUD and approach them with empathy. Here, the authors discuss the pathophysiology of OUD, available screening tools, medical treatments, and behavioral interventions that have demonstrated efficacy in reducing substance use.

Virtual Nature as an Intervention for Reducing Stress and Improving Mood in People with Substance Use Disorder

Substance use disorder (SUD) afflicts a large percentage of the United States population, with negative implications that cost more than $420 billion annually. This population often experiences negative emotions throughout the recovery process, including anxiety, depression, stress, and negative affect. Currently, evidence-based treatment strategies for SUD include cognitive behavioral therapy, motivational interviewing, 12-step programs, and mindfulness-based treatment. One intervention that has not been studied at length among individuals with SUD is use of the natural environment as treatment. Among other patient populations, nature has been shown to reduce stress and anxiety by regulating autonomic nervous system function, reducing symptoms of depression, and improving mood. The purpose of this study was to investigate whether viewing nature videos could similarly reduce stress and improve mood in individuals with SUD. A crossover design was used to compare viewing a nature scene and practicing mindfulness-based activities for women with SUD at a residential treatment facility. Over four weeks, participants engaged in the two activities for the first 10 minutes of their daily program. Immediately before and after each 10 minute session, measures were taken for heart rate, in beats per minute (BPM); affect, using the Positive and Negative Affect Scale (PANAS); and overall mood, using a 10-point rating scale from "very unpleasant" to "pleasant." Thirty-six women completed the study. For viewing a nature scene and practicing the mindfulness-based activities, there were statistically significant reductions in mean negative affect scores (p=0.001) and heart rate (p ≤ 0.001). In addition, for participants in both conditions, overall mood improved significantly (p=0.030). The results from this study provide initial evidence that viewing nature has similar benefits to MBT in the treatment of stress and negative mood associated with the SUD recovery process and may be an additional, cost-effective treatment strategy for individuals with SUD.

Combination Therapy and Opioids: Effectiveness of Transcranial Direct-Current Stimulation (tDCS) and Emotion Regulation Training in Reducing Current Drug Craving

Background and objectives: Craving is the main symptom of addiction that is accompanied by dependence and relapse. The present study was aimed to compare the effectiveness of combined Transcranial Direct-Current Stimulation (tDCS) and emotion regulation training with that of separate tDCS and emotion regulation training in reducing current drug craving and thoughts and fantasies about drug use. Materials and methodology: This was a quasi-experimental study with a pretest-posttest design and three intervention groups. The statistical population included all patients dependent on opioids in medium-term residential drug rehabilitation centers in Zahedan, Iran, in 2018-2019. From eight randomly selected centers, a total of 54 patients were selected based on inclusion and exclusion criteria, and randomly divided into three intervention groups. Data were gathered using the Personal Drug Use Questionnaire, Desires for Drug Questionnaire (DDQ), and Drug Use Thoughts, Fantasies, and Temptations Questionnaire. All analyses were performed using SPSS-16. Results: The Kruskal-Wallis test indicated significant differences between the three intervention groups in current drug craving and thoughts and fantasies about drug use (P ..001). In addition, examination of the mean rank showed that t significant decrease was higher for the combined tDCS and emotion regulation training group. Conclusion: Addiction is very similar to other chronic disorders. Therefore, combined (integrated) therapies can have a very important role in treating addiction, especially in relapse prevention.

Considering Drug-Associated Contexts in Substance Use Disorders and Treatment Development

Environmental contexts that are reliably associated with the use of pharmacologically active substances are hypothesized to contribute to substance use disorders. In this review, we provide an updated summary of parallel preclinical and human studies that support this hypothesis. Research conducted in rats shows that environmental contexts that are reliably paired with drug use can renew extinguished drug-seeking behavior and amplify responding elicited by discrete, drug-predictive cues. Akin to drug-associated contexts, interoceptive drug stimuli produced by the psychopharmacological effects of drugs can also influence learning and memory processes that play a role in substance use disorders. Findings from human laboratory studies show that drug-associated contexts, including social stimuli, can have profound effects on cue reactivity, drug use, and drug-related cognitive expectancies. This translationally relevant research supports the idea that treatments for substance use disorders could be improved by considering drug-associated contexts as a factor in treatment interventions. We conclude this review with ideas for how to integrate drug-associated contexts into treatment-oriented research based on 4 approaches: pharmacology, brain stimulation, mindfulness-based relapse prevention, and cognitive behavioral group therapy. Throughout, we focus on alcohol- and tobacco-related research, which are two of the most prevalent and commonly misused drugs worldwide for which there are known treatments.

Identifying Risk Factors Associated With Postoperative Infection Following Elective Lower-Extremity Total Joint Arthroplasty

This article addresses the importance of identifying risk factors associated with postoperative infection following elective lower-extremity total joint arthroplasty. Specifically, this review discusses risk factors recognized by the American Academy of Orthopaedic Surgeons that should be carefully considered and assessed by the orthopaedic team in collaboration with the primary care provider before proceeding with surgery.

Learning to lose control: A process-based account of behavioral addiction

Learning psycho(bio)logy has developed a solid corpus of evidence and theory regarding behavior control modes. The present article briefly reviews that literature and its influence on recent models in which the transition from goal-directed to compulsive behavior is identified as the main process underlying substance use disorders. This literature is also relevant to non-substance addictive disorders, and serves as basis to propose a restricted definition of behavioral addiction relying on the presence of behavior-specific compulsivity. Complementarily, we consider whether some activities can become disordered while remaining mostly goal-driven. Based on reinforcement learning models, relative outcome utility computation is proposed as an alternative mechanism through which dysfunctional behaviors (even not qualifying as addictive) can override adaptive ones, causing functional impairment. Beyond issues of conceptual delimitation, recommendations are made regarding the importance of identifying individual etiological pathways to dysregulated behavior, the necessity of accurately profiling at-risk individuals, and the potential hazards of symptom-based diagnosis. In our view, the validity of these recommendations does not depend on the position one takes in the nosological debate.

Development of the Highly Processed Food Withdrawal Scale for Children

INTRODUCTION

Highly processed foods (with added fats and/or refined carbohydrates) may trigger an addictive-like process, including withdrawal when these foods are reduced. Withdrawal is marked by affective, cognitive, and physical symptoms that may hinder dietary change. A recently developed scale of highly processed food withdrawal in adults (ProWS) provides evidence for this construct. Children commonly consume highly processed foods, but no measures currently exist to examine highly processed food withdrawal in children. The purpose of this study was to develop a measure (ProWS-C) to assess for signs of highly processed food withdrawal in children.

METHODS

Parents who had recently attempted to reduce their child's highly processed food consumption were recruited through an online crowdsourcing platform. 304 parents (56.9% mothers) reported on their 3-11-year-old children (63.8% male). The ProWS-C was designed to reflect parents' observations of child behavior. Internal consistency and validity were evaluated using the Dimensional Yale Food Addiction Scale Version 2.0 for Children (dYFAS-C 2.0.), Children's Food Neophobia Scale-Modified (CFNS), and body mass index (BMI) silhouettes.

RESULTS

Exploratory factor analysis revealed a one-factor structure with 21 items (α = 0.94). The ProWS-C demonstrated convergent validity with more child food addiction symptoms (r = 0.55, p < 0.001) and higher child BMI (r = 0.24, p < 0.001) and discriminant validity with child food neophobia (r = -0.10, p = 0.08). The ProWS-C was associated with less success in reducing child highly processed food intake independent of child addictive-like eating and BMI (p = 0.001).

DISCUSSION

The ProWS-C provides preliminary evidence for highly processed food withdrawal in children and appears to be a psychometrically sound tool for assessing parent-reported withdrawal symptoms in children. Illuminating specific challenges families face when reducing highly processed foods may improve parents' ability to help their children make sustainable dietary changes.

Brief group-delivered motivational interviewing is equally effective as brief group-delivered cognitive-behavioral therapy at reducing alcohol use in risky college drinkers

College students are particularly vulnerable to risky alcohol use, which increases their likelihood of developing an alcohol use disorder in the future. As such, preventing and reducing alcohol use among college students should be a priority for health and social policies. This work was aimed to show that brief group-delivered MI is as effective as brief-group CBT at reducing alcohol use in college students. Eighty-nine college students (69 females; mean age = 21.01, SD = 2.85) with risky alcohol use, as measured by the AUDIT-C, were assigned to two groups, receiving three sessions of either brief group-delivered MI or CBT (bMI/bCBT). Alcohol use was assessed 3 and 6 months after the interventions, and analyzed according to an Intention-to-treat design. Changes in alcohol use at both points (relative to baseline) as well as post-intervention scores of intention to continue treatment and satisfaction with the psychologist were compared across groups, using one-sided Bayesian t-tests. Alcohol use decreased in both groups at the 3- and 6-months measurement points (relative to baseline). However, using bCBT superiority as an alternative hypothesis and the absence of such superiority as a point-null hypothesis, the Bayes factors supported the null at both the 3- and the 6-months follow-up (BF₀₁ = 7.13, and BF₀₁ = 5.22 respectively). Furthermore, the intention to continue treatment was substantially higher in the bMI group (BF10 = 9.77). These results are considerably robust to changes in analyses’ priors. This study suggests that bCBT is not more effective than bMI at reducing alcohol use in our college student group (in which females are overrepresented). Additionally, bMI showed higher intention to continue treatment scores. The comparable results of brief and group-delivered CBT and MI interventions in alcohol use reduction allows clinicians to select treatments based on their own skills or preferences without any detriment to efficacy.

Change & Grow® Therapeutic Model for Addiction: Preliminary Results of an Interventional Study

The last years have seen a paradigm shift concerning addictive disorders, indicating the necessity to study alternative therapeutic models. In this longitudinal study, the objective was to explore the impact of the Change & Grow^® therapeutic model developed and used by VillaRamadas on certain psychological variables that frequently appear associated with addiction. A repeated measures (first and last weeks of treatment) design was used, and the psychological measurements were Beck’s Depression Inventory II (BDI-II), Suicide Ideation Questionnaire (SIQ), State-Trait Anxiety Inventory (STAI), and Montreal Cognitive Assessment (MoCA). Results include 26 (16 male and 10 female) patients. Age varied between 17 and 64 years (M = 35.62, SD = 12.60) and duration of treatment between 91 and 193 days (M = 147.35, SD = 27.05). The MoCA total result was significantly higher in the last week of treatment. The results of BDI-II, SIQ, and STAI (both state and trait) were all significantly lower. Neither duration of treatment nor self-reported motivation presented significant correlation values with the difference between measures for any of the variables. The Change & Grow^® therapeutic model appears to have an impact on relevant psychological variables in patients admitted into treatment for addictive disorders.

Concordance of Self- and Partner-Reported Alcohol Consumption Among Couples Experiencing Intimate Partner Violence in Zambia

BACKGROUND

Hazardous alcohol use is a predictor of intimate partner violence (IPV), and both are increasingly prevalent in sub-Saharan Africa. The accurate measurement of alcohol consumption is therefore critical in IPV intervention studies that target hazardous drinking. Collecting a collateral report in addition to self-report is one convergent validity approach to improve alcohol measurement. We investigated concordance between self- and partner-reported alcohol use among women who reported recent IPV and their male partners in Zambia.

METHODS

Data were from the baseline of a randomized IPV intervention trial of 247 heterosexual couples in which a woman has reported recent IPV and her male partner has recent hazardous alcohol use. Both partners completed the Alcohol Use Disorders Identification Test (AUDIT) in reference to their own drinking and in reference to their partner's drinking. We calculated percent agreement across a range of outcomes: any use, quantity, frequency, and hazardous use. We also compared self- and partner-reported AUDIT scores using t-tests.

RESULTS

Concordance was poor across most outcomes. Percent agreement with respect to the women's drinking ranged from 60% to 65% across outcomes and with respect to the men's drinking from 51% to 89%. Women's average partner-reported AUDIT score (20.7) was statistically significantly (p < 0.0001) higher than men's average self-reported score (15.8).

CONCLUSIONS

In contrast to collateral report studies conducted in the United States, concordance between self- and partner-reported alcohol consumption was poor among families experiencing IPV in Zambia. Given the possible biases associated with self-reported alcohol use, findings suggest that a convergent validity approach is useful in this research context.

Prevention, screening, and treatment for heavy drinking and alcohol use disorder

Heavy drinking and alcohol use disorder are major public health problems. Practitioners not specialising in alcohol treatment are often unaware of the guidelines for preventing, identifying, and treating heavy drinking and alcohol use disorder. However, a consensus exists that clinically useful and valuable tools are available to address these issues. Here, we review existing information and developments from the past 5 years in these areas. We also include information on heavy drinking and alcohol use disorder among individuals with co-occurring psychiatric disorders, including drug use disorders. Areas covered include prevention; screening, brief intervention, and referral for treatment; evidence-based behavioural interventions; medication-assisted treatment; technology-based interventions (eHealth and mHealth); and population-level interventions. We also discuss the key topics for future research.

Alcohol Use Disorders in Adolescents

Alcohol use during adolescence is an important and modifiable health risk behavior given the significant acute consequences and long-term impacts on the developing brain. Alcohol is the most common substance used by young adults 12 to 17 years old, with binge drinking, polysubstance use, and co-occurring mental health disorders posing particular concerns in this age group. Physicians can play a crucial role in screening and responding to alcohol use, with targeted brief interventions designed to delay or decrease use.

Comorbidity of opioid-related and anxiety-related symptoms and disorders

Opioid use disorder and anxiety disorders co-occur at strikingly high rates, and this comorbidity is marked by a more severe clinical presentation and poorer prognosis for treatment. Given the substantial morbidity and mortality associated with these two disorders, it is imperative to understand factors related to the high rates of co-occurrence in order to inform the development of specialized treatments for this population. Several lines of study suggest that simultaneously addressing opioid-related and anxiety-related symptoms and processes, particularly intolerance of distress and pain-related anxiety, may yield improved outcomes for this high risk, vulnerable population. Future work is needed to identify other novel mechanisms as well as develop specialized treatments to augment standard medication-assisted treatment.

Increased neural activity in the right dorsolateral prefrontal cortex during a risky decision-making task is associated with cocaine use in methadone-maintained patients

BACKGROUND

Methadone maintenance is an effective treatment for opioid use disorder (OUD), yet many methadone-maintained patients (MMPs) struggle with cocaine use during OUD recovery. The current study aimed to identify whether prefrontal cortex (PFC) activity during a risky decision-making task was associated with cocaine use during a 90-day follow-up in MMPs.

METHODS

MMPs (N = 28) attended a single neuroimaging session wherein PFC activity was measured using functional near-infrared spectroscopy (fNIRS) during the Balloon Analogue Risk Task (BART). Trait impulsivity was assessed via the Barratt Impulsiveness Scale version 11 (BIS-11). Following the neuroimaging session, MMPs were tracked via electronic health records for 90 days to determine treatment outcomes including cocaine use verified by urine drug screens.

RESULTS

During the BART, MMPs who used cocaine displayed increased neural activity in the right PFC during active decision-making (F1, 22 = 14.75, p = 0.001) and the right dorsolateral PFC during active minus passive decision-making (F1, 22 = 5.56, p = 0.028) compared to participants who did not use cocaine. Receiver operating characteristic curves confirmed that neural activity in the right PFC during active decision-making (AUC = 0.841, 95% CI, 0.697-0.985, p = 002), and in the right dorsolateral PFC during active minus passive decision-making (AUC = 0.805, 95% CI, 0.643-0.968, p = 0.006) was associated with continued cocaine use. MMPs who used cocaine versus those who did not reported increased trait impulsivity on the BIS-11 Total Score (t=-2.28, p = 0.031).

CONCLUSIONS

The fNIRS device is portable, relatively easy to use, and potentially feasible for use in methadone outpatient programs to assess propensity for negative treatment outcomes such as continued cocaine use.

Dissemination of cognitive behavioral therapy for substance use disorders in the Department of Veterans Affairs Health Care System: Description and evaluation of Veteran outcomes

BACKGROUND

As part of the nation's largest dissemination and implementation of evidence-based psychotherapies (EBPs) and the promotion of EBPs for substance use disorders (SUDs), the Veterans Health Administration (VHA) is working to nationally implement Cognitive Behavioral Therapy for SUD (CBT-SUD). The current manuscript describes the approach to system-wide training and reports Veteran outcomes associated with CBT-SUD implementation. Methods: Four-hundred fifty-eight Veterans with a range of treatment goals received treatment through the Department of Veterans Affairs (VA) CBT-SUD Training Program. Veteran outcomes related to substance use, substance use-related problems, and quality of life were assessed with the Brief Addiction Monitor, the Short Inventory of Problems, and the World Health Organization Quality of Life-BREF. Results: Statistically significant reductions in alcohol use, heavy alcohol use, other drug use, and substance use-related problems, as well as significant improvements in quality of life, were observed over the course of treatment. Conclusions: Program evaluation findings suggest that large-scale training in and implementation of EBPs for SUDs is associated with improvements in substance use and other functional outcomes. Limitations from this real-world implementation project, including the lack of a control group and missing post-treatment data, are discussed.

A meta-analysis of cognitive-behavioral therapy for alcohol or other drug use disorders: Treatment efficacy by contrast condition

OBJECTIVE

This meta-analysis examined 30 randomized controlled trials (32 study sites; 35 study arms) that tested the efficacy of cognitive-behavioral therapy (CBT) for alcohol or other drug use disorders. The study aim was to provide estimates of efficacy against three levels of experimental contrast (i.e., minimal [k = 5]; nonspecific therapy [k = 11]; specific therapy [k = 19]) for consumption frequency and quantity outcomes at early (1 to 6 months [kes = 41]) and late (8+ months [kes = 26]) follow-up time points. When pooled effect sizes were statistically heterogeneous, study-level moderators were examined.

METHOD

The inverse-variance weighted effect size was calculated for each study and pooled under random effects assumptions. Sensitivity analyses included tests of heterogeneity, study influence, and publication bias.

RESULTS

CBT in contrast to minimal treatment showed a moderate and significant effect size that was consistent across outcome type and follow-up. When CBT was contrasted with a nonspecific therapy or treatment as usual, treatment effect was statistically significant for consumption frequency and quantity at early, but not late, follow-up. CBT effects in contrast to a specific therapy were consistently nonsignificant across outcomes and follow-up time points. Of 10 pooled effect sizes examined, two showed moderate heterogeneity, but multivariate analyses revealed few systematic predictors of between-study variance.

CONCLUSIONS

The current meta-analysis shows that CBT is more effective than a no treatment, minimal treatment, or nonspecific control. Consistent with findings on other evidence-based therapies, CBT did not show superior efficacy in contrast to another specific modality. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Transcranial Direct Current Stimulation on Opium Craving, Depression, and Anxiety: A Preliminary Study

OBJECTIVES

Transcranial direct current stimulation can be effective in reducing the craving for food, alcohol, and methamphetamine. Because its effects have not been tested on patients with opium use disorder, we investigated its efficacy when it is combined with a standard methadone maintenance therapy protocol.

METHODS

We carried out a pretest-posttest control group method to evaluate the effect of transcranial direct current stimulation at the dorsolateral prefrontal cortex (right anodal/left cathodal) on opium craving, depression, and anxiety symptoms. We considered opium craving as a primary outcome as well as depression and anxiety symptoms as secondary outcomes. Sixty participants with opium use disorder were randomly assigned into 3 groups (n = 20 for each group): (1) an active transcranial direct current stimulation with methadone maintenance treatment (active tDCS group), (2) sham transcranial direct current stimulation with methadone maintenance treatment (sham tDCS group), and (3) only methadone maintenance treatment (methadone maintenance treatment group). All participants completed the Desire for Drug Questionnaire, Obsessive-Compulsive Drug Use Scale, Beck Depression Inventory II, and Beck Anxiety Inventory a week before and a week after the treatment. The outcomes were assessed by independent assessors who were blind to the treatment conditions.

RESULTS

The active tDCS group had a significant reduction in opium craving, depression, and anxiety symptoms compared with the other 2 groups.

CONCLUSIONS

Our results provide a preliminary support for using the transcranial direct current stimulation along with methadone maintenance therapy in the treatment of patients with opium use disorder.

An initial randomized controlled trial of behavioral activation for treatment of concurrent crystal methamphetamine dependence and sexual risk for HIV acquisition among men who have sex with men

Men who have sex with men (MSM) continue to be the largest risk group for HIV infections in the U.S., where crystal methamphetamine abuse heightens risk for HIV infection through greater engagement in condomless anal sex (CAS). Existing treatments lack attention to replacement activities or the role of depressed mood. Behavioral activation (BA) is an evidence-based approach for depression that involves identifying and participating in pleasurable, goal-directed activities. We hypothesize, for MSM abusing crystal methamphetamine, re-learning how to engage in non-drug-using aspects of life would facilitate their ability to benefit from sexual risk reduction (SRR) counseling. Project IMPACT was a pilot randomized-controlled-trial. Forty-six MSM at sexual risk of acquiring HIV who met DSM-IV criteria for crystal methamphetamine dependence were enrolled. Of those MSM, 41 were randomized: 21 were assigned to the intervention, two sessions of SRR, ten sessions of BA with SRR, and one session of relapse prevention; 20 participants were assigned to a control condition (two sessions of SRR). At the acute post-intervention visit, intervention participants reported an average of 3.2 CAS acts with men who were HIV-infected or whose status they did not know, compared to 4.5 among control participants (β = -0.36; 95% CI: -0.69, -0.02; p = 0.035). At the 6-month post-intervention visit, intervention participants reported 1.1 CAS acts with men who were HIV-infected or whose status they did not know compared to 2.8 among control participants (β = -0.95; 95% CI: -1.44, -0.46; p < 0.0001). Similarly, intervention participants reported 1.0 CAS acts under the influence of crystal methamphetamine with men who were HIV-infected or whose status they did not know compared to 2.5 among control participants (β = -0.87; 95% CI: -1.38, -0.36; p = 0.0005). Lastly, intervention participants reported more continuous days abstaining from crystal methamphetamine compared to control (50.1 vs. 39.0, respectively) (β = 0.25; 95% CI: 0.16, 0.34; p < 0.0001). Findings are encouraging, provide evidence of feasibility and acceptability, and demonstrate initial efficacy for reducing sexual risk for HIV and crystal methamphetamine use.

Craving in Opioid Use Disorder: From Neurobiology to Clinical Practice

Opioid use disorder (OUD) is a major public health issue that has reached epidemic levels in some parts of the world. It is a chronic and complex neurobiological disease associated with frequent relapse to drug taking. Craving, defined as an overwhelmingly strong desire or need to use a drug, is a central component of OUD and other substance use disorders. In this review, we describe the neurobiological and neuroendocrine pathways that underpin craving in OUD and also focus on the importance of assessing and treating craving in clinical practice. Craving is strongly associated with patients returning to opioid misuse and is therefore an important treatment target to reduce the risk of relapse and improve patients' quality of life. Opioid agonist therapies (OAT), such as buprenorphine and methadone, can significantly reduce craving and relapse risk, and it is essential that patients are treated optimally with these therapies. There is also evidence to support the benefits of non-pharmacological approaches, such as cognitive behavioral therapy and mindfulness-based interventions, as supplementary treatments to opioid agonist therapies. However, despite the positive impact of these treatments on craving, many OUD patients continue to suffer with negative affect and dysphoria. There is a clear need for further studies to progress our understanding of the neurobiological basis of craving and addiction and to identify novel therapeutic strategies as well as to optimize the use of existing treatments to improve outcomes for the growing numbers of patients affected by OUD.

Alcoholic Hepatitis: A Review

Alcoholic liver disease (ALD) represents a spectrum of injury, ranging from simple steatosis to alcoholic hepatitis to cirrhosis. Regular alcohol use results in fatty changes in the liver which can develop into inflammation, fibrosis and ultimately cirrhosis with continued, excessive drinking. Alcoholic hepatitis (AH) is an acute hepatic inflammation associated with significant morbidity and mortality that can occur in patients with steatosis or underlying cirrhosis. The pathogenesis of ALD is multifactorial and in addition to genetic factors, alcohol-induced hepatocyte damage, reactive oxygen species, gut-derived microbial components result in steatosis and inflammatory cell (macrophage and neutrophil leukocyte) recruitment and activation in the liver. Continued alcohol and pro-inflammatory cytokines induce stellate cell activation and result in progressive fibrosis. Other than cessation of alcohol use, medical therapy of AH is limited to prednisolone in a subset of patients. Given the high mortality of AH and the progressive nature of ALD, there is a major need for new therapeutic intervention for this underserved patient population.

Improved Patient Outcomes and Reduced Wait Times: Transforming a VA Outpatient Substance Use Disorder Program

Systematic evaluation and redesign of a substance use disorder treatment program resulted in elimination of wait times, same-day treatment, and increased pharmacotherapy for patients with alcohol and opioid use disorders.

Mental health and substance use in HIV-infected adolescents

PURPOSE OF REVIEW

Adolescents with HIV include both those infected perinatally and behaviourally. This population is confronted by normative challenges and HIV stressors as they move towards becoming increasingly independent adults. This review focuses on mental health and substance use in adolescents with HIV. These are important issues in their own right as well as having implications for antiretroviral therapy (ART) adherence and HIV management.

RECENT FINDINGS

Sixteen articles, published from 1 January 2016 to 1 September 2017, were included from 13 distinct studies, mostly from the United States and Africa. Cross-sectional designs predominated. There was only one intervention study. There was evidence of mental health and substance use difficulties, although not at a higher level than comparison groups. Consistent associations were found between ART nonadherence and both mental health difficulties and substance use; environmental stressors and mental health difficulties.

SUMMARY

Adolescents with HIV display considerable resilience. There is a need, however, for interventions for mental health difficulties and substance use, and for ART adherence interventions to consider these issues. Studies on mental health and substance use should cover a wider range of regions. Mitigating the impact and reducing exposure to environmental stressors is a priority.

Group Prenatal Care for Women Receiving Medication-Assisted Treatment for Opioid Use Disorder in Pregnancy: An Interprofessional Approach

Opioid use disorder among pregnant women is common and rapidly increasing nationwide. Group prenatal care is an innovative alternative to individual care for pregnant women and has been shown to improve women's and health care providers' satisfaction and adherence to care. We describe a novel group prenatal care program colocated in an opioid treatment program that integrates prenatal care, substance use disorder counseling, and medication-assisted treatment. Our interprofessional model draws on the unique contributions of physicians, midwives, nurses, and mental health professionals to address the complex needs of pregnant women with opioid use disorder. Participants reported increased trust and engagement with health care providers and peers, improved prenatal care and birth experience, and increased resilience for relapse prevention. Group prenatal care is an accepted and promising model for women with opioid use disorder in pregnancy and has the potential to improve outcomes for women and newborns.

An evaluation of the maintenance to abstinence (MTA) program in achieving abstinence in opioid users and improving mental health and quality of life

BACKGROUND

Residential opioid rehabilitation aims to improve the mental health and quality of life of opioid users through abstinence and residential program participation. This study aimed to determine the depression, anxiety, stress and quality of life amongst maintenance to abstinence (MTA) program residents. Secondary study aims were to assess the personal characteristics of MTA clients, addiction and risk taking behaviours, factors associated with program completion, as well as to assess the reliable change in participants' mental health and quality of life on exit.

METHODS

Retrospective analysis of routinely collected data (2013-2017) from surveys completed by 100 clients. Outcome measures were: Depression, Anxiety, Stress Score (DASS-42), World Health Organisation Quality of Life 8 questions (WHOQOL-8) and Kessler Psychological Distress Scale (K10). Other variables included demographics, drug use, other addictions, aggression, self-harm, suicidal ideation/attempts, and risk taking behaviours. Statistical methods included Chi-square, Fisher's exact, t-tests, repeated measures analysis of variance and the Reliable Change Index.

RESULTS

All mean DASS-42, WHOQOL-8 and K10 scores improved significantly in all participants from entry to exit (p < 0.001). The majority of participants demonstrated reliable improvement across all psychometric measures. Completion rates for the MTA program were 51%. Depression (p = 0.023), anxiety (p = 0.010) and stress (p = 0.015) DASS-42 scores decreased significantly more in completers compared to non-completers. The rate of improvement in mean WHOQOL-8 scores and psychological distress scores (K10) was not statistically significantly different between completers and non-completers over time. There was no significant difference between completers and non-completers on socio-demographics, self-reported drug addiction or risk taking behaviour on program entry, except for suicidal thoughts while intoxicated (p = 0.033). Completers were more satisfied with their relationships (p = 0.044) and living place (p = 0.040) on program entry.

CONCLUSION

Overall, completers and non-completers demonstrated improved mental health and quality of life from entry to exit, regardless of program completion. Depression, anxiety and stress reduced more markedly in program completers. Policy makers and programmers could use these findings to further validate their own programs to improve mental health and quality of life of opioid users.

Preliminary development of a neuroimaging paradigm to examine neural correlates of relationship conflict

Social stress in the form of conflict between romantic partners is a salient correlate of substance use disorders (SUD), and also plays an integral role in SUD treatment outcomes. Neuroimaging has advanced the study of social stress on SUD etiology, course, and treatment. However, no neuroimaging paradigms have yet been developed to examine neural responses to conflict among romantic couples. In order to fill this gap in the literature, the goal of this exploratory study was to examine the preliminary feasibility of a novel relationship conflict fMRI paradigm. We compared the effects of an auditory relationship conflict versus a neutral cue on functional connectivity in corticolimbic brain regions, and the associations between neural activities and self-report ratings of relationship adjustment, substance use problems, and intimate partner violence. We also explored sex differences in neural correlates of relationship conflict versus neutral cues. Participants demonstrated increased functional connectivity between the amygdala and the prefrontal cortex during the relationship conflict cue compared to the neutral cue. Intimate partner violence was associated with functional connectivity. Sex differences emerged in neural responses to the relationship conflict cue compared to the neutral cue. Collectively, the findings demonstrate preliminary validity of this novel neuroimaging paradigm for couples.

Group treatment for substance use disorder in adults: A systematic review and meta-analysis of randomized-controlled trials

BACKGROUND AND AIMS

From residential programs to outpatient services, group therapy permeates the clinical field of substance misuse. While several group interventions for substance use disorders (SUDs) have demonstrated effectiveness, the existing evidence on group therapy has not been systematically reviewed. The current meta-analysis aims to provide estimates of the efficacy of group therapy for SUDs in adults using rigorous methods.

METHODS

We included studies comparing group psychotherapy to no treatment control groups, individual psychotherapy, medication, self-help groups, and other active treatments applying no specific psychotherapeutic techniques for patients with substance use disorder. The primary outcome was abstinence, and the secondary outcomes were frequency of substance use and symptoms of substance use disorder, anxiety, depression, general psychopathology, and attrition. A comprehensive search was conducted in Medline, Web of Science, CENTRAL, and PsycINFO, complemented by a manual search. Random-effects meta-analyses were run separately for different types of control groups.

RESULTS

Thirty-three studies were included. Significant small effects of group therapy were found on abstinence compared to no treatment, individual therapy, and other treatments. Effects on substance use frequency and SUD symptoms were not significant, but significant moderately sized effects emerged for mental state when group therapy was compared to no treatment. There were no differences in abstinence rates between group therapy and control groups. These results were robust in sensitivity analyses and there was no indication of publication bias.

CONCLUSIONS

The current findings represent the best available summary analysis of group therapy for SUDs in adults, however cautious interpretation is warranted given the limitations of the available data.

A randomized clinical trial of the Recovery Line among methadone treatment patients with ongoing illicit drug use

BACKGROUND

Relapse, drug use, and treatment dropout are common challenges facing patients receiving methadone. Though effective, multiple barriers to face-to-face counseling exist. The Recovery Line (RL), an automated, self-management system based on Cognitive Behavioral Therapy, is a phone-based adjunctive treatment that provides low cost, consistent delivery and immediate therapeutic availability 24 h a day.

METHODS

The current study was a 12-week randomized clinical efficacy trial of treatment-as-usual (TAU) only or RL + TAU for methadone treatment patients with continued illicit drug use (N = 82). Previous small trial phases evaluated methods to increase participant engagement and use of the RL and were incorporated into the current RL version. Primary outcomes were days of self-reported illicit drug abstinence and urine screens negative for illicit drugs.

RESULTS

Days of self-reported illicit drug abstinence improved for patients in RL + TAU but not in TAU. Percent of urine screens negative for illicit drugs, coping skills efficacy, and retention in methadone treatment did not differ by condition. Patients in RL + TAU attended more substance use disorder treatment and self-help group sessions during treatment than those in TAU. RL system use was generally low and more system use was correlated with abstinence outcomes.

CONCLUSIONS

Although the RL did not impact urine screen outcomes, it increases self-reported abstinence. Additional methods to increase patient engagement with automated, self-management systems for substance use disorder are needed.

A Smartphone Attention Bias Intervention for Individuals With Addictive Disorders: Protocol for a Feasibility Study

Background

Substance use disorders are highly prevalent globally. Relapse rates following conventional psychological interventions for substance use disorders remain high. Recent reviews have highlighted attentional and approach or avoidance biases to be responsible for multiple relapses. Other studies have reported the efficacy of interventions to modify biases. With advances in technologies, there are now mobile versions of conventional bias modification interventions. However, to date, no study has evaluated bias modification in a substance-using, non-Western sample. Existing evaluations of mobile technologies for the delivery of bias interventions are also limited to alcohol or tobacco use disorders.

Objective

This study aims to examine the feasibility of mobile-based attention bias modification intervention among treatment-seeking individuals with substance use and alcohol use disorders.

Methods

This is a feasibility study, in which inpatients who are in their rehabilitation phase of clinical management will be recruited. On each day that they are in the study, they will be required to complete a craving visual analogue scale and undertake both a visual probe-based assessment and and modification task in a smartphone app . Reaction time data will be collated for the computation of baseline attentional biases and to determine whether there is a reduction of attentional bias across the interventions. Feasibility will be determined by the number of participants recruited and participants’ adherence to the planned interventions up until the completion of their rehabilitation program and by the ability of the app in detecting baseline biases and changes in biases. Acceptability of the intervention will be assessed by a short questionnaire of users’ perceptions of the intervention. Statistical analyses will be performed using SPSS version 22.0, while qualitative analysis of the perspectives will be performed using NVivo version 10.0.

Results

This study was approved by the National Healthcare Group Domain Specific Research Board, with approval number (2018/00316). Results will be disseminated by means of conferences and publications.Currently, we are in the process of recruitment for this study.

Conclusions

To the best of our knowledge, this is the first study to evaluate the feasibility and acceptability of a mobile attention bias modification intervention for individuals with substance use disorders. The data pertaining to the feasibility and acceptability are undoubtedly crucial because they imply the potential use of mobile technologies in retraining attentional biases among inpatients admitted for medical-assisted detoxification and rehabilitation. Participants’ feedback pertaining to the ease of use, interactivity, and motivation to continue using the app is crucial because it will determine whether a codesign approach might be warranted to design an app that is acceptable for participants and that participants themselves would be motivated to use.
