Filter by:This is a Phase II parallel group randomized controlled trial with 294 adolescents (age: 14-21 years) with alcohol and other drug [AOD] use disorder (hereafter substance use disorder), that compares two different active psychosocial interventions designed to address adolescent substance use disorder. Participants are recruited from our clinical settings and the community at two sites: one in the metro Boston, Massachusetts (MA) area and the other in the metro Farmington, Connecticut (CT), area. Study aims and hypotheses are as follows: 1. To extend the evidence for the initial efficacy of Integrated Treatment for Enhancing Growth in Recovery During Adolescence (InTEGRA), which integrates 12-Step Facilitation (TSF) with Motivational Enhancement Therapy/Cognitive Behavioral Therapy (MET/CBT) relative to gold standard MET/CBT alone (N = 294). It is hypothesized that youth assigned to InTEGRA will have greater 12-step participation during and following treatment, higher abstinence rates, and fewer substance-related negative consequences. 2. Investigate the personal recovery capital (PRC) and social recovery capital (SRC) mechanisms of behavior change through which InTEGRA may confer benefits dynamically over time (e.g., PRC: motivation, self-efficacy, coping; SRC: 12-step involvement; social network changes). 3. Investigate moderators of InTEGRA's effects on outcomes across one-year follow-up (e.g., effect of age, network support for AOD use; psychiatric severity; age composition of 12-step meetings on substance use and substance-related consequences). It is hypothesized that higher network support for AOD use, abstinence motivation, and greater AOD severity, will have a better response to InTEGRA. 4. Explore barriers and facilitators to InTEGRA adoption and implementation across providers and system administrators within the context of a type I hybrid effectiveness-implementation research design.
The purpose of this study is to compare two brief interventions targeting potentially problematic cannabis use in emerging adults (ages 18-25). Brief interventions are two 40-50 minute sessions separated by 1 week. Eligible emerging adults will complete a detailed cannabis assessment (biological and self-report), followed by one of the two brief interventions, and three follow-up assessments: one immediately after the second session and at 1- and 3-months post-intervention. Assignment to the brief intervention is random. Salivary samples will be collected at baseline, post-intervention, and both follow-ups, for a total of 4 samples, to be tested for tetrahydrocannabinol (THC) and cannabidiol (CBD).
There is a credible basis for lateral prefrontal cortex and insula deep repetitive transcranial magnetic stimulation (dTMS) stimulation as a treatment for cannabis use disorder (CUD), but no studies to date have examined this. Evidence of benefit could expand the treatment options available for CUD but require randomized controlled trials (RCTs) to evaluate its efficacy. Toward an RCT of this intervention, the proposed study is a phase 1 open-label pilot trial of dTMS for adults with CUD. This study will establish the viability of an H4 protocol constituting an active arm of a future double-blind RCT.
This study is a placebo-controlled randomized trial comparing the effects of hemp-derived cannabidiol (CBD) with and without Delta-9-tetrahydrocannabinol (THC), relative to placebo, on reducing cannabis use and cannabis use disorder (CUD) symptoms in adult treatment seeking cannabis concentrate users with CUD. Participants enroll in the study for 8 weeks (with telehealth follow-ups at 12 and 16 weeks) and are randomized to either full spectrum CBD, broad spectrum CBD, or placebo. Participants are also engaged in five weeks of psychotherapy treatment for CUD. Blood is collected to quantify investigational drug exposure and cannabis use. Participants also complete self-report measures of medical history, sleep quality, subjective cognitive function, physical activity, psychological functioning, substance use, and acute drug effects.
The prevalence of daily cannabis use and Cannabis Use Disorder (CUD) has increased in the United States over the past two decades. Brief, computerized harm reduction interventions that target specific high-risk CUD populations could be an efficient approach to reducing CUD. Distress intolerance , which refers to the tendency to negatively appraise and escape aversive emotional states, is a risk factor associated with stress-related cannabis use motivation and CUD severity/chronicity. Thus, a brief, accessible, low-cost intervention that reduces distress intolerance in those with CUD and elevated distress intolerance could have a significant public health impact. This proposed project aims to optimize an existing two-session computerized distress tolerance intervention and test its impact on distress intolerance and cannabis use outcomes in a randomized controlled trial. Specifically, the intervention will be condensed to one-session, its active ingredient bolstered, and augmented with smart phone-delivered therapy reminders. After obtaining feedback on the modified Emotional Engagement Distress Tolerance Intervention in a small sample, the intervention's efficacy compared to a stringent, credible, time-matched health education control intervention will be tested in a randomized controlled trial in 80 cannabis users with CUD and high distress intolerance. Distress intolerance, cannabis use, and psychosocial functioning outcomes will be evaluated. As an exploratory aim, a wristworn device will be used to measure objective stress responding in the real-world during the intervention period. Our central hypothesis is that, compared to a control intervention, the Emotional Engagement Distress Tolerance Intervention will produce superior reductions distress intolerance, stress-related cannabis use motivation, disordered cannabis use, and psychosocial functioning.
Cannabis is widely used worldwide and is associated with negative outcomes including cannabis use disorder (CanUD), psychosis, and cognitive impairment amongst others. Given the legalization of "recreational" and "medical" cannabis globally, the increasing availability of cannabis, the higher potency of cannabis, the availability of highly potent cannabinoid products, the commercialization of cannabis, and the rising rates of cannabis use, it is critical to understand how genetic factors influence 1) an individual's vulnerability for addiction and psychosis, 2) the response to cannabinoids, 3) the response to novel treatments for CanUD. CanUD is strongly genetically influenced; the investigators published the first CanUD genomewide association study (GWAS) with genomewide-significant results; however, the precise nature of the contribution of genetic factors in the development of CanUD is still not clear. Cannabis exposure has also been linked to a number of psychosis outcomes including schizophrenia (SCZ). SCZ is highly heritable and population-based and genetics studies both support a bidirectional genetic relationship between SCZ and CanUD. However, the precise contribution of genetic factors in the development of psychosis outcomes related to cannabis are not clear.
The goal of this clinical trial is to investigate the (cost-)effectiveness of contingency management (CM) compared with Cognitive Behavioural Therapy (CBT) for the treatment of cannabis use disorder (CUD) in youth (16-22 years). The main questions it aims to answer are: - What is the efficacy of 12 weeks outpatient CM versus CBT in youths with a CUD, in terms of cannabis abstinence during the intervention period? - What is the long-term efficacy of CM versus CBT at 6- and 12-months follow-up (FU)? - What is the cost-effectiveness of CM versus CBT at 12-months FU from a societal perspective? Study hypotheses are: 1. CM will result in more cannabis-abstinent days than CBT during the intervention; 2. CM is more effective and cost-effective than CBT at 12 months follow-up. Eligible patients (n=154) will be randomly assigned to either 12 weeks of outpatient CM or CBT. Assessments are conducted by trained research-assistants at baseline, after 6, 12, 26 and 52 weeks, and twice-weekly during treatment and consist of questionnaires, a computer task and collection of urine samples. Primary endpoint is the number of biochemically verified cannabis abstinent days in the 12-week treatment period. Key secondary endpoint: Treatment response: 50% or more reduction in cannabis use days in the past 4 weeks, compared with baseline. The primary outcome will be modelled in the intention-to-treat population in a (negative binomial) regression analysis with treatment group as independent variable and stratification variables as covariates. Cost-effectiveness and cost-utility analysis (CEA; CUA) will be performed from a societal perspective. CEA: Treatment response is the central clinical endpoint for calculations of incremental costs per responder. CUA: Incremental costs per QALY (based on EuroQoL).
This study aims to evaluate the tDCS's impact on cannabis craving in patients with schizophrenia and cannabis addiction disorder.
The purpose of this study is to investigate the safety and effectiveness of 12 weeks treatment with an extended-release injectable form of naltrexone (Vivitrol) combined with a psychological intervention in 10 treatment-seeking adults with Cannabis Use Disorder. The hypotheses are that Vivitrol combined with a psychological intervention will be well tolerated, and will reduce cannabis use, improve abstinence rates, and reduce cannabis withdrawal and craving.
Cannabis is the most widely used illicit drug and rates of hazardous use, and cannabis use disorders (CUDs), have continued to rise in recent years. The highest rates of use and CUDs are seen in young adults (20 - 24 years old) with more than 50% of young adults reporting lifetime use of cannabis, 35% report use in the past year, and 20% report use in the past month. Increased exposure produces higher risk for detrimental psychological and behavioral effects of cannabis use. Given this increased prevalence of cannabis use and associated risks, identifying effective behavioral strategies that reduce cannabis craving, negative psychological effects, and alter neurobiological mechanisms underlying problematic cannabis use are an avenue of needed research. Exercise, particularly resistance exercise, is a behavioral intervention with considerable potential as an adjunctive treatment for CUD.
