Filter by:Chronic cannabis consumption has been associated with poor psychosocial functioning that could be associated to cerebellar dysfunction. The cerebellum has a relevant role in adaptation processes and has a high density of cannabinoid 1 receptor (CB1R). Implicit motor learning is a cerebellum dependent function that can be measured with a visuomotor rotation task (VRT). The project aims to identify a sensitive and specific biomarker of cerebellum dysfunction in chronic cannabis users. The investigators would like to demonstrate that the visuomotor rotation paradigm is valid to measure and quantify such a dysfunction. A longitudinal prospective study with a 3 month follow-up is proposed. 3 groups will be included: 1) chronic cannabis users; 2) individuals with an alcohol use disorder; and 3) healthy controls. All groups will be matched by sex and age. Forty individuals will be included in each group. Individuals will be assessed at baseline, at first month and at 3-months of follow-up. Sociodemographic and clinical data will be recorded. Information on cannabis consumption will be registered using an App. Participants will do the visuomotor rotation task and answer three questionnaires: the Intrinsic Motivation Inventory, the Scale for the assessment and rating of ataxia (SARA) and the Harris tests for lateral dominance. The biomarker developed by this project will facilitate the detection of cerebellar alterations in chronic cannabis users, and will permit to quantify and monitor such alteration over time. The team's intention is to patent the proposed model and disseminate it in order to use it in clinical practice at both primary and specialized health centres.
This proposed R21, Effect of CBT Microinterventions on Mechanisms of Behavior Change among Adults with AUD: Using Eye Tracking to Measure Pre-Post Cognitive Control, uses a translational team science approach to isolate and examine the effect of three different Cognitive Behavioral Therapy (CBT) interventions (functional analysis (FA), cognitive restructuring for alcohol related thoughts (CR), and dealing with cravings (DC)) on specific hypothesized mechanisms (cognitive control, stimulus salience, or craving/arousal, respectively).
This study evaluates a brief motivation-building intervention for parents and teens to reduce truancy and substance use. It is hypothesized that the motivational intervention will result in better outcomes compared to an education-only intervention.
Among patients with HIV, especially those also infected with HCV, heavy drinking is associated with significant risks to health. However, little is known about how to best intervene with co-infected heavy drinkers, a particularly high risk group for whom targeted intervention has not been developed. Therefore, this study proposes to test a newly developed drinking-reduction intervention for patients with both HIV and HCV, which combines components of successful interventions developed for HIV and for liver disease patients. 60 HIV/HCV co-infected drinkers from HIV primary care will be recruited in order to ensure an adequate final sample size of 45 participants completing the study. A clinic recruiter will identify and refer potential participants based on their medical record, who will then be screened for eligibility by the research coordinator. Potential participants from outside of this clinic will also be recruited through self-referrals via flyers and through RecruitMe, an online based recruitment tool. Participants will be randomly assigned to an intervention or control condition, while ensuring that equal numbers of individuals with alcohol use disorder are assigned to each condition. The intervention condition will receive brief in-person sessions with a counselor and will be asked to use a smartphone app daily to keep track of drinking and other health behaviors for two months. The intervention sessions will include information about HIV, HCV and alcohol, and the counselor will give the participant information about their liver function and alcohol use to try to motivate them to drink less. The control condition will simply be asked to drink less and will be given pamphlets with general information on HIV, Hepatitis C, and drinking from educational websites on HIV/HCV co-infection. The intervention condition will then be evaluated to see if it was more effective at reducing drinking than the control condition.
Validation of a Test System to develop new medications for alcoholism (TEMA) The 'TEMA', a progressive-work alcohol self-administration paradigm, can be validated by reproducing the effect of Acamprosate and prove the effect of Calcium to reduce motivation to work for alcohol after 14 - 19 days of treatment during a period of 15 - 20 days of alcohol abstinence in a randomized, double-blind, placebo-controlled three-arm parallel-group design.
Research by the investigators' team and others demonstrates that posttraumatic stress disorder (PTSD), depression, alcohol use disorders (AUD), traumatic brain injury (TBI), and chronic pain frequently co-occur among post-9/11 war Veterans and are associated with functional impairment and suicide risk; however, no treatment currently exists that has been specifically designed to promote functional recovery among Veterans experiencing any combination of these most common mental and physical wounds of war. The investigative team has: (A) identified multiple modifiable psychosocial factors (emotion regulation, psychological flexibility, self-compassion) that prospectively predict impairment and suicidal ideation in Veterans; (B) characterized long-term trajectories of resilience and functional disability in Veterans; (C) determined that high utilization of VA mental health services appears to have little, if any, impact on the functional recovery of Veterans on the moderate and severely impaired trajectories; (D) identified psychological flexibility (i.e., the ability to remain present in the moment despite emotional distress and to persist in changing behavior in the pursuit of one's values and goals) as a unique, prospective predictor of membership in the severely impaired functional trajectory and of suicidal ideation, even after accounting for the effects of co-morbidity; and (E) demonstrated that Acceptance and Commitment Therapy (ACT)-a trans-diagnostic, mindfulness-based behavior therapy that seeks to improve functioning by targeting psychological flexibility -can lead to recovery, including sustained improvements in functional disability, quality of life (QoL), suicidal ideation, PTSD, and AUD symptoms among severely impaired Veterans with co-occurring PTSD-AUD. This study is Phase 3 of Project SERVE (Study Evaluating Returning Veterans' Experiences). Through two prior RR&D MERIT awards, SERVE has followed a cohort of post-9/11 Veterans since 2010 and has identified numerous risk and protective factors. SERVE's overall objective is to understand and improve the long-term functional outcomes of post-9/11 Veterans. Consistent with the investigators' conceptual model, the central hypothesis is that psychological flexibility and other trans-diagnostic treatment targets mediate the effects of the most common mental and physical wounds of war on long-term functioning and self-directed violence (i.e., suicide risk). Thus, integrated interventions specifically designed to improve functioning associated with these conditions are most likely to promote long-term recovery among the most impaired Veterans. The investigators will test the central hypothesis and accomplish the overall objective by pursuing the following specific aims: Aim 1: Identify treatment targets that prospectively predict functional disability, family functioning and self-directed violence (SDV) in post-9/11 Veterans with PTSD, depression, chronic pain, TBI, and/or AUD. To achieve this aim, the investigators will follow 500 Veterans for 2 years in order to prospectively evaluate the impact of several novel, treatment-relevant factors on functional disability and SDV over time. H1: Novel factors (mindfulness, perceived burdensomeness, thwarted belongingness, and moral injury) along with established treatment targets (psychological flexibility, self-compassion, and emotion regulation) will prospectively predict functional disability and SDV after accounting for covariates.
Individuals with alcohol use disorder (AUD) will complete one functional Magnetic Resonance Imaging (fMRI) scanning visit. Prior to the scan, individuals will receive a nasal spray of either 24 international units (IU) of oxytocin (OT), or placebo (PBO). During the scan, they will perform the Montreal Imaging Stress Task (MIST), a social stress task. Subjective craving and anxiety data will be collected.
This study is a double-blind, placebo-controlled randomized clinical trial of IBUD (50mg BID) for the treatment of Alcohol Use Disorder (AUD). Eligible participants will undergo a 12-week medication treatment period and 5 in-person visits over 16 weeks.
The specific aims of the ABCT_Military project are as follows: 1) To modify the existing, Alcohol Behavioral Couple Therapy (ABCT) model to treat service members in the reconstitution (post deployment, reintegration, or separation) stage of service, and develop optional psychoeducation modules to address relevant co-morbid problems and challenges in this population in a weekly, 15 session, stand-alone outpatient format. 2) To test feasibility and preliminary efficacy of the study intervention protocol in a successive cohort design for one cohort of 8 couples and one cohort of 22 couples, with iterative manual revision.
This study will evaluate the behavioral effects of alcohol during maintenance on placebo, duloxetine, methylphenidate and duloxetine combined with methylphenidate using sophisticated human laboratory methods.
