Filter by:There is a need to better understand the mechanisms underlying alcohol use and dependence in order to advance the clinical treatment of alcohol dependence. Here, the investigators will use Positron Emission Tomography to determine if there is an up-regulation of D3 receptors in the brains of subjects with alcohol use disorders. The investigators will also investigate the relationship between D3 binding and major phenotypes associated with alcohol use disorders, namely: alcohol cue induced craving and motivation to self-administer alcohol in the laboratory.
This study is a double-blind, randomized, placebo-controlled, parallel group, two-site study designed to assess the effects of varenicline as compared with placebo on responses to in vivo alcohol cue exposure in the human laboratory setting.
Impulsivity is a central feature of addiction. Nalmefen is an authorized treatment for alcohol addiction. Baclofen has empathically been advocated to have some efficacy in this indication. The aim of the present study is to test the effect of Nalmefene and Baclofen on impulsivity. Primary study objective: To examine the effect of Nalmefene and Baclofen on impulsivity (as measured by the Stop Signal Task) in subjects with alcohol use disorder and healthy control subjects. Main secondary study objectives: To examine the effect of Nalmefene and Baclofen on risk taking (as measured by the Balloon Analogue Risk Task) and on the preference for small immediate rewards over large delayed rewards (as measured by the Delay Discounting Task). To compare subjects with alcohol use disorder and healthy control subjects on these tasks. Primary study outcome: Stop-signal reaction time in the Stop-Signal Task Main secondary study outcomes: Equivalence point in the Delay-Discounting Task and Average number of pumps delivered in the Balloon Analogue Risk Task Study Design: Randomized, placebo control, cross-over, single-dose
New technologies offer potential ways to provide and deliver preventative interventions. With respect to unhealthy alcohol use, offering people tools to assess and manage their risk at any given time using their smartphone may represent an additional opportunity to disseminate preventative interventions. Nevertheless, there is a lack of knowledge on the acceptability and efficacy of smartphone applications for unhealthy alcohol use. Alcooquizz, a smartphone app, has been previously evaluated using a before/after design without randomization, with participants reporting reductions in drinking over time. The current trial proposes to conduct an RCT, comparing reductions in alcohol consumption between participants provided access to Alcooquizz to a no intervention control. Participants will be recruited through Amazon's MTurk crowdsourcing platform. Potential participants identified as problem drinkers based on an initial survey will be invited to complete another survey in 6 months time. Those who agree to be followed-up will be randomized to be provided a link to download the Alcooquizz app or to a no link control condition. At six-months post-baseline, the MTurk portal will be used to send invitation emails that contain a link to the follow-up survey that asks about their drinking and their impressions of the app. The primary hypothesis to be tested is that participants receiving access to the Alcooquizz app will report a greater level of reduction in number of drinks in a typical week between the baseline survey and six-month follow-up as compared to participants in the no information control condition.
Alcohol misuse and smoking constitute two of the three leading preventable causes of death in the United States. The purpose of this research study is to develop an intervention designed to help people stop drinking alcohol and stop smoking at the same time.
The proposed research will investigate whether smokers with vs. without current at-risk alcohol drinking (ARD) respond to reduced nicotine cigarettes by increasing their alcohol consumption or smoke exposure, thereby diminishing the hypothesized public health benefit of these new products.
The objective of the proposed project is to conduct a randomized controlled trial (RCT) comparing sexual assault perpetration and related outcomes (i.e., bystander behavior; rape myth acceptance) for men who receive a group alcohol intervention only to men who receive a group integrated alcohol and sexual assault intervention.
This laboratory study will employ a repeated measures experimental design to examine the effect of high (7.2% THC) and moderate (3% THC) dose of marijuana, relative to placebo, on alcohol craving and on behavioral economic measure of alcohol demand after exposure to alcohol cues, and on subsequent drinking in an alcohol choice task in which participants choose either to drink or receive monetary reinforcement for drinks not consume. The study will recruit 173 non-treatment seeking heavy episodic alcohol drinkers who smoke marijuana at least twice weekly.
Alcohol is one of the leading contributors to premature mortality and disability. Most people with alcohol problems will never seek treatment. There is a need to develop alternate ways to help problem drinkers outside of formal treatment settings. One promising strategy is Internet-based interventions for problem drinkers. Our recently completed RCT comparing a brief (Check Your Drinking; CYD) versus an extended (Alcohol Help Centre; AHC) Internet intervention for problem drinkers found that, while there was a reduction in drinking across time for both interventions, there was no significant (p > .05) difference in reductions in drinking between the two interventions. Based on these results, it is not justifiable to say that either intervention 'worked' as there was no comparison condition of participants who received no active intervention. The current trial proposes to address this limitation by conducting an RCT comparing the CYD, AHC, and a no intervention control condition. Participants will be recruited through Amazon's MTurk crowdsourcing platform. Participants identified as problem drinkers based on an initial survey will be invited to complete another survey in 6 months time. Those who are interested will be randomized to receive access to the Check Your Drinking screener (CYD condition), Alcohol Help Centre (AHC condition) or a feedback questionnaire (control condition). At six-months post-baseline, the MTurk portal will be used to send invitation emails that contain a link to the follow-up survey. The primary hypothesis to be tested is that participants receiving access to the AHC intervention will report a greater reduction in AUDIT-C scores and in number of drinks in a typical week than participants in the CYD intervention. Further, participants in the CYD condition will report a greater level of reduction AUDIT-C scores and in number of drinks in a typical week between the baseline survey and six-month follow-up as compared to participants in the no intervention control condition.
The study aims to investigate the effects of a short computerized training as a therapeutic add-on to standard therapy in patients with alcohol-use disorder.
