Filter by:The project proposes to continue the development of an intervention for relapse prevention in the form of a professional quality video game which rewards drug-rejecting physical motions and spoken refusal phrases. Phase I research findings showed that youth in recovery experienced increased low craving levels, strong levels of satisfaction, and interest in attending treatment sessions where the intervention is available - an important outcome since failure to attend treatment is highly correlated with relapse. In Phase II, the investigators propose to modify and expand the prototype based on customer feedback from treatment centers, counselors and patients. The investigators will test the effectiveness of the motion and voice-controlled game in a randomized controlled trial of youths in treatment for opioid use disorder who have access to the game for a month. The investigators will measure the effect of gameplay on successful completion of detoxification/inpatient treatment and rates of linkage to next level of outpatient treatment. The investigators will also measure the effect of gameplay compared to treatment as usual (TAU) during a subsequent episode of outpatient treatment (following inpatient), on rates of treatment attendance, treatment retention, urine drug test results, substance use self-report, treatment alliance, drug craving, and treatment satisfaction.
This study will examine the effects of doses of marijuana/placebo and doses of opioid/placebo, alone and in combination. The primary outcomes are related to pharmacodynamic measures (subjective ratings of drug liking and other abuse-related effects; physiological outcomes) to determine the interaction effects of these compounds.
This study will examine the effects of various strains of marijuana on simulated driving performance; the effects of alcohol administration will also be examined to further understand how marijuana-induced driving changes compare to the effects of alcohol. Secondary outcomes will include physiological effects, subjective- and observer-rated outcomes, and psychomotor performance under the various dose conditions.
