Actual (reported)The randomized clinical trial involves the pilot-testing of a theory-guided, empirically based, and low-cost intervention designed for legal medical marijuana-using parents to enhance parenting behaviors that limit youth exposure to marijuana, reduce or halt youth marijuana use, and increase youth awareness of the harmful consequences of marijuana during the youth years. Parents will be randomized to an intervention condition or to a wait list control condition. Pre- and post-intervention assessments will evaluate parent and youth marijuana and other substance use, perceptions and attitudes about marijuana, parenting and family functioning, and youth behavioral health.

The TLFB will be used to derive a measure of percent days of marijuana and other drug use in the past 12 weeks at three time points (baseline, 3-months follow-up, and 6-months follow-up) and analyzed to quantify change from baseline to 3-months and change from 3-months to 6-months.

Perceptions of Harmfulness of Marijuana Use Adolescent Report (PMHU-A)
The PMHU-A measure is based on items from the National Survey of Drug Use and Health (NSDUH). Five items from the NSDUH will be used to measure the respondent's perception about the harm of using marijuana pertaining to physical harm, harm to mental health, risk for marijuana dependence, risk for injuries, and harmful social consequences. Each item has the same response option (1=no risk, 2=some risk, 3=moderate risk, 4=high risk). Items will be summed to form a total score at each assessment point (range, 5-20), with the greater the scale score the more perceived risk. The PMHU will be used to derive a measure of perception of harm at three time points (baseline, 3-months follow-up, and 6-months follow-up) and analyzed to quantify change from baseline to 3-months and change from 3-months to 6-months.

CAP is a parent-focused intervention being developed to help parents in states with legalized medical marijuana to address adolescent marijuana use. The proposed intervention will address the effects of marijuana on adolescent behavioral health, brain development, and social functioning and enhance parent motivation to use CAP concepts. Guided by formative research, CAP will build skills and provide strategies to: (1) restrict adolescent exposure to cannabis products and parent cannabis use in the home, (2) improve parent communication about their own cannabis use and expectations about youth marijuana use, (3) improve monitoring, (4) increase positive reinforcement for youth abstinence, and (5) address parent negative emotions. Parents will meet in groups with an interventionist for two 75-minute sessions. Presentations, discussion, and roleplay will be used to help parents gain mastery of preventive parenting behaviors and related strategies to reduce adolescent marijuana use.
Parents randomly assigned to Wait List Delayed CAP (WL) will receive no intervention for the baseline to 3-month follow-up period. Thus, the WL condition will serve as a comparison group from baseline to the 3-month assessment point. After the 3-month follow-up assessment, WL parents will be offered the CAP intervention. The final assessment for the WL participants will function as a 3-month follow-up assessment, allowing us to aggregate data all 60 parent-adolescent dyads to conduct within group analyses of pre- to post-intervention change on key variables of interest.
The Cannabis Actions and Practices (CAP) resource is a parent-focused approach to help MM parents address marijuana use and attitudes by their adolescents. CAP includes information about the effects of marijuana on adolescent behavioral health, brain development, and social functioning. CAP also integrates motivational strategies to foster The CAP intervention focuses on building parenting skills and teaching strategies to: (1) limit adolescent exposure to cannabis products and parent cannabis use at home, (2) improve parent communication about their MM use, expectations about youth marijuana use, and attitudes about the potential harms of adolescent cannabis use, (3) improve monitoring, and (4) increase positive reinforcement for youth abstinence. Parents meet with an interventionist for two individual 75-minute sessions involving presentations, discussions, and behavioral rehearsal of key parenting skills.
