Brief Summary:
The purpose of this study is to evaluate the efficacy of a Substance-Free Activity Session (SFAS) as a supplement to a brief motivation intervention (BMI) in reducing marijuana use and drug-related consequences in college student

Condition or disease Intervention/treatment Phase
Marijuana Use Behavioral: Brief Motivational Intervention (BMI) Behavioral: Substance-Free Activity Session (SFAS) Behavioral: Relaxation Session Not Applicable

Detailed Description:
Approximately 20% of college students are regular marijuana users, and are at risk for cognitive and academic problems, addiction, and risk behaviors such as driving while impaired. Young adult marijuana users are thus a high-risk population and may require an intervention that motivates marijuana reductions by increasing engagement in constructive alternatives to marijuana use. Brief Motivational Interventions (BMIS) have demonstrated efficacy for alcohol use in college students, but lack consistent evidence of efficacy for marijuana use. This research team has developed a supplement to alcohol BMIs, the Substance-Free Activity Session (SFAS), which directly targets the behavioral economic mechanisms of both substance-free reinforcement and delayed reward discounting by encouraging the development of and commitment to academic and career goals, and by highlighting the impact of day-to-day patterns of alcohol use and academic engagement on these goals. A controlled pilot trial found that the SFAS improved BMI outcomes in a sample of heavy drinking college students, and the ongoing parent trial to this revision is replicating and extending those results. This study will evaluate the SFAS using a randomized 3-group (BMI + SFAS vs. BMI + Relaxation Attention Control, vs. Assessment Only) pilot trial with 120 undergraduates (50% female, 40% minority) who report using marijuana on > 5 days in the past-month. It is hypothesized that at the 1-month and the next-semester follow-ups (follow-ups are wedded to the academic calendar to allow for representative measurement of marijuana use and activity patterns) BMI+SFAS participants will report significantly lower levels of marijuana use and problems, and that these reductions will exceed those of BMI + Relaxation and Assessment-Only participants. Exploratory analyses will test the hypotheses that (a) the BMI + SFAS will be more effective for participants who report higher baseline marijuana reinforcing efficacy and delayed reward discounting; and (b) the advantage of BMI + SFAS on marijuana use will be mediated by increased participation in substance-free activities. Support for our hypotheses would extend behavioral economic theory and would provide initial validation for an approach that could be used to reduce marijuana misuse among the increasing population of college students who misuse marijuana. Furthermore, given the focus of the SFAS is to increase academic/campus engagement, this work has the potential for widespread dissemination.

Arm Intervention/treatment
Experimental: BMI + SFAS
Participants first receive a 50-minute standard brief motivational intervention designed to reduce marijuana use. A week later, they will receive the SFAS (Substance-free Activity Session., a 50-minute counseling session designed to increase the salience of the student's academic and career goals, draw attention to the potentially negative relationship between substance use and goal accomplishment, and increase engagement in substance-free alternative activities. The SFAS was described to participants as the "College Adjustment Session" and the session was conducted using an MI plus personalized feedback approach.
Behavioral: Brief Motivational Intervention (BMI)
This session includes a discussion related to harm reduction and the student's autonomy to make decisions about the information provided in the session; a marijuana use decisional balance exercise; personalized marijuana-related feedback, and goal-setting. Elements included in the feedback are: (a) comparison of the student's perception of how much college students use marijuana and actual student norms, (b) a comparison of the student's marijuana use vs. norms, (c) drug-related problems experienced, (e) money spent on marijuana, and (f) alcohol norms and consequences if participants indicated they also drink alcohol. Participants discuss the personalized feedback with the clinician and review protective behavioral strategies if she or she indicates interest.

Behavioral: Substance-Free Activity Session (SFAS)
The clinician initiates a discussion of the student's college and career goals. Students discuss the values that motivate them as well as how marijuana use may interfere with their ability to accomplish these goals. Students then receive information on graduation rates and income benefits for those who attend and excel in college. They receive personalized feedback on (a) the requirements for their major and intended career, (b) a list of extracurricular activities tailored to their goals, (c) a graph showing time they allocate to their activities, (d) information on stress and depressive symptoms (if applicable) and possible adaptive coping responses and (e) a list of substance-free recreational activities in which they would like to start or continuing engaging.

Active Comparator: BMI + Relaxation Session
Participants first receive a 50-minute standard brief motivational intervention designed to reduce marijuana use. A week later, they will receive a relaxation training session. In the relaxation training session, the clinician leads the student through a diaphragmatic breathing exercise, followed by a progressive muscle relaxation protocol (~30 minutes). At the end of the session, students were asked about their reaction to the relaxation techniques and were provided with relaxation training handouts.

Behavioral: Relaxation Session
The session includes a clinician-led diaphragmatic breathing exercise, followed by a progressive muscle relaxation protocol (~30 minutes). At the end of the session, students are asked about their reaction to the relaxation techniques and are provided with relaxation training handouts.

No Intervention: Assessment
Participants fill out a battery of measures and receive no intervention.
