Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The specific aims of the study are
Specific Aim 1: Continued Feasibility Evaluation. In our preliminary work, we demonstrated that 1) youth perceive MOMENT to be easy to understand, comfortable, motivating, and helpful in reducing their marijuana use, 2) we can recruit 4 participants/month (minimum rate for the proposed study), and 3) we can successfully implement a MOMENT intervention study in the proposed recruitment sites. Based on this work, we have identified additional areas of feasibility on which to focus in the proposed study. Specifically, we aim to achieve:
1a. A signal response rate of at least 70% during each of three periods of momentary data collection - baseline, intervention, and 3-month follow-up.
1b. A diary response rate of at least 70% during each momentary data collection period
1. c. A retention rate of at least 80% of participants at the 3-month follow-up.
Specific Aim 2. Early-Stage Efficacy Exploration. Our preliminary work showed that both momentary and individual-level outcomes improved from baseline to three months post-intervention. The primary momentary outcomes are desire to use marijuana when in a triggering context and likelihood of use following exposure to a triggering context. The primary individual-level outcomes are number of use events/week, 30-day percent of days abstinent, dose/use event, and measures of motivation (importance of, readiness for, and confidence about reducing use). Based on the preliminary findings, we will explore these early-stage efficacy questions:
2. a. Will improvements in momentary outcomes be observed with MOMENT, but not MET-only?
(1) The association between exposure to self-identified trigger contexts and momentary desire to use marijuana will be attenuated at three months, compared to pre-intervention.
(2) The likelihood of marijuana use following exposure to a trigger context will be reduced at three months.
2b. Will improvements in individual-level outcomes be greater with MOMENT vs. MET-only?
1. The reduction in marijuana use frequency (events/week and 30-day percent of days abstinent) and dose (per use event) will be greater at three months.
2. The increase in motivation to reduce or discontinue use will be greater at three months.
