Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to evaluate the efficacy of engagement strategies for increasing daily data collection adherence among substance-using youth between the ages of 14 and 24. The primary hypotheses of this study are that: (1) receiving a reinforcer after completing daily data collection activities will predict next-day completion of targeted data collection activities; and (2) receiving a notification prior to 6pm (when data collection activities open) will predict same-day completion of data collection activities.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Substance use among adolescents and emerging adults remains an alarming public health issue which is associated with the leading causes of death. Although mobile applications are a promising data collection tool for understanding substance use among youth, existing mobile applications are limited in that they are not readily modifiable nor designed for long-term use. To address these challenges, our research team has developed a prototype mobile application named SARA (Substance Abuse Research Assistant) that contains multiple data collection tools (e.g., ecological momentary assessments, active tasks) and features various engagement strategies (reinforcers or notifications) designed to encourage data collection adherence over an extended period of time.

Baseline reinforcers which are administered to all participants include: (1) a virtual aquarium that participants see after opening the app; (2) virtual fish to populate the aquarium, which participants can earn points to unlock by completing daily data collection activities; (3) a new aquarium interface (i.e., leveling up) that participants unlock after using the app for a predetermined amount of time; (4) small financial rewards for each 3-day streak of completing daily data collection activities; and (5) reminder text messages/phone calls from research staff following predetermined reminder schedules. Key reinforcers and notifications are described in detail in the "intervention" section.

This study examines the impact of these key engagement strategies on participant compliance with daily data collection activities over a 30 day field testing period. The primary analyses will use a log linear generalization. The primary longitudinal binary outcome for the reinforcers will be whether on the following day the participant completes one or more self-report validated survey items. The secondary longitudinal binary outcome for the reinforcers will be whether on the following day the participant completes both active tasks. Survey questions answered prior to the randomization as well as the completion of one or more survey questions on the day prior to randomization, and the completion of both active tasks on the day prior to randomization, may be used as control variables in the above analyses of reinforcers. The primary longitudinal binary outcome for the notifications will be whether on the same day the participant completes one or more self-report survey questions. The secondary longitudinal binary outcome for the notifications will be whether on the same day the participant completes both active tasks. The completion of one or more survey questions on the day prior to, and the completion of both active tasks on the day prior to, the randomization will be included as control variables for the notifications.

Allocation Method

NA

Intervention Model

SINGLE_GROUP

At each time point at which a participant is eligible to receive an engagement strategy, the participant is randomized to either receive the strategy or not receive the strategy. Participants are only eligible to potentially receive some engagement strategies after completing their self-report survey questions and/or active tasks that day (see "intervention" section for more information).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Within-participant micro-randomization

Intervention includes Reinforcers and Notifications through the app. At each available decision time, each participant is randomly assigned to either receive an engagement strategy or to not receive an engagement strategy.

Group Type EXPERIMENTAL

Reinforcers

Intervention Type BEHAVIORAL

Memes/Gifs: Immediately after completing their daily ecological momentary assessment using the app, each participant is randomized to receive an inspirational or funny meme or gif that is displayed within the app. Life Insights: Immediately after completing both daily active tasks using the app, each participant is randomized to unlock a life insight. Life insights track data provided by the participant, are stored in a virtual library within the app, and are regularly updated with recent data points.

Notifications

Intervention Type BEHAVIORAL

Reminder Push Notifications: All participants receive a push notification reminder from the app at 6pm (the time at which data collection opens) to complete their daily data collection activities. Each day, each participant will be randomized to receive either a generic reminder or a reminder that contains more detailed information (e.g., about upcoming incentives). Inspirational Push Notifications: Each day, each participant will be randomized to receive a push notification at 4pm that contains inspirational song lyrics or celebrity quotes.
