Mobile phone apps are a promising data collection and intervention delivery tool for research with substance-using youth, as most teens (73\%) and young adults (92\%) own a smartphone; yet, existing mobile apps in the substance use field lack data collection capabilities and require a therapist to push intervention content. Our team has developed a prototype Android mobile phone app called SARA (Substance Abuse Research Assistant), which features a customizable suite of data collection methods (e.g., sensors, ecological momentary assessments, cognitive/behavioural tasks) and allows for add-on intervention delivery components (e.g., text messages, intervention videos). To mitigate the challenges of long-term app use, SARA creates a game-like environment in which participants can earn non-financial rewards for completing assessments, such as unlocking fish to populate a virtual aquarium on the app{\textquoteright}s home screen. In May-August 2017, SARA will be field tested with 60 participants recruited from the University of Michigan Health System Emergency Department. Screened participants will be eligible if they are 14{\textendash}24 years old, report past-month binge drinking (4/5 drinks tailored by gender) or recreational cannabis use, can download SARA, and provide written consent/assent. Enrolled participants will complete a baseline survey, use the app for 30 days to complete daily and weekly assessments, and provide feedback about the app at follow-up. Key findings will include: assessment compliance rates; participants{\textquoteright} interaction with SARA during field testing; and participants{\textquoteright} feedback about SARA, including their comfort answering sensitive questions via the app. Our findings will indicate the feasibility and acceptability of using SARA as a data collection and intervention delivery tool with substance-using youth in behavioural research.}, issn = {1353-8047}, URL = {https://injuryprevention.bmj.com/content/23/Suppl_1/A37.1}, eprint = {https://injuryprevention.bmj.com/content/23/Suppl_1/A37.1.full.pdf}, journal = {Injury Prevention} }
