Summary

The proposed study will provide critical information on Ecological Momentary Assessment (EMA) design characteristics that promote retention in a vulnerable and under-represented population in research-youth experiencing homelessness. The study will use an EMA app to collect substance use, mood, craving, social surroundings, and trauma measures over a 14-day period in youth age 18-24 (n=40) recruited from Star House, a homeless youth drop-in center. Youth will be randomized in 2x2 factorial design (fixed incentive model vs. prize-based model; random assessment 3x vs. 6x per day).

Conditions

• Substance Use

Interventions

Type	Name	Description
BEHAVIORAL	Ecological Momentary Assessment (EMA; Metricwire) Prompts 3x/day	Participants receive 3 EMA survey prompts daily for the duration of the study.
BEHAVIORAL	Ecological Momentary Assessment (EMA; Metricwire) Prompts 6x/day	Participants receive 6 EMA survey prompts daily for the duration of the study.
BEHAVIORAL	Incentive Structure - fixed	Those assigned to the "fixed" incentive condition will earn a fixed bonus based on EMA completion (50-74%=$3; 75-89%=$5; ≥90%=$10) each week.
BEHAVIORAL	Incentive Structure - prize based	Those assigned to the "prize-based" incentive will be rewarded for high survey completion with increasing numbers of "draws" depending on their level of response to EMA prompts each week (50-74%=1 draw, 75-89%=2 draws, ≥90%=3 draws). For each draw, individuals will use the EMA app to "spin the wheel" to see which prize amount they earn. Out of a total of 500 total draws, 50% will be $1, 43.6% will be $3, 6% will be medium prizes ($5), and 0.4% will be a "jumbo" prize ($90).
