简要总结
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).

研究组 & 干预措施
EMA, 3x/day, fixed incentive
Ecological Momentary Assessment (EMA; Metricwire). Participants randomized to this group will be sent prompts through the EMA app to complete brief EMA survey at 3 random times per day. Participants randomized to this group will earn a fixed bonus/incentive based on completion of the EMA surveys (50-74%=$3; 75-89%=$5; ≥90%=$10) each week.

EMA, 6x/day, fixed incentive
Ecological Momentary Assessment (EMA; Metricwire). Participants randomized to this group will be sent prompts through the EMA app to complete brief EMA survey at 6 random times per day. Participants randomized to this group will earn a fixed bonus/incentive based on completion of the EMA surveys (50-74%=$3; 75-89%=$5; ≥90%=$10) each week.

EMA, 3x/day, prize-based incentive
Ecological Momentary Assessment (EMA; Metricwire). Participants randomized to this group will be sent prompts through the EMA app to complete brief EMA survey at 3 random times per day. Participants randomized to this group will be rewarded for high survey completion with increasing numbers of "draws" for prizes depending on their level of response each week (50-74%=1 draw, 75-89%=2 draws, ≥90%=3 draws).

主要结局
Length of Time
时间窗: Baseline to end of trial (day 14)
Total length of time in days using EMA (range: 1-14 days). Higher values represent greater length of time EMA was used.
Percent Completion
时间窗: Baseline to end of trial (day 14)
Percent of EMA surveys completed (0-100%). Higher values represent a larger percentage of EMA surveys completed.
