EMA of Substance Use in Homeless Youth

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).

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • currently homeless, defined as lacking a fixed, regular, and adequate nighttime residence.
  • report any of the following past-month frequencies of substance use (NIDA ASSIST screen) used in prior EMA studies: a) heavy episodic or "binge" drinking (≥4 drinks per day for women/≥5 drinks for men) ≥2 days per month ; b) marijuana use ≥2 days per week; or c) any illicit drug use.

Treatment and study plan

Ecological Momentary Assessment (EMA; Metricwire) Prompts 3x/day

Behavioral

Participants receive 3 EMA survey prompts daily for the duration of the study.

Ecological Momentary Assessment (EMA; Metricwire) Prompts 6x/day

Behavioral

Participants receive 6 EMA survey prompts daily for the duration of the study.

Incentive Structure - fixed

Behavioral

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.

Incentive Structure - prize based

Behavioral

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).

Primary outcomes

  1. Length of Time

    Time frame: 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.

  2. Percent Completion

    Time frame: Baseline to end of trial (day 14)

    Percent of EMA surveys completed (0-100%). Higher values represent a larger percentage of EMA surveys completed.
