Retention and incentives for participation
Based on our pilot work and previous clinical trials in which we have obtained follow up completion rates of 85–90% (e.g., R01AT006948; K23HL107391; R44DA022167) Participants will receive $50 at each primary assessment completed [Baseline 1, Baseline 2, End-of-Treatment (12 weeks), and 6-, 9-, and 12-month follow-ups]. Transportation costs (taxi service, bus fare, mileage, and/or parking vouchers) to an in-person assessment will be paid for by the study. Participants will be paid $5 each for completion of counseling sessions 3, 4, 5, and 6 and a $20 bonus if that participant completes all four of these sessions. Remuneration for counseling sessions 3–6 was added (see Table We will provide participants with study marketing materials (e.g., coffee mugs, water bottles, tote bags) that will include the study name, logo, phone number, and email. We will offer one item at Baseline 2 (1 week post-discharge) and one item at any follow-up assessment visit (12w, 6 m, 9 m, 12 m) attended in person. New Years and mid-Summer cards with the study logo will be sent to all study participants through the duration of their participation. Incentives and provision of marketing materials will be identical in each condition. We will send text, email, and/or mail reminders in advance of each assessment. We will obtain three “emergency contacts” (i.e., who will know how to reach the participant should their phone number be out of service) from each participant and these contacts will be updated as needed throughout the study.Participants who do not have regular access to a phone or those who lose access to a phone during the first year of enrollment will be offered a study issued cellphone to complete study activities. Upon completion of the 12-month outcomes assessment, participants using study issued cellphones will be compensated $20 for returning the phone to study staff.
