Patient participant compensation
Patient participants receive compensation in the form of debit cards or gift cards for completing study activities including surveys, urine drug screening, and updating contact information (total possible $670 for full participation). Intervention patients also get $3 per telephone health coaching to offset the cost of data usage on mobile phones (maximum $18) but are not otherwise compensated for participation in any aspect of the intervention. A subsample of intervention patients who undergo qualitative interviews to assess the intervention experience receive a further $50.
