Supporting Adolescents to Adhere - an Intervention Using Airtime Rewards Allocated by a Prize Drawing (SATA)

15. februar 2018 oppdatert av: RAND

This study is an extension of Reminding Adolescents to Adhere (RATA) (Unique protocol ID: 1R01HD074925-01). Participants for SATA will be recruited during the RATA month 24 exit survey.

Participants will be randomized 1:1:1 into either one of two intervention group (receiving the weekly messages and a chance to draw a prize at each clinic visit based on either a fixed adherence level of 90% or a self-chosen one of at least 80% as further detailed below) or the control group that receives the existing RATA intervention consisting of weekly motivational messages and the chance to get mobile airtime rewards conditional on responding. Doing so will allow the investigators to cleanly evaluate the impact of these additional adherence-based lotteries, and guarantees that those who have been in the control group receiving standard of care in the first 24 months of the RATA intervention will also receive an intervention for reasons of fairness.

Detaljert beskrivelse

  • For Group 1 (lottery reward with fixed target): Study coordinators check participant's MEMS extraction for last month's adherence. Study coordinators then tell participants of the participants' adherence in the last month. Participants are also informed that during the next clinic visit, if they adhere at least 90 percent they have a chance to enter into a game where they have a chance of winning mobile airtime, by drawing into a bag and picking a card associated with their airtime winnings. If they do not have 90% adherence, they will not receive the airtime award game, but there will be another chance the next time they come for their scheduled clinic visit during the study period.
  • For Group 2 (lottery award with own target): Study coordinators check participant's MEMS extraction for last month's adherence. They inform participants of their adherence in the last month. In order to be eligible for an airtime reward game, during their next clinic visit they must reach their own target goal. The target adherence goal must be greater than 80%. Participants may, for example, choose 80%, 85%, 90%, 95%, or 100%. Again, if they meet or exceed this target they have a chance to draw into a bag to win mobile airtime. If they do not have meet this self-imposed target adherence, they will not be eligible to play the airtime award game, but there will be another chance the next time they come for their scheduled clinic visit during the study period.

During each clinic visit, participants will have their MEMS extracted and study coordinators will check for average adherence between that day and the last clinic visit. For those who have met the target, coordinators will initiate the lottery, complete the drawing procedure, or send them the airtime reward without drawing (depending on which group).

Every Sunday, study investigators will send treatment participants a motivational message to remind them about the reward. Within each of the two intervention groups, study investigators will randomly send the message either in a loss-frame or a gain-frame, i.e. an intervention participant (in either group) will some weeks receive a message telling them to keep up motivation (as a code-word for adherence) to win a prize, and some weeks telling them to make sure not to lose their chance to win a prize.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: Own Adherence Group
Participant chooses their adherence level to be reached at next clinic visit (at least 80%, but can be higher). If they reach that percentage measured using the MEMS cap, they can participate in a lottery for an airtime reward of none, a small amount, and a larger amount. Participants also receive a weekly motivational message reminding them of their incentive to adhere. If they respond to the message they will receive airtime top-up.

Eksperimentell: Fixed Adherence Group
Participant is told to meet a pre-determined target of 90%. If they reach that percentage measured using the MEMS cap, they can participate in a lottery for an airtime reward of none, a small amount, and a larger amount. Participants also receive a weekly motivational message reminding them of their incentive to adhere. If they respond to the message they will receive airtime top-up.

Aktiv komparator: Control Group
Participants do not receive a lottery incentive conditional on adherence. Participants will however, continue to receive weekly messaging with airtime top-up contingent on response.

Tidsramme
Medication adherence rates using electronically monitored adherence (MEMS cap) data
Tidsramme: 9 months after enrollment
Medication Event Monitoring System (MEMS)-cap data will be collected continuously over the course of the 9-month study period allowing the study investigators to investigate daily adherence and its timing. MEMS caps data indicating the date and time when the participant opened their pill bottle (either one of the ART medications or prophylaxis if not on ART yet) will be used to calculate the primary outcome variable of adherence (# of actual bottle openings / # of prescribed bottle openings).
