Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Medication adherence rates using electronically monitored adherence (MEMS cap) data

    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).

    9 months after enrollment

Secondary Outcomes (3)

  • Fraction of clients displaying adherence of 90% or more

    9 months after enrollment

  • Indicator for treatment interruptions of more than 48 hours

    9 months after enrollment

  • Viral load assays

Study Arms (3)

Own Adherence Group

EXPERIMENTAL

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.

Behavioral: Own Adherence Group

Fixed Adherence Group

EXPERIMENTAL

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.

Behavioral: Fixed Adherence Group

Control Group

ACTIVE COMPARATOR

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.

Behavioral: Control Group

Interventions

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.
