Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to test feasibility and acceptability of a lottery to help women in Cape Town, South Africa to continue using long-acting reversible contraceptives to avoid unintended pregnancies, and to also use condoms to reduce sexually transmitted infections including HIV.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The overall objective is to implement a pilot project offering conditional economic incentives (CEI) for dual protection (the prevention of HIV or other sexually transmitted infections and pregnancy via the simultaneous use of condoms plus effective contraception) among young women in Cape Town, South Africa, to test feasibility and acceptability, and to gather preliminary evidence on effect sizes to inform a future efficacy trial. CEI are an innovative structural approach for dual protection, which so far has not been tested in generalized HIV epidemic settings. The project has three aims. First, it will test the feasibility and acceptability of a conditional economic incentive (CEI) program to incentivize dual protection among young women in Cape Town. The working hypothesis is that a program with modest economic incentives in the form of a lottery to continue using modern contraception and stay free of sexually transmitted infections (STI) can be implemented among young women who express a desire to avoid unintended pregnancies. The hypothesis is that the CEI treatment group will exhibit greater program participation and retention rates as compared to the control group. Second, the study will obtain estimates of the effect of CEI on the primary outcomes (adherence to the dual protection regimen) through: (1) continuation of a contraceptive method of choice throughout the six month study period, and (2) self-reported condom use. Contraceptive continuation will be measured via clinic records (proxy for clinical checkup) at the 3 and 6 month follow up visits. Self-reported condom use will not be used to provide any incentives. The hypothesis is that receipt of CEI (lotteries) will be associated with higher rates of dual protection. Third, the study will examine the degree to which CEI (lotteries) impact secondary outcomes: a urine pregnancy test and STI status (measured at baseline and 6 month follow up). A selected STI (syphilis) will be monitored for assessment of the STI outcome, using a rapid test that can be administered at clinic level. The working hypothesis is that the participants in the CEI (lottery) treatment group will have reduced rates of STI and they will have lower rates of pregnancy.

This pilot trial will include young women, ages 18-40, recruited from a community clinic in Cape Town. A maximum of 96 women will be randomly assigned to one of two arms (n=48 each) in a randomized controlled trial design. In the trial, Arm 1 (control) will receive transport compensation for study visits at each of the study visits at baseline and at months 3 and 6. Arm 2 (intervention) will receive transport compensation for study visits at each visit at baseline and at months 3 and 6, plus the opportunity for entry in a lottery. Participants in Arm 2 will have a chance to receive two lottery tickets: (a) the first when returning by month 3, subject to confirmation of continued use of the participant's preferred contraceptive; (b) the second upon completion of the six month study period, subject to confirmation of continued use of the participant's preferred contraceptive over the course of the 6 month study period; and if they are free of a new curable STI. The lottery tickets will enter the participant into a drawing for a prize at month 3 and at the end of the six month study period. All participants will receive transport compensation each time at baseline, month 3 and month 6. There will be 15-20 minute follow-up sessions for everyone at months 3 and 6 when receiving STI results, and CEI (lotteries) for those in the treatment group. At month 3, follow-up sessions will include some reinforcement of key messages related to dual protection. At months 3 and 6, the follow-up sessions will include administration of the study questionnaire.

Study Groups

Lottery

Conditional economic incentive (CEI) lotto arm participants will get a chance to win a type of lottery or "lotto" ticket with a 50% chance of winning each time: (a) if they come back to the clinic and are still using a modern contraception method after 3 months (including IUD, injectable contraceptive, or implant); (b) if they come back to the clinic and are still using modern contraception after 6 months; and (c) if they come back to the clinic at 6 months and they don't have a new curable STD (such as syphilis).

They will also will receive reimbursement to cover their transport and time at baseline, at 3 months and at 6 months.

Group Type EXPERIMENTAL

Lottery

Intervention Type OTHER

Opportunity for entry in lottery (each time, at months 3 and 6).

No Lottery

Participants in the Control (No CEI Lotto) group will receive reimbursement to cover their transport and time at baseline, at 3 months and at 6 months; they will NOT have a chance to win a lottery even if they are still using a modern contraception and are free of new curable STDs.
