Measure
Provision of Multiple Self-tests
Participants in intervention clusters will be given multiple HIV self-test kits, testing instructions, and advice to use their discretion when offering self-tests to selected sexual partners. Participants will be encouraged to offer self-tests primarily to current and potential partners with whom unprotected sex is likely. All participants will be encouraged to use condoms with sexual partners. Participants will also be advised to assess the risk of intimate partner violence (IPV) as a result of offering self-tests to partners. Participants will have opportunities to obtain additional HIV self-test kits on a monthly basis. Provision of multiple self-tests: Participants will be given multiple Oraquick Advance HIV-1/2 test kits for testing themselves more frequently and for offering to selected sexual partners. The self-test kits will be given to participants on a monthly basis as needed. The intervention is designed to facilitate partner and couples testing, with resulting reduction in risky sexual behavior and HIV incidence among participants.
Referral Vouchers for VCT
Participants will be given a multiple referral vouchers for HIV testing to distribute to their sexual partners. All participants will be encouraged to use condoms with sexual partners. These referral vouchers will encourage the partners to seek HIV counseling \& testing services in local clinics. Participants will also be advised to assess the risk of intimate partner violence (IPV) as a result of offering referral vouchers to partners. Participants will have opportunities to obtain additional referral vouchers on a monthly basis.

HIV Incidence Per 100 Person Years
1.18 cases per 100 person years
.98 cases per 100 person years

SECONDARY outcome

Timeframe: up to 24 months

Average number of sexual partners per participant that the participant reported as HIV positive over the course of the study (Total reported positive sexual partners divided by number of participants who completed at least one 6-month follow-up survey); the intent of this measure is to see if participants given HIV self-tests are more likely to identify HIV positive sexual partners.

SECONDARY outcome

Timeframe: Data was measured longitudinally up to 24 months for some subjects; all participants were measured through 18 months. Measures reported are from 18 month follow-up for behavior occurring in the past 6 months.

Population: Secondary outcomes were assessed at 6, 12, 18, and 24 month surveys. HIV testing (primary outcome) also occurred at 9, 15, and 21 months, so the number of overall participants may not match what is reported for the primary outcome.

Percentage of participants who used a condom with at least one sexual partner after partner refused self-test or HIV testing services referral card, or tested HIV-positive; Note that percentages are rounded to one decimal place.
