Abstract
This study aims to test whether providing information that intends to relieve individuals concerns about HIV-related social stigma improves HIV testing rates in vulnerable households in Mozambique. Based on a local social opinion survey before this study, the treatment group will receive individually-tailored information indicating supportive social opinions about HIV in their neighborhood. The primary outcome of interest is the usage of HIV-testing coupons, which will be distributed to all study participants and redeemable upon taking an HIV test in the local clinic.

Interventions

Intervention(s)
Before this study, a social opinion survey was conducted in the study communities to collect local residents' attitudes about HIV. The survey suggests that the public usually holds very supportive views towards people living with HIV and that the HIV-related stigma is less than many people had believed. Participants in this study will be asked to guess the results of the social opinion survey, and those in the treatment group will be informed of the results after that if they overestimate the HIV-related stigma in their neighborhood.

Experimental Design

Experimental Design
The potential participating households will be assigned to different study groups (treatment and control) randomly by computer before being recruited. The group assignment will be blind to enumerators. A household's group status will only be revealed at the end of the household survey. Only individuals from a treatment household will receive the intervention. All eligible individuals will receive HIV-testing coupons for themselves and for their children, regardless of which study group they are in. Instructions on how to redeem a coupon will be given at the end of the household visit.

Each coupon will be linked to an individual by a unique barcode printed on it. The study team will redeem the coupons at the collaborating clinics during a 14-day window and scan the coupons redeemed to determine usage.
Experimental Design Details
At the end of the household survey, the study team will distribute one HIV-testing coupon to each eligible adult survey respondent and each eligible children. (Adult coupons will be distributed in person, child coupons will be distributed to the primary guardian). Each coupon has a value of 50 Mts (~$0.83) and is valid 14 days. A coupon is redeemable at the designated health center when someone presents proof of HIV-testing with the coupon to the research staff on site. The payment will be made in digital cash through MPesa . There is a unique barcode on each coupon that allows the researcher to link the use of the coupon to one’s survey responses.
