Primary Outcomes (End Points) We consider the two outcome variables that are directly observed by our project staff to be primary outcomes of interest: 1. HIV testing 2. School attendance We consider the following outcome variable to be primary outcome of interest: HIV testing at the household level (binary outcome)
Primary Outcomes (Explanation) HIV testing: an indicator that at least one of a household’s HIV testing coupons has been redeemed. This is a household-level variable equal to 1 if at least one of a household’s incentive coupons is presented at the local health clinic for the HIV testing incentive payment before the 14-day deadline, and 0 otherwise. School attendance: an indicator for a child attending school. This is an individual-level variable equal to 1 if a child is directly observed to be attending school by our project staff in an unannounced school visit, and 0 otherwise. The outcome variable of primary interest is HIV testing at the household level. This will be a binary outcome indicating that the household either self-reports having had or is directly observed by our survey staff having an HIV test upon our recommendation. This outcome captures the combination of having already had an HIV test, as well as openness to recommendations for future testing, both of which may be influenced by exposure to the FCC program. To be specific, the component variables of this outcome variable are: - HIV testing (self-reported): an indicator that anyone in the household has been tested for HIV in the last 12 months. This is a household-level variable equal to 1 if at least one household member is reported to have had an HIV test in the last 12 months, and 0 otherwise. - HIV testing (directly observed): an indicator that at least one of a household’s HIV testing coupons has been redeemed. This is a household-level variable equal to 1 if at least one of a household’s incentive coupons is presented at the local health clinic for the HIV testing incentive payment before the 14-day deadline, and 0 otherwise. Our composite HIV testing outcome is therefore equal to 1 if HIV testing (self-reported) is equal to 1 or HIV testing (directly observed) is equal to 1, and 0 otherwise.
Experimental Design (Public) The study uses a three-stage randomized controlled trial (RCT) methodology. Stage 1: communities were randomly assigned to treatment or control status (inclusion in or exclusion from the FCC program). Stage 2: a subset of households within FCC treatment communities were randomly assigned to a strong encouragement to participate in FCC programs (“directly enrolled” households). These directly enrolled households receive a home visit by an FCC program community worker and are assessed for inclusion in various FCC subcomponent programs. Stage 3: as part of the endline survey, households in all communities (treatment and control) are randomly assigned to treatments to improve information about HIV, information about HIV treatment (antiretroviral therapy, or ART), and to reduce concerns about HIV-related stigma. The study uses a three-stage randomized controlled trial (RCT) methodology. Stage 1: communities were randomly assigned to treatment or control status (inclusion in or exclusion from the FCC program). Stage 2: a subset of households within FCC treatment communities were randomly assigned to a strong encouragement to participate in FCC programs (“directly enrolled” households). These directly enrolled households receive a home visit by an FCC program community worker and are assessed for inclusion in various FCC subcomponent programs. Stage 3: as part of the endline survey, households in all communities (treatment and control) are randomly assigned to treatments to provide information about HIV, provide information about HIV treatment (antiretroviral therapy, or ART), provide both HIV and ART information, reduce concerns about HIV-related stigma, and receive higher compensation for getting an HIV test.
Sample size (or number of clusters) by treatment arms Randomization Stage 1: 76 communities as clusters (38 treatment, 38 control). 60 households in each community are included in survey sample. Randomization Stage 2: 35 households in each treatment community randomly assigned to direct enrollment in FCC program; 25 in each treatment community are controls (not assigned to direct enrollment). Randomization Stage 3: 25% of households assigned to each of four treatment conditions (HIV information, ART information, anti-stigma, and control). Randomization Stage 1: 76 communities as clusters (38 treatment, 38 control). 60 households in each community are included in survey sample. Randomization Stage 2: 35 households in each treatment community randomly assigned to direct enrollment in FCC program; 25 in each treatment community are controls (not assigned to direct enrollment). Randomization Stage 3: equal share of households assigned to each of six treatment conditions (HIV information, ART information, both HIV and ART information, anti-stigma, high incentive for HIV testing, and control).
