Experimental: Behavioral Intervention Using Social Norms and Priming
Patients in this arm may have been exposed to the behavioral intervention, which included the following components: 1) visual feedback about clinic-level retention in care through an interactive poster; 2) a self-relevant priming image that appeared on all components; and 3) a take-home item (i.e., pillbox or calendar) with the priming image.
The intervention includes a clinic-based component and a take-home component. All components include the priming image of a Baobab tree. The clinic-based component is an interactive poster that rewarded appointment attendance. Patients who attend three consecutive on-time visits are congratulated and given a colored sticker to place on a poster that is publicly displayed at the clinic. In one clinic, the take-home component is a 2015 calendar in Kiswahili that contained the priming Baobab image. In the other clinic, the take-home component is a small plastic pillbox featuring the Baobab logo.
- Retention in care, defined as an attended visit between 150-210 days after the baseline visit [ Time Frame: 6 months ]This measure of retention in care accounts for variability in visit scheduling by individual providers and therefore uses a window period of 150-210 days to determine whether the patient was in care at 6 months
- >=95% medication possession ratio (MPR) [ Time Frame: 6 months ]MPR is a measure of ART adherence that is correlated with viral suppression
- The proportion of scheduled visits that were completed during the 6-month observation period [ Time Frame: 6 months ]
- Medication possession ratio (MPR), continuous scale [ Time Frame: 6 months ]
