Data collectors
RECRUITMENT, BLIND
Local women who lived in adjoining neighborhoods were recruited and trained as data collectors. These isiXhosa-speaking women also spoke English, typically had a 12th grade education, and were selected based on their good social skills, the ability to engage peers, and the responsibility and ability to complete interviews on a digital platform. Data collectors were assigned to clinics during the recruitment period and then conducted all assessments in the participants’ home or outdoors if there was no privacy in the home. Data collectors were blind to intervention condition but may have realized intervention status over time, based on mothers’ answers to assessment questions.
