Sampling for the qualitative component
Qualitative data were collected from one intervention group in the study, at one of the three CLC sites. The study site was chosen for logistical convenience. Of the nine mother–child pairs who consented to participate, one withdrew due to relocation. Participants at the selected CLC site were consented in-person to additional participation in the qualitative study at the time of consent to the RCT. They gave an additional signature on an RCT consent form with a qualitative section. To prioritize ethical considerations, participants’ ability to withdraw from the qualitative or RCT study was emphasized. No additional compensation was given for this sub-study.
