The research assistants were recruited from a community based organisation called Child Protection Society (CPS). These research assistants are known as voluntary lay workers (VLWs), and have been trained in research and ethics. They have also been involved in research several times. The VLWs were trained on the protocol by the PI. A VLW assignment form will be filled in when allocating a VLW to a participant. The VLW has to reside in the same community as the participant.
