After completing the study materials and having obtained permission from the MoH research unit and both of the facilities involved, the research team selected and trained data collectors. The selection criteria for data collectors involved having a multi-disciplinary team including one social scientist and one health worker with adequate experience in conducting health-related research. The research team was gender balanced, comprising two female and two male members. The data collectors were trained in the various methodologies of data collection and also on critical ethical issues. As part of the training, the data collectors participated in pre-testing the instruments with the guidance of the principal investigator.
