Data collection
Collection of data was carried out between May 2023 and June 2023. The lead researcher together with four research assistants carried out the data collection. The research assistants received training before commencement of data collection on the identification of eligible participants, obtaining informed consent, and conducting the interviews. The inclusion-exclusion criteria were used to identify potential study participants after which the researcher gave a detailed explanation of the aim of the study to the participants and what was required of them. The participants were then asked for their informed consent. After receiving consent, a physical interview was carried out with the research subjects using a pretested questionnaire which captured their bio-data and other relevant information of interest to the study.
