Ethics approval and consent to participate
: Prior to implementation of this study, ethical approval was sought and obtained from Thammasat University’s Human Ethics Sub-committee #3 on August 10, 2016. Prior to each interview, written informed consent was obtained from all participants. Two participants lacked the literacy necessary to read the consent form and provide a signature; in these cases, the consent form was read to them by the interpreter, and their thumb print was obtained to signify consent. This accommodation was explicitly described in the proposal approved by the Sub-committee. There was full disclosure regarding the purpose of the research, the nature of the questions to be asked, potential risks, and the intended use of the data. All participants were advised that they could end the interview at any time without repercussions, and they were observed throughout the interviews for any signs of distress.
