A $50 reward card was offered as an incentive for taking part. This allowed for a single researcher to be immersed in each data collection and analysis, thereby guaranteeing that the coding body adequately described the intentions and content of the interviews (10). First, the lead investigator thought of the transcribed information intimately and developed preliminary codes based on topics current within the semistructured questionnaire.
