Trustworthiness criteria

Criteria	Performed techniques and application procedures
Credibility	Researcher triangulation: each interview was analyzed by 2 researchers. Team meetings were held in which the analyses were compared, and subthemes and themes were identified. Triangulation of data collection methods: semistructured interviews were conducted, and field notes were kept by the researchers. Participant verification: all transcripts were returned to participants for feedback. None of the participants made any additional adjustments.
Transferability	Detailed descriptions of the study conducted included the characteristics of the research team and the participants, sampling strategies, and the data collection and analysis process.
Reliability	External researcher audit: an external researcher evaluated the research protocol, focusing on aspects related to the study methods and design. In addition, the external researcher specifically verified the descriptions of the participant quotes, the codes, the subthemes and the themes.
Confirmability	Researcher triangulation, participant verification, and triangulation of data collection methods. Researcher reflexivity was encouraged through reflective reporting and description of the study.
