2.2. Recruitment and consent

The Amsterdam School of Communication Research (ASCoR) (2022‐PC‐14489) and the board of the Medical Ethical Committee of the Amsterdam UMC; location AMC; Amsterdam (W22_032 # 22.062) approved this study.

To generate a heterogeneous sample of HCPs, purposive and snowball sampling were used. Researchers (B. S., J. S., J. W.) contacted their respective networks of HCPs through email, where the researchers briefly stated what the project entailed. Those interested were then referred to the primary researcher (B. C.) who emailed them with an information letter and informed consent form. Interested participants were then forwarded to trained research assistants to schedule the interviews. Other participants were recruited via snowball sampling by asking participants about other HCPs who treat migrant patients and may be interested in participating in this study. These potential participants were then contacted the same way as with the purposive sampling method. All participants gave written informed consent.
