**4.3 Procedure**

Participants were recruited in two ways. First, gender and sexuality alliances (GSAs) were contacted through Instagram, (response rate = 45%). Second, Dutch SGM-related Instagram accounts, such as Amsterdam Pride, were approached (response rate = 39%). To ensure the anonymity of those interested in participating in the study, all could apply directly through Instagram or e-mail, and did not have to apply through the institution. The selection criteria for participation were stated in the call for participation. Applicants for participation were further informed on the study through an information letter.
