RECRUITMENT
Participants were recruited via email and Facebook/Instagram ads through the clientele of a community and a private clinic that offer help to individuals with ED. The recruitment ad specified that the study targeted individuals with behaviors fitting binge eating disorder and included a description of binge eating. Participants completed a questionnaire on an online platform (Qualtrics Research Suite), available between October 2020 and July 2021. All participants gave informed consent by clicking on a button indicating that they had read the study description, agreed to participate voluntarily in the study, and were 18 years or older. They were then redirected to the questionnaires that required approximately 50 min to complete. At the start of the questionnaire, participants were asked whether they had experienced frequent and sustained episodes of binge eating in the last 5 years. If they indicated that they had not, they were automatically redirected at the end of the questionnaire and thanked for their participation. This provided an additional safeguard against the inclusion of individuals who did not meet the binge eating criterion. The questionnaires were started 405 times and completed by 62.47% participants. Ethical approval for the project was obtained from the Ethics Committee for Research in Health Sciences of the Université Laval (September 8, 2020, #2020-230/08-09-2020).
