The participating employers represented a non-random,
convenience sample drawn from existing researcher contacts,
institutional ties, and past collaborations. Supervisors were invited to participate in the study through their
employer via email. The email invitation included a webbased
Universal Resource Locator link that participants
clicked to take them to the online questionnaire and casevignette.
The survey took approximately 15–20 min to
complete and consent to participate was completed during
the process. Non-respondents received up to four reminder
e-mails sent weekly to complete the survey.
