2.2. Procedure

The current data were collected using a secured web-based self-report survey following established guidelines for web-based surveys [32]. PSP were recruited through public safety organizations by means of social media, organizational websites, unions, and emails sent via employers, professional associations, and researchers as well as organizational listservs. The former Minister of Public Safety and Emergency Preparedness in Canada also provided support for the survey through an online video that served to assist with recruitment. The survey issued each participant a unique computer-generated random code that allowed for repeated non-duplicate entries, therein accommodating PSP schedules and facilitating participation. The study received approval from the University of Regina Institutional Research Ethics Board (File No. 2016-107).
