“…We collected data using four questionnaires: the Impact of Event Scale – Revised (IES - R), the Depression, Anxiety, Stress Scale (DASS – 21), the Professional Quality of Life scale (ProQoL), and the Intent to Turnover scale (Creamer, Bell, Falilla, 2002; Lovibond, Lovibond, 1995; Stamm, 2012 ). These scales have demonstrated strong reliability and validity when used in previous nursing studies, including with CCN participants ( McMahon et al, 2016 , Maunder et al, 2004 , Jiang et al, 2021 ). Previously used to assess the impact of a public health crisis, the IES – R measures the psychological impact of an event, providing a brief snapshot in time of staff response to crisis, and capturing symptoms of post-traumatic stress disorder (PTSD) ( Wang et al, 2020 , McAlonan et al, 2007 , Weiss, 2007 ).…”
