An informatized survey was sent to the hospitals participating in this study. Nurses responded to the same survey at each data gathering point. The French speaking Swiss sample and the French sample responded 4 times to the questionnaire (T0: February/March 2021; T1: October/November 2021; T2: March/April 2022; T3: September/October 2022), whereas the German-speaking Swiss sample, the Canadian and the Portuguese sample responded only three time to the questionnaire (T0: November 2021; T1: April/March 2022; T2: September/October 2022). Finally, the sample from Belgium only responded to the questionnaire once (April/May 2022).
The survey included the following questionnaires:
Demographic questions (Gender, age, marital status, number of children, date since graduating as nurse, activitiy rate)
Degree of exposition to COVID
Perceived Stress Scale (PSS): measure of perceived stress
WHO Quality of Life questionnaire (WHOQOL): Questionnaire evaluating general quality of life
BRIEF-COPE: Measure ways to cope with a stressful life-event
Post-Traumatic Growth Inventory (PTGI): Measure the level of post-traumatic growth in person which survived a traumatic event
Connor-Davidson Resilience Scale (CD-RISC): Measure resilience
Multidimensional Scale of Perceived Social Support (MSPSS): Measure individual perception of support
COPSOQ: Evaluate psychosocial conditions in the work place
SISI: Single 7-point Likert scale measuring sense of identification with the profession
Nursing Stress Scale (NSS): Measure degree of stress experienced by nurses
Workplace Wellbeing: In-house questionnaire about workplace wellbeing
The Nursing Stress Scale was only presented at T1, T2 and T3. It was thus not presented at all to the Belgian sample.
The general methodology is described in the article present in the references section (Ortoleva et al. 2021)
