The safety attitudes questionnaire for out-of-hours service in primary healthcare-Psychometric properties of the Croatian version

The aim of the study was to assess the reliability and construct validity of the Croatian translation of the Safety Attitudes Questionnaire-Ambulatory version (SAQ-AV) in the out-of-hours (OOH) primary care setting. A cross-sectional observational study using anonymous web-survey was carried out targeting a convenience sample of 358 health professionals working in the Croatian OOH primary care service. The final sample consisted of 185 questionnaires (response rate 51.7%). Psychometric properties were assessed using exploratory hierarchical factor analysis with Schmid-Leiman rotation to bifactor solution, McDonald's omega, and Cronbach's alpha. Five group factors were identified: Organization climate, Teamwork climate, Stress recognition, Ambulatory process of care, and Perceptions of workload. Items loading on the Stress recognition and Perceptions of workload factor had low loadings on the general factor. Cronbach's alpha ranged between 0.79 and 0.93. All items had corrected item-total correlation above 0.5. McDonalds' omega total for group factors ranged between 0.76 and 0.91. Values of omega general for factors Organization climate, Teamwork climate, and Ambulatory process of care ranged between 0.41 and 0.56. McDonalds' omega general for Stress recognition and Perceptions of workload were 0.13 and 0.16, respectively. Even though SAQ-AV may not be a reliable tool for international comparisons, subsets of items may be reliable tools in several national settings, including Croatia. Results confirmed that Stress recognition is not a dimension of patient safety culture, while Ambulatory process of care might be. Future studies should investigate the relationship of patient safety culture to treatment outcome.
