ENHealthcare workers (HCWs) often experience high levels of stress, anxiety, and depression due to high workloads and responsibilities in their professional activities. Therefore, recovery from work-related stress is highly important in HCWs. The Recovery Experience Questionnaire (REQ) is a 16-item self-reported measure covering four stress recovery domains: psychological detachment from work, relaxation, mastery, and control. The current study aimed to test the REQ’s psychometric properties in a sample of Lithuanian HCWs. In total, 471 HCWs from various healthcare institutions participated in this study. Confirmatory factor analysis (CFA) was used to test the structure of the REQ. We also used the Brief Patient Health Questionnaire (PHQ-4) and the World Health Organization Psychological Well-Being Index (WHO-5) to assess the mental health of the study participants. The CFA analysis supported the correlated four-factor structure of the REQ. Furthermore, we found significant correlations between the levels of REQ and anxiety, depression, and well-being. We conclude that the REQ is a valid measure that could be a useful tool in research on HCWs’ mental health. It could also be used in healthcare settings for the evaluation of well-being among healthcare staff. Keywords: healthcare; stress recovery; occupational stress; mental health; well-being.
