Do Nurses Thrive in Their Organization? Validation of the Short Form of Nurses’ Organizational Health Questionnaire

<b>Background/Aim:</b> The quality of care provided to patients was closely related to the nursing staff's well-being and their experience within the organization. This study aimed to evaluate the psychometric properties of the short form of the Nurses' Organizational Health Questionnaire (QISO-SF), with a focus on its relevance for assessing nurses' organizational well-being in healthcare environments. The study examined the instrument's structural validity and internal consistency. <b>Methods:</b> A secondary analysis was conducted using data from three cross-sectional studies, including 1279 nurses providing direct patient care across various Italian healthcare settings. Dimensionality of the QISO-SF was tested via confirmatory factor analysis (CFA), and reliability was assessed using ordinal omega coefficients (ω). <b>Results:</b> The QISO-SF comprises 48 items across 11 dimensions, grouped into 5 scales: Comfort, Organizational Context and Relational Processes, Workload, Positive and Negative Indicators, and Psychophysical Distress. The instrument demonstrated good structural validity (RMSEA = 0.048-0.094; CFI = 0.967-0.994) and satisfactory reliability (ω = 0.644-0.857). By maintaining the theoretical framework of the original questionnaire while reducing completion time, the short form is suitable for evaluating nurses' work-related quality of life and organizational well-being. <b>Conclusions:</b> The QISO-SF is a concise, reliable, and valid tool to assess work-related quality of life and Organizational health in nursing professionals. Its use can support interventions aimed at promoting well-being in healthcare settings.
