The Individual- and Organization-Related Stressors in Pandemic Scale for Healthcare Workers (IOSPS-HW): Development and Psychometric Properties of a New Instrument to Assess Individual and Organizational Stress Factors in Periods of Pandemics

The validation and psychometric properties of the Individual and Organization related Stressors in Pandemic Scale for Healthcare Workers (IOSPS-HW) were presented. This is a new measure to assess individual factors related to the health and well-being of individuals, such as family and personal relationships, as well as organizational factors related to the management of the pandemic, including workplace relationships, job management and communication. Across two studies conducted at different time points of the pandemic, psychometric evidence of the IOSPS-HW is presented. In Study 1, through a cross-sectional design, we conducted exploratory and confirmatory factor analysis through which the originally developed 43 items scale was reduced to a 20-item bidimensional scale with two correlated dimensions: Organization-related Stressors (O-S; 12 items) and Individual- and Health-related Stressors (IH-S; 8 items). Internal consistency and criterion validity were also provided by investigating the relationship with post-traumatic stress. In Study 2, we provided evidence for the temporal invariance of the measure and for temporal stability through a Multigroup-CFA through a longitudinal design. We also supported the criterion and predictive validity. The results suggest that IOSPS-HW is a good instrument to simultaneously investigating individual and organizational factors related to sanitary emergencies in healthcare workers.
