A new instrument to measure healthy workplace qualities: the People in the Office Scale

This research is aimed at developing a new instrument to assess the healthy workplace qualities based on the environmental theory of stress, and ideas of salutogenic and biophilic design. A total of 319 respondents participated in the study (19–72 years; M(age) = 40.86, SD(age) = 12.70; 69% women). Additionally, nine judges were invited to evaluate the items of the scale for content validity. Using a mixed inductive/deductive method, which included literature analysis and in-depth interviews, an initial pool of 56 items was collected. From the initial pool of 56 items, the more relevant ones were selected. This list named the People in the Office Scale (POS) was subjected to a full psychometric examination. Results of the Exploratory and Confirmatory Factor Analyses show that POS has satisfactory structural and content validity, reliability, and measurement invariance across sex and age. In its final form, POS includes 27 items and five subscales: Ergonomics; Internal Communications; External Infrastructure; Freedom of Action; and Workplace as a Life Narrative. Convergent validity measured by correlating POS scores with the variables of restorative environment, workplace attachment, and organizational cynicism was satisfactory. Divergent validity measured by correlating with mental health, was also satisfactory. This new instrument can be recommended for use in both practice and research to provide evidence-based design guidance.
