Abstract: BACKGROUND:While the psychosocial work environment within the hospital sector is a topic of great debate, surveys assessing stress often do not differentiate between stress related to work- and private life. Identifying risk factors associated with these domains of daily life would help improve policies as well as target relevant treatment options. Therefore, the aim of this study was to evaluate associations between stress during to work- and private time with Cohen’s Perceived Stress Scale (CPSS). METHODS:Perceived stress was assessed by the full version of CPSS (scores 0–40) as well as by two single-item questions related to stress related to work- and private life, respectively. Associations between these single-items and CPSS were modelled using general linear models controlling for lifestyle factors. RESULTS:Overall, stress due to both work- and private time was strongly associated with CPSS scores. In the full population (n = 3,600), “never experiencing stress” during both work- and private time was associated with low stress scores (6.0, 95%CI 5.1–6.9). “Never experiencing” work-related stress but experiencing private time stress “very often” was associated with high stress scores (22.4, CI 19.8–25.1). Likewise, experiencing work-related stress “very often” but “never experiencing” private time stress was also associated with high stress scores (22.2, CI 20.3–24.2). Lastly, Spearman’s r between the full CPSS and the two single-item questions about work- and private time stress were 0.62 (p < 0.0001) and 0.52 (p < 0.0001), respectively, while the two items were only weakly correlated (r = 0.32). CONCLUSION:The present study shows that perceived stress due to both work and private time is strongly associated with Cohen’s Perceived Stress Scale scores. The results illustrate the feasibility of using single-item questions related to work- and private time in identifying domain-specific risk factors for psychosocial stress.
