Abstract: ObjectiveTo assess the reliability and validity of the Chinese version of Perceived Stress Scale (PSS-10).MethodsA total of 272 participants, including patients with depression and obsession and healthy volunteers, were selected and tested by the Chinese version of PSS-10, Beck Depression Inventory-II (BDI-II), and Beck Anxiety Inventory (BAI). Thirty patients were randomly selected and retested by PSS-10 after 2 weeks.ResultsThe overall Cronbachs alpha of the Chinese version of PSS-10 was 0.91 and the test-retest reliability coefficient was 0.69 (P<0.05). The exploratory factor analysis (EFA) yielded two factors, i.e. the negative feelings (6 items) and positive feelings (4items). The confirmatory factor analysis (CFA) indicated that the fitting of the two factor model was perfect (χ2=44.52，P<0.107). The total score of PSS-10 significantly and positively correlated with scores of both BDI-II and BAI (P<0.01). The differences of scores of PSS-10 of three groups were significant (F=107.6，P<0.01). ConclusionThe reliability and validity of the Chinese version of PSS-10 are good and can be used as a self rating tool to assess the level of perceived stress.
