Background

The 10-item Perceived Stress Scale PSS-10 is one of most widely used instruments to measure a global level of perceived stress in a range of clinical and research settings. This study was conducted to examine the psychometric properties of the Simplified Chinese version of the PSS-10 in policewomen.

Methodology

A total of 240 policewomen were recruited in this study. The Simplified Chinese versions of the PSS-10, the Beck Depression Inventory Revised BDI-II, and the Beck Anxiety Inventory BAI were administered to all participants, and 36 of the participants were re-tested two weeks after the initial testing.

Principal Findings

The overall Cronbach-s alpha was 0.86, and the test–retest reliability coefficient was 0.68. Exploratory Factor Analysis EFA yielded 2 factors with eigenvalues of 4.76 and 1.48, accounting for 62.41% of variance. Factor 1 consisted of 6 items representing -negative feelings-; whereas Factor 2 consisted of 4 items representing -positive feelings-. The item loadings ranged from 0.72 to 0.83. The Confirmatory factor analysis CFA indicated a very good fit of this two-factor model to this sample. The PSS-10 significantly correlated with both BDI-II and BAI, indicating an acceptable concurrent validity.

Conclusions

The Simplified Chinese version of the PSS-10 demonstrated adequate psychometric properties for evaluating stress levels. The results support its use among the Chinese population.
