Reliability and validity of the Japanese version of the Perceived Stress Scale

要旨

Psychometric characteristics of the Japanese version of the Perceived Stress Scale (PSS), a popular measure of general stress, were investigated. There are two versions in the PSS: the 14-item version and the 10-item version with four items removed from the 14-item version. The PSS was completed by 852 undergraduate and graduate students. In addition, 435 participants in this sample also completed the Daily Hassles Scale, the Hopelessness Scale, and Somatization, Depression, and Anxiety subscales of the Hopkins Symptoms Checklist. All scales with the exception of the Daily Hassles Scale were administered again three weeks later. As expected, the two-factor model was supported for both versions of the PSS by confirmatory and exploratory factor analysis. Good internal consistency and test-retest reliability were found with both versions. Correlations between the PSS and the other scales indicated the independence of the PSS, and the predictability of psychological distress by using the PSS.
