The purpose of the current study was to examine the reliability and validity of the Korean version of the Perceived Stress Scale-10 (K-PSS-10). After translation and back-translation of the original PSS-10, a convenience sample of 342 community-dwelling older adults was recruited from senior community centers. Data were analyzed using factor analysis, Pearson's correlation coefficient, and Cronbach's alpha. Using factor analysis with principal axis factoring with oblimin rotation, two factors were extracted. The two-factor solution explained 49.71% of the total variance. Internal consistency values for negative and positive subdomains were 0.87 and 0.71, respectively. Moderate relationships were found between a negative response to stress and depression (r = 0.42, p < 0.001) and quality of life (r = -0.45, p < 0.001). A positive response to stress had moderate significant correlations with depression (r = 0.30, p < 0.001) and quality of life (r = -0.36, p < 0.001). Overall, the K-PSS-10 had good reliability, with a Cronbach's alpha of 0.75. The K-PSS-10 demonstrated the desired psychometric properties and was easy to use to assess the stress of community-dwelling older adults in Korea.
