title: Psychometric testing of the Depressive Cognition Scale in Korean adults.
abstract: This study translated the Depressive Cognition Scale (DCS) from English into Korean and tested the reliability and validity of the scale. Data were from a convenient sample of 795 community-dwelling Korean adults with a self-administered questionnaire. With regard to the reliability estimate, the internal consistency of the Korean version of the DCS (K-DCS) was acceptable, where the Chronbach's alpha is .93 and the average item-to-total correlation r = .760. With regard to the validity estimate, the mean scores of the K-DCS were significantly different according to gender, age, and marital status. A single factor was extracted that accounted for 67.37% of the total variance. The average score of the K-DCS also correlated significantly with the subscales of the Korean version of the Profile of the Mood States Brief Form. These findings suggest that the K-DCS can be used as a reliable and valid measure of depressive cognition among Korean adults.
