Abstract
The Young Schema Questionnaire (YSQ) is a self-report measure of early maladaptive schemas and is currently in its third revision; it is available in both long (YSQ-L3) and short (YSQ-S3) forms. The goal of this study was to develop a Korean version of the YSQ-S3 and establish its psychometric properties in a Korean sample. A total of 542 graduate medical students completed the Korean version of the YSQ-S3 and several other psychological scales. A subsample of 308 subjects completed the Korean YSQ-S3 both before and after a 2-year test-retest interval. Correlation, regression, and confirmatory factor analyses were performed on the data. The internal consistency of the 90-item Korean YSQ-S3 was 0.97 and that of each schema was acceptable, with Cronbach's alphas ranging from 0.59 to 0.90. The test-retest reliability ranged from 0.46 to 0.65. Every schema showed robust positive correlations with most psychological measures. The confirmatory factor analysis for the 18-factor structure originally proposed by Young, Klosko, and Weishaar (2003) showed that most goodness-of-fit statistics were indicative of a satisfactory fit. These findings support the reliability and validity of the Korean version of the YSQ-S3.Keywords
