    Abstract

    Objectives

    This study was conducted to examine the reliability and validity of the Dimensional Obsessive-Compulsive Scale-Korean version (DOCS-K).

    Methods

    Fifty four individuals with obsessive-compulsive disorder (OCD) completed a battery of measures including the DOCS-K, Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Obsessive-Compulsive Inventory-Revised-Korean version (OCI-R-K), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). Psychometric properties of the DOCS-K were analyzed.

    Results

    The Cronbach's α value for internal consistency of DOCS-K was in excellent range (0.91-0.95). The construct validity was analyzed on the basis of principal component analysis and 4-factor structure of the original scale was maintained. The DOCS-K total and subscale scores were more strongly correlated with those of other OC symptom-specific measures (convergent validity) than those of nonspecific depression or anxiety measures (discriminant validity). The DOCS-K total score was strongly correlated with total scores of Y-BOCS (r=0.64, p<0.01) and OCI-R-K (r=0.71, p<0.01). Correlations between the DOCS-K subscales and corresponding subscales of the OCI-R-K were stronger than correlations with the noncorresponding subscales : 1) DOCS-K Contamination and OCI-R-K Washing (r=0.69), 2) DOCS-K Responsibility and OCI-R-K Checking (r=0.54), 3) DOCS-K Unacceptable Thoughts and OCI-R-K Obsessing (r=0.73), 4) DOCS-K Symmetry and OCI-R-K Ordering (r=0.55).

    Conclusion

    This study revealed that the DOCS-K has good reliability and validity. Therefore, the DOCS-K can be used as a promising measure of dimensional OC symptoms in Korea.
