Objective: The present study aimed to examine the psychometric validity and reliability of the Korean version of the Distress Overtolerance Scale (K-DOS) in a clinical psychiatric sample.
Methods: Participants were 267 psychiatric outpatients recruited from the Dept. of Psychiatry at Hanyang Univ. Guri Hosp. They completed the Korean version of the Distress Overtolerance Scale (K-DOS), along with validated Korean versions of the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Beck Hopelessness Scale (BHS), and the Ruminative Response Scale (RRS). Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to examine the factor structure of the K-DOS. Internal consistency was assessed using Cronbach’s alpha and item-factor correlations. Convergent validity was evaluated through correlations with depression, anxiety, hopelessness, and rumination.
Results: EFA revealed a two-factor structure for the K-DOS, which was supported by CFA with acceptable model fit indices (CFI = .95, TLI = .94, GFI = .91, RMSEA = .08, SRMR = .07), confirming its factorial validity. The two factors were interpreted as (1) Tendency to Harm Oneself and (2) Fear of Negative Evaluation. Internal consistency was good, with Cronbach’s alpha coefficients of .85 and .81 for each factor. Significant positive correlations with depression, anxiety, hopelessness, and rumination supported the convergent validity.
Conclusion: These findings suggest that the K-DOS is a reliable and valid instrument for assessing distress overtolerance in psychiatric populations and may be useful in both clinical assessment and research.
