BackgroundIn this study, we developed a new Korean translation for the shortened version of the Depression, Anxiety, and Stress Scale (DASS-21) and examined its psychometric properties in a Korean working population.ObjectiveTo develop a new Korean version of the DASS-21 and test its psychometric properties specific to the Korean working population.MethodsThe DASS-21 was translated to the Korean language in accordance with scientific guidelines for cross-cultural adaptation. A total of 228 general workers from Korea then completed the newly translated version of the DAS S-21 and its psychometric properties were evaluated.ResultsMost of the questionnaire items were correctly loaded on the proposed scales of the original questionnaire. Excellent internal consistency and measurement consistency over a one week interval were obtained for all scales (Cronbach's alpha; 0.87, 83, and 83, and ICC (2, 1); 0.84, 0.94, and 0.89 for depression, anxiety and stress scales, respectively). All three scales were negatively associated with the level of life satisfaction (p < 0.05).ConclusionsThe new Korean version of DASS-21 has shown excellent validity and reliability of measurement in the Korean working population. Organizations investigating the prominent health issue of affective disorders in Korean workers can use this instrument with confidence.
