Abstract

Introduction: The Depression Anxiety Stress Scales (DASS-21) is an instrument that assesses the negative emotional states of depression, anxiety, and stress. Aim: The aim of this study was to psychometrically evaluate a Polish version of the brief 21-item version of the DASS. Material and Methods: A 212 medical students who fully completed the DASS-21 questionnaire were included in the study. Validity was evaluated through the analysis of construct validity and reliability. Results: The Cronbach's alpha for the overall score was 0.93 and for the three subscales were: Stress 0.85, anxiety 0.80, depression 0.86. The exploratory factor analyses identified three dimensions in a modified version of the DASS-21 (renamed DASS-18), with appropriate construct validity and good reliability. The three dimensions accounted for over 60%, 68% of variance between items. Conclusion: Internal consistency of the Polish version of the DASS-21 as a whole and for each of three originally developed subscales was excellent. We supported the three-factor model of the DASS. The modified DASS-18 scale obtained in this study is measure of depression, anxiety and stress, with acceptable reliability and construct validity, but it requires confirmation in the next study.
