Psychometric Properties of the Depression, Anxiety, Stress Scales-21 (DASS-21) in a Greek Sample

Abstract

The aim of this study is to evaluate the psychometric properties of the DASS-21 in a non-clinical sample of the Greek population. The Depression Anxiety Stress Scales 21 (DASS-21) is a self-report instrument measuring anxiety, depression and stress. The validation was carried out in a sample of 12,868 Greek adults, ranging from 18 to 65 years old. Results showed that the DASS21 has satisfactory reliability and validity indexes. Moreover, the factorial structure of the scale matches the ones found in previous studies in many countries. The results of this study suggest that the Greek DASS-21 can be used as a reliable and valid instrument for the measurement of depression, anxiety and stress in the Greek population.
