DASS-21 is the short version of the Depression, Anxiety and Stress Scale-42 (DASS-42) developed by Lovibond and Lovibond. The Turkish adaptation of the scale was made by Sarıçam. The 4-point Likert-type scale includes a total of 21 items consisting of three sub-dimensions: depression, anxiety and stress. In the normal sample, test-retest reliability coefficients were found to be r=0.68 for depression, r=0.66 for anxiety and r=0.61 for stress. An individual's score of 5 and above on the depression sub-scale, 4 and above on the anxiety sub-scale and 8 and above on the stress sub-scale is interpreted as indicating the relevant psychological problem.
