To examine the reliability and construct validity of the Malay Version of the Depression Anxiety Stress Scales (DASS), a validation study was conducted in 184 automotive assembly workers. The internal consistency and construct validity were assessed using Cronbach's alpha coefficient
and exploratory factor analysis. The Cronbach's alpha coefficients for DASS-Depression, DASS-Anxiety and DASS-Stress were 0.91, 0.88 and j 0.89, respectively, indicating satisfactory internal consistency Exploratory factor analysis showed three meaningful common factors that could
explain the three theoretical constructs of this instrument. These results suggested that the Malay version DASS is reliable and valid for assessing, the self perceived depression, anxiety and stress among Malaysian automotive workers.
