This study investigated the reliability and validity of the DAS-A in a sample of 308 Chinese adults in Hong Kong.


The reliability of the DAS-A and its relevant sub-scales was measured using internal consistency (Cronbach's alpha) and Guttman split-half reliability. Principal components analysis was performed to assess construct validity. Discriminant validity of the DAS-A was performed by examining whether the DAS-A could discriminate between the depressed and the non-depressed subjects in this study.


The split-half reliability of the DAS-A was found to be r = 0.87; Cronbach's alpha was 0.945; and item-total correlations ranged between 0.36 and 0.75. Factor analysis revealed three factors that were similar to those that were found in other studies: Performance Evaluation, Need for Approval, and Anaclitic Self-Esteem. Discriminant validity suggested that the DAS-A discriminated successfully between the non-depressed and the depressed groups. Nevertheless, some differences were noticed in the relative strength of the factors and in the distribution of the scale items into the three factors.


It was hoped that with this type of cross-cultural information, the universality of the constructs of the DAS-A could be reliably demonstrated.
