Abstract


Background: Cultural awareness and its implications in assessment is becoming an important issue in mental health. Recent studies examining this issue have found that the psychometric properties of some commonly used assessment instruments may vary considerably, especially when administered to people who have English as a second language.

Objective: To examine the factor structure of the Thai Depression Anxiety and Stress Scales (DASS-42) using internal consistency and confirmatory factor analysis.

Methods: The Thai DASS-42 was administered to a non-clinical sample of Thai women (N = 300) residing in various metropolitan areas of Sydney. The findings were compared with the data of a Thai-speaking sample (N = 502) in Bangkok for validation compared with the English version by Lovibond and Lovibond.

Results: Confirmatory factor analysis showed that the Thai DASS-42 discriminates between depression, anxiety and stress, but the extent of differentiation between these negative emotional disorders was less in comparison with the English DASS. Moreover, the Thai DASS-42 showed less discrimination between the three scales in an Australian Thai-speaking sample in comparison with a normal Thai-speaking sample in Bangkok (N = 502). In general, the factor loadings for all 42 DASS items in the Australian Thai-speaking sample were comparable with those in both the English-speaking and the Bangkok samples, and indicated that the items had been adequately and appropriately translated and adapted. The Thai DASS-42 demonstrated significant means and standard deviations (SD) 5.02 (7.37), 5.01 (6.51) and 7.52 (8.63) respectively for depression, anxiety and stress subscales with significant factor loading values.

Conclusions: The Thai DASS-42 was found to have sound psychometric properties and to be a suitable tool for use among Thai women living in Sydney. The present findings will help guide further preventative research in examining indications of subclinical anxiety and depression.
