Background: The Malay short version of Depressive Anxiety and Stress Scale (DASS-21) has been widely used as a tool to measure psychological parameters in studies in Malaysia. The version has been found to be reliable for clinical and non-clinical populations. Objectives: To analyse and establish the psychometric properties of the Malay version of the DASS 42-item (BM DASS-42) among medical students. Methods: Concurrent forward and backward translations of original English DASS-42 were completed. Construct validity of the DASS-42 was established by looking at its exploratory factor analysis. Malay DASS-42 and Malay HADS were administered to a total of 411 medical students. Results: Reliability of DASS-
42 revealed excellent Cronbach’s alpha values of 0.94, 0.90 and 0.87 for depressive, anxiety and stress domains respectively. Construct validity yielded 38 items out of 42 items (90%) had good factor loadings of 0.4 and more. DASS and HADS were strongly correlated for both anxiety (r=0.87) and depression (r=0.68) domains. Conclusions: The BM DASS-42 had admirable psychometric properties among the tested population. Further studies are needed to verify these preliminary outcomes in other Malaysian subjects.
Introduction: There is an appealing need to have a validated Bahasa Malaysia (BM) questionnaire that is able to gauge stress coping styles among Malaysian population. A culturally accepted questionnaire will generate further research in the aspect of stress coping patterns in the Malaysia population. Objective: To translate the Coping Inventory for Stressful Situations (CISS) questionnaire into BM and to determine the construct validity, reliability and other psychometric properties of the translated BM version of the English CISS 48-item. Method: Two parallel forward and backward translations were done in BM in accordance to guideline and its validation was determined by using confirmatory factor analysis among 200 Malaysian subjects. Results: The BM CISS had very good Cronbach’s alpha values, 0.91, 0.89 and 0.85 respectively for Task-, Emotional- and Avoidance-oriented. The overall Cronbach’s alpha was 0.91. It also had good factor loading for most of its items where 44 items out of 48 had Confirmatory Factor Analysis values of more than 4.0. Conclusions: BM CISS had been adequately and correctly translated into Bahasa Malaysia with high psychometric properties. Minimal readjustment may be required in a few of its items to obtain excellent results.
