Validation of the Malay Translation of Drug Attitude Inventory

Introduction: The Drug Attitude Inventory 9 (DAI-9) is a nine -item self -rated questionnaire. The questionnaire assessed positive and negative attitudes of patients toward taking medication, presence of medication side effects and perceived autonomy in treatment decision. Aim : This study aimed to validate the psychometric properties of the Malay translation of Drug Attitude Inventory 9 (MDAI-9). Method: DAI-9 was translated from English to Malay via forward and backward translation process to produce MDAI-9. MDAI-9 was then validated on patients with psychosis who were attending psychiatry outpatient clinics. Results : There were 54 participants in this study. The subscale (attitude towards psychotropic medications) has a Cronbach's alpha of 0.93, whereas the subscale that assesses the presence of side effect problems has a Cronbach's alpha of 0.86 . Exploratory factor analysis supported a two -factor model. Kaiser-Meyer-Olkin's measure of sampling adequacy was 0.64 and Bartlett's test of sphericity was significant (X (2) ((36)) = 281.8, p <0.001). Conclusion: In conclusion, MDAI-9 is reliable and valid.
