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 out-patient clinics. Results: There were 54 participants in this study. The subscale (attitude towards psychotropic medications) has a Cronbach's α of 0.93, whereas the subscale that assesses the presence of side effect problems has a Cronbach's α 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 (X2 (36) = 281.8, p <0.001).
Conclusion:
In conclusion, MDAI-9 is reliable and valid.
