Validation of the Malay Translation of Drug Attitude Inventory

Abstract

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 (​​​​​X 2 (36) = 281.8, p <0.001). Conclusion:In conclusion, MDAI-9 is reliable and valid.

Technology-Based Strategy to Improve Medication Compliance Among Patients With Schizophrenia Spectrum Disorders

“…It is a valid and reliable tool with good internal consistency (α = 0.7). The items on the original DAI-9 were constructed based on the understanding that compliance was influenced by the patients' positive and negative attitudes toward the medication [28]. A positive sum score < 11 is defined as a negative attitude to medication while a negative sum score >7 suggests a side effect problem [28].…”
