WHAT THE TEST MEASURES

About This Assessment

Treatment Attitude Questionnaire, DAI-30 Test

Drug Attitude Inventory (DAI-30) Test

compliance psychopathology

This self-report measure is used to characterize a patient’s subjective attitudes toward prescribed psychotropic medication. The Drug Attitude Inventory (DAI-30) helps clinicians identify favorable versus unfavorable beliefs and experiences that may be associated with motivation to continue treatment.

Developed by Thomas R. E. Barnes, Steven C. Hogan, and Robert P. Awad, it consists of 30 items and typically takes about 6 minutes to complete. Responses are intended to support clinical formulation by highlighting themes such as perceived benefits, concerns, or resistance related to medication use.

In practice, the Drug Attitude Inventory (DAI-30) may be used alongside interview and adherence history to guide patient-centered discussion, address barriers to engagement, and inform treatment planning.
