Abstract
ABSTRACT. Background: To the best of our knowledge, there is no validated instrument for measuring knowledge of psychiatric aspects of alcohol use disorder (AUD) amongst medical students. Our aim was to develop an instrument for this purpose and to describe the instrument's psychometric properties. We also investigated whether the instrument could demonstrate a significant change in scores following an educational intervention consisting of a 60-minute PowerPoint lecture on AUD, associated handouts, and role-plays. Methods: The Knowledge of Psychiatric Aspects of Alcohol Questionnaire (KPAAQ) was developed from the Kaplan and Saddock textbook synopsis chapter on alcohol related disorders. The questionnaire included 6 categories of clinically relevant material: metabolism of alcohol, short-term effects of alcohol, long-term effects of alcohol, AUD, alcohol withdrawal, and alcohol use in pregnancy. The KPAAQ was administered to 75 medical students in Years 4 and 5 from the Hebrew University in Jerusalem, Israel, during a relevant clinical rotation. Following the initial administration of the KPAAQ, the students attended a 60-minute lecture (in Hebrew) based on material from the University of Sydney's learning module on alcohol. The KPAAQ was readministered to the students immediately following the lecture. Results: The KPAAQ demonstrated good reliability (Cronbach α =.92 for all questions) and validity r(209) =.674, P <.001. Knowledge of alcohol and alcoholism significantly increased after the educational intervention (F(2, 154) = 151.60, P <.001). Post hoc comparisons using the Scheffe test revealed a significant positive change in knowledge after students received the intervention (mean difference = 33, P <.001). Conclusions: These initial findings suggest that the KPAAQ is a reliable and valid instrument for assessing medical student knowledge of psychiatric aspects of AUD over 6 clinical categories.
