The Reliability and Validity of a Drinking Refusal Self-Efficacy Questionnaire-Revised (DRSEQ-R) in Korean College Students

Purpose: This study was to test the reliability and validity of a Drinking Refusal Self-Efficacy Questionnaire-Revised (DRSEQ-R) in Korean college students. Methods: The DRSEQ-R was designed to assess an individual’s belief in their ability to refuse drinking alcohol by Oei et al. (2005) and consisted of three factors (social pressure, opportunity, and emo-tional relief). A methodological study design with an exploratory factor analysis for validity and correlation coefficients for reliability was used. DRSEQ-R was translated into Korean and a translation equivalency was obtained. DRSEQ-R was tested with a sample of 201 college students in Korea. The subjects consisted of 106 males and 95 females. Principal com-ponent factor analysis was used for construct validity and Cronbach’s alpha was used to evaluate for internal consistency of the instrument. Results: The factor analysis showed three factors explaining 66.3 % of total variance and the corresponding factors were emotional relief (48.01%), drinking contextual opportunity (11.18%), and social pressure (7.14%). The internal consistency was acceptable (Cronbach’s alpha=.937). All three factors of DRSEQ-R negatively correlated with alcohol dependency and a heavy drinker showed a lower DRSEQ-R than a moderate drinker. Conclusion: Based on the findings
