[The reliability and validity of a Drinking Refusal Self-Efficacy Questionnaire-Revised (DRSEQ-R) in Korean college students].
OBJECTIVE
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 emotional 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 component 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.


CONCLUSIONS
Based on the findings, DRSEQ-R is a reliable and valid instrument to measure for drinking refusal self-efficacy in Korean college students.
