Abstract

Abstract: Background: This study aimed to develop and validate a shortened version of the Drinking Refusal Self-Efficacy Questionnaire-Revised Adolescent version (DRSEQ-RA) using a large sample of adolescents. Methods: Secondary school students ( N = 2609, M = 14.52 years, SD = 0.94) completed the DRSEQ-RA (consisting of subscales: Social Pressure; Opportunistic; Emotional Relief) and the Alcohol Use Disorders Identification Test (AUDIT). These data were analysed using non-parametric item response theory (NIRT) including Mokken scalability coefficients, and confirmatory factor analysis. Results: Social Pressure subscale items were better able to distinguish between adolescents with lower or higher levels of drinking refusal self-efficacy, while the Opportunistic and Emotional Relief subscale items were able to distinguish adolescents with low drinking-refusal self-efficacy. The DRSEQ-RA was reduced from 19-items to a 9-item scale and retained the original three-factor structure. The reduced scale was named the Drinking Refusal Self-Efficacy Questionnaire-Shortened Revised Adolescent version (DRSEQ-SRA). The DRSEQ-RA and the DRSEQ-SRA have almost identical psychometric properties. They both demonstrated good fit to the data, each explained 18% of the variance in alcohol consumption, Adj. R 2 = 0.18, p < .001 respectively. The DRSEQ-RA and the DRSEQ-SRA also have excellent scale and subscale internal reliability ( α s = 0.92–0.99). Conclusions: The DRSEQ-SRA is a short, 9-item, measure of adolescent drinking-refusal self-efficacy which demonstrates both reliability and validity. A significant advantage is brevity. The DRSEQ-SRA may be a valuable tool for identifying risk of adolescent drinking and prevention/treatment planning in settings where survey administration time is critical. Highlights: 19-item DSREQ-RA reduced to 9-item scale with similar psychometric properties. The DRSEQ-RA and DRSEQ-SRA each displayed good reliability and validity. The DRSEQ-RA and DRSEQ-SRA each explained 18% of variance in alcohol consumption. The DRSEQ-SRA may be a valuable tool for identifying risk of adolescent drinking. The DRSEQ-SRA may be a valuable tool for prevention/treatment planning.
