| Abstract: | BackgroundThis 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.MethodsSecondary 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.ResultsSocial 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. R2 = 0.18, p < .001 respectively. The DRSEQ-RA and the DRSEQ-SRA also have excellent scale and subscale internal reliability (αs = 0.92–0.99).ConclusionsThe 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. |
