BACKGROUND: There are few valid clinical assessment instruments for cannabis. Self-efficacy, or the ability of users to resist temptation, is a central feature of social cognitive theory. This study outlines the development and validation of the cannabis refusal self-efficacy questionnaire (CRSEQ), which measures the situational confidence to refuse cannabis. METHOD: One thousand two hundred and forty-six patients referred for cannabis assessment completed the CRSEQ including measures of cannabis consumption and dependence severity (severity of dependence scale-cannabis, SDS-C). The CRSEQ was subject to independent exploratory (n=621, mean age 26.88, 78.6% male) and confirmatory (n=625, mean age 27.51, 76.8% male) factor analysis. RESULTS: Three factors: Emotional Relief, Opportunistic and Social Facilitation were identified. They provided a good statistical and conceptual fit for the data. Emotional relief cannabis refusal self-efficacy was identified as most predictive of cannabis dependence, after controlling for cannabis consumption. CONCLUSIONS: The CRSEQ is recommended as a psychometrically sound and clinically useful measure for cannabis misuse treatment planning and assessment.
