Background: Cannabis refusal self-efficacy (CRSE), as the people´s belief about their capacity to resist cannabis, has been probed to predict cannabis use and related behaviors. The CRSE Questionnaire (CRSEQ) has 14 items grouped into Emotional Relief Self-Efficacy (6 items), Opportunistic Self-Efficacy (5 items), and Social Facilitation (3 items), forming a CRSE higher-order factor. Objective: To validate the CRSEQ for its use in the Chilean population. Method: The CRSEQ was administered to 1,275 individuals aged 12 to 77 (835 females). Confirmatory Factor Analysis was used to evaluate 14-item and 19-item models. Estimates of internal consistency, temporal stability, and convergent validity with cannabis use behaviors and reward sensitivity were obtained. Additionally, three multigroup invariance tests were conducted. Results: Both models exhibited good fit indices. The 14-item model showed χ2 (74) = 245.662, p
