Aims: This study is aimed at describing the psychometric properties and factor structure of the Swedish version of the Readiness to Change Questionnaire (RTCQ). Originally, the questionnaire included three factors (Precontemplation, Contemplation and Action) in a model that intends to measure stages of change. Methods: Patients at an emergency ward were screened for hazardous alcohol consumption and patients who met risk criteria and responded to the RTCQ were included in the study (n = 165). A confirmatory factor analysis proved to be slightly more suitable for a three-factor solution, compared to the one-factor solution. Results: The three scales reflecting the three factors showed satisfactory reliability. Conclusions: The presented data give no support for abandoning the original use of the test.
