Abstract |
|---|
Aims: The aims of this study were to investigate the performance of the treatment version of the Readiness to Change Questionnaire (RCQ[TV]) among individuals currently receiving alcohol detoxification and to develop a treatment version of the Treatment Readiness Tool (TReaT[TV]). Methods: A total of 549 patients (86% men) recruited from two detoxification units were interviewed close to treatment intake and followed up 12 months later. Confirmatory factor analyses and logistic regression analyses were conducted. Results: A modified nine-item version of the RCQ[TV] showed a good fit of the model (CFI = 0.95) and internal consistencies ranging between 0.49 and 0.91. Twelve months later, RCQ-Actors had an odds ratio of 1.95 (95% CI: 1.12–3.37) for being abstinent compared to Precontemplators/Contemplators. The development of the TReaT[TV] resulted in 15 items and 5 scales with a CFI of 0.97 and Cronbach's alphas ranging between 0.59 and 0.94. TReaT[TV] Precontemplators/Contemplators were less likely to utilize help than Maintainers (OR = 0.17, 95% CI: 0.06–0.45). Conclusions: The psychometric properties were modest for the modified RCQ[TV] and good for the TReaT[TV]. Readiness to change and readiness to seek help should be assessed separately among treatment seekers.
