Predictive value of the transtheoretical model to smoking cessation in hospitalized patients with cardiovascular disease.

BackgroundSeveral authors have questioned the transtheoretical model. Determining the predictive value of each cognitive-behavioural element within this model could explain the multiple successes reported in smoking cessation programmes. The purpose of this study was to predict point-prevalent smoking abstinence at 2 and 6 months, using the constructs of the transtheoretical model, when applied to a pooled sample of individuals who were hospitalized for a cardiovascular event.DesignThe study follows a predictive correlation design.MethodsRecently hospitalized patients (n = 168) with cardiovascular disease were pooled from a randomized, controlled trial. Independent variables of the predictive transtheoretical model comprise stages and processes of change, pros and cons to quit smoking (decisional balance), self-efficacy, and social support. These were evaluated at baseline, 2 and 6 months.ResultsCompared to smokers, individuals who abstained from smoking at 2 and 6 months were more confident at baseline t...
