Comparison of five measures of motivation to cult smoking among a sample of hospitalized smokers

OBJECTIVE: To compare the predictive validity of several measures of motivation to quit smoking among inpatients enrolled in a smoking cessation program. METHODS: Data collected during face-to-face counseling sessions included a standard measure of motivation to quit (stage of readiness [Stage]: precontemplation, contemplation, or preparation) and four items with responses grouped in three categories: How much do you want to quit smoking (Want), How likely is it that you will stay off cigarettes after you leave the hospital (Likely), Rate your confidence on a scale from 0 to 100 about successfully quitting In the next month (Confidence), and a counselor assessment in response to the question, How motivated is this patient to quit? (Motivation). patients were classified as nonsmokers if they reported not smoking at both the B-month and 12 month interviews, All patients lost to follow-up were considered smokers, MAIN RESULTS:At 1 year, the smoking cessation rare: was 22.5%. Each measure of motivation to quit was independently associated with cessation (p < .001) when added individually to an adjusted model. Likely was most: closely associated with cessation and Stage was least. Likely had a sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratio of 70.2%, 68.1%. 39.3%, 88.6%, and 2.2, respectively. CONCLUSIONS: The motivation of inpatient smokers to quilt may be as easily and as accurately predicted with a single question as with the series of questions that are typically used.
