Abstract:Objective: This study examines to what extent smoking reduction in COPD patients is achieved through the REDUQ program and how smoking reduction can be explained. Design: Randomized, controlled multicenter trial. Subjects: For the REDUQ study participated 110 COPD patients of Medical Spectrum Twente hospital [MST] and the University Medical Centre Groningen [UMCG]. Of those 110 86 were from the MST and 24 patients from the UMCG. Method: Validity of self-reported measures was analyzed. An Intention-to-treat analysis to compared the reduction of ≥50% between the intensive intervention and the placebo self help intervention after 6 and 12 months. A univariate Analysis of Variance is conducted to determine the effect of successful smoking reduction on stage of change regarding smoking cessation. A hierarchical logistic regression is conducted to determine possible predictive determinants of smoking reduction. Results: The self-reported measures were found to be incongruent. The intention-to-treat analysis showed statistically significant effects for 6 months, but no statistical significance for 12 months. The effect of successful smoking reduction on stage of change regarding smoking cessation was statistically not significant. Determination of possible predictive determinants show that self-efficacy after 6 months increases the chance of smoking reduction. Craving and anxiety regarding to withdrawal after 12 months decreases the chance of smoking reduction after 12 months. Conclusion: Objective measures remain the golden standard. A smoking reduction can be achieved through the REDUQ program after 6 months. Successful smoking reduction does not lead to a progression of stage of change and a prospective determinant for smoking reduction after 6 month is self-efficacy and for smoking reduction after 12 months are craving and anxiety regarding to withdrawal.
