Abstract:Introduction: Smoking is a habit that causes many health hazards, such as pulmonary diseases. Smoking cessation interventions are very common nowadays. Medisch Spectrum Twente has instated a smoking cessation outpatient clinic. Patients are counseled and assisted in their efforts to quit smoking. The present study aims to describe the population at the outpatient clinic and test several possible predictors of success. Method: At baseline, two questionnaires were administered. The Smoking Related Questionnaire was used to measure smoking related behaviors and demographic data, and Beck’s Depression Inventory measured depression scores. Smoking cessation outcomes were extracted from patient files. No follow-up measure was conducted. Predictors were independently tested using independent samples t-tests. A binary logistic regression analysis was conducted to test significant results simultaneously. Results: Significant results found independently were: the first quartile of age (t(124)=2.248, p=.026), self-efficacy (t(131)=3,455, p=0,001), and depression (t(123)=-3,649, p<0,000). Binary logistic regression analysis using these three predictors proposed an acceptable model (Chi square (3) = 18.05, p<0.001) using these predictors. An R-square of .196 was found. Only depression remained statistically significant in this analysis (OR=1.10, p=.01). DISCUSSION: Depression scores can be used to predict smoking cessation outcomes in this sample, however, the proportion of variance explained is not high, and differences between groups on depression scores were not clinically significant. Lack of follow-up measurements and unstandardized interventions limit the generalizability of this study.
