Abstract:INTRODUCTION- Over the last decades different predictive models of health orientated behavior have been developed and applied to different subjects, including smoking. In this study an elaborated Attitude, Self-efficacy, Social Influence Model (ASE- Model) is combined with an elaborated Transtheoretical Model (TTM). Both are implemented in the patients of a Dutch smoking cessation clinic. SCOPE- The effects of motivational determinants known from the ASE Model on the patients’ intention to quit smoking are evaluated. The TTM divides the intention to cease smoking in two categories (Stages of Change). The ASE model assumes that the motivational determinants act as moderators, when controlled by the characteristic baseline variables of the sample. This assumption is tested. Further, the study aims to evaluate the effect of characteristic baseline variables on the motivational determinates. METHODES - Information is assessed by three measurements: 1) The ‘Smoking related questionnaire´ by Mudde et al., (2000) 2) Beck´s Depression Inventory´ by Beck et al., (1961) 3) Wisconsin Smoking Withdrawal Scale (WSWS)` by Baker at al. (1999). All subsequent statistical analyses are based on a significant bivariate correlation. Binary logistic regression analysis is applied to measure the moderating effect of the ASE Model on the ‘Stages of Change’. Linear regression analysis is assessed to measure the effect of the baseline variables on the motivational determinants. Differences in the groups` mean level of the motivational determinants and ‘Stages of Change’, controlled by the different baseline variables, are calculated by an analysis of variance. RESULTS- The statistical analyses demonstrate that the ASE Model cannot be applied as originally assumed. ‘Self- Efficacy’ is the only motivational determinant that can be used as a slight predictor for the patients’ ‘Stages of Change’. It has no moderating effects. Further, ‘Educational Level’ has a predictive value on the ‘Stages of Change’. The linear analysis demonstrated that 19 % of the variance in the ‘Self- Efficacy’ scores can be explained by three baseline variables. CONCLUSION-The missing results of the ASE Model and the fact that only 82% of the patients in the smoking cessation clinic can be accounted as ‘Preperators’ put the categorization system of the TTM into question. The categorization system might decrease the validity of the study. RECOMMENDATIONS- For further research on this subject different measurement characteristics of the dependent variables are recommended.
