| Abstract: | Even though the combination of face-to-face and online sessions seems a promising new approach in the field of smoking cessation interventions, important information regarding patients' adherence to such interventions, such as the extent to which the patients adhere, how valid is the measurement of adherence and which factors predict adherence, is lacking, while no clear guidelines on how to assess adherence are available. To address this knowledge gap, two separate measures for the evaluation of adherence to a blended smoking cessation treatment offered by Medisch Spectrum Twente and Tactus Addiction Treatment were created, one minutes-based and one features-based measure. Several analyses were performed for the validation of the two measures. In sum, they both exhibited good construct validity (i.e. good convergent and divergent validity), good content validity (i.e. kappa test showed moderate agreement between the two measures) and quite good criterion validity (i.e. good concurrent validity, as the two measures were highly correlated with each other, but poor predictive validity, as adherence did not significantly predict smoking abstinence as expected). Notably, the features-based measure seemed to show better construct and predictive validity and better diagnostic accuracy than the minutes-based measure. Compared to adherence rates reported in previous face-to-face smoking cessation interventions (i.e. 70% adherence on average), a rather low adherence rate of between 20% (using the features-based measure) and 47.1% (using the minutes-based measure) was found. Notably, most non-adherence occurred in the web-based components of this blended intervention. Some possible reasons for that might include characteristics of the technology means used (e.g. low compatibility), of the treatment itself (e.g. too intensive treatment), of the sample investigated (e.g. lower physical or/and mental health than the general population) or/and of the measures used to assess adherence (e.g. too strict measures). The only common predictors of non-adherence between the two measures were health complaints and health and smoking complaints. Taken together, non-adherence was predicted by a lower physical and mental health status (i.e. more health and smoking complaints, more symptoms of anxiety and stress, worse mental health and decreased quality of life), by some cognitive determinants of smoking cessation (i.e. more negative attitude towards smoking cessation and higher social modelling of smoking) and by some demographic variables (i.e. female gender, lower age and absence of a partner). |
