Predicting changes in smoker identity and quitter identity among smokers and ex-smokers using ITC data

Abstract

Background: Smokers with stronger quitter and non-smoker identities, and weaker smoker identities, are more likely to (intend to) quit smoking. However, little is known about how identity may change in smokers and ex-smokers. We will explore whether changes in identity can be predicted by clusters of variables related to perceived effects of antismoking policies and psychosocial factors. Methods: Longitudinal data (eight waves over eight years) from the International Tobacco Control (ITC) Netherlands survey will be used. Quitter self-identity and smoker self- and group-identity were measured among ± 2000 smokers and ex-smokers. Data will be analysed with cross-lagged structural equation modelling. Expected results: Results will show how antismoking policies and psychosocial factors may affect identity change and behaviour in smokers and ex-smokers. Current stage of work: Data have been collected and will be analysed in the first half of 2015. Discussion: More insight in dynamics of identity change processes related to smoking and smoking cessation over time will address an important gap in the current literature, and will aid the development of effective smoking cessation interventions and antismoking measures.
