A longitudinal study into the reciprocal effects of identities and smoking behaviour: Findings from the ITC Netherlands Survey

OBJECTIVE: Although it has been found that identity constructs related to smoking are associated with changes in smoking behaviour, the direction of causal associations is as yet unclear. This study aims to clarify the nature and direction of these associations.
