Show moreObjectives: Envisioning one's (non)smoking future may make (un)desired future identities more accessible, salient, and personally relevant and facilitate smoking cessation. The current study assessed whether a future-self intervention can weaken smoker self-identity and expected identity loss when quitting smoking, and strengthen quitter-and nonsmoker self-identity, while accounting for personal factors-socioeconomic position, nicotine dependence, consideration of future consequences, and clarity of the envisioned future-self. Additionally, it examined the association between smoking-related identity and quitting intention and behavior. Methods: This longitudinal online experimental study randomized 233 adult smokers to an intervention condition (where they completed mental imagery, visual, and verbal tasks about a future (non)smoking self), or to a passive control condition. Smoker-, quitter-, nonsmoker self-identity and identity loss were measured post-intervention and after one-and three-months. Quit intention and attempts were measured at baseline and after one month. Results: There was a consistent increase in non-smoker self-identity, and decrease in smoker self-identity and identity loss over a period of six months for all participants, but no significant difference in smoking-related identity between the intervention and control group. While personal factors did not moderate the effect of the intervention, we found that smoking-related identity constructs do vary with nicotine dependence, consideration of future consequences, and clarity of the envisioned future-self. Quitting behavior is primarily associated with non-smoker self-identity. Conclusions: Although the future-self intervention did not significantly influence smoking-related identity or behavior, identity-in particular, non-smoker self-identity-is important to consider in smoking cessation in-terventions. More research is needed to find effective operationalizations for identity-based interventions in the context of smoking. Show less

Show moreIdentity, or 'who I am', is important for smoking behaviour. Identity constructs (parts of a person's identity) are typically examined as separate entities, but emerging evidence suggests that the multifaceted nature of identity is relevant in the context of smoking. This cross-sectional study examined how smoking-related self- and group-identity constructs cluster within adult daily smokers (N = 231), whether classes of smokers can be distinguished based on clusters of identity constructs, and which factors explain class membership. Data were collected online in The Netherlands and Belgium, 2017-2018. Latent class and regression tree analyses showed that participants in Class 1 of 'Identified smokers' (estimated population share 54%) reported stronger smoker self- and group-identities, stronger expected identity loss when quitting smoking, and weaker quitter self-identities and non-smoker self- and group-identities (vs. Class 2 of 'Conflicted smokers'). Class membership was explained by the interaction between mental smoking dependence (dominant explanatory variable), consideration of future consequences, age of smoking onset, self-efficacy, and future self thought clarity. Models had good fit. The identity of more dependent smokers is more strongly oriented toward smoking. Smoking is also more strongly embedded in the identity of smokers who started smoking young, are less inclined to think about the future, and have lower self-efficacy. Show less

Show moreThe importance of identity in smoking cessation is increasingly becoming recognized by researchers. This study is the first in-depth longitudinal qualitative investigation of identity change processes among smokers who intend to quit. Participants' accounts of smoking, attempts to quit and sense of identity were explored over time to examine identity continuity and change. Ten smokers with a quit intention were interviewed three times, approximately 1 month apart, and approached for follow-up 2 years later. Data from 30 in-depth interviews were analyzed using the interpretative phenomenological analysis approach. Two themes of identity change processes are presented: "Identity transition makes it easier to quit" and "Identity conflict resolution is needed when quitting is unsuccessful or not attempted." Identity transition toward the identity of nonsmoker appeared to be facilitated by permeable identity boundaries, a continuous sense of identity, and a sense of mastery of quitting. Conflicted smoker identities were observed among participants who continued to smoke, along with barriers that appeared to prevent them from identifying with nonsmoking. Among these participants psychological (e.g. using downward comparisons with worse-off smokers) and behavioral strategies (e.g. hiding smoking from others) were seen that may serve to resolve identity conflict and protect a positive sense of identity. Our findings suggest that transition toward a nonsmoker identity may be necessary for successful quitting. Future research investigating ways to help smokers to perceive themselves increasingly as nonsmokers appears indicated. Show less

Show moreObjective: 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.Methods: In this longitudinal study we examined the reciprocal relations between identity constructs (i.e., smoker self-identity, quitter self-identity and smoker group-identity), intention to quit and smoking and quitting behaviour among a sample of 1036 smokers and ex-smokers, using cross-lagged structural equation modelling. Moreover, we tested whether these relations differed by socio-economic status (SES).Results: Identity and smoking behaviour were reciprocally related in that in intention to quit and smoking behaviour consistently predicted identity change, and identity predicted (changes in) intentions to quit and smoking behaviour. Behaviour appears more important for identity change than identity for behaviour change. Furthermore, quitter self-identity appears more important than smoker self- and group-identity. Relationships did not differ significantly between SES-groups. The findings were replicated using a cross-validation sample.Conclusion: Results imply that changing smoking behaviour may be a vehicle to change smoking-related identity. Moreover, strengthening identification with quitting is more crucial for quit success than decreasing smoker identities. The finding that behaviour may be more important for identity than vice versa, if replicated, may call for additions to identity theories. Show less

Show moreObjectives: Smoking-related self-identity processes are important for smoking cessation. We examined whether quitter self-identity (i.e. identification with quitting smoking) could be strengthened through a writing exercise, and whether expected social support for quitting, manipulated through vignettes, could facilitate identification with quitting. Design: Participants (N = 339 daily smokers) were randomly assigned to a 2 (identity: strengthened quitter self-identity vs. control) × 3 (social support: present vs. absent vs. neutral control) between-participants design. Main Outcome Measures: The main outcome was post-test quitter self-identity. Results: Post-test quitter self-identity was not strengthened successfully. Only a small and marginally significant intervention effect was found on quitter self-identity, which did not generalise to positively influence quit-intention or behaviour. The social support manipulation did not facilitate quitter self-identity. Secondary content analyses showed that quitter self-identity was strengthened among participants who linked quitting smoking to their lifestyle, wanted to become quitters for health reasons, and whose reasons for becoming quitters included approach of positive aspects of quitting, but not among participants who linked quitter self-identity to their self-perceptions. Conclusions: Results provide insight into the content of smokers’ self-conceptualizations as quitters. Writing exercises should be improved and tested to eventually successfully strengthen quitter identities. Show less
