A systematic review1 of studies in adult general population samples:

1Vangeli et al., 2011, Addiction, 106, 2110-2121.

Background

• Measures related to cigarette dependence:

quit attempts

• Positive smoker identity has not been explored, but might have an impact on both quit attempts and success.

quit success

It may be an important target for messaging aimed at promoting smoking cessation.

• Variables related to motivation to stop smoking: e.g. health concerns and enjoyment of smoking

• Shifting between different smoker identities during smoking cessation6.

Background• Discrepancies between

behaviour and smoker identity10.

• Making effort to distance themselves from their smoker identity7.

• Those with strong non-smoker identity were more likely to remain abstinent than those with an established smoker identity7-9.

• Established smoker identity associated with smoking escalation in adolescents11.

• Smokers with a smoker identity were less likely to make a quit attempt12.

• Smoker and abstainer self-concept at baseline predicted quit success during smoking cessation treatment13.

Aims

1. What is the proportion of smokers in a nationally representative sample who report a positive smoker identity?2. What socio-demographic, smoking variables and smoking- related attitudes are associated with positive smoker identity?

3. What is the predictive relationship between positive smoker identity for quit attempts and quit success at six months follow-up?

To examine the role positive smoker identity plays in making quit attempts as well as quit success prospectively.

Methods

• Cross sectional monthly survey of a representative sample of smokers (age 16 and over) in England14-15.

• A follow-up six months after the baseline.• Measures used in this study were included June 2010 and

March 2012.

• Representative sample of current cigarette smokers (including hand-rolled cigarettes), who smoke daily or occasionally.

• Provided data for all included variables.

• Demographic characteristics (age, gender, social grade);

• Nicotine dendence: Heaviness of Smoking Index;

• Motivation to Stop Scale;

Measures

• Attitudes to smoking: ‘How do you feel about being a smoker?’ (e.g. ‘I like being a smoker’, ‘I enjoy smoking’, ‘I’m confident I could stop if I tried’, ‘I am worried that smoking is harming my health right now’);

• Recent quit attempts: ‘Have you made a serious attempt to stop smoking in the past 12 months?’

• At 6-month follow up: ‘How long ago did the most recent quit attempt start?’;

• Quit success: A quit attempt has been made during the follow up and still not smoking at follow up.

• 18.3% (95% CI=17.5-19.2) of adult smokers had a positive smoker identity.

*Calculated by using weighted data to match the sample with the 2001 census on age, gender and social grade.

Discussion

• In line with previous work16: the majority of smokers did not like being a smoker.

10Levinson et al., 2007, Nicotine Tob Res, 9, 845-852.; 16Jarvis et al., 2002, BMJ, 324(7337): 608; 17Ritchie et al., 2010, Nicotine Tob Res, 12, 622-629.

Increasing social stigmatization and unacceptability of smoking:

Negative feelings about being a smoker17.

Do not want to identify themselves with the this self-label10.

Page 16: Ildiko Tombor, Lion  S hahab, Jamie Brown, Robert West

16

Discussion

• Having a positive smoker identity was independently associated with being older, male, reporting stronger nicotine dependence, lower motivation to stop smoking, addiction to and enjoyment of smoking and not having made a quit attempt in the past year.

18Jarvis et al., 2003, BMJ, 326(7398): 1061.

Similar to some characteristics of ‘hardcore smokers’18.

Longer smoking history and established nicotine dependence: smoking becomes a firmly entrenched part of identity.

Attempt to reduce their cognitive dissonance.

Discussion

1Vangeli et al., 2011, Addiction, 106, 2110-2121.; 5West, 2006, Oxford: Blackwells; 12van den Putte et al., 2009, Health Psych, 28, 535-544.

• Positive smoker identity was an important barrier over and above other predictors of quit attempt prospectively.

Congruent with the predictions of PRIME theory5 and previous studies of smoker identity12 and self-perceived motivational factors for continuing smoking1:

Page 18: Ildiko Tombor, Lion  S hahab, Jamie Brown, Robert West

18

Discussion

• The association between positive smoker identity and quit success was similar in magnitude and was also in the negative direction, but failed to reach statistical significance.

1Vangeli et al., 2011, Addiction, 106, 2110-2121.; 13Shadel & Mermelstein, 1996, Ann Behav Med, 18, 151-156; 19 Diemert et al., 2013, Am J Public Health, 106, 2110-2121.

• As expected1, 19, lower nicotine dependence was associated with quit success.

Further research is needed to verify whether the lack of significant association holds in different samples13.

Page 19: Ildiko Tombor, Lion  S hahab, Jamie Brown, Robert West

19

• A single ‘yes or no’ question was used as an indication of whether a smoker had a positive smoker identity.

Limitations

• There was a low follow-up rate at six months and the follow-up sample was not selected on the basis of representativeness for the general adult population in England.

• Past quit attempts might be forgotten especially if they were unsuccessful or lasted for a shorter period of time or occurred longer ago.

Page 20: Ildiko Tombor, Lion  S hahab, Jamie Brown, Robert West

20

• Only a minority of smokers in England have a positive smoker identity.

• However, this identity aspect appears to be an important barrier to quitting smoking.
