Implicit attitudes to smoking are associated with craving and dependence

The Implicit Association Test (IAT) has been used to assess automatic affective responses to drug cues. Smokers (n=57) completed the IAT at four experimental sessions. They abstained from smoking before two of the sessions (AB) and smoked normally before the other two sessions (NON). At one AB (and NON) session, they smoked a cigarette about 40 min before completing the IAT (S), and at the other they did not smoke (NS). Overall, participants exhibited a negative IAT effect, indicating that they found the classification task easier when smoking was paired with bad than when smoking was paired with good. Using repeated measures ANOVA, the IAT effect was made less negative by pre-session abstinence, and made more negative by smoking. It was most negative in the NON-S condition. Using Generalized Estimating Equations analyses, the IAT effect was positively associated with pre-task craving ratings assessed on the Questionnaire of Smoking Urges-Brief but was not associated with a physiological measure of automatic affective responses (startles while viewing smoking versus neutral pictures). The IAT effect was associated with scores on the Fagerstrom Test for Nicotine Dependence. In sum, automatic affective responses assessed with the smoking IAT are associated with measures of smoking motivation and dependence. (c) 2007 Elsevier Ireland Ltd. All rights reserved.
