Implicit attitudes to smoking are associated with craving and dependence

Area of Science:

• Psychology
• Neuroscience
• Addiction Research

Background:

• The Implicit Association Test (IAT) is a tool to measure automatic affective responses to drug cues.
• Understanding these automatic responses is crucial for addiction research and treatment.

Purpose of the Study:

• To investigate how smoking status (abstinence vs. non-abstinence) and recent smoking affect automatic affective responses to smoking cues using the IAT.
• To examine the association between IAT effects and measures of smoking urges and nicotine dependence.

Main Methods:

• Fifty-seven smokers completed the IAT under four conditions: abstinence with no smoking (AB-NS), abstinence with prior smoking (AB-S), non-abstinence with no prior smoking (NON-NS), and non-abstinence with prior smoking (NON-S).
• Repeated measures ANOVA and Generalized Estimating Equations were used to analyze IAT effects, craving ratings (Questionnaire of Smoking Urges-Brief), and nicotine dependence (Fagerstrom Test).

Main Results:

• Participants showed a negative IAT effect, indicating a bias against smoking cues.
• Pre-session abstinence attenuated the negative IAT effect, while smoking intensified it, with the most negative effect in the NON-S condition.
• IAT effects correlated positively with craving and nicotine dependence scores, but not with startle response measures.

Conclusions:

• Automatic affective responses to smoking cues, as assessed by the smoking IAT, are sensitive to recent smoking and abstinence.
• These automatic responses are linked to subjective craving and objective measures of nicotine dependence, highlighting their role in smoking motivation.
