Life before and after quitting smoking: an electronic diary study

Area of Science:

• Addiction research
• Behavioral psychology
• Nicotine dependence

Background:

• Nicotine withdrawal is a complex phenomenon impacting smoking cessation.
• Previous research has often used unidimensional assessments of withdrawal symptoms.
• Understanding the temporal dynamics and individual variability of withdrawal is crucial for effective interventions.

Purpose of the Study:

• To describe a multidimensional, multivariate, and multilevel approach to assessing nicotine withdrawal.
• To examine the temporal patterns and individual differences in affective and nonaffective withdrawal symptoms.
• To investigate how withdrawal symptom experiences and their relation to external events change over time and impact smoking cessation outcomes.

Main Methods:

• Prospective study with 70 adult smokers using active or placebo nicotine patches.
• Multiple daily assessments via electronic diary.
• Estimation of average and individual growth curves for withdrawal symptoms.
• Analysis of changes in symptom-event relations from pre-quit to post-quit.

Main Results:

• Most nicotine withdrawal symptoms, excluding hunger, significantly increased on quit day and persisted for three weeks.
• Individual variability in symptom experience heightened post-quit compared to pre-quit.
• The relationship between symptom reports and episodic events (e.g., stress, exposure to smoking cues) shifted after quitting.
• Elevated negative affect pre-quit and craving on quit day were linked to lower abstinence rates at three months.

Conclusions:

• A multidimensional assessment approach reveals complex patterns in nicotine withdrawal.
• Anticipatory and immediate withdrawal reactions are significant predictors of long-term smoking cessation success.
• Tailored interventions addressing specific symptom trajectories and individual variability may improve quit rates.
