362 Examining Temporal Links Between Distinct Negative Emotions and Tobacco Lapse During A Cessation Attempt

OBJECTIVES/GOALS: Negative emotions (NE) play a pivotal role in addiction-related processes, including tobacco lapse during a quit attempt. Some NEs (e.g., shame, guilt) are posited to lead to a spiraling effect, whereby lapse predicts increased NEs leading to further lapse. This study goal is to examine associations between NEs and lapse. METHODS/STUDY POPULATION: This study examined associations between tobacco lapse and 13 distinct NEs among people who use tobacco and are trying to quit in two tobacco cessation studies. In Study 1, 220 adult (ages 18-74) cigarette users who identified as Black (50% female) participated in a 14-day study where ecological momentary assessment (with assessments approximately every 4 hours) was used to assess emotions and lapse in real-time and real-world settings. In Study 2, 288 adult (ages 18-71) cigarette users who were low socioeconomic status (51% White, 14% Black, 10% Hispanic, 49% female) participated in a 14-day study with the same study protocol as Study 1. Between and lagged within-person associations testing links between distinct NEs and lapse were examined with multilevel modeling with logistic links for binary outcomes. RESULTS/ANTICIPATED RESULTS: Results from Study 1 suggested that at the between-person level, disgust (OR =1.22, CI: 1.05, 1.42), nervousness (OR=1.23, CI:1.05,1.43), guilt (OR=1.40, CI: 1.16,1.69), and sadness (OR=1.18, CI:1.02,1.36) were predictive of higher odds of lapse, and at the within-person level, shame (OR=1.23, CI:1.04,1.45) was associated with higher odds of lapse. Results from Study 2 were similar and suggested that at the between-person level, disgust (OR=1.35, CI: 1.16, 1.56) and guilt (OR=1.88, CI:1.07,3.30), and at the within-person level, shame (OR =1.31, CI:1.10,1.55), were associated with higher odds of lapse. DISCUSSION/SIGNIFICANCE: The present study uses real-time, real-world data to demonstrate the role of distinct NEs on momentary tobacco lapse and helps elucidate specific NE that hinder the ability to abstain from tobacco use during a quit attempt. Results suggest that disgust, guilt, and shame play consistent roles in predicting lapse among diverse samples of tobacco users.
