Introduction: Mood-tailored communications may help increase the effectiveness of smoking cessation messaging interventions. We used both self-report and psychophysiological measures to test the impact of mood on responses to cessation messages in adults who smoke., Methods: In a two-part (crowdsourcing and psychophysiological studies) study, the impact of 30 smoking cessation messages comprised of five themes (i.e., financial, health, quality-of-life, challenges in quitting, motivation to quit) were tested. In a crowdsourcing study, participants (N = 600) were randomly placed into one of three mood induction tasks (i.e., positive, negative, neutral), and then viewed the smoking cessation messages. After each message, they were asked to self-report their motivation to quit, message receptivity, and the perceived relevance of the messages. In an in-lab, psychophysiological study, participants (N = 42) completed the same tasks as the crowdsourcing participants but were monitored for heart rate, skin conductance, and eye-tracking while viewing the cessation messages. Using a multi-attribute decision-making model (MADM) using outcomes from both studies, messages were ranked for each mood state., Results: The top messages for participants in the positive mood condition included the challenges in quitting, financial costs/rewards, and motivations to quit themes. The top messages for participants assigned to the negative mood condition included the challenges in quitting, quality-of-life, and financial costs/rewards themes. For participants in the neutral mood condition, messages in the challenges in quitting and quality of life themes performed best., Conclusions: Variations in the preferences of messages and themes by mood condition suggest that mood-tailored communication may increase the effectiveness of smoking cessation messages., (© 2024.

Objective: Digital interventions have been widely implemented to promote tobacco cessation. However, implementations of these interventions have not yet considered how participants' e-cigarette use may influence their quitting outcomes. We explored the association of e-cigarette use and quitting smoking within the context of a study testing a digital tobacco cessation intervention among individuals in the United States who were 18 years and older, smoked combustible cigarettes, and enrolled in the intervention between August 2017 and March 2019., Results: We identified four e-cigarette user groups (n = 990) based on the participants' baseline and six-month e-cigarette use (non-users, n = 621; recently started users, n = 60; sustained users, n = 187; recently stopped users, n = 122). A multiple logistic regression was used to estimate the adjusted odds ratios (AOR) of six-month quit outcome and the e-cigarette user groups. Compared to e-cigarette non-users, the odds of quitting smoking were significantly higher among recently stopped users (AOR = 1.68, 95% CI [1.06, 2.67], p = 0.03). Participants who were most successful at quitting combustible cigarettes also stopped using e-cigarettes at follow-up, although many sustained using both products. Findings suggest that digital tobacco cessation interventions may carefully consider how to promote e-cigarette use cessation among participants who successfully quit smoking., Trial Registration: ClinicalTrials.gov identifier NCT03224520 (July 21, 2017)., (© 2024.

Background: In the U.S., 9.3% of young adults currently vape. However, little is known about how vaping identity (i.e., internalizing vaping as an important part of oneself) can influence young adults' e-cigarette perceptions. The purpose of this study was to examine the association between vaping identity and e-cigarette perceptions among young adults. Methods: Young adults who vape (N = 252, Mage = 24.7) were recruited to participate in an online survey assessing a trusted source of health information, e-cigarette harm perceptions, and intentions to abstain from vaping. We estimated associations between vaping identity on outcomes and the interaction of vaping identity and combustible cigarette use on outcomes. Results: Participants with higher vaping identity reported lower trust in government health agencies and a doctor, and higher trust in the tobacco industry and e-cigarette industry (ps < 0.05). Those with higher vaping identity also reported lower e-cigarette harm perceptions and intentions to abstain from vaping (ps < 0.05). Conclusions: Findings show that higher vaping identity is associated with greater trust in the tobacco industry, lower trust in health experts, lower e-cigarette harm perceptions, and lower intentions to abstain from using e-cigarettes. This suggests that efforts to reduce vaping among young adults may need to leverage messages that reduce the credibility of the tobacco industry and prevent nonsmoking young adults from developing a vaping identity.
