Abstract Objectives: Our aim was to identify message characteristics for cigarette pack inserts that aim to help smokers quit.
Methods: US adult smokers from an online consumer panel (N = 665) participated in a discrete choice experiment with a 2x2x2x2x4 within-subjects balanced incomplete block design, manipulating: image (vs no image), text type (testimonial vs informational), cessation resource information (vs none), call to action (vs none), and message topic (well-being, financial benefit, cravings, social support). Participants evaluated 9 choice sets, each with 4 inserts, selecting: (1) the most and least helpful for quitting; and (2) the most and least motivating to quit. Linear models regressed choices on insert characteristics, controlling for sociodemographics and smoking-related variables. We assessed interactions between insert characteristics and smoker attributes (ie, education, quit intention, self-efficacy).
Results: Inserts were most helpful and motivating when they included an image, provided cessation resource information, or referenced well-being and financial benefits. Significant interactions indicated that inserts with cessation resource information were relatively more helpful and motivating among smokers with low self-efficacy, an intention to quit, or lower education.
Conclusion: Cigarette pack inserts with imagery and cessation resource information may be particularly effective in promoting smoking cessation.
