Assessing Smoking Cessation Messages with a Discrete Choice Experiment.

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.
