Designing Effective Alcohol Health Warnings: An Experimental Study With Adults in the U.S.

8 settembre 2026 aggiornato da: University of Oklahoma
Consuming alcohol is a dose-dependent and modifiable risk factor for breast cancer. Although alcohol consumption contributes to an estimated 16% of breast cancer cases, awareness of the link between alcohol and breast cancer risk remains low. Systematically developed and tested health warnings can support population-based approaches and intervention strategies to decrease alcohol consumption and breast cancer risk. For instance, the U.S. Food and Drug Administration can mandate specific warnings through statements (e.g., "WARNING: This product contains nicotine…") and color graphics depicting the negative health consequences of products that can harm public health, such as tobacco and alcohol. However, health warning statements and graphics should be assessed among intended audiences before implementation. Research has outlined principles for effective health warning statements. This project will test different health warning statements about the health effects of alcohol.

Descrizione dettagliata

Health warning statements should be assessed for effectiveness among target audiences before implementation as interventions. Research has outlined principles for effective health warning statements. Specifically, health warning statements are effective when they impact mediators of health behavior (e.g., message perceptions, emotional/affective reactions, and resistance to messages) as well as actual behavior. Guided by these assumptions, we will conduct an online randomized clinical trial (RCT) (N=2,000) with US female participants (ages 18 to 65 years) who report consuming alcohol in the past 30 days (i.e., people who currently drink) and young adult female non-drinkers (ages 18-29) to assess how both samples rate different alcohol health warning statements presented in different formats.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: Health warning statement evaluations (bottles)
A randomized clinical trial (RCT) cohort of adult participants (18-65) will complete a computer-based survey-experiment during a single study visit (conducted online). They will review a series of hypothetical alcohol products and rate the images.
Comportamentale: Health warning statement evaluations (bottles)
The experiment will use a 2 (health warning statement: single-theme statement vs. composite paragraph) x 2 (pictogram: present vs. absent) x 2 (format: alcohol container vs. alcohol advertisement) between- and within-subjects design. The between-subject groups are 2 (health warning statement: single-theme vs. composite message) x 2 (pictogram: present vs. absent), and the within-subjects factor is the format of warning presentation (2 alcohol containers vs. 2 alcohol advertisements).
