Impact of text-only versus large text-and-picture alcohol warning formats: A functional magnetic resonance imaging study in French young male drinkers.

BACKGROUND: Although the World Health Organization recommends visible and clear warning labels about the risks of alcohol consumption on containers and advertising, many of the currently used labels are too small to be visible. This study investigated the brain activity (using fMRI) and alcohol consumption intentions of French young men exposed to two warning formats displayed on alcoholic beverage advertisements: a small Text-only Alcohol Warning (TAW) currently used in many countries, and a larger text-and-picture alcohol warning (PAW). METHODS: Seventy-four eligible 18-25-year-old male drinkers completed a face-to-face individual visit with a physician expert in addiction medicine. This was followed by the fMRI session during which they viewed 288 stimuli [96 alcohol advertisements with TAWs, the same 96 advertisements with PAWs, and 96 water advertisements (controls)] for 3 s each. If the advertisement made participants want ("yes")/do not want ("no") to consume the product, they pressed the corresponding button (self-report responses). The number of "yes" responses was compared between advertisement types with a paired sample t-test. Whole-brain and region-of-interest (ROI) analyses of the fMRI data were performed. RESULTS: Whole-brain BOLD fMRI highlighted contrasting effects of PAWs and TAWs. Compared with TAWs, PAWs elicited more activation in the precuneus, angular gyrus, occipital, frontal and temporal areas, and less activation in the nucleus accumbens, ventral tegmental areas, and putamen areas (regions of the reward circuit). The ROI analysis confirmed less activation in the reward circuit (left and right ventral tegmental areas, left and right nucleus accumbens) when viewing PAWs than TAWs. Analysis of the self-report responses indicated that the desire to consume the advertised alcohol product was lower when PAWs were viewed (compared with TAWs) (T = 8.18, p < 10-11). CONCLUSIONS: This is the first fMRI study to assess the effect of different alcohol warning formats. Our findings show that compared with TAWs, stronger PAWs in advertisements elicited less activity in key regions of the reward system. This suggests that the effects may influence the desire to consume alcohol products (self-report response analysis). These results could help policymakers who are interested in developing more effective labeling measures that target young people.

Youth behavioural responses to regulated alcohol advertising content: Results from a mixed-methods study in France.

OBJECTIVES: The World Health Organization advocates measures regulating alcohol advertising content, as illustrated by the French Évin law. However, how people react to such regulation has been under-investigated. The research reported here has two objectives: to analyze how different advertising contents (regulated or not) affect the persuasion process from attention to behavioural responses, and whether young people are protected; to examine how alcohol warnings perform depending on their salience and the advertising content displayed (regulated or not). MATERIALS AND METHODS: This study surveyed French people aged 15-30 using a mixed-methods design. In-depth interviews were conducted on 26 respondents to understand how non-regulated (NRA) and regulated (RA) alcohol advertising influence the persuasion process. An experiment on 696 people assessed the influence of RA vs. NRA on intentions to buy and drink alcohol, and whether less vs. more salient warnings displayed in the RA or NRA setting have differential effects on behavioural responses. RESULTS: NRA (vs. RA) had a greater influence on young people's desire to buy and drink alcohol, which we explain by different psychological processes. NRA appeared to trigger a heuristic process that involves affective reactions (e.g. image, symbolism) and product-oriented responses (e.g. quality), whereas RA appeared to trigger a more systematic process that had less influence. The protective effect of content regulations was strong for the youngest participants but fades as age increases, reaching its limits at age 22 years. Salience of the warnings had no influence on desire to buy and drink alcohol, whatever the ad content. CONCLUSION: Advertising content regulations need to be implemented to protect young people, particularly the youngest. Our results on alcohol health warnings highlighted that text-only labels similar to those adopted in many countries are ineffective at decreasing young people's intentions to buy and drink alcohol.

The effectiveness of current French health warnings displayed on alcohol advertisements and alcoholic beverages.

Background: Many countries use health warnings in an attempt to regulate alcohol consumption. However, there is a lack of conclusive evidence in the research on alcohol warnings to support decision-making on effective health policies. This study explores the effectiveness of two mandatory warnings introduced in France in 1991 and 2007: the first (Alcohol abuse is harmful) is displayed on alcohol advertisements; the second (a pictogram) on bottles. Given that advertising content regulations have been implemented in some countries to reduce the attractiveness of alcohol marketing (e.g. the Evin law in France), this research also aims to explore whether such regulations can improve the effectiveness of warnings. Methods: In-depth interviews were conducted with 26 French people aged 15-29 years. The effectiveness of health warnings was assessed in terms of recall, noticeability, credibility, comprehension, responsiveness, and ability to encourage moderate drinking and abstinence during pregnancy. Participants were shown alcohol advertisements and bottles that either followed or challenged content regulations. The data were analyzed using double manual coding and NVivo software. Results: While both warnings suffered from a lack of visibility and noticeability due to their size, location, and outdatedness and because of competition from marketing design elements, the warning on the advertisement that followed content regulations was most visible. Both warnings were considered to be informationally vague, lacking in credibility and ineffective in terms of making participants feel concerned and influencing consumption habits. Conclusions: Current French warnings are ineffective and require modification. Improvements are suggested regarding the design and content of warnings to help increase their effectiveness.
