RESUMEN

Se ha demostrado que las falsedades se propagan más rápido y llegan más lejos que la información correcta, y las investigaciones indican que la información errónea puede tener efectos negativos en el mundo real, como amplificar la controversia sobre las vacunas y diseminar la recomendación de tratamientos oncológicos no comprobados. Por consiguiente, la información errónea sobre la salud en las redes sociales requiere con urgencia una mayor acción de quienes trabajan en la investigación y la práctica de la salud pública. Aquí definimos la “información errónea sobre la salud” como cualquier afirmación relacionada con la salud de un hecho que es falso sobre la base del consenso científico actual. Muchos otros tipos de información plantean un desafío para la comunicación de salud, incluidos los hallazgos contradictorios u opuestos, la evidencia cambiante y la información que suscita un alto grado de incertidumbre; sin embargo, estas cuestiones están fuera del ámbito de este artículo editorial, que se centra en información que es ostensiblemente falsa.

RESUMEN

BACKGROUND: Many pro-smoking videos on YouTube reach view counts in the hundreds of thousands and more. Yet, there is limited information on who is viewing these potentially misleading videos. This study attempts to understand the viewership of online pro-smoking videos to examine if youth at high risk for smoking are more likely to watch these videos. METHODS: We conducted a selective exposure experiment with a national sample of youths (ages 15-21 years; n = 614) to identify characteristics that make individuals more likely to select pro-smoking videos. During a 10-min browsing session, participants were given a set of 16 videos (eight smoking and eight nonsmoking) and were asked to view video(s) of their choice. Exposure to videos was unobtrusively logged. View count was manipulated such that smoking videos had either high or low views. RESULTS: Behavioral data revealed that youth with higher interest in smoking were more likely to select and spend more time watching pro-smoking videos than youth with lower interest in smoking. The view count manipulation did not affect selection patterns. However, exposure to high view count smoking videos was associated with more positive attitudes toward smoking. CONCLUSIONS: The findings of this study call into question the existence and prominence of pro-smoking videos on YouTube and bring to attention the need for regulatory or monitoring efforts of such content. IMPLICATIONS: Given the presence and prevalence of misleading pro-smoking videos online, this is the first study to ask the practical and important question of who is viewing these videos. Using behavioral data, we are able to demonstrate that youth who are high at risk for smoking are more susceptible to select and spend more time viewing pro-smoking videos than youth who are low at risk for smoking. Findings also show that when pro-smoking videos appear to be "popular," they affect attitudes toward smoking. Our findings provide policy implications regarding regulation of smoking promotion videos online.

RESUMEN

OBJECTIVES: Recent research has shown that message congruency is beneficial to recall of pictorial health warning label (PWL) content after initial exposure. Despite less attention to the text warning, smokers exposed to congruent PWLs were more likely to recall the text and the message. This study aimed to replicate these findings and to examine whether congruency also affects recall after multiple exposures over time. METHODS: A total of 320 daily smokers (39.7% female; cigarettes/day: M = 15.31, SD = 7.15) were randomized to one congruent or incongruent PWL and attended 4 laboratory sessions over 10 days. During each session, eye movements were recorded while viewing the PWL and open-ended recall of label content was assessed after exposure. RESULTS: Smokers who were exposed to a congruent PWL were more likely to recall the text (p = .01) and the message (p = .02) and less likely to recall the image (p = .003) of the PWL after initial exposure. By day 4, incongruent PWLs were recalled equally well as congruent PWLs. Independent of condition, image recall was initially high and remained high whereas text and message recall was relatively low initially but increased over time. It was not until day 7 that about 80% of text and message recall was observed. CONCLUSIONS: Even when exposed to the same PWL over time, smokers require multiple exposures to recall the text and the message of a PWL. More research on the effects of congruency in the natural environment, where smokers are exposed to multiple PWLs, is needed. IMPLICATIONS: The findings of this study, and of previous work showing that message congruency in PWLs is beneficial to initial recall of PWL content, could potentially help to address legal challenges regarding the implementation of PWLs in the United States. Factually correct text warnings have been uncontested on US cigarettes packages since 1966. Congruent PWLs simply provide a means to visually support the same information as the existing text using a medium that better garners attention to the health information. Investigating and understanding longer-term effects of congruency are important and can empirically inform future warning label development, both in the United States via the Family Smoking Prevention and Tobacco Control Act, and via other governing bodies.

RESUMEN

OBJECTIVES: The purpose of this project was to explore the extent to which e-cigarette advertisements use youth-appealing content. METHODS: A sample of e-cigarette video ads (N = 154) were coded by 3 independent coders using the content appealing to youth (CAY) index, which measures over 40 youth-appealing features. To calculate a total CAY score for each ad, scores were normalized and summed such that a higher score represented the presence of more youth-appealing elements. RESULTS: All ads included some youth-appealing content, with frequent use of emotional appeals, including happiness (68%), friendship (41%), sex (24%), and success (24%). Over half featured animation. However, product appeals, known to be disliked by youth, were also prevalent. Eighty-seven percent used a direct appeal to e-cigarettes' value over tobacco cigarettes; 66% mentioned product composition; and 40% mentioned health. CONCLUSIONS: Given the unregulated context in the US, e-cigarette marketing currently contains many features that may be particularly appealing to youth.
