Pictorial warnings on cigarette packs motivate smokers to quit, and yet the warnings’ theoretical mechanisms are not clearly understood. To clarify the role that risk appraisals play in pictorial warnings’ impacts, we conducted a meta-analysis of the experimental literature. We meta-analyzed 57 studies, conducted in 13 countries, with a cumulative N of 42,854. Pictorial warnings elicited greater cognitive elaboration (e.g., thinking about the risks of smoking; d = 1.27; p

Gastrointestinal (GI) illness interventions are increasingly utilizing eHealth technologies, yet little is currently known about the extent of their impact on patient outcomes. The purpose of this study was to conduct a meta-analysis of the GI eHealth intervention literature. We used a comprehensive search strategy to locate studies. To be included, studies had to be a randomized controlled trial comparing an eHealth intervention condition against a no-treatment or waitlist control condition. Studies had to report data on at least one of the following patient outcomes: medication adherence, quality of life (QoL), psychological distress, illness-related knowledge, or number of patient visits to the clinic/hospital. Analyses weighted effect sizes (d) by their inverse variance and combined them using random effects meta-analytic procedures. K = 19 studies conducted in eight countries with a cumulative sample size of N = 3,193 were meta-analyzed. Findings indicated that GI eHealth interventions improved patients’ QoL (d = .25, p = .008), psychological distress (d = .24, p = .017), medication adherence (d = .17, p = .014), and illness-related knowledge (d = .19, p = .002). GI eHealth interventions also significantly reduced the number of patient visits to the clinic/hospital (d = .78, p = .005). Our findings suggest that eHealth interventions hold promise in improving patient outcomes for those with GI illnesses. We suggest the next generation of GI interventions continue developing and evaluating the impact of technology using randomized controlled trial designs, and perhaps consider adapting existing efficacious interventions for burgeoning platforms, such as smartphones and tablets.

Following the homicide of George Floyd on May 25, 2020, young adults participated widely in national protests against racism and police brutality. This study examined temporal trends and correlates of self-reported distress about police brutality from May 18 to August 3, 2020 among a cohort of young adults (ages 19–22; N = 2,080) from Los Angeles, CA. Bivariate and adjusted linear regression models estimated the association between survey completion date and distress about police brutality. Distress about police brutality increased substantially in the 2-weeks after Floyd’s death (43% increase over baseline), but gradually declined over the ensuing 8 weeks to a 19% increase over baseline. Results suggest that police violence is contributing to stress and worry among young adults.

This article argues that a set of recent books published in advance of the 2016 U.S. presidential election provides a road map for understanding its outcome and a research agenda for political communication scholars in the years ahead. This article focuses on sociologist Arlie Hochschild’s Strangers in Their Own Land, a field study that documents the roles that identity, narratives, and emotions play in shaping the political beliefs and behavior of White Tea Party supporters. Building on these insights, through an analysis of 123 content analyses published in Political Communication between 2003-2016, we demonstrate gaps in our field and argue that scholarship can grow analytically and empirically by accounting for the findings of these books. We conclude with suggestions for future research into people’s perceptions of identity, group status, deprivation, and political power, as well as the role of media, political actors, and social groups in creating these narratives of American politics.

E-cigarette use in the United States has significantly grown in recent years. Widespread diffusion of e-cigarette content across social media communities may be contributing to this growth. In this study, we (1) explored topics related to e-cigarettes and vaping on Reddit and (2) examined the extent to which these topics clustered across distinct communities. We analyzed a total of N = 79,783 Reddit submissions posted between March 2017 and February 2018 that mentioned at least one e-cigarette or vaping keyword. We created a dictionary to classify submissions into seven different topics related to e-cigarettes and vaping. Submissions were also categorized into one of six mutually exclusive communities identified using subreddit meta-data. Our results indicate that e-cigarette and vaping content on Reddit is primarily about the buying and selling of e-cigarette products. Other common topics included how to build vaping devices, e-juice, and e-cigarette advice. Network correlation analyses found that the distribution of our seven identified topics varied significantly among general e-cigarette, drugs, and research/news subreddit communities. Findings from this study add to a growing literature investigating e-cigarettes and vaping on social media and also contribute to network-level theories by linking communities on Reddit to the diffusion of various depictions of e-cigarettes and vaping.

Target audience ratings of the likely impact of persuasive messages, known as perceived message effectiveness (PME), are commonly used during message development and selection. PME is also used to examine receptivity of messages after they are fully developed or deployed. Despite this, we know little about the conceptual and methodological characteristics of extant PME measures used in the literature. We conducted a systematic review of tobacco education video, print, and audio campaign studies to examine conceptual and methodological characteristics of PME measures. One hundred twenty-six PME measures from 75 studies conducted in 21 countries with more than 61,000 participants were reviewed. Results indicated considerable variability in measures' focus on general perceptions of a message (i.e., message perceptions) versus perceptions of expected message effects (i.e., effects perceptions). Considerable variability was also found on underlying persuasive constructs, use of referents, and referencing of behavior in PME items and measures. We conclude with several recommendations for future research on PME measurement and validation.

Target audience ratings of the likely impact of persuasive messages, known as perceived message effectiveness (PME), are commonly used in health communication campaigns. However, applications of PME rely on a critical assumption – i.e., that PME is a valid indicator of the likely effectiveness of messages. To examine the evidence supporting this assumption, we conducted a systematic review and meta-analysis of longitudinal studies in the tobacco education campaigns literature. Six longitudinal studies examining the predictive validity of PME met inclusion criteria. Results indicated that PME ratings were significantly associated with the majority of outcomes studied. In fact, each of the 6 studies found PME to be associated with at least one outcome, and across the 6 studies, PME was associated with message recall, conversations about ads, beliefs about smoking and quitting smoking, quit intentions, and cessation behavior. Meta-analyses demonstrated that PME predicted quit intentions (r=.256, p

ObjectiveFront-of-package (FOP) marketing strategies of a wide variety of beverages were catalogued to examine the prevalence of each strategy prior to a sweeping Chilean restriction of child-directed marketing aimed at reducing obesity-related disease among Chile’s youth.DesignPhotographs of 1005 beverage packages were quantitatively content-analysed to code whether a variety of child-directed, health-oriented and other marketing strategies (e.g. sales promotions) were present on each product’s FOP. Strategies were then analysed based on beverages’ product category, total sugar, energy and tax status (beverages with added sugars are taxed at different rates).SettingPhotographs were taken in six urban supermarkets in Santiago, Chile, representing five different supermarket chains.ResultsBeverages using child-directed characters or nature/fruit references were higher in total sugar and beverages with child-directed characters or childhood/family references were higher in energy than beverages without these respective strategies. Of the beverages taxed at the highest rate (greatest amount of added sugars), 49 % used nutrition and health appeals and 80 % used nature or fruit appeals. Plain waters and plain milks were less likely than other selected product categories to use health-oriented appeals or multiple FOP strategies in combination.ConclusionsFOP marketing on beverages varied according to the nutritional quality of the product, with heavier use of health-oriented and child-directed strategies in less healthy products. Marketing activities warrant continued observation to evaluate how industry responds to new marketing restrictions as these restrictions are evaluated in the light of existing taxes and other regulatory efforts to improve diets and reduce obesity-related disease.
