Abstract
While research on youth vaping prevention has begun to grow, little work has examined language choice in vaping prevention messages. This study examined adolescents' responses to vaping prevention statements that varied on three features: behavioral framing, linguistic certainty, and target specification. We conducted a 2 (behavioral framing) by 2 (linguistic certainty) by 2 (target specification) by 3 (risk type) plus control condition between-subjects experiment using a national probability sample. Adolescents (N = 1,603) were randomly assigned to one of 25 conditions in which they viewed a vaping prevention statement (or a control statement about vape litter) followed by measures of perceived message effectiveness (PME), perceived severity and susceptibility of vaping risks, message trustworthiness, message relevance, and intentions to seek more information about vaping risks. Results showed main effects of behavioral framing, such that a declarative frame ("Vaping can … ") led to higher PME, higher perceived severity, and greater information seeking intentions than a contingent frame ("If you vape, it can…"), while an interaction revealed that most declarative frame effects were driven by adolescents who were susceptible to vaping. There were also main effects of linguistic certainty, such that the word "can" ("Vaping can … ") led to higher PME, higher perceived susceptibility and severity, and greater information seeking intentions than the word "could" ("Vaping could … "). No main effect of target specification ("you" vs. "teens") was observed. Overall, findings suggest that vaping prevention messages that communicate greater certainty have greater behavior change potential.

Abstract
Use of e-cigarettes and vapes among adolescents continues to be a major public health concern. Health communication efforts can discourage e-cigarette use among adolescents by influencing beliefs and behavior. However, to do so, studies need to identify the most promising themes and messages based on the latest evidence about the harms of e-cigarettes and vaping. Participants were a nationally representative sample of 1,603 US adolescents aged 13-17 years, recruited in the summer of 2022. Adolescents were randomly assigned to view 7 vaping prevention statements (one from each theme: nicotine addiction, chemical harms, health symptoms, mental health, organ effects, cosmetic effects, and monetary cost) and 1 control statement (vape litter theme) from a pool of 46 statements that were developed through a systematic process. Participants rated each statement on perceived message effectiveness (PME), awareness, and believability. Results of linear mixed models indicated that all vaping prevention themes out-performed control messages on PME, with chemical harms and organ effects having the largest effects, followed by nicotine addiction and then other themes. For most message themes, PME effects were stronger for youth susceptible to vaping compared to non-susceptible youth and users. Both awareness and believability predicted higher levels of PME. In secondary analyses, we found that statements specifying the target ("you") and longer statements were also rated higher on PME. Results suggests that the most potent vaping prevention messages for adolescents are those that focus on vape chemicals and the potential of vaping to damage organs and increase disease risk.

Abstract
Background This study examined adolescent pornography viewing and its' relationship with condom attitudes. Methods Data were from 457 adolescents aged 13-18years old who completed an online survey assessing pornography viewing frequency and condom attitudes. Results Many adolescents in our sample had viewed pornography in the past year (n =188, 41%), with pornography viewing frequency being higher among older adolescents (P =0.02), those who have had sex in the past year (P =0.001), and those who identified as White (P =0.01), LGB+ (P =0.05), and male (P =0.001). Adolescents who viewed pornography more frequently had more negative condom attitudes (r =-0.18, P Conclusions A substantial proportion of adolescents in our sample viewed pornography and those who view more frequently had more negative condom attitudes. Results indicate a need for experimental studies examining this relationship and interventions addressing pornography literacy among adolescents.

Abstract
When celebrities, political figures, influencers, or anyone with a large following publicly disclose an illness or die, the news becomes a de facto public health campaign. Until health communicators began studying such disclosures and the effects of the following waves of media coverage, however, it was not known to what extent these events impacted the public. A growing body of research has empirically documented these events and examined the factors that predict which types of audiences are most affected and why. Beyond motivating research opportunities, celebrity and influencer health disclosures or deaths can impact calls to hotlines, views on health-related websites, discussions of related topics on social media, behavioral changes relevant to the disclosure, increased news coverage of celebrity health research, integration of celebrity health narratives into strategic health campaigns, and even policy changes. We provide an overview of research conducted in this area and detail examples of the impact that celebrity health disclosures and studies about those disclosures have had on public discourse and public health.

Abstract
INTRODUCTION We examined awareness and perceptions of the US Food and Drug Administration (FDA) JUUL marketing denial order (MDO) that occurred in June 2022 among a nationally representative sample of US adolescents. AIMS AND METHODS Data were collected in August 2022 via an online survey (n = 1603). Adolescents were asked whether they had heard about the JUUL MDO, and, if yes, where they heard the news. Those who had heard were asked about the MDO's impact on their harm beliefs about JUUL and vape products in general. We examined correlates of awareness of the MDO and of increased JUUL and vape harm perceptions. RESULTS Twenty-seven percent of adolescents had heard about the MDO. Older adolescents (adjusted odds ratio [aOR] = 1.13) and LGBTQ+ adolescents (aOR = 2.05) had significantly higher odds of having heard the news, while those who identified as Black or African American had significantly lower odds of having heard (aOR = 0.56). Most participants who were aware of the MDO indicated that they had higher harm perceptions about JUUL itself (77.9%) and vapes in general (79.6%). Youths susceptible to vaping and current users were less likely to report increased harm perceptions about JUUL (B = -0.34 and -0.46, respectively) and vapes in general (B = -0.27 and -0.43) compared with youth not susceptible to vaping. CONCLUSIONS The results of this nationally representative survey demonstrate that over one-quarter of US youth heard about the JUUL MDO and the vast majority of those indicated increased harm perceptions about vapes. Large-scale news events about vaping can reach youth audiences and may impact what youth think about the harms of vaping. IMPLICATIONS Analysis of a nationally representative survey of adolescents aged 13-17 revealed that more than 25% had heard about the marketing denial order issued to JUUL Labs by the FDA in June of 2022. We also found that the vast majority of adolescents reported increased JUUL and vape harm perceptions in response to hearing about the MDO. This indicates that news coverage about vaping-including coverage of regulatory actions-can reach and potentially impact adolescents. It is therefore important to monitor news coverage about vaping, how it is framed and discussed across media platforms, and its reach among priority populations.

Abstract
BACKGROUND This study reports on the development of pictorial health warning labels for electronic nicotine delivery system (ENDS) using the Delphi approach with a panel of tobacco control experts. Twenty-four evidence-based ENDS-specific warnings corresponding to three themes (toxicity, health risks and specific harm) were developed and used in the Delphi study. METHODS We conducted a three-round online Delphi study among 60 experts (55% female) between June 2022 and April 2023. We balanced the panel in areas of expertise and positions relevant to ENDS (risks, benefits). In round 1, participants rated the warnings on attention, relevance to evidence and perceived effectiveness (harm perception, motivation to quit) and provided suggestions for improvement. In rounds 2 and 3, participants ranked the revised warnings based on importance in each theme. We assessed levels of agreement between participants using interquartile deviations and medians. RESULTS Warnings in theme 1, toxicity, received the highest ratings for perceived effectiveness on harm perception and encouraging quitting ENDS (p<0.05). Experts recommended using clear and affirmative text paired with emotion-provoking pictures and avoiding the rare side effects of ENDS. Most of the top-ranked warnings were from theme 3, ENDS-specific harm, pertained to lung damage, dual use of ENDS and cigarettes, nicotine addiction among youth, anti-ENDS industry sentiment and toxicity. DISCUSSION This study developed 24 evidence-based ENDS health warning labels using a systematic process that included several rounds of expert panel feedback. These warnings can be used to advance ENDS prevention and tobacco control policies and further target different populations.

Abstract
INTRODUCTION Youth represent a high-priority group for e-cigarette health communication. This study examined youth exposure to the Food and Drug Administration (FDA) e-cigarette warning label over 4 years and its association with change in youth harm perception and intention. AIMS AND METHODS We pooled data from the 2018-2021 National Youth Tobacco Survey (age 10-17; n = 67 159). Participants were divided into four groups: never users (58.5%), susceptible nonusers (16.3%), former users (12.7%), and current users (12.5%). We examined the prevalence, time-trend, correlates, and association of youth exposure to the warning with addictiveness and harm perception, intention to use e-cigarettes, and intention to quit all tobacco products. RESULTS Only 24.5% of youth were exposed to the warning. Exposure increased from 14.9% in 2018 to 30.8% in 2019, then declined to 25.2% in 2021. Hispanic (adjusted odds ratio (aOR) = 0.76 [95% CI = 0.641 to 0.89]) and non-Hispanic black current users (0.53 [0.40 to 0.69]) were less likely to be exposed to the warning than white current users. Youth exposure was positively associated with a higher perception of e-cigarette addictiveness (1.12 [1.04 to 1.19]) and intention to quit all tobacco products (1.28 [1.13 to 1.46]). However, exposure was negatively associated with harm perception (0.91 [0.85 to 0.96]) and the intention to use e-cigarettes among e-cigarette nonusers (2.38 [1.99 to 2.84]). CONCLUSIONS The decline in youth exposure to the warning indicates wear-out effects. Strengthening the label by using compelling designs, adding themes on e-cigarette harm to youth, periodically rotating warning content, and using culturally tailored messaging may improve its impact on youth and address racial/ethnic disparities. IMPLICATIONS The FDA e-cigarette label reached only 24.5% of youth, and exposure to the warning declined to indicate wear-out effects. Exposure was significantly lower among minorities. Exposure was associated with a higher perception of e-cigarette addictiveness and intention to quit all tobacco products. Still, it did not increase harm perception or reduce intention to use e-cigarettes among nonusers. Strengthening the label by using more compelling designs, including diverse themes focusing on e-cigarette harm relevant to youth, and periodically rotating warning content may improve its impact on youth. Continued surveillance of the implementation of e-cigarette policies is needed to ensure that they equally affect youth across racial/ethnic subpopulations.

Abstract
Adolescents and young adults continue to use e-cigarettes, and communication campaigns are needed to decrease use among these populations. We developed and tested a point-of-sale communication campaign focused on e-cigarette chemical exposure. We developed messages based on formative research and tested them (versus text-only messages) in a nationally-representative online survey among adolescents and young adults (16-25) (Phase 1). Based on survey findings, we selected a message focused on nicotine and brain development for the point-of-sale trial (Phase 2). We then conducted a cluster-randomized trial at six gas stations with convenience stores, randomly assigned to the intervention (messages displayed) or no message control condition. We conducted intercept surveys with repeated cross-sectional samples of 50 participants (ages 16-25) per store, at baseline and a four-week follow-up. Phase 1 included 1,636 participants in the online study. Intervention messages were rated as more attention grabbing than plain text messages (p < .05), though were rated similarly on other outcomes. Exposure to intervention messages resulted in larger changes from pre- to posttest for beliefs about addiction and relative harms versus cigarettes (p < .05). Phase 2 included 586 participants in the point-of-sale study. Real-world campaign exposure was low (31.8%), and no differences were found between conditions. E-cigarette prevention messages focused on nicotine's impact on brain development show promise. However, garnering attention for communication campaigns in saturated point-of-sale environments, often dominated by tobacco advertising, is challenging. Future efforts should utilize additional communication channels to directly target adolescents and young adults.

Abstract
PURPOSE Tobacco prevention media campaigns are an important tool to address youth tobacco use. We developed a theory-based perceived message effectiveness (PME) Scale to use when vetting messages for campaigns. METHODS Participants were a national sample of N=623 US adolescents (ages 13-17 years) recruited from a national probability-based panel. In an online experiment, we randomised adolescents to view tobacco prevention ads. All participants viewed an ad on smoking or vaping from the US Food and Drug Administration's The Real Cost campaign and a control video, in a random order. After ad exposure, we assessed PME using nine candidate items and constructs for convergent and criterion validity analyses. We used confirmatory factor analysis and examined information curves to select the scale items. RESULTS A brief PME scale with three items (α=0.95) worked equally well for demographically diverse adolescents with different patterns of tobacco use. The Real Cost ads generated higher PME scores than the control videos for both vaping and smoking (convergent validity; p<0.05). Higher PME scores were associated with greater attention, fear, cognitive elaboration and anticipated social interactions (convergent validity; r=0.31-0.66), as well as more negative attitudes toward and lower susceptibility to vaping and smoking (criterion validity; r=-0.14 to -0.37). A single-item PME measure performed similarly to the three-item version. CONCLUSIONS The University of North Carolina PME Scale for Youth is a reliable and valid measure of the potential effectiveness of vaping and smoking prevention ads. Employing PME scales during message development and selection may help youth tobacco prevention campaigns deploy more effective ads.

Abstract
INTRODUCTION In recent years, vaping prevention campaigns have proliferated in response to a surge of e-cigarette use among adolescents in the USA. To date, the research literature has provided minimal guidance as to what vaping prevention message elements have the greatest potential for discouraging vaping, are ineffective or have unintended negative effects. The purpose of the current study was to identify and test a large set of vaping prevention ads used by federal, state, local and non-governmental agencies, examining how objectively coded message elements of vaping prevention messages might affect youth. METHODS A convenience sample of adolescents (N=1501) completed an online survey with each participant rating seven randomly selected vaping prevention ads from a pool of 220 ads on perceived message effectiveness (PME) and vaping appeal. Ads were coded on 37 objective elements in three message categories: themes, imagery and other features. Analyses examined how objective elements predicted PME. RESULTS Addiction, chemicals, negative health symptoms and effects, and cigarette comparison themes were associated with higher PME, as were graphic images and warning symbols. Industry targeting, environmental impact, flavour themes, images of food and people's faces were associated with lower PME, as were hashtags, statistics and first-person language or the word 'teen'. Most elements were not associated with appeal, but ads with a flavour theme were associated with increased vaping appeal. CONCLUSION Promising vaping prevention messages focus on the adverse consequences of vaping, use negative imagery and avoid speaking for teens using their vernacular or perspective.

Abstract
Vaping prevention messages are widely used to communicate the health harms and addiction risks of vaping and discourage vaping among adolescents and young adults. We conducted a meta-analysis of experimental studies to examine the effects of these messages and to understand their theoretical mechanisms. Systematic, comprehensive searches generated 4,451 references, among which 12 studies (cumulative N = 6,622) met inclusion criteria for the meta-analysis. Across these studies, a total of 35 different vaping-related outcomes were measured, and 14 outcomes assessed in two or more independent samples were meta-analyzed. Results showed that compared to control, exposure to vaping prevention messages led to higher vaping risk perceptions, including harm perceptions (d = 0.30, p < .001), perceived likelihood of harm (d = 0.23, p < .001), perceived relative harm (d = 0.14, p = .036), addiction perceptions (d = 0.39, p < .001), perceived likelihood of addiction (d = 0.22, p < .001), and perceived relative addiction (d = 0.33, p = .015). Also, compared to control, exposure to vaping prevention messages led to more vaping knowledge (d = 0.37, p < .001), lower intentions to vape (d = -0.09, p = .022), and higher perceived message effectiveness (message perceptions; d = 0.57, p < .001; effects perceptions; d = 0.55, p < .001). Findings suggest vaping prevention messages have an impact, yet may operate through different theoretical mechanisms than cigarette pack warnings.

Abstract
We sought to examine the relationship between perceived message effectiveness (PME) and actual message effectiveness (AME) in a 3-week randomized trial of vaping prevention advertisements. Participants were US adolescents (n = 1,514) recruited in 2021. We randomly assigned them to view The Real Cost vaping prevention ads or control videos online. Participants viewed three videos at Visit 1, again at Visits 2 and 3, and completed a survey at each visit that assessed AME (susceptibility to vaping) and two types of PME - effects perceptions (potential for behavioral impact) and message perceptions (potential for message processing). At Visit 4, AME was measured. Compared to control, The Real Cost ads led to improved AME (lower susceptibility to vaping at Visit 4, p < .001). This was anticipated by The Real Cost ads eliciting higher PME ratings (higher effects and message perceptions at Visit 1, both p < .001). Furthermore, PME (both effects and message perceptions) at Visit 1 predicted susceptibility to vaping at Visits 1, 2, 3, and 4 (all p < .001). Finally, effects perceptions fully mediated the impact of The Real Cost ads on susceptibility to vaping (β = -.30; p < .001), while message perceptions only partially mediated the effect (β = -.04; p = .001). Our findings indicate a relationship between PME and AME, especially effects perceptions, and suggest that PME may be useful in message pre-testing to select messages with greater behavior change potential.

Abstract
In his commentary, O'Keefe raises some interesting questions about the meaning of effect sizes in meta-analyses of experiments, focusing on our recent meta-analysis on vaping prevention messages. In this commentary, we respond to O'Keefe's comments and make several points. First, it is not uncommon to include experiments with different control conditions in a meta-analysis. Second, the set of studies in our meta-analysis were relatively homogenous, all being experiments testing messages to discourage vaping among adolescents and young adults. Third, the control conditions in each of the studies in the meta-analysis were appropriate for each given study, and our results show homogenous effects on most outcomes. Fourth, our meta-analysis finds meaningful effects that are timely and will be useful to researchers and practitioners alike. As this literature continues to grow, so too will knowledge about the effects of vaping prevention messages and moderators of those effects.

Abstract
BACKGROUND Electronic cigarettes (e-cigarettes) are being advertised and sold with synthetic nicotine. Little research has examined youth awareness of synthetic nicotine or the impact of synthetic nicotine descriptors on perceptions of e-cigarettes. METHODS Participants were a sample of 1603 US adolescents (aged 13-17 years) from a probability-based panel. The survey assessed knowledge of nicotine source in e-cigarettes (from 'tobacco plants' or 'other sources besides tobacco plants') and awareness of e-cigarettes containing synthetic nicotine. Then, in a between-subjects experiment with a 2×3 factorial design, we manipulated descriptors on e-cigarette products: (1) nicotine label (inclusion of the word 'nicotine': present or absent) and (2) source label (inclusion of a source: 'tobacco-free', 'synthetic' or absent). RESULTS Most youth were either unsure (48.1%) or did not think (20.2%) that nicotine in e-cigarettes comes from tobacco plants; similarly, most were unsure (48.2%) or did not think (8.1%) that nicotine in e-cigarettes comes from other sources. There was low-to-moderate awareness of e-cigarettes containing synthetic nicotine (28.7%), with higher awareness among youth who use e-cigarettes (48.0%). While no main effects were observed, there was a significant three-way interaction between e-cigarette status and the experimental manipulations. The 'tobacco-free nicotine' descriptor increased purchase intentions relative to 'synthetic nicotine' (simple slope: 1.20, 95% CI 0.65 to 1.75) and 'nicotine' (simple slope: 1.20, 95% CI 0.67 to 1.73) for youth who use e-cigarettes. CONCLUSIONS Most US youth do not know or have incorrect beliefs about the sources of nicotine in e-cigarettes and describing synthetic nicotine as 'tobacco-free nicotine' increases purchase intentions among youth who use e-cigarettes.

Abstract
Many adolescents and young adults hold erroneous beliefs that cigarillos and waterpipe tobacco (WT) are safer than cigarettes, contributing to use. Communication campaigns can correct misperceptions and increase risk beliefs. We tested point-of-sale (POS) communication campaigns focused on chemical exposure for cigarillos and WT. We conducted two cluster randomized trials at 20 gas stations with convenience stores (10 stores for cigarillos, 10 for WT) in North Carolina between June and November 2017. Within each trial, stores were randomly assigned to either the intervention (campaign messages displayed) or a no message control condition. We conducted intercept surveys with repeated cross-sectional samples of 50 adolescents and young adults (ages 16-25) per store, at baseline and follow-up. There were 978 participants (mean age = 20.9 years) in the cigarillo trial, and 998 participants (mean age = 21.0 years) in the WT trial. Rates of campaign exposure were low (26% for cigarillos; 24.3% for WT). The cigarillo campaign increased knowledge that ammonia is in cigarillo smoke (p < .01). There were also significant increases in knowledge about ammonia and cyanide in cigarillo smoke and arsenic in WT smoke (p < .05) in the sub-sample who reported exposure to the campaign. No differences were found in outcome expectancies, product attitudes, worry about chemical exposure, or behavioral intentions in either campaign. Garnering attention for communication campaigns in saturated POS environments, often dominated by tobacco advertising, is challenging. Our study demonstrates the feasibility of anti-tobacco campaigns at the POS and points to several lessons learned for future POS campaigns.

Abstract
BACKGROUND To evaluate the potential efficacy of increasing harm and relative addiction beliefs in discouraging e-cigarette use, we examined how adolescents' beliefs about e-cigarettes have changed over 6 years and how the predictive validity of these beliefs has changed over time. METHODS Using data from the 2014-2019 National Youth Tobacco Survey (NYTS) (grades 6-12; N = 117,472), we evaluated the association between adolescents' beliefs about the harm and relative addiction of e-cigarettes and current e-cigarette use, as well as susceptibility to use. Logistic regressions and pairwise contrasts were used to analyze changes in these beliefs and determine how well these beliefs predict ever use, current use, and susceptibility to use over time. RESULTS E-cigarette harm and relative addiction beliefs tended to increase over time. In most years, these beliefs were negatively associated with e-cigarette use, including ever use, current use, and susceptibility to use. Interactions between these beliefs were also observed in some years such that harm belief better predicted use when e-cigarettes were also perceived as more addictive. Survey year also interacted with health harm and relative addiction beliefs such that the predictive validity of these beliefs for e-cigarette use decreased over time. CONCLUSIONS Beliefs about e-cigarette harm and relative addiction have increased over time and predict use of, and susceptibility to, e-cigarettes among US adolescents. However, the predictive validity of these beliefs has decreased over time. Future research should explore the reasons for the decreased predictive validity of health beliefs in e-cigarette use and identify constructs that predict adolescent e-cigarette use over and above general harm and relative addiction beliefs.

Abstract
BACKGROUND The US Food and Drug Administration requires six text-only warnings for cigar products, including cigarillos. Research has demonstrated the superiority of pictorial over text-only cigarette warnings, yet the relative effectiveness of pictorial warnings for cigarillos has not been examined. We examined the impact of pictorial cigarillo warnings compared with text-only warnings. METHODS Data were collected from a nationally representative sample of US young adult (18-29) cigarillo users and susceptible non-users. Participants were randomised to one of three experimental conditions: text-only or one of two pictorial conditions (combined for analyses). For each warning, we assessed negative emotional reactions, cognitive elaboration (ie, thinking about cigarillo risks) and perceived message effectiveness (PME). RESULTS Participants (N=661) were 46.5% female, 64.7% white and 21.9% Hispanic; 34.1% reported past 30-day cigarillo use; 41.4% were lifetime users (excluding past 30-day use); and 24.4% were susceptible non-users. Pictorial warnings elicited more negative emotional reactions and higher PME than text-only warnings (p values<0.01), with interactions showing the largest effects for past 30-day users (emotional reactions: d=0.99, PME: d=0.63). For cognitive elaboration, there was no main effect of warning type, but an interaction revealed effects for past 30-day users (p<0.05, d=0.46). CONCLUSIONS Pictorial cigarillo warnings elicited greater negative emotional reactions and PME compared with text-only warnings. These effects and the effects on cognitive elaboration were strongest for past 30-day users. Our findings extend research on cigarette warnings to cigarillos, demonstrating that pictorial warnings are superior to text-only warnings for cigarillos in eliciting beneficial responses.

Abstract
INTRODUCTION Little research has examined the spillover effects of tobacco communication campaigns, such as how anti-smoking ads affect vaping. AIMS AND METHODS Participants were a national sample of 623 U.S. adolescents (ages 13-17 years) from a probability-based panel. In a between-subjects experiment, we randomly assigned adolescents to view one of four videos online: (1) a smoking prevention video ad from the Food and Drug Administration's (FDA) The Real Cost campaign, (2) a neutral control video about smoking, (3) a vaping prevention video ad from The Real Cost campaign, or (4) a neutral control video about vaping. We present effect sizes as Cohen's d, standardized mean differences, with 95% confidence intervals (CIs). RESULTS Exposure to The Real Cost vaping prevention ads led to more negative attitudes toward vaping compared with control (d = 0.30, 95% CI: 0.07, 0.53), while exposure to The Real Cost smoking prevention ads did not affect smoking-related outcomes compared with control (p-values > .05). Turning to spillover effects, exposure to The Real Cost smoking prevention ads led to less susceptibility to vaping (d = -0.34, 95% CI: -0.56, -0.12), more negative attitudes toward vaping (d = 0.43, 95% CI: 0.20, 0.65) and higher perceived likelihood of harm from vaping (d = 0.26, 95% CI: 0.04, 0.48), compared with control. Exposure to The Real Cost vaping prevention ads did not affect smoking-related outcomes compared with control (p-values > .05). CONCLUSIONS This experiment found evidence of beneficial spillover effects of smoking prevention ads on vaping outcomes and found no detrimental effects of vaping prevention ads on smoking outcomes. IMPLICATIONS Little research has examined the spillover effects of tobacco communication campaigns, such as how anti-smoking ads affect vaping. Using a national sample of 623 U.S. adolescents, we found beneficial evidence of spillover effects of smoking prevention ads on vaping outcomes, which is promising since it suggests that smoking prevention campaigns may have the additional benefit of reducing both smoking and vaping among adolescents. Additionally, we found that vaping prevention campaigns did not elicit unintended consequences on smoking-related outcomes, an important finding given concerns that vaping prevention campaigns could drive youth to increase or switch to using combustible cigarettes instead of vaping.

Abstract
While prior reviews have identified positive effects of social media interventions for health behavior change generally, it is unclear whether these effects persist in traditionally underrepresented populations that are at disproportionate risk of disease. The current meta-analysis examined the effectiveness of social media interventions for health behavior change among populations with health disparities. We analyzed 17 studies with a cumulative N = 3,561. Social media interventions had a significant moderate-sized effect on behavior change among populations with health disparities (d = 0.303, 95% CI: 0.156, 0.460, p < .001), and there was significant heterogeneity across the studies (Q = 64.48, p < .001, I2 = 75.19). Exploratory moderator analyses revealed larger effects in studies with smaller sample size (p < .05) and those using additional intervention channels, including e-mail and telephone (p < .05). Findings suggest that social media interventions may be a promising intervention tool for stimulating behavior change among populations with health disparities, but several gaps remain in the literature. Public health professionals and other health communicators should further explore ways to increase both the reach and impact of social media interventions among populations with health disparities.

Abstract
Integrating the extended parallel process model (EPPM) and the emotional flow hypothesis, we tested the persuasive effect of emotional shifts during exposure to a Know the Truth anti-opioid campaign narrative in a sample of middle-school students (n = 480). Testing two emotional flow sequences (threat to efficacy and efficacy to threat) of the Know the Truth narrative against a static (threat-only) emotional condition, we found that youth exposed to any emotional flow narrative reported higher levels of hope and lower levels of fear than those exposed to a threat-only narrative. We also found that a threat to efficacy narrative elicited higher levels of self-efficacy than an efficacy to threat emotional flow condition, suggesting that the emotional sequence influences self-efficacy, a well-established predictor of health behavior change. We conclude that the traditional threat to efficacy emotional flow may be superior to its inverse (efficacy to threat) when communicating with young people about opioid addiction. Implications for message design are discussed.

Abstract
INTRODUCTION Perceived message effectiveness (PME) is a common metric to understand receptivity to tobacco prevention messages, yet most measures have been developed with adults. We examined adolescents' interpretation of language within candidate items for a new youth-targeted PME measure using cognitive interviewing. We sought to understand the meaning adolescents assigned to our candidate PME items to improve item wording. AIMS AND METHODS Participants were 20 adolescents, ages 13-17 years from the United States. Cognitive interviews used a structured guide to elicit feedback on comprehension, answer retrieval, and language regarding a set of Reasoned Action Approach-based survey items that assessed the PME of smoking and vaping prevention ads. We employed thematic analysis to synthesize findings from the interviews. RESULTS Interviews identified three main issues related to survey items: ambiguity of language, word choice (risk and other terminology), and survey item phrasing. Adolescents preferred direct, definitive language over more ambiguous phrasing which they saw as less serious (eg, "will" instead of "could"). For risk terminology, they preferred terms such as "harmful" and "dangerous" over "risky," which was viewed as easy to discount. The term "negative effects" was interpreted as encompassing a broader set of tobacco harms than "health effects." Adolescents said that the term "vape" was preferable to "e-cigarette," and identified ways to simplify item wording for greater clarity. CONCLUSIONS Tobacco risk terms that appear similar differ in meaning to adolescents, and more direct and unambiguous language is preferred. Our findings informed changes to the PME scale items to improve clarity and reduce measurement error. IMPLICATIONS This study adds to the literature on how adolescents interpret tobacco prevention language. Adolescents may interpret terminology differently than adults, which could lead to ambiguity in meaning and thus measurement error. Through cognitive interviewing, we identified and improved the language in a youth-focused PME measure for tobacco and vaping prevention.

Abstract
Importance Understanding whether prevention advertisements reduce susceptibility to vaping is important owing to concerning levels of adolescent vaping. Objective To examine whether vaping prevention advertisements from the US Food and Drug Administration (FDA) national Real Cost campaign lead to lower susceptibility to vaping among adolescents. Design, Setting, and Participants For this 3-group randomized clinical trial with parallel assignment, participants were US adolescents aged 13 to 17 years who were susceptible to vaping or current e-cigarette users, recruited from online panels. Adolescents were randomized to 1 of 2 Real Cost vaping prevention trial groups (health harms- or addiction-themed advertisements) or to a control group (investigator-created neutral videos about vaping). Adolescents completed 4 weekly online surveys at visits 1 to 4 over a 3-week period. Data were analyzed from December 1, 2021, to August 25, 2022. Interventions Adolescents saw 3 randomly ordered 30-second video advertisements online at each of 3 weekly study visits (visits 1, 2, and 3). Main Outcomes and Measures The primary trial outcome was susceptibility to vaping. Surveys also assessed susceptibility to smoking cigarettes to examine any spillover effects of vaping prevention advertisements on smoking outcomes. Both susceptibility measures had 3 items and ranged from 1 (indicating not susceptible) to 4 (indicating highly susceptible). The primary analyses compared Real Cost groups (combined) with the control group, while exploratory analyses compared the Real Cost groups with each other. Results Participants were 1514 adolescents (1140 [75.3%] boys; mean [SD] age, 15.22 [1.18] years), including 504 randomized to the Real Cost health harms group, 506 randomized to the Real Cost addiction group, and 504 randomized to the control group. Adolescents in the Real Cost groups (combined) had lower susceptibility to vaping at visit 4 than those in the control group (b = -0.21; 95% CI, -0.32 to -0.10). The Real Cost groups did not differ from one another on susceptibility to vaping (visit 4: b = -0.05; 95% CI, -0.17 to 0.07). Adolescents in the Real Cost groups (combined) also had lower susceptibility to smoking cigarettes than those in the control group (b = -0.21; 95% CI, -0.32 to -0.10). For both vaping and smoking, Real Cost groups had less positive attitudes (vaping: b = -0.27; 95% CI, -0.40 to -0.14; smoking: b = -0.23; 95% CI, -0.39 to -0.08) compared with the control group. Conclusions and Relevance These findings suggest that vaping prevention advertisements from the FDA Real Cost campaign led to lower adolescent susceptibility to vaping and had beneficial spillover effects on cigarette smoking outcomes. Tobacco prevention campaigns can help reduce youth tobacco use. Trial Registration ClinicalTrials.gov Identifier: NCT04836455.

Abstract
Web-based resources for tobacco use prevention and control provide valuable tools for cancer education. This study sought to (a) identify existing websites that archive prevention and cessation media content and (b) characterize the content and features of those websites. We used a comprehensive search strategy to identify web-based resources. Websites were included if (1) the content was focused on tobacco; (2) a primary purpose of the website was to house a national or international historical archive of anti- or pro-tobacco media or communication content; and (3) the website was designed for researchers or practitioners. Of the 55 websites initially identified, N = 9 met criteria. All websites contained anti-tobacco media content (100%), although 56% also contained pro-tobacco content. Most websites focused on multiple tobacco products (89%), while 11% focused solely on cigarettes. The most common media content in the archives were print ads (67%), warning labels (56%), and video ads (33%). Most archives contained a search function or content filters (67%). While most websites provided free media content with no restrictions (78%), 22% contained paid or restricted content. Other website material included research reports (89%), newsfeeds (89%), fact sheets (67%), advocacy information (56%), and tools for practitioners (44%). This study provides a systematic summary of web-based tobacco prevention and control resources that archive communication and media content. The identified websites can assist researchers and practitioners in their tobacco control efforts, although additional archives focused specifically on vaping media and communication content are needed as the vaping epidemic among youth continues to intensify.

Abstract
OBJECTIVES This umbrella review aims to summarise the evidence about electronic nicotine delivery systems' (ENDS) risk and safety health profile to inform ENDS health communication strategies. DATA SOURCES AND STUDY SELECTION Six databases were searched for systematic reviews presenting evidence on ENDS-related health effects. Ninety reviews divided into five categories were included: toxicity=20, health effects=40, role in smoking cessation=24, role in transition to combustible cigarettes (CCs)=13 and industry marketing claims=4. DATA EXTRACTION Findings were synthesised in narrative summaries. Meta-analyses were conducted by study type when appropriate. Quality assessment was conducted using the Measurement Tool to Assess Systematic Reviews. The Institute of Medicine's Levels of Evidence Framework was used to classify the evidence into high-level, moderate, limited-suggestive and limited-not-conclusive. DATA SYNTHESIS We found high-level evidence that ENDS exposes users to toxic substances; increases the risk of respiratory disease; leads to nicotine dependence; causes serious injuries due to explosion or poisoning; increases smoking cessation in clinical trials but not in observational studies; increases CC initiation; and exposure to ENDS marketing increases its use/intention to use. Evidence was moderate for ENDS association with mental health and substance use, limited-suggestive for cardiovascular, and limited-not-conclusive for cancer, ear, ocular and oral diseases, and pregnancy outcomes. CONCLUSIONS As evidence is accumulating, ENDS communication can focus on high-level evidence on ENDS association with toxicity, nicotine addiction, respiratory disease, ENDS-specific harm (explosion, poisoning) and anti-ENDS industry sentiment. Direct comparison between the harm of CCs and ENDS should be avoided. PROSPERO REGISTRATION NUMBER CRD42021241630.

Abstract
INTRODUCTION Adolescent vaping remains a problem in the United States, yet little is known about what health warning themes most discourage vaping among adolescents. We sought to identify the most compelling themes for vaping warnings for US adolescents. METHODS Participants were a national probability sample of 623 US adolescents aged 13-17 years, recruited in the summer of 2020. Adolescents were randomized to one of the five warning message themes about the potential health effects of vaping: 1. chemical harms, 2. lung harms, 3. Coronavirus Disease 2019 (COVID-19) harms, 4. nicotine addiction, or 5. control (messages about vape litter). The primary outcome was perceived message effectiveness (PME; 3-item scale). Secondary outcomes were negative affect (fear), attention, anticipated social interactions, and message novelty. RESULTS Adolescents rated the chemical, lung, and COVID-19 harms warning messages higher on PME than nicotine addiction and control (all p < .05), while nicotine addiction was rated higher than control (p < .05). The chemical, lung, and COVID-19 harms warning themes also elicited greater negative affect than nicotine addiction and control (all p < .05). For all other secondary outcomes, the COVID-19 harms warning message theme was rated higher than nicotine addiction and control (all p < .05). CONCLUSION Adolescents perceived warning message themes about lung, chemical and COVID-19 health effects of vaping as more effective than nicotine addiction. To discourage vaping, the FDA and others should communicate to youth about the health effects of vaping beyond nicotine addiction. IMPLICATIONS Adolescents rated warning message themes about the lung, chemical, and COVID-19 health effects of vaping as more effective than nicotine addiction, while nicotine addiction was rated as more effective than control themes about vaping litter. To discourage vaping among adolescents, health messaging should expand message themes to communicate about a broader set of health effects of vaping beyond nicotine addiction.

Abstract
E-cigarette use among youth remains a significant public health concern. In 2018, The Real Cost campaign began disseminating messages about the harms of vaping, primarily using digital media. We sought to determine the prevalence of aided recall of The Real Cost e-cigarette prevention ads and identify potential differences by participant characteristics. Participants were a nationally representative sample of adolescents living in United States (US) households recruited by the National Opinion Research Center (NORC) at the University of Chicago's AmeriSpeak panel in September and October of 2020. A total of 623 adolescents completed the survey. Analyses were weighted to represent the distribution of youth in the US, and effect sizes for individual characteristics were estimated using an adjusted marginalized two-part model. Seventy-one percent of adolescents recalled at least one of the five The Real Cost e-cigarette prevention ads, with individual ad recall ranging from a low of 38.8% (for Magic) to a high of 50.1% (for Narrative). Adjusted estimates of aided recall identified significantly higher recall among Black adolescents and those that used social media at medium or high frequencies (p < 0.05). Results support ongoing efforts by the FDA to reach youth with e-cigarette prevention messages using primarily digital media.

Abstract
In 2006, a 10-year retrospective of successful mass mediated health communication campaigns reviewed the field and highlighted strategies for successful campaigns. In the 15 years since the retrospective, there have been dramatic changes in the media environment and advances in health communication research. In this article, we describe changes in the health communication media landscape and in our understanding of mass mediated health communication campaigns in the 15 years since the retrospective. Although the media environment has shifted, we argue that effective principles of health communication have remained relatively constant. We note significant advances in technology since the previous retrospective that can further advance health communication campaigns, with new technologies offering promise as channels for health communication campaigns as well as for campaign planning. We also recommend that campaign researchers report in detail on their use of theory, audience segmentation, channel selection, and the role of formative research when describing campaign efforts; that communicators continue to develop frameworks that integrate principles of effective campaign design; and that additional research focus on understanding how technology can be effectively incorporated into campaign planning, distribution, and evaluation.

Abstract
This proof-of-concept study aims to evaluate the effect of placing graphic health warning labels (GHWLs) on the ENDS device on users' experience, puffing patterns, harm perception, nicotine exposure, and intention to quit or use in the future. JUUL users (n = 26, age 18-24 years; 69% male; 85% Hispanic) were recruited to complete two 60 minutes ad libitum sessions that differed by GHWL on the device (GHWL vs. no-GHWL control) in an experimental clinical lab study. Compared to the control session, using JUUL with GHWL on the device was significantly associated with reduced positive experiences such as pleasure, product liking, and user satisfaction (p-value < 0.05 for all). Also, after exposure to GHWL, participants were less interested in using the same product again (p-value = 0.007), even if it was the only product available on the market compared to control (p-value = 0.03). Trends toward reduced puffing behavior and nicotine boost were also noted during the GHWL, compared to control sessions. This pilot study shows that placing GHWL on the ENDS device may be an effective and promising strategy to reduce ENDS use among young people.

Abstract
BACKGROUND Mobile health technologies can be useful for providing disease self-management information and support to people with inflammatory bowel disease (IBD). OBJECTIVE The aim of this study was to test a self-management SMS text messaging intervention for people with IBD. Our goal was to examine intervention feasibility, acceptability, and engagement and to preliminarily evaluate improvements in certain self-reported health outcomes among participants. METHODS We developed an SMS text messaging program called Text4IBD. The program sent daily support messages and resources about disease self-management over the course of a 2-week, single-group, pretest-posttest intervention to participants (N=114) diagnosed with IBD. We examined intervention feasibility, acceptability, and engagement through Text4IBD message topic recall and use of resources (ie, visiting supplemental websites recommended by the Text4IBD program). We also assessed pretest-posttest measures of IBD-related distress, self-efficacy, perceived support, use of coping strategies, and medication adherence. Analyses examined participants' evaluations of the intervention and compared pretest-posttest changes in secondary outcomes using paired-samples statistics. RESULTS Approximately all participants who completed the intervention (n=105) were receptive to Text4IBD and viewed the program as feasible and acceptable. In addition, most participants (103/105, 98.1%) recalled at least one of the message topics sent by the program, and 79% (83/105) of them self-reported engaging with at least one of the external self-management resources recommended by the Text4IBD program. Pretest-posttest results showed reduced IBD-related distress (mean 3.33, SD 0.68 vs mean 2.86, SD 0.73; P<.001) and improvements in most other secondary outcomes. CONCLUSIONS Findings from this study highlight the value of SMS text messaging as a useful digital medium for providing support to people with IBD, particularly to those who may struggle with disease-related distress. Text4IBD was highly feasible and acceptable and may help people self-manage their IBD. Future studies should aim to evaluate this program in a randomized controlled trial in clinical settings.

Abstract
OBJECTIVE Tobacco butts are the most littered item worldwide and pose a critical environmental and public health hazard. Given the positive impact of required graphic warnings on smoking, we sought to assess the impact of a policy requiring cigarette pack anti-littering messages on smokers' littering intentions. METHODS We randomly assigned US adult smokers (n = 719) to receive labels on the side of their cigarette packs for three weeks: anti-littering messages or messages about chemicals in cigarette smoke. RESULTS Anti-littering messages elicited higher intentions to refrain from littering in the next month compared to chemical messages (p < .05). Anti-littering messages also led to increased knowledge about cigarette butts being the most common form of litter, the number of conversations about littering, and thinking about the proper disposal of cigarettes (all p < .05). Finally, smoking from packs labeled with anti-littering messages led to fewer weeks littering from car windows compared to packs labeled with chemical messages (p < .05), but did not affect completely refraining from littering cigarette butts. Mediators of the messages' impact on littering intentions were thinking about proper cigarette butt disposal and perceived message effectiveness (both p < .05). CONCLUSIONS Policies requiring anti-littering messages on cigarette packs would raise awareness about the problem of cigarette butt litter and bolster intentions to not litter.

Abstract
Ensuring people have access to their preferred method of contraception can be key for meeting their reproductive goals. A growing number of mHealth interventions show promise for improving access to contraception, but no literature review has identified the effects of mHealth interventions among both adolescents and adults in the United States. The purpose of this systematic review was to describe the format, theoretical basis, and impact of mHealth interventions for contraceptive behavior change (contraceptive initiation and continuation) among people of all ages in the US. A systematic review of the literature was conducted using six electronic databases guided by Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. Data on study design, frequency, duration, mHealth modality, contraceptive method, behavior change theory, and behavioral outcome were extracted to facilitate comparison. Eighteen studies met eligibility criteria. The majority (11; 61%) used SMS (short message service). Twelve studies focused on contraceptive initiation, most (n = 8) of which also measured continued use over time. The remaining six interventions focused on continuation alone, generally through appointment reminders. Very little contraceptive behavior change was identified across studies. Current mHealth interventions may hold promise for some health areas but there is little evidence that they change contraceptive behavior. Future mHealth interventions should focus on assessing person-centered outcomes, including satisfaction, side effects, and reasons for discontinuation, to best support people to use their preferred contraceptive method.

Abstract
AIMS To systematically review the literature on (i) whether and how various risk messages about nicotine vaping products (NVPs) alter harm perception and behavioural intentions of smokers and non-smokers and (ii) how trust in sources of NVP risk communication affects message reception and behavioural intentions. METHODS Seven electronic databases and reference lists of relevant articles were searched for articles published up to April 2020. Experimental and quasi-experimental studies on message effects and cross-sectional studies on source credibility were included. The Newcastle-Ottawa Scale and the Evidence Project Risk of Bias Tool were used to assess the quality of observational and intervention studies, respectively. For each outcome variable, we indicated whether there was an effect (as a 'yes' or 'no') and used effect direction plots to display information on the direction of effects. RESULTS Nicotine addiction messages resulted in greater health and addiction risk perceptions, relative risk messages comparing the health risks of NVPs to cigarette smoking increased the perception that NVPs are less harmful than combustible cigarettes, and a nicotine fact sheet corrected misperceptions of nicotine and NVPs. Smokers' intention to purchase, try or switch to NVPs was higher when exposed to a relative risk message and lower when exposed to nicotine addiction warnings. Trust in NVP risk information from public health agencies was associated with lower odds of; (i) NVP use and (ii) perceiving NVPs as less harmful, whereas those who trusted information from NVP companies were more likely to perceive NVPs as less harmful than combustible cigarettes. CONCLUSIONS Relative risk messages may help improve the accuracy of harm perceptions of nicotine vaping products and increase smokers' intentions to quit smoking and/or to switch to vaping, although the literature is nascent.

Abstract
As youth vaping grows, vaping prevention campaigns are emerging rapidly. Our study systematically examines prevention messages used by public health groups. Nicotine addiction and chemicals were the most common message themes. Most messages included imagery, yet just over half had a message source. Results can guide message testing and highlight messaging gaps.
Introduction Federal, state, local, and non-government officials have developed and implemented a variety of vaping prevention messages to curtail the vaping epidemic among youth in the US. This study sought to collect a comprehensive set of vaping prevention messages and characterize the themes and features of those messages. Methods We used a two-fold search strategy to identify messages, utilizing the existing content database from Vaping Prevention Resource (vapingprevention.org) and supplementing those messages with web searches. Potential messages were included if they were vaping prevention-oriented, appropriate or relevant for youth, and in a static web or print format. Results A total of 220 messages met criteria. Messages were coded on the presence or absence of 37 objective features within five categories: message themes, imagery, text features, message perspective, and other (e.g., source). The most common themes were nicotine addiction (32%), chemicals (30%), health effects (24%), and industry targeting (19%). Eighty-five percent of messages included imagery, with 27% showing a vaping device, 22% showing smoke or vapor, and 21% showing a person’s face. Just over half (56%) included a message source. Conclusions Vaping prevention messages for youth have commonly focused on addiction and health risks of vaping, and they vary on a series of text and image features. Further research is needed to understand the efficacy of messaging approaches in preventing vaping among youth.

Abstract
Adolescents with type 1 diabetes (T1D) face a variety of challenges in disease management, and many struggle to achieve optimal glycemic control. Health communication through didactic messaging about the importance of self-management is a commonly used strategy for this population, but narratives have been underutilized. The purpose of this study was to determine if narratives would provide a better tool to improve disease management for adolescents overcoming T1D-specific issues. Adolescent ages 12-17 (N = 191) were enrolled in an online experiment and viewed sets of narratives or standard of care messages. Outcomes were broken into three categories: message evaluation, specifically perceived message effectiveness (PME), and positive emotional reactions; beliefs such as self-efficacy, outcome expectations, and stress and burnout perceptions, and behaviors including disease management and interpersonal communication. Narratives did not significantly outperform standard of care messages, but both message types scored high on PME and other outcomes. We conclude that both narrative and didactic formats may offer utility for healthcare providers working with adolescents, in that narratives provide stories that may inspire positive emotions while standard of care messages provide the necessary clinical information needed to set goals for self-management.

Abstract
Perceived message effectiveness (PME) is commonly used in health communication research and practice, yet there has been a dearth of studies comparing different operationalizations of the PME construct. In the present study, we compared the two major types of PME - message perceptions and effects perceptions - among N = 557 young adults. Participants were randomized to one of two conditions: 1) The Real Cost e-cigarette prevention ads developed by the Food and Drug Administration (FDA condition) or 2) information-only e-cigarette control ads developed by the Mayo Clinic (control ad condition). Study predictors were message and effects perceptions measures and actual message effectiveness (AME) outcomes were risk beliefs about vaping and intentions to vape. Results showed that both message perceptions (M = 3.82 vs M = 3.29; p < .001) and effects perceptions (M = 4.13 vs M = 3.82; p < .001) were higher in the FDA ad condition compared to control. Risk beliefs about vaping were also higher in the FDA ad condition than control (M = 3.95 vs M = 3.79; p =.022), but we found no differences in participants' intentions to vape, which were low overall (M = 1.59 in FDA vs M = 1.58 in control). In multivariate analyses adjusting for covariates and including both types of PME, only effects perceptions (not message perceptions) were associated with risk beliefs about vaping (b =.37, p < .001) and intentions to vape (b = -.26, p < .001). Our findings advance PME research by demonstrating the differing nature of message and effects perceptions, and suggest that effects perceptions should be utilized during message pretesting.

Abstract
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.

Abstract
Since African Americans are disproportionately affected by HIV/AIDS, interventions that increase correct and consistent condom use are urgently needed. We report baseline acceptability data from a randomized controlled trial (RCT) testing the Tailored Information Program for Safer Sex, a computer-tailored intervention designed to increase correct and consistent condom use among low income, heterosexually active African Americans attending an urban sexually transmitted infection (STI) clinic. We enrolled 274 participants at baseline in an RCT-147 in the intervention group. The intervention had high acceptability, with a mean acceptability of 4.35 on a 5-point scale. We conducted a multiple regression analysis examining demographic, structural, and sexual risk characteristics that revealed only sex to be significantly (p < .01) associated with intervention acceptability. While women were more likely than men to find the intervention acceptable, overall the results indicated broad acceptability of this intervention to the target audience. eHealth interventions are a viable option for HIV prevention among African Americans visiting a publicly-funded STI clinic. We discuss implications of these results for the future application of such programs.

Abstract
Background Social media platforms are popular tools for people with inflammatory bowel disease (IBD) to seek support. In the current study, we sought to examine and characterize IBD and distress discourse on public social media platforms. Our goal was to identify topics associated with these online discussions. Methods We collected public social media posts about IBD and distress from Reddit (N = 40 625) and Twitter (N = 40 306) published between September 2017 and August 2019. We created a term-based dictionary to characterize posts based on 8 different, nonmutually exclusive topics: (1) symptoms, (2) medication, (3) nutrition, (4) procedures, (5) marijuana, (6) stigma, (7) ostomy, and (8) intimacy. We used descriptive statistics to characterize the frequency and order the prevalence of the topics on the 2 platforms, and to assess topic co-occurrences among posts. Results Most Reddit (79%) and Twitter (56%) posts mentioned at least 1 IBD topic. The order of topic prevalence was the same for the 2 platforms. Symptoms was the most mentioned topic (Reddit: 57%, Twitter 36%), followed by medication (Reddit: 30%, Twitter 11%), and nutrition (Reddit: 27%, Twitter 9%). Intimacy was the least mentioned topic (Reddit: 2%, Twitter: <1%). Topic co-occurrences varied by platform. Most Reddit posts (57%) mentioned at least 2 IBD topics, whereas only 27% of tweets mentioned multiple IBD topics. Conclusions This study contributes to a growing literature examining how IBD is discussed on social media-specifically, in distress-related contexts on Reddit and Twitter. These cross-platform findings highlight important areas potentially associated with IBD-related distress, which could help facilitate future support.

Abstract
BACKGROUND Waterpipe tobacco (WT) smoking by young adults remains high and misperceptions are common. Product warnings can increase knowledge of harms and reduce use. The goal of this study was to test warning statements, including the FDA-required nicotine warning (prior to implementation), on young adults' thinking about harms of and discouragement from WT smoking. METHODS We conducted a between-subjects experiment in a nationally representative telephone survey of 1,152 young adults ages 18-29. Participants were randomly assigned to hear one of five warning statements and reported how much, on a 4-point scale, the warning made them think about the harms and discouraged them from WT smoking. RESULTS The sample was 36.8% female, 57.8% white, 20.2% Black, 24.1% Hispanic, with a mean age of 23.2 (SE=0.25). Under half (43.5%) had ever smoked WT. There were significant differences among the statements on both thinking about harms (p<.0001) and discouragement (p<.0001). The FDA-required 'nicotine' warning led to the lowest thinking about harms (M=2.85, SE=0.08) and was the least discouraging (M=2.86, SE=0.08), while the '100 cigarettes' warning resulted in the greatest thinking about harms (M=3.62, SE=0.05) and was the most discouraging (M=3.56, SE=0.06). CONCLUSION The nicotine warning resulted in the lowest levels of thinking about harms and discouragement from WT smoking, suggesting limited impact. However, a warning focused on comparing smoke inhalation from WT smoking to cigarettes seems promising. Warnings should cover a broad range of WT health effects, and possibly comparisons to cigarettes. Findings also have implications for the content of international waterpipe warnings. IMPLICATIONS This study indicates that the nicotine warning is the least effective at making young adults think about the harms of and discouraging waterpipe tobacco smoking. The FDA and other countries should consider requiring warnings to cover a broader range of health harms, misperceptions, and possibly comparisons to cigarettes.

Abstract
INTRODUCTION The Food and Drug Administration (FDA) selected six text-only warnings for cigarillos to be implemented on packaging and advertising. Pictorial warnings are more effective at discouraging cigarette use than text-only warnings, yet no research exists for cigarillos. We sought to understand what types of images might be most effectively paired with the cigarillo text warnings to inform broad principles for developing pictorial warnings, with a focus on young adults, who have the highest rate of cigarillo use. METHODS We conducted five focus groups with a total of N = 30 young adult cigarillo users and susceptible nonusers (53% female, 50% White, and 33% Black). Participants were shown four to eight unique images for each of the six text statements and were asked about visual-verbal congruency, emotional and cognitive reactions, and perceived effectiveness of each image. Sessions were recorded and transcribed; two investigators independently coded transcripts for emergent themes. RESULTS Participants reported images that were graphic or "gross" would best grab attention and discourage use of cigarillos. Participants preferred images that were a direct illustration of the information in the warning text, rather than abstract images that required more cognitive effort to understand. Participants also highlighted that including people in the images, especially youth and young adults making eye contact, helped them relate to the warnings, garner their attention, and positively influence their reactions. CONCLUSIONS We identified several principles to inform the selection of images to pair with the FDA-required cigarillo text statements. These insights may also apply to pictorial warnings for other tobacco products. IMPLICATIONS This focus group study identified principles for selecting images to develop pictorial warnings for the six FDA text-only cigarillo warnings. We found that young adult cigarillo users and susceptible nonusers preferred images that were graphic and gross, believable, congruent to the warning text, and included people. Images that match young adults' visual expectations of a disease and are emotion-provoking may be most effective in pictorial warnings and highlight challenges for developing pictorial warnings for health effects that do not have a visible health consequence.

Abstract
Cigarillo use has increased among adolescents and young adults and has remained high. Public education efforts are needed to communicate with these populations about cigarillo use risks, but little is known about the implications of using the term "cigarillo" in such efforts. The study goal was to assess adolescent and young adult perceptions of the term "cigarillo". We conducted a nationally representative online survey of 3517 adolescents and young adults (ages 13-25). We asked participants "what is a cigarillo?" with several response options. Participants were 49.6% female, 69.8% white, 5.2% reported past 30-day cigarillo use, and 11.6% reported lifetime cigarillo use. The most common response to the question "what is a cigarillo" was "I don't know" (51% of participants), followed by "a thinner and smaller version of a traditional cigar" (30.1% of participants), which was chosen by 19.4% of adolescents and 36.8% of young adults. Among past 30-day cigarillo users, the most common response was "I don't know" (54.9%) followed by "a thinner and smaller version of a traditional cigar" (45.1%). Cigarillo users were more likely to select the "a thinner and smaller version of a traditional cigar" response than nonusers. Findings suggest that many adolescents and young adults have varied understandings of the term "cigarillo". Researchers and practitioners need to ensure that terminology used in health communication campaigns is clearly understood by the target audience to maximize effectiveness.

Abstract
We investigated interpersonal communication generated from a successful sexual health intervention for Black college women attending a Historically Black College/University (HBCU). Guided by the integrative model of behavioral prediction and the theory of gender and power, the intervention combined point-of-access health messages with condom distribution via condom dispensers. Using a mixed-methods approach, we examined communication partners, content, mode, valence, and perceived impact. Data were gathered from surveys (N = 105) and interviews (n = 10) with young adult women at an HBCU campus, conducted three months after the intervention. The findings revealed that 43% of women engaged in interpersonal communication and 21% engaged in online interactions about the dispensers. Friends were the most common conversation partners, and the conversations were mainly about condoms and the dispensers themselves. In general, the discussions were positive, showing support for the dispensers. Regression analyses revealed positive, significant associations between interpersonal communication and two key outcomes: condom acceptability and condom intentions. Overall, this study adds to research linking health communication interventions to interpersonal communication and subsequent attitudes and beliefs. Health communication interventions should actively encourage young Black women to share health-promoting information within their social networks to extend both the reach and impact of those interventions.

Abstract
IMPORTANCE The US Food and Drug Administration (FDA) is required to communicate the risks of tobacco constituents to the public. Few studies have addressed how FDA media campaigns can effectively communicate about cigarette smoke constituents. OBJECTIVE To examine whether messages about cigarette smoke constituents are effective in reducing smoking intentions and behaviors among adults who smoke. DESIGN, SETTING, AND PARTICIPANTS This randomized clinical trial enrolled participants who were aged between 18 and 65 years, were English speakers, were living in the United States, and who smoked at least 100 cigarettes during their lifetime and now smoked every day or some days. Participants received daily messages via email for 15 days. Participants were randomized to 1 of 2 message conditions or a control group and reported their previous-day smoking behaviors daily. Follow-up surveys were conducted on days 16 and 32. Data were collected from June 2017 to April 2018 and analyzed from April to September 2018. INTERVENTIONS The 3 groups were (1) constituent plus engagement messages (eg, "Cigarette smoke contains arsenic. This causes heart damage.") that included the FDA as the source and engagement text (eg, "Within 3 months of quitting, your heart and lungs work better. Ready to be tobacco free? You can quit. For free nicotine replacement, call 1-800-QUIT-NOW"); (2) constituent-only messages that did not list the FDA as the source or include engagement text; and (3) a control condition with messages about littering cigarette butts. MAIN OUTCOMES AND MEASURES The primary outcome was the change in quit intentions (range, 1-4, with higher scores indicating stronger intentions) from pretest to day 16. Secondary outcome measures included daily smoking behaviors and quit attempts. RESULTS A total of 789 participants (mean [SD] age, 43.4 [12.9] years; 483 [61.2%] women; 578 [73.3%] White; 717 [90.9%] non-Hispanic) were included in the study. The mean (SD) quit intention score was 2.5 (0.9) at pretest. Mean (SE) change in quit intention score from pretest to day 16 was 0.19 (0.07) points higher in the constituent plus engagement condition than in the control condition (P = .005) and 0.23 (0.07) points higher in the constituent-only condition compared with the control condition (P = .001). Participant reports of cigarettes smoked, forgone, and butted out were similar across study conditions at baseline and did not differ significantly at days 16 and 32 across study conditions. Viewing more messages was associated with an estimated decrease of 0.15 (SE, 0.01) cigarettes smoked per day per message viewed overall across conditions. CONCLUSIONS AND RELEVANCE To our knowledge, this is the first longitudinal test of cigarette constituent campaign messages in a national sample of adults who currently smoke. Messages about cigarette smoke constituents, with or without engagement text and source information, increased participants' intentions to quit, lending support to FDA efforts to educate consumers about such constituents.

Abstract
This study examined differences among current vapers, those susceptible to vaping, and those non-susceptible to vaping among adolescents and young adults (AYAs) in the U.S. We sought to understand vaping-related characteristics, preferences, and beliefs across these populations to inform prevention efforts. Methods: Participants were N=543 adolescents and N=557 young adults recruited in mid-2019 in the U.S. In two separate cross-sectional surveys, we assessed vaping preferences, tobacco product use, and both health harm and addiction risk beliefs about vaping. We ran separate multivariate logistic regressions to assess differences in risk beliefs across the three distinct e-cigarette groups among AYAs. Results: A majority of AYAs were either current vapers (adolescents: 32%, young adults: 36%) or susceptible to vaping (adolescents: 34%, young adults: 24%). In both samples, pod-based devices were the most common device type used, and fruit and mint/menthol were the most commonly used flavors. In multivariate analyses, adolescent (p<.05) and young adult (p<.05) current vapers both had lower risk beliefs about the health harms of vaping compared to those susceptible to vaping. Susceptible adolescents also had lower health harm risk beliefs compared to those who were non-susceptible (p<.05). Addiction risk beliefs seldom predicted use or susceptibility in multivariate analyses, with only susceptible young adults having lower addiction beliefs than those non-susceptible (p<.05). Conclusion: Results from this study highlight the role of health harm risk beliefs among AYA vapers and those susceptible to vaping. Prevention efforts should examine the most potent ways to communicate vaping health harms to discourage AYA vaping.

Abstract
The COVID-19 pandemic has posed unprecedented challenges for the United States and the world. In this article, we discuss several communication challenges that have arisen during the pandemic, with insights from the fields of health and crisis communication. We focus in particular on the lack of clarity in the US response in terms of both what behaviors we are trying to change and how we are communicating about behavior change. While the mixed messages and contradictions have hampered the US response thus far, it is our hope that we will do better going forward. This will require state and local health departments, public health organizations, and all of us to increasingly apply our field's best practices to help calm fears, change behavior, and ultimately reduce suffering and save lives.

Abstract
Introduction The pace and scale of the COVID-19 pandemic, coupled with ongoing efforts by health agencies to communicate harms, have created a pressing need for data to inform messaging about smoking, vaping, and COVID-19. We examined reactions to COVID-19 and traditional health harms messages discouraging smoking and vaping. Methods Participants were a national convenience sample of 810 US adults recruited online in May 2020. All participated in a smoking message experiment and a vaping message experiment, presented in a random order. In each experiment, participants viewed one message formatted as a Twitter post. The experiments adopted a 3 (traditional health harms of smoking or vaping: three harms, one harm, absent) × 2 (COVID-19 harms: one harm, absent) between-subjects design. Outcomes included perceived message effectiveness (primary) and constructs from the Tobacco Warnings Model (secondary: attention, negative affect, cognitive elaboration, social interactions). Results Smoking messages with traditional or COVID-19 harms elicited higher perceived effectiveness for discouraging smoking than control messages without these harms (all p <0.001). However, including both traditional and COVID-19 harms in smoking messages had no benefit beyond including either alone. Smoking messages affected Tobacco Warnings Model constructs and did not elicit more reactance than control messages. Smoking messages also elicited higher perceived effectiveness for discouraging vaping. Including traditional harms in messages about vaping elicited higher perceived effectiveness for discouraging vaping (p <0.05), but including COVID-19 harms did not. Conclusions Messages linking smoking with COVID-19 may hold promise for discouraging smoking and may have the added benefit of also discouraging vaping.

Abstract
INTRODUCTION The US Food and Drug Administration has increased communication efforts that aim to raise public awareness of the harmful constituents (ie, chemicals) in cigarette smoke. We sought to investigate whether the public's awareness of these chemicals has increased in light of such efforts. METHODS Participants were national probability samples of 11 322 US adults and adolescents recruited in 2014-2015 (wave 1) and 2016-2017 (wave 2). Cross-sectional telephone surveys assessed awareness of 24 cigarette smoke chemicals at both timepoints. RESULTS The proportion of US adults aware of cigarette smoke chemicals did not differ between waves 1 and 2 (25% and 26%, p = .19). In contrast, awareness of chemicals among adolescents fell from 28% to 22% (p < .001), mostly due to lower awareness of carbon monoxide, arsenic, benzene, and four other chemicals. Belief that most of the harmful chemicals in cigarette smoke come from burning the cigarette also fell from waves 1 to 2 (adults: 31% vs. 26%; adolescents: 47% vs. 41%, both ps < .05). Participants were more likely to be aware of cigarette smoke chemicals if they had been exposed to anti-smoking campaign advertisements (p < .05) or had previously sought chemical information (p < .05). Cigarette smoke chemical awareness did not differ between smokers and nonsmokers. CONCLUSION Awareness of cigarette smoke chemicals remains low and unchanged among adults and decreased somewhat among adolescents. The association of chemical awareness with information exposure via campaigns and information seeking behavior is promising. More concerted communication efforts may be needed to increase public awareness of cigarette smoke chemicals, which could potentially discourage smoking. IMPLICATIONS Awareness of the toxic chemicals in cigarette smoke may contribute to quitting. The US Food and Drug Administration is making efforts to increase public awareness of these chemicals. Two national surveys (2014-2017) found that chemical awareness was low among adults and adolescents. Although awareness did not change among adults, awareness among adolescents dropped over time. In addition, exposure to anti-smoking campaigns and chemical information seeking behavior were associated with higher awareness of chemicals in cigarette smoke. Campaigns and other efforts may be needed to increase awareness of cigarette smoke chemicals.

Abstract
BACKGROUND The efficacy of e-cigarette prevention ads among adolescents has seldom been studied. We examined the impact of ads from the The Real Cost vaping prevention media campaign on what adolescents think and believe about vaping. We also sought to test whether perceived message effectiveness (PME) served as a proxy for ad impact. METHODS Participants were 543 U.S. adolescents ages 13-17. In an online experiment, we randomized participants to either: 1) persuasive e-cigarette prevention video ads from the Food and Drug Administration's The Real Cost campaign that was targeted to adolescents or 2) information-only e-cigarette harms control videos (control condition). Participants in each condition viewed 2 videos in a random order. After ad exposure, the survey assessed PME (message and effects perceptions), risk beliefs about vaping, attitudes toward vaping, and intentions to vape. RESULTS The FDA's The Real Cost ads led to higher beliefs about the harms of vaping (p < .001), more negative attitudes toward vaping (p < .001), and lower intentions to vape (p < .05) compared to the control videos. The Real Cost ads also scored higher on both message perceptions (p < .001) and effects perceptions (p < .001) compared to control videos. Effects perceptions were associated with all three outcomes (all ps < 0.001, adjusting for both types of PME and covariates), but message perceptions did not offer additional predictive value. CONCLUSIONS Exposure to The Real Cost vaping prevention ads gave adolescents a more negative view of vaping and lowered their intentions to vape compared to control videos. Effects perceptions may be superior to message perceptions as a proxy for e-cigarette prevention ad impact.

Abstract
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 < .001) than text-only warnings. Pictorial warnings also elicited more fear and other negative affect (d = .60; p < .001). In contrast, pictorial warnings had no impact on perceived likelihood of harm (d = .03; p = .064), perceived severity (d = .16; p = .244), or experiential risk (d = .06; p = .449). Thus, while pictorial warnings increase affective and some cognitive risk appraisals, they do not increase beliefs about disease risk. We discuss the role of negative affect in warning effectiveness and the implications for image selection and warning implementation.
