Exploring autism parenting, social support, and stigma in a Reddit community
Background Online communities provide a space for parents of children with autism spectrum disorder to discuss social support needs and experiences. Objective This study examined posts in an online Reddit community about autism ( N = 971; published in October 2024). Method We trained a large language model to code anonymized posts based on the presence of social support types (informational, emotional, network), positive and negative sentiment, a…
Message reactance as a mediator of effects of alcohol and cancer risk messages
This study examined whether message reactance mediates the cognitive effects of messages about the causal relationship between alcohol and cancer. We randomly assigned US adults (N = 799) recruited from a commercial online research panel to receive one of two types of messages about the alcohol-cancer link: (1) high-certainty (e.g., “Drinking alcohol causes cancer”), and (2) low-certainty, employing the modal verb “may” (e.g., “Drinking alcohol m…
Understanding Potential Mechanisms of Vaping Prevention Messages: A Mediation Analysis of the Real Cost Campaign Advertisements
The U.S. Food and Drug Administration (FDA) developed a public education campaign, The Real Cost, that reduced youth susceptibility to tobacco product use. We sought to identify the mechanisms that may underlie the impact of The Real Cost ads on susceptibility to vaping to inform youth tobacco prevention campaigns. Our online randomized controlled trial (clinicaltrials.gov, identifier NCT04836455) examined a large sample of U.S. adolescents ( n =…
Mitigating Health and Science Misinformation: A Scoping Review of Literature from 2017 to 2022
Literature on how to address misinformation has rapidly expanded in recent years. The aim of this scoping review was to synthesize the growing published literature on health and science misinformation mitigation interventions. English-language articles published from January 2017 to July 2022 were included. After title/abstract screening, 115 publications (148 empirical studies) met inclusion criteria and were coded for sample characteristics, to…
Perceptions of HPV-Linked Oropharyngeal Cancer Risk Messages Among a Sample of Young Adult Men in the US: A Pilot Study
Awareness of risk for oropharyngeal cancer from oral human papillomavirus (HPV) infection is low among men in the United States. This pilot study tested messages communicating oral HPV and oropharyngeal cancer risk among a sample of U.S. young adult men (aged 18–26). Six oral HPV and cancer risk messages were tested in an online survey. Participants ( N = 68) were randomly assigned to one of two message sets, each containing three unique text-bas…
Examining the Longitudinal Relationship Between Perceived and Actual Message Effectiveness: A Randomized Trial
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 …
Characteristics of and engagement with URL resources shared among online vaping communities on Reddit
Reddit users in vaping communities share and interact with a variety of external resources. The >200 different vaping-related commerce domains in our sample speak to the breadth and availability of websites that Reddit users (perhaps even those underage) may be using to browse and purchase vaping devices
Adolescents and Young Adults Who Vape or Are Susceptible to Vaping: Characteristics, Product Preferences, and Beliefs
Introduction 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-sect…
Comparison of Message and Effects Perceptions for The Real Cost E-Cigarette Prevention Ads
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 b…
Pictorial Cigarette Pack Warnings Increase Some Risk Appraisals But Not Risk Beliefs: A Meta-Analysis
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 ris…
The Role of Knowledge and Risk Beliefs in Adolescent E-Cigarette Use: A Pilot Study
The use of e-cigarettes and other vaping devices among adolescents is an urgent public health problem due to the concern about adolescent exposure to nicotine. This study examined: (1) adolescents’ knowledge and beliefs about e-cigarette risks; and (2) whether knowledge and risk beliefs were associated with e-cigarette use. N = 69 adolescents completed a cross-sectional survey about e-cigarette knowledge, attitudes (i.e., risk beliefs), and behav…
Who is responsible for Twitter’s echo chamber problem? Evidence from 2016 U.S. election networks
This study examined the echo chamber phenomenon and opinion leadership on Twitter based on the 2016 U.S. presidential election. Network analysis and ‘big data’ analytics were employed to analyze more than 50 million tweets about the two presidential candidates, Donald Trump and Hillary Clinton, during the election cycle. Overall, the results suggested that Twitter communities discussing Trump and Clinton differed significantly in the level of pol…
