Background: Stigma in people who use drugs predicts treatment engagement, psychosocial health, and overdose, yet there are few evidence-based interventions to support people who use drugs in managing and coping with substance-related stigma and even fewer for people in active use. mHealth is one option to engage this hard-to-reach population.

Methods: Premised on the theory of stigma resistance, this mixed-methods study explored the feasibility, acceptability, and preliminary effectiveness of Project RESTART, a four-week, automated text message intervention for rural-dwelling people who use drugs (n = 30) using a one-group pre-post design.

Introduction: Despite an evolving e-cigarette environment, few studies have looked at adolescent exposure to e-cigarette advertising over time and its associations with curiosity about and susceptibility to using e-cigarettes. We examined e-cigarette advertising exposure and its associations with curiosity and susceptibility across multiple years among adolescents who have never used e-cigarettes.

Methods: We obtained data from the National Youth Tobacco Surveys (NYTSs), 2014-2020 (N = 97,496).

Background: Stigma is a barrier to treatment and harm reduction seeking in people who use drugs. Most stigma reduction interventions offer psychotherapy or psychoeducation in group-based clinical settings, failing to reach people who are not in treatment. SMS text messaging is an effective and acceptable modality for delivering health information to people who use drugs and may be a suitable conduit for providing information and advice to understand and cope with stigma.

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.

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.

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.

Health communication research applies communication science to develop generalizable knowledge capable of improving the health and well-being of individuals and communities. But to what extent does the knowledge generated by the health communication field actually achieve public health impact? To answer this question, we discuss the application of health communication science and research within a tobacco regulatory science framework. We describe three areas in which health communication research funded by the Food and Drug Administration (FDA) Center for Tobacco Products (CTP) contributed to 1) youth tobacco prevention campaigns, 2) cigarette health warnings, and 3) regulation of labeling, advertising, and marketing claims.

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.

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).

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.

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.

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  = 6,622) met inclusion criteria for the meta-analysis.
