Effects of a Social Media Intervention on Vaping Intentions: Randomized Dose-Response Experiment.

Background: e-Cigarette use, especially by young adults, is at unacceptably high levels and represents a public health risk factor. Digital media are increasingly being used to deliver antivaping campaigns, but little is known about their effectiveness or the dose-response effects of content delivery.

Objective: The objectives of this study were to evaluate (1) the effectiveness of a 60-day antivaping social media intervention in changing vaping use intentions and beliefs related to the stimulus content and (2) the dose-response effects of varying levels of exposure to the intervention on vaping outcomes, including anti-industry beliefs, vaping intentions, and other attitudes and beliefs related to vaping.

Evaluation of response to incentive recruitment strategies in a social media-based survey.

Objective: This study aimed to examine varying incentives on acceptance to participate in an online survey on social media and to identify related demographic factors.

Methods: The study used Facebook and targeted its users aged 18 to 24 years in the United States. During recruitment, participants were randomized to one of the three types of incentives for survey completion, (1) a $5 gift card, (2) a lottery for a $200 gift card, and (3) a $5 gift card plus a lottery for a $200 gift card.

Intraoperative techniques to prevent deep incisional or organ-space surgical site infection after emergency surgery for nonappendiceal perforation peritonitis: a prospective two-center observational study.

Purpose: The rate of surgical site infection (SSI) after surgery for secondary peritonitis is very high. This study investigated the relationship between intraoperative procedures of emergency surgery for nonappendiceal perforation peritonitis and deep incisional or organ-space SSI.

Methods: This prospective, two-center observational study included patients aged ≥ 20 years who underwent emergency surgery for perforation peritonitis between April 2017 and March 2020.

Assessing the Feasibility of Studying Awareness of a Digital Health Campaign on Facebook: Pilot Study Comparing Young Adult Subsamples.

Background: Mass media campaigns for preventive health messaging have been shown to be effective through years of research. However, few studies have assessed the effectiveness of campaigns on digital media, which is currently how youths and young adults are primarily consuming media. In particular, a platform that can accurately assess exposure to digital messaging in a real-life setting has yet to be developed.

The Measurement of Dose and Response for Smoking Behavior Change Interventions in the Digital Age: Systematic Review.

Background: There is little consensus regarding effective digital health interventions for diverse populations, which is due in part to the difficulty of quantifying the impact of various media and content and the lack of consensus on evaluating dosage and outcomes. In particular, digital smoking behavior change intervention is an area where consistency of measurement has been a challenge because of emerging products and rapid policy changes. This study reviewed the contents and outcomes of digital smoking interventions and the consistency of reporting to inform future research.
