This study explores how people engage with educational and motivational content on TikTok. We conducted a mixed-methods content analysis of N = 400 health videos from the prosocial EduTok campaign. Two theories guided our analysis of content: the motivational theory of role modeling and the health belief model. Our results revealed that audiences most frequently engaged with educational videos related to diet, exercise, and sexual health. Role model appeals were prominently featured and highly engaged with. However, these videos often framed health promotion through an ideal lens, without including information needed for behavior change attainability. The prevalence of constructs from the health belief model in videos varied. Videos emphasizing prevention, cues to action, and behavior antecedents including perceived benefits and severity attracted more views and engagement than videos that did not include these concepts. We further observed a trend in which content creators used severity in a sensational manner to elicit shock and outrage, which in turn boosted content virality. When included, videos featuring efficacy appeals garnered higher engagement. However, these appeals were less common and had limited reach. Overall, our findings provide implications for using role modeling and theory-driven appeals in social media eHealth communication.

Health professionals increasingly use social media to communicate health information, but it is unknown how visual message presentation on these platforms affects message reception. This study used an experiment to analyse how young adults (n = 839) perceive sexual health messages on Instagram. Participants were exposed to one of four conditions based on visual message presentation. Messages with embedded health content had the highest perceived message effectiveness ratings. Additionally, message sensation value, attitudes and systematic information processing were significant predictors of perceived message effectiveness. Implications for visual message design for electronic health are discussed.

Emergency department (ED)-initiated buprenorphine improves outcomes in patients with opioid use disorder; however, adoption varies widely. To reduce variability, we implemented a nurse-driven triage screening question in the electronic health record to identify patients with opioid use disorder, followed by targeted electronic health record prompts to measure withdrawal and guide next steps in management, including initiation of treatment. Our objective was to assess the impact of screening implementation in 3 urban, academic EDs. We conducted a quasiexperimental study of opioid use disorder-related ED visits using electronic health record data from January 2020 to June 2022. The triage protocol was implemented in 3 EDs between March and July 2021, and 2 other EDs in the health system served as controls. We evaluated changes in treatment measures over time and used a difference-in-differences analysis to compare outcomes in the 3 intervention EDs with those in the 2 controls. There were 2,462 visits in the intervention hospitals (1,258 in the preperiod and 1,204 in the postperiod) and 731 in the control hospitals (459 in the preperiod and 272 in the postperiod). Patient characteristics within the intervention and control EDs were similar across the time periods. Compared with the control hospitals, the triage protocol was associated with a 17% greater increase in withdrawal assessment, using the Clinical Opioid Withdrawal Scale (COWS) (95% CI 7 to 27). Buprenorphine prescriptions at discharge also increased by 5% (95% CI 0% to 10%), and naloxone prescriptions increased by 12% points (95% CI 1% to 22%) in the intervention EDs relative to controls. An ED triage screening and treatment protocol led to increased assessment and treatment of opioid use disorder. Protocols designed to make screening and treatment the default practice have promise in increasing the implementation of evidence-based treatment ED opioid use disorder care.

Using the functional, expressive and aesthetic (FEA) consumer needs model, this research investigated plus-size women’s swimwear needs. Swimming is a popular activity for women, which offers numerous physical and mental health benefits. However, little is known about plus-size women’s design preferences and satisfaction with swimwear. Attributes of swimwear were assessed through a mixed-methods qualitative survey (n = 58) and five follow-up focus groups (n = 18) with plus-size women in the western region of the United States. Participants reported greatest dissatisfaction with the functional and aesthetic attributes of swimwear available. The women in this study suggested incorporating greater bust support, increasing the ease of donning and doffing, and offering a variety of styles with modern aesthetics that visually flatter their figures. Based on the results, design implementation should include functional, expressive and aesthetic needs to develop swimwear that satisfies the plus-size consumer. Industry applications are provided.
