Amid the COVID-19 pandemic, TikTok, an emerging social media platform, has created an information hub to provide users with engaging and authoritative COVID-19 information. This study investigates the video format, type and content of the COVID-19 TikTok videos, and how those video attributes are related to quantitative indicators of user engagement, including numbers of views, likes, comments and shares. A content analysis examined 331 videos from official accounts featured in the COVID-19 information hub. As of 5 May 2020, the videos received 907 930 000 views, 29 640 000 likes, 168 880 comments and 781 862 shares. About one in three videos had subtitles, which were positively related to the number of shares. Almost every video included a hashtag, and a higher number of hashtags was related to more likes. Video types included acting, animated infographic, documentary, news, oral speech, pictorial slideshow and TikTok dance. Dance videos had the most shares. Video themes included anti-stigma/anti-rumor, disease knowledge, encouragement, personal precautions, recognition, societal crisis management and work report. Videos conveying alarm/concern emotions, COVID-19 susceptibility and severity, precaution response efficacy had higher user engagement. Public health agencies should be aware of the opportunity of TikTok in health communication and create audience-centered risk communication to engage and inform community members.

The physician-patient relationship in China is highly strained. This study examined the professional identity of physicians and their perceptions of the physician-patient relationship against the backdrop of the rise of health consumerism in China. Structured interviews with 29 physicians found that the marketization of medical care and the rise of health consumerism caused physicians to have a conflicted professional identity. The traditional bureaucratic relationship between physicians and patients based on implicit trust was gradually replaced by an arm's length relationship characterized by self-interest, opportunism, and mistrust. In addition, the transition from physician-centered communication to patient-centered communication in China was tenacious. Theoretical and practical implications of the current study are discussed.

The present research extends the Theory of Planned Behavior (TPB) to investigate how communication-related variables influence condom use intention and behavior among African American women. According to the TPB, attitudes, subjective norms, and self-efficacy are associated with behavioral intent, which predicts behavior. For women, it was argued that condom negotiation self-efficacy was more important than condom use self-efficacy in predicting consistent condom use. Moreover, an important environmental factor that affects condom use for African American women is fear or worry when negotiating condom use because the sex partners might leave, threaten, or abuse them. Fears associated with negotiating condom use were predicted to be negatively associated with attitudes, subjective norms, and self-efficacy. African American women (N = 560; M age = 20.58) completed assessments of TPB variables at baseline and condom use three months later. Condom negotiation self-efficacy was a significant indicator of behavioral intent while condom use self-efficacy was not. Fear of condom negotiation was negatively associated with all TPB components, which was in turn significantly associated with behavioral intent and condom use. Implications for the TPB, safer sex literature, and STI prevention intervention design are discussed.

This study integrates social network and content analyses to examine the communication behaviors of opinion leaders—such as creating threads and engaging in continuous conversations—in two large cancer-focused online health communities. Guided by the diffusion of innovation theory and the social support literature, we analyzed 951 threads and 10,179 posts and found that a group of opinion leaders (including cancer patients, family caregivers, and cancer survivors) centralized the communities from 2017 to 2018. Opinion leaders’ typical replies to others tended to be a combination of opinion support, emotional support, and network support. Amid their self-created threads, we further identified four themes: cancer history and treatment, health or life condition update, advocacy, and emotional ventilation. Implications for network and content analytics of online cancer communication are discussed.
