This two-wave longitudinal study (performed pre-COVID), using both quantitative and qualitative data, investigated college students’ influenza vaccine hesitancy and confidence using the theory of planned behavior (TPB). At Time 1, college students (n = 277) completed TPB measures and reported past influenza vaccine behavior. At Time 2 (30 days later), participants indicated whether they received the influenza vaccine since Time 1. At Time 2, participants who indicated that they had not received the influenza vaccine since Time 1 also described their most important reasons for not doing so. The TPB model fit the quantitative data well; direct paths from attitude and norms to intention, and from intention to future behavior, were strong and significant. The TPB model explained 71% of the variance in intention and 28% of the variance in future behavior. Neither perceived behavioral control nor past behavior improved the model’s ability to predict intentions or future behavior. From the qualitative data, participants’ reasons for not getting vaccinated focused on perceived behavioral control (e.g., time cost) and attitudes (e.g., unimportance and low susceptibility). Theoretical implications for message development are discussed.

A large body of research demonstrates that concussions are exceedingly common and extremely difficult to detect. Despite medical efforts to develop sophisticated tools to detect concussions, research continues to demonstrate that proper detection relies on prompt and thorough symptom reporting from the injured athlete. In the context of sports, such reporting requirements are complicated by systems that reward athletic performance. This study seeks to provide student athletes who play NCAA Division I high-contact sports with a theoretically driven intervention to improve their attitudes and behavior toward concussion reporting. Division I student athletes (N = 345) viewed one of three conditions: an NCAA handout consistent with current practices, the experimental video, or a non-treatment control video, then responded to questions regarding attitudes and behaviors toward concussion reporting. Overall, results support the video’s effectiveness in changing perceptions of concussion injuries. Nuances of the findings lead to a discussion for practical implications to transform concussion-reporting attitudes and behaviors among athletes.

Despite a significant legal transformation of the organ donation system in China, the public's willingness to become organ donors remains low. This study provides the first empirical examination of how Chinese newspaper coverage reflects the complex interplay among multifaceted factors associated with the stagnant donation rate. Using framing as the primary theoretical lens, we analyzed 923 organ donation newspaper articles from 2000 to 2018 in terms of topics, facilitators and barriers, valence, and policy development. The three most common topics emphasized were: a new official information release regarding organ donation promotion; the challenges of promoting organ donation in social, cultural, and legal contexts; and the positive emotional appeals of organ donors, coordinators, and transplant surgeons. Findings suggest that the values that facilitators of and barriers to organ donation represent can be culturally favored but in conflict with each other. Sharp increases in the presence of policy development framing are associated with the official announcements of new legislation. A better understanding of trending topics and interacting influence from facilitators and barriers is imperative for developing culturally tailored messages to raise awareness about organ donation promotion.
