    Communication to Promote Healthier Behaviors – Understanding the Roles of Channels and Message Formats
    (2016-09-27) Hayashi, Hanae; Kawachi, Ichiro; Viswanath, Kasisomayajula; Tan, Andy
    Communication has been used to change people’s health knowledge, attitudes and behaviors, and it is critical for improving people’s lives, especially those who are in a disadvantaged group. Many studies suggest that communication is a powerful tool when it is used effectively for these population groups. In this dissertation I explored the roles of channels and message formats among vulnerable populations. Paper 1 investigated interpersonal diffusion of health information, specifically health information mavenism among people over age 65 in Japan, identifying the characteristics of health information mavens and whether they behave more healthily or report better health status. The study found that health information mavens can be a potential channel to facilitate word-of-mouth communication among the elderly, who are considered as a disadvantaged group. Paper 2 explored the impact of discrete emotions to Graphic Health Warnings (GHWs) on tobacco-related outcomes among smokers and non-smokers from lower socioeconomic status (SES) in the U.S. The paper researched the relationship between different discrete emotional reactions and smoking cessation-related cognitive outcomes. It demonstrated the importance of focusing on discrete emotional reactions and the intensity of the discrete emotional reactions that GHWs induce, beyond positive or negative valence, on tobacco-related outcomes. Paper 3 examined segmentation, specifically focusing the effectiveness of matched GHWs by race, gender, and chronic disease conditions on cognitive outcomes among smokers in vulnerable populations. It assessed whether the GHWs matched with the image of particular groups, in terms of race, gender and chronic disease conditions, increases risk perception and intention to quit smoking among the intended audience. Segmentation showed the increased effect for risk perception among female-targeted GHWs, however, the increased effect was not shown for other groups and outcomes. Further research is needed to investigate whether segmentation works for matched groups. The findings not only make contribution to the literature by generating new evidence on the role of channels and formats, but also contribute to practice by offering practical implications for program and strategy development in health communications among vulnerable population.

    Socioeconomic Status and Health Communication Inequalities in Japan: A Nationwide Cross-Sectional Survey
    (Public Library of Science, 2012) Ishikawa, Yoshiki; Nishiuchi, Hiromu; Hayashi, Hanae; Viswanath, Kasisomayajula
    Background: Considerable evidence suggests that communication inequality is one potential mechanism linking social determinants, particularly socioeconomic status, and health inequalities. This study aimed to examine how dimensions of health communication outcomes (health information seeking, self-efficacy, exposure, and trust) are patterned by socioeconomic status in Japan. Methods: Data of a nationally representative cross-sectional survey of 2,455 people aged 15–75 years in Japan were used for secondary analysis. Measures included socio-demographic characteristics, subjective health, recent health information seeking, self-efficacy in seeking health information, and exposure to and trust in health information from different media. Results: A total of 1,311 participants completed the questionnaire, giving a response rate of 53.6%. Multivariate logistic regression revealed that education and household income, but not employment, were significantly associated with health information seeking and self-efficacy. Socioeconomic status was not associated with exposure to and trust in health information from mass media, but was significantly associated with health information from healthcare providers and the Internet. Conclusion: Health communication outcomes were patterned by socioeconomic status in Japan thus demonstrating the prevalence of health communication inequalities. Providing customized exposure to and enhancing the quality of health information by considering social determinants may contribute to addressing social disparities in health in Japan.
