Health literacy reductionism
Health literacy is one of the most influential concepts in contemporary health promotion. However, its success has created an explanatory shadow. Specifically, complex problems of communication, participation, and engagement are often reduced to deficits in individual health literacy, while relational, organizational, and structural explanations are backgrounded. This paper conceptualized this repetitive explanatory pattern as “health literacy re…
Responsibility frame for depression in Japanese newspapers
Using quantitative content analysis, we explored how Japanese newspapers framed causal and solution responsibility for depression and whether they attributed more responsibility to individuals or society. The longitudinal changes in framing were also examined. Articles referring to depression were selected from the Yomiuri Shimbun, the Asahi Shimbun, and the Mainichi Shimbun, which are nationwide daily newspapers published in Japan between 1993 a…
The curse of knowledge in medical communication
The curse of knowledge—the difficulty of imagining what it is like not to know something once one knows it—is a well-documented cognitive bias, yet it has rarely been applied to clinical communication. This paper proposes it as an upstream mechanism linking three domains often treated as separate: health literacy, epistemic injustice, and medical invalidation. Using a narrative synthesis across multiple scholarly traditions, we argue that clinici…
Evaluating the understandability and actionability of Japanese human papillomavirus vaccination educational materials on cervical cancer
Educational materials about human papillomavirus (HPV) vaccination must be easy to understand and must support recommended behaviors regardless of readers’ health literacy levels. The purpose of this study was to evaluate the understandability, actionability, and comprehensiveness of HPV vaccination educational materials in Japan. From August to September 2023, we obtained HPV vaccination educational materials from the central government, local g…
Redefining health communication through narrative intersection
We aimed to propose a new conceptualization of health communication that mitigates the limitations of traditional one-way models by introducing a relational, narrative-based approach that emphasizes mutual understanding. This paper critiques existing definitions and proposes an alternative framework by reviewing interdisciplinary literature on Narrative Medicine, narrative identity theory, and health communication research. The paper introduces “…
Associations between lifestyle habits and family members’ health literacy in middle-aged adults with metabolic syndrome
Background Health literacy has gained importance as a factor related to health behaviors and the risk of developing metabolic syndrome (MetS). Although the health literacy of family members may affect lifestyle habits among individuals with MetS, few studies have examined these relationships. We examined the associations between lifestyle habits (dietary habits, exercise, drinking, and smoking) among individuals with MetS and their family members…
Development and psychometric evaluation of the Infertility Public Stigma Scale for Japanese women
Introduction: Women undergoing infertility treatment are often tagged with negative labels, subjected to negative reactions and behaviors by laypeople (public stigma), and they internalize these negative values (self-stigma). As self-stigma is associated with poor mental health, a measure is needed to determine the current state of public stigma in Japan and to evaluate the effectiveness of efforts to reduce it. However, existing instruments to m…
The direct effects of media exposure on behaviors aimed at preventing Covid-19 and its indirect effects as mediated by interpersonal communication
Objective: We aimed to examine the direct effects of exposure to media information about infection-preventing behavior and its indirect effects via interpersonal communication at two time points during the pandemic. Methods: In August 2020 and August 2021, a web-based survey of Japanese people under a declared state of emergency was conducted. We collected sociodemographic data and data on seven types of exposure to media information, three types…
Public perception of the resumption of HPV vaccine recommendation in Japan
On 12 November 2021, after a stagnation of 8.5 years, Japan decided to resume proactive recommendations for HPV vaccines. However, it is not known how the public reacted to the resumption of proactive recommendations for HPV vaccines, which are key elements in health communication that promote HPV vaccination. This study aimed to capture discussions on HPV vaccination on Twitter and to identify user characteristics, sentiments, discussed themes a…
