During the COVID-19 pandemic, a social lockdown should be put in place and individuals should stay at home. Behavioral change is the only way to prevent the pandemic and overwhelmed healthcare systems until vaccines are available. We aimed to examine the psychological factors that predict staying at home during the COVID-19 pandemic and social lockdown. A total of 1980 participants in Japan completed a survey for this study from 9 to 11 May 2020, when the state of emergency covered all prefectur

Newspaper contents changed profoundly before and after the start of the vaccination crisis. Those newspaper reports potentially had impact on readers' beliefs and actions. Journalists should strive for impartial coverage so readers can make more-informed decisions. Health professionals should be expected to work with journalists to help improve impartiality in newspaper coverage. The Ministry of Health, Labour and Welfare should discus benefits and risks of the HPV vaccination based on the scien

Health-care professionals should consider the use of a perceptually fluent design, plain language, numeracy with an appropriate degree of precision, a limited number of key points, and concrete descriptions that make recipients imagine healthy behavior. Such fluently processed materials that are easy to read and understand have enhanced perspicuity and persuasiveness.

Health professionals should use available guidelines to make existing patient information easy to read and to write easy-to-read patient information, thereby improving readability. Such efforts are needed regardless of the organizations these professionals work at.

The provision of information about cancer is an important aspect of cancer care. Cancer information provided online is expected to meet the needs of information seekers. Whether information needs vary according to tumor site is largely unknown. We aimed to examine similarities and differences in informational needs by cancer type. Data were collected using a questionnaire administered on Japan's largest cancer information website, "Ganjoho service". A total of 2782 free descriptive responses in

Mothers' narrative messages may be persuasive when targeting mothers for promoting HPV vaccination. This may be because mothers can easily relate to and identify with communications from other mothers. However, for effective HPV vaccine communication, further studies are needed to understand more about persuasive differences in terms of statistics, narratives, and narrators. Directions for future research are also suggested.

Background: Cancer screening rates are lower in Japan than in Western countries such as the United States and the United Kingdom. While health professionals publish pro-cancer-screening messages online to encourage proactive seeking for screening, anti-screening activists use the same medium to warn readers against following guidelines. Contents of pro- and anti-cancer-screening sites may contribute to readers’ acceptance of one or the other position. We aimed to use a text-mining method to exam

Vaccine hesitancy is a problem attracting growing attention and concern. In this paper, we discuss why anti-vaccination messages are influential and which pro-vaccine messages can be effective to address vaccine hesitancy from the perspective of dual-process theories of cognitive functioning. The functioning of the human brain can be characterized by two different types of cognitive functioning: intuitive System 1, which is evolutionarily old, fast, and automatic; and analytical System 2, which

It is important to provide information on HPV vaccination and on early detection and early treatment for cervical cancer. Readability is a key aspect in the success of cancer communication using written health information. We reviewed studies assessing the readability of information on HPV vaccination and cervical cancer. We conducted a systematic literature search in June 2021 using four online databases (Medline, CINAHL, PsycArticles, and PsycINFO). Studies that assessed the readability level

Anti-vaccination sentiment exists worldwide and Japan is no exception. Health professionals publish pro-influenza vaccination messages online to encourage proactive seeking of influenza vaccination. However, influenza vaccine coverage among the Japanese population is less than optimal. The contents of pro- and anti-influenza vaccination websites may contribute to readers' acceptance of one or the other position. We aimed to use a text-mining method to examine frequently appearing content on webs
