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 May 9 to 11, 2020, when the state of emergency covered all prefectures in the country. Self-reported behavior in terms of staying at home, the perceived severity of the pandemic, vulnerability to the pandemic, response efficacy, and self-efficacy based on protection motivation theory were assessed. Multiple regression analysis showed that perceived severity (standardized β = 0.11, p < 0.001) and self-efficacy (standardized β = 0.32, p < 0.001) significantly predicted greater levels of staying at home, after controlling for socio-demographics. However, perceived vulnerability and response efficacy did not. To encourage people to stay at home during the pandemic and social lockdown, increasing the perceived severity of infection by COVID-19 and self-efficacy in terms of exercising restraint with respect to going out may consequently encourage people to stay at home.

Many studies have explored the association between health literacy and health-care utilization; however, the majority assessed functional health literacy in terms of basic skills. Japan's health-care and medical examination system in workplaces is different from that of other major countries. This study examined the relationship of health literacy with health-care use (emergency visit, hospitalization, dental checkup, and health checkup or cancer screening); it focused on differences by occupation and health-care service utilization among general Japanese using the communicative and critical health literacy scale. We conducted a cross-sectional observational study of 1002 Japanese residents. Through a questionnaire, we investigated socioeconomic status, health status, health-care use, and health literacy. Among all participants and non-workers, logistic regression analyses revealed that health literacy was significantly associated with health checkup or cancer screening after adjusting for sex, age, marital status, education, and having a disease or disorder (adjusted odds ratio [OR] = 1.431, 95% confidence interval [CI], 1.131–1.810; adjusted OR = 1.614, 95% CI, 1.114–2.339, respectively). Among workers, we observed no significant association between health literacy and health-care utilization. These results indicate that health literacy is closely related to use of preventive health-care. Japan's health-care system in workplaces may promote use of preventive health-care services regardless of health literacy, whereas improving health literacy may be more critical among non-workers.

Highlights We examined persuasive message types in terms of a narrator encouraging self-restraint. Messages from a governor, an expert, a physician, a patient, and a resident were compared. The message from a physician increased intention to stay at home the most. The physician’s message conveyed the crisis of collapse of the medical system.

BackgroundThe human papillomavirus (HPV) vaccination percentage among age-eligible girls in Japan is only in the single digits. This signals the need for effective vaccine communication tactics. This study aimed to examine the influence of statistical data and narrative HPV vaccination recommendation massages on recipients’ vaccination intentions.MethodsThis randomized controlled study covered 1,432 mothers who had daughters aged 12–16 years. It compared message persuasiveness among four conditions: statistical messages only; narrative messages of a patient who experienced cervical cancer, in addition to statistical messages; narrative messages of a mother whose daughter experienced cervical cancer, in addition to statistical messages; and a control. Vaccination intentions to have one’s daughter(s) receive the HPV vaccine before and after reading intervention materials were assessed. Statistical analysis was conducted using analysis of variance with Tukey’s test or Games–Howell post hoc test, and analysis of covariance with Bonferroni correction.ResultsVaccination intentions after intervention in the three intervention conditions were higher than the control condition (p < 0.001). A mother’s narrative messages in addition to statistical messages increased HPV vaccination intention the most of all tested intervention conditions. A significant difference in the estimated means of intention with the covariate adjustment for baseline value (i.e., intention before intervention) was found between a mother’s narrative messages in addition to statistical messages and statistical messages only (p = 0.040).DiscussionMothers’ 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.
