Can pre-disaster community resilience enhance post-disaster recovery among older adults? A natural experiment in Iwanuma City after the 2011 Great East Japan Earthquake and Tsunami
As large-scale disasters occur more frequently worldwide, understanding how pre-disaster community resilience influences post-disaster recovery has become imperative for disaster risk-reduction policy and practice. This study investigated whether pre-disaster community resilience helped explain post-disaster subjective recovery following the 2011 Great East Japan Earthquake and Tsunami. We conducted a baseline survey of older residents in Iwanuma…

Paradoxical effects of community social cohesion on mental health and help-seeking among older adults: The role of reputation concern and socioeconomic status
There is no consensus on whether community social cohesion has positive or negative impacts on mental health. In this study, we hypothesized that strong social norms in highly cohesive communities might increase concerns about reputation, which could negatively affect mental health and help-seeking. We analyzed data from 23,672 adults aged 65 years or older from the 2019 wave of the Japan Gerontological Evaluation Study (JAGES). Cross-sectional m…

The Role of Social Capital in Depression During the Covid-19 Pandemic
Depression remains a major concern during the COVID-19 pandemic. Social capital provides support for those struggling with this condition. However, we know little about its multidimensional role as a correlate of mental health. We collected data from 896 participants in three major cities in the United States, Brazil, and Japan between December 31, 2020, and March 3, 2021. Using these data, we conducted a multiple linear regression for correlates…

Resilience Factors Affecting Long-Term Trajectories of Depressive Symptoms in the Aftermath of the Great East Japan Earthquake and Tsunami Among Older Adults
Objectives We examined long-term trajectories of depressive symptoms among older adults following exposure to the 2011 Great East Japan Earthquake and Tsunami. We further characterized the pre- and post-disaster social relationship factors that predicted membership in each trajectory group. Methods Data from 4 time points (including pre-disaster data) were used to analyze the depression trajectories of 2,033 survivors through a group-based trajec…
Do disasters exacerbate socioeconomic inequalities in health among older people
Disasters can exacerbate socioeconomic health disparities because of differential exposure (e.g., socioeconomically disadvantaged groups are more likely to be exposed to disaster-related trauma) and differential vulnerability (disadvantaged groups are more likely to suffer health consequences of exposure to trauma). We sought to test whether health disparities among older adults widened in the area which was directly affected by the 2011 Great Ea…

The psychological determinants of avoiding crowded areas: An international and political investigation
Social isolation is one of the most important measures to reduce clusters of infections. This research aims to explain why people avoided crowded spaces during periods of high global infection of COVID-19 in a cross-national and politically diverse sample. We conducted a cross-cultural survey using Likert-type scale questions (N = 1,196) in New York (n = 313), Brasilia (n = 283), Tokyo (n = 300), and Taipei (n = 300). We ascertained the validity …
Association between housing damage, present bias and delayed-onset post-traumatic stress symptoms among older adults 9 years after a natural disaster
BACKGROUND: Previous studies suggest that experience of natural disasters may heighten present bias. Research also suggests that impaired self-control (in particular, heightened present bias) could be linked to delayed-onset post-traumatic stress symptoms (PTSS) among survivors of natural disasters. We examined a hypothesis that the association between disaster experiences and delayed-onset PTSS is mediated through present bias among older surviv…
Knowledge, Practices and Attitudes towards Silver Diamine Fluoride Therapy among Dentists in Japan: A Mixed Methods Study
In 2021, the World Health Organization included silver diamine fluoride (SDF) as an essential medicine to manage caries in adults and children. SDF was developed in the 1960s, but its use for children became unpopular in Japan because of the decline and low prevalence of early childhood caries. This mixed methods study explored the knowledge, practices and attitudes towards SDF therapy among dentists promoting fluoride use in Japan. It also inves…
