Demographic Variation in Inner Peace Across 22 Countries: A Cross-National Analysis of the Global Flourishing Study
Although peace is invariably regarded as a universal good, most research focuses on ‘outer’ forms (e.g., societal relations), with little attention to ‘inner’ peace (IP, i.e., tranquil states of mind). This may reflect the Western-centrism of academia, with low arousal positive states like IP being relatively undervalued in the West. But alongside broader efforts to redress such Western-centricity, an emergent literature is now exploring this con…
Gender differences in subjective wellbeing in Japan: An intersectionality approach
Analyzed gender differences in wellbeing across diverse demographic groups. • Employed a multidimensional measure of wellbeing to capture its complexity. • Found that women generally reported higher wellbeing scores than men. • No wellbeing gender gap found for teens, young adults, and single parents. Studies on gender differences in wellbeing often use narrowly defined wellbeing measures and only focus on overall comparison of men and women. Thi…
Strangers, Friends, and Everything Between: Sociodemographic Variation in Social Relationship Quality Across 22 Countries
While prior research has demonstrated that social relationships meaningfully shape health and well-being, less is known about how subjective evaluations of the quality of one’s relationships differ across national contexts and across sociodemographic groups within different countries. Using data from the Global Flourishing Study, a large international sample of 202,898 adults from 22 countries, we examined the average level and distributions of s…
Demographic Variation in Balance in Life Across 22 Countries: A Cross-National Analysis of the Global Flourishing Study
The importance of balance has been selectively acknowledged in modern scholarship through notions such as work-life balance. However, the broader notion of balance in life has remained underappreciated. This may reflect the Western-centric nature of academia, with balance having received less attention in the West compared to other cultures. But aligning with efforts to make scholarship more globally inclusive, an emergent literature is exploring…
Childhood Predictors of Dispositional Forgivingness in Adulthood: A Cross-National Analysis with 22 Countries
A robust body of empirical evidence suggests that forgiveness of others is positively related to individual wellbeing. However, less empirical work has been done to identify the factors that may help children not only forgive better during childhood but also develop into adults who practice forgiveness more consistently. To support a population health agenda aimed at the promotion of forgiveness, further research is needed to identify potential d…
Associations of home confinement during Covid-19 lockdown with subsequent health and well-being among UK adults
During the COVID-19 pandemic, the United Kingdom (UK) government introduced public health safety measures to mitigate the spikes in infection rates. This included stay-at-home orders that prevented people from leaving their homes for work or study, except for urgent medical care or buying essential items. This practice could have both short and long-term implications for health and wellbeing of people in the UK. Using longitudinal data of 10,630 …
Pre-disaster income inequality and post-disaster mental health: A natural experiment from the 2011 Great East Japan Earthquake and Tsunami
Community-level social capital and subsequent health and well-being among older adults in Japan: An outcome-wide longitudinal approach
There is inconsistent evidence on the association between community-level social capital and the health or well-being of older adults. This study examined the association between community-level social capital and multidimensional health and well-being outcomes using an outcome-wide approach. We used data from the Japan Gerontological Evaluation Study, a nationwide cohort study of Japanese older adults (analytic samples: 47,227 for outcomes obtai…
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…
Estimating the heterogeneous effect of life satisfaction on cognitive functioning among older adults: Evidence of US and UK national surveys
The emerging field of positive psychology suggests higher life satisfaction, a form of psychological well-being, may improve cognitive functioning. Although evidence exists for population-average associations between psychological well-being and better cognitive function, little is known about how the relationship varies across individuals. We analyzed a national sample of US and UK adults aged ≥50 from the Health and Retirement Study (HRS) (n = …
Complexifying Individualism Versus Collectivism and West Versus East: Exploring Global Diversity in Perspectives on Self and Other in the Gallup World Poll
A wealth of research has suggested the West tends toward individualism and the East toward collectivism. We explored this topic on an unprecedented scale through two new items in the 2020 Gallup World Poll, involving 121,207 participants in 116 countries. The first tapped into orientations toward self-care versus other-care (“Do you think people should focus more on taking care of themselves or on taking care of others?”). The second enquired int…
Are loneliness and social isolation equal threats to health and well-being? An outcome-wide longitudinal approach
The detrimental effects of loneliness and social isolation on health and well-being outcomes are well documented. In response, governments, corporations, and community-based organizations have begun leveraging tools to create interventions and policies aimed at reducing loneliness and social isolation at scale. However, these efforts are frequently hampered by a key knowledge gap: when attempting to improve specific health and well-being outcomes…

Social isolation and subsequent health and well-being in older adults: A longitudinal outcome-wide analysis
Global Trends of Mean and Inequality in Multidimensional Wellbeing: Analysis of 1.2 Million Individuals From 162 Countries, 2009–2019
INTRODUCTION: Human flourishing is a multidimensional concept characterized by a state of complete wellbeing. However, much of the prior research on wellbeing has principally focused on population averages assessed using a single item of wellbeing. This study examined trends in population averages and inequalities for a multidimensional index of wellbeing and compared emergent patterns with those found for Cantril's ladder, a measure of life sati…

Does community-level social capital mitigate the impact of widowhood & living alone on depressive symptoms: A prospective, multi-level study
The Global Financial Crisis and Overweight among Children of Single Parents: A Nationwide 10-Year Birth Cohort Study in Japan
Evidence suggests that socioeconomically disadvantaged children may experience a greater increase in overweight risk during macroeconomic downturns. We examined whether inequalities in the risk of overweight between Japanese children from single- and two-parent households increased after the 2008 global financial crisis. We used data from ten waves (2001 to 2011) of a nationwide longitudinal survey following all Japanese children born within 2 we…
Retirement and mental health: Does social participation mitigate the association? A fixed-effects longitudinal analysis
Retirement may increase depressive symptoms among Japanese older adults, particularly men from lower occupational class backgrounds. Encouraging recreational social participation may mitigate the adverse effects of retirement on mental health of Japanese older men
Informal and Formal Social Support and Caregiver Burden: The Ages Caregiver Survey
BACKGROUND: We examined the associations of informal (eg, family members and friends) and formal (eg, physician and visiting nurses) social support with caregiver's burden in long-term care and the relationship between the number of available sources of social support and caregiver burden. METHODS: We conducted a mail-in survey in 2003 and used data of 2998 main caregivers of frail older adults in Aichi, Japan. We used a validated scale to assess…
