The psychometric network of individual flourishing across nationally representative samples from 22 countries.

To effectively promote human flourishing, it is important to understand how the different dimensions of flourishing might be related to one another in different sociocultural contexts. Applying a systems perspective to flourishing, this study uses nationally representative survey cross-sectional data from 22 geographically and culturally diverse countries included in the Global Flourishing Study (N = 202,898) to explore the interrelatedness of the components of individual flourishing captured by the Secure Flourish Measure. A meta-analytic gaussian network aggregation (MAGNA) model was applied to investigate similarities and differences among the interrelations of individual flourishing components across countries. Results revealed a network of mostly positive interrelations among the 12 components, although there was substantial heterogeneity in the strength of associations, especially between life satisfaction, happiness, and mental health. Understanding cross-country differences in light of socio-contextual peculiarities will be crucial for informing the development of targeted interventions to promote flourishing.
