The determinants of the quality of life across the world
摘要
This study explores the complex interplay between government support, mental well-being, and social relationships in determining individuals’ quality of life across a diverse sample of 35 countries. Using Structural Equation Modeling (SEM), the research identifies the relative contributions and mediating mechanisms through which institutional, psychological, and interpersonal factors influence life satisfaction. The empirical findings underscore the paramount role of mental health, revealing that psychological variables—particularly loneliness and perceived stress—exert the most significant direct effects on individuals’ overall life satisfaction. In addition, social trust and the quality of interpersonal relationships emerge as important contributors, highlighting the value of cohesive and supportive social environments. Interestingly, while participation in social activities does not exert a direct effect on life satisfaction, it is found to be indirectly influenced by broader governmental and social contexts, suggesting a nuanced pathway through which institutional support and social cohesion facilitate well-being. Therefore, to enhance quality of life at the population level, governments must look beyond material or administrative support and focus more explicitly on fostering mental well-being and social connectedness within communities.
