Subjective Well-Being and Life Satisfaction
Subjective well-being is one of the foundational constructs in modern positive psychology because it asks how people evaluate the quality of their own lives through both emotional experience and cognitive judgment. This article examines the conceptual structure of SWB, its three classic components of life satisfaction, positive affect, and negative affect, and the psychometric tools that made happiness scientifically measurable. It also explores cross-cultural comparison, the role of SWB in economics and public policy, and the limitations of self-report-based well-being research. The result is a clearer account of subjective well-being as an essential but incomplete dimension of flourishing within a broader science of human development.
