Fulfilling the Promise of Well-Being Science: the Quest for Conceptual and Measurement Precision.

Research on well-being has grown exponentially in the last 30 years, employing a variety of constructs and operational measures to produce a wealth of empirical research. This has led to a rich and high-impact, yet somewhat fragmented body of work. The target article by Park and colleagues initiates a valuable conversation aimed at converging on a shared conceptual definition of well-being. A rigorous program of further theoretical analysis and new research is needed to identify the boundaries as well as the core of well-being, and to document facets that are both statistically distinct and meaningful. The resulting conceptual clarity and measurement precision will facilitate mechanism-level research on causes and consequences of well-being, providing a strong foundation for scalable interventions.
