 This entry focuses on subjective well-being studies, since that work is standardly deemed “happiness” research. But psychological research on well-being can take other forms, notably in the “eudaimonic”—commonly opposed to “hedonic”—literature, which assesses a broader range of indicators taken to represent objective human needs, such as meaning, personal growth, relatedness, autonomy, competence,  etc.[15]  (The assimilation of subjective well-being to the “hedonic” realm may be misleading, since life satisfaction seems primarily to be a non-hedonic value, as noted earlier.) Other well-being instruments may not clearly fall under either the “happiness” or eudaimonic rubrics, for instance extending subjective well-being measures by adding questions about the extent to which activities are seen as meaningful or worthwhile (White and Dolan 2009). An important question going forward is how far well-being research needs to incorporate indicators beyond subjective well-being.
