Although its exact definition varies, it is usually measured as an aggregation of well-being across several life domains and may include both subjective and objective components.Life satisfaction is generally measured using a self-report method.A common measurement for life satisfaction is questionnaires.
how much positive and/or negative affect a person generally experiences over any given period of time).
"Quality of life" has also been studied as a conceptualization of SWB.
Additionally, heritability estimates are inconsistent across studies.
Further evidence for a genetically influenced predisposition to SWB comes from findings that personality has a large influence on long-term SWB.
Due to the specific focus on the subjective aspects of well-being, definitions of SWB typically exclude objective conditions such as material conditions or health, although these can influence ratings of SWB.
Definitions of SWB therefore focus on how a person evaluates his/her own life, including emotional experiences of pleasure versus pain in response to specific events and cognitive evaluations of what a person considers a good life.
To gain more accurate results, other methods of measurement have been used to determine one’s SWB.
Another way to corroborate or confirm that the self-report results are accurate is through informant reports.
Components of SWB relating to affect include positive affect (experiencing pleasant emotions and moods) and low negative affect (experiencing unpleasant, distressing emotions and moods), as well as "overall affect" or "hedonic balance", defined as the overall equilibrium between positive and negative affect, and usually measured as the difference between the two. One is Affective Balance and the other is Life Satisfaction.
