Subjective well-being (SWB) comprises people's longer-term levels of pleasant affect, lack of unpleasant affect, and life satisfaction. It displays moderately high levels of cross-situational consistency and temporal stability. Self-report measures of SWB show adequate validity, reliability, factor invariance, and sensitivity to change. Despite the success of the measures to date, more sophisticated approaches to defining and measuring SWB are now possible. Affect includes facial, physiological, motivational, behavioral, and cognitive components. Self-reports assess primarily the cognitive component of affect, and thus are unlikely to yield a complete picture of respondents' emotional lives. For example, denial may influence self-reports of SWB more than other components. Additionally, emotions are responses which vary on a number of dimensions such as intensity, suggesting that mean levels of affect as captured by existing measures do not give a complete account of SWB. Advances in cognitive psychology indicate that differences in memory retrieval, mood as information, and scaling processes can influence self-reports of SWB. Finally, theories of communication alert us to the types of information that are likely to be given in self-reports of SWB. These advances from psychology suggest that a multimethod approach to assessing SWB will create a more comprehensive depiction of the phenomenon. Not only will a multifaceted test battery yield more credible data, but inconsistencies between various measurement methods and between the various components of well-being will both help us better understand SWB indictors and group differences in well-being. Knowledge of cognition, personality, and emotion will also aid in the development of sophisticated theoretical definitions of subjective well-being. For example, life satisfaction is theorized to be a judgment that respondents construct based on currently salient information. Finally, it is concluded that measuring negative reactions such as depression or anxiety give an incomplete picture of people's well-being, and that it is imperative to measure life satisfaction and positive emotions as well.
