This article reports the development and validation of a scale to measure global life satisfaction, the Satisfaction With Life Scale (SWLS). Among the various components of subjective well-being, the SWLS is narrowly focused to assess global life satisfaction and does not tap related constructs such as positive affect or loneliness. The SWLS is shown to have favorable psychometric properties, including high internal consistency and high temporal reliability. Scores on the SWLS correlate moderately to highly with other measures of subjective well-being, and correlate predictably with specific personality characteristics. It is noted that the SWLS is Suited for use with different age groups, and other potential uses of the scale are discussed.

W. Wilson's (1967) review of the area of subjective well-being (SWB) advanced several conclusions regarding those who report high levels of "happiness." A number of his conclusions have been overturned: youth and modest aspirations no longer are seen as prerequisites of SWB. E. Diener's (1984) review placed greater emphasis on theories that stressed psychological factors. In the current article, the authors review current evidence for Wilson's conclusions and discuss modern theories of SWB that stress dispositional influences, adaptation, goals, and coping strategies. The next steps in the evolution of the field are to comprehend the interaction of psychological factors with life circumstances in producing SWB, to understand the causal pathways leading to happiness, understand the processes underlying adaptation to events, and develop theories that explain why certain variables differentially influence the different components of SWB (life satisfaction, pleasant affect, and unpleasant affect).In 1967, Warner Wilson presented a broad review of subjective well-being (SWB) research entitled, "Correlates of Avowed Happiness." Based on the limited data available at that time, Wilson concluded that the happy person is a "young, healthy, welleducated, well-paid, extroverted, optimistic, worry-free, religious, married person with high self-esteem, job morale, modest aspirations, of either sex and of a wide range of intelligence" (p. 294). In the three decades since Wilson's review, investigations into SWB have evolved. Although researchers now know a great deal more about the correlates of SWB, they are less interested in simply describing the demographic characteristics that correlate with it. Instead, they focus their effort on understanding the processes that underlie happiness. This trend represents a greater recognition of the central role played by people's goals, coping efforts, and dispositions. In this article, we review research on several major theoretical approaches to well-being and then indicate how these theories clarify the findings on demographic correlates of SWB.Throughout the review we suggest four directions that researchers should pursue in the decades ahead. These are by no means the only questions left to answer, but we believe they are the most interesting issues left to resolve. First, the causal direction of the correlates of happiness must be examined through more sophisticated methodologies. Although the causal priority of demographic factors such as marriage and income is intuitively appealing, it is by no means certain. Second, researchers must focus greater attention on the interaction between internal factors (such as personality traits) and external circumstances. As we shall see, demographic factors have surprisingly small effects on SWB, but these effects may depend on the personalities of those individuals being studied. Thus, future research must take Person X Situation interactions into account. Third, researchers must strive to understand the processes underlying adaptation. Consid...

The literature on subjective well-being (SWB), including happiness, life satisfaction, and positive affect, is reviewed in three areas: measurement, causal factors, and theory. Psychometric data on single-item and multi-item subjective well-being scales are presented, and the measures are compared. Measuring various components of subjective well-being is discussed. In terms of causal influences, research findings on the demographic correlates of SWB are evaluated, as well as the findings on other influences such as health, social contact, activity, and personality. A number of theoretical approaches to happiness are presented and discussed: telic theories, associationistic models, activity theories, judgment approaches, and top-down versus bottom-up conceptions.Throughout history philosophers considered happiness to be the highest good and ultimate motivation for human action. Yet for decades psychologists largely ignored positive subjective well-being, although human unhappiness was explored in depth. In the last decade behavioral and social scientists have corrected this situation, and theoretical and empirical work is emerging at an increasingly faster pace. In 1973 Psychological Abstracts International began listing happiness as an index term, and in 1974 the journal Social Indicators Research was founded, with a large number of articles devoted to subjective well-being (SWB). For a comprehensive bibliography of the burgeoning SWB literature, see Diener and Griffin (in press). Excellent reviews of the history and philosophy of happiness and related terms are available (

Numerous studies show that happy individuals are successful across multiple life domains, including marriage, friendship, income, work performance, and health. The authors suggest a conceptual model to account for these findings, arguing that the happiness-success link exists not only because success makes people happy, but also because positive affect engenders success. Three classes of evidence-crosssectional, longitudinal, and experimental-are documented to test their model. Relevant studies are described and their effect sizes combined meta-analytically. The results reveal that happiness is associated with and precedes numerous successful outcomes, as well as behaviors paralleling success. Furthermore, the evidence suggests that positive affect-the hallmark of well-being-may be the cause of many of the desirable characteristics, resources, and successes correlated with happiness. Limitations, empirical issues, and important future research questions are discussed.

One area of positive psychology analyzes subjective well-being (SWB), people's cognitive and affective evaluations of their lives. Progress has been made in understanding the components of SWB, the importance of adaptation and goals to feelings of well-being, the temperament underpinnings of SWB, and the cultural influences on well-being. Representative selection of respondents, naturalistic experience sampling measures, and other methodological refinements are now used to study SWB and could be used to produce national indicators of happiness.

Measures of well-being were created to assess psychological flourishing and feelings-positive feelings, negative feelings, and the difference between the two. The scales were evaluated in a sample of 689 college students from six locations. The Flourishing Scale is a brief 8-item summary measure of the respondent's self-perceived success in important areas such as relationships, self-esteem, purpose, and optimism. The scale provides a single psychological well-being score. The measure has good psychometric properties, and is strongly associated with other psychological well-being scales. The Scale of Positive and Negative Experience produces a score for positive feelings (6 items), a score for negative feelings (6 items), and the two can be combined to create a balance score. This 12-item brief scale has a number of desirable features compared to earlier measures of positive and negative emotions. In particular, the scale assesses with a few 123Soc Indic Res (2010) 97:143-156 DOI 10.1007 items a broad range of negative and positive experiences and feelings, not just those of a certain type, and is based on the amount of time the feelings were experienced during the past 4 weeks. The scale converges well with measures of emotions and affective well-being.

The Satisfaction With Life Scale (SWLS) was developed to assess satisfaction with the respondent's life as a whole. The scale does not assess satisfaction with life domainssuch as health or finances but allows subjects to integrate and weight these domains in whatever way they choose. Normative data are presented for the scale, which shows good convergent validity with other scales and with other types of assessments of subjective well-being. Life satisfaction as assessed by the SWLS shows a degree of temporal stability (e.g., .54 for 4 years), yet the SWLS has shown sufficient sensitivity to be potentially valuable to detect change in life satisfaction during the course of clinical intervention. Further, the scale shows discriminant validity from emotional well-being measures. The SWLS is recommended as a complement to scales that focus on psychopathology or emotional well-being because it assesses an individuals' conscious evaluative judgment of his or her life by using the person's own criteria.

Subjective well-being (SWB), people's emotional and cognitive evaluations of their lives, includes what lay people call happiness, peace, fulfillment, and life satisfaction. Personality dispositions such as extraversion, neuroticism, and self-esteem can markedly influence levels of SWB. Although personality can explain a significant amount of the variability in SWB, life circumstances also influence long-term levels. Cultural variables explain differences in mean levels of SWB and appear to be due to objective factors such as wealth, to norms dictating appropriate feelings and how important SWB is considered to be, and to the relative approach versus avoidance tendencies of societies. Culture can also moderate which variables most influence SWB. Although it is challenging to assess SWB across societies, the measures have some degree of cross-cultural validity. Although nations can be evaluated by their levels of SWB, there are still many open questions in this area.
