The Contribution of Positive and Negative Affect to Life Satisfaction across Age

People rely on their recent emotional experiences when constructing life satisfaction judgments. However, the role of positive and negative affect in life satisfaction across different age groups has rarely been examined in prior research. This study sought to investigate the contribution of positive and negative affect to life satisfaction across five age groups in a large sample of Serbians between 16 and 65 years of age (N = 3287, 59.9% females). Multi-group structural equation modeling was used to establish measurement invariance and to examine the relationships between affect and life satisfaction across the age groups. Full metric invariance was supported for life satisfaction and positive and negative affect across the groups. The results showed that positive affect had strong effects on life satisfaction across the groups, whereas negative affect had weak or nonsignificant effects. The effects of positive and negative affect on life satisfaction were found to be invariant across age groups. Our findings indicate that people rely more on positive emotional experiences than on negative emotional experiences when constructing life satisfaction judgments, and that age does not moderate the effects of affective experiences on life satisfaction.
