Subjective well-being and its domains across different age groups: an Israeli sample.

Subjective well-being (SWB) across the life span was studied in a representative Israeli sample by a national survey of 1183 subjects, ranging from 18 to 80 years of age. Subjects were given "life scales", on which they rated their SWB in their present life, as well as their satisfaction regarding health, relations with friends, family, work, economic status, sense of personal achievement, and sense of control. The results indicate that: (a) SWB is negatively correlated with chronological age; (b) the relative strength of most of SWB domains changes in the different age groups; (c) SWB is best explained by different sets of domains in different age groups; and (d) economic status is the strongest domain, accounting for SWB in 6 out of 8 age groups. Explanations for these results confronted the developmental view of changing tasks across the life span vs cohort-based differences between the age groups. The decreasing number of domains that account for SWB variance with progressing age, as well as some unexpected findings with regard to the oldest age group (71-80) are also discussed.
