A meta-analysis of published studies that reported correlations between self-ratings and informant ratings of well-being (life-satisfaction, happiness, positive affect, negative affect) was performed. The average self-informant correlation based on 44 independent samples and 81 correlations for a total of 8,897 participants was r = 0.42 [99% credibility interval = 0.39|0.45]. Statistically reliable moderators of agreement were construct (life-satisfaction = happiness > positive affect > negative affect), age of the target participant (older > younger), number of informants (multiple > single), and number of items in the measure (multiple > single). The implications for the validity of self-ratings of well-being as indicators of well-being are discussed.
