Abstract
A set of ratings by others was obtained in conjunction with a collection of self-report data on subjective quality of life. Respondents and two or three "relevant others" nominated by them rated the respondents' satisfaction with aspects of their life. The correlations between respondent-respondent, respondent-other, and other-other ratings provide estimates of the convergent and discriminant validity of the self-ratings and ratings by others. The results of these analyses provide evidence for the external validity of self-ratings in the quality of life area. More importantly, they illustrate the possibility of using ratings by other as a validation criterion for self-ratings in general. The validity of ratings by others who vary in their relationship with their respondents is also explored, and suggestions for further uses of ratings by others are provided
