A construct validation study of life satisfaction was completed with a modified random area probability sample of 325 older persons (M=73.0, SD=8.2) residing in the Phoenix metropolitan area. Internal consistency reliability estimates for the Life Satisfaction Index Form Z and both subscales of the Affect Balance Scale were consistent with previous reports. Within self-ascribed handicapped and nonhandicapped groups, six life satisfaction measures generally correlated more highly with each other than with an alcohol use measure, suggesting adequate convergent-discriminant validity. Finally, the handicapped group had lower life satisfaction than the nonhandicapped group, and stepdown F tests indicated some redundancy among the life satisfaction measures.
