Abstract
This research aimed to clarify the dimensionality of the Life Satisfaction Index A. A multiple indicator structural equation model that includes 11 items loading on three first-order factors and one second-order factor was proposed to delineate the structure of the Life Satisfaction Index A. This model was examined empirically by using data from the 1974 National Council on Aging/Harris survey, Myths and Realities of Aging in America. The proposed formulation was supported and consistently replicated across four randomly divided subsamples.
