A two-factor model of successful aging

Objectives. To propose and test a conceptual two-factor model of successful aging that includes objective and subjective components. Methods. Data were derived from 5,688 persons aged 50-74 years living in New Jersey who participated in the ORANJ BOWL panel. Participants were recruited using random digit dial procedures and interviewed by telephone. A measurement model was developed and tested using data from two independent samples (each n = 1,000); a structural model examining the effects of age and gender was tested using data from another 3,688 people. Results. Confirmatory factor analyses provided support for a multidimensional model incorporating objective criteria and subjective perceptions. Age and gender were associated with objective but not subjective success. Discussion. Results add rigor to the measurement of a construct that has intrigued philosophers and scientists for hundreds of years, providing the empirical foundation on which to build research about successful aging.
