N2 - Negative self-perceptions of aging (SPA) have been linked to poor physical health and functioning outcomes in late life, yet the direction of this relationship remain unclear. Using data from the Australian Longitudinal Study of Aging, we investigated the directionality of the dynamic relationship between self-perceptions of aging and physical functioning in 1,212 adults 65 years and above (mean age = 76.89, SD = 6.12) over 5 waves (up to 16 years). Bivariate Dual Change Score Models (BDCSM) revealed that the best fitting model for the data was that which allowed SPA to predict change in physical functioning over time lags of 1 year. The direction of the relationship remained after controlling for age, gender, partner status, residential care, number of medical conditions, self-rated health, and psychological well-being. Findings suggest that more positive SPA may be protective of decline in physical functioning in late life.
