Although aging well socially (Engagement with Life) is as important as aging well personally (Illness Avoidance and Functioning) (Rowe & Kahn, 1998), it has received less research attention. A Caring (CE) and a Productive (PE) form of Engagement were derived from an analysis of Chinese cultural meanings of engagement, and combined with Illness Avoidance and Functioning to form a 4-factor model. Confirmatory factor analysis based on 2,970 Hong Kong Chinese (40 to 74 years) showed a good model fit that was replicated a year later with 2,120 of the original sample. Further analysis led to a more parsimonious model where Illness Avoidance and Functioning converged into a single second-order factor whereas CE and PE remained as distinct first-order factors. The results supported the differentiation of Rowe and Kahn's Engagement with Life component into Caring and Productive Engagements. (Contains 4 tables, 2 figures and 1 footnote.)
