In an extension of Louden's work, this study investigated identity development across the lifespan by applying Erickson's and Marcia's identity constructs to two developmental models, the selective optimization and compensation model and a holistic wellness model. Data was gathered from traditionally aged college freshmen and adults older than 60 years of age. Uncommitted identity statuses and work and leisure wellness domains were endorsed across both groups, suggesting that identity for these groups is in a state of fluctuation yet entailing participation as a productive member of society.

Coping method utilization and overall wellness varied between the two age groups. Conceptually, the SOC model can be viewed as embedded within each of the wellness domains such that selection, optimization, and compensation activities may be carried out within each of the various domains and …
