Linking theory and gerontological nursing practice in senior housing.

This article illustrates the use of 2 theoretical models in planning and implementing health programs in senior housing. The Person-Environment Fit Model, developed by Lawton, and the Transitions Theory, developed by Meleis and colleagues, form the basis for understanding the interaction between people and their environments through transitions common in late life. The models and their application to practice are described, with examples at the individual, group, and community levels. Implications and future directions are identified for the use of such models in gerontological nursing practice.
