This study examined the question, “Can a congregate housing program remain constant over a long period of time (13 years) without making some attempt to accommodate to an aging population?” The study question was related to Lawton's two ideal models—constant and accommodating. Findings suggest that, although planning in the direction of the accommodating model did not seem appropriate, neither could the constant model be supported. An alternative, balanced model involving intervention to strengthen the informal network is suggested. The Philadelphia Geriatric Center Multi-Level Assessment Instrument is evaluated.
