The purpose of this research project is to develop concepts for doing cost-benefit analyses for governmental and nonprofit homes. Such concepts should facilitate a differential diagnosis which recognizes the wide individual differences among those served. Developing relevant concepts is a first step in measurement. An aim is to develop appropriate concepts and instruments that will make an ordinal measurement of resident satisfaction possible. This study makes no effort to develop monetary measures of either costs or benefits. These measures and the related cost-benefit analyses must await further developments. Of the home's employees, the nurses and nurses' assistants usually have the most prolonged and intimate contact with the residents. The nurses and nurses' assistants often are the home personified in that they provide the bulk of a home's services to the less able residents. This explains why the environment of the home, which includes the values, needs, and attitudes of nurses and nurses' assistants, is believed to influence resident satisfaction.
