Exploratory case studies investigated the day care benefit from the multiple perspectives of the person with dementia, caregiver, and day care worker. The routines, daily processes, and factors promoting benefit were reported. The day care client was also queried to explore their ability to contribute useful information about their care environment. The adult day care is primarily a social occasion for its clients, who enjoy the benefits of companionship and interaction. Day cares were differentiated by the environmental features: worker:client ratio, size, suitability of the site for intended purpose, quality of client-worker relationships, and quality of the activities offered. The quality of each of these features is an important component in the day care environment. All components at their highest quality are not necessary for the environment to be beneficial. The most important factors contributing to day care quality were workers who (1) communicated safety to the client through a relaxed, uncritical environment, and (2) facilitated client stimulation through activity and personal interaction, satisfying the clients’ basic needs to be safe and occupied. This evaluation was comprised of: two sets of case studies. Each evaluation was concurrently conducted and consistently designed. Participant observation and survey were the primary methods of data collection. Informed consent was sought from day care clients with dementia, family caregivers, and day care workers.
