Although the effectiveness of home-based, behaviorally-oriented treatment programs with the elderly and their families has been well documented, assessment of caregivers' attitudes toward those programs remains rare. To assess the relationship between outcome measures and client and principal caregiver characteristics, 21 client-caregiver dyads, participating in the Elderly Support Project, completed pre- and post-test measures and three follow-up interviews during a 24-month period. The Elderly Support Project focused on behaviorally-oriented home-based treatment of disabled elderly clients at high risk of long-term institutional care. The program was implemented through a series of intervention steps including assessment, baseline data collection, behaviorally-oriented treatment, and follow-up. An analysis of the results showed that at the first follow-up, 74 percent of the clients were still living at home (10 percent had died and 16 percent were institutionalized). At second follow-up, 75 percent of the clients were living in the community (25 percent were deceased). The caregivers' ratings of their relationship with the client, their ability to manage the client's behavior, and the client's mental status at program termination were significantly associated with placement. Client diagnosis, caregiver ratings of target problems, and whether or not the client lived with the caregiver were significantly associated with caregivers' subsequent relational satisfaction scale ratings.
