The number of foster children and their psychological and medical morbidity are growing. To gain insight into how to recruit and retain foster homes, characteristics of 64 foster families were determined by interview. Foster parents had low-to-moderate incomes, were approaching middle age, had underutilized home space, and wanted more children. Most enjoyed foster care and planned to continue. Twenty-three percent of the 64 had half of all foster children in the study in their homes at interview and had cared for seven times as many children in the past, including 66% of all the teens and 83% of all the handicapped children who had been in the 64 homes. These “high providers” functioned like group homes for mentally handicapped individuals. Adapting the group-home concept to foster homes could improve care, especially for children with special needs.
