Summer camps are commonly implemented as a psychosocial intervention for children with chronic illnesses; however, there have been few published consumer (parent and child) satisfaction evaluations of summer camps. Such evaluations are important both for improving existing services for children and families, as well as to build an empirical understanding of camp interventions. To illustrate the use of a program evaluation methodology within the context of a chronic illness summer camp, a program evaluation was conducted of a camp for children with cancer and their siblings. Results from the evaluation indicated that parents and children were highly satisfied with the camp experience, ranging from the food, staff, facilities, to campers' activities. Campers reported that the recreation opportunities, peer support, and respite from their lives at home were reasons they appreciated the camp experience. Parents reported that peer support for their children, respite for themselves and their children, and improvements to their child's behaviors and level of independence were helpful features of the camp experience.
