Objectives: To explore perceptions related to increased utilization of group interventions as a part of the service reorganization within a pediatric rehabilitation program. Methods: Individual interviews with program administrators (n = 13) and focus groups with therapists (n = 19) and parents of children with disabilities (n = 5) were conducted. Data were analyzed using a coding grid inspired by the organized action systems theory. Results: Administrators and therapists identified several issues including the need to improve the referral process for groups and the coordination across services. Groups considerably modified practice and required substantial efforts from therapists. Administrators felt groups contributed to increased service accessibility. Although therapists had some doubts about service quality in groups, especially in regard to the reduced attention to individual needs, they reported positive benefits on children's social participation. Generally, parents were satisfied with group interventions. Conclusion: Groups appear to be a promising method of service delivery, but organizational-related issues should be considered.
