Early intervention (EI) for children with physical disabilities is advocated as a means of enhancing child outcomes and family functioning. The issues confronted by service providers in delivering this support have received relatively little attention. The purpose of this study was to gain an understanding of the experiences of frontline EI staff delivering services to children with physical disabilities and their families. Researchers sought views about the ways in which EI programs provide services, how programs build and maintain relationships with families and team members, the prevalence of changing and unmet family needs, the presence of barriers to optimal service delivery, and recommendations for service improvement. Qualitative interviews with 10 staff members highlighted both positive aspects of service quality and issues encountered in the provision of services. Staff commented favorably on family-centered practice; aspects of service structure/delivery, including offering a wide range of supports, flexible service provision, and the focus on intervening early; and provider-related aspects including teamwork and interagency coordination and appropriate personal qualities and skills. Despite the strong endorsement of EI, participants also identified several challenges: meeting the high demand for services, under and unmet needs, and inadequate funding and staffing.
