Family-centered practice (care, intervention, services, or help giving) and family-focused, and family-based care are terms used interchangeably over the past 60 years to describe an approach to working with children with disabilities and their families. Common beliefs fundamental to the implementation of a program that incorporates family-centered practice include: (1) the family is a key member of the team and is constant in the child's life; (2) when one helps the child he or she also helps the family; (3) the family must be treated with dignity and respect; (4) the family and professional have a shared responsibility to work as collaborative partners in the development of outcomes and implementation of the service plan, within the context of the family's life; and (5) the family needs and priorities help direct the service plan and intervention. These beliefs regarding family-centered practice have influenced the design and implementation of services for children with disabilities and their families in health care, early childhood, and educational programs. As programs implement family-centered practices, service providers shift from focusing on the child to considering the needs of the whole family. No matter what type of program providers work in, if they understand the activities families are able to do successfully as well as those activities which are challenging, providers can work collaboratively with families to identify family priorities and implement supports to achieve desired outcomes. Providers, however, need to identify ways of measuring family outcomes if they believe family outcomes are an essential part of the services being provided. In this article, the author urges the readers to try using the Life Participation for Parents (LPP), a new instrument which asks family members caring for a child with a disability to rate their ability to engage in activities and consider their efficiency (quantity) and effectiveness (quality) of participating in the activities using a Likert scale. Each question also allows written comments related to the question. The scale and comments can then form a basis for discussion between the family and provider to identify if a new outcome is needed and develop intervention strategies to achieve the outcome.
