This conference paper discusses the results of a study that investigated the validity of the Family-Centered Behavior Scale (FCBS) and its companion tool, the FCBS-Importance. On the FCBS, parents of children with special needs rate how often a professional with whom they work performs certain family-centered behaviors. On the FCBS-Importance, parents rate the importance of each of these behaviors. The study surveyed a total of 443 parents/caregivers of 406 children with special needs. Evidence of scale validity was found in three analyses: the ability of the scale to differentiate between "best" and "worst" staff members, correlations between scale items and satisfaction with staff members, and importance rating of respondents. The three most highly-rated importance items pertained to the staff member listening to the family, treating the family with respect, and accepting the family as important team members. For caregivers of children with emotional/behavioral problems, five behaviors were rated significantly higher in importance, including getting the family services from other agencies; getting help from family, friends, and community; providing information; caring about the entire family; and accepting the family as important team members.
