In conjunction with the national survey of mental health service organizations (Schoenwald et al. this issue), a separate but complementary national survey was conducted of family advocacy, support and education organizations (FASEOs). Directors of FASEOs within the same localities as the mental health agencies responded to a survey and provided information in four areas: (1) structure and funding; (2) factors influencing advocacy decisions about children's mental health; (3) types of services provided by FASEOs and factors perceived as related to improved outcomes; and (4) the types of working relationships between FASEOs and local mental health clinics. Findings from a total of 226 (82% response rate) portray a network of family advocacy, support and education organizations that are strategically poised to effect substantive change and characterized by significant fiscal instability. Results from this survey and implications for delivery of family-based services are provided.
