From the very inception of Smart Support and throughout its first four years, a rigorous and comprehensive external evaluation was integrated into the program. By establishing a close partnership and following Community Based Participatory Research (CBPR) principles, Smart Support program leaders and the Indigo Cultural Center evaluation team pursued the following evaluation goals: 1. To determine whether Smart Support is meeting its stated objective; 2. To inform the program's ongoing design and implementation; 3. To contribute to the literature on effective strategies for infant and early childhood mental health consultation; and 4. To provide findings that could guide Arizona and national efforts to build a comprehensive system of quality enhancement initiatives for the entire continuum of child care providers. (author abstract)
