This article describes one component of a comprehensive model of family-centered preventive mental health services that were delivered as part of a University-Head Start Partnership grant. Personal Best, a carefully designed role competence curriculum, was implemented through a group intervention to examine the personal and contextual factors that impact parenting and maternal self-efficacy. Qualitative methods were used to evaluate the implementation process and the perceived impact of the intervention. Three key themes emerged: friendship and women's issues, information and mutual support, and personal growth. The findings, implications, and recommendations for continued development of child and family mental health services are discussed. (Contains 1 figure, 2 tables, and 1 footnote.)
