This article presents an evaluation of an in-home support program for at-risk mothers and their children. The program was multidisciplinary and was focused on development of parenting capacity and child-development competencies. The authors examine issues and problems that resulted from the blending of two models of practice-stabilization/crisis intervention and early intervention/health promotion-and describe the outcome-based evaluation that was used to assess initial and ongoing child development, parent-child interaction, family environment, and social support. When documentation and evaluation of practice and its effect on outcomes proved a considerable challenge, the authors developed a classification system to describe practice in three areas: situations addressed, interventions used, and referrals made. The article describes challenges surrounding program development, implementation, and evaluation.
