"Data Trends" reports present summaries of research on mental health services for children and adolescents and their families. The article summarized in this "Data Trends" reports research that revealed mental health consultation has positive impact on teacher and center quality. Research has shown that parents of children, aged one to three years, are less likely to seek and receive professional help if their child has behavioral problems, in comparison to other developmental concerns. In early childhood settings, staff are increasingly concerned about a growing percentage of young children exhibiting behavioral and emotional difficulties. One way that mental health professionals can reach children, families, and early childhood teachers is through mental health consultation services in early childhood settings. The aim of consultation is to "increase the ability of staff, families, programs, and systems to prevent, identify, treat and reduce the impact of mental health problems among young children in mental health settings." The authors of this article report an evaluation of the Early Childhood Mental Health Initiative (ECMHI) that supported mental health consultation in a variety of low-income, ethnically diverse day care and preschool centers in San Francisco, California.
