Exchanging Glances? Systems, Practice, and Evidence in Children's Mental Health Services

Systems of care and evidence-based practice possess distinct histories. Though each developed out of attempts to improve services to youth with emotional and behavioral disorders, they did so from perspectives so different as to appear diametrically opposed. Service systems exist at multiple levels, including the practice, program, and system levels (Rosenblatt, 1988, 2005; Rosenblatt & Woodbridge, 2003). Research on health and mental health service systems similarly varies, often by level of the service system, with the research methods, independent and dependent variables, populations of interest, and ultimately the consumers of the research product interacting differentially in the creation and understanding of what constitutes a knowledge base for service delivery. Systems of care and, with limited exceptions, evidence-based practices exist at different levels of the service delivery structure, require and derive from different research approaches, and speak to overlapping but historically different audiences.
