This study examined whether parent reports of their child's service use are more reliable in a family-focused delivery system than in more typical service environments. Data were obtained through the Fort Bragg Evaluation Project, a longitudinal assessment of a managed care model for delivering mental health services to children and adolescents. Analysis is based on about 600 youth, of whom about 60 percent received services through the family-focused demonstration program and 40 percent through two traditional systems of care. Utilization data were obtained from both the youth's primary caretaker and institutional records. Analysis indicated that parents in the demonstration and comparison groups tended to report roughly equivalent rates of service use as found in their institutional records. Also, high percentages of agreement between parent and institutional reports were found for all service types, in both service systems. Analysis of reliability of reports found higher specificity and lower sensitivity for both demonstration and comparison groups. (Contains 19 references and endnotes.) (DB)
