This volume examines the use of prediagnostic mental health screening as part of preventive services in primary and secondary schools. It presents the theory underlying mental health screening for children and the obstacles against its widespread implementation. Empirical findings illustrate the potential of schools as the platform for mental and general health services. The authors contribute their own experiences to provide real-world perspectives and establish future directions for research and practice on mental health screening in schools. Featured topics include: Rationales for comprehensive mental health screening in schools. Evaluations of widely used assessment instruments for suitability with children and youth. An analysis of mental health screening in a Response to Intervention framework. The multiple-gate approach to screening and service delivery. Benefits and challenges of screening in educational settings. Current and emerging issues in the field. Mental Health Screening at School is a valuable resource for clinicians and scientist-practitioners, researchers, and graduate students in school psychology, social work, special education, and school counseling, as well as school principals and administrators.
