This book describes research that sought to clarify if the professional practice of educational/school psychologists is evidence-based when recommending interventions for disruptive adolescents who are diagnosed as seriously emotionally disturbed. Two lines of investigation were employed. First, a literature search using three distinct methodologies - a systematic literature review, a meta-analysis of studies and a best evidence synthesis. Second, a survey of a large sample of school psychologists. All aspects of the literature search confirmed that the current research on effective treatments for seriously emotionally disturbed adolescents is extremely limited.


“Overall this draft provides much needed data and discussion in an area of educational provision where too much is taken for granted. In particular the focus on the role and work of educational psychologist in relation to young people with ‘severe emotional disturbance’ is one which is long overdue and about which little has been written. – Dr. John Visser, University of Birmingham
