Since the 2003 release of the third edition of Concise Guide to Child and Adolescent Psychiatry, research on mental illness in children and the practical applications of this research have been evolving at a rapid pace. With these changes have come enhanced methods of assessment and treatment. Topics covered in this text include: The use of DSM-IV-TR for diagnosing psychiatric disorders in children and ways in which adult criteria can be adapted for use in young patients. An outline of the Axis I conditions especially relevant to children and adolescents that may be a focus of clinical attention. A review of how childhood psychological disorders often occur in combinations and require broad-spectrum rating scales to supplement the diagnostic process and help avoid overly narrow focus on the presenting problem. New trends in treatment that include a consideration of biological factors, multimodal treatment approaches, multidisciplinary teams, and use of evidence-based interventions. Ways to help both the patient and the parent or caregiver through the treatment process for better outcomes. Identification of the strengths and vulnerabilities that are critical to treatment plans, such as the family's financial resources and the child's social environment, which includes school, neighborhood, and social support networks, all of which influence the choice of treatment strategy. Concise Guide to Child and Adolescent Psychiatry provides professionals in psychiatric settings, pediatric offices and hospitals, schools, and juvenile justice settings with an efficient and easily portable reference to pediatric mental health topics of concern to practicing clinicians and students alike. Designed to fit into a lab coat or jacket pocket, this manual offers the information that most experts agree is relevant to helping children and adolescents overcome mental disorders.
