Recent work on emotional regulation gives a powerful new lens through which to view the evolution across childhood and adolescence of the lived experience and clinical presentation of depression. We have a richer picture of the depressed child, and the child at risk for depression, in interaction with family and wider world. We know more about the development and the developmental psychopathology of coping strategies. These advances give provocative clues to the actual processes whereby well-established risk and protective factors might interact to produce, sustain or curtail a depressive syndrome. This in turn opens the door to treatment and prevention approaches that are truly developmentally informed. This is the philosophy behind this completely updated and comprehensive analysis of childhood depression.

This publication promotes school based mental health services as a means for increasing access to care and for early intervention. There are 3 levels of intervention in school-based mental health: 1. Universal promotion/prevention: Implementing whole-school approaches (including training teachers and administrators) to ensure and foster wellness. 2. Targeted prevention: Providing prevention services for youth at-risk of developing mental health problems. 3. Indicated services: Providing assessment and direct care for youth with identified mental health needs. The approach of this Issue presents current evidence-based practice in schools and review of schools as a vital part of systems of care for youth. In addition to psychiatrists, this issue addresses collaboration with families, educators, administrators, social workers, counselors and psychologists. The Editors leading this issue are from Vanderbilt University and University of Maryland. Both Vanderbilt and Maryland have well-established clinical programs that provide a full continuum of mental health services, including "indicated services" to serve youth with mental health diagnoses (i.e., severe psychiatric disorders). Psychiatrists are part of the treatment team, and work directly in the school or provide consultation (often via telehealth technologies). Given that family engagement is a major part of making therapies work effectively, partnering with families is a critical part of the treatment process.

Schools can play an important role in addressing the unmet mental health needs of youth by potentially increasing access to care in a cost-effective manner. This venue provides unparalleled access to youth and exemplifies a single setting through which the majority of children can be reached. This very timely issue provides a much-needed analysis of the types of situations in which schools can and must address the mental health needs of their students, and the methodology for doing so. With an eye towards current technologies (articles cover telepsychiatry and web-based interventions), authors review school-based interventions for students suffering from post-traumatic stress-syndrome, generalized anxiety, social anxiety, depression, ADHD, psychoses, substance abuse, and other disorders. Of special interest are the articles covering bullying (including internet bullying) and mobilizing a crisis team after student death.
