Internationally recognized for its scope and imagination for over six decades, Psychiatry has been restructured in response to rapid research advances in psychiatry, psychology, neuroscience, group and family processes, and other disciplines that investigate mental health. Increasingly, studies in these areas are being placed in the context of human development across the lifespan, and linked to carefully studied variations in the social ecology of human life. This journal is an essential resource for researchers, clinicians, and trainees seeking broadly applicable and effective solutions to the major unsolved problems in the field.
