'This well-balanced presentation of the empirical science and clinical practice of child psychopathology is much needed. Dr Schneider and colleagues present very readable, seamlessly clear explanations of complex concepts at a sophisticated yet accessible level. The material is very up to date, with balanced, sophisticated coverage of fundamental developmental psychopathological processes. The writing is entertainingly precise, the views refreshingly constructive, and basic concepts are presented in a stimulating and readable way.' Anna Beth Doyle, Distinguished Professor Emeritus of Psychology, Concordia University, Montréal
