Reflecting the latest advancements in the field and complete DSM–5 criteria, Robert Weis’ Introduction to Abnormal Child and Adolescent Psychology provides students with a comprehensive and practical introduction to child psychopathology. The book uses a developmental psychopathology approach to explore the emergence of disorders over time, describe the risks and protective factors that influence developmental processes and trajectories, and examine child psychopathology in relation to typical development and children’s sociocultural context. The fully revised Fourth Edition includes a new chapter on research methods, a greater emphasis on the ways social-cultural factors affect each disorder covered, and recent research findings on topics such as autism spectrum disorder and adolescents’ use of nicotine and marijuana vaping products.
