The beginning chapters thoroughly describe normal development, citing Freud, Piaget, and Kohlberg. They discuss developmental assessment, addressing standardized intelligence tests, developmental screens, parental reports, neurodevelopmental evaluation, and differential diagnosis. The comprehensive developmental and behavioral disorders sections provide information in a consistent format: definition, prevalence, etiology and clinical features, management, and prevention. Tables and algorithms are included for differential diagnosis, treatment approaches, drug dosage, and criteria for referral to educational, social services, and medical specialists.
