Behavioral, Social, and Emotional Assessment of Children and Adolescents is a comprehensive textbook that provides a scientific and practical framework for assessing children's and adolescents' behavioural, emotional, and social functioning. Widely used in school psychology, clinical psychology, counselling, and special education, the book emphasizes evidence-based, culturally responsive, and ecologically valid assessment practices. The text explains the complete assessment process, including behavioural observation, behaviour rating scales, clinical interviewing, sociometric methods, self-report instruments, and projective techniques. It discusses assessment of externalizing behaviours, internalizing disorders, social skills, peer relationships, autism spectrum disorders, and culturally diverse populations. The fourth edition also incorporates assessment within the Response to Intervention (RTI) framework and highlights strengths-based assessment by considering resilience, coping skills, empathy, and problem-solving abilities alongside behavioural concerns. Designed for graduate students and professionals in psychology, education, counselling, psychiatry, and social work, the book integrates current research with practical guidance for conducting comprehensive psychological assessments that support effective intervention planning and educational decision-making.
