Abstract
Disruptive behavior and dissocial disorders, along with attention deficit hyperactivity disorder (ADHD), are among the most common and impairing psychological conditions in children and adolescents. Clinicians and researchers increasingly recognize these conditions as relevant across the life span, with great heterogeneity in presentation, variation across settings and informant perspectives, and links to other important clinical and functional concerns. Taxonomically, oppositional defiant disorder and conduct-dissocial disorder comprise the two major disorder categories in the disruptive behavior and dissocial disorders grouping of 11th revision of the International Classification of Diseases, whereas ADHD is an important category in the neurodevelopmental disorders grouping. This chapter provides the elements of a psychological approach, including psychological models and recommendations for psychological assessment for disruptive behavior and dissocial disorders and ADHD. It discusses presentations and symptom patterns, specifiers and subtypes, boundaries with normality, differential diagnoses, co-occurring disorders, developmental course, cultural and contextual considerations, and gender-related features.
