This chapter examines three common childhood disorders (conduct disorders, anxiety disorders, and depressive disorders) using the Intersectionality/Resiliency Formation framework, with special attention to important developmental processes at play. It focuses on two specific disruptive disorders, oppositional defiant disorder and conduct disorder because these disruptive behavior disorders are more likely to arouse negative reactivity in persons in child's environment and also pull mental health professionals toward a negative focus on pathology. These two disorders are seen in mental health and community clinics more than any other disorders in minors, are often co-occurring with other psychiatric disorders, and may be complicated by substance abuse and severely delinquent behavior. As externalizing disorders, they are visible to observers and disruptive in the child's environment, whereas externalizing disorders are often less salient to caregivers, teachers, and peers. The chapter focuses on diagnostic developmental considerations when evaluating these and other common disorders in children and adolescents.
