Conduct disorder in childhood and adolescence is considered to be a significant mental health concern because of its connection to numerous other social, emotional, and academic outcomes, both in terms of concurrent and future functioning. This chapter focuses on the examination and explanation of the treatment strategies for the conduct disorder. There are four main groupings of behavior for conduct disorder: aggressive conduct, nonaggressive conduct, deceitfulness or theft, and serious rule violations. The chapter examines the role of genetic, neurological, and environmental factors implicated in the development of conduct disorder. Psychosocial treatment programs such as multisystemic therapy (MST), functional family therapy (FFT), and multidimensional treatment foster care that combine parental management training (PMT), structural family therapies, and skill-building appear to have a moderate to large-effect size in reducing aggression and symptoms of conduct disorder.
