• A. Anxiety disorder
• B. Disruptive disorder
• C. Mood disorder
• D. Substance use disorder

Answer: (B)

Disruptive behavior problems are the most common among children and adolescents in the child welfare system. In a large synthesis of many studies, externalizing disorders like oppositional defiant disorder and conduct disorder show the highest rates in this population. This pattern makes sense because these behaviors are more observable in daily settings—home, school, and caregiving environments—so they are more likely to be identified and documented in welfare contexts. Trauma, instability, and chronic stress common in maltreated youths often manifest as outward, rule-breaking, or aggressive behaviors, which drives higher reported prevalence of disruptive disorders compared with internalizing issues like anxiety or mood disorders. Substance use tends to rise with age and specific risk pathways, so it’s not as consistently prevalent across all ages in welfare samples.
