Differentiate internalizing and externalizing behavior problems.

• A. Internalizing problems involve internal distress; Externalizing problems involve outward behaviors
• B. Internalizing problems involve outward behaviors; Externalizing problems involve inward distress
• C. Internalizing problems involve withdrawal; Externalizing problems involve aggression
• D. Internalizing problems involve social engagement; Externalizing problems involve compliance

Answer: (A)

The main idea here is how each type expresses problems: internalizing problems are directed inward, while externalizing problems are directed outward. Internalizing problems involve internal distress such as persistent sadness, anxiety, or social withdrawal, and may include somatic symptoms. Externalizing problems show up as outward, observable behaviors like aggression, defiance, rule-breaking, or hyperactivity. This distinction makes the statement that internalizing problems involve internal distress and externalizing problems involve outward behaviors the best fit. The other descriptions either flip the directions or focus only on a narrow symptom (like withdrawal or aggression) without capturing the broader pattern of inward vs. outward expression.
