Which disorder is described by persistent anger/irritability and defiant behavior toward authority figures?

• A. Autism Spectrum Disorder
• B. Oppositional Defiant Disorder
• C. Generalized Anxiety Disorder
• D. Conduct Disorder

Answer: (B)

The behavior pattern being tested is a persistent pattern of angry or irritable mood and frequent defiance toward authority figures. This combination is characteristic of Oppositional Defiant Disorder. Children with this condition typically show ongoing temper loss, arguing with adults, deliberately defying requests or rules, blaming others for their own mistakes, being easily annoyed, and sometimes spiteful or vindictive. These behaviors must last for a notable period (usually at least six months) and cause clear problems at home, school, or with peers.

This fits better than autism, which centers on social communication difficulties and restricted interests; generalized anxiety disorder, which involves pervasive worry and physical symptoms rather than a defiant stance toward authority; and conduct disorder, which involves more serious violations of others' rights (like aggression toward people or animals, property destruction, or theft). When the hallmark is persistent anger and defiance toward authority without the more severe rights-violating behaviors, Oppositional Defiant Disorder is the best fit.
