Oppositional defiant disorder

Oppositional defiant disorder (ODD) shows up on case exams mostly as a differential: the counselor must decide whether a child's defiance is a stable, cross-setting pattern or something better explained by mood, anxiety, trauma, a learning problem, or conduct disorder.

Criteria at exam depth (paraphrased). A pattern of at least 4 symptoms lasting at least 6 months, shown with at least one person who is not a sibling, drawn from three groups:

• Angry/irritable mood: often loses temper, touchy or easily annoyed, often angry and resentful.
• Argumentative/defiant behavior: argues with authority figures, actively defies or refuses rules, deliberately annoys others, blames others for own mistakes.
• Vindictiveness: spiteful or vindictive at least twice in the past 6 months.

Frequency guide: for children under 5, behavior occurs on most days; from age 5 and up, at least once per week. The behavior causes distress or impairment, does not occur exclusively during a psychotic, substance use, depressive or bipolar disorder, and full criteria for DMDD are not met. Severity by settings: mild = one setting, moderate = at least two, severe = three or more.

Hinge differentials.

• DMDD: persistent irritable mood between severe, frequent outbursts; if DMDD criteria are met, ODD is not diagnosed.
• Conduct disorder: violates others' rights (aggression to people/animals, destruction, theft, serious rule violations); ODD does not. The two can co-occur.
• ADHD: noncompliance from inattention or impulsivity, not deliberate defiance.
• Anxiety or learning disorder: refusal clusters around feared or difficult tasks (e.g., only during literacy blocks), with friendly engagement elsewhere.
• Trauma-related presentations: "defiance" tied to specific reminders, with freezing or shutdown.
• Adjustment or context-specific problems: recent onset or behavior confined to one relationship or home only after a stressor.

On the NCMHCE. Gather collateral (teacher reports, school records) to establish frequency and how many settings are involved. Ask directly about aggression to animals, property destruction, stealing and fire-setting to rule out conduct disorder. Screen for trauma, abuse in the home, and co-occurring ADHD, anxiety, depression and learning problems. First-line treatment is parent management training (consistent praise, clear commands, predictable consequences), plus collaborative problem-solving and school coordination. Consider family stressors and culture when judging what counts as "defiant."

Clinical Pearl: 4 symptoms, 6 months, at least one non-sibling; severity is counted by settings. Persistent irritability between outbursts points to DMDD, which trumps ODD.
