Conduct Disorder vs Oppositional Defiant Disorder
“Conduct Disorder vs Oppositional Defiant Disorder” is a question parents ask when daily battles over rules turn into serious aggression or law-breaking. ODD is primarily argumentative, angry, and defiant; Conduct Disorder (CD) adds violation of others’ rights through violence, deceit, or serious rule-breaking. Early, accurate diagnosis and structured treatment improve long-term outcomes for both conditions.
1. Quick Snapshot: ODD vs Conduct Disorder
| Feature | Oppositional Defiant Disorder (ODD) | Conduct Disorder (CD) |
|---|---|---|
| Core issue | Defiance & anger | Violation of rights & rules |
| Typical age | Preschool–primary school | Late childhood–teen years |
| Aggression | Verbal, low-level | Physical, cruel, weapon use |
| Legal trouble | Rare | Common (vandalism, theft) |
| Prognosis | Good with early help | Guarded; needs intensive plan |
Red-Flag Behaviors to Watch
- ODD: Daily arguments, spiteful words, blames others for mistakes.
- CD: Bullying, cruelty to animals, fire-setting, truancy before age 13.
2. What Is Oppositional Defiant Disorder (ODD)?
Diagnostic Criteria (DSM-5)
At least six months of angry/irritable mood plus argumentative/defiant behavior with at least one non-sibling. Symptoms occur in ≥2 settings and cause significant impairment.
Typical Age of Onset
Usually 4–8 years; often noticed soon after child starts school or daycare.
Mild vs Moderate vs Severe ODD
- Mild: Symptoms limited to one setting (e.g., only at home).
- Moderate: Present in ≥2 settings but manageable with support.
- Severe: Three or more settings; frequent outbursts, peer rejection.
3. What Is Conduct Disorder (CD)?
Diagnostic Criteria (DSM-5)
≥3 behaviors in past 12 months (≥1 in past 6 months) across four categories: aggression to people/animals, destruction of property, deceitfulness, serious rule violation.
4 Core Symptom Categories
- Aggression to people & animals
- Destruction of property
- Deceitfulness or theft
- Serious rule violations (truancy, running away)
Childhood-Onset vs Adolescent-Onset
- Childhood-onset: ≥1 criterion before age 10; stronger link to ADHD, poorer prognosis.
- Adolescent-onset: no criteria before 10; often peer-driven, slightly better outcome.
4. Key Similarities Between ODD and CD
- Disruptive Behavior Overlap: tantrums, ignoring adult requests.
- Impact on Family & School: parental stress, teacher complaints, academic gaps.
- Risk of Comorbid ADHD: up to 60% of children with CD or ODD also meet ADHD criteria.
5. Critical Differences: Intent, Severity, & Prognosis
- Control vs. Violation Spectrum: ODD wants control; CD disregards others’ rights.
- Legal Implications of CD: shoplifting, weapon use can create juvenile record.
- Long-Term Outcomes: untreated CD more likely to evolve into antisocial personality; ODD usually stabilizes with therapy.
6. Causes & Risk Factors
Genetics & Neurobiology
Family history of mood or disruptive disorders; low physiological arousal (CD).
Parenting Style & Family Stress
Harsh, inconsistent discipline; parental conflict; exposure to violence.
School & Peer Environment
Large classrooms with low supervision; association with deviant peers.
7. Assessment & Diagnosis at Cadabams CDC
- Comprehensive Psychological Evaluation: clinical interview, IQ, personality tests.
- Family & School Reports: Conners, SDQ, BASC-3.
- Standardized Rating Scales: rule out trauma, mood, ADHD overlaps.
8. Evidence-Based Treatment Plans
Parent Management Training (PMT)
8–12 sessions teaching consistent rewards, time-out, ignoring minor annoyances.
Cognitive Behavioral Therapy (CBT)
Child learns problem-solving, anger coping statements, self-monitoring.
School-Based Interventions
Behavior contract, seating near teacher, daily report card.
