Symptoms of Oppositional Defiant Disorder (ODD) to Assess For

The core symptoms of Oppositional Defiant Disorder include a persistent pattern of angry/irritable mood, argumentative/defiant behavior, or vindictiveness lasting at least 6 months, with symptoms typically emerging by age 8 years. 1

Key Symptom Categories to Assess

1. Angry/Irritable Mood

  • Often loses temper
  • Is often touchy or easily annoyed
  • Is often angry and resentful

2. Argumentative/Defiant Behavior

  • Often argues with authority figures or adults
  • Often actively defies or refuses to comply with requests from authority figures or with rules
  • Often deliberately annoys others
  • Often blames others for his or her mistakes or misbehavior

3. Vindictiveness

  • Has been spiteful or vindictive at least twice within the past 6 months

Assessment Considerations

Duration and Frequency

  • Symptoms must persist for at least 6 months 2
  • Behaviors occur more frequently than typically observed in individuals of comparable age and developmental level 1
  • Document the unrelenting nature of the problem - behaviors are not transient 2

Setting Specificity

  • Determine if behaviors are present in multiple settings or limited to specific contexts 2
  • Commonly, a child may be difficult with parents but compliant in school and with other adult figures 2
  • Severity classification (mild, moderate, or severe) is based on the number of settings in which symptoms are present 1

Functional Analysis

  • Identify antecedents and consequences of the child's behavior 2
  • Assess parent and others' behaviors that may reinforce problematic behaviors 2
  • Evaluate if parents unwittingly reinforce oppositional behavior (e.g., completing tasks assigned to child, giving in to demands) 2

Distinguishing Features

Differentiate from Normal Development

  • Isolated occurrences of oppositional behavior with preserved functioning in most domains suggest normative behavior rather than ODD 2
  • Consider if behaviors are reactions to peer conflicts or significant stressors 2

Differentiate from Other Disorders

  • Distinguish ODD from:
    • Simple adjustment reactions
    • Conduct Disorder (CD) - ODD involves minor, often verbal aggression rather than the more severe physical forms in CD 2
    • Intermittent Explosive Disorder (IED) - episodic explosive outbursts suggest IED 1

Assessment Methods

Multi-Informant Approach

  • Obtain information directly from the child and parents 2
  • Include reports from teachers, daycare providers, and other school professionals 2
  • Be aware that agreement between informants is often low 2
  • Teachers and parents tend to agree more with each other about externalizing behaviors than with the child 2

Standardized Assessment Tools

  • Use specific questionnaires and rating scales to evaluate ODD and track progress 2
  • These can help distinguish ODD from normative oppositionality 1

Comorbidity Assessment

Common Comorbidities to Screen For

  • ADHD (present in approximately 14% of ODD cases) 1
  • Anxiety disorders (14%) 1
  • Depressive disorders (9%) 1
  • Learning disabilities and language disorders 1
  • Chronic pediatric illness (often associated with increased disruptive behavior) 2

Impact of Comorbidities

  • When ODD and ADHD co-occur, children tend to show more aggression, greater range of problem behaviors, and higher peer rejection 1
  • ODD with comorbid CD shows higher rates of mood disorders and social impairment 1
  • Treating comorbid conditions often improves ODD symptoms 3

Additional Assessment Areas

Bullying Involvement

  • Assess the child's involvement in bullying as either victim or perpetrator 2
  • This can indicate impaired functioning and risk for aggression or violence 2

Access to Weapons

  • Evaluate children's access to weapons and supervision of such 2

Environmental Factors

  • Explore if oppositionality is triggered by physical abuse, sexual abuse, or neglect 2
  • Consider if child becomes oppositional in response to excessive or unrealistic parental demands 2

Prognostic Considerations

  • Approximately 30% of children with ODD progress to conduct disorder 1
  • About 10% may eventually develop antisocial personality disorder 1
  • Adults and adolescents with ODD history have >90% chance of being diagnosed with another mental illness in their lifetime 3
