Disorders Included

  • Oppositional Defiant Disorder

  • Intermittent Explosive Disorder

  • Conduct Disorder

1. Oppositional Defiant Disorder (ODD)

Clinical Description

A disorder characterized by a persistent pattern of angry/irritable mood, argumentative or defiant behavior, and vindictiveness toward authority figures.
Symptoms usually emerge during childhood and occur in interactions with parents, teachers, or other authority figures.

Behavior is typically less severe than conduct disorder, as it does not involve serious violations of others’ rights.

Diagnostic Features

DSM-5-TR identifies three symptom domains:

1. Angry/Irritable Mood

  • Often loses temper

  • Easily annoyed

  • Frequently angry or resentful

2. Argumentative/Defiant Behavior

  • Actively defies rules

  • Deliberately annoys others

  • Blames others for mistakes

3. Vindictiveness

  • Spiteful or vindictive behavior occurring at least twice within 6 months

Duration requirement:

  • Symptoms must persist at least 6 months.

Prevalence / Statistics

  • Prevalence estimated 3–10% of children.

  • More common in boys before adolescence.

  • Symptoms often begin during preschool or early school years.

Differential Diagnosis

Must be distinguished from:

  • Conduct Disorder

  • Attention-Deficit/Hyperactivity Disorder

  • Disruptive Mood Dysregulation Disorder

Key distinction:
ODD involves defiance and hostility, but does not involve severe aggression or criminal acts.

Assessment Tools

Common assessment methods include:

  • Clinical interview

  • Behavior rating scales (teacher and parent reports)

  • Child Behavior Checklist (CBCL)

Prognosis

Untreated ODD may progress to:

Environmental

  • Family conflict

  • Antisocial Personality Disorder

Treatment

Psychological Treatments

Key difference:
IED involves impulsive aggression rather than persistent rule violation.

Assessment Tools

  • Clinical interviews

  • Aggression assessment scales

  • Behavioral history evaluation

Causes / Risk Factors

Biological

Assessment Tools

  • Clinical interviews
