Oppositional Defiant Disorder

Medically reviewed · Ratel Health editorial team · Sunday, 16 August 2026

A childhood-onset condition involving a persistent pattern of angry or irritable mood, argumentative or defiant behavior, or vindictiveness toward authority figures.

Overview

Oppositional defiant disorder involves a persistent pattern of angry or irritable mood, argumentative or defiant behavior, or vindictiveness lasting at least six months, directed primarily toward authority figures.

Signs and Symptoms

Symptoms can include frequent temper loss, arguing with adults, actively defying rules, deliberately annoying others, and blaming others for one’s own mistakes. Experiencing one or more of these symptoms does not necessarily mean that a person has this condition. Diagnosis requires an appropriate clinical evaluation.

Causes and Risk Factors

The exact cause is not fully understood. Temperament, inconsistent parenting environments, and family or genetic factors are each associated with risk.

Diagnosis

A diagnosis should be made by a qualified healthcare professional following a comprehensive clinical assessment. Clinicians may use established diagnostic frameworks such as DSM-5-TR and/or ICD-11 as part of a comprehensive assessment.

Treatment

Treatment depends on the individual’s symptoms, clinical history, severity, age, co-occurring conditions, and other relevant factors.

Psychotherapy

Parent management training and family-based behavioral interventions have strong evidence supporting their use.

Living With Oppositional Defiant Disorder

Consistent, predictable routines and positive-reinforcement-based parenting strategies can help reduce conflict.

When to Seek Professional Help

Professional evaluation may be appropriate if symptoms persist, worsen, cause significant distress, or interfere with work, school, or relationships.

Emergency Situations

If a person may be in immediate danger, is experiencing a medical or psychiatric emergency, or may harm themselves or another person, seek immediate assistance through appropriate local emergency services.

Outlook

Many children improve substantially with early behavioral intervention and family support.
