Deconstructing oppositional defiant disorder: clinic-based evidence for an anger/irritability phenotype

Area of Science:

• Child and Adolescent Psychiatry
• Developmental Psychology
• Behavioral Science

Background:

• Oppositional defiant disorder (ODD) is a common childhood behavioral disorder.
• Anger/irritability symptoms (AIS) are a key diagnostic feature of ODD.
• Understanding the correlates of AIS is crucial for effective intervention.

Purpose of the Study:

• To investigate risk factors and co-occurring symptoms associated with mother-reported versus teacher-reported AIS in ODD.
• To compare youth with AIS to those with noncompliant ODD symptoms (NS) and clinic controls.

Main Methods:

• A clinic-based sample of 1,160 youth aged 6-18 years was assessed.
• Mothers and teachers completed background history and symptom checklists (DSM-IV).
• Youth meeting AIS criteria were compared to NS ODD youth and clinic controls.

Main Results:

• Youth with AIS exhibited higher anxiety, mood, and conduct disorder symptoms compared to NS youth.
• Informant (mother vs. teacher) and youth age influenced observed symptom differences.
• Developmental, psychosocial, and psychiatric correlates varied based on informant and age.

Conclusions:

• AIS may represent a more severe and distinct clinical phenotype of ODD.
• The reporting source (informant) and the child's age are critical factors in assessing ODD.
• Further research is needed to clarify the clinical implications of informant and age variations.
