Core diagnostic criteria, specifiers, differential considerations, and documentation support in one open, scan-friendly view.
All criteria are shown. No expand controls or hidden sections.
Core criterion A
≥4 symptoms from: angry/irritable mood (loses temper; touchy/easily annoyed; angry/resentful); argumentative/defiant behaviour (argues with authority; defies rules; deliberately annoys; blames others); or vindictiveness — for ≥6 months, exhibited during interaction with ≥1 non-sibling individual
Core criterion B
Causes distress in individual or others in their immediate social context, or negatively impacts functioning
Core criterion C
Not better explained by another mental disorder (psychotic, mood, SUD, DMDD, or conduct disorder)
Consistent with [Oppositional Defiant Disorder] [specifier(s)]. For at least six months, there has been a recurrent pattern of angry or irritable mood including frequent temper loss; being easily annoyed; persistent anger or resentment; argumentative or defiant behaviour including frequent arguing with authority figures; active defiance or refusal to comply with rules or requests; deliberate annoyance of others; blaming others for mistakes or misbehaviour; and vindictiveness, with at least four of the above symptoms present, occurring during interaction with at least one individual who is not a sibling. The presentation is further characterised by symptoms that are persistent rather than episodic. These features have resulted in clinically significant distress in the individual or others in their immediate social context, or impairment in social, educational, or occupational functioning, and the behaviours are not occurring exclusively during the course of a psychotic, substance-related, depressive, or bipolar disorder.
