Conduct-Dissocial Disorder (ICD-11 6C91): Early-Childhood Features

A young child with conduct concerns is more often signalling unmet developmental need than "defiance" — and the distinction matters clinically.

In short

Conduct-Dissocial Disorder (ICD-11 6C91) is characterised by a repetitive, persistent pattern of behaviour that violates the basic rights of others or major age-appropriate societal norms — aggression, destructiveness, deceitfulness, serious rule-breaking — sustained over time and beyond ordinary childhood mischief. In early childhood the diagnosis is applied cautiously: many presentations reflect developmental, language, attentional or regulatory difficulties rather than an entrenched conduct pattern.

The ICD-11 picture in early childhood

In preschool and early-school children, features cluster as:

• Aggression to people or animals — frequent severe tantrums, hitting, biting, cruelty disproportionate to context
• Destructiveness — deliberate breaking of property
• Deceit or theft beyond age-typical fibbing
• Serious norm violation — persistent defiance and rule-breaking across settings (home and nursery)

ICD-11 requires the pattern to be enduring (commonly ~12 months), pervasive across contexts, and clearly beyond developmental expectation — not a single phase or reaction to acute stress. Differentiate from Oppositional Defiant Disorder (6C90), ADHD, language disorder, trauma and intellectual disability, which frequently co-occur and shape presentation. The limited prosocial emotions qualifier flags a higher-risk subgroup.

The Pinnacle way

A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online tool. We profile the child's conduct-dissocial presentation alongside language, attention and regulation through behavioural therapy and a structured clinician-administered assessment.
