In early childhood it is diagnosed cautiously, requires an enduring pervasive pattern beyond developmental expectation, and must be differentiated from ODD, ADHD, language disorder and trauma.","answer_md":"*A young child with conduct concerns is more often signalling unmet developmental need than \"defiance\" — and the distinction matters clinically.*\n\n## In short\nConduct-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.\n\n## The ICD-11 picture in early childhood\nIn preschool and early-school children, features cluster as:\n- **Aggression** to people or animals — frequent severe tantrums, hitting, biting, cruelty disproportionate to context\n- **Destructiveness** — deliberate breaking of property\n- **Deceit or theft** beyond age-typical fibbing\n- **Serious norm violation** — persistent defiance and rule-breaking across settings (home *and* nursery)\n\nICD-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.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an online tool. We profile the child's [conduct-dissocial presentation](/conduct-dissocial-disorder) alongside language, attention and regulation through [behavioural therapy](/behavioural-therapy) and a structured [clinician-administered assessment](/ask/what-is-the-abilityscore-and-how-is-it-calculated).\n\n## Trusted sources\nWHO ICD-11 Mortality and Morbidity Statistics, category 6C91; WHO ICF framework for functioning-based formulation.\n\n**Next step —** Refer early-childhood conduct concerns for structured developmental assessment rather than behavioural management alone — [partner with a Pinnacle centre](/conduct-dissocial-disorder).\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/what-is-conduct-dissocial-disorder-and-what-are-its-icd-11-features-in-early-childhood","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU
