Conduct-Dissocial Disorder: AbilityScore 400–500 — what next?

An AbilityScore in the 400–500 band is not a verdict — it's a starting line, and a clear plan can change the road ahead.

In short

Your child's AbilityScore in the 400–500 band gives your clinician a structured baseline of where your child is right now across behaviour, emotional regulation and daily functioning — measured against your child's own profile, not against other children. The next step is simple and hopeful: turn that measurement into a personalised plan with your Pinnacle clinician, and begin consistent therapy that builds the skills underneath the behaviour. A score in this band describes a stage to grow from, never a ceiling.

What this band means for your child

Conduct-Dissocial Disorder (ICD-11 6C91) describes a persistent pattern of behaviour that breaks age-appropriate social rules — but underneath that behaviour are skills that can be taught and strengthened: managing big feelings, reading social cues, pausing before acting, and repairing relationships. A 400–500 baseline simply tells your clinician which of these supports to prioritise first, and how intensively.

• Behaviour is communication. Aggression or rule-breaking is often the visible tip of frustration, anxiety or unmet need underneath.
• The family is part of the plan. The strongest evidence for conduct difficulties supports parent-and-family approaches alongside the child's own work — calm, consistent routines and warm limits at home multiply the gains made in session.
• Progress is re-measured, not guessed. Your child is reassessed against this same baseline so you can see movement clearly.

Your next steps

1. Convert the score into a plan — sit with your Pinnacle clinician to translate the 400–500 band into specific, prioritised goals.
2. Begin consistent behavioural therapy — regular sessions that build self-regulation and social skills, with strategies you can carry into home and school.
3. Loop in school and home — shared, predictable expectations across settings make change stick.
4. Watch for safety flags — if there is risk of harm to your child or others, talk to your clinician promptly so the plan can be adjusted.

The Pinnacle way

Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under the care of a qualified clinician — never from an online form or a number alone. Drawing on 2.5 billion+ data points and 25 million+ therapy sessions, your clinician personalises the path for your child and re-measures against their own baseline, so progress is visible and honest.
