When online harm reaches the children you work with, you need more than guidance documents. You need the person who wrote the theory.

I'm Dr Catherine Knibbs, Consultant Child & Adult Trauma Psychotherapist, cyberpsychologist, and developer of CYBERTRAUMA™ theory. I help organisations and professionals understand what online harm does to humans, and what to do about it.

Online harm is the issue. Cybertrauma is the impact.

I named it, defined it, and built the clinical framework for recognising it. Read the definition and the method →

Free assessments

Find out where you stand, in five minutes

Two assessments built on the five pillars of the CYBERTRAUMA™ Recognition System, one for you as a practitioner, one for your organisation. Both are genuinely free and give you your result on screen straight away.

For practitioners

How ready are you for the next disclosure?

Twenty questions, under five minutes. A score across five areas and a plain read on where the gaps are. Most people score lower than they expect on recording and escalation, and that is the point. It was never taught.

Take the Recognition Readiness Scorecard Free · 20 questions · no judgement in it

For organisations

Where does your organisation actually stand?

Ten questions, under five minutes. A named profile, from Reactive Response through to Evidence-Ready, showing how your setting would handle a disclosure today, and what an inspector would find if they asked tomorrow.

Take the Organisation assessment Free · 10 questions · for schools, trusts, LAs and safeguarding teams
