The Validation of C-me
Founded on experience and expertise, C-me is a behaviour profiling tool designed to empower employees and improve business performance


At C-me, we want to ensure our partners and users can trust in, and rely on, the methodology and tools we provide.
Our psychometric principles build upon the psychologist Carl Jung's research into preferences and orientation. His research led to the axis of measurement based on four main behavioural principles of Extraversion, Introversion, Thinking and Feeling. These preference principles are used to underpin the majority of modern psychometric tools.
C-me's aim over the past 10 years has been to make our approach psychologically sound and accessible, memorable and applicable. We have honed our reports to focus on enabling impact through resonance and behavioural action.
C-me has developed Jung's principles into behavioural preference axis and express them through the language of four colours: red, blue, green and yellow. This language provides a recognisable and intuitive way to communicate and engage with individual behavioural preferences.
Constructing the questionnaire
The critical filter behind the initial development was our desire for a system that would lead to real impact, opportunities for personal development and clarity for individuals to understand themselves and others better.
Having developed a questionnaire that feedback showed us consistently measured the preferences of red, green, blue and yellow, we then began testing statements aligned with these amongst hundreds of people. The reports were launched once we reached a high degree of resonance, of over 85%+. That process of resonance assessment has continued over the years with our thousand of users. We continually hone our statements for greater accuracy.
Our model is built around four colours, which measure the aspects of our preferences that drive our behaviour. We measure this through our questionnaire, then the results are aligned with our statement database of over 40,000 statements. These are attributed to individuals by the C-me algorithms to produce your personalised C-me report and other outputs.
We developed the individual questions based on each aspect of behaviour, where any word in isolation could be linked to more than one colour. By grouping words, we are able to build up an accurate picture of different colour 'energies' that an individual may identify with, both consciously and less consciously.

Measuring the Questionnaire
Once we had an accurate questionnaire, we began testing impact amongst varied client cohorts. C-me is unusual in being tested from the outset with representative individuals testing in the context of real team application, rather than test groups who would have self-selected and tested in abstract situations.
Validation of our questionnaire, algorithm and reports never stops. The most important measure for us is face validity, as it is people we work with, which is why we use real people to verify our product. Our profiles provide you with over 85+% accuracy across 7 global languages, based on client feedback scores.
The C-me model
C-me aims to draw out the natural strengths and gifts in people, whilst increasing the understanding that others may differ in how they perceive and approach different circumstances.Providing powerful information for all your people's needs based on Carl Jung's psychology
