Everything DiSC is a simple yet effective tool that measures an individuals preferences and tendencies based on the DiSC ® model.
It describes four basic behavioural styles: D, i, S, and C:
D (Dominance) style is active and questioning.
This describes people who are direct, forceful, and outspoken with their opinions.
i (Influence) style is active and accepting.
This describes people who are outgoing, enthusiastic, and lively.
S (Steadiness) style is thoughtful and accepting.
This describes people who are gentle, accommodating, and patient with others’ mistakes.
C (Conscientiousness) style is thoughtful and questioning.
This describes people who are analytical, reserved, and precise.
Everyone is a blend of all four DiSC styles, no one style better or worse than the next.
We believe that these differences in style can be extremely valuable. Once you assess these differences and harness their value, better workplace communication AND healthier organisations become possible.
The Everything DiSC® Assessment
The Catalyst™ Platform
To determine if a tool is reliable, researchers look at the stability and the internal consistency of the instrument. Stability is easy to understand. In this case, a researcher would simply have a group of people take the same assessment twice and correlate the results. This is called test-retest reliability. Internal consistency is more difficult to understand. Here, we have the assumption that all of the questions (or items) on a given scale are measuring the same trait. As a consequence, all of these items should, in theory, correlate with each other. Internal consistency is represented using a metric called alpha. We can use similar standards to evaluate both test-retest and alpha. The maximum value is 1.0 and higher values indicate higher levels of reliability.
Most researchers use the following guidelines to interpret values: above .9 is considered excellent, above .8 is considered good, above .7 is considered acceptable, and below .7 is considered questionable. The reliability estimates, all values were well above the .70 cutoff and all but one were above .80. This suggests that the measurement of DiSC is both stable and internally consistent.
Everything DiSC assessments were updated in 2013 to a computerized adaptive testing format.
Adaptive testing allows an assessment to change depending on a respondent's previous answers. This is useful in cases where the results of a standard assessment are inconclusive.

| Validity | There are many different ways to examine the validity of an assessment. We will provide two such examples here, but many more are included in the full Everything DiSC Research Report. The DiSC model proposes that adjacent scales (e.g., Di and i) will have moderate correlations. That is, these correlations should be considerably smaller than the alpha reliabilities of the individual scales. For example, the correlation between the Di and i scales (.50) should be substantially lower than the Alpha reliability of the Di or i scales (both .90). On the other hand, scales that are theoretically opposite (e.g., i and C) should have strong negative correlations. Data obtained from a sample of 752 respondents who completed the Everything DiSC assessment detailed the correlations among all eight scales show strong support for the model. That is, moderate positive correlations among adjacent scales and strong negative correlations are observed between opposite scales. |
| Comparison groups available for your candidate scores | Working professionals of any gender. The test is based on individual behavioural preferences with no right ot wrong, therefore a 'norm group' is not relevant. |
