In the DiSC Classic assessment, participants are shown 28 boxes that contain four words each. In each box, they are asked to choose one that is most like them and one that is least like them (ipsative/forced-choice scale). Consequently, participants review a total of 112 words.
Example of Ipsative/Forced-Choice scale used in DiSC Classic assessments:
One of the original reasons for using the forced-choice measurement methodology is because it greatly reduced the social desirability of responses. That is, a participant can only choose one response as most like them even if all of the words are desirable and is forced to choose one as least like them even if it’s not very desirable.
In the Everything DiSC assessment, participants are shown 79 adjectives and asked to indicate on a five-point likert scale how frequently each adjective describes them. Because the Everything DiSC assessment is electronically scored, the computerized scoring algorithm automatically adjusts for the social desirability of responses. Consequently, participants are left with more freedom to answer the questions in a way that truly describes them. That is, they are not forced to select a response that does not feel optimal to them. For this reason, participants generally find it easier to respond to the Everything DiSC assessment than to the DiSC Classic assessment.
Example of Likert Scale used in Everything DiSC assessments:
In addition, because they are reviewing only 79 words, rather than 112 words, the assessment usually takes less time. After a participant has finished the assessment, the profile is scored. Each of the 79 adjectives is assigned to one of eight DiSC scales: D, Di, i, iS, S, SC, C, or CD. Although not reported in the actual profile, participants receive scores on each of these eight scales. Each of these eight scales is weighted according to its location on the DiSC circle, and a participant’s location in the DiSC circle is calculated.
Because the Everything DiSC assessment measures people on eight points around the DiSC circle rather than on four points, like the DiSC Classic assessment, it provides more precision about a participant’s true DiSC style. For instance, instead of simply measuring a person on the S and C scales, the Everything DiSC assessment measures a person on S, SC, and C scales. This precision gives us a better idea of where a person is located within the DiSC circle.
