DiSC^® Dimensions of Behavior provide a nonjudgmental language for exploring behavioral issues across four primary dimensions:

• Dominance: Direct and Decisive
D's are strong-willed, strong-minded people who like accepting challenges, taking action, and getting immediate results.

• Influence: Optimistic and Outgoing
I's are "people people" who like participating on teams, sharing ideas, and energizing and entertaining others.

• Steadiness: Sympathetic and Cooperative
S's are helpful people who like working behind the scenes, performing in consistent and predictable ways, and being good listeners.

• Conscientiousness: Concerned and Correct
C's are sticklers for quality and like planning ahead, employing systematic approaches, and checking and re-checking for accuracy.

The reason why it works

The DiSC questionnaire is available online. The instrument uses a measurement technique called "forced-choice": the participants are presented four adjectives and asked to choose, among the four, the one that most reflects them and the one that reflects less.

The advantage of this structure is that it reduces distortions due to social desirability. The social scientists have in fact occurred that, in undergoing an evaluation tool, the majority of individuals tend to respond in order to show a good perspective of them. This is not necessarily a conscious attempt to deceive the instrument, but rather the natural desire to think and present selves in the best light.

The "forced-choice" format reduces the influence of this trend, forcing players to choose from several options, all socially desirable.

The DiSC questionnaire is available in 30 languages. Validation of the four scales of the DiSC Classic (D - Dominance, i - influence, S - Steadiness and C - Conscientiousness) was measured according to parameters of reliability and validity, showing more than satisfactory rates. A standardization has been completed in different countries.
