DiSC Model of Behavior

In 1928, Dr. William Moulton Marston published Emotions of Normal People , a book that laid the ground work for what would become today's DiSC assessments.  Marston was interested in theories that helped explain emotions and their physical manifestations.  In Emotions of Normal People, Marston proposed that people express their emotions through four primary responses.  While Marston didn't develop a instrument to measure his model or determine one's primary behavioral style, over time, many researchers have continued to develop and refine such instruments over the past 80 years, ultimately resulting in the DiSC Behavioral Profile.  While the labels for the four original styles have since been updated, Marston's origninal theory remains the archetype of modern DiSC instruments such as the DiSC model described here.

The four DiSC styles are:

Dominance: describes people who are result-oriented, driven and forceful.  They usually have strong opinions about how things should be done and are direct, if not blunt, with those opinions.  They are often described as competitive, strong-willed, and demanding.

Influence: describes people are outgoing, enthusiastic, and friendly.  They're quick to seek new social opportunities and are very talkative. They are often described as high-spirited, positive, and social.

Steadiness: describes people who are gentle and accommodating.  They're very considerate of other people's needs and show a great deal of patience.  They work to create a stable and harmonious environment and are often described as a cooperative team player.

Conscientiousness:  describes people who are analytical and reserved.  They place a high value on accuracy and take a systematic approach to their work.  They are often described as being objective and composed.
