It's Your Personality

Benefit Or Burden?

by Mary Jo Huard

The DiSC Personality model is built on the idea that understanding yourself and others is a key to success in today's highly complex world.  Other than slight modifications in our behavior as a result of significant life experiences, most of us carry much the same behavior patterns throughout our lifetime.  This stability of our core pattern gives us a sense of identity.  By helping us better understand ourselves and others, the DiSC learning instrument can play a central role in helping an organization develop a healthy, productive, positive-thinking culture. 

 

The DiSC model of human behavior was presented in the 1920's by William Marston, a physiological psychologist, in his book "Emotions of Normal People".  (Hippocrates created the first four-factor theory of temperament in 400 B.C.).  Marston's model is unique in that it is a two-axis, four-factor model with Dominance and Conscientiousness on one axis and Influence and Steadiness on the other axis.  It is assumed that most people show all four of these dimensions at times; however, it is also assumed that an individual develops a style of behavior that puts particular emphasis on certain aspects and less on others. 

 

Dr. John Geier and others modified Marston's model based on the work in personality theory done in the 40's and 50's.  Dr. Geier and Carlson Learning Company published a unique forced-choice, self-reporting instrument in 1972 that was self-administering, self-scoring, and self-interpreting.  The DiSC model has two significant elements (axis) that define a person's primary behavioral style: 

1.    One element describes the perception a person has about the favorableness of her/his environment (work, relationship, social).

2.    The other element is how much power a person perceives him/herself to have within an environment.

 

It is the combination of a person's perception of favorableness and unfavorableness of the environment and the perception of his/her personal power in  relation  to the  environment that determines a person's behavioral style. The dynamic interaction of the two elements explains how an individual may behave differently from one environment to another. 

The difference in behavior represents a flexible or adaptable response based on differences in a person's (1) perception of the degree of favorableness of the environment and (2) perception of the degree of his/her power in that environment.  The cumulative responses of an individual become characterized as a "pattern" of behavior that remains relatively predictable, unless there is a significant shift in either of these two perceptions of self.

Instrument Construction

·        Empirical Validity:  The DiSC model has been compared to several accepted instruments and was found to demonstrate construct validity (measures what it says that it measures). 

·        Face Validity:  Based on interview research, a typical respondent accepts as accurate 90-95% of their DiSC interpretation.

·        Reliability Analysis shows to what degree all of the items within a scale contribute in a consistent manner to the total score of the scale. 

SUMMARY:  Each of us is a blend of all four behavioral dimensions.  The frequency and intensity with which we use certain behavioral dimensions develop a core pattern or core behavioral style for each of us.  People are effective if they know their style and its strengths and limitations.  They are successful if they can evaluate the needs of others and adapt or adjust their style to meet those needs.
