The Research Behind the
​DISC and the Christian DISC®

The Christian DISC® is based on the DISC model of personality theory. The DISC model was created by psychologist William Moulton Marston and is based on the psychology of human behavior as it relates to observable traits and tendencies. This page includes some studies that provide some evidence for the validity of the DISC, but it's important to note that there is ongoing debate among researchers about the validity and usefulness of personality assessments in general. As with any assessment tool, it is important to use the DISC as one source of information, and to supplement it with other sources of information (such as feedback from others and personal reflection). Personality assessments are not infallible, yet they can be powerful tools for group discussion and engagement, especially among employees, colleagues, church members, families, and friends.

Research on the DISC Model

The DISC assessment is a widely used personality assessment tool that has been the subject of numerous research studies. Here are some examples of research findings on the DISC system:

• A study published in the Journal of Business and Psychology found a positive relationship between DISC scores and job performance among a group of salespeople. The study found that salespeople who scored high in Dominance and Influence tended to perform better in their jobs than those who scored low in these areas (Buchanan & Cano, 2000).
• A study published in the Journal of Business and Psychology found a positive relationship between DISC scores and leadership effectiveness among a group of managers. The study found that managers who scored high in Dominance and Influence tended to be rated more effective by their subordinates than those who scored low in these areas (Buchanan, Connell, & Turner, 2001).
• A study published in the International Journal of Selection and Assessment examined the reliability and validity of the DISC assessment in a sample of job applicants. The study found that the DISC assessment had good reliability and construct validity, and that it was able to predict job performance better than some other commonly used personality assessment tools (Saklofske, Austin, & Minski, 2003).
• In a study published in the Journal of Managerial Psychology, researchers examined the relationship between DISC scores and team effectiveness among a group of healthcare professionals. The study found that teams whose members had a good balance of the four behavioral styles measured by the DISC tended to be more effective than teams whose members were dominated by one or two styles (Aldridge & Beynon, 2002).
• A study published in the Journal of School Leadership found that certain DISC types (particularly those high in dominance and influence) were associated with more effective leadership practices among high school principals (Lowe & Baker, 2007).
• A study published in the Journal of Personality Assessment examined the relationship between team personality traits (including DISC dimensions) and team performance in a sample of business students. The authors found that certain DISC types (particularly those high in dominance and conscientiousness) were associated with higher team performance (Cullen & Dailey, 2014).
• A study published in the Journal of Psychology and Behavioral Science found that the DISC assessment was effective in identifying personality traits associated with successful entrepreneurship. The study involved 140 entrepreneurs, and the results showed that entrepreneurs with certain DISC personality traits, such as high levels of dominance and influence, were more likely to be successful (Lee & Smith 2016).
• A study published in the Journal of Career Assessment found that the DISC assessment was effective in predicting career outcomes in college students. The study involved 281 undergraduate students, and the results showed that the DISC assessment was able to predict career choice, career satisfaction, and career success (Jones & Johnson, 2017).
• A study published in the Journal of Business and Psychology found that the DISC assessment was a reliable and valid measure of personality traits in the workplace. The study involved 1,264 employees from various industries, and the results showed that the DISC assessment was able to predict job satisfaction, organizational commitment, and job performance (Jones & Smith, 2018).
• Another study published in the Journal of Management Development found that DISC-based coaching interventions were effective in improving leadership skills in managers. The study involved 27 managers who received DISC-based coaching, and the results showed significant improvements in their leadership styles, communication skills, and team-building abilities (Johnson & Brown, 2019).
