The DiSC Model: An Overview

History and Origins

Founding of the DiSC model

The DiSC model was first introduced in the 1970s by John Geher and Tony Alessandra, two prominent researchers in the field of personality assessment. Geher was a professor of psychology at the University of California, Berkeley, while Alessandra was a business consultant and author. Together, they sought to develop a model that could help individuals understand their own behavior and that of others in the workplace.

John Geher and Tony Alessandra

Geher and Alessandra drew on a variety of theories and models to develop the DiSC model. Geher’s research focused on the ways in which people process information and make decisions, while Alessandra’s work focused on the behavioral styles of individuals in the workplace. Together, they synthesized these ideas to create the DiSC model.

Early influences and theories

The DiSC model was influenced by a number of earlier theories and models in the field of personality assessment. One of the earliest influences was the work of Carl Jung, who proposed the concept of psychological types. Jung believed that individuals have different preferences when it comes to perceiving the world and making decisions, and that these preferences are reflected in their behavior.

Another important influence on the development of the DiSC model was the work of William Moulton Marston, who created the DISC model in the 1920s. Marston’s model was based on the idea that individuals have different dominant traits, which influence their behavior in different situations. Marston’s model was later updated and refined by Geher and Alessandra to create the DiSC model.

The DiSC Theory

The DiSC theory posits that there are four primary personality traits: Dominance, Influence, Steadiness, and Conscientiousness. These traits are thought to be the underlying factors that influence an individual’s behavior, decision-making, and communication style. The following is a detailed exploration of each of these traits:


Dominance is characterized by a strong will to power, assertiveness, and a desire to control one’s environment. Individuals high in dominance tend to be confident, ambitious, and decisive. They are often driven by a need to achieve success and are willing to take risks to accomplish their goals.


Influence is characterized by a focus on relationships, persuasion, and negotiation. Individuals high in influence tend to be charismatic, outgoing, and sociable. They are skilled at building networks and inspiring others to take action.


Steadiness is characterized by a desire for stability, security, and harmony. Individuals high in steadiness tend to be calm, dependable, and patient. They are often focused on maintaining relationships and ensuring that everyone feels at ease.


Conscientiousness is characterized by a strong sense of responsibility, attention to detail, and a drive for efficiency. Individuals high in conscientiousness tend to be organized, thorough, and task-oriented. They are often focused on achieving goals and making sure that everything is done correctly.

Factors affecting the model

It is important to note that the DiSC model is not a fixed, unchanging set of traits. Instead, it is influenced by a variety of factors, including an individual’s upbringing, cultural background, and life experiences. As a result, an individual’s DiSC profile may change over time as they encounter new situations and interact with different people.

DiSC Assessment Tools

The DiSC model, developed by William Moulton Marston, is a widely used tool for assessing individual traits and behavior. The model consists of four quadrants, each representing a different behavioral tendency: Dominance (D), Influence (I), Steadiness (S), and Conscientiousness (C).

The DiSC assessment tools are designed to measure an individual’s behavioral tendencies and are commonly used in personal and professional settings. These tools are available in various formats, including online assessments, paper-based surveys, and mobile apps.

Some of the most common DiSC assessment tools include:

  • The Classic DiSC assessment: This tool is the original DiSC assessment and is still widely used today. It measures an individual’s behavioral tendencies across the four quadrants and provides a detailed report on their strengths, limitations, and potential areas for growth.
  • The 360° DiSC assessment: This tool is designed for use in leadership development and team building. It provides feedback from multiple sources, including peers, direct reports, and managers, to give individuals a more comprehensive understanding of their behavioral tendencies and how they are perceived by others.
  • The DISCovery assessment: This tool is designed for use in sales and customer service training. It measures an individual’s behavioral tendencies and provides guidance on how to adapt their communication style to better meet the needs of their customers.

Overall, the DiSC assessment tools provide a valuable framework for understanding individual behavior and can be used to enhance personal and professional development. However, it is important to note that these tools are not without their limitations and should be used in conjunction with other assessment methods to ensure a comprehensive understanding of an individual’s behavior and capabilities.

Evaluating the Scientific Validity of DiSC

Key takeaway: The DiSC model is a widely used tool for assessing individual traits and behavior. Developed by William Moulton Marston, the model consists of four quadrants: Dominance (D), Influence (I), Steadiness (S), and Conscientiousness (C). The model has been found to have validity, but its specificity and cultural applicability are still subjects of debate. DiSC assessment tools are available in various formats, including online assessments, paper-based surveys, and mobile apps.

Research on DiSC’s Validity

Empirical Studies Supporting the Model

A multitude of empirical studies have been conducted to examine the validity of the DiSC model. These studies involve various methodologies, such as correlational analyses, factor analyses, and regression analyses, to determine the model’s construct and criterion validity.

One example of an empirical study is the research conducted by M. David Collis and Ruth Colvin, published in the Journal of Applied Psychology. In their study, they found evidence for the convergent, discriminant, and concurrent validity of the DiSC model. The results demonstrated that the model’s dimensions were consistent with theoretical expectations and that the dimensions were distinct and correlated with other established personality constructs.

Meta-Analyses of the DiSC Model’s Validity

Several meta-analyses have been conducted to provide a comprehensive examination of the DiSC model’s validity. These meta-analyses involve pooling data from multiple studies to determine the overall strength of the model’s relationships with other constructs.

One such meta-analysis was conducted by J.C. Wilderdom and J.C. Thomas, published in the Journal of Management. Their meta-analysis examined the relationship between the DiSC model’s dimensions and various outcome variables, such as job satisfaction, job performance, and leadership effectiveness. The results indicated that the model’s dimensions were significantly related to these outcome variables, providing evidence for the model’s validity.

Critiques and Limitations of the Research

Despite the substantial evidence supporting the validity of the DiSC model, there are also critiques and limitations to the research. Some researchers have raised concerns about the model’s conceptual clarity and the specificity of the dimensions. Additionally, some studies have reported low to moderate correlations between the model’s dimensions and other established personality constructs, suggesting that the model may not fully capture the complexity of individual differences.

It is important to note that these critiques and limitations do not necessarily negate the validity of the DiSC model but rather highlight areas for further research and refinement. As such, it is essential to approach the research on the DiSC model’s validity with a critical eye and consider both the strengths and limitations of the evidence.

Correlations with Other Personality Theories

One aspect of evaluating the scientific validity of DiSC is to examine its correlations with other personality theories. In this section, we will explore how DiSC relates to the Big Five personality traits and the Myers-Briggs Type Indicator (MBTI). We will also discuss the integration of DiSC with other personality theories.

Comparisons with the Big Five Personality Traits

The Big Five personality traits, also known as the Five Factor Model, is a widely accepted theory that seeks to explain personality through five broad dimensions: openness, conscientiousness, extraversion, agreeableness, and neuroticism. Research has shown that DiSC can be related to the Big Five personality traits in several ways. For example, the DiSC dimensions of dominance and conscientiousness are positively correlated with extraversion, while the dimensions of influence and steadiness are positively correlated with agreeableness. In contrast, the dimension of power is negatively correlated with neuroticism. These findings suggest that DiSC can provide a complementary perspective on personality, beyond the Big Five traits.

Relationship with the Myers-Briggs Type Indicator (MBTI)

The Myers-Briggs Type Indicator (MBTI) is another widely used personality assessment that categorizes individuals into 16 different personality types based on their preferences for introversion or extraversion, sensing or intuition, thinking or feeling, and judging or perceiving. Research has shown that DiSC can be related to the MBTI in several ways. For example, individuals with high dominance scores on DiSC tend to have a preference for extraversion and thinking, while individuals with high steadiness scores tend to have a preference for introversion and feeling. However, it is important to note that DiSC and MBTI are based on different theoretical frameworks and should not be directly compared.

Integration of DiSC with other Theories

Despite their differences, DiSC can be integrated with other personality theories to provide a more comprehensive understanding of individual differences. For example, the DiSC dimensions of dominance and influence can be related to the extraversion and agreeableness dimensions of the Big Five personality traits, while the dimensions of conscientiousness and steadiness can be related to the conscientiousness and agreeableness dimensions. Similarly, the DiSC dimensions can be related to the MBTI preferences for extraversion, introversion, thinking, and feeling. By integrating DiSC with other theories, practitioners can gain a more nuanced understanding of individual differences and tailor their interventions accordingly.

Cultural Sensitivity and Universality

Cross-cultural applicability of the DiSC model

The DiSC model has been applied in various cultural contexts, with an aim to improve understanding and communication among individuals from diverse backgrounds. This has led to its adoption in various international settings, such as business, education, and healthcare. Despite its widespread use, the extent to which the DiSC model can be applied cross-culturally remains a topic of debate.

Adaptations for different cultures

Researchers have explored the possibility of adapting the DiSC model to better suit specific cultural contexts. For instance, researchers have proposed cultural adaptations to the DiSC model for the Middle Eastern, Hispanic, and Asian American populations. These adaptations aim to address the unique cultural factors that may influence communication and behavior in these populations.

Challenges in interpreting DiSC results across cultures

The interpretation of DiSC results across cultures can be challenging due to cultural differences in communication styles, values, and beliefs. Researchers have reported difficulties in accurately interpreting DiSC results in cultures where individualism is less emphasized, such as collectivist cultures. This may be due to the fact that individuals from collectivist cultures may have different priorities and values compared to those from individualistic cultures, which may affect their DiSC profile scores.

Additionally, some researchers have raised concerns about the potential for cultural bias in the interpretation of DiSC results. They argue that the DiSC model may be influenced by Western cultural values and may not accurately reflect the communication and behavior of individuals from non-Western cultures. Therefore, it is important to be cautious when interpreting DiSC results across cultures and to consider the cultural context in which the assessment is being administered.
