About This Assessment

This DISC assessment measures your behavioral style across four dimensions (Dominance, Influence, Steadiness, and Conscientiousness) to identify your primary and secondary behavioral patterns. It then translates your primary style into estimated Big Five (OCEAN) trait ranges, showing where the DISC model maps clearly to OCEAN and where the translation carries uncertainty.

The 24 Likert-scale questions (6 per dimension) incorporate psychometric best practices including reverse-scored items to reduce acquiescence bias (following Billiet & McClendon, 2000). Each statement is rated from Strongly Disagree to Strongly Agree on a 5-point scale. There are no right or wrong answers: each behavioral style has distinct strengths in different contexts. Question structure is based on the four behavioral dimensions defined by Marston (1928). This assessment has not undergone independent validation testing; treat results as indicative, not diagnostic.

DISC refers to the behavioral model first described by William Moulton Marston in Emotions of Normal People (Kegan Paul, 1928). This assessment is an independent implementation of the DISC behavioral model and is not endorsed by or affiliated with Wiley's Everything DiSC® or other proprietary DISC instruments.

This assessment is one of several free tools built by SEMalytics (founded 2023, semalytics.com), a Seattle-based platform developing content scoring tools grounded in 860+ peer-reviewed papers. It is a free educational self-assessment, not a clinically validated psychometric instrument; it is intended for occupational communication guidance, not clinical diagnosis. Results reflect self-reported behavior, which can be influenced by social desirability bias (Paulhus, 1991): the tendency to answer questions in socially favorable ways rather than accurately. Example output: a primary style (e.g., Dominance) with a secondary style (e.g., Influence), plus estimated OCEAN trait ranges based on the DISC-to-Big-Five mapping.

Why This Matters for B2B Communication

The DISC model proposes that your behavioral style shapes your default communication patterns (Marston, 1928; extended in organizational applications by subsequent practitioners). A high-D writer leads with results and urgency. A high-I writer leads with enthusiasm and stories. A high-S writer emphasizes stability and trust. A high-C writer leads with evidence and precision. Understanding your style reveals which audiences your messaging naturally connects with and which it may be missing. These style descriptions are practitioner characterizations of the model, not validated predictions of any individual's behavior.

How the OCEAN Translation Works

The DISC behavioral model and the Big Five (OCEAN) personality model show theoretical alignment on two dimensions. Comparing the conceptual definitions in Costa & McCrae (1992, Revised NEO Personality Inventory (NEO-PI-R) professional manual) with Marston's original dimension descriptions suggests that Extraversion and Agreeableness show the strongest structural correspondence: high-D and high-I styles align conceptually with higher OCEAN Extraversion, while high-S and high-C styles align with lower; high-S and high-I styles align with higher Agreeableness, while high-D styles align with lower. These are structural parallels between two frameworks, not empirically validated correlations from a dedicated DISC-to-OCEAN mapping study.

Openness, Conscientiousness (Big Five), and Neuroticism fall outside DISC's measurement scope. The ranges shown for these three dimensions are estimates providing directional guidance only, not clinical precision; because DISC does not directly measure these traits, the estimated ranges are intentionally wide and no numeric precision is claimed. For precise scores on all five OCEAN dimensions, take the Big Five (OCEAN) assessment.

Scope note: The DISC-to-OCEAN ranges shown in your results reflect structural parallels between two frameworks based on conceptual alignment in Costa & McCrae (1992). They are not derived from a dedicated DISC-to-OCEAN empirical mapping study. Extraversion and Agreeableness estimates are more reliable; Openness, Conscientiousness, and Neuroticism ranges are directional only.

Compare your style to your writing. Paste your most important B2B message and see how it scores across all five OCEAN dimensions, including the dimensions DISC cannot reliably predict.

Frequently Asked Questions

What does DISC stand for?
DISC stands for Dominance, Influence, Steadiness, and Conscientiousness: the four behavioral dimensions in the model first described by psychologist William Moulton Marston in Emotions of Normal People (1928). Each letter represents a distinct behavioral style with characteristic communication patterns, decision-making tendencies, and motivations.
What is a DISC assessment?
A DISC assessment measures your behavioral style across four dimensions: Dominance, Influence, Steadiness, and Conscientiousness. It helps you understand how you communicate, make decisions, and respond to challenges.
How does DISC relate to the Big Five (OCEAN) personality model?
DISC and the Big Five (OCEAN: Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) are separate frameworks measuring overlapping but distinct aspects of personality. Research comparing the two models suggests that DISC Extraversion (high-D, high-I) maps conceptually to OCEAN Extraversion, and DISC Steadiness and Influence map to OCEAN Agreeableness. The remaining three OCEAN dimensions (Openness, Conscientiousness, Neuroticism) fall largely outside DISC's measurement scope. This tool includes an estimated OCEAN translation based on those structural parallels, but for precise scores on all five dimensions use the Big Five (OCEAN) assessment.
What does a high D (Dominance) score mean?
A high Dominance score indicates a direct, results-oriented behavioral style. High-D individuals prioritize outcomes over process, make fast decisions, and are comfortable with conflict. In B2B communication, high-D writers lead with conclusions, use direct language, and focus on results and ROI rather than relationship-building.
What does a high I (Influence) score mean?
A high Influence score indicates an enthusiastic, people-oriented behavioral style. High-I individuals are motivated by social recognition and collaboration, communicate with energy and optimism, and build rapport easily. In B2B communication, high-I writers use storytelling, focus on people and relationships, and lead with enthusiasm over data.
What does a high S (Steadiness) score mean?
A high Steadiness score indicates a patient, reliable, team-oriented behavioral style. High-S individuals value stability and consistency, prefer collaborative environments, and are motivated by security and sincerity. In B2B communication, high-S writers emphasize trust, long-term relationships, and peer validation over urgency or novelty.
What does a high C (Conscientiousness) score mean?
A high Conscientiousness score indicates an analytical, precision-focused behavioral style. High-C individuals are motivated by accuracy and quality, prefer evidence-based decision-making, and tend toward systematic thinking. In B2B communication, high-C writers lead with data and specifics, provide detailed justifications, and prefer precision over broad claims.
Is this the same as the DiSC® assessment by Wiley?
No. This is a free assessment based on William Moulton Marston's original DISC behavioral model (1928). Everything DiSC® is a separate, proprietary instrument published by Wiley. Our tool adds a Big Five (OCEAN) translation that the standard DISC model does not include.
How accurate is a free DISC assessment?
This assessment measures the same four behavioral dimensions as commercial DISC tools using 6 items per dimension with reverse-scored items to reduce acquiescence bias. Validated short-form personality scales of this structure typically report internal consistency (Cronbach's alpha) in the 0.70–0.85 range per dimension; this free tool itself has not undergone a formal standalone validation study, so treat results as indicative rather than definitive. The Big Five (OCEAN) assessment provides greater precision on all five dimensions, including Neuroticism, which DISC cannot measure.
