More than 1,000 journal articles by scholars and research teams from all over the world have shown the validity of the CQ Assessment and have shown that Cultural Intelligence predicts work performance, leadership effectiveness, creativity, and a host of other skills.

CQ Key Research Question

What is the difference between individuals and organizations that are effective in today’s multicultural, globalized world and those that fail?

Going beyond existing notions of cultural sensitivity and awareness, CQ captures the capabilities of individuals and organizations that successfully and respectfully accomplish their objectives, whatever the cultural context.

CQ Model

Earley and Ang built on Sternberg and Detterman’s multiple loci framework on intelligence to argue that intelligence must go beyond mere cognitive abilities. Ang and Van Dyne developed an initial nomological network of predictors and outcomes of the four key CQ capabilities:

CQ Drive (Motivational CQ): the level of a person’s interest, persistence, and confidence to function in culturally diverse settings.

CQ Knowledge (Cognitive CQ): the level of a person’s understanding about how cultures are similar and how they are different.

CQ Strategy (Meta-cognitive CQ): the degree to which a person plans for, remains aware during, and checks after multicultural interactions.

CQ Action (Behavioral CQ): the extent of a person’s flexibility and appropriate use of a broad repertoire of behaviors and skills during multicultural encounters.

The History of the Cultural Intelligence Scale
(CQs and E-CQs)


Following rigorous scale development procedures over many years, the Cultural Intelligence Scale (CQS) was developed, refined, validated, and cross-validated using a series of culturally diverse samples that included executives, expats, professionals, students, and members of multicultural teams throughout the world.

Expanded CQ Scales

The Expanded Cultural Intelligence Scale (E-CQS) provides even more nuanced feedback based on separate scales for each of thirteen sub-dimensions. Results demonstrate strong incremental, discriminant, and predictive validity of the CQS and E-CQS. The CQS and E-CQS are the basis of the CQ Self-Assessments and the CQ Multi-Rater Assessment (360°).

A Valid System

Research demonstrates strong incremental and, discriminant validity of these scales. CQ has predictive validity above and beyond social desirability, personality, experience, and a host of other constructs. Accordingly, it’s not easy to “game” the assessment and there’s a high level of convergence between self-ratings and observer- ratings across several thousand participants., Research also demonstrates the practical utility of both self-report and observer-report versions of the CQ scales.
