Cultural intelligence (CQ) has been regarded as a key factor in international business success. A recently validated scale, the Business Cultural Intelligence Quotient (BCIQ), refines the CQ concept by applying it exclusively to the business context. The BCIQ aims at predicting long-term cross-cultural success using a combination of CQ factors, cognitive features, and measurable independent variables (Alon et al., 2016b). Using the multigroup exploratory factor analysis approach, we found low measurement invariance for the (BCIQ) instrument across eight countries (Austria, Chile, Colombia, Greece, Philippines, Poland, Spain, and Venezuela). Global knowledge was included as a covariate in the invariance test. We found that type of performance is related to some BCIQ dimensions in our multicountry sample of professionals. Our results provide additional evidence about the construct validity of the BCIQ and its appropriateness for cross-cultural applications. By knowing that the BCIQ is a reliable cross-cultural instrument for the measurement of CQ applied to the business context, managers can benefit by identifying the right individuals for international business assignments.
