The construct of cultural intelligence (“CQ”) consists of four facets (metacognitive, cognitive, motivational, and behavioural). The objective of this study is to identify the CQ facet best able to predict overall intercultural adjustment. Twenty independent hierarchical multiple regression models were performed on a sample of 189 international students studying at Czech universities in a foreign language. The results showed that the CQ facet that best predicts intercultural adjustment, when controlling for demographic variables and preparedness for study abroad, is the motivational CQ facet. However, a significant relationship was also discovered for all remaining CQ facets and intercultural adjustment.
