Enhancing intercultural task performance: examining the roles of social complexity belief and cultural intelligence

Purpose This study contributes to the literature by explicating why individuals become effective in performing tasks in intercultural context. Drawing from the social axioms theory and intelligence theory, this study specifically investigates and generates new insights about the role of social complexity belief and cultural intelligence (CQ) in enhancing intercultural task performance. Design/methodology/approach Two sets of studies were conducted. Study 1 was conducted in Australia (n = 222) wherein survey data were collected from employees (i.e. self-reports). In a subsequent study which was conducted in the Philippines (Study 2; n = 211), archival data were obtained from the annual performance reviews of the employees (provided by immediate supervisors) in addition to the employees' self-reports. Findings Results are validated in both studies that social complexity belief relates positively and significantly to intercultural task performance. Moreover, results show that social complexity belief influences overall CQ (and its cognitive and metacognitive dimensions) and in the process impacts intercultural task performance. Originality/value This study offers new insights related to intercultural task performance effectiveness. In particular, this study highlights the role of social complexity belief system. Furthermore, this study extends the nomological network of CQ by explicating how an individual's belief can relate to his/her level of CQ which then influences intercultural task performance. Aside from generating knowledge, this study also offers practical insights for human resources practitioners and for employees who are finding new ways to improve and enhance intercultural task performance.
