The present study developed and assessed reliability and validity of a new instrument, the Intercultural Effectiveness Scale (IES). Based on a review of the literature, 76 items important for intercultural effectiveness were generated. A total of 653 college students rated these items in two separate stages and generated a 20-item final version of the instrument which contains six factors. An assessment of concurrent and predictive validity from 246 participants in the final stage indicates that the IES was significantly correlated with other related scales. Implications and limitations of the study are discussed as well.
