The Cross-Cultural Adaptability Inventory (CCAI) was developed in the US as a tool to provide feedback on one's emotional resilience, flexibility/openness, perceptual acuity and personal autonomy -- dimensions theorised to be important for successful cross-cultural interaction. The instrument was administered to a group of 74 soldiers of the Singapore Armed Forces who were identified for a UN peace support operation. Subsequently, criterion data were obtained during their deployment with regard to their adaptability, stress tolerance and performance in the foreign country. An earlier evaluation of the CCAI scales indicated the lack of structural equivalence and convergent-discriminant validity. However, there was good criterion-related validity for emotional resilience, flexibility/openness and perceptual acuity. Given the latter important finding, an attempt was made to improve the scales' structural and convergent-discriminant validity, while retaining their internal consistencies and criterion-related validity. "Poor" items were identified and removed based on language inappropriateness, low item-total score correlation and poor factor loadings. This paper presents the re-evaluation of the validity of CCAI based on a reduced set of items. The findings showed that although the internal structure had somewhat improved, i.e., became more similar to the structure found in U.S., the convergent- discriminant validity of the scales remained largely unchanged. The future direction will be to test the revised CCAI on other samples in Singapore and abroad, as well as to develop and test new items to improve the convergent-discriminant validity of the scales.
