Cross-cultural research in many psychology-related fields is becoming commonplace. To further the research in a methodologically rigorous fashion it is critical to be able to measure adequately the constructs under investigation. This study (N = 238) examined three measures used to assess individualist and collectivist orientations. The internal structure of the scales and their inter-relatedness were evaluated. Results suggested that there is little overlap between the scales, and that Triandis' (1996) Horizontal and Vertical Individualism and Collectivism scale presented the best measure of the constructs.
