The horizontal and vertical attributes of individualism and collectivism in a Spanish population.

The authors examined the dimensionality and factorial structure of individualism and collectivism in Spanish participants (N = 526). A series of confirmatory factor analyses were performed on responses to the 32-item individualism-collectivism measure reported by T. M. Singelis, H. C. Triandis, D. S. Bhawuk, and M. Gelfand (1995). Consistent with earlier data, the best fitting model was multidimensional: a vertical versus a horizontal attribute crossed with individualism and collectivism dimensions. Whereas the overall fit of the data to a LISREL model was moderate, additional self-report data on respondents' interpersonal experiences supported the construct validity of the 4 factors. The authors suggest that the additional complexity is useful in explaining Spanish social behavior.
