This study investigated the dimensionality of a 21-item questionnaire measure of idiocentrism-allocentrism (the within-culture measure of individualism-collectivism) within the context of Sri Lankan culture. A survey of 438 Sri Lankan respondents, sampled from a wide variety of demographic contexts, provided data. Factor analysis indicated that idiocentrism and allocentrism are two independent, unipolar factors, rather than opposite poles of a single, bipolar dimension. The implications are discussed in the context of existing and future cross-cultural (etic) and within-cultural (emic) research on individualism-collectivism.
