The authors examined the relations between two socially oriented dimensions of student motivation and academic achievement of Native (Navajo) American and Anglo American students. Using confirmatory factor analysis, a multidimensional and hierarchical model was found to explain the relations between performance and social goals. Four first-order goal constructs (competition, social power, affiliation, and social concern) represented by 2 higher order factors (performance and social dimensions) were found to be invariant for two cultural groups of high school students in the United States: Navajo (n = 1,482) and Anglo (n = 803). The findings suggest that the effects of performance goals are relatively stronger, and are similarly strong cross-culturally. However, Navajo students were relatively lower in achievement scores and competition goals but higher in social concern.
