The aim of this study is to assess the cross-cultural applicability of the Chinese version of the Inventory of School Motivation (ISM; McInerney & Sinclair, 1991) in the Hong Kong context using both within-network and between-network approaches to construct validation. The ISM measures four types of achievement goals: mastery, performance, social, and extrinsic goals. A total of 697 high school students participated in the study. Results of the within-network test showed that the ISM had good internal consistency reliability. Confirmatory factor analysis supported the hypothesized four-factor structure. In addition, multigroup confirmatory factor analyses showed factorial invariance across students of different genders, year levels, and school types. The between-network test indicated that the achievement goals assessed by the ISM correlated systematically with different aspects of students' self-concepts. These findings provide evidence of the applicability of the ISM among Hong Kong Chinese students. Implications for cross-cultural research are discussed. (Contains 4 tables, 1 figure, and 3 notes.)
