Measures of Cognitive Complexity and Its Development in Chinese Adolescents

There are various controversies over the measurement of cognitive complexity and few studies concerning its development in adolescents, especially in China. Based on a sample of 234 Chinese adolescents from Grades 7 through 11, the present study first compared 2 instruments and 12 corresponding indices of cognitive complexity—11 traditional and new forms of cognitive complexity scores on the Repgrid, and 1 score on the Role Category Questionnaire (RCQ)—then adopted the most appropriate tool to investigate the development of cognitive complexity. The results showed that the RCQ may have relatively more construct validity than the Repgrid in terms of the assessment of adolescents’ cognitive complexity. Using the RCQ, it was found that adolescents of different grades, gender, peer status, and academic achievement had different levels of cognitive complexity.
