The longitudinal associations between popularity, overt aggression, and relational aggression were assessed in middle school and high school cohorts drawn from a large urban Northwest Chinese city. The middle school (n = 880; 13.33 years.) and high school samples (n = 841; 16.66 years.) were each followed for 2 years. In the concurrent regression analyses, overt aggression was more strongly and consistently associated with popularity than relational aggression after controlling for likability. Cross-lagged analyses revealed that popularity predicted subsequent increases in overt and relational aggression throughout middle and high school whereas overt aggression at 7th and 10th grade predicted increases in popularity 1 year later. These findings provide further evidence that popularity is associated with aggression and suggest that overt and relational aggression may be a consequence rather than a contributor to popularity in Chinese adolescents.
