Research to date has shown longitudinal changes in conscientiousness during early and middle adolescence, but most studies have been conducted in Western countries. The present study aimed to examine the pattern of mean-level conscientiousness change at the transition into early adolescence among a Chinese sample using curve of factors (CUFFS) models. Four waves of data from 661 Chinese children aged 8 years old at baseline in the China Family Panel Studies were used. Parents were asked to rate their children’s level of conscientiousness every 2 years. On average, mean-level conscientiousness showed a decelerating increase. Girls had higher average conscientiousness levels than boys, but they did not differ in change patterns. The inconsistency between the current study and previous research indicates that conscientiousness development may depend, in part, on cultural factors.
