Development of self-concept clarity from ages 11 to 24: Latent growth models of Chinese adolescents

This study examined the growth trajectory of self-concept clarity (SCC) and explored the influence of this trajectory on the development of life satisfaction (LS) and positive affect (PA) among Chinese adolescents (N = 2001, 56.97% females). Results of latent growth models showed no significant mean-level change of SCC across three waves in a year. However, significant inter-individual variability was presented in the developmental patterns of SCC over time. Specifically, older adolescents showed higher initial levels of SCC; and males were related to increased SCC in development rates. Moreover, we found gender-specific nature of the relationship between SCC and well-being outcomes (e.g., LS and PA). Our results have significant practical implications for mental health programs in adolescence.
