Age and gender differences in self-control and its intergenerational transmission.

Abstract

Few studies have been conducted in people of Asian descent that have reported to demonstrate the distinct developmental trends in good self-control and poor control. To fill this gap, we conducted a national cross-sectional survey among adolescents and young adults in China to further clarify the age and gender differences in self-control from a dual-systems perspective. A total of 2910 adolescents (female, n = 1698) and their parents from five different provinces in China were surveyed using the Dual-Modes of Self-Control Scale (DMSC-S) and the Parents' Perceived Self-Control Scale. The mean age of the adolescent sample was 17.47 years (ranging from 12.50 to 25.42 years). Boys exhibited greater good self-control than girls. Poor control increased between 12 and 17 years of age and declined thereafter; however, good self-control increased over the entire study period. Both good self-control and poor control in student participants were significantly associated with parents' perceived self-control; moreover, the association between good self-control and parental self-control was mediated by SES. The roles of age, gender, parental self-control and SES varied in a dual-systems model of self-control: good self-control and poor control. Implications of these results are discussed.
