Cultural differences in maternal emotion control values and children's expressive flexibility

Expressive flexibility is the ability to express or suppress one's emotions to meet the demands of the situation. Recent work suggests that expressive flexibility is associated with better adjustment. However, few studies have focused on expressive flexibility in children. In addition, there is a dearth of research on possible correlates, such as culture, parental emotion socialization, and socioeconomic status, that may be associated with expressive flexibility competencies in children. The purpose of this study was to investigate cultural differences in children's expressive flexibility, maternal emotion control values (ECVs), and their relations to family socioeconomic status (SES) during middle childhood in a sample of European American (N = 31, M age = 9.61 years; 54.8% males), Korean American (N = 38, M age = 9.16 years; 55.3% males) and South Korean children (N = 77, M age = 9.74 years; 51.9% males). Mothers reported on demographics and their emotion control values. Children's expressive flexibility ability was assessed using a lab-based observational measure. Multivariate analyses of covariance controlling for SES, child age, and gender suggested significant cultural differences in expressive flexibility, with the U.S. children (both European and Korean Americans) scoring higher on expressive flexibility compared to their South Korean counterparts. Results also suggested significant cultural differences regarding maternal ECVs; Korean Americans were more similar to South Koreans, both scoring higher on ECVs than European Americans. Socioeconomic status, but not maternal ECVs, were associated with children's expressive flexibility, independent of child age, sex, and culture.
