The present research examined: (a) the co-development of chores and effortful control, and (b) the prospective impact of effortful control development (i.e., initial levels and the trajectory of effortful control from late childhood through adolescence) on work outcomes in young adulthood. We used data from a longitudinal study of 674 Mexican-origin youth assessed at ages 10, 12, 14, 16, and 19. We found no evidence of co-developmental associations between chores and effortful control, but we found that higher initial levels of effortful control (age 10) predicted working-student status, less job stress, and better job fit, and steeper increases in effortful control from age 10 to 16 predicted higher job satisfaction and job autonomy in young adulthood (age 19).

Shyness, or the tendency to be inhibited and uncomfortable in novel social situations, is a consequential personality trait, especially during adolescence. The present study examined the development of shyness from late childhood (age 10) through adolescence (age 16) using data from a large, longitudinal study of Mexican-origin youth (N = 674). Using both self- and mother-reports of shyness assessed via the Early Adolescent Temperament Questionnaire-Revised, we found moderate to high rank-order stabilities across two-year intervals and a mean-level decrease in shyness from age 10 to 16. Anxiety and depression were associated with higher initial levels of shyness, and anxiety was associated with greater decreases in shyness from age 10 to 16. Contrary to predictions, neither nativity (country of birth) nor language proficiency (English, Spanish) was associated with the development of shyness across adolescence. Thus, youth generally decline in shyness during adolescence, although there is substantial individual variability in shyness trajectories.
