Does Grit Compensate for Family Background Disadvantage in Predicting Mental Health Difficulties? A Longitudinal Study of Chinese Migrant and Urban Children.

The significant population of Chinese rural-to-urban migrant children has sparked considerable domestic and international concern regarding their disadvantaged family circumstances and their escalating prevalence of internalizing and externalizing problems. Derived from the resource substitution hypothesis, non-cognitive factors such as personality traits may act as "substitution" resources for educational outcomes of children from less privileged families. Yet, the compensatory role of personality traits as substitution resources in children's mental health has received limited attention, including that of migrant children. This study examined the interplay of trait-like grit and family SES on emotional and conduct problems among Chinese migrant and urban children. The current sample consisted of 770 migrant children (Mage = 10.45 and SDage = 0.68 years; 38.4% girls) and their 222 urban counterparts (Mage = 10.34 and SDage = 0.46 years; 45.5% girls). Moderated polynomial regressions with response surface analysis on a two-wave data with an interval of over six months showed that grit served as a "substitution" resource for the less socioeconomically advantaged children. The compensatory effect of perseverance of effort on urban children's emotional problems and that of consistency of interest on migrant children's conduct problems were visualized. Moreover, the two compensatory effects were found to be robust and unique, even after children's effortful control, a grit-related construct, was taken into account. These findings not only support the resource substitution hypothesis, but also underscore the protective role that grit plays in children under less privileged environments.

The impact of family socioeconomic status and parenting styles on children's academic trajectories: A longitudinal study comparing migrant and urban children in China.

The positive development of migrant children in China is hampered due to their unequal accessibility to quality urban education resources. This research aimed at exploring the developmental trajectories of migrant and urban children's literacy and mathematics performance, as well as the impact of family socioeconomic status (SES) and parenting styles, including the mediating effect of parenting styles, by comparing migrant children with their urban counterparts. Growth mixture modeling identified distinguishable trajectories of mathematics development for migrant children (i.e., "falling behind" and "keeping pace" groups) and urban children (i.e., "catching up" and "keeping pace" groups), as well as distinguishable trajectories of literacy development for migrant children (i.e., "jumpstarting" and "keeping pace" groups) and urban children ("falling behind" and "steadily progressing" groups). Multinomial logistic regression analyses further clarified that authoritative parenting increased the likelihood of favorable trajectories of migrant children's mathematics development and urban children's literacy and mathematics development. Family SES enhanced migrant children's mathematics development. Family SES contributed to urban children's literacy development through authoritative parenting, yet such a mediating effect was not observed for migrant children. This study highlights the importance of focusing on distinct trajectories of migrant and urban children's literacy and mathematics in improving their school achievement.
