Pre-Separation Mother–Child Relationship and Adjustment Behaviors of Young Children Left Behind in Rural China: Pathways Through Distant Mothering and Current Mother–Child Relationship Quality

In China, some rural parents do not live together with their children because they migrate to urban regions for work, and therefore they sometimes use a mobile phone in parenting their left-behind children (LBC), who are living with grandparents. This study used a serial mediation model to test the mediating roles of distant mothering and post-separation mother-child relationship quality in the link between recalled pre-separation mother-child relationship quality and social-emotional adjustment of 3-to-6-year-old LBC living in a rural context in China. Cross-sectional questionnaire data were collected from 185 triads, consisting of grandparents (rating child adjustment), migrant mothers (rating mother-child relationship qualities and distant mothering), and preschool teachers (rating child adjustment). The results showed that pre- and post-separation relationship qualities were positively related to each other and to positive distant mothering. There were no serial mediating effects, but a full individual mediating role of post-separation relationship quality and positive distant mothering was identified for the link between child prosocial behavior and externalizing problems, respectively. Despite the general decline in mother-child relationship quality after separation, mothers who perceived a higher quality of the pre-separation mother-child relationship showed a more cohesive relationship with their LBC, which might increase the prosocial behavior of the children. Additionally, a higher quality of the pre-separation relationship was associated with more distant mothering of positive characteristics, which went together with fewer children externalizing problems. These findings highlight the importance of a continuous high-quality mother-child bond and favorable maternal parenting practices in digital interactions for separated families.
