Using a three-wave longitudinal survey conducted in 815 households in rural Western China, this study aims to examine the association between parental self-perception and early childhood development and the mediation effect of parental investment on the association between parental self-perception and child development when the sample children are at different ages in the early childhood (18–30, 22–36, and 49–65 months). The results demonstrate that parental self-perception are positively and significantly associated with child social-emotional development in all three ages of childhood (from 18 to 65 months). Positive and significant association between parental self-perception and child cognitive development is found in the ages from 22 to 65 months. In addition, findings of this study show that parental investment plays a mediating role in the association between parental self-perception and child cognitive development. The study calls on policymakers to help to strengthen parental self-perception and parental investment related to early childhood development, which should result in better child development in rural China.

Background: Social-emotional development during the first three years of life is associated with later social-emotional development and cognitive development. In rural China, research has found large shares of children under age three are developmentally delayed, yet little is known about the paths of social-emotional development before age 3 or how developmental paths predict later social-emotional skills and cognitive skills. 

Aims: To investigate the paths of child social-emotional development during ages 0–3 and examine how different paths predict social-emotional development and cognitive development at preschool age. 

Methods: Three waves of longitudinal panel data from 1245 children in rural Western China was collected. Child social-emotional development was measured by the Ages and Stages Questionnaire: Social-Emotional. Child cognitive development was measured by the Bayley Scales of Infant Development and by the Wechsler Preschool and Primary Scale of Intelligence-Fourth Edition. Four paths of child social-emotional development were classified: “never” social-emotionally delayed; “persistently” social-emotionally delayed; “improving,” or “deteriorating.” 

Results: 331 (27%) were never social-emotionally delayed; 373 children (30%) were persistently social-emotionally delayed; 149 children (12%) experienced improving social-emotional development; and 392 children (31%) experienced deteriorating social-emotional development. Children who were never social-emotionally delayed or who were on an “improving” path had higher social-emotional development at preschool age (p < .01). Children who were persistently social-emotionally delayed (p < .5) and on a deteriorating path (p < .01) had lower social-emotional development at preschool age. Children on the persistently delay path also were shown to have lower levels of cognitive development at preschool age (p < .01). 

Conclusions: Different paths of child social-emotional development before age 3 are associated with different social-emotional and cognitive development at preschool age.
