Spontaneous movements of preterm-born infants predict social competence and self-esteem at early school age: The mediating role of motor skills and maternal emotional availability.

= 13.75). Children's motor skills were evaluated using a standard test, and mothers' emotional availability was observed during mother-child play interactions. Mothers and teachers reported children's social competence, and teachers reported children's self-esteem. After controlling for child gender, gestational age at birth, and mothers' education level, the results indicated that atypical spontaneous movements in infancy predicted lower social competence and self-esteem in childhood. Motor skills in childhood mediated both links, and mothers' emotional availability mediated the link to social competence. These results highlight the significance of motor functioning in infancy and childhood for the socioemotional adjustment of preterm-born children.
