A Developmental Pathway from Early Inhibitory Control to Social Connectedness.

Social connections are critical for mental and physical health; however, the developmental pathways to children's social connectedness outcomes are not well understood. This study examined the pathways from children's inhibitory control at 4 years to two social connectedness outcomes - loneliness and friendship quality at age 10 - through behavioral problems at age 7. As part of a longitudinal study (N = 291, 54% girls), children's inhibitory control was assessed via a Go/No-Go task when children were 4 years old. Mothers reported on children's behavioral problems at ages 4 and 7 years. Children reported on their friendship quality and loneliness at ages 7 and 10 years. Greater inhibitory control at 4 years predicted lower behavioral problems at 7 years, which in turn predicted better friendship quality and lower loneliness at 10 years. Indirect effects from inhibitory control at 4 years to loneliness and friendship quality at 10 years via behavioral problems at 7 years were significant. Findings suggest that inhibitory control in early childhood may play a key role for the development of social connectedness in middle childhood via its impact on children's behavioral problems.
