It takes a village: Fixed-effects analysis of neighborhood collective efficacy and children's development.

BACKGROUND: Previous studies suggest that neighborhood social capital is associated with children's mental health. The purpose of this study was to examine the association between neighborhood collective efficacy and children's psychosocial development.

METHODS: We used data on children and their parents (n = 918) who were part of the Japanese study of Stratification, Health, Income, and Neighborhood (JSHINE) from 2010 to 2013 (wave 1 and wave 2). Households were recruited from the Tokyo metropolitan area through clustered random sampling. Changes in children's psychosocial development (assessed using a child behavioral checklist) between waves 1 and 2 were regressed on parents' perceptions of changes in neighborhood collective efficacy (social cohesion and informal social control).

RESULTS: Change in perception of neighborhood social cohesion was inversely associated with change in child total problems (β = -0.22; 95% confidence interval [CI]: -0.37 to -0.001; effect size d = -0.03). Change in perceptions of neighborhood informal social control was inversely associated with change in children's externalizing problems (β = -0.16; 95% CI: -0.30 to -0.03; d = -0.02).

CONCLUSIONS: The results of these fixed-effects models suggest that strengthening neighborhood collective efficacy is related to improvements in child psychosocial development.
