Abstract

Toxic stress caused by child maltreatment can lead to adverse mental health outcomes in later life, yet unmeasured confounding has been a major issue in many previous studies. To examine the association between child maltreatment and resilience and behavior problems among early elementary school-age children, we used data from a population-based longitudinal survey targeting all first-grade children in 2015 in Adachi City, a ward in Tokyo, Japan. Children whose caregivers provided valid responses during the 2015 (first grade; ages 6–7 years), 2016 (second grade; ages 7–8 years), and 2018 (fourth grade; ages 9–10 years) waves of the study were included in the analysis (n = 2,920). Fixed-effects regression models revealed that child maltreatment was inversely associated with resilience (β = −0.89, 95% confidence interval (CI): −1.05, −0.72) and prosocial behavior (β = −0.03, 95% CI: −0.05, −0.003) and positively associated with behavior problems (β = 0.32, 95% CI: 0.27, 0.37) over 4 years of follow-up (2015–2018), after controlling for all time-invariant confounders and measured time-varying confounders and survey year. These associations were consistent across sex. Child maltreatment may hamper the development of resilience and prosocial behavior and induce behavior problems in early elementary school children over time. Future researchers should identify modifiable protective factors for better mental health among maltreated children.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
