Maternal Reports to the Child Protection System: A Longitudinal Analysis of Multiple Children.

Child maltreatment can affect multiple children in a family, yet its occurrence and chronicity has been often assessed by focusing on a single child. Although this approach provides valuable insights, considering the experiences of all children in a family may provide a more complete understanding of maltreatment dynamics. Using linked birth and child protection system (CPS) records from California, we analyzed 20 years of data on 194,514 first-time mothers to document the prevalence, timing, and chronicity of maternal CPS reporting across multiple children. Mothers were categorized by the number of live childbirths: one (25.7%), two (36.2%), three (20.9%), and four or more (17.2%). Overall, 33.0% of mothers were reported to CPS, increasing from 18.5% for mothers with one child to 63.1% for those with four or more children. For mothers with two or more children, more than 70% experienced an initial CPS report only after the second child's birth. Our findings have implications for understanding the dynamics of maternal reports to CPS, emphasizing the need for lasting and family-focused interventions.
