A rebuttal to conclusions of a paradox by Wright et al., (2025) and commentary on the limitations of available longitudinal datasets to observe child welfare outcomes

This commentary responds to claims that research shows child welfare services (CWS) involvement harms children’s mental health. We address the misuse of the Fragile Families and Child Wellbeing Study (FFCWS) and similar longitudinal datasets to estimate CWS effects. Severe measurement limitations, extensive misclassification, and inadequate adjustment for maltreatment exposure preclude causal inference. We caution against interpreting associations from these datasets as evidence of CWS‑generated harm. The paper highlights ongoing efforts to correct FFCWS limitations, describes statistical tools that better approximate causal interpretations using administrative data, and advances policy recommendations for improved child maltreatment data collection.
