Converging Evidence of a Specific Vulnerability of Young Boys to Parental Childhood Trauma
Bibliographic record
Abstract
Objective Childhood trauma is common among parents and can have intergenerational effects. Preliminary evidence suggests that young boys may be more vulnerable to maternal childhood trauma than girls. This finding needs to be replicated, and it remains to be determined whether it also applies to paternal childhood trauma. The current study aims to examine the associations between parental childhood trauma and 3 indicators of early functioning (general development, socioemotional development, and temperament) in offspring and to assess the moderating role of child sex. Method Childhood trauma was assessed during pregnancy in 3 community samples of women (N = 143; N=195; N=216) and postnatally in 1 community sample of fathers (N = 165). Child functioning was assessed using parental reports of child development and temperament between 6 and 38 months postnatal. Regression-based moderation analyses were conducted. Results Significant associations between parental childhood trauma and adverse child outcomes were observed in all samples. A moderating role of child sex was supported in 3 of the 4 samples, all indicating greater vulnerability to parental childhood trauma among boys. Conclusion These findings suggest that maternal and paternal childhood trauma are associated with poorer functioning in infants and toddlers, but only in boys. This has implications for personalized preventive interventions with parents exposed to childhood trauma. These results call for replication with large and diverse samples including biological measures and observational measures of child development. Plain language summary This study utilized three samples of mothers and one of fathers from Quebec, Canada to examine the associations between parental childhood trauma and early childhood functioning. In three of the four samples, young boys exhibited increased vulnerability to parental childhood trauma in comparison to girls. These findings must be replicated to consider their potential for personalized preventive interventions for male offspring of parents exposed to childhood trauma.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
