Are children and adolescents in foster care at greater risk of mental health problems than their counterparts? A meta-analysis
Bibliographic record
Abstract
This meta-analysis aims at comparing mental health problems of children in foster care to those living with their biological parents while taking in consideration different protective and risk factors. Across 41 studies with a total of 72 independent effect sizes, a significant but small effect size was found between foster care placement and psychopathology (d = 0.19). Children in foster care showed higher levels of psychopathology compared to those from community samples or matched/at-risk samples. They were as likely to show mental health problems as maltreated children living with their biological parents or children from clinical samples. Results showed that foster children’s mental health problems also varied as a function of type of placement and study methodological characteristics. Being placed in kinship care, longer stay in the same foster home and fewer placement disruptions, all acted as protective factors limiting mental health problems of children in foster care.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
