Abstract
OBJECTIVE: Different studies have revealed mixed findings regarding the relation between maternal prenatal stress or anxiety (MPSA) and early child cognitive outcome. Different methodological considerations may be linked to the absence of clear support for this hypothesized link. The purpose of this article was to conduct a meta-analysis of this relation while considering the following as potential moderators: (1) pregnancy trimester during which MPSA was assessed, (2) type of MPSA assessment (life events, pregnancy related, subjective assessments), and (3) research design (retrospective or prospective). Other moderators were also examined: child age at assessment and the year of publication. METHOD: Eleven studies were identified (N = 5903) that examined the relation between MPSA and early child cognitive outcome. RESULTS: A small effect size of r = -.05 was found for this relation. The effect size varied across studies and was significantly moderated by the manner in which MPSA was operationalized (events, subjective assessment of stress or pregnancy-related stress or anxiety) and by whether MPSA assessment took place before or after infant birth. Greater relations to child cognitive outcome were found for postnatal event-based indicators of MPSA. CONCLUSION: The relation between MPSA and child cognitive outcome seems to be present, but low. Moreover, it is affected by the specific choices made by researchers in the manner in which constructs are operationalized.

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 it
