Abstract

fetched live from OpenAlex

Childhood adversity describes a range of adverse experiences, including sexual, physical, and emotional abuse, neglect, and other adverse life events that have occurred during childhood 1 . It is associated with an elevated risk of schizophrenia 1 , 2 . Studies of individuals with childhood adversity and schizophrenia report lower intelligence quotient (IQ) scores 3 , 4 . A population twins study found that children exposed to domestic violence had lower IQs than unexposed children, regardless of underlying genetic factors 3 . Meanwhile, another study on 216 twins including monozygotic (MZ) and dizygotic (DZ) probands pairs and MZ/DZ healthy controls showed that schizophrenia polygenic risk score (PRS) and childhood trauma predict schizophrenia vulnerability 2 . Given that schizophrenia has also continuously been linked to lower IQ levels as two meta-analysis studies reported that the mean IQ scores of individuals who subsequently develop schizophrenia are lower than those of healthy comparison individuals years before the beginning of psychotic symptoms 5 , 6 , the impact of childhood abuse on cognition may constitute a step in the developmental process leading to psychosis 7 . Low IQ in patients with schizophrenia has been identified as a predictor of poor social and clinical outcomes 8 . Fundamental questions that are highly relevant to our understanding of schizophrenia, and as yet unresolved, are whether the effect of childhood adversity on IQ is influenced by brain volume or genetic variation and if so, does the effect of these factors differ between patients with and without treatment-resistant schizophrenia (TRS)?

Not 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.
