Abstract

fetched live from OpenAlex

AIM: Schizophrenia is a leading cause of disability worldwide; early detection and intervention are critical. Early in their illness, individuals at clinical high-risk (CHR) for psychosis have subthreshold psychotic symptoms that are often derogatory and self-directed. We hypothesized that CHR participants with negative self-reference (NSR) as a component of subthreshold psychosis would also have higher levels of social anxiety and depression, lower self-esteem and lower social/role/global functioning as compared with CHR participants without NSR. METHODS: One hundred and sixty-eight participants from the National Institute of Mental Health (NIMH) funded Regroup Cognitive Behavioural Social Skills Training (CBSST) study were included. Clinical vignettes that included the Scale of Psychosis-Risk Symptoms were coded categorically to indicate whether NSR was present. t-tests were used to determine the association between NSR, symptom, and functional measures. RESULTS: Participants with NSR demonstrated significantly more social interaction anxiety (p < .001), negative beliefs about the self (p ≤ .001), defeatist beliefs (p < .05), depressive symptoms (p < .05) and positive symptoms (p < .005). There were no significant differences in social self-efficacy, positive or negative beliefs about others, positive beliefs about the self or psychosocial functioning between the two groups. CONCLUSIONS: Clinically significant differences were found between CHR participants with and without NSR, suggesting that this may be a useful factor to identify and address. Follow-up studies are needed to determine whether NSR responds to CBSST and whether or not its resolution would be associated with improvement in other symptom domains.

Not 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.
