Abstract
BACKGROUND: The influence of severe psychopathology on alexithymic features has been poorly studied. This study aimed at investigating whether alexithymia is affected by the presence of psychosis and the severity of psychopathology. SAMPLING AND METHODS: 199 consecutive adult psychiatric inpatients, 60 of whom received a Structured Clinical Interview for DSM-IV Axis I diagnosis of psychotic disorder, were administered the 20-item Toronto Alexithymia Scale (TAS-20) and the 24-item Brief Psychiatric Rating Scale (BPRS). A random sample of 50 patients was reassessed at discharge. For all analyses, the Holm-Bonferroni correction was applied when appropriate to account for multiple testing. RESULTS: The TAS-20 showed good internal consistency, acceptable relative stability, and good absolute stability both in patients with and without a psychotic disorder. Internal consistency and relative stability were higher in nonpsychotic than in psychotic patients. Mean TAS-20 score at admission did not differ between psychotic and nonpsychotic patients, and the TAS-20 score showed only a nonsignificant correlation (rho = 0.26) with BPRS score. Alexithymia at discharge was mostly explained (60%) by alexithymia at admission, while it was only modestly explained (4%) by BPRS scores at admission and discharge, with the latter being the only significant predictor. Changes in BPRS scores between admission and discharge explained a nonsignificant proportion (16%) of changes in TAS-20 scores and a moderate (21%) proportion of changes in difficulty identifying feelings. CONCLUSION: Despite some limitations, these findings suggest that the severity of psychopathology and the presence of a psychotic disorder only modestly influence alexithymic characteristics, and that the TAS-20 may provide a reliable assessment of alexithymia in patients with severe psychopathology, except the most severely impaired ones.

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
