Abstract
BACKGROUND/AIMS: Researchers have shown interest in the association between anhedonia and depression in schizophrenia. The aim of the current study was to investigate the relationship between physical and social anhedonia with depression in a sample of inpatients with schizophrenia in the acute phase of their illness. METHODS: Sixty-two patients with acute schizophrenia consecutively admitted at the Eginition Hospital, Department of Psychiatry, University of Athens were assessed using the revised Physical Anhedonia Scale, the revised Social Anhedonia Scale and the Calgary Depression Scale for Schizophrenia. RESULTS: The Calgary Depression Scale for Schizophrenia score correlated with both physical anhedonia and social anhedonia ratings. The revised Social Anhedonia Scale score significantly correlated to self-depreciation, guilty ideas of reference, pathological guilt, early wakening, suicidality and observed depression. The revised Physical Anhedonia Scale score significantly correlated with depressive mood, self-depreciation, pathological guilt and observed depression. Self-depreciation, pathological guilt and observed depression were correlated with both social and physical anhedonia. CONCLUSION: Depression in schizophrenia and anhedonia may overlap, and it could therefore be difficult to clinically differentiate them, especially in acute schizophrenia patients.

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
