Characterization of depressive syndrome in schizophrenic outpatients
Bibliographic record
Abstract
OBJECTIVE: The authors carried out a cross-sectional study with the aim of characterizing and describing depressive pictures in schizophrenic patients seen at the Psychiatry Outpatient Clinic of the Federal University of Pernambuco (HC-UFPE). The patients had the diagnosis of schizophrenia confirmed on the basis of the operating criteria of the DSM-IV. METHODS: Those who where in the period of stabilization of the clinical picture were selected for the study defined according the following criteria:the last psychotic episode must be happened two months before at least, and during this period the alterations of the antipsychotics doses had been lower than 5 mg of haloperidol or equivalent doses of others neuroleptics. A total of one hundred and four patients took part. Following the identification of the depressive symptoms using the Calgary Depression Scale for Schizophrenia (CDSS), thirty-one patients (29.8%) fulfilled the diagnostic criteria described in the DSM-IV. Of these, 22.1% had the diagnosis of major depression and 7.7% of minor depression according the DSM-IV. Two groups were constituted: Group A, schizophrenics with a depressive syndrome, and Group B, schizophrenics without such a syndrome. An assessment was made of the distribution of the symptoms of the CDSS scores in both groups, the sociodemographic, clinical and therapeutic variables in relation to the frequency of the depressive syndrome, and the patients clinical course. For the investigation of certain clinical features, the following tools were used: problem list (psychosocial stressors) contained in axis IV of the DSM-IV intended to detect the presence of factors triggering the initial episode of schizophrenia and the Global Assessment of Functioning (GAF -- Axis V -- DSM-IV) to characterize the current functioning of the patients. CONCLUSIONS: The results obtained allowed the authors to draw the following conclusions: all the items that comprise the Brazilian version of the CDSS were statistically significant in characterizing the depressive syndrome; a comparison of the sociodemographic and therapeutic variables revealed no statistically significant differences between the two groups, and this was also the case with the majority of the clinical features. Statistically significant differences, however, were found in relation to the greater frequency of life events (psychosocial stressors) in triggering the first episode of schizophrenia and the higher incidence of affective disorders antecedents in family members (first and second degree) among the depressed patients. The mean duration of the depressive syndrome during follow-up of the patients was 5.30 months. The patients in whom there was a recurrence of the psychotic episode presented a delusional-hallucinatory clinical picture. This study seeks to contribute to the inclusion of the Postpsychotic Depressive Disorder (PSD) of Schizophrenia (DSM-IV), in the group of Schizophrenic Disorders.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
