Test-retest and inter-rater reliability were assessed in a sub-sample of 30 patients.

Therefore, the model obtained with four factors showed good final data adjustment, namely: Each category contains five different ratings that evaluate positive, negative, depressive, cognitive and global symptoms, and a seven-point ordinal scale bpra applied to evaluate these categories. For decades, many efforts have been performed to characterize the clinical symptomatology of schizophrenia.

Factor analysis studies using the BPRS as their instrument and in a population with not-specified refractoriness, the symptom “disorganization of thought” has been grouped to the factor “positive symptoms”, as shown in Overall and Klett, 5 Guy 9 and Zuardi et al 25 or grouped to the factor “negative”, as seen in Acorn.

The results of this study replicate the factors “positive” and “negative” and evidence that they are found in all studies of factor analysis among schizophrenic patients who are responsive and not-responsive to typical neuroleptics using the BPRS or other instrument for psychopathological measure.


The interview was conducted by the psychiatrist and at the end both filled out independently their scores. The debate whether the symptom “disorganization” pertains to the psychotic dimension factor “positive” or is an independent dimension is important as the concept of treatment resistance has been associated with that of persistence of positive symptoms since nearly one decade.

Interrater reliability was assessed by comparing the ratings of each of the CGI-SCH dimensions administered by two psychiatrists to the same patient, and analyzed using intraclass correlation coefficients ICC.

Concurrent validity and sensitivity to change were assessed by comparison with the Positive and Negative Syndrome Scale, which is considered b;rs gold standard tool to evaluate patients with schizophrenia.
