title: Rating scale for the assessment of communication disorders in schizophrenics.
abstract: Taking up the Bleulerian view of a clinical description based on a pathogenic model, we propose a rating scale for the assessment of communication disorders in schizophrenic patients. The scale consists of clinical items that could be the direct expression of the three hypotheses of cognitive dysfunction which have been postulated to explain communication dysfunction in these patients. We assessed the frequency of the 16 items in the scale in a total of 80 subjects (43 schizophrenic subjects, ten manic subjects, 17 depressive subjects and ten normal control subjects). The results of this study showed that this item schedule was specific to schizophrenic patients and, in particular, could statistically significantly discriminate schizophrenic patients from psychotic patients with affective disorder. The methodological qualities of the scale were explored and proved accurate, except for the reliability which is too low for some items and the item-to-total correlation which is too low for one item of the scale.
