NEGATIVE SYMPTOMS AND VISUAL BEHAVIOR IN DSM-III-R PROGNOSTIC SUBTYPES OF SCHIZOPHRENIFORM DISORDER

Eighteen male patients with a DSM-III-R diagnosis of schizophreniform disorder were rated on the Scale for the Assessment of Negative Symptoms and their visual behavior during interview was recorded through an ethological technique. Affective flattening, alogia and the global severity of the negative-symptom syndrome were found to be more prominent among poor-prognosis patients. In addition, compared with patients with good prognostic features, poor-prognosis patients showed a pattern of visual behavior (less eye contact and more eye closures) suggesting poor rapport with the interviewer. The results demonstrate that cross-sectional phenomenology of patients with DSM-III-R schizophreniform disorder shows differences in important clinical domains, such as negative symptoms and capacity to establish and maintain social interaction.
