MAPPING SCHIZOPHRENIC NEGATIVE SYMPTOMS ONTO MEASURES OF THE PATIENTSSPEECH - SET CORRELATIONAL ANALYSIS

We describe a system designed to assess the speech behaviors that info rm clinicians about their patients' negative symptoms. Measures are fo rmed into scales to reflect the patient's Pausing, Speech Rate, and Dy adic Interaction with the interviewer. Using set correlation, we exami ned the associations between the acoustic scales and the clinician's r atings of Flat Affect, Alogia, and Asociality. Over half of the multiv ariance in the clinical scales was accounted for by the acoustic scale s. Unique isomorphisms between the acoustic and rating scales were fou nd for: Dyadic Interaction with Flat Affect; Pause Production with Alo gia; and Rate with Asociality.
