A positive take on schizophrenia negative symptom scales: Converting scores between the SANS, NSA and SDS.

ABSTRACT:

To provide quantitative conversions between commonly used scales for the assessment of negative symptoms in schizophrenia.

Method

Linear regression analyses generated conversion equations between symptom scores from the Scale for the Assessment of Negative Symptoms (SANS), the Schedule for the Deficit Syndrome (SDS), the Positive and Negative Syndrome Scale (PANSS), or the Negative Symptoms Assessment (NSA) based on a cross sectional sample of 176 individuals with schizophrenia.

Results

Between-scale negative symptom ratings were moderately to
