The 10-item Treatment Response Scale (TRS) was used to rate the charts
of schizophrenic inpatients for prior response to neuroleptic treatment.
Interrater reliability, interitem agreement, and agreement of each item
with total TRS scores were good. The validity of the TRS was assessed
against changes in independent measurements with the Brief Psychiatric
Rating Scale. The results indicate that findings from a systematic chart
review correlate substantially with clinical assessment of response.
