Correlation of the Hamilton and Carroll Depression Rating Scales: a replication study among psychiatric outpatients.
The Carroll Depression Rating Scale (CRS) was developed as a self-administered variant of the widely used Hamilton Depression Rating Scale (HDRS). This study is a replication. The CRS and HDRS total and item correlations are compared for a sample of 64 outpatients. The CRS is shown to be a reliable and convenient alternative to the HDRS, suitable for routine office practice.
