Estimates of interrater reliability for the Logical Memory subtest of the Wechsler Memory Scale-Revised.

This study was undertaken to investigate the interrater reliability of the Logical Memory subtest of the Wechsler Memory Scale-Revised under two conditions. In the first condition, raters applied standard WMS-R scoring for Logical Memory to written transcripts of subjects' recall. In the second condition, raters were instructed to listen to and record subjects' responses before applying the scoring criteria. Responses from 32 undergraduate university students were scored by three independent judges with professional experience in WMS-R use. Responses were analysed to generate estimates of interrater reliability that could be compared to those provided in the WMS-R manual (Wechsler, 1987). The results provide independent confirmation that the standard scoring procedure for Logical Memory is highly reliable when applied by trained clinicians.
