Abstract
Nine clinical psychologists experienced in administering the Wechsler Memory Scale - Revised (WMS-R), and nine inexperienced trainee clinical psychologists scored a videotape of 12 subjects completing the WMS-R Visual Memory test. The subjects were selected to provide a wide range of visual memory scores. Data were analysed for the two subgroups of experienced and inexperienced raters and for the entire group of 18 raters. Inter-rater reliability was extremely impressive in all three analyses, with Kendall's coefficient of concordance always exceeding .92, (p less than .001). No significant difference emerged when experienced and inexperienced raters were compared. The results suggest that the WMS-R visual memory test has acceptable inter-rater reliability for both experienced and inexperienced raters. Recommendations are made regarding improving this reliability even further.
