title: Inpatient Memory Impairment Scale: a cross-validation and extension study.
abstract: The psychometric properties of the Inpatient Memory Impairment Scale (IMIS), a 10-item behavioural rating scale for assessing hospitalized amnesiacs, were investigated using matched groups of 18 amnesiacs, 20 chronic alcoholics, and 20 psychiatric patients. The scale was found to have a high degree of internal consistency and interrater reliability when two raters are used and to correlate significantly with a range of memory tasks. The IMIS was found to discriminate amnesiacs from chronic alcoholics and amnesiacs from psychiatric patients, which extends the findings of previous studies that used this scale. It is concluded that the IMIS has encouraging psychometric properties that have been replicated in this study and that the development of ecologically valid behavioral measures of cognitive deficit represents a promising direction for future research.
