Scholarcy highlights

  • The Mattis Dementia Rating Scale, a widely used dementia screening instrument, generates five subscale scores in the areas of Attention, Initiation-Perseveration, Construction, Conceptualization, and Memory
  • Subject performance on the five DRS subscales was correlated with performance on five well-validated neuropsychological criterion measures using Pearson r and stepwise regression
  • Each DRS subscale emerged as the Step 1 predictor of its assigned criterion measure, with the exception of DRS CN, which was the Step 2 predictor
  • The results suggested that overall the DRS subscales are valid measures of their respective constructs and have value for both clinical and research purposes in mild and moderate dementia
