PSYCHOMETRIC EQUIVALENCE OF THE HASEGAWA DEMENTIA SCALE REVISED WITH THE MINI-MENTAL-STATE-EXAMINATION IN STROKE PATIENTS

Responses to the Hasegawa Dementia Scale-Revised and the Mini-Mental S tate Examination were examined for 49 stroke patients to investigate t he psychometric equivalence between the two tests. Pearson product-mom ent correlation and Spearman rank-order correlation between the two te sts were 0.87 and 0.78. Each test's scores significantly correlated wi th the Full Scale IQs on the Wechsler Adult Intelligence Scale-Revised : 0.61 for Hasegawa's Dementia Scale and 0.69 for the Mini-Mental Stat e Examination. These values indicate that the two tests are judged com parable measures for screening cognitive impairment in stroke patients .
