痴呆性高齢者の認知・言語コミュニケーション能力を短時間で測定する「ミニコミュニケーションテスト-MCT」の開発と信頼性・妥当性の検討

To evaluate verbal communication ability in the elderly, we developed a new portable “mini-communication test (MCT)” with 13 sub-scales, which was constructively validated based on 45 items from other reported scales.Clinical reliability and validity were tested in 354 inpatients in a long-term care hospital (81.9±8.3years old) and 124 inpatients (80.39±8.1 years old) and 34 outpatients (76.5±7.0 years old) in Kyorin University Hospital.All patients were evaluated in approximately 7 minutes each. The test-retest correlation coefficient was 0.99. Inter-rater coefficient of variation was 0.107. The Cronbach α value of the test was 0.93. MCT positively correlated with the Barthel Index (r=0.65, p<0.01), Hasegawa Dementia Scale Revised version (r=0.93, p<0.001) and Vitality Index (r=0.66, p<0.01). MCT could be a new tool to assess communication ability in elderly patients with or without dementia.
