Mori S, Osawa A, Maeshima S, Ozaki K, Sakurai T, Kondo I, Saito E. Clinical examination of reliability/ validity of scoring methods for Cube-Copying Test (CCT). Jpn J Compr Rehabil Sci 2014; 5: 102-108. Objective: Various scoring methods for the CubeCopying Test (CCT) have been assessed for their validity, but few have been examined for reliability. Additionally, a comparison of multiple scoring methods applied to an identical group of patients has not been reported to date. The present study examined both the reliability and validity of multiple scoring methods and their role in the evaluation of spatial cognitive function. Method: Thirty-three patients who visited the Medical Center for Dementia at our hospital were included in the study. The Cube-Copying Test was independently scored by two raters using two different scoring methods. Results: Both scoring methods showed significant inter- and intra-rater reliability. The assessment of criterion-related validity showed a significant correlation with Raven’s Colored Progressive Matrices and Frontal Assessment Battery, demonstrating that the CCT reflects visual cognitive functioning and executive functioning. The CCT also showed a significant correlation with education years, suggesting that the CCT scores are more affected by years of education than by age or duration of illness. |
