摘要

The present study reported preliminary normative data on the performance of the Loewenstein Occupational Therapy Cognitive Assessment-Second Edition (LOTCA-II) performances by a group of 137 native Chinese-speaking persons without disabilities stratified on age (30-37, 40-49, 50-59, 60-69, and 70-79 years) and education (0-6, 7-9, 10-12, and 13-16 years). Forty-five patients with brain damage (stroke and traumatic brain injury) recruited from a medical center and 4 regional hospitals in southern Taiwan participated in the study. Non-disabled people were administered the LOTCA-II only, whereas patients with brain damage were given the LOTCA-II and Mini-Mental State Examination (MMSE). The results showed that normal group performed significantly better than the patients with brain damage across LOTCA-II subtests (Wilks' lambda=0.44, F=14.66, df=12, 348, p=0.000). Motor praxis, visuomotor organization, and spatial perception were the three subtests with highest standardized canonical discriminant function coefficients that significantly discriminated between the normal and patient groups, with an overall accurate classification rate of 89.6%. Age and education effects were observed in the normal group, and a demographically corrected regression equation as well as standard error estimates were generated accordingly from multiple regression analysis. A significant discrepancy was defined as the difference between scores obtained for the LOTCA-II equal to or greater than 2 standard errors of the estimate below the expected LOTCA-II scores, using a standard regression procedure that accounts for the effects of age and education. 60% of the patients were categorized as having cognitive impairment using the above regression procedure, whereas cognitive impairment was identified in 59% of brain-damaged group using MMSE cutoff score of 26/27. The agreement Original rate in classifying patients into two groups, those with and without cognitive impairment, was moderate (kappa=0.48). Our results should help improve interpretation of LOTCA-II performance in patients with brain damage.
