Abstract

Objective
The study’s aim was to evaluate the validity of the Korean version of the University of California San Diego Performance-based Skills Assessment, Validation of Intermediate Measures (K-UPSA-2-VIM) in patients with dementia (D), mild cognitive impairment (MCI), and cognitive normal control group (CN).
Methods
Study participants were 25 patients with D, 43 patients with MCI, and 111 controls with CN group, respectively. For cognitive assessment, Mini Mental State Examination, Consortium to Establish a Registry for Alzheimer’s Disease neuropsychological battery, and Clinical Dementia Rating were used. For functional assessment, Barthel-Activities of Daily Living, Instrumental Activities of Daily Living, Dementia Screening questionnaire, and K-UPSA-2-VIM were used.
Results
Statistically significant differences were observed in all subdomains and total score of the K-UPSA-2-VIM among three cognitive groups. K-UPSA-2-VIM demonstrated 75.7% of sensitivity and 65.1% of specificity, with an area under the curve (AUC) of 0.731 (95% confidence interval [CI]: 0.641-0.821, p<0.001) in discriminating between CN and MCI groups. In discriminating between MCI and D groups, 76.7% of sensitivity and 64.0% of specificity, with an AUC of 0.706 (95% CI: 0.580-0.833, p=0.005) were demonstrated.
Conclusion
The K-UPSA-2-VIM is useful to evaluate activities of daily living function in Korean patients with D and MCI.
