Abstract

Objective: The purpose of this study is to conduct a preliminary research for the development of a Performance-Based Cognitive Function Test (PCFT) to screen the elderly for cognitive function impairment, and examine the reliability and validity of the test.
Methods: A draft version of the Performance-Based Cognitive Function Test (PCFT) was developed and utilized in nine healthy elderly individuals. In order to verify its reliability, we analyzed the internal consistency of the PCFT. In order to verify the concurrent validity of the PCFT, this study analyzed the correlation between motor-cognitive dual task assessments and the Korean version of the Mini-Mental State Examination (MMSE-K).
Results: The internal consistency of the PCFT for motor and cognitive tasks was 0.871 and 0.959 (Cronbach’s α), respectively. Concurrent validity of the PCFT, which was performed through motor-cognitive dual task assessments, ranged from 0.755 to 0.964 (Spearman’s rho statistic, p < 0.05). In addition, correlation between the cognitive assessment tool and the MMSE-K ranged from 0.849 to 0.943 (p < 0.01).
Conclusion: This study verified, and established the reliability and validity of the PCFT. Further studies are required to examine other psychometric properties in a modified PCFT, for screening cognitive function impairments in the elderly.
