The Discriminative Validity of the Korean Motor-Free Visual Perception Test-4

Abstract

The Motor-Free Visual Perception Test (MVPT) is widely used in rehabilitation settings in Korea, but research on the validity of the MVPT-4, revised in 2015, remains limited. This study aimed to verify the discriminative validity of the Korean MVPT-4 (K-MVPT-4) in healthy individuals and stroke patients. A total of 136 healthy individuals and 81 stroke patients participated were assessed using the K-MVPT-4. Independent t tests and one-way analyses of variance were conducted to examine score differences by the presence of stroke, sex, age, and educational level. Stroke patients scored significantly lower than healthy individuals. Scores also declined with increasing age and lower educational levels, but no significant differences were observed by sex. The findings confirm the discriminative validity of the K-MVPT-4 supporting its clinical applicability as a valid tool for assessing visual perception in stroke patients.

Testing the Korean MVPT-4 to Distinguish Visual Perception in Healthy Adults and Stroke Survivors

Stroke can affect how people perceive what they see, which can make daily activities difficult. This study looked at whether the Korean version of the Motor-Free Visual Perception Test-4 (K-MVPT-4) could accurately tell the difference between healthy adults and those who had experienced a stroke. We tested 136 healthy adults and 81 stroke patients. Results showed that stroke patients scored lower than healthy adults. We also found that older age and lower education levels were linked to lower test scores, but there was no significant difference between males and females. These findings show that the K-MVPT-4 is a useful tool for identifying visual perception difficulties in stroke patients and could help health care providers track recovery and plan better interventions.
