Psychometric properties of the Korean Motor-free Visual Perception Test-4 in healthy people
Abstract
This study was conducted to cross-culturally adapt the Motor-free Visual Perception Test 4 (MVPT-4) for use in Korean contexts and examine its psychometric properties. The Korean MVPT-4 (K-MVPT-4) was developed via the process of translation, back-translation, and expert committee review. To establish internal consistency, test-retest reliability, concurrent validity and construct validity of the K-MVPT-4, 295 healthy people aged 10 to 79\u2009years participated in this study. Participants completed the measures for the test-retest reliability on two occasions, 2\u2009weeks apart. After three steps of cross-cultural adaptation, the K-MVPT-4 was revised to improve its alignment with Korean cultural norms. Cronbach’s α for internal consistency was .857 and intra-class correlation coefficient for test-retest reliability was .949. The K-MVPT-4 scores were significantly correlated with those of three motor-reduced subscales of the Korean Developmental Test of Visual Perception-Adolescent (K-DTVP-A) ( r\u2009=\u2009.44–.46, p\u2009<\u2009.01). Participants’ age significantly influenced the K-MVPT-4 scores ( p\u2009<\u2009.001) while their gender did not affect those scores ( p\u2009=\u2009.409). As the age increased, the K-MVPT-4 scores decreased. The findings indicated that the K-MVPT-4 is a reliable and valid test that Korean rehabilitation service providers can use with confidence to assess clients’ visual perceptual abilities.
