Validity and Reliability of the “Visual Object and Space Perception Test” in Turkish

Aim: Although many tests evaluating visual perceptual impairment have been developed in the clinic, it is seen that the tests within Turkish validity and reliability are insufficient. Visual Object and Space Perception (VOSP) Test, which evaluates visual and spatial perception separately, is distinguished from other visual perceptual tests as a sensitive battery. In our study, it is aimed to analyze Turkish cultural adaptation, validity, and reliability of VOSP Test, which evaluates visual-spatial functions in stroke survivors and healthy individuals. Methods: Twenty-seven stroke patients with right hemisphere lesions and 54 healthy individuals were included in our study. Criterion validity method has been used to examine the validity. Internal consistency, Cronbach alpha and test-retest methods have been used for the reliability of the test. Results: Eighty-one participants [45 (55.6%) female] have been included in our study. The mean age was 46.04±14.74 years. Turkish version of the VOSP test has been found to be sufficient and reliable according to the Cronbach Alpha Coefficient (0.923). Conclusion: In the light of the findings of our study, it has been concluded that the Turkish version of the VOSP Test is a valid and reliable measurement tool and that this test can be benefited by scientific and clinical studies.
