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.

Amaç: Klinikte görsel algısal bozukluğu değerlendiren birçok test geliştirilmiş olmasına rağmen Türkçe geçerlilik ve güvenilirliği bulunan testlerin yetersiz kaldığı görülmektedir. Görsel ve uzaysal algıyı ayrı ayrı değerlendiren “Visual Object and Space Perception (VOSP/Görsel Nesne ve Uzaysal Algı) Testi” hassas bir batarya olarak diğer görsel algısal testlerden ayrılmaktadır. Çalışmamızda inme geçiren bireyler ve sağlıklı bireylerde görsel-uzaysal işlevleri değerlendiren VOSP Testinin Türkçe kültürel adaptasyon, geçerlilik ve güvenilirlik analizinin yapılması amaçlanmıştır.

Yöntem: Çalışmamıza sağ hemisfer lezyonuna bağlı inme tanısı almış 27 hasta birey ve 54 sağlıklı birey dahil edildi. Geçerliliğin incelenmesinde kriter geçerliği yönteminden yararlanıldı. Testin güvenilirliği için; iç tutarlılık, Cronbach Alpha ve test-tekrar test yöntemlerine başvuruldu.

Bulgular: 81 katılımcı [45 (%55,6) kadın] dahil edildi. Yaş ortalaması 46,04±14,74 idi. VOSP testinin Türkçe versiyonu Cronbach Alfa katsayısına göre yeterli ve güvenilir bulundu (ICC=0,923).

Sonuç: Çalışmamızın bulguları ışığında, VOSP Testinin Türkçe versiyonunun geçerli ve güvenilir bir ölçme aracı olduğu, bilimsel ve klinik çalışmalarda bu ölçekten yarar sağlanabileceği sonucuna ulaşıldı.
