Abstract

Aim: The main purpose of this study, a test of Clock Drawing (CDT), classified also as a neuropsychological device is made suitable and standardize for Turkish adults and/or elderlys. The screening test is called Clock Drawing (4 point scoring method) measured to executive functions like planning, organization, reconstruction.Materials and Methods: The standardization study was carried on 404 participants (204 female and 200 male). The 50 and over year old participants from state and private institutions or retired this instutions. The research design of standardization study involved age (7 levels), sex (2 levels) and education (3 levels).Results: ANOVA revealed a significant main effect of age and education and interection effect of age and education. Test-retest reliability of the total score of CDT was found .88, inter-rater reliability was found .74. 20 were diagnosed to be Alzheimer type dementia (ATD) and 20 were evaluated as normal controls. The CDT scores were analysed by age groups for conguirent validity.Conclusion: This study provides normative data for a psychometric tool that reliably measures the executive functions in 50 year and over Turkish elderlys. This study showed that four point version of CDT has reliability and validity in Turkish elderly.

Özet

Amaç: Araştırmanın amacı, bir nöropsikolojik tarama testi olan Saat Çizme Testi'nin (SÇT) (dört puanlık versiyon) ülkemiz kültürü için 50 yaş ve üzeri örneklemde standardizasyon çalışmasını yapmaktır. SÇT'i (4 puan yöntemi) planlama, organizasyon, yeniden yapılandırma gibi yönetici işlevleri ölçen bir tarama testidir. SÇT'nin öncelikle norm değerleri belirlenmiş, ardından geçerlik ve güvenirlik çalışmaları yapılmıştır.Yöntem ve Gereç: Norm belirleme çalışmasında yeralan toplam 404 sağlıklı yaşlı katılımcı (204 kadın, 200 erkek) kamuya ait ve özel kurum ve kuruluşların çalışanları ile emeklileri arasından sağlanmıştır. Çalışmanın deseni yaş (7 düzey), cinsiyet (2 düzey) ve eğitim durumu (3 düzey) değişkenlerini içermektedir.Bulgular: ANOVA sonucunda yaş ve eğitim değişkenlerinin SÇT puanları üzerindeki temel etkisi anlamlı düzeyde bulunmuştur. Ayrıca, yaş ve eğitim düzeyi değişkenlerinin ortak etkisi de anlamlı düzeydedir. SÇT'nin test-tekrar test tekniği ile hesaplanan güvenirliği .88, yargıcılararası güvenirliği .74 olarak hesaplanmıştır. Kurultu geçerliği çalışmaları kapsamında yaş grupları karşılaştırılmıştır.Sonuç: Bu çalışma ile 50 yaş ve üzerindeki Türk yaşlı örnekleminde yürütücü işlevlere duyarlı bir psikometrik aracın normatif verisi toplanmış, geçerlik ve güvenirlik değerleri belirlenmiştir.
