Reliability of Criterion-Dependent Measurement Tools According To Generalizability Theory: Application in The Case of Eating Skills

Öz

Applied behavioral analysis is one of the most frequently utilized to help students with mental disabilities develop skills of living independently. Applied behavior analysis is based on direct measurement with criterion-dependent measurement tools. As applications of them have played significant role to evaluate students with mental disabilities; the reliability of these measures has become increasingly important issue. For this reason, in this study, generalizability theory was used to estimate the reliability of them and the role of different sources of error in the variability of measurements in the case of measuring eating by the spoon skills. The results indicated measurement results varied depending on occasions, occasion by task and task by rater effects whereas effects of tasks and raters were negligible.

GENELLENEBİLİRLİK KURAMINA GÖRE ÖLÇÜT BAĞIMLI ÖLÇME ARAÇLARINDA GÜVENİRLİK: YEMEK YEME BECERİLERİ ÖRNEĞİNDE BİR UYGULAMA

Öz

Zihinsel engelli öğrencilere bağımsız yaşama becerileri kazandırmanın en etkili yollarından birisi uygulamalı davranış analizidir. Uygulamalı davranış analizinin temelini ölçüt bağımlı ölçme araçlarıyla yapılan doğrudan ölçümler oluşturmaktadır. Ölçüt bağımlı ölçme araçlarının uygulanması zihinsel engelli öğrencilerin değerlendirilmesinde önemli rol oynadığı için bu ölçme araçlarının güvenirlikleri gittikçe önemli bir konu olmaktadır. Bu nedenle bu araştırmada bu ölçme araçlarının güvenirliği ve çeşitli hata kaynaklarının ölçüm sonuçlarının değişkenliğinde oynadığı rol, kaşıkla yemek yeme becerilerinin ölçülmesi örneğinde genellenebilirlik kuramı aracılığıyla kestirilmeye çalışılmıştır. Araştırma sonuçları, birey, birey ve görev ortak etkisi ve görev ve puanlayıcı ortak etkisinin önemli bir değişkenlik kaynağı olduğunu buna karşılık görev ve puanlayıcı ana etkisinin önemsiz olduğunu göstermiştir
