Özet:

 In this study, it was aimed to conduct a validity and reliability study of the Mullen Early Learning Scale developed by Mullen 1995 to determine the developmental levels of 0-68 month-old infants and children for 13-44 month-old infants and children. The study group consisted of 365 infantschildren aged 13-44 months who did not have any developmental delay diagnosis came to Family Health Centers in Sivas city center. In the adaptation study of Mullen Early Learning Scale, language and content validity studies were carried out. Principal component analysis, estimations of item parameters and parameter invariance were examined for construct validity. As a result of the eigenvalue and explained variance ratios obtained as a result of principal components analysis, it was revealed that the sub-dimensions were unidimensional and therefore locally independent. With the estimation of item parameters, the easiest and most difficult items were determined for the sub-dimensions of the scale. Parameter invariance was ensured because the parameter invariance was above 70 of the correlation coefficients. According to the Classical Test Theory for reliability, Cronbachs Alpha coefficient and test-retest reliability coefficient were calculated according to the Item Response Theory, and the marginal reliability and empirical reliability coefficients were calculated. Cronbachs Alpha coefficients of the sub-dimensions of the scale were 0.93; test-retest coefficients 0.96; marginal reliability coefficients 0.66; empirical reliability coefficients were found to be 0.94 and test-retest reliability coefficients were found to be 0.96. The findings show that the Mullen Early Learning Scale can be used as a valid and reliable measurement tool for infantschildren aged 13-44 months.

 Çalışmada, 0-68 aylık bebek ve çocukların gelişim düzeylerini belirlemeye yönelik Mullen 1995 tarafından geliştirilen Mullen Erken Öğrenme Ölçeğinin 13-44 aylık bebek ve çocuklar için geçerlik ve güvenirlik çalışmasının yapılması amaçlanmıştır. Çalışma grubunu, Sivas il merkezinde Aile Sağlığı Merkezlerine gelen herhangi bir gelişimsel gecikme tanısı bulunmayan 13-44 ay arası 365 bebekçocuk oluşturmuştur. Mullen Erken Öğrenme Ölçeğinin uyarlama çalışmasında; dil ve kapsam geçerliği çalışmaları yapılmıştır. Yapı geçerliği için temel bileşenler analizi, madde parametrelerinin kestirimleri ve parametre değişmezliğine bakılmıştır. Temel bileşenler analizi sonucu elde edilen özdeğer ve açıklanan varyans oranlarının sonucunda alt boyutların tek boyutlu olduğu ve dolayısıyla yerel bağımsız olduğu ortaya konulmuştur. Madde parametrelerinin kestirimi ile ölçeğin alt boyutları için en kolay ve en zor maddeleri belirlenmiştir. Parametre değişmezliği korelasyon katsayılarının  70 üzerinde olduğu için parametre değişmezliği sağlanmıştır. Güvenirlik için Klasik Test Kuramına göre ise Cronbachs Alpha katsayısı ve test tekrar test güvenirliği katsayısı Madde Tepki Kuramına göre marjinal güvenirlik ve ampirik güvenirlik katsayısı hesaplanmıştır. Ölçeğin alt boyutlarının Cronbachs Alpha katsayıları 0,93; test tekrar test katsayıları 0,96; marjinal güvenirlik katsayılarının 0,66; ampirik güvenirlik katsayıları 0,94 ve test tekrar test güvenirlik katsayısı 0,96 bulunmuştur. Bulgular Mullen Erken Öğrenme Ölçeğinin 13-44 aylık bebeklerçocuklar için geçerli ve güvenilir bir ölçme aracı olarak kullanılabileceğini göstermektedir.
