Abstract

Purpose: The purpose of the study was to develop both a valid and reliable scale to determine the attitudes of university students towards infertility. 

Materials and Methods: This study was conducted in two phases, Study 1 (n = 443) and Study 2 (n = 309), with university students. Item analysis, exploratory factor analysis, discriminant validity, and internal reliability were calculated in Study 1. Confirmatory factor analysis and internal reliability were calculated in Study 2. 

Results: The result of exploratory factor analysis showed that the scale has a single factor structure with 12 items and confirmatory factor analysis indicated a good fit of the model for Attitudes Toward Infertility Scale. Cronbach’s alpha coefficients were .85 and .83 for two studies.

Conclusion: The findings of this study demonstrate that the Attitudes toward Infertility Scale is a reliable and valid instrument.

İnfertiliteye Yönelik Tutum Ölçeğinin geliştirilmesi: geçerlik ve güvenirlik çalışması

Abstract

Amaç: Bu çalışmayla üniversite öğrencilerinin infertiliteye yönelik tutumlarını belirlemede güvenli ve geçerli bir ölçme aracının geliştirilmesi amaçlanmıştır.

Gereç ve Yöntem: Çalışma iki aşamada gerçekleştirilmiştir, birinci çalışmaya 443, ikinci çalışmaya 309 öğrenci katılmıştır. Çalışma 1' de ölçme aracının madde analizi ve açımlayıcı faktör analizi yapılmış, ayırtedicilik geçerliği ve iç tutarlılığa dayalı güvenirliği hesaplanmıştır. Çalışma 2' de doğrulayıcı faktör analizi yapılmış ve iç tutarlılığa dayalı güvenirliği hesaplanmıştır.

Bulgular: Açımlayıcı faktör analizi sonuçları 12 maddeden oluşan ölçeğin tek faktörlü bir yapıda olduğunu gösterirken, doğrulayıcı faktör analizi sonuçları modelin iyi uyum gösterdiğine işaret etmektedir. Cronbach alfa güvenirlik katsayısı iki çalışmada sırasıyla .83 ve .85 olarak hesaplanmıştır. 

Sonuç: Çalışma bulguları İnfertiliteye Yönelik Tutum Ölçeğinin geçerli ve güvenilir bir ölçme aracı olduğunu göstermektedir.
