ABSTRACT
 Objective: This study aimed to develop the Rational Drug Use Scale for the Turkish public. Material and Methods: The online scale surveyed 367 individuals from the general population of Turkey who completed the scale via social networks from May 1 to June 15, 2020. The construct validity was tested via exploratory factor analysis and confirmatory factor analysis based on two different samples. The factor loading of the indicator, composite reliability and the average variance extracted have to be considered to establish convergent validity. Measurement invariance testing was conducted based on gender groups. Internal consistency reliability of the Rational Drug Use Scale has been examined with Cronbach alpha and composite reliability. Results: The confirmatory factor analysis results showed that it had been revealed that the three-factor construct of the Rational Drug Use Scale ensures a perfectly model-data fit. The convergent validity of the scale was examined through item loadings, composite reliability, and average variance extracted values. The scale's reliability was examined with Cronbach's alpha and composite reliability. Both reliability coefficients show that the Rational Drug Use Scale is reliable at a reasonable level. Conclusion: It was concluded that the Rational Drug Use Scale is a valid and reliable tool for assessing attitudes towards drug use in the Turkish population.

Keywords: Rational drug use; scale; reliability; validity
ÖZET
 Amaç: Bu çalışma, Türk kamuoyuna yönelik Akılcı İlaç Kullanım Ölçeğini geliştirmeyi amaçlamaktadır. Gereç ve Yöntemler: 1 Mayıs-15 Haziran 2020 tarihleri arasında Türkiye genelinde sosyal ağlar üzerinden 367 kişiye çevrimiçi ölçek uygulandı. Yapı geçerliliği, açımlayıcı faktör analizi ve doğrulayıcı faktör analizi ile test edildi. Yakınsak geçerliliği sağlamak için göstergenin faktör yüklemesi, bileşik güvenilirlik ve çıkarılan ortalama varyans dikkate alındı. Cinsiyet gruplarına göre ölçme değişmezliği testi yapıldı. Akılcı İlaç Kullanımı Ölçeği'nin iç tutarlılık güvenirliği Cronbach alfa ve bileşik güvenirliği ile incelendi. Bulgular: Öz yeterlik, duyarlılık ve algılanan ciddiyet olmak üzere 3 faktörden ve 17 maddeden oluşan Akılcı İlaç Kullanımı Ölçeğinin, akılcı ilaç kullanımını ölçebildiği görülmüştür. Akılcı İlaç Kullanımı Ölçeğinin açımlayıcı faktör analizi ile ortaya konan yapı geçerliliği uygulanan doğrulayıcı faktör analizi ile test edilmiştir. Buna göre Akılcı İlaç Kullanımı Ölçeğinin 3 faktörlü yapısının mükemmel bir model-veri uyumunu sağladığı ortaya çıkmıştır. Ölçeğin yakınsak geçerliliği madde yüklemeleri, bileşik güvenirlik ve ortalama varyans değerleri ile incelenmiştir. Ölçeğin güvenirliği, Cronbach alfa ve bileşik güvenirliği ile incelenmiş- tir. Her iki güvenirlik katsayısı da Akılcı İlaç Kullanımı Ölçeğinin iyi düzeyde güvenilir olduğunu göstermektedir. Sonuç: Akılcı İlaç Kullanımı Ölçeğinin Türk toplumunda akılcı ilaç kullanımına yönelik tutumları değerlendirmede geçerli ve güvenilir bir araç olduğu sonucuna varılmıştır.
