The Mathematics Self-Efficacy-Revised (MSES-R) scale (Kranzler & Pajares, 1997) has been widely used to measure students' mathematics self-efficacy. This study aims to determine the common reliability coefficient using reliability generalization, a type of meta-analysis. The research process was organized using PRISMA guidelines. The average consistency reliability was calculated as 0.901 with a 95% CI [0.864; 0.939] using a random effect model. The studies showed heterogeneity [Q (6) = 219.788; p < .01; I2 = 96.99%]. The meta-analysis predicts that certain moderator variables significantly affect the scale's reliability. The reliability generalization analysis of the MSES-R scale reveals the different properties of the MSES-R inventory using a mixed effect model. It was found that sample type and department context significantly affect the Cronbach alpha coefficient of the MSES-R scale (p < 0.01), while the study location variable does not significantly affect the common coefficient (p > 0.01).

Matematik Öz-Yeterlik Revize Ölçeği (MSES-R), Kranzler ve Pajares (1997) tarafından geliştirilen ve öğrencilerin matematik öz-yeterlik düzeylerini ölçmek amacıyla yaygın şekilde kullanılan bir ölçme aracıdır. Bu çalışma, güvenirlik genellemesi olarak bilinen bir meta-analiz türü aracılığıyla, MSES-R ölçeğinin ortak güvenirlik katsayısını belirlemeyi amaçlamaktadır. Araştırma süreci, sistematik derleme ve meta-analiz çalışmalarına yönelik PRISMA yönergeleri doğrultusunda yapılandırılmıştır. Meta-analiz sonuçlarına göre, rastgele etkiler modeli kullanılarak hesaplanan ortalama iç tutarlılık katsayısı %95 güven aralığında [0.864; 0.939] olmak üzere 0.901’dir. Analize dahil edilen çalışmalar arasında anlamlı düzeyde heterojenlik saptanmıştır [Q(6) = 219.788; p < .01; I² = %96.99]. Ayrıca, analiz kapsamında incelenen bazı moderatör değişkenlerin ölçeğin güvenilirliğini anlamlı düzeyde etkilediği görülmüştür. Örneklem türü ve çalışmanın yapıldığı bölüm bağlamı, MSES-R ölçeğine ilişkin Cronbach alfa katsayısını anlamlı biçimde etkilemektedir (p < .01). Öte yandan, çalışma yeri değişkeninin ortak güvenirlik katsayısı üzerinde anlamlı bir etkisinin bulunmadığı belirlenmiştir (p > .01).Bu bulgular, karma etki modeliyle yürütülen güvenilirlik genelleme analizinin, MSES-R ölçeğinin bağlamsal özelliklerine duyarlılığını ortaya koyduğunu göstermektedir.
