A Reliability Generalization Meta-Analysis of Mathematics Self Efficacy- Revised (MSES-R) Scale)

OpenAlex · English

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).
