Measurement error of scores on the Mathematics Anxiety Rating Scale across studies Academic Article uri icon


  • The Mathematics Anxiety Rating Scale (MARS) was submitted to a reliability generalization analysis (RG) to characterize the variability of measurement error in MARS scores across administrations and identify possible study characteristics that are predictive of score reliability variations. In general, the MARS and its variants yielded scores with strong internal consistency and test-retest reliability estimates, although variation was observed. Adult samples were related to lower score reliability compared to other age groupings. Inclusion of total score standard deviation in the regression models resulted in roughly 25% increases in R2 effects.
