Confirmatory factor analysis models of the Mizan meta-memory and meta-concentration scale for students (MMSS) in university students. A: 2-Factor, B: 2-Factor model with incorporation of modification indices (correlated error terms). BMMS: Brief Meta-memory sub-scale; BMCS: Brief Meta-concentration sub-scale, bmms_1 to bmms_5: items of BMMS, bmcs_1 to bmcs_4: items of BMCS. All coefficients are standardized. Ovals latent variables, rectangles measured variables, circles error terms, single-headed arrows between ovals and rectangles factor loadings, single-headed arrows between circles and rectangles error terms. Amos does not display standardized values of uniqueness on the models; therefore models were manually edited to put numerical values taken from the Amos text output (Estimates→Scalars→Variances)
