Unidimensionality: the ratio between the first and second eigenvalue (>3), % of variance explained by the first factor (>40%). Root mean square error of approximation (RMSEA), Comparative fit index (CFI), and Tucker-Lewis index, (TLI). We determined acceptable model fit as RMSEA ≤0.1, CFI and TLI ≥0.9
