Note: CFA models were run on a second independent half of the dataset from those used in exploratory factor models. χ2 = chi-square statistic; df = degrees of freedom; CFI = comparative fit index; FO = first-order factor; RMSEA = root mean square error of approximation statistic; SO = second-order factor; TLI = Tucker-Lewis index
