Note. CFI = confirmatory fit index; TLI = Tucker‐Lewis index; RMSEA = root mean square error approximation; SRMR = standardized root mean square residual; BIC = Bayesian information criterion; r_EXT‐INT = Pearson correlation between the latent specific internalizing and externalizing factors; r_EXT‐FRS = Pearson correlation between the latent specific externalizing and fears factors; r_EXT‐DIS = Pearson correlation between the latent specific externalizing and distress factors; Δχ² = Satorra‐Bentler difference chi‐square test; df = degrees of freedom; best‐fitting models of each type are in bold.

^aMania did not load on either distress or fears in any three‐factor model.
