Examination of the standardized parameter estimates from the 2-factor model revealed a high correlation between the Distress and Fear factors (.70 for lifetime diagnoses and .69 for 12-month diagnoses) suggesting that both are subfactors of a higher order internalizing factor. Based on this and highly similar findings by Krueger (1999), we reparameterized the two-factor model by defining Distress and Fear as latent indicators of a higher-order “Internalizing” factor.
