I'm comparing a model with only main effects with a model with both main effects and two interactions. Since mPlus doesn't give me model fit information for interaction model except AIC and BIC, I compare these two models based on AIC and BIC.
But my problem is: for AIC, the moderation model fits better; for BIC, it fits worse. However, the result of sample-size adjusted BIC is consistent with AIC, indicating the model with interactions is better. In this case, can I go by the SA BIC?
My sample size is 482 and there are significant interactions.
