Is there a way to determine if the indirect and direct pathways are statistically significantly different? In models with a dichotomous outcome?

Yes. You can label the direct effect in the MODEL command and use MODEL CONSTRAINT to create the indirect effect. MODEL TEST can be used to test if the two parameters are significantly different from each other.

Great could you give me some sample code to do this? Thanks and hurrah. As always you all are amazing.

See Example 5.20 where MODEL CONSTRAINT is illustrated. An indirect effect is the product of the regression coefficients that are part of the indirect effect.

See the user's guide for MODEL TEST.
