I'm trying to test a SEM with several reflective constructs. I want to add Political Party Affiliation and Political Orientation (e.g. democratic, republican) to the model. I have used two questions with categorical answer choices to gather data. I used Likert scale for my reflective constructs. I wonder if there's any way to test a model in AMOS that has both reflective constructs as well as political party affiliation and political orientation (which are directly measured using only one question). If not, I wonder if there's any way to work around.
