# does it make sense to test second order factor model in sem even some first order factors are related to each other adversely

I have try to conduct a second order factor consisting of five first order factors. However, some of the first order factors are related to each other negatively, while others are related to each other positively. I checked some of the books but I could not find the answer. When I conduct the analyses I get higher goodness of fit statistics which are above the cut points. So, does it make sense to make analyses with those factors?
