Within my master thesis I have to work with a SEM and I did a horrible mistake. My initial plan was to follow this structure:

1. Hypothesis development

2. Modelling / Operationalization / ...

3. Pretest (one-dimensionality with exploratory factor analysis)

4. Adaptation of items / factors

5. AMOS / Confirmatory factor analysis

6. Results ...

7. ...

Here's my problem: I forgot to make a pretest (step 3) and sent out the questionnaires to all participants. The survey is already finished and I got 150 responses. However, the mess is that the items don't load on the latent variables as predicted. I predicted 5 latent variables. The items only load on three.

What should I do now? Is it possible to adapt my model according to the new insights on factor loadings?

Thx in advance!

Cheers
