I'm a beginner when it comes to CFA (in AMOS) and was wondering if anyone could advise me.
I've questionnaire data from two separate samples and I want to confirm the factor structure. I've run an EFA on the first sample (N=395, 36 items, 4 factors) and am trying to confirm that structure in the second sample (N=253). The fit indices are generally poor, despite reasonable factor loadings (>.3, majority >.6): Cmin 1280.25, df=588 CFI =.895 TLI = .888 RMSEA = .055
What are the next steps I should do to investigate the source of the poor fit. I've looked online but can't find a guide that I can follow for my level of knowledge.
