Modification index in EFA PreviousNext

Dear Drs. Muthen,

I was running an EFA with 5 items and only a one-factor solution was produced. Model fitness was mediocre so further modification was needed.

The modification index showed that one item had high MIs and EPCs with several other items. Does it mean that removing this item would lead to noticeable changes in other items and thus it should be the one considered for removal?

You should get both a one- and two-factor solution with five factor-indicators. I would look at the two-factor solution. A residual covariance between two items suggests a possible need for another factor.

Dear Drs. Muthen,
I performed EFA like below.
I added one modification index to improve the model fit. But it hasn't changed the fit at all, so I got just the same result without the modification index. Could you tell me what kind of a problem happened?
