Doh!

SPSS won't even give you a structure matrix using varimax. What was I thinking?

Sounds like you specified an oblique rotation.

The pattern matrix elements are analogous to
the standardized regression coefficients from a
multiple regression. A given element of the
pattern matrix indicates the importance of that
variable to the factor with the influence of the other
variables partialled out.

The structure matrix elements are simple correlations
of the variables with the factors. They reflect all
paths from a factor to a variable (this includes factor
to factor paths, since factors are correlated), while the
pattern coefficients reflect only the direct path from a
factor to a variable.

In interpreting your factor solution, you should look
at both.

Subject: difference between pattern matrix and structure matrix in EFA

Hello,

I would like ot know if anyone could explain the difference between the
pattern matrix and the structure matrix that are both included in my EFA
SPSS output. Which should I use to interpret the results?
Can they be interpreted exactly like a factor matrix?

Thank you very much!!!
