Simple structure is present when each item loads high on one factor and
low on all of the others. You have not said whether the two factors you
extracted can be named (if the first factor is ATTITUDE TOWARD PRODUCT
X, then what is the second factor?). Confirmatory factor analysis (CFA)
is a special case of SEM (specifically the measurement model part of
SEM). I would say that 50 cases is probably too low to warrant much
confidence in the results of an exploratory factor analysis or CFA.
