Haider --
You may want to consider another
approach:
1. Use "Policy Capturing", "Judgment
Analysis (JAN)", "Policy Specifying" or any of your
favorite Multi-Attribute Decision Model approaches
to obtain ONE function of
your THREE DEPENDENT VARIABLES.
IMHO, Only human(s) should make
judgments
about how to combine multiple dependent
variables.
After that, you now have Y = function of (your
THREE DEPENDENT VARIABLES)
2. Then you use your favorite
regression
program to predict Y = function of (your
PREDICTOR VARIABLES)
This approach is not involved with factor analysis
interpretation.
However, if you want to do a factor analysis on
the PREDICTORS, then you can
USE THE FACTOR SCORES AS PREDICTORS. The
disadvantage of using factor scores
is that you still have to use ALL OF THE PREDICTOR
VARIABLES. So if you
would like to reduce the number of predictors,
then you should NOT use
factor scores but use regression
models.

Subject: Factor analysis
|
| I have conducted a factor analysis on some questionnaire items. The
| dependent variables that I am measuring for example ('Intention To Buy',
| 'Attitude towards a product' and 'Trust in buying the product from a
| merchant' ) seem to load significantly high on two factors which leaves me
| with a NOT SIMPLE FACTOR STRUCTURE.
|
| I am assuming that since 'Intention To Buy', 'Attitude towards a product'
| and 'Trust in buying the product from a merchant' all seem to be some type
| of an ATTITUDE , the significantly high factor loadings on the two factors
| may be justifiable.
|
| My questions are:
|
| 1. Are my above interpretations of the result correct?
|
| 2. If not, is there a statistical method that can help me overcome this
| 'non-simple factor structure'?
|
| Thanks.
