The results of Knol & Berger (1991) and Parry & MacArdle (1991)
(see above web page for citations) suggest that there is not much
difference in results between the Muthen method and the simpler
method of factoring tetrachoric correlations. For additional
information (including examples using PRELIS/LISREL and SAS) on
factoring tetrachorics, see

Hope this helps.
