The latent class factor model implemented in Latent Gold
from Statistical Innovations is a nice approach to this
problem.  See www.statisticalinnovations.com .

hi all,

i would like to examine the factor structure of a 20 item 'true/false' scale
i'm currently using.  the authors have indicated that this measure

has a single factor solution, however my intuition says otherwise. could you
direct me to a few literary sources that specifically addresses factor
analysis with a dichotomous variable?

thanks in advance,
~aw
