TESTS OF MODEL FIT

Chi-Square Test of Model Fit

Value                            158.647*
Degrees of Freedom                     5**
P-Value                           0.0000

*  The chi-square value for MLM, MLR, MLMV, WLSM and WLSMV cannot be used for
chi-square difference tests.  MLM and MLR chi-square difference testing is
described on page 360 in the Mplus User's Guide.

** The degrees of freedom for MLMV and WLSMV are estimated according to
formula 110 (page 358) in the Mplus User's Guide.

Chi-Square Test of Model Fit for the Baseline Model

Value                            149.825
Degrees of Freedom                     2
