TESTS OF MODEL FIT

Chi-Square Test of Model Fit

          Value                            656.075*
          Degrees of Freedom                    15**
          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                            626.579
          Degrees of Freedom                    10

          TLI                                0.307

RMSEA (Root Mean Square Error Of Approximation)

          Estimate                           0.238
