  1. FL factor loading, IN intercept, e error variance, S.E. standard error, df degrees of freedom, ∆x2= on release of parameter; Critical Ratio (C.R.) for all items ≥ 9.0
  2. a = FL, IN and e are freely estimated for each item simultaneously; In case of RS (p ≤ .05), a second, italicized row was generated with estimated parameters (1st value: pregnancy, 2nd value: birth); b dfdiff for all model comparisons = 1
