  1. Note. Model 1-unrestricted model: noninvariant, unconstrained model; Model 2 measurement equivalent model- equal factor loadings; Model 3-model 2 constraints plus equal factor variance and covariances; Model 4-model 3 constraints plus equal paths; Model 5-model 4 constraints plus equal factor residuals (“fully constrainted”).
  2. ΔCFI = Change in comparative fit index. A value of ΔCFI ≤ .01 indicates that the null hypothesis of invariance should not be rejected.
  3. aBollen Stine p-value reported due to multivariate non-normality.
  4. KCS that indicated “don’t know” to type of surgery and incision were excluded from the analysis.
