Note. CFA: N = 1025; MI: n₁ = 1025; n₂ = 1654. We did not consider the χ² test for model rejection, because its sensitivity increases with sample size: In large samples—as is the case in this study—even small model–data discrepancies produce significant results (Bollen & Long, 1993; Cheung & Rensvold, 2002)
