Presentation Transcript

  1. Multitrait-Multimethod Validity • SEM permitted potential analytical methods: • Use CFA (Alwin, Joreskog, etc) see Corten et al for references • Alternate models developed: • Additive models: CU model with COV(ijI’j) =aj • Multiplicative models: CU

  2. MULTITRAIT-MULTIMETHOD MODELING: CORRELATED TRAIT-CORRELATED METHOD MODEL (CT-CM) X11 T1 M1 X12 X21 T2 M2 X22 Not estimable without restrictions

  3. MULTITRAIT-MULTIMETHOD MODELING: CORRELATED UNIQUENESS METHOD MODEL (CU) e11 X11 T1 e12 X12 e21 X21 T2 e22 X22 Not estimable without restrictions

  4. CORRELATED UNIQUENESS MODEL

  5. RECOMMENDATIONS • CTCM (Corten et al) followed by CU if CTCM does not converge • Theoretically specificed CTCM or CU
