From: Obstetric triage systems: a systematic review of measurement properties (Clinimetric)
Measurement Property | Rating a | Criteria |
---|---|---|
Structural validity | + | CTT: CFA: CFI or TLI or comparable measure > 0.95 or RMSEA< 0.06 or SRMR < 0.08b IRT/Rash: No violation of unidimensionalityc: CFI or TLI or comparable measure > 0.95 or RMSEA,0.06 or SRMR < 0.08 AND No violation of local independence residual correlations among thr items after controlling for the dominant factor < 0.20 or Q3’s < 0.37 AND No violation of monotonicity: adequate looking graphs or item scalability > 0.30 AND Adequate model fit: ITR:χ2 > 0.01 Rasch: infit and outfit mean squares ≥0.5 and ≤ 1.5 OR Z- standardized values > − 2 and < 2 |
