Table 4. Multiple-Group CFA (Model 2b) for 26 DEMQOL-Proxy Items (Unstandardised Factor Loadings With Bootstrapped Standard Errors): Scalar Invariance Estimates.
| Item | DEMQOL (n = 1404), DEMQOL-Proxy EL (n = 909), DEMQOL-Proxy ES (n = 495) | h2 | GEN | SE | NEG | SE | APP | SE | FIN | SE | COG | SE |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Note. GEN = general HRQL; NEG = negative emotion; APP = worries about physical appearance; FIN = worries about finance-related tasks; COG = worries about cognition. Model fit from non-bootstrapped results: χ2 = 2,254.917 (df = 648), English (EL) χ2 = 934.728, Spanish (ES) χ2 = 1,320.188. Root mean square error of approximation (RMSEA) = .059 (90% confidence interval [CI] = .057, .062), comparative fit index (CFI) = .943. DIFFTEST χ2 = 405.844 (Δdf = 86), p < .0001. h2 = communalities. | ||||||||||||
