Gastro-Intestinal, ENT = Ear, Nose, Throat. Parameters are fully standardized estimates from LISREL. For Income (0 = less than or equal to 30K, 1 = more than 30K) and Gender (0 = Males, 1 = Females), the dichotomous variable is not standardized. All parameter estimates are standardized and significant at p ≤ .001. Model fit: RMSEA = .065, CFI = .96, GFI = .97. The three correlated errors shown as curved arrows were 0.09, 0.10, 0.11.
