  1. (1): Multivariate logistic regression analysis with dependent variable the General Health Index of GHQ-28 and independent variables the major demographic variables and the statistically significant variables of the univariate comparisons. The predictive values were calculated based on the probability of being "psychiatric case" and the cut-off value between "case" and "non-case" was 0.500. The multivariate regression analysis correctly classified 78.6% of the cases, with a Nagelkerke R Square = 0.147; (2): 95% confidence interval; (3): chi-square tests; (4): two-tailed t-test; All the VIFs for individual variables were less than 2 and all tolerances were close to 1.
