  1. Note: Age is the control variable. B s were tested through the Wald χ2 statistic with d.f. = 1. a: The tests of mediating effects caused by mental health problem history. b: The tests of mediating effects caused by intimate partner violence. The test results for the male group were omitted, as the results were not significant.
