  1. Question included a broad term that contact with health professionals for distress, stress, emotional disturbance, psychological problems, and nervousness. * Likelihood ratio test for each level of the multinomial outcome. § Likelihood ratio test for combining alternatives. P-value corresponds to the probability that the odds ratio of a given variable with CSA before age 12 and from ages 12 to 18 is the same, indicating that both levels of the dependent variable could be collapsed. # Probability that the association of each independent variable with each of the levels of the dependent variable (child sexual abuse) is simultaneously null according to the likelihood ratio test.
