Mean ± standard deviation is listed unless otherwise noted. Mean and SD represent the mean and standard deviation of the total number of childhood traumas reported by the ETI-SR. P-values represent Wilcoxon rank sum two sided normal approximation tests or chi square tests.
a
Continuous variables used is z approximation of Mann–Whitney U statistic, where z = (U − mU)/σU and discrete statistic is usual chi square (df) or Fisher’s Exact Test where applicable.
b
Caucasian group contains two pacific islanders; subjects not included in this category are African American.
c
Includes married but separated.
