Because of the strong correlations among the three trauma measures, the CTQ-SF total score, TLEQ count of events, and TSC-40 total scores were tested sequentially rather than simultaneously as predictors of relapse in a series of logistic regression models. Based on previous findings that childhood trauma predicted relapse to cocaine use in women but not in men,13 we conducted these logistic regression analyses separately for men and women. Preliminary analyses of within-gender differences in the demographic and clinical characteristics of relapsers and abstainers were conducted using independent samples t-tests for normally distributed continuous variables, Mann-Whitney U tests for non-normally distributed continuous variables, and Fisher’s Exact Tests for categorical variables. All logistic regression models controlled for any differences observed in preliminary analyses at the p < .10 level.
