No missing data, all cases were observed on all variables. Latent class indicators are bolded. Each class indicator was scored as 1 = not endorsing the item and 2 = endorsing the item. Maltreated participants were coded as 1, non-maltreated as 0. Type = whether the presented statistic for that variable is a mean or a frequency count. Odds ratios were conducted to detect differences in binary or dichotomous variables; whereas t-tests were conducted to detect differences in continuous variables.
Number of romantic partners ranged from 0-8.
Number of penetrative sex partners ranged from 0-5 and included participants who were not sexually active.
Age at first voluntary penetrative sex means are based upon the scale described in the text, not chronological age.
