Using chi-square tests, we compared responses to the predictor variables to having experienced any maltreatment versus no maltreatment. Then, we conducted logistic regression analysis to examine the relationship between the six-category maltreatment variable (from the eight-category maltreatment variable, sexual abuse only, sexual and physical abuse, and sexual abuse and neglect were collapsed into one variable because of the small sample size) and adolescent binge drinking, controlling for age at Wave I, gender, race/ethnicity, parental alcoholism, parental education, income, and working outside the home. Parental education and income were excluded from the final model because they are not significantly associated with binge drinking at p<0.20. SUDAAN was used for all analyses that were weighted using the grand sampling weight for longitudinal analyses.
