Lifetime victimization and psychological distress: cluster profiles of out of treatment drug-involved women.

K-means clustering techniques were used to identify four cluster profiles characterized by unique patterns of victimization and psychological distress and further differentiated by distinct patterns of risk and protection across multiple life domains among a sample of 149 crack-using women. Results of this study suggest that important differences exist in patterns of victimization and psychological distress among drug-involved women. Identification of this variation can be used to tailor intervention strategies to the particular needs of different subgroups within the population of crack-using women.
