Psychopathology influences treatment retention among drug-dependent women.

Three subgroups of drug dependent women (N = 78) were identified through cluster analysis on MCMI-II scores. Group 1 (26%) presented a relatively benign clinical picture. In contrast, Group 2 (37%) evidenced severe addiction, psychiatric (Axis I), and personality (Axis II) problems. Group 3 (37%) was characterized by fewer Axis I problems, prominent addiction and externalizing (Cluster B) personality deficits. Group membership was significantly associated with retention in a gender-specific day treatment program. Group 2 experienced rapid attrition, with only 36% completing treatment, compared to 57% for Group 1 and 76% for Group 3. Results indicate that drug-dependent women with externalizing psychopathology can be retained in treatment when environmental barriers are removed and an adequate "holding environment" is maintained. However, women with severe psychiatric problems, unstable mood, and interpersonal deficits are less likely to complete treatment. Early identification of women at risk for drop-out affords an opportunity to intervene to prevent its occurrence.
