Survival analysis of three treatment modalities in a residential substance abuse program for women and children.

Retaining women in substance abuse treatment is difficult. Increased length of stay (LOS) has been found to be predictive of positive treatment outcomes, including lower drug use, criminal behavior, and unemployment among adults, and improved growth and development for children. This study used survival analysis statistical methods to examine LOS in a residential treatment program for women and children as the program shifted from a traditional therapeutic community, to gender-specific programming, to interdisciplinary, family-focused treatment. Results suggest that with implementation of family-focused treatment, LOS increases more than with gender-specific programming alone.
