“…A secondary analysis of data from the prospective U.S. National Treatment Improvement Evaluation Study including 1,123 women and 2,019 men in 59 treatment facilities (Marsh et al, 2004) found that receipt of comprehensive services, including educational, housing, and income support, were related to post-treatment outcomes for both men and women. When gender differences have been found, adult women generally have had better outcomes than men, despite differences in populations targeted, type of treatment, problem drug, and treatment setting (de Leon and Jainchill, 1981;Hser et al, 2005;Fiorentine et al, 1997;Jarvis., 1992;Kosten et al, 1993;Kranzler et al, 1996;McKay et al, 2003;Nurco et al, 1988;Project MATCH, 1997;Rivers et al, 2001;Sanchez-Craig et al, 1991;Satre et al, 2004;Stephens et al, 1994;Timko et al, 2002). For example, while women had more severe family and social problems at treatment entry in a study of cocaine-dependent individuals admitted to an inpatient treatment program , there were no gender differences in family and social problems at follow-up, and women were more likely than men to have remained abstinent at six-month follow-up.…”
