title: Two-year outcomes of treatment for methamphetamine use.
abstract: While evaluation research supports the general effectiveness of substance abuse treatment, there is not a comprehensive literature on treatment effectiveness for methamphetamine (MA) use. The authors consider three outcome measures--MA use, criminal activity, and employment--compared across three periods: 24-months pretreatment, during treatment, and 24-months post-treatment. Data are from an intensive natural history interview conducted two to three years after treatment for 349 randomly selected admissions to treatment for MA abuse in a large publicly-funded county treatment system. Through this naturalistic design, data provide a system-wide perspective on effectiveness of treatment as usual. Results showed reduction in MA use and crime during and following treatment and increased employment following treatment over pretreatment levels. Regression analyses showed higher levels of education and more time in treatment related to more positive post-treatment outcomes for all three measures. Lower percentage of post-treatment months with MA use also was related to more pretreatment MA-related problems, lower pretreatment MA use, and residential (compared to outpatient) treatment modality. Lower post-treatment criminal activity was also related to gender (being female), lower pretreatment criminal activity, and residential modality. Higher percentage of post-treatment months with employment also was related to gender (being male), ethnicity (not African-American), and higher pretreatment employment.
