  ABSTRACT: Introduction and Aims. Although psychiatric symptoms are frequently observed in methamphetamine (MA) users, little is known about the prevalence of psychiatric disorders in MA-dependent individuals. This is the first study to examine the association of psychiatric disorders with substance use and psychosocial functioning in a large sample of MA users 3 years after treatment. We predicted that psychiatric diagnoses and severity would be associated with substance use and poorer overall functioning over the 3 year post-treatment course. Design and Methods. Participants (N = 526) received psychosocial treatment for MA dependence as part of the Methamphetamine Treatment Project and were reassessed for psychosocial functioning and substance use at a mean of 3 years after treatment initiation. DSM-IV psychiatric diagnoses were assessed at follow-up using the Mini-International Neuropsychiatric Interview. Psychosocial functioning was assessed using the Addiction Severity Index. Results. Overall, 48.1% of the sample met criteria for a current or past psychiatric disorder other than a substance use disorder. Consistent with prior reports from clinical samples of cocaine users, this rate was largely accounted for by mood disorders, anxiety disorders and antisocial personality. Those with an Axis I psychiatric disorder evidenced increased MA use and greater functional impairment over time relative to those without a psychiatric disorder. Discussion and Conclusions. This initial investigation of psychiatric diagnoses in MA users after treatment indicates elevated rates of Axis I and II disorders in this population and underscores the need for integrated psychiatric assessment and intervention in drug abuse treatment settings.[Glasner-Edwards S, Mooney LJ, Marinelli-Casey P, Hillhouse M, Ang A, Rawson RA, The Methamphetamine Treatment Project Corporate Authors.

  ABSTRACT: Aims This study examines the utility of individual drug use and treatment characteristics for predicting in-treatment performance and post-treatment outcomes over a 1-year period.Design, setting and participants Data were collected from 420 adults who participated in the Methamphetamine Treatment Project (MTP), a multi-site study of randomly assigned treatment for methamphetamine dependence. Interviews were conducted at baseline, during treatment and during three follow-up time-points: treatment discharge and at 6 and 12 months following admission.Measurements The Addiction Severity Index (ASI); the Craving, Frequency, Intensity and Duration Estimate (CFIDE); and laboratory urinalysis results were used in the current study.Findings Analyses addressed both in-treatment performance and post-treatment outcomes. The most consistent finding is that pre-treatment methamphetamine use predicts in-treatment performance and post-treatment outcomes. No one variable predicted all in-treatment performance measures; however, gender, route of administration and pre-treatment methamphetamine use were significant predictors. Similarly, post-treatment outcomes were predicted by a range of variables, although pre-treatment methamphetamine use was significantly associated with each post-treatment outcome.Conclusions These findings provide useful empirical information about treatment outcomes for methamphetamine abusers, and highlight the utility of assessing individual and in-treatment characteristics in the development of appropriate treatment plans.
