- Methamphetamine Days of Abstinence : Proportion of Days Abstinent [ Time Frame: Weekly while in treatment (9 weeks) and 4 and 6 month follow up ]The proportion of days abstinent from methamphetamine was represented by univariate averages at each interview of the overall adjusted longitudinal treatment effects for each of the Standard (SMI) and Intensive (IMI) conditions. For example, a baseline average of 0.55 at baseline represents that study participants were abstinent, on average 55% of the days measured.
- Addiction Severity Index [ Time Frame: Baseline, 2-,4-, and 6-month follow up ]Addiction Severity Index - Lite (ASI) is a standardized, structured interview that assesses past 30 days problem severity in seven areas. These seven areas include medical, employment, drug, alcohol, legal, family/social and psychiatric status. Problem severity is rated on a scale of 0.0 - 1.0 with a higher score indicative of more problem severity. All scales have a range from 0 to 1.0.
