The effectiveness of the Minnesota Model for treating adolescent drug abusers
ABSTRACT The treatment outcome of drug-abusing adolescents treated with a 12-Step approach.
The study compares drug use outcome data at 6 and 12 months post-treatment among three groups of adolescents: those who completed treatment, those who did not and those on a waiting list. Also, among treatment completers, residential and outpatient samples were compared on outcome.
The treatment site is located in the Minneapolis/St Paul area of Minnesota.
Two hundred and forty-five drug clinic-referred adolescents (12-18 years old), all of whom met at least one DSM-III-R substance dependence disorder. One hundred and seventy-nine subjects received either complete or incomplete 12-Step, Minnesota Model treatment and 66 were waiting list subjects.
In addition to demographics and clinical background variables, measures included treatment involvement, treatment setting and drug use frequency at intake and follow-up.
Absolute and relative outcome analyses indicated that completing treatment was associated with far superior outcome compared to those who did not complete treatment or receive any at all. The percentage of treatment completers who reported either abstinence or a minor lapse for the 12 months following treatment was 53%, compared to 15 and 28% for the incompleter and waiting list groups, respectively.
Favorable treatment outcome for drug abuse was about two to three times more likely if treatment was completed. Also, there were no outcome differences between residential and outpatient groups. Alcohol was the most common drug used during the follow-up period, despite cannabis being the preferred drug at intake.

- "Research to-date on AOD outcomes for adolescents suggests that participation in 12-step groups is associated with improved outcomes, similar to adults (Kelly and Meyers, 2007; Sussman, 2010; Winters et al., 2000). Kelly and Myers reviewed eight empirical studies on adolescent participation in 12-step programs (Kelly and Meyers, 2007) and found that greater 12-step participation was related to abstinence. "
ABSTRACT: Adolescents who attend 12-step groups following alcohol and other drug (AOD) treatment are more likely to remain abstinent and to avoid relapse post-treatment. We examined whether 12-step attendance is also associated with a corresponding reduction in health care use and costs. We used difference-in-difference analysis to compare changes in seven-year follow-up health care use and costs by changes in 12-step participation. Four Kaiser Permanente Northern California AOD treatment programs enrolled 403 adolescents, 13-18-years old, into a longitudinal cohort study upon AOD treatment entry. Participants self-reported 12-step meeting attendance at six-month, one-year, three-year, and five-year follow-up. Outcomes included counts of hospital inpatient days, emergency room (ER) visits, primary care visits, psychiatric visits, AOD treatment costs and total medical care costs. Each additional 12-step meeting attended was associated with an incremental medical cost reduction of 4.7% during seven-year follow-up. The medical cost offset was largely due to reductions in hospital inpatient days, psychiatric visits, and AOD treatment costs. We estimate total medical use cost savings at $145 per year (in 2010 U.S. dollars) per additional 12-step meeting attended. The findings suggest that 12-step participation conveys medical cost offsets for youth who undergo AOD treatment. Reduced costs may be related to improved AOD outcomes due to 12-step participation, improved general health due to changes in social network following 12-step participation, or better compliance to both AOD treatment and 12-step meetings.Drug and alcohol dependence 05/2012; 126(1-2):124-30.

- "There are several features of adolescence that are thought to increase susceptibility to abuse drugs, such as heightened stress reactivity (Chung and Maisto 2006; Lopez et al. 2005; Rao et al. 1999; Spear 2009), increased proclivity to seek natural rewards (Casey et al. 2008; Spencer et al. 2007), and poor inhibitory control (Casey et al. 2008; Spencer et al. 2007). These factors may converge to enhance drug abuse vulnerability and may explain why adolescents, compared to adults, are more likely to initiate and maintain drug use, are more likely to binge and relapse (Winters and Lee 2008), and are more resistant to treatment (Dennis et al. 2004; Perepletchikova et al. 2008; Winters et al. 2000). Sex differences also exist in drug abuse. "
ABSTRACT: Research suggests that age and sex are vulnerability factors for drug abuse. However, few studies have systematically examined their interaction. The purpose of the present study was to examine male and female, adult and adolescent rats under a procedure that measures responding during periods of signaled availability and nonavailability of iv cocaine and food reinforcers. Adolescent and adult rats lever pressed for iv infusions of cocaine or food pellets under a procedure with three components of signaled availability of the reinforcer alternating with two components of signaled nonavailability. Adolescent rats were removed and then later retested under the same conditions as adults, and a group of adult rats was also removed and retested after a similar number of days. A subset of rats earning cocaine infusions under the initial test was later retested with food pellets under the same behavioral task to assess the influence of prior cocaine exposure on subsequent responding for a nondrug reinforcer. Adolescents (vs. adults) made more responses during periods of signaled iv cocaine availability and nonavailabiltiy, and adult females responded more than adult males during these periods. Responding during periods of signaled nonavailability of iv cocaine and food did not differ between the initial and subsequent retest conditions in adult rats. Further, adult males and females exposed to cocaine during adolescence responded more during periods of food availability compared to cocaine-naïve adults. These results indicate that sex and age are vulnerability factors in cocaine abuse, and cocaine exposure during critical developmental stages can have long-lasting effects.Psychopharmacology 02/2011; 215(4):785-99.

ABSTRACT: The investigation of the applicability of Alcoholics Anonymous/Narcotics Anonymous (AA/NA) for teens has only been a subject of empirical research investigation since the early 1990s. In the present review, the author describes teen involvement in AA/NA programming, provides an exhaustive review of the outcomes of 19 studies that used an AA/NA model as part of their formal teen substance abuse treatment programs, and provides data on the effects of AA/NA attendance on abstinence at follow-up, on which youth tend to become involved in AA/NA, and on mediation of the benefits of AA/NA participation. In addition, the author suggests the reasons for somewhat limited participation by teens in more informal, community-based 12-step meetings, and makes suggestions for maximizing participation at meetings in the community. The author concludes that AA/ NA participation is a valuable modality of substance abuse treatment for teens and that much can be done to increase teen participation, though more research is needed.Evaluation & the Health Professions 03/2010; 33(1):26-55.
