This study explores the influence of gender on changes in recovery status among participants in a longitudinal study. The study sample (N = 1,202; 60% female) is recruited on referral to treatment, and annual interviews are conducted from Years 2 to 6 following intake. At each annual observation, participants are classified into one of four statuses (recovery, treatment, incarcerated, and using), and the transitional probabilities and correlates of transitioning from one status to another are estimated.

This article examines the effectiveness of quarterly Recovery Management Checkups (RMCs) for people with substance disorders by level of co-occurring mental disorders (34% none, 27% internalizing disorders, and 39% internalizing and externalizing) across two randomized experiments with 92% to 97% follow-up. The 865 participants are 82% African American, 53% female, and age 37 on average. RMC involves identification of those in need of treatment, motivational interviews, and treatment linkage assistance.

Background: Given today's telecommunications environment, random digit dial (RDD) telephone surveys face declining response rates and coverage, and increasing costs. As an alternative to RDD, we surveyed participants in a randomly recruited standing Internet panel supplemented with a randomly sampled telephone survey of nonpanel members for a study of associations between onset of alcohol use and later alcohol-related problems. The purpose of this paper was to compare results from our survey with results from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a face-to-face probability sample survey of 43,093 adults, with a focus on associations between demographics, age of drinking onset, and alcohol dependence.

This study examined the rates and correlates of self-reported receipt for mental health services among 1,190 adolescents, aged 12-19, who were admitted to community-based substance abuse outpatient clinics and had a co-occurring mental health problem. Utilization of mental health service was ascertained 3 months post-intake. About one third (35%) of adolescents with a co-occurring mental health problem identified at intake received mental health service in the 3 months after treatment entry.

The effectiveness of adolescent treatment to reduce substance use has been demonstrated by a number of different literature reviews, yet longer term outcome studies have suggested that continued alcohol and other drug use is common. Participation in continuing care services and reductions in environmental risk factors (e.g.

As the field follows recommendations to introduce standardized assessments on substance, mental, and behavioral problems, a consistent picture has emerged that co-occurring disorders are common, that there is heterogeneity in the type of disorder, and that the pattern varies by age. This study examines the prevalence of self-reported substance use and mental health problems, the pattern of comorbidity, and how both vary by age among people presenting to substance abuse treatment. Data are from 4,930 adolescents and 1,956 adults admitted to substance abuse treatment in multisite studies who were assessed with the Global Appraisal of Individual Needs and categorized into five age groups: <15, 15-17, 18-25, 26-39, and 40+ years.

Substance abuse treatment programs are being pressed to measure and make clinical decisions more efficiently about an increasing array of problems. This computerized adaptive testing (CAT) simulation examined the relative efficiency, precision and construct validity of different starting and stopping rules used to shorten the Global Appraisal of Individual Needs' (GAIN) Substance Problem Scale (SPS) and facilitate diagnosis based on it. Data came from 1,048 adolescents and adults referred to substance abuse treatment centers in 5 sites.

Reconciling urine results and self-reports is a classic challenge in substance abuse treatment research in general. For adolescents, the problems are compounded by the facts that they are more likely to use marijuana (which takes longer to metabolize) and to be coerced into treatment (which may increase lying). This article examines the construct and predictive validity of several different approaches for combining urine and self reported drug use including using common individual measures (urine tests and self-reported recency, frequency, and peak use), taking either as positive, using a summary scale, and using a latent model.

The Global Appraisal of Individual Needs (GAIN)1 is a 1-2 hour standardized biopsychosocial that integrates clinical and research assessment for people presenting to substance abuse treatment. The GAIN - Short Screener (GSS) is 3-5 minute screener to quickly identify those who would have a disorder based on the full 60-120 minute GAIN and triage the problem and kind of intervention they are likely to need along four dimensions (internalizing disorders, externalizing disorders, substance disorders, and crime/violence). Data were collected from 6,177 adolescents and 1,805 adults as part of 77 studies in three dozen locations around the United States that used the GAIN.

The association of early alliance to treatment attendance and longitudinal outcomes were examined in 356 adolescents participating in a randomized clinical trial targeting cannabis use. Both patient and therapist views of alliance were examined, and outcomes were evaluated over 12 months after numerous other sources of variance were controlled. Patient-rated alliance predicted a reduction in cannabis use at three and six months and a reduction in substance-related problem behaviors at six months.

Digital tomosynthesis is an imaging technique to produce a tomographic image from a series of angular digital images in a manner similar to conventional focal plane tomography. Unlike film focal plane tomography, the acquisition of the data in a C-arm geometry causes the image receptor to be positioned at various angles to the reconstruction tomogram. The digital nature of the data allows for input images to be combined into the desired plane with the flexibility of generating tomograms of many separate planes from a single set of input data.

Background: Previous studies suggest that worry content and prevalence may vary as a function of age, but evidence is limited.

Method: Cross-sectional national survey of 8580 householders in Great Britain aged between 16 and 74 years. This analysis examined the relationship between age, worry content (relationships/family, financial/housing, work, health, miscellaneous), common mental disorders, and functional limitation, adjusting for other sociodemographic factors.
