The Network for the Improvement of Addiction Treatment (NIATx) is a program funded by the Robert Wood Johnson Foundation and the Center for Substance Abuse Treatment to help substance abuse treatment facilities improve the effectiveness and efficiency of care offered to clients. A total of 38 facilities from across the country were awarded funding to implement the NIATx program between the years of 2003 to 2007. Data were extracted from administrative records from 82,274 clients. The data file covers the dates of contact and treatment with the facility, the number of follow-up units of care received, the primary substance of abuse, and basic demographic information.

The AIDS Drug Assistance Program (ADAP) Data Report (ADR) includes two components: the Grantee Report and the Client Report. All ADAPs are required to submit both reports.

The Grantee Report is a collection of basic information about the grantee characteristics and policies. It includes a Programmatic Summary section and an Annual Submission section.

The Client Report (or client-level data) is a collection of one record for each client enrolled in the ADAP. Each record includes the client's encrypted unique identifier, basic demographic data, and enrollment and certification information. A client's record may also include data about the ADAP-funded insurance and medication received, including the costs of these services, as well as HIV clinical information.

The Pathways to Desistance study was a multi-site study that followed 1,354 serious juvenile offenders from adolescence to young adulthood in two locales between the years 2000 and 2010. Enrolled into the study were adjudicated youths from the juvenile and adult court systems in Maricopa County (Phoenix), Arizona (N=654), and Philadelphia County, Pennsylvania (N=700).

The official arrests records of all 1,354 youth were obtained from multiple sources. For arrest/petitions under the age of 18, this information is based on petitions appearing in the juvenile and adult court records in each site. In Philadelphia, this information was gathered based on a hand review of juvenile and adult court documents; in Phoenix, the information is based on reports from two computerized court tracking systems (JOLTS--Juvenile On-Line Tracking System for juvenile court information, ICIS--Maricopa County Superior Court database for adult court information). For arrests/petitions over 18, FBI arrest records are the source of information. There is no self-reported information contained in this set of data.

Information from these different data sources is consolidated into the following categories:

1. Information regarding petitions with a date that falls prior to the baseline interview date ("prior petitions").
2. Information regarding the study index petition (also called the "initial referring petition"; this is the adjudication that prompted study enrollment). Information regarding the study index petition can be found by accessing the "type" variable associated with the prior petitions (specific variable name: Official Record Prior PetitionXX: Petition type). Depending on the investigator's needs, this petition can remain combined with the "priors" or be used as a stand-alone petition.
3. Information regarding arrests and court petitions with a date which falls after the baseline interview date in the Pathways study ("rearrests").

The Treatment Episode Data Set -- Discharges (TEDS-D) is a national census data system of annual discharges from substance abuse treatment facilities. TEDS-D provides annual data on the number and characteristics of persons discharged from public and private substance abuse treatment programs that receive public funding. Data collected both at admission and at discharge is included. The unit of analysis is a treatment discharge. TEDS-D consists of data reported to state substance abuse agencies by the treatment programs, which in turn report it to SAMHSA.

A sister data system, called the Treatment Episode Data Set -- Admissions (TEDS-A), collects data on admissions to substance abuse treatment facilities. The first year of TEDS-A data is 1992, while the first year of TEDS-D is 2006.

TEDS-D variables that are required to be reported are called the "Minimum Data Set (MDS)", while those that are optional are called the "Supplemental Data Set (SuDS)".

Variables unique to TEDS-D, and not part of TEDS-A, are the length of stay, reason for leaving treatment, and service setting at time of discharge. TEDS-D also provides many of the same variables that exist in TEDS-A. This includes information on service setting, number of prior treatments, primary source of referral, gender, race, ethnicity, education, employment status, substance(s) abused, route of administration, frequency of use, age at first use, and whether methadone was prescribed in treatment. Supplemental variables include: diagnosis codes, presence of psychiatric problems, living arrangements, source of income, health insurance, expected source of payment, pregnancy and veteran status, marital status, detailed not in labor force codes, detailed criminal justice referral codes, days waiting to enter treatment, and the number of arrests in the 30 days prior to admissions (starting in 2008).

Substances abused include alcohol, cocaine and crack, marijuana and hashish, heroin, nonprescription methadone, other opiates and synthetics, PCP, other hallucinogens, methamphetamine, other amphetamines, other stimulants, benzodiazepines, other non-benzodiazepine tranquilizers, barbiturates, other non-barbiturate sedatives or hypnotics, inhalants, over-the-counter medications, and other substances.

Created variables include total number of substances reported, intravenous drug use (IDU), and flags for any mention of specific substances.

MOUD remains an underutilized evidence-based practice with potential to reduce opioid use disorder (OUD) and save lives. Washington State expanded its Hub & Spoke (H&S) model for OUD medication treatment (MOUD: buprenorphine, methadone, naltrexone) by funding additional networks and developing a low-barrier, Opioid Treatment Network (OTN) model. The Washington H&S model was designed as a flexible approach incorporating primary care and substance use treatment programs, referral organizations, nurse care managers and care navigators. The OTN model offers MOUD induction in non-traditional settings (e.g., emergency departments, jails) with connections to community partners who will offer MOUD maintenance.

This study examined the implementation and effectiveness of the H&S and OTN models for increasing MOUD treatment and improving outcomes for people with OUD. Washington's H&S and OTN interventions were funded through federal STR/SOR opioid response grants, and the expanded H&S networks were funded through the state. The study, Hub and Spoke Opioid Treatment Networks: 2nd Generation Approaches to Improve Medication Treatment for Opioid Use Disorders (R01DA0561067), and its supplement (R01DA0561067S1) was part of NIH's HEAL initiative, and built on an earlier study (R33DA045851). All three studies were supported by the National Institute on Drug Abuse.

Expanding Access to Low-Barrier Opioid Use Disorder Treatment in Non-Traditional Settings: Washington's Opioid Treatment Network

• Increasing utilization of medications that treat opioid use disorders (MOUD) remains an essential strategy to curb the opioid crisis nationwide, especially among rural areas where access can present challenges. Washington State expanded access to MOUD through its opioid treatment networks (OTN), which provide low-barrier access to MOUD in non-traditional settings with an emphasis on buprenorphine and rural locations. The study examined changes in buprenorphine utilization between Medicaid beneficiaries who initiated treatment at OTNs compared to individuals outside OTN facilities and by rural-urban residence.

Differential Changes in Use of Medications for Opioid Use Disorder by Race-Ethnicity: Effects of a Hub-and-Spoke Model

• This study assessed whether delivery of opioid use disorder (OUD) treatment through a hub and spoke (HS) model is associated with better adherence to psychotropic medication treatment, compared to usual treatment. Washington State's HS model required each network to include at least one mental health program, so it was hypothesized that it would improve psychotropic medication adherence for people with both a mental health disorder (MHD) and an OUD.

Treatment for Comorbid Mental Health Disorders Among Patients Treated for Opioid Disorder: The Role of a Hub and Spoke Intervention

• The research team examined, separately for different racial-ethnic groups, whether use of medications for opioid use disorder (MOUD) increased more among people treated in a hub-and-spoke care model than among people treated in a non-hub-and-spoke model.

In 1995-1996, the MacArthur Midlife Research Network carried out a national survey of over 7,000 Americans aged 25 to 74 (ICPSR 2760). The purpose of the study was to investigate the role of behavioral, psychological, and social factors in understanding age-related differences in physical and mental health.

With support from the National Institute on Aging, an initial follow-up of the original Midlife Development in the United States (MIDUS) samples was conducted in 2004 (MIDUS 2). The daily stress and cognitive functioning projects were repeated at MIDUS 2; in addition the protocol was expanded to include biomarkers and neuroscience. In 2005, a baseline sample of 592 African Americans from Milwaukee was added to MIDUS to examine health issues in minority populations.

In 2013, a third wave (MIDUS 3) of survey data was collected on longitudinal participants. Data collection for this follow-up wave largely repeated baseline assessments (e.g., phone interview and extensive self-administered questionnaire), with additional questions in selected areas (e.g., economic recession experiences, optimism and coping, stressful life events, and caregiving). A third wave of cognitive functioning data and a second wave of the Milwaukee sample were also collected. Data collection for the daily diary, biomarkers, and neuroscience is ongoing. This dataset includes all known MIDUS decedents (N=2,533) from the Core National and Milwaukee samples as of December 2023.

The Criminal Justice Drug Abuse Treatment Studies 2 (CJ-DATS 2) was launched in 2008 with a focus on conducting implementation research in criminal justice settings. NIDA's ultimate goal for CJ-DATS 2 was to identify implementation strategies that maximize the likelihood of sustained delivery of evidence-based practices to improve offender drug abuse and HIV outcomes, and to decrease their risk of incarceration.

The Medication-Assisted Therapy (MAT) study focuses on implementing linkages to medication assisted treatment in correctional settings. During the study period community corrections staff engaged in training about addiction pharmacotherapies, while leadership in the corrections and treatment facilities engage in a joint strategic planning process to identify and resolve barriers to efficient flow of clients across the two systems.

This study includes 28 datasets and over 1,400 variables. The first five datasets for this study contain data on the baseline characteristics of the treatment and corrections sites that participated in the study as well as the characteristics of the staff working at those facilities. Opinions about Medication Assisted Treatment surveys were administered to personnel at the participating corrections and treatment sites (D6). Data on Inter-organization Relations between Probation and Parole staff with Treatment Providers were also collected (DS7-DS18).

Information was extracted from the charts of clients about their alcohol and opioid dependence as well as the referrals and treatment the clients received (DS19). Probation and parole officers and treatment providers were surveyed about monthly counts of referrals (DS20-DS21).

During the study 10 staff members from the community corrections agency and local treatment providers where MAT services were available were nominated to participate in a Pharmacotherapy Exchange Council (PEC). PEC members were involved with strategic planning for implementing changes to improve the usage of Medication-Assisted Therapy. PEC members were surveyed several times throughout the study.

PEC members completed surveys on how well the sites were adhering to the Organizational Linkages Intervention (OLI) process (DS22). Community corrections staff, PEC members and Connections Coordinators in the experimental group were surveyed about their perceptions of organizational benefits and costs associated with the MATICCE intervention (DS23). The PEC rated the Connections Coordinators (DS24)and the Connections Coordinators rate the PEC (DS25). PEC researchers completed surveys on how much of the OLI was completed (DS26) as well as what the sustainability of the changes made through the MATTICE project (DS27). The final dataset provides a key for who took the KPI (Key Performance Indicators) training and who was a PEC member (DS28).

The Army Study to Assess Risk and Resilience in Servicemembers (STARRS) is an extensive study of mental health risk and resilience among military personnel. Army STARRS consists of eight separate but integrated epidemiologic and neurobiologic studies. Survey data for three of the Army STARRS study components are available via Secure Dissemination or via the ICPSR Virtual Data Enclave: New Soldier Study (NSS); All Army Study (AAS) and Pre-Post Deployment Study (PPDS). Also available are data for the STARRS-Longitudinal Study (STARRS-LS), which are follow-up surveys conducted with Army STARRS participants from AAS, NSS and PPDS studies. Lastly, baseline administrative data from the Army/Department of Defense (DoD) and blood sample flags for Soldiers who had blood drawn as a part of their participation in NSS or PPDS are available.

The AAS component of Army STARRS assesses soldiers' psychological and physical health, events encountered during training, combat, and non-combat operations, and life and work experiences across all phases of Army service. The AAS data includes data on soldiers' psychological resilience, mental health, and risk for self-harm.

The NSS data are drawn from new soldiers who have just entered the Army. The data contain information on soldier health, personal characteristics, and prior experiences. Results from a series of neurocognitive tests are also included in the NSS data.

The PPDS data are drawn from active duty soldiers who were interviewed at four points in time: 3-4 months prior to deployment to Afghanistan; within 1-2 weeks after return from deployment; 1-3 months after return from deployment; and 9-12 months after return from deployment. The PPDS data contain information on soldiers' psychological resilience, mental health, deployment experiences, and risk for self-harm.

The STARRS-LS data are from multiple follow-up interviews with individuals who previously participated in the AAS, NSS and PPDS study components of Army STARRS. STARRS-LS data contain follow-up information on soldiers' and veterans' physical and mental health, resilience and risk for self-harm, military and employment status, deployment experience, and personal characteristics as they move through their Army careers and after they leave the Army.

The Survey of Youth in Residential Placement (SYRP) is the only national survey that gathers data directly from youth in the juvenile justice system. The Office of Juvenile Justice and Delinquency Prevention (OJJDP) designed the survey in 2000 and 2001 to survey offender youth between the ages of 10 and 20. SYRP asks the youth about their backgrounds, offense histories and problems; the facility environment; experiences in the facility; experiences with alcohol and drugs; experiences of victimization in placement; medical needs and services received; and their expectations for the future. SYRP research provides answers to a number of questions about the characteristics and experiences of youth in custody including:

• Who are the youth in placement?
• What are their offenses?
• What are their family backgrounds?
• What are their expectations for the future?
• How are youth grouped in living units and programs?
• What activities are available in each facility?
• How accessible are social, emotional, and legal supports?
• What is the quality of the youth-staff relationships?
• How clear are the facility's rules?
• How clear is the facility's commitment to justice and due process?
• What methods of control and discipline do staff use?

SYRP's findings are based on anonymous interviews with a nationally representative sample of youth in custody during the spring of 2003 using audio computer-assisted self-interview (ACASI) technology. SYRP is the latest addition to two ongoing data collections that OJJDP designed and implemented in the 1990s. It joins the Census of Juveniles in Residential Placement and the Juvenile Residential Facility Census to provide updated statistics on youth in custody in the juvenile justice system.

SYRP bulletins, reports, and a simplified online analysis tool are available from the SYRP Project Web site.

Three dashboards describe nonfatal drug overdoses within the United States:

1. DOSE Dashboard: Nonfatal Overdose Syndromic Surveillance Data
2. DOSE Dashboard: Nonfatal Overdose Emergency Department and Inpatient Hospitalization Discharge Data
3. The Fentalog Study: A Subset of Nonfatal Suspected Opioid Overdoses with Toxicology Testing

This study contains data from the first follow-up interview of the Northwestern Juvenile Project (NJP), a longitudinal assessment of alcohol, drug, or mental service treatment needs of juvenile detainees. This initial follow-up occurred approximately three years after the baseline interview and focused on studying the development and persistence of psychiatric disorders, related predictive variables, patterns of drug use, and other risk behaviors.

The project's aims included studying (1) development and persistence of alcohol, drug, and mental disorders and (2) pathways and patterns of risky behaviors. Changes in disorders over time were studied (including onset, remission, and recurrence), comorbidity, associated functional impairments, and the risk and protective factors related to these disorders and impairments. This study addressed patterns and sequences of the development of drug use and related variables, focusing on gender differences, racial/ethnic differences, the antecedents of these risky behaviors (risk and protective factors), and how these behaviors were interrelated.

The original sample included 1829 randomly selected youth, 1172 males and 657 females, then 10 to 18 years old, enrolled in the study as they entered the Cook County Juvenile Temporary Detention Center from 1995 to 1998. Among the sample were 1005 African Americans, 524 Hispanics, 296 non-Hispanic white respondents. Participants were tracked from the time they left detention. Re-interviews were conducted regardless of where respondents were living when their follow-up interview was due: in the community, correctional settings, or by telephone if they lived farther than two hours from Chicago.

The Criminal Justice Drug Abuse Treatment Studies 2 (CJ-DATS 2) was launched in 2008 with a focus on conducting implementation research in criminal justice settings. NIDA's ultimate goal for CJ-DATS 2 was to identify implementation strategies that maximize the likelihood of sustained delivery of evidence-based practices to improve offender drug abuse and HIV outcomes, and to decrease their risk of incarceration.

The Organizational Process Improvement Intervention (OPII) study (aka Assessment study) focused on implementing assessment and treatment planning processes. Screening and assessment were used to identify substance abuse-related problems and to develop programming to address the problems so identified.

The OPII study engaged corrections and treatment agencies to improve the quality of interagency communication through the effective use of assessment and case planning processes and treatment referrals. Both inter-agency and intra-agency change processes were targeted. A multi-phase implementation protocol was used, wherein agencies engaged in team development, needs assessment, planning, implementation, and sustainability in distinct steps. Early- and delayed-start sites allowed the research team to control for effects of environmental changes within states. The protocol targeted critical communications channels between otherwise often highly segregated correctional and treatment agencies.

Evaluation of the OPII used a multi-site cluster randomized design with multiple measures over the course of the intervention. Clusters consisted of a criminal justice agency and one or more community treatment providers that received referrals from that criminal justice agency. Each of the 9 centers had two clusters (one had three), and each cluster was randomized to an Early-Start or a Delayed-Start condition with multiple measures over the course of the intervention. After randomization, the Early-Start sites began the OPII, while the Delayed-Start sites conducted business as usual, without any additional intervention. After approximately 12 months, or when the Early-Start change team completed the Implementation phase, the Delayed-Start change team began to carry out the protocol.

Throughout the study period different subsets of individuals working at correctional facilities and treatment programs at the study sites were asked to complete surveys. During the Baseline period of the study survey data were collected from correctional staff, correctional directors, treatment staff, treatment directors, correctional executives and treatment executives. These data can be found in (DS1-DS12). The executive respondents provided information at the organizational level for the programs they oversaw (DS5, DS6). Next, Needs Assessments were completed by the change teams and their facilitators (DS13-DS14). The change teams and facilitators also responded to surveys on Process Improvement Planning (DS15-DS19). During the Implementation stage, surveys were administered to select substance abuse treatment programs, change team facilitators, change team members and the immediate supervisors of the change team members (DS20-DS27). Selected correctional and treatment staff members (in the Early-Start sites only) were asked to complete Follow-up surveys at the end of the OPII process (DS28-DS33). Staff members who completed surveys also provided demographic data (DS36-DS41). DS42 is a restricted use version of DS41. Change team members kept track of the time they spent on OPII activities (DS35). Change team success was evaluated by a subset of raters (DS34).

Surveys were administered at 21 study sites and there was a total of over 2,700 survey respondents.

This study contains data from the second follow-up interview of the Northwestern Juvenile Project (NJP), a longitudinal assessment of alcohol, drug, or mental service treatment needs of juvenile detainees. This second follow-up occurred approximately 3.5 years after the baseline interview and focused on the development and persistence of psychiatric disorders, related predictive variables, patterns of drug use, and other risky behaviors.

The project's aims included studying (1) development and persistence of alcohol, drug, and mental disorders and (2) pathways and patterns of risky behaviors. Researchers studied changes in disorders over time (including onset, remission, and recurrence), comorbidity, associated functional impairments, and the risk and protective factors related to these disorders and impairments. The NJP addressed the patterns and sequences of the development of drug use and related variables, focusing on gender differences, racial/ethnic differences, the antecedents of these risky behaviors (risk and protective factors), and how these behaviors are interrelated.

The original sample included 1829 randomly selected youth, 1172 males and 657 females, then 10 to 18 years old, enrolled in the study as they entered the Cook County Juvenile Temporary Detention Center from 1995 to 1998. Among the sample were 1,005 African Americans, 524 Hispanics, 296 non-Hispanic white respondents. A random subsample of 997 of the baseline participants were chosen for second follow-up interviews. Researchers tracked participants from the time they left detention and re-interviewed them regardless of where they were living when their follow-up interview was due: in the community, correctional settings, or by telephone if they lived farther than two hours from Chicago.

The study was funded by OJJDP, several institutes at the National Institutes of Health, and other federal agencies and private foundations. The National Institutes of Health funded an additional component on HIV/AIDS risk behaviors.

This study contains data from the third follow-up interview of the Northwestern Juvenile Project (NJP), a longitudinal assessment of alcohol, drug, or mental service treatment needs of juvenile detainees. The third follow-up occurred approximately four years after the baseline interview and focused on studying the development and persistence of psychiatric disorders, related predictive variables, patterns of drug use, and other risk behaviors.

Since 1976, MTF has enrolled ~2,450 individuals each year from its nationally representative annual sample of 12th graders into the MTF Longitudinal Panel study. A primary goal of MTF study is to examine potential consequences of substance use across the life course, including mortality. Therefore, the MTF Longitudinal Panel study now includes measures of mortality linked to the National Death Index (NDI).

The "MTF Longitudinal Panel Mortality Data and Weights, Cohorts 1976-2019 (Updated March 2026)" file includes MTF Longitudinal Panel members from the high school cohorts of 1976-2019 whose mortality status was confirmed through either (a) the MTF NDI match process or (b) the MTF panel tracking process (tracking through March 2026).

This updated file includes:

• The Panel Eligibility and Sampling Weight (PESW) variable to be used when mortality status is the outcome.
• Continued data management to update respondents and mortality status.

Information about the MTF project can be accessed through the Monitoring the Future website. Annual reports are published by the research team, describing the data collection and trends over time.

The Helping Young Smokers Quit (HYSQ) initiative was a multi-phase project that addressed the critical need to disseminate effective, developmentally appropriate cessation programs for young smokers. Phase I identified and described tobacco treatment programs available for youth in the United States, Phase II evaluated smoking secession programs tailored for youth to help understand what works, and Phase III identified factors associated with program sustainability. Phase II collected data from five sources: (1) program participants, (2) program providers, (3) program curricula, (4) organizational leaders, and (5) community leaders and community ordinances.

Program participants were interviewed at baseline, end-of program, 6-month follow-up, and 12-month follow-up. Topics covered by the interviews include age, gender, race, Hispanic origin, language spoken at home, employment, income, religiosity, school enrollment, education level, school grades, height, weight, extracurricular activities, recreation, sports, exercise, aspirations after high school, psychological well-being, alcohol consumption, cigarette use and use of other tobacco products, attitudes about smoking, plans to stop/continue smoking, attempts to quit smoking, reasons for participating in the program, topics/issues covered by the program, opinions about the program, and smoking experience since the beginning of the program. In addition, for each follow-up survey, the participants provided a breath sample for carbon monoxide analysis to validate self-reported quit status.

After the last session of each program delivery, the program providers, such as program leaders and cessation counselors, were interviewed about the content and delivery of the program and the reactions of the participants and themselves to the program as delivered. The program providers also kept attendance records.

Curriculum content was abstracted from program manuals and other materials used in each program.

Organizational leaders of the organizations that offered the programs were surveyed about various aspects of each organization, including the organization's smoking cessation program and the organization's mission, general operations, and smoking-related policies and practices.

Community-level information was collected in two ways: (1) interviews of community leaders representing local health departments, school boards, and juvenile justice offices, and (2) archival research of public ordinances relevant to tobacco and control policies.

Nine data files/datasets constitute the data. Datasets 1-4 contain the participant questionnaire data, carbon monoxide measurement data, and program attendance data. Dataset 5 comprises information about each program and its curriculum, some information about the community in which the program was located, and summary data about enforcement of tobacco-related ordinances. Dataset 6 contains information about about the program providers and each program delivery, including recruitment, logistics, content, and the reactions of providers and participants. Dataset 7 covers administrative aspects of the smoking cessation programs and each offering organization's mission, general operations, and smoking-related policies and norms. Dataset 8 contains information about local and state-level tobacco-related ordinances for every state and local jurisdiction where each program was located, and Dataset 9 condenses the information in Dataset 8 into one summary record for each community. The unit of observation for Datasets 1-4 is the participant, for Datasets 5 and 7 the smoking cessation program/offering organization, for Dataset 6 the program delivery/program cohort, for Dataset 8 the ordinance, and for Dataset 9 the community.

This study is part of the Seek, Test, Treat and Retain (STTR) Collaboration Project that involved over twenty studies in the fields of HIV and drug abuse. All studies were independently developed, but were chosen for the collaboration because they focused on one or more steps of the HIV treatment cascade: Seek, Test, Treat and Retain. As part of STTR Collaboration Project, the studies were grouped into Criminal Justice-related studies and Vulnerable Population-related studies. The data collected by these studies included twelve common domains (e.g., Demographic characteristics, Mental Health) in each of which a shared questionnaire or instrument was taken up by the studies and adapted to fit the study.

This study has two components.

Study #1: The main objectives of Study 1 were to determine the willingness to the community corrections community to undergo testing, and to test rapid HIV testing on-site in community corrections to referral to an off-site HIV testing location. Participants were probationers or parolees in both Providence, Rhode Island and Baltimore City, Maryland (participants split 50/50 between sites). The outcomes were undergoing HIV testing and receiving the test results.

Study #2: Randomized controlled trial of linkage to HIV care among probationers or parolees known to have HIV who were randomized to referral to treatment as usual (TAU) or Project Bridge which provided intensive case management, medical and social support. (Note: participants could "cross over" into Project Bridge at 6 months if they failed to engage with care in the TAU group.) The outcomes included retention in care, use of ART, and viral load. Assessments were done at baseline for both studies, and every 3 months thereafter until 18 months for study 2. If incarcerated, assessments were done in prison/jail.

The Services Research Outcomes Study (SROS) sought to answer questions about drug treatment efficacy and to describe client characteristics. The study was designed to provide (1) a 1990 cohort of clients to use as baseline for possible changes in treatment outcomes following increased funding to the national treatment system in the 1990s, (2) a before-to-after comparison to measure outcomes of treatment provided in 1990, (3) a follow-up of drug treatment clients five years after treatment to assess the level of sustained improvements in abstinence, and (4) a first look at multiple treatment episodes before and after treatment in a 1990 population.

Part 1 is the Facility Director Interviews and covered topics such as facility staff and organization, revenue and charges, staff hours and compensation, costs, and program characteristics.

Part 2 is the Client Records Abstractions Data, which examined the client records of 2,222 individuals discharged during 1989-1990. Information was abstracted on demographic characteristics of clients, criminal justice involvement, medical conditions, drug history including intravenous drug use, urine test results, drug treatment history, treatment services, and discharge and billing information.

Part 3 consists of the Client Follow-Up Interviews, and was conducted during 1995 and 1996. This part covered the clients' entire life span, with special attention to their behavior and circumstances during the five years before entry to the index (SROS) treatment in 1989-1990 and after leaving that treatment until the time of the interview. Additional questions were asked on patterns of alcohol and drug consumption, criminal activity, employment, health, social support, and other behavior relevant to treatment goals. Drugs included cocaine, crack, heroin, nontreatment methadone, other opiates/synthetics, barbiturates, benzodiazapine, other sedatives/hypnotics, methamphetamines, other amphetamines, marijuana/hash/THC, PCP/LSD, other hallucinogens, inhalants, over-the-counter medications, and alcohol.

The original Oregon Youth Study began 1983. The goal was to examine the etiology of antisocial behaviors in boys, with a view to designing preventive interventions within the context of the family and the school. The longitudinal study has expanded over the past few decades into an intergenerational study, retaining the original young men and including their partners and children. Demographic variables include race, religion, annual household income, and the participants' parents' employment statuses.
