The World Mental Health (WMH) Survey Initiative was a coordinated series of general population surveys of mental, substance use, and behavioral disorders conducted in countries across all World Health Organization (WHO) regions. The approach taken by WMH was to conduct rigorous general population surveys in nationally representative samples in many countries throughout the world, to generate data from these surveys on the prevalence, severity, course, and treatment of mental disorders. Data were collected using the WHO Composite International Diagnostic Interview (CIDI) which uses both ICD-10 and DSM-III diagnostic criteria. This survey was conducted in Nigeria and utilized the Efik, Hausa, Igbo, and Yoruba versions of the CIDI.

The original Oregon Youth Study began in 1983. The goal is 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. This longitudinal study has expanded over the past few decades into an intergenerational study, retaining the original young men and including their partners and children.

This study evaluates a comprehensive model for couples from at-risk backgrounds on the basis of a dynamic developmental systems approach and stress and support processes to examine the risk and protective impacts of romantic relationships on health in adulthood. It was posited that both general and specific developmental and relationship risks have significant implications for health outcomes in mid-adulthood. In addition, the course of intimate partner violence in early mid-adulthood is examined.

The MacArthur Mental Health Court (MHC) project is a longitudinal study examining the effectiveness of these specialty courts in reducing recidivism, reducing the number of jail days and stays, and increasing access to community mental health and substance use treatment. The study included four data collection sites (two in California, one in Minnesota, and one in Indiana), two samples (newly enrolled MHC clients and a comparison sample of offenders with mental illness in the traditional criminal justice system), two interview time points (baseline and 6-month follow-up), and the collection of objective criminal justice and court data up to 18 months post-enrollment in the MHC/post-arrest.

This study was originally published through OpenICPSR.

This project was an experimental evaluation of a collaborative partnership among the Center for Evidence-Based Crime Policy at George Mason University (CEBCP-GMU), Roanoke Police Department (RPD), Roanoke County Police Department (RCPD), Salem Police Department (SPD), and Vinton Police Department (VPD) as well as Blue Ridge Behavioral Healthcare (BRBH) in Roanoke Valley region of Virginia to conduct a place-based cluster randomized controlled trial (RCT) to evaluate the effects of the co-responder model on subsequent outcomes of individuals who were experiencing a crisis and involved in mental health-related calls for service. Responding to incidents involving individuals with mental illness has been a challenge for police officers.

While co-response teams have been embraced as an effective police response strategy, most prior evaluation studies on co-response teams focused on outcomes that are not directly related to individuals' subsequent mental health state. Additionally, the lack of experimental research hinders our ability to draw causal conclusions on the effects of co-response teams. To address this knowledge gap, this study evaluated the effectiveness of co-response teams on hospitalization outcomes of individuals in crisis using a place-based randomized controlled trial in southwest Virginia.

The NCS-2 was a re-interview of 5,001 individuals who participated in the Baseline (NCS-1). The study was conducted a decade after the initial baseline survey. The aim was to collect information about changes in mental disorders, substance use disorders, and the predictors and consequences of these changes over the ten years between the two surveys. The collection contains four major sections: the main survey, demographic data, diagnostic data, and state, county, and tract FIPS data.

In the main survey, respondents were asked about general physical and mental health. Questions focused on a variety of health issues, including limitations caused by respondents' health issues, substance use, childhood health, life-threatening illnesses, chronic conditions, medications taken in the past 12 months, level of functioning and symptoms experienced in the past 30 days, and any services used by the respondents since the (NCS-1). Additional questions focused on mental disorders including depression, bipolar disorder, specific and social phobias, generalized anxiety, intermittent explosive disorder, suicidality, post-traumatic stress disorder, neurasthenia, pre-menstrual dysphoric disorder, attention deficit/hyperactivity disorder, oppositional defiant disorder, conduct disorder, and separation anxiety. Respondents were also asked about their lives in general, with topics including employment, finances, marriage, children, their social lives, and stressful life events experienced in the past 12 months. Additionally, two personality assessments were included consisting of respondents' opinions on whether various true/false statements accurately described their personalities. Another focus of the main survey dealt with substance use and abuse, nonmedical use of prescription drugs, and polysubstance use. Interview questions in the NCS-2 Main Survey were customized to each respondent based on previous responses in the Baseline (NCS-1).

The second part contains demographic and other background information including age, education, employment, household composition, household income, marital status, and region.

The third part focuses on whether respondents met diagnostic criteria for psychological disorders asked about in the main survey.

The fourth part contains respondents' state, county, and tract FIPS data.

This randomized controlled trial evaluated a culturally appropriate intervention to improve the recognition and treatment of depression among Asian and Latino American primary care patients at Massachusetts General Hospital (MGH), using a culturally focused psychiatric (CFP) consultation with a team of mental health providers who were bilingual/bicultural, trained in culturally competent techniques, and familiar with the cultures and languages of the patients served. Targeted minority patients who screened positive for clinical depression were eligible to participate in the trial. The intervention patients were offered the CFP consultation at baseline and, if eligible, received the CFP patient toolkit as part of their treatment. The toolkit provided psychoeducation and tools for managing depression as well as information on community resources. The usual care patients were offered standard referrals to MGH mental health resources.

Questionnaires were administered to the patients at screening, baseline, two-week follow-up, and six month follow-up. The screening questionnaires included the two-item Public Health Questionnaire (PHQ-2) and demographic questions. Assessment measures administered to the intervention patients at baseline included the Mini International Neuropsychiatric Interview (MINI), Quick Inventory of Depressive Symptomatology-Self Rated Scale (QIDS-SR 16), Global Assessment of Functioning (GAF), Schwartz Outcome Scale (SOS-10), and a demographic questionnaire and resource utilization questionnaire. At six month follow-up, the intervention arm was administered a resource utilization questionnaire, patient satisfaction questionnaire (Treatment Satisfaction Scale), qualitative interview, and the QIDS-SR 16 and SOS-10. The SOS-10 was also administered to the intervention patients at two-week follow-up. In the usual care arm, the QIDS-SR 16 and resource utilization questionnaire was administered at baseline and six months, the qualitative interview at six months, and the demographic questionnaire at baseline or six-months. There was no two-week assessment for the usual care patients. Electronic medical record review was used for both arms at baseline and six months, as needed. In addition, qualitative interviews were conducted with project and practice staff at the end of the study.

The data file includes the responses to the questionnaires and variables describing the CFP consultation assessment (DSM-IV Axis I, II, III, IV, and V diagnoses), treatment recommendations made to the patients' primary care physicians (PCPs) after the CFP consultation, and study staff contacts with the patients' PCPs and mental health providers. ICPSR did not receive the data from the qualitative interviews or electronic medical record reviews.

The National Comorbidity Survey Replication Adolescent Supplement (NCS-A) was designed to estimate the lifetime-to-date and current prevalence, age-of-onset distributions, course, and comorbidity of DSM-IV disorders in the child and adolescent years of life among adolescents in the United States; to identify risk and protective factors for the onset and persistence of these disorders; to describe patterns and correlates of service use for these disorders; and to lay the groundwork for subsequent follow-up studies that can be used to identify early expressions of adult mental disorders.

The core NCS-A interview schedule was an adaptation of the World Health Organization Composite International Diagnostic Interview (CIDI). NCS-A also administered the non-verbal subtest (Matrices subtest) of the Kaufman Brief Intelligence Test (K-BIT).

In addition to interviewing adolescents, information was collected from a parent or a parent surrogate to obtain an additional perspective on the adolescent's mental health and its correlates. Information from parents focused on the five adolescent disorders for which previous methodological research has most consistently shown that parental reports are important for making diagnoses: attention-deficit/hyperactivity disorder, conduct disorder, oppositional defiant disorder, major depressive episode, and dysthymic disorder.

Demographic information collected by NCS-A includes age, citizenship status, country of birth, criminal history, ethnicity, grandparents' country of birth, language(s) spoken in the home, parents' country of birth, race, religion, and sex.

The data collection contains six data files: (1) data for the adolescent household and school respondents; (2) data for the parents who responded to the long self-administered questionnaire; (3) data for the parents who responded to both the long self-administered questionnaire and short telephone interview; (4) diagnostic variables derived from the data collected from the adolescents and parents; (5) K-BIT scores normed to the NCS-A adolescent sample; and (6) raw K-BIT data.

This study addressed whether it is better to expand the scope of collaborative care programs to treat patients with more complex psychiatric disorders or to facilitate successful referrals to specialty mental health care. The primary objective of this study is to compare Telepsychiatry Collaborative Care (TCC) and Telepsychiatry Enhanced Referral (TER) from the patient and provider perspective. The secondary objective is to determine whether patients not engaging and responding to TER, improve with Phone-Psychiatry Enhanced Referral (PER). There are four specific aims.

Aim #1: To quantitatively compare the treatment experience, engagement, self-reported clinical outcomes, and recovery-oriented outcomes of patients initially randomized to TCC and TER.

Aim #2: For the subset of patients randomized to TER who do not engage in treatment and are still symptomatic at 6 months, quantitatively compare treatment experience, treatment engagement, self-reported clinical outcomes and recovery-oriented outcomes of patients randomized to continued-TER or PER.

Aim #3: To gain an in-depth understanding of patients' and providers' treatment experience, qualitatively compare those randomized to TCC, TER and PER.

Aim #4: To examine treatment heterogeneity among subgroups of patients randomized to TCC and TER based on race/ethnicity, age and clinical severity.

The study National Survey of American Life: Multi-Generational and Caribbean Cross-Section Studies also known as the Family Connections Across Generations and Nations is a follow-up to the National Survey of American Life (NSAL): Coping With Stress in the 21st Century, the baseline study which interviewed 6,200 adults and 1,200 adolescents in households of African Americans, non-Hispanic Whites, and Blacks of Caribbean descent.

This study examines influences of family life on people's satisfaction with their lives and their health and general well-being. Specifically, it investigates family and inter-generational processes, with a special emphasis on contextual and structural influences on relationships as they affect individual and family health and well-being across, and within, ethnically and nationally diverse population samples.

Categories of variables include sections on neighborhood, health, social support, depression, social support, mental health episodes (such as depression and mania), substance use, tobacco use, discrimination, and interviewer observations. Demographic variables include the race and ethnicity of the respondent and their spouse, racial background of parents, education, employment, volunteerism, and family income.

This study contains data from the fifth follow-up interview of the Northwestern Juvenile Project (NJP), a longitudinal assessment of alcohol, drug, or mental service treatment needs of juvenile detainees. The fifth follow-up occurred approximately 6 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, and 296 non-Hispanic white respondents. Participants were tracked from the time they left detention. All participants were eligible for the fifth follow-up interview. 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.

This project was a mixed-method, multi-level study of low income families of children with special needs and the system which served them, focusing primarily on child care, employment, and balancing work and family. This approach included an analysis of existing national and state-level data sets, statewide surveys of parents and child care providers, and a field study to look at these issues at the local level in three selected communities in the state of Maine: Portland, Lewiston/Auburn, and Presque Isle. While the primary focus was on access to child care, this project also looked at the related issues of welfare reform, the impact of work force participation on having a child with special needs, and the issue of coordination of early intervention services with the child care system. The goal was to understand better the issues facing low income families with special needs children across the programs and policies affecting their employment, access to child care, and meeting the special needs of their children. In the first year of the study, qualitative research was conducted to learn directly from parents about their experiences. In the second and third years, a field study of three communities was conducted as well as statewide surveys and analysis of national data bases to supplement the data collected in the first year. This data collection is comprised of the two quantitative data files produced during the second and third years of the study which are described in more detail below.

Child Care Provider Survey: The Child Care Provider Survey was a statewide survey of child care providers selected at random from the list of licensed providers in Maine given by the state licensing agency. Questions focused on the perspective of child care providers on the issues of access and inclusion that parents raised.

Parent Survey: The Parent Survey was a statewide survey of parents and children aged 0-18 years with diagnosed special needs (enrolled in Maine Care - Katie Beckett and Title V eligibility groups - and Child Development Services early intervention caseloads). Questions focused on child care utilization and work experiences in relation to children with special needs.

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.

This study contains data from a combination of 27 in-depth interviews and 133 surveys from a randomly-selected sample of traditional healers living and working in rural, northeastern South Africa. Participating healers were primarily female (77%), older in age (median: 58.0 years) with very little formal education (median: 3.7 years) and had practiced traditional medicine for many years (median: 17 years).

The interviews were conducted to identify treatment practices of mental, neurological, and substance abuse (MNS) disorders.

This study created the largest and most comprehensive database ever created to date on lone wolf terrorism. It includes 1 Excel data file (LONEWOLF_NIJ_HAMM_SPAAIJ_2014_unlocked.xlsx; n=98, 23 variables). The information was gathered from an extensive review of previous research, biographies and memoirs, journalistic sources, government reports, court documents, encyclopedias and documentary films.

Qualitative interviews were conducted as part of this research, but these interviews were not made available for archiving.

The Epidemiologic Catchment Area (ECA) program of research was initiated in response to the 1977 report of the President's Commission on Mental Health. The purpose was to collect data on the prevalence and incidence of mental disorders and on the use of and need for services by the mentally ill. Independent research teams at five universities (Yale University, Johns Hopkins University, Washington University, Duke University, and University of California at Los Angeles), in collaboration with the National Institute for Mental Health, conducted the studies with a core of common questions and sample characteristics. The sites were areas that had previously been designated as Community Mental Health Center catchment areas: New Haven, Connecticut, Baltimore, Maryland, St. Louis, Missouri, Durham, North Carolina, and Los Angeles, California. Each site sampled over 3,000 community residents and 500 residents of institutions, yielding 20,861 respondents overall. The longitudinal ECA design incorporated two waves of personal interviews administered one year apart and a brief telephone interview in between (for the household sample). The diagnostic interview used in the ECA was the NIMH Diagnostic Interview Schedule (DIS), Version III (with the exception of the Yale Wave I survey, which used Version II). Diagnoses were categorized according to the DIAGNOSTIC AND STATISTICAL MANUAL OF MENTAL DISORDERS, 3rd Edition (DSM-III). Diagnoses derived from the DIS include manic episode, dysthymia, bipolar disorder, single episode major depression, recurrent major depression, atypical bipolar disorder, alcohol abuse or dependence, drug abuse or dependence, schizophrenia, schizophreniform, obsessive compulsive disorder, phobia, somatization, panic, antisocial personality, and anorexia nervosa. The DIS uses the Mini-Mental State Examination (MMSE), which measures cognitive functioning, as an indirect measure of the DSM-III Organic Mental Disorders. In the ECA survey, this diagnosis is called cognitive impairment.

This collection features data from 17,327 participants across 2,005 variables. Data from the Los Angeles, California, Catchment (UCLA) are not included. Baseline data (Wave 1) and Wave 2 data were linked to the National Death Index through 2007, which includes primary and contributing causes of death, International Classification of Disease (ICD) codes, and nature of injury variables.

The Johns Hopkins University Prevention Research center - Risks for Transitions, Baltimore city, 2008-2011 study (JHU PRC Risks for Transition in Drug Use among Urban Adults) represents data collected for a 25 years follow-up from the original JHU PRC study. At the start of the data collection, a cohort of 2,311 youth were randomly assigned to two classroom-based universal preventive interventions implemented in 43 classrooms of 19 public schools located in 5 socio-demographically distinct areas in Eastern Baltimore. This collection includes data from 1,434 respondents from the original cohort collected in 2008-2012. The mean age of the respondents was 30-32 years old.

Psychopathology (major depressive episode, phobia and anxiety disorders) was assessed using modules from the Composite International Diagnostic Interview-University of Michigan Version, CIDI- UM (WHO, 1997). An antisocial symptom scale adapted from the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC) was administered which consisted of 30 questions that assessed behaviors experienced since turning 18 years of age. The alcohol, tobacco and drug modules of the interview were modeled after NESARC Alcohol Use Disorder and Associated Disabilities Interview Schedule-IV. Types of information in these modules collected include age of onset, use in past year and prior past year, frequency and recency of use, and DSM-IV abuse and dependence criteria. Socioeconomic status indicators, variables on education, employment, marital status, parenthood, social supports, family history of mental health and drug problems, general health, treatment utilization, and life events are included in this dataset.

This dataset includes 3,140 variables.

The National Survey of American Life Adolescent Supplement (NSAL-A), 2001-2004, was designed to estimate the lifetime-to-date and current prevalence, age-of-onset distributions, course, and comorbidity of DSM-IV disorders among African American and Caribbean adolescents in the United States; to identify risk and protective factors for the onset and persistence of these disorders; to describe patterns and correlates of service use for these disorders; and to lay the groundwork for subsequent follow-up studies that can be used to identify early expressions of adult mental disorders. In addition and similar to the NSAL adult dataset (Collaborative Psychiatric Epidemiology Surveys (CPES), 2001-2003 [United States] (ICPSR 20240)), the adolescent dataset contains detailed measures of health; social conditions; stressors; distress; racial identity; subjective, neighborhood conditions; activities and school; media; and social and psychological protective and risk factors. Numerous variables from the adult dataset have been merged into the adolescent dataset, as the NSAL adult and adolescent respondents reside in the same households. Some of these variables apply to the entire household (i.e. region, urbanicity, and family income), while others apply specifically to the NSAL adult respondent living in the adolescent's household (i.e. adult years of education, adult marital status, and adult nativity [foreign-born vs. US born]). The immigration measures were asked of Caribbean black adult respondents only. No comparable measures assess the immigration and generational status of the Caribbean black adolescent respondents. The adult dataset measures are merged into the adolescent dataset to assist in approximating these measures for adolescent respondents. The NSAL adolescent dataset also includes variables for other non-core and experimental disorders. These include tobacco use/nicotine dependence, premenstrual syndrome, minor depression, recurrent brief depression, hypomania, and hypomania sub-threshold. Demographic variables include age, race and ethnicity, ancestry or national origins, height, weight, marital status, income, and education level.
