Health Disparities & Public Policy is a research program in the Department of Psychiatry and Behavioral Sciences, Feinberg School of Medicine, Northwestern University. Formerly known as the Psycho-Legal Studies program, the research group changed its name to reflect its focus on health disparities. The program’s studies investigate health needs of traditionally underserved populations such as racial/ethnic minorities, impoverished persons, the homeless, and incarcerated populations. Findings from the group’s studies have shaped US public health policy. Results have been cited in Supreme Court amicus briefs, congressional hearings, and Surgeon General’s reports. The program has conducted studies in the following areas:
- The criminalization of persons with psychiatric disorders
- Prevalence of psychiatric disorders in adult jail detainees
- Development and persistence of psychiatric disorders in youth while they are incarcerated and after they return to their communities
- Long-term outcomes of delinquent youth after detention
- Victimization among persons with psychiatric disorders
- Patterns of service utilization in high-risk populations
- The relationship between psychiatric disorders and violence
- Trajectories of substance use disorders
- Patterns of incarceration and how they affect health disparities in psychiatric disorders and physical illnesses such as HIV/AIDS
- Mortality rates, focusing on variables associated with early violent death
The Northwestern Juvenile Project
The Northwestern Juvenile Project is currently the program’s primary focus. Begun in 1995, it is the first large-scale longitudinal study of the mental health needs and outcomes of delinquent youth. We enrolled 1829 randomly-selected youth, 1172 males and 657 females, as they entered the Cook County Juvenile Temporary Detention Center from 1995 to 1998. The sample is diverse: 1005 African Americans, 524 Hispanics, 296 non-Hispanic whites, and 4 of other race/ethnicity. Funded by a consortium of federal agencies and private foundations (e.g., NIH, DOJ, CDC, Robert Wood Johnson Foundation), we have been tracking and re-interviewing these youth since November 1998. Unlike many studies that drop participants if they are incarcerated at follow-up, we re-interview our participants wherever they are living when their interview is due. Thanks to the cooperation of many agencies in Chicago, Cook County, and the State of Illinois, the study retained 81.6% of participants still living at the 16-year follow-up. The longitudinal study provided data never before available on varied topics such as the persistence of substance use disorders; the prevalence and persistence of psychiatric disorders; comorbidity; and variables predicting early violent death.
Goals of the Study
- To assess the development and persistence of alcohol, drug, and mental disorders as delinquent youth age. We also study patterns of comorbidity, associated functional impairments, and related outcomes.
- To determine pathways and patterns of drug use, violence, and other behaviors such as HIV/AIDS risk. We examine the development of these risky behaviors among our subjects, focusing on gender differences, racial/ethnic differences, the antecedents of these behaviors, how these behaviors are interrelated, and how incarceration affects behaviors and the development of psychiatric disorders over time.
How Is the Northwestern Juvenile Project Unique?
Many studies have investigated general population youth to see who becomes delinquent. Far fewer studies examine health needs and outcomes among youth already in the juvenile justice system. We study delinquent youth because they are at such a high risk for psychiatric disorders, life-threatening problem behaviors, HIV/AIDS, and premature violent death. Our longitudinal data allow us to examine fundamental questions not possible in cross-sectional studies. For example: What are the most common patterns of comorbid disorders? Which variables predict the sequence of disorders as youth age? How do HIV/AIDS risk behaviors (e.g., unprotected sex, trading sex for drugs, needle-risk behaviors) develop over time? How do patterns of incarceration affect drug abuse and HIV/AIDS risk behaviors in adulthood? Our findings help guide the development of intervention strategies for delinquent youth and incarcerated young adults.
The Northwestern Victimization Project
Begun in 1995, the Northwestern Victimization Project was the first large-scale, longitudinal study of crime victimization patterns in severely mentally ill persons living in the community. Prior studies of violence and mental disorder had focused on perpetration, not victimization. We examined the rates, risk factors, and patterns of crime victimization in 936 persons with chronic severe mental disorders. More than one-quarter of the sample had been victims of a violent crime in the past year, a rate more than 11 times higher than general population rates, even after controlling for demographic differences between the two samples. The Northwestern Victimization Project has been replicated in the Netherlands and other countries, where public health officials now realize that victimization of persons with severe mental illnesses is a far more serious threat to public health than the perpetration of violence.
Psychiatric Disorders in Male and Female Adult Jail Detainees
The Health Disparities and Public Policy program conducted the first large-scale epidemiologic studies of psychiatric disorders among male and female adult jail detainees. Between 1983 And 1995, a series of investigations examined (1) the prevalence of psychiatric disorders in jail detainees, and (2) whether detainees who had severe mental illnesses received treatment while in jail. Our findings highlight the discrepancy between jail detainees’ need for mental health services and the services that they receive. The data showed that of male detainees who needed psychiatric services, only 37 percent received them. Only 20 percent of female detainees who needed psychiatric services received them. Because jails were never intended to be psychiatric hospitals, few have the resources necessary to adequately treat the increasing numbers of detainees entering jails nationwide. Our findings demonstrated that jails must systematically screen detainees upon admission, provide treatment during their stay, and refer them for services after they are released.
Consequences of deinstitutionalization: The police as streetcorner psychiatrist
Incarceration of persons with psychiatric illnesses disproportionately affects minorities, who are least likely to be able to afford mental health care. In an observational study of police officers, our findings showed that mentally ill persons had an arrest rate nearly double that of non-mentally ill persons. Police reluctantly arrested mentally ill persons when a mental health evaluation and treatment would have been preferable but was not available. The findings suggested that reduced community services had resulted in mentally ill persons being “criminalized”; for many, arrest had supplanted hospitalization. The findings supported the thesis, set forth by public health experts, that for poor persons—especially racial/ethnic minorities—arrest and incarceration had become the entrée for receiving mental health services. The findings of this study were cited in amicus briefs to the Supreme Court, were used in many hearings by Congress, and highlighted the need for special diversion programs for mentally ill persons in the criminal justice system.
