Psychiatric disorders in youth in juvenile detention.

Abstract: Background Given the growth of juvenile detainee populations, epidemiologic data on their psychiatric disorders are increasingly important. Yet, there are few empirical studies. Until we have better epidemiologic data, we cannot know how best to use the system's scarce mental health resources. Methods Using the Diagnostic Interview Schedule for Children version 2.3, interviewers assessed a randomly selected, stratified sample of 1829 African American, non-Hispanic white, and Hispanic youth (1172 males, 657 females, ages 10-18 years) who were arrested and detained in Cook County, Illinois (which includes Chicago and surrounding suburbs). We present 6-month prevalence estimates by demographic subgroups (sex, race/ethnicity, and age) for the following disorders: affective disorders (major depressive episode, dysthymia, manic episode), anxiety (panic, separation anxiety, overanxious, generalized anxiety, and obsessive-compulsive disorders), psychosis, attention-deficit/hyperactivity disorder, disruptive behavior disorders (oppositional defiant disorder, conduct disorder), and substance use disorders (alcohol and other drugs). Results Nearly two thirds of males and nearly three quarters of females met diagnostic criteria for one or more psychiatric disorders. Excluding conduct disorder (common among detained youth), nearly 60% of males and more than two thirds of females met diagnostic criteria and had diagnosis-specific impairment for one or more psychiatric disorders. Half of males and almost half of females had a substance use disorder, and more than 40% of males and females met criteria for disruptive behavior disorders. Affective disorders were also prevalent, especially among females; more than 20% of females met criteria for a major depressive episode. Rates of many disorders were higher among females, non-Hispanic whites, and older adolescents. Conclusions These results suggest substantial psychiatric morbidity among juvenile detainees. Youth with psychiatric disorders pose a challenge for the juvenile justice system and, after their release, for the larger mental health system.

Prevalence of Psychiatric Disorders Among Incarcerated Women: I. Pretrial Jail Detainees

Abstract: Background: There are little epidemiologic data on psychiatric disorders of women in jails. Accurate data on female jail detainees are critical because of their increasing numbers and their unique treatment needs. Methods: Using the Diagnostic Interview Schedule, independent interviewers assessed a randomly selected, stratified sample of 1272 female jail detainees awaiting trial in Chicago, Ill. We tabulated lifetime and 6-month prevalence rates of disorders by race or ethnicity (African American, non-Hispanic white, Hispanic), age, and education and compared the jail rates with general population rates for women in the Epidemiologic Catchment Area program. We also examined whether or not psychiatric disorder was associated with the severity of the detainee's current arrest charges. Results: Over 80% of the sample met criteria for one or more lifetime psychiatric disorders; 70% were symptomatic within 6 months of the interview. The most common disorders were drug abuse or dependence, alcohol abuse or dependence, and post-traumatic stress disorder. Major depressive episode was the most prevalent major mental disorder. Rates were generally highest among non-Hispanic whites and among older detainees. Rates for all disorders were significantly higher than general population rates, except for schizophrenia. Most detainees with psychiatric disorders were arrested for nonviolent crimes. Conclusion: These results suggest substantial psychiatric morbidity among female jail detainees.

Posttraumatic Stress Disorder and Trauma in Youth in Juvenile Detention

Abstract: Objective To determine prevalence estimates of exposure to trauma and 12-month rates of posttraumatic stress disorder (PTSD) among juvenile detainees by demographic subgroups (sex, race/ethnicity, and age). Design Epidemiologic study of juvenile detainees. Master's level clinical research interviewers administered the PTSD module of the Diagnostic Interview Schedule for Children, version IV (DISC-IV), to randomly selected detainees. Setting A large, temporary detention center for juveniles in Cook County, Illinois (which includes Chicago and surrounding suburbs). Participants Randomly selected, stratified sample of 898 African American, non-Hispanic white, and Hispanic youth (532 males, 366 females, aged 10-18 years) arrested and newly detained. Main Outcome Measures Diagnostic Interview Schedule for Children, version IV. Results Most participants (92.5%) had experienced 1 or more traumas (mean, 14.6 incidents; median, 6 incidents). Significantly more males (93.2%) than females (84.0%) reported at least 1 traumatic experience; 11.2% of the sample met criteria for PTSD in the past year. More than half of the participants with PTSD reported witnessing violence as the precipitating trauma. Conclusion Trauma and PTSD seem to be more prevalent among juvenile detainees than in community samples. We recommend directions for research and discuss implications for mental health policy.

Comorbid Psychiatric Disorders in Youth in Juvenile Detention

Abstract: Objective To estimate 6-month prevalence of comorbid psychiatric disorders among juvenile detainees by demographic subgroups (sex, race/ethnicity, and age). Design Epidemiologic study of juvenile detainees. Master's level clinical research interviewers administered the Diagnostic Interview Schedule for Children Version 2.3 to randomly selected detainees. Setting A large temporary detention center for juveniles in Cook County, Illinois (which includes Chicago and surrounding suburbs). Participants Randomly selected, stratified sample of 1829 African American, non-Hispanic white, and Hispanic youth (1172 males, 657 females, aged 10-18 years) arrested and newly detained. Main Outcome Measure Diagnostic Interview Schedule for Children. Results Significantly more females (56.5%) than males (45.9%) met criteria for 2 or more of the following disorders: major depressive, dysthymic, manic, psychotic, panic, separation anxiety, overanxious, generalized anxiety, obsessive-compulsive, attention-deficit/hyperactivity, conduct, oppositional defiant, alcohol, marijuana, and other substance; 17.3% of females and 20.4% of males had only one disorder. We also examined types of disorder: affective, anxiety, substance use, and attention-deficit/hyperactivity or behavioral. The odds of having comorbid disorders were higher than expected by chance for most demographic subgroups, except when base rates of disorders were already high or when cell sizes were small. Nearly 14% of females and 11% of males had both a major mental disorder (psychosis, manic episode, or major depressive episode) and a substance use disorder. Compared with participants with no major mental disorder (the residual category), those with a major mental disorder had significantly greater odds(1.8-4.1) of having substance use disorders. Nearly 30% of females and more than 20% of males with substance use disorders had major mental disorders. Rates of some types of comorbidity were higher among non-Hispanic whites and older adolescents. Conclusions Comorbid psychiatric disorders are a major health problem among detained youth. We recommend directions for research and discuss how to improve treatment and reduce health disparities in the juvenile justice and mental health systems.

Crime Victimization in Adults With Severe Mental Illness: Comparison With the National Crime Victimization Survey

Abstract: Context Since deinstitutionalization, most persons with severe mental illness (SMI) now live in the community, where they are at great risk for crime victimization. Objectives To determine the prevalence and incidence of crime victimization among persons with SMI by sex, race/ethnicity, and age, and to compare rates with general population data (the National Crime Victimization Survey), controlling for income and demographic differences between the samples. Design Epidemiologic study of persons in treatment. Independent master’s-level clinical research interviewers administered the National Crime Victimization Survey to randomly selected patients sampled from 16 randomly selected mental health agencies. Setting Sixteen agencies providing outpatient, day, and residential treatment to persons with SMI in Chicago, Ill. Participants Randomly selected, stratified sample of 936 patients aged 18 or older (483 men, 453 women) who were African American (n = 329), non-Hispanic white (n = 321), Hispanic (n = 270), or other race/ethnicity (n = 22). The comparison group comprised 32 449 participants in the National Crime Victimization Survey. Main Outcome Measure National Crime Victimization Survey, developed by the Bureau of Justice Statistics. Results More than one quarter of persons with SMI had been victims of a violent crime in the past year, a rate more than 11 times higher than the general population rates even after controlling for demographic differences between the 2 samples ( P P Conclusions Crime victimization is a major public health problem among persons with SMI who are treated in the community. We recommend directions for future research, propose modifications in public policy, and suggest how the mental health system can respond to reduce victimization and its consequences.

Sex differences in trauma and posttraumatic stress disorder: a quantitative review of 25 years of research.

Abstract: Meta-analyses of studies yielding sex-specific risk of potentially traumatic events (PTEs) and posttraumatic stress disorder (PTSD) indicated that female participants were more likely than male participants to meet criteria for PTSD, although they were less likely to experience PTEs. Female participants were more likely than male participants to experience sexual assault and child sexual abuse, but less likely to experience accidents, nonsexual assaults, witnessing death or injury, disaster or fire, and combat or war. Among victims of specific PTEs (excluding sexual assault or abuse), female participants exhibited greater PTSD. Thus, sex differences in risk of exposure to particular types of PTE can only partially account for the differential PTSD risk in male and female participants.

Preventing Mental, Emotional, and Behavioral Disorders Among Young People: Progress and Possibilities

Abstract: This report builds on a highly valued predecessor, the 1994 Institute of Medicine (IOM) report entitled Reducing Risks for Mental Disorders: Frontiers for Preventive Intervention Research. That report provided the basis for understanding prevention science, elucidating its then-existing research base, and contemplating where it should go in the future. This report documents that an increasing number of mental, emotional, and behavioral problems in young people are in fact preventable. The proverbial ounce of prevention will indeed be worth a pound of cure: effectively applying the evidence-based prevention interventions at hand could potentially save billions of dollars in associated costs by avoiding or tempering these disorders in many individuals. Furthermore, devoting significantly greater resources to research on even more effective prevention and promotion efforts, and then reliably implementing the findings of such research, could substantially diminish the human and economic toll.
