The objectives of this study were (1) to compare long-term patterns of violent crime for mentally disordered patients and for prison inmates, and (2) to evaluate the predictive validity of a diagnosis of schizophrenia for subsequent arrests for violent crimes. For purposes of this data collection, violent crimes were defined as including murder, manslaughter, rape, assault, kidnapping, and sodomy. The study analyzed individual state mental hospital patients and inmates of state prisons in New York State over a 20-year span. In the process of obtaining information regarding the individuals, three different areas were focused on: hospital, incarceration, and arrest histories. Variables for hospital histories include inpatient hospitalizations, admission and discharge dates, legal status for all state hospitals through 1988, primary diagnosis for target and most recent admissions, and placements in New York State Department of Correctional Services mental hospitals. Incarceration history variables include time spent in adult state prisons, incarcerations through 1988, and dates of release (including re-entry to community on parole, outright release, or escape). Arrest histories include information on the subject's first adult arrest through 1988 (only the most serious charge for each incident is recorded) and out-of-state arrests, when available. Demographic variables include age, race, and date of birth.

This study investigates the relationship between mental disorder and violent behavior. Detailed interviews were conducted with inmates in the North Carolina prison system. Each respondent was given a psychological assessment using the Diagnostic Interview Schedule, Version III. Conditions of particular interest were schizophrenia, mood disorders (depression and dysthymia), traumatic stress disorder, and alcohol disorders. The data supply information on the respondent's criminal history, psychological status at the time of interview, and history of rule infractions while incarcerated for the current offense. In addition to the psychological assessment, questions were also asked covering areas of general health status, criminal history, and drug and alcohol use. Demographic information includes age, education, marital status, and race.

The primary objective of this project was to explore the familial, physical, psychological, social, and cultural antecedents and correlates of violent criminal offending. This research used an extensive longitudinal database collected on 1,345 young adult male offenders admitted to the Federal Correctional Institution (FCI) in Tallahassee, Florida, from November 3, 1970, to November 2, 1972. Using FBI arrest records ("rap sheets"), each inmate was classified on the basis of the National Crime Information Center Uniform Offense Codes into one of four distinct categories: (1) "angry violent," in which the apparent goal was to injure the victim, (2) "instrumentally violent," in which the aggressive behavior was a means to an end (as in a robbery), (3) "potentially violent," as evidenced by making threats or carrying weapons but in which the offender was not accused of any violent offenses, and (4) "nonviolent," in which the offender had not been charged with violent criminal behavior. Violent offenders were also subdivided into those who had been repetitively violent and those who had been charged with just one violent offense. As part of the classification process, each inmate was administered an extensive battery of tests by the research project staff. The two primary personality assessment instruments utilized were the Minnesota Multiphasic Personality Inventory (MMPI) and the California Psychological Inventory (CPI). Each inmate's caseworker filled out a series of of standard Bureau of Prisons forms recording the results of the medical, educational, and psychological evaluations, as well as salient aspects of the case and criminal history. The researchers also obtained copies of each offender's Presentence Investigation Report (PSI) that had been prepared by the federal probation officer, and then devised a series of scales to quantify the PSI data. In addition, an hour-long structured intake interview was administered to each inmate by his team psychologist. Global scales were constructed from these intake interviews. After each interview, the psychologists performed an evaluative Q-sort. Nine scales were later constructed based on these Q-sorts. Also, every dormitory officer and every work supervisor completed scales assessing each subject's interpersonal adjustment and work performance at 90-day intervals. Immediately prior to release, as many inmates as possible were reinterviewed and retested on the MMPI and the CPI. Follow-ups using FBI rap sheets were conducted in 1976 and 1984. Variables obtained from the Bureau of Prisons forms include age upon entry, race, marital status, age at first arrest, number of prior adult convictions, commitment offense(s), highest school grade completed, drug dependency, and alcoholism. Scales developed from the PSIs provide data on father, mother, and siblings, family incohesiveness, adequacy of childhood dwelling, social deviance of family, school problems, employment problems, achievement motivation, problems with interpersonal relations, authority conflicts, childhood and adolescent or adult maladjustment and deviance, poor physical health, juvenile conviction record, adult arrest and conviction record, violence of offense, group influence on illegal behavior, and prior prison adjustment. The intake interview inquired about the developmental family history and the child's development, the inmate's marriage, educational, and work history and attitudes, attitudes toward sex, military service and attitudes, self-reported use of alcohol and other substances, religious preferences and practices, and problems during any previous confinements. Scales based on the psychologists' Q-sorts evaluated aggression, hostility avoidance, authority conflict, sociability, social withdrawal, social/emotional constriction, passivity, dominance, and adaptation to the environment. Data are also provided on global dorm adjustment and the number of shots, cell house days, sick calls, and infractions for the

The purpose of the study was to investigate the criminal career patterns of violent offenders. These data are intended to facilitate the development of models to predict recidivism and violence, and to construct parole supervision programs. Original data were collected on young male offenders in 1964 and 1965 as they entered the California Youth Authority (CYA). At this time, data were collected on criminal history, including current offenses, drug and alcohol use, psychological and personality variables, and sentencing, and demographics such as age, education, work experience, and family structure. The data collection also contains results from a number of standardized psychological instruments: California Psychological Inventory, Minnesota Multiphasic Personality Inventory, California Achievement Test Battery, General Aptitude Test Battery, Army General Classification Test, and the Revised Beta Test. After release from the CYA and over the following 20 years, subsequent arrest information was collected on the offenders, including the nature of the offense, disposition, and arrest and parole dates.

The purpose of this data collection was to explore the relationship between crime and mental disorder among jail inmates. Three sample groups were studied: jail inmates who had psychiatric contacts, jail inmates who did not have psychiatric contacts, and a control group of psychiatric patients who were not in jail. Psychiatric diagnosis history for inmates and patients with psychiatric contacts spanning 18 years (1960-1977) is available along with each subject's crime record and sentencing history. Variables include demographic characteristics, type of offenses sentenced, and number of arrests. Also included are psychiatric contact information including date of contact, diagnosis, type of service given, date of treatment termination, and reason for termination.

The National Consortium for Assessing Drug Control Initiatives, funded by the Bureau of Justice Assistance and coordinated by the Criminal Justice Statistics Association, collected drug offender processing data from the state of New York. The purpose of the project was to track adult drug offenders from the point of entry into the criminal justice system (typically by arrest) through final court disposition, regardless of whether the offender was released without trial, acquitted, or convicted. These data allow researchers to examine how the criminal justice system processes drug offenders, to measure the changing volume of drug offenders moving through the different segments of the criminal justice system, to calculate processing time intervals between major decision-making events, and to assess the changing structure of the drug offender population. For purposes of this project, a drug offender was defined as any person who had been charged with a felony drug offense. The data are structured into six segments pertaining to (1) record identification, (2) the offender (date of birth, sex, race, and ethnic origin), (3) arrest information (date of arrest, age at arrest, arrest charge code), (4) prosecution information (filed offense code and level, prosecution disposition and date), (5) court disposition information (disposition offense and level, court disposition, final disposition date, final pleading, type of trial), and (6) sentencing information (sentence and sentence date, sentence minimum and maximum). Also included are elapsed time variables. The unit of analysis is the felony drug offender.

This data collection effort examined the influence of drug use on three key aspects of offenders' criminal careers in violence: participation, frequency of offending, and termination rate. A random sample of arrestees was taken from those arrested in Washington, DC, during the period July 1, 1985, to June 6, 1986. The sample was stratified to overrepresent groups other than Black males. Drug use was determined by urinalysis results at the time of arrest, as contrasted with previous studies that relied on self-reports of drug use. The research addresses the following questions: (1) Does drug use have an influence on participation in violent criminal activity? (2) Does drug use influence the frequency of violent offending? (3) Is there a difference in the types and rates of violent offending between drug-using offenders who use stimulants and those who use depressants? Variables regarding arrests include date of arrest, drug test result, charges filed, disposition date, disposition type, and sentence length imposed. Demographic variables include race, sex, birthdate, and place of birth.

This data collection was designed to estimate the extent and variation of individual offending by crime type, race, age, and prior criminal record. Included in this collection are the criminal records of individuals aged 16 years or older who were arrested in the state of New York. Two separate data files are supplied. Part 1 contains data on all adults arrested in New York from 1972 to 1976 for rape, murder, robbery, aggravated assault, or burglary. Part 2 includes data on all adults arrested for larceny or auto theft in Albany and Erie counties. Variables include items such as sex, race, age, number of prior arrests, date and place of arrest, arrest charged, number of multiple counts, court disposition of charges, and type and length of sentence.

This data collection was undertaken to develop a typology of narcotic addicts according to the kind, frequency, and seriousness of their crimes and to identify the most serious criminal offenders, thereby determining which individuals were best suited to rehabilitation. The following questions are addressed by the data: (1) What "types" of narcotic addicts can be distinguished in terms of their criminal behavior? Which of these types are amenable to rehabilitation? (2) At what time during their addiction careers do addicts commit the most crime? Do narcotic addicts "mature" out of addiction? (3) What is the relationship between individuals' involvement in crime prior to addiction and their criminal activity and drug use over their addiction career? (4) Which demographic, personality, or other factors are associated with serious crime committed during periods of narcotic addiction? (5) What are the contributions of situational and dispositional factors to the relationship between addiction and crime? Part 1 of the collection details the subjects' addiction careers, the age they first used various drugs, the age they first became addicted to narcotics, the amount of time they were addicted/not addicted to narcotics, and the total length of their addiction careers. Part 2 contains variables generated by cluster analysis, including cluster assignment or "type." Part 3 includes the educational, occupational, and arrest histories of the subjects, as well as the drug use and arrest histories of their families. The Part 4 file consists of Minnesota Multiphasic Personality Inventory and Raven Progressive Matrix scores. The frequency and types of crime that subjects committed during the preaddiction period comprise Part 5, while the frequency and nature of drug use during the preaddiction period comprise Part 6. Parts 7 and 8 contain crime variables and drug use variables, respectively, across all nonaddiction periods. Finally, Part 9 contains data characterizing crime across all addiction periods, and Part 10 contains variables regarding drug use across total addiction periods.
