Assessing the Texas Christian University Drug Screen Instrument with Texas Department of Criminal Justice Inmates, 1999-2000 (ICPSR 3541)
Released/updated on: 2003-06-05
Geographic coverage: United States, Texas
Time period: 1999-01-01--2000-01-01
The overall purpose of this study was to examine the psychometric properties and credibility of the Texas Christian University (TCU) Drug Screen as an instrument to assess drug use severity for treatment referral decisions in correctional settings. TCU Drug Screen data were collected on 18,364 Texas Department of Criminal Justice (TDCJ) inmates (15,816 males and 2,548 females) who completed the screen between January 1 and April 30, 1999. Of the 18,364 subjects, 13,902 were Institutional Division (TDCJ-ID) inmates and 4,462 were State Jail Division (TDCJ-SJD) inmates. The TCU Drug Screen was administered by TDCJ staff almost exclusively in a small group setting (12-25 inmates per group) as part of a larger battery of assessments during the intake process at a TDCJ facility. The level and intensity of treatment services needed was then determined and a referral decision was made. As part of this study, the relationship between TCU Drug Screen information and post-release reincarceration was examined. Although one original goal in the study was to assess the comparability, or concurrent validity, of the TCU Drug Screen with the lengthier, more comprehensive Addiction Severity Index (ASI), TDCJ changed the administration protocol for the ASI so that it was given only to a subsample of 3,245 inmates who failed to disclose drug use problems on the TCU Drug Screen. The data include inmate responses to all items of the TCU Drug Screen and the overall drug screen score. There is also demographic information as well as incarceration, release, and reincarceration data.

Consequences of Childhood Exposure to Intimate Partner Violence in Chicago, Illinois, 1994-2000 (ICPSR 20344)
Released/updated on: 2008-04-15
Geographic coverage: United States, Chicago, Illinois
Time period: 1994-01-01--2000-01-01
This study used data from the first two waves of the Project on Human Development in Chicago Neighborhoods (PHDCN) to analyze the consequences of childhood exposure to intimate partner violence. The researcher for this study attempted to make four contributions: (1) provide theory driven research in the field of intimate partner violence, (2) do practical research, (3) strike a balance between the resolution of measurement problems and the examination of concrete outcomes, and (4) use high quality data and advanced statistical techniques to adjudicate between conflicting findings in existing literature. The nine data files used in this study were drawn from multiple imputed iterations using the Expectation-Maximization (E.M.) algorithm and data augmentation to address missing data. They included data from two waves of the PHDCN, with 4,955 records for each wave. The data included information for subjects aged 0 to 18 and covered the years 1994 to 2000. The researcher used various scales to measure domestic violence exposer, the impact of exposure on the child's cognitive functioning, the behavioral impact of exposure to domestic violence, anxiety, and the parent-child relationship. Data include the variables that the researcher used to study the effect of domestic violence exposure on not only externalizing, internalizing, and total behavior problems, and academic and cognitive ability, but also truancy, grade repetition, and drug use. This study also contains a selection of variables from several PHDCN studies including those pertaining to intimate partner violence, child abuse, juvenile delinquency, deviance of peers, alcohol use, primary caregiver involvement in the subject's life, and demographics.

Project on Human Development in Chicago Neighborhoods (PHDCN): Addendum (Young Adult), Wave 3, 2000-2002 (ICPSR 13671)
Released/updated on: 2007-02-22
Geographic coverage: United States, Chicago, Illinois
Time period: 2000-01-01--2002-01-01
The Project on Human Development in Chicago Neighborhoods (PHDCN) was a large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. For subjects included in Wave 3 but not in Wave 2, an addendum interview was administered consisting of measures or portions of measures from the Wave 2 interview. This included questions from PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): MY EXPOSURE TO VIOLENCE (SUBJECT), WAVE 2, 1997-2000 (ICPSR 13617), PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): HOUSEHOLD COMPOSITION, WAVE 2, 1997-2000 (ICPSR 13628), PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): HEALTH SCREEN, WAVE 2, 1997-2000 (ICPSR 13629), PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): LANGUAGE SCREEN, WAVE 2, 1997-2000 (ICPSR 13634), PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): SUICIDE INTERVIEW, WAVE 2, 1997-2000 (ICPSR 13660), and PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): WECHSLER ADULT INTELLIGENCE SCALE-REVISED, WAVE 2, 1997-2000 (ICPSR 13663).

Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. Traditionally, the Stanford-Binet (SB) Intelligence Scale was a wide-range individual test, assessing intelligence from age two through the superior adult level. It was an age scale, requiring subjects to solve problems, give definitions, memorize new material, and use some visual-motor skills at various age levels. For this study, the SB included a vocabulary subtest consisting of providing both names of pictures and definitions of words. It was only administered to Cohort 3.

Towards Commercialization: Preliminary Developmental Validation of a High Resolution Melt Curve Mixture Prediction Assay and SVM Tool, Virginia, 2020-2022 (ICPSR 39133)
Released/updated on: 2024-08-28
Geographic coverage: United States, Virginia
Time period: 2020-01-01--2022-01-01
In the current study, roughly 170 single source samples and 32 two-person mixture samples were tested using both the integrated Quantiplex®-high resolution melt (HRM) assay and Quantifiler™ Trio-HRM assay, then the entire HRM datasets were exported for prediction modeling using both linear discriminate analysis (LDA) and support vector machine (SVM) algorithms in R Studio software. For proof-of-concept, only 8 different genotypes, including a genotype of "mixture", were represented (for each locus) in testing. A portion of the samples tested were used to "train" the software and the remaining sample data was used as unknowns (or "validation") samples for prediction. When samples were tested in the Quantiplex®-HRM assay, an overall accuracy of 87.88 percent was exhibited, correctly classifying 87.5 percent of single source samples as such and 90 percent of mixture samples. Similarly, when samples were tested in the Quantifiler™ Trio-HRM assay an overall accuracy of 79.2 percent was exhibited, with 89.2 percent of single source samples accurately classifying and 43.8 percent of mixtures accurately classifying. Additionally, quantification values obtained from the integrated assays as well as the quality metrics such as the slope, R2, and y-intercept, were not significantly different than those obtained in the standard assays.
