The Value and Validity of Self-Reported Survey Data on the Rape Experiences of College Students.

Self-reported survey data on the extent and nature of rape and sexual assault experienced by a population represent an important source of information because these crimes often go unreported, and are thus undercounted in law enforcement or other official statistics. This article compares Campus Climate Survey Validation Study (CCSVS) data to Clery Act data in an effort to (1) assess the validity of the CCSVS data the Clery Act data based on the extent to which they corroborate one another, and (2) estimate the extent to which Clery Act data potentially underestimate the true incidence of rape. The results help to establish the extent to which self-report surveys on sexual victimization are needed to understand the magnitude of the problem among a given population.

Using Interteaching to Promote Online Learning Outcomes.

Due to the COVID-19 pandemic, educators have been forced to rapidly transition away from in-person learning environments to completely online formats. Many of these educators have had little or no training and experience teaching online, contributing to stress and anxiety. To compound this problem even further, there are a multitude of online learning technologies from which to choose that can be relatively costly and require an intensive production process.

Methods for Improving Representativeness in a Web Survey on Sexual Assault Among College Students.

Many colleges and universities conduct web-based campus climate surveys to understand the prevalence and nature of sexual assault among their students. When designing and fielding a web survey to measure a sensitive topic like sexual assault, methodological decisions, including the length of the field period and the use or amount of an incentive, can affect the representativeness of the respondent sample leading to biased or imprecise estimates. This study uses data from the Campus Climate Survey Validation Study (CCSVS) to assess how the interaction between field period length and survey incentive amount affects nonresponse, sample representativeness, and the precision of survey estimates.

Reducing excessive questions in adults at adult-day training centers using differential-reinforcement-of-low rates.

Differential-reinforcement-of-low rate (DRL) schedules are often used to reduce, not eliminate, behavior. We systematically replicated Austin and Bevan (2011) to determine whether the number of questions asked by two adults with intellectual disabilities working at adult-day-training centers could be reduced using a full-session DRL. The full-session DRL involved delivery of a reinforcer at the end of the day if the number of questions asked was less than a specified number during the entire session.

Gambling-related cognitive distortions predict level of function among US veterans seeking treatment for gambling disorders.

Background And Objectives: Gambling Disorder (GD) is characterized by recurrent gambling behavior that is associated with significant impairment and distress, high psychiatric comorbidities, and high functional disability. The military veteran population appears particularly susceptible to developing the disorder, but relatively little has been studied among this population. The purpose of the present study is to investigate the clinical psychopathologies and comorbidities of veterans seeking treatment for problem gambling and how problem gambling may impact functioning.

Sensitivity of Sexual Victimization Estimates to Definitional and Measurement Decisions.

Self-report surveys are subject to measurement error associated with variation in the methodology employed. The current analysis uses data from the Campus Climate Survey Validation Study (CCSVS) to examine the impact that measurement decisions have on estimates. The findings demonstrate that asking victims to provide detailed information in an effort to properly place incidents in time and classify incidents by type resulted in relatively minor decreases in estimate magnitude.

Reinforcer magnitude affects delay discounting and influences effects of d-amphetamine in rats.

Impulsive choice in humans can be altered by changing reinforcer magnitude; however, this effect has not been found in rats. Current levels of impulsive choice can also influence effects of d-amphetamine. This study used a within-subject assessment to determine if impulsive choice is sensitive to changes in reinforcer magnitude, and whether effects of d-amphetamine are related to current levels of impulsive choice.

Disclosure of sexual assault experiences among undergraduate women at historically black colleges and universities (HBCUs).

Objective: To document the sexual assault disclosure experiences of historically black college or university (HBCU) students.

Participants: A total of 3,951 female, undergraduate students at 4 HBCUs.

Methods: All women at the participating schools were recruited in November 2008 to participate in a Web-based survey including both closed- and open-ended questions.

Extra (non-contingent) food does not affect behavioral tolerance to d-amphetamine's rate-decreasing effects.

Tolerance refers to the diminished effect of a drug following its repeated administration such that a larger dose is needed to obtain the initial effect. Tolerance to a drug's effects on operant behavior is more likely to develop when initial drug administration results in a loss of reinforcement. It remains unknown how offsetting loss of reinforcement influences the development of tolerance.

Measuring Sexual Victimization: On What Fronts is the Jury Still Out and Do We Need it to Come In?

Rennison and Addington use National Crime Victimization Survey (NCVS) data to document the fact that college women experience violent victimization at a lower rate than women of the same age who do not attend college, which refutes the idea that women in college are at increased risk of being victimized. The measurement of victimization, especially sexual victimization, is, however, a topic that has be the source of much debate. Bureau of Justice Statistics is currently exploring what are the best methods for measuring sexual victimization within the NCVS, and recent methodological research, which is summarized in this article, could inform this process.

The KRAB zinc finger protein RSL1 modulates sex-biased gene expression in liver and adipose tissue to maintain metabolic homeostasis.

Krüppel-associated box zinc finger proteins (KRAB-ZFPs) are a huge family of vertebrate-specific repressors that modify gene expression in an epigenetic manner. Despite a well-defined repression mechanism, few biological roles or gene targets of KRAB-ZFP are known. Regulator of sex-limitation 1 (RSL1) is a mouse KRAB-ZFP that enforces male-predominant expression in the liver, affecting body mass and pubertal timing.

Intimate partner violence victimization among undergraduate women at Historically Black Colleges and Universities (HBCUs).

Despite the evidence that young and minority women may be particularly vulnerable to intimate partner violence (IPV), there is little research on the IPV experiences of minority undergraduate women. This study addresses this gap by estimating the prevalence of IPV and examining factors associated with experiencing IPV among undergraduate women attending Historically Black Colleges or Universities (HBCUs). Findings suggest alarmingly high victimization rates; however, factors associated with IPV among HBCU women are similar to those found in prior research with women in the general population.

The context and consequences of sexual assault among undergraduate women at Historically Black Colleges and Universities (HBCUs).

To examine the context of sexual assault and postassault actions and consequences among women attending historically Black colleges or universities (HBCUs), web-based surveys were administered in November 2008 to 3,951 undergraduate women attending four HBCUs. Data on the context in which assaults occurred were generated for women who had been sexually assaulted since entering college (n = 358). Multivariate models were run on the full sample to examine the association between sexual assault and symptoms of depression and posttraumatic stress disorder (PTSD).

The KRAB zinc finger protein RSL1 regulates sex- and tissue-specific promoter methylation and dynamic hormone-responsive chromatin configuration.

Over 400 Krüppel-associated box zinc finger proteins (KRAB-ZFPs) are encoded in mammalian genomes. While KRAB-ZFPs strongly repress transcription in vitro, little is known about their biological function or gene targets in vivo. Regulator of sex limitation 1 (Rsl1), one of the first KRAB-Zfp genes assigned a physiological role, accentuates sex-biased liver gene expression, most dramatically for mouse sex-limited protein (Slp), which provides an in vivo reporter of KRAB-ZFP function.

A within-subject analysis of d-amphetamine exposure on delay discounting in rats.

Studies concerning the relation between stimulant drug exposure and subsequent delay discounting (impulsive choice) have resulted in mixed findings that could be related to the type of stimulant drug exposure or the use of between-subject comparisons. The purpose of the present study was to examine effects of prior D-amphetamine exposure on subsequent delay discounting using a within-subject assessment. Two groups of rats were trained under a discrete-trials choice procedure until delay discounting was stable.

Preference reversals and effects of D-amphetamine on delay discounting in rats.

Impulsive choice is correlated with behavioral problems such as attention-deficit/hyperactivity disorder and substance abuse. Effects of stimulant drug administration on impulsive choice are not consistent and may depend on baseline differences in impulsive choice. A within-session delay-discounting procedure in which choice was between one food pellet delivered immediately (impulsive choice) and three food pellets delivered after increasing delays (self-controlled choice) was used to determine effects of adding and subtracting delays common to both reinforcers on impulsive choice in male Sprague-Dawley rats (n=8).

Strain differences in delay discounting between Lewis and Fischer 344 rats at baseline and following acute and chronic administration of d-amphetamine.

Stimulant drugs have been shown either to increase or decrease rates of delay discounting (impulsive choice). These mixed findings may result from genetic, neurochemical, or environmental factors. Lewis (LEW) and Fischer 344 (F344) rats have neurochemical and behavioral differences that may be relevant to delay discounting and were used to examine effects of acute and chronic administration of d-amphetamine (d-AMP) on impulsive choice using a within-session delay-discounting procedure.

The sexual assault of undergraduate women at historically Black colleges and universities (HBCUs).

Although research has shown that undergraduate women are at high risk for experiencing sexual assault, little research has been conducted with undergraduate women who are attending a historically Black college or university (HBCU). The purpose of this research is to document the prevalence of different types of sexual assault among undergraduate women at HBCUs and make comparisons to data collected from undergraduate women at non-HBCUs. Data on sexual assault victimization were collected from 3,951 undergraduate women at HBCUs using a cross-sectional, web-based survey.

Women's sexual orientations and their experiences of sexual assault before and during university.

Purpose: We sought to examine relationships between women's sexual orientations and their sexual assault experiences before and during university.

Methods: Self-reported responses on a web-based survey of 5,439 female undergraduates who participated in the Campus Sexual Assault study were analyzed to compare three groups: bisexuals, lesbians, and heterosexuals. Groups were compared in terms of the prevalence of sexual assault before and during university, and the extent to which sexual assault before university predicted sexual assault during university.

Comparing sexual assault prevalence estimates obtained with direct and indirect questioning techniques.

Concerns have been expressed about the validity of self-reported data on sexual assault, as victims might be reluctant to disclose what happened to them. In this study, using an anonymous, web-based survey, a sample of 5,446 undergraduate women were asked about their experiences with physically forced sexual assault using both direct and indirect questioning methods. The prevalence of physically forced sexual assault obtained via indirect questioning was slightly higher than, though not substantially or statistically different from, the estimate obtained via direct questioning.

The mediating effect of depressive symptoms on the relationship between traumatic childhood experiences and drug use initiation.

Stressful experiences such as childhood trauma and depressive symptoms have both been implicated in the initiation of drug use; however, longitudinal designs have not yet been used to elucidate their respective roles to better understand the causal sequence. In the present study, a sensitivity analysis was conducted using two mediation strategies to examine how this sequence may differ by various levels of statistical control, including (1) the standard mediational model in which the effect of lifetime traumatic stressors (Year 1) on the onset of drug use (Years 3 and 4) is mediated by levels of depressive symptoms (Year 2); and (2) a stronger test of causality such that the effect of lifetime traumatic stressors (Year 1) on the onset of drug use (Years 3 and 4) was mediated by changes in depressive symptoms (Year 1 to 2), measured by a residualized change score that controlled for levels in Year 1. Two types of trauma were studied in a community-based study of 489 Hispanic preadolescents (aged 10-12): (a) the number of lifetime traumatic stressors and (b) seven specific lifetime stressors.

Veterans Health Administration Transitional work experience vs. job placement in veterans with co-morbid substance use and non-psychotic psychiatric disorders.

Objective: This study seeks to compare the effectiveness of Veterans Health Administration's (VHA) transitional work experience (TWE) services and a minimal but common intervention-job placement (JP) services, for veterans with co-morbid substance and psychiatric disorders.

Methods: We conducted a random clinical trial comparing work outcomes for 89 veterans with co-morbid psychiatric and substance use disorders (SUD) who were randomly assigned to participate in VHA TWE services with those assigned to simple JP services provided by state vocational rehabilitation professionals. Participants were enrolled at the time of application to VHA TWE services and then randomly assigned to the two treatment groups and followed for 12 months.

The risk of assimilating? Alcohol use among immigrant and U.S.-born Mexican youth.

Rising rates of substance use among Hispanic youth, coupled with substantial growth of this minority group, merit grounds for concern. The process of assimilation is frequently examined in studies of Hispanic substance use and has been cited as a reason for higher rates of substance use by U.S.

A pair of mouse KRAB zinc finger proteins modulates multiple indicators of female reproduction.

Krüppel-associated box-zinc finger proteins (KRAB-ZFPs) are the largest class of transcriptional regulators in mammals, yet few have been assigned biological roles. Cloning the genes underlying the regulator of sex-limitation (rsl) phenotype, in which the normally male-specific sex-limited protein (SLP) is expressed in female mice, identified two KRAB-ZFPs, Rsl1 and Rsl2, as influencing sexually dimorphic liver gene expression. Combined absence of both repressors in rsl mice leads to increased expression in female liver of major urinary proteins (MUPs) and certain enzymes of steroid metabolism, as well as SLP.

The differential risk factors of physically forced and alcohol- or other drug-enabled sexual assault among university women.

The Campus Sexual Assault Study examined whether undergraduate women's victimization experiences prior to college and lifestyle activities during college were differentially associated with the type of sexual assault they experienced: physically forced sexual assault and incapacitated sexual assault. Self-reported data collected using a Web-based survey administered to more than 5,000 undergraduate women at two large public universities indicated that victimization experiences before college were differentially associated with the risk of experiencing these two types of sexual assault during college. Women who experienced forced sexual assault before college were at very high risk of experiencing forced sexual assault during college (odds ratio [OR] = 6.
