Unpacking The Black Box Of Survey Costs, Kristen M. Olson Jan 2020

Unpacking The Black Box Of Survey Costs, Kristen M. Olson

Department of Sociology: Faculty Publications

Survey costs are a critically important input to and constraint on the quality of data collected from surveys. Much about survey costs is unknown, leading to lack of understanding of the drivers of survey costs, the relationship between survey costs and survey errors, and difficulty in justifying the importance of survey data versus other available administrative or organic data. This commentary outlines a recently developed typology for survey costs, illustrates this typology using methodological articles that report on costs in pharmacy surveys, and provides recommendations for research on the relationship between fixed and variable costs as a major area for …


Survey Costs: Where Are We And What Is The Way Forward?, Kristen M. Olson, James Wagner, Raeda Anderson Jan 2020

Survey Costs: Where Are We And What Is The Way Forward?, Kristen M. Olson, James Wagner, Raeda Anderson

Department of Sociology: Faculty Publications

Survey costs are a major driver of survey design decisions and thought to be related to survey errors. Despite their importance, no common language exists for discussing survey costs, nor are there established criteria for identifying which cost metrics are useful for which purposes. Past efforts to study survey costs may have been hampered by the notion that more reporting is better reporting. This article starts by introducing a typology for survey cost metrics defined by the type of cost (estimated, observed in records, and actually incurred), currency versus non-currency measures, and level of aggregation (total, by components, per unit, …


A Comparison Of Frequency Of Alcohol And Marijuana Use Using Short Message Service Surveying And Survey Questionnaires Among Homeless Youth, Kimberly A. Tyler, Kristen M. Olson Jan 2020

A Comparison Of Frequency Of Alcohol And Marijuana Use Using Short Message Service Surveying And Survey Questionnaires Among Homeless Youth, Kimberly A. Tyler, Kristen M. Olson

Department of Sociology: Faculty Publications

Background: There are several benefits to using short message service surveying (SMS) to gather data on substance use from homeless youth, including capturing data “in the moment” and verifying the timing of one behavior relative to another. Though SMS is a valuable data collection tool with highly mobile populations that otherwise are difficult to longitudinally sample, the reliability of SMS compared with surveys is largely unknown with homeless youth. Examining the reliability of SMS is important because these data can provide a more nuanced understanding of the relationships between various risk behaviors, which may lead to better intervention strategies …


How Do Interviewers And Respondents Navigate Sexual Identity Questions In A Cati Survey?, Jerry Timbrook, Jolene Smyth, Kristen M. Olson Jan 2020

How Do Interviewers And Respondents Navigate Sexual Identity Questions In A Cati Survey?, Jerry Timbrook, Jolene Smyth, Kristen M. Olson

Department of Sociology: Faculty Publications

Survey-based research has demonstrated that sexual minority individuals experience unique outcomes in areas such as physical and mental health (Boehmer et al. 2007; Hatzenbuehler 2014, 2017), crime (Herek 2009), public education (Kosciw et al. 2015), same-sex romantic relationships and family (Powell and Downey 1997; Umberson et al. 2015), and economics (Black et al. 2007). Having a reliable and valid measure of sexual identity (i.e., the way in which an individual self-describes their sexual orientation) (Gagnon and Simon 1973) is essential for conducting research on sexual minorities. Indeed, many national surveys such as the General Social Survey, the National Health Interview …


Male/Female Is Not Enough: Adding Measures Of Masculinity And Femininity To General Population Surveys, Jolene Smyth, Kristen Olson Jan 2020

Male/Female Is Not Enough: Adding Measures Of Masculinity And Femininity To General Population Surveys, Jolene Smyth, Kristen Olson

Department of Sociology: Faculty Publications

Survey research and sociological theory each provide insights into how and why people and groups act, think, and feel. Sociological theories identify what concepts are important for understanding and representing the social world. That is, sociological theories inform what to measure in surveys, and, to a certain extent, how to measure it. Survey research permits sociologists to carefully specify what is to be measured vis a vis sociological theory, setting surveys apart as a social research tool. It is this level of specification of concepts and measures that allow surveys to provide continued value at a time when “big data” …


Diverse Sources Of Social Support And Cognitive Functioning By Race, Ethnicity, And Nativity, G. Robin Gauthier, Marc A. Garcia, Catherine García Jan 2020

Diverse Sources Of Social Support And Cognitive Functioning By Race, Ethnicity, And Nativity, G. Robin Gauthier, Marc A. Garcia, Catherine García

Department of Sociology: Faculty Publications

This study examines the relationship between social support profiles and cognitive functioning by race, ethnicity and nativity in older adults using cross-sectional data drawn from the Health and Retirement Study (2010 and 2012). We employed a hierarchical clustering routine to generate nine support profiles that differentiated three sources of support: children, wider family relationships and friendships. Cognitive functioning was measured as the score on the Telephone Interview for Cognitive Status (TICS-m), a 27 point scale of cognitive function. Our approach explicitly acknowledges the ambivalence and multidimensionality of close relationships and the resources embedded within them. Descriptive analyses revealed significant differences …


Competing Forces Of Withdrawal And Disease Avoidance In The Risk Networks Of People Who Inject Drugs, Elspeth Ready, Patrick Habecker, Roberto Abadie, Bilal Khan, Kirk Dombrowski Jan 2020

Competing Forces Of Withdrawal And Disease Avoidance In The Risk Networks Of People Who Inject Drugs, Elspeth Ready, Patrick Habecker, Roberto Abadie, Bilal Khan, Kirk Dombrowski

Department of Sociology: Faculty Publications

We analyze a network of needle-sharing ties among 117 people who inject drugs (PWID) in rural Puerto Rico, using exponential random graph modeling to examine whether network members engage in partner restriction to lower their risk of contracting HIV or hepatitis C (HCV), or in informed altruism to prevent others from contracting these infections. Although sharing of used syringes is a significant risk factor for transmission of these diseases among PWID, we find limited evidence for partner restriction or informed altruism in the network of reported needle-sharing ties. We find however that sharing of needles is strongly reciprocal, and individuals …


Contextualizing The Covid-19 Era In Puerto Rico: Compounding Disasters And Parallel Pandemics, Catherine Garcia, Fernando I. Rivera, Marc A. Garcia, Giovani Burgos, María P. Aranda Jan 2020

Contextualizing The Covid-19 Era In Puerto Rico: Compounding Disasters And Parallel Pandemics, Catherine Garcia, Fernando I. Rivera, Marc A. Garcia, Giovani Burgos, María P. Aranda

Department of Sociology: Faculty Publications

Objectives: The COVID-19 outbreak has worsened the ongoing economic crisis in Puerto Rico by creating "parallel pandemics" that exacerbate socioeconomic and health inequalities experienced by its most vulnerable residents. Unfortunately, conditions on the island have been largely overlooked by national media outlets and the mainland U.S. population. Thus, this research report aims to draw attention to the disparate burden multiple and compounding disasters have on older island-dwelling Puerto Rican adults’ health and well-being.

Methods: We characterize the lived experiences of the older population in Puerto Rico by incorporating data from numerous sources and contextualizing the effects of compounding disasters, the …


“Caballo”: Risk Environments, Drug Sharing And The Emergence Of A Hepatitis C Virus Epidemic Among People Who Inject Drugs In Puerto Rico, Roberto Abadie, K. Dombrowski Jan 2020

“Caballo”: Risk Environments, Drug Sharing And The Emergence Of A Hepatitis C Virus Epidemic Among People Who Inject Drugs In Puerto Rico, Roberto Abadie, K. Dombrowski

Department of Sociology: Faculty Publications

Background: Sharing drug injection equipment has been associated with the transmission of HCV among PWID through blood contained in the cooker and cotton used to prepare and divide up the drug solution. While epidemiologists often subsume this practice under the sharing of “ancillary equipment,” more attention should be paid to the fact that indirect sharing takes place within the process of joint drug acquisition and preparation.

Methods: We employed an ethnographic approach observing active PWID (N = 33) in four rural towns in Puerto Rico in order to document drug sharing arrangements involved in “caballo”, as this practice is locally …


Soldiers To Scientists: Military Service, Gender, And Stem Degree Earning, Christina Steidl, Regina E. Werum, Sela R. Harcey, Jacob Absalon, Alice Millermacphee Jan 2020

Soldiers To Scientists: Military Service, Gender, And Stem Degree Earning, Christina Steidl, Regina E. Werum, Sela R. Harcey, Jacob Absalon, Alice Millermacphee

Department of Sociology: Faculty Publications

The authors use 2014–2018 data from the American Community Survey to answer two questions: To what extent is military service associated with higher rates of earning a bachelor’s degree in a science, technology, engineering, and mathematics (STEM) field (vs. a non-STEM field)? To what extent is this relationship gendered? The findings suggest that military service is associated with higher odds of completing a STEM degree and that this association is particularly strong for female veterans. Comparison across multiple STEM definitions suggests that military service does not simply channel women into traditionally female-dominated STEM fields. Instead, the findings show the biggest …


The Stress Mechanisms Of Adolescent Physical, Mental, And Behavioral Health, Lisa Kort-Butler Jan 2020

The Stress Mechanisms Of Adolescent Physical, Mental, And Behavioral Health, Lisa Kort-Butler

Department of Sociology: Faculty Publications

Although the mechanisms are complex, stress is a risk factor for compromised physical, mental, and behavioral health in adolescence. The stress paradigm posits a system of relationships among social structures, stressors, personal and social resources, and health outcomes, offering a framework for understanding how adolescents’ life problems and the means to cope with them affect well-being. This chapter reviews the theoretical underpinnings of the stress paradigm, drawing on the stress process model and general strain theory. The chapter briefly reviews the biological underpinnings of stress and the role of brain development. Then, the chapter focuses on the social aspects of …


The Past, Present, And Future Of Research On Interviewer Effects, Kristen M. Olson, Jolene Smyth, Jennifer Dykema, Allyson L. Holbrook, Frauke Kreuter, Brady T. West Jan 2020

The Past, Present, And Future Of Research On Interviewer Effects, Kristen M. Olson, Jolene Smyth, Jennifer Dykema, Allyson L. Holbrook, Frauke Kreuter, Brady T. West

Department of Sociology: Faculty Publications

Interviewer-administered surveys are a primary method of collecting information from populations across the United States and the world. Various types of interviewer-administered surveys exist, including large-scale government surveys that monitor populations (e.g., the Current Population Survey), surveys used by the academic community to understand what people think and do (e.g., the General Social Survey), and surveys designed to gauge public opinion at a particular time point (e.g., the Gallup Daily Tracking Poll). Interviewers participate in these data collection efforts in a multitude of ways, including creating lists of housing units for sampling, persuading sampled units to participate, and administering survey …


What Do Interviewers Learn?: Changes In Interview Length And Interviewer Behaviors Over The Field Period, Kristen M. Olson, Jolene Smyth Jan 2020

What Do Interviewers Learn?: Changes In Interview Length And Interviewer Behaviors Over The Field Period, Kristen M. Olson, Jolene Smyth

Department of Sociology: Faculty Publications

Interviewers are important actors in telephone surveys. By setting the pace for an interview, interviewers communicate the amount of time and cognitive effort respondents should put into their task. It is well-established that interviewers vary widely in the time they spend administering a survey, and that this time changes over the course of the data collection period as interviewers gain experience (Bohme and Stohr 2014; Kirchner and Olson 2017; Loosveldt and Beullens 2013a, 2013b; Olson and Bilgen 2011; Olson and Peytchev 2007). In particular, interviewers get faster as they gain experience over the field period of a survey.

The within-survey …


Paid Paternity Leave-Taking In The United States, Richard J. Petts, Chris Knoester, Qi Li Jan 2020

Paid Paternity Leave-Taking In The United States, Richard J. Petts, Chris Knoester, Qi Li

Department of Sociology: Faculty Publications

Surprisingly few studies have focused on paternity leave-taking in the United States. This study utilizes data from three national datasets to provide a comprehensive examination of the attitudes, practices, and predictors of paid paternity leave-taking in the US. Specifically, this study focuses on (a) describing attitudes toward fathers receiving a share of paid parental leave, (b) describing rates and lengths of paid paternity leave-taking, and (c) analyzing the extent to which economic capital, cultural capital, social capital, and father identities predict paternity leave-taking practices. The results indicate that most people support fathers receiving a share of paid parental leave in …


Coproid Predicts The Source Of Coprolites And Paleofeces Using Microbiome Composition And Host Dna Content, Maxime Borry, Bryan Cordova, Angela Perri, Marsha Wibowo, Tanvi Prasad Honap, Jada Ko, Kate Britton, Linus Girdland-Flink, Robert C.

Karl Reinhard Publications

Shotgun metagenomics applied to archaeological feces (paleofeces) can bring new insights into the composition and functions of human and animal gut microbiota from the past. However, paleofeces often undergo physical distortions in archaeological sediments, making their source species difficult to identify on the basis of fecal morphology or microscopic features alone. Here we present a reproducible and scalable pipeline using both host and microbial DNA to infer the host source of fecal material. We apply this pipeline to newly sequenced archaeological specimens and show that we are able to distinguish morphologically similar human and canine paleofeces, as well as non-fecal …


Diet Analysis Reveals Pre-Historic Meals Among The Loma San Gabriel At La Cueva De Los Muertos Chiquitos, Rio Zape, Mexico (600–800 Ce), Elisa Pucu, Julia Russ, Karl Reinhard Jan 2020

Diet Analysis Reveals Pre-Historic Meals Among The Loma San Gabriel At La Cueva De Los Muertos Chiquitos, Rio Zape, Mexico (600–800 Ce), Elisa Pucu, Julia Russ, Karl Reinhard

Karl Reinhard Publications

Coprolites have been a source of study for archeologists due to several reasons: they not only provide information on the life and nutritional habits of ancient individuals but also on their health. In this paper, we processed 10 coprolites collected at La Cueva de Los Muertos Chiquitos (600–800 CE), Rio Zape, Mexico, with acetolysis solution for pollen analysis. The number of pollen grains/gram of each coprolite sample was quantified along with the macroscopic remains of these samples. The main food item ingested by the population was maize, followed by Agave. Squash blossoms were also part of their food source …


Pinworm Research In The Southwest Usa: Five Decades Of Methodological And Theoretical Development And The Epidemiological Approach, Morgana Camacho, Karl Reinhard Jan 2020

Pinworm Research In The Southwest Usa: Five Decades Of Methodological And Theoretical Development And The Epidemiological Approach, Morgana Camacho, Karl Reinhard

Karl Reinhard Publications

Pinworms infected Ancestral Pueblo populations since early periods of occupation on the Colorado Plateau. The high prevalence of pinworm found in these populations was correlated with the habitation style developments through time. However, in previous studies, Turkey Pen Cave, an early occupation site, and Salmon Ruins, a late occupation site, exhibited prevalences that were anomalously low, suggesting that these sites were outliers. Alternatively, it is possible that the previous quantification method was not successful in detecting the real prevalence and eggs per gram, which led to inexact interpretations. The aims of this study were to verify if previous pinworm prevalences …


Serotonin 5-Ht2a And 5-Ht2c Receptors Regulate Rat Maternal Behavior Through Distinct Behavioral And Neural Mechanisms, Jun Gao, Lina Nie, Yu Li, Ming Li Jan 2020

Serotonin 5-Ht2a And 5-Ht2c Receptors Regulate Rat Maternal Behavior Through Distinct Behavioral And Neural Mechanisms, Jun Gao, Lina Nie, Yu Li, Ming Li

Department of Psychology: Faculty Publications

Serotonin 5-HT2A and 5-HT2C receptors play important yet distinctive roles in the regulation of rat maternal behavior. The present study investigated their neural substrates and explored the possible behavioral mechanisms (i.e., behavioral organization or maternal motivation). Sprague-Dawley postpartum females were microinjected with either a selective 5-HT2A agonist (TCB-2, 0.4 or 4.0 μg/side) or a 5-HT2C agonist (MK212, 2.5 or 5.0 μg/side) into the medial prefrontal cortex (mPFC) or ventral tegmental area (VTA). Ten and 60 min later, their maternal activities were observed in the home cage; and their motivational responses towards pups were examined in a …

The Connectomes Related to Human Diseases (CRHD) initiative was developed with the Human Connectome Project (HCP) to provide high-resolution, open-access, multi-modal MRI data to better understand the neural correlates of human disease. Here, we present an introduction to a CRHD project, the Boston Adolescent Neuroimaging of Depression and Anxiety (BANDA) study, which is collecting multimodal neuroimaging, clinical, and neuropsychological data from 225 adolescents (ages 14–17), 150 of whom are expected to have a diagnosis of depression and/or anxiety. Our transdiagnostic recruitment approach samples the full spectrum of depressed/anxious symptoms and their comorbidity, consistent with NIMH Research Domain Criteria (RDoC). We …


Identifying And Addressing Barriers To Treatment For Child Sexual Abuse Survivors And Their Non-Offending Caregivers, Kate Theimer, Akemi E. Mii, Emily Sonnen, Kelsey Mccoy, Katie Meidlinger, Brittany Biles, T. Zachary Huit, Mary F. Flood, David J. Hansen Jan 2020

Identifying And Addressing Barriers To Treatment For Child Sexual Abuse Survivors And Their Non-Offending Caregivers, Kate Theimer, Akemi E. Mii, Emily Sonnen, Kelsey Mccoy, Katie Meidlinger, Brittany Biles, T. Zachary Huit, Mary F. Flood, David J. Hansen

Department of Psychology: Faculty Publications

Mental health treatment is a critical part of an effective and compassionate response to the disclosure of child sexual abuse (CSA). Given the vast negative consequences for children and families following CSA, engagement in treatment can benefit youth and their non-offending caregivers. Yet, these families face unique barriers to treatment initiation, adherence, and effectiveness. The identification of these barriers allows clinicians, researchers, and policy makers to increase treatment utilization, engagement, and value. The current review and its recommendations derive from the existing literature combined with knowledge gained from a clinical research team with more than 20 years of experience offering …


Attributions Of Blame In A Hypothetical Child Sexual Abuse Case: Roles Of Behavior Problems And Frequency Of Abuse, Kate Theimer, David J. Hansen Jan 2020

Attributions Of Blame In A Hypothetical Child Sexual Abuse Case: Roles Of Behavior Problems And Frequency Of Abuse, Kate Theimer, David J. Hansen

Department of Psychology: Faculty Publications

Youth who are blamed for their sexual abuse may experience increased negative outcomes, such as amplified self-blame. Similarly, blaming nonoffending parents can impede their ability to support their child following disclosure. Understanding the factors that influence how people perceive victim, caregiver, and perpetrator responsibility is imperative for the protection and treatment of families who have experienced sexual abuse. Little research has explored victim and abuse characteristics that influence the perception of sexual abuse. As such, the purpose of this study was to examine the roles of behavior problems and frequency of abuse in the attribution of blame in a hypothetical …

Smoking remains a significant health and economic concern in the United States. Furthermore, the emerging pattern of nicotine intake between sexes further adds a layer of complexity. Nicotine is a potent psychostimulant with a high addiction liability that can significantly alter brain function. However, the neurobiological mechanisms underlying nicotine’s impact on brain function and behavior remain unclear. Elucidation of these mechanisms is of high clinical importance and may lead to improved therapeutics for smoking cessation. To fill in this critical knowledge gap, our current study focused on identifying sex-specific brain-derived extracellular vesicles (BDEV) signatures in male and female rats post …


Definitions Of Water Quality: A Survey Of Lake-Users Of Water Quality-Compromised Lakes, Ashley Votruba, Jessica R. Corman Jan 2020

Definitions Of Water Quality: A Survey Of Lake-Users Of Water Quality-Compromised Lakes, Ashley Votruba, Jessica R. Corman

Department of Psychology: Faculty Publications

Understanding and defining water quality is an important precursor for influencing pro-environmental behavior and accurately assessing potential outcomes of human–lake interactions. This study surveyed 82 lake-users in Nebraska regarding their definitions of water quality and the importance of various water quality features to determine if lake-users’ definitions align with complex and multi-faceted governmental and scientific definitions. Survey sites included two recreational reservoirs (e.g., boating and fishing), Holmes Lake (urban watershed) and Branched Oak Lake (agricultural watershed). The biological and chemical parameters are similar between the lakes and both lakes were listed as “impaired” on the Section 303(d) (United States Environmental …


Correspondence Between Cytomegalovirus Immunoglobulin-G Levels Measured In Saliva And Serum, Jenna L. Riis, Hedyeh Ahmadi, Olivia Silke, Steve W. Granger, Crystal I. Bryce, Douglas A. Granger Jan 2020

Correspondence Between Cytomegalovirus Immunoglobulin-G Levels Measured In Saliva And Serum, Jenna L. Riis, Hedyeh Ahmadi, Olivia Silke, Steve W. Granger, Crystal I. Bryce, Douglas A. Granger

Department of Psychology: Faculty Publications

Human cytomegalovirus (HCMV) infects more than 80% of the global population. While mostly asymptomatic, HCMV infection can be serious among the immunocompromised, and it is implicated in chronic disease pathophysiology in adulthood. Large-scale minimally invasive HCMV screening could advance research and public health efforts to monitor infection prevalence and prevent or mitigate downstream risks associated with infection. We examine the utility of measuring HCMV immunoglobulin-G (IgG) levels in saliva as an index of serum levels. Matched serum and saliva samples from healthy adults (N = 98; 44% female; 51% white) were assayed for HCMV IgG, total salivary protein, and salivary …


Moving Beyond Executive Functions: Challenge Preference As A Predictor Of Academic Achievement In Elementary School, Michael J. Sulik, Jenna E. Finch, Jelena Obradović Jan 2020

Moving Beyond Executive Functions: Challenge Preference As A Predictor Of Academic Achievement In Elementary School, Michael J. Sulik, Jenna E. Finch, Jelena Obradović

Department of Psychology: Faculty Publications

Intrinsic motivation and executive functions (EFs) have been independently studied as predictors of academic achievement in elementary school. The goal of this investigation was to understand how students’ challenge preference (CP), an aspect of intrinsic motivation, is related to academic achievement while accounting for EFs as a confounding variable. Using data from a longitudinal study of 569 third-, fourth-, and fifth-graders (50% female), we tested students’ self-reported CP as a predictor of mathematics and English language arts (ELA) achievement in multilevel models that controlled for school fixed effects and student demographic characteristics. CP was positively associated with mathematics and ELA …


Maternal Depression And Breastfeeding In Home Visitation, Francesca A. Scheiber, Lisa S. Segre, Michael W. O'Hara, Darby Taylor, Rebecca L. Brock Jan 2020

Maternal Depression And Breastfeeding In Home Visitation, Francesca A. Scheiber, Lisa S. Segre, Michael W. O'Hara, Darby Taylor, Rebecca L. Brock

Department of Psychology: Faculty Publications

Background: Home visitation is a popular mechanism for supporting parents and their young children. Breastfeeding is often promoted by home visitors due to its health benefits. However, maternal depression may interfere with breastfeeding. Thus, home visitors may be attempting to encourage health-promoting behaviors like breastfeeding, but maternal depression may interfere with engagement in those behaviors. Method: The data for this study were provided by the Des Moines Healthy Start and the Empowerment Family Support Project (DMHSP). We analyzed the relation between depression and breastfeeding for 364 women. Results: First, rates of elevated depression scores in this sample of women (8.7%–21.4% …


Social Responsiveness And Objectification: The Moderating Roles Of Serotonin Transporter And Serotonin Receptor 2a Genotypes In An Objectification Theory Model Of Disordered Eating, Grace A. Sullivan, Sarah J. Gervais, Rebecca L. Brock, Scott F. Stoltenberg Jan 2020

Social Responsiveness And Objectification: The Moderating Roles Of Serotonin Transporter And Serotonin Receptor 2a Genotypes In An Objectification Theory Model Of Disordered Eating, Grace A. Sullivan, Sarah J. Gervais, Rebecca L. Brock, Scott F. Stoltenberg

Department of Psychology: Faculty Publications

Feminist scholars have called for gender researchers to consider gene-environment interactions for gender-imbalanced disorders (Salk and Hyde Psychology of Women Quarterly, 36, 395–411, 2012). Responding to these calls, the present study integrates objectification theory (Fredrickson and Roberts Psychology of Women Quarterly, 21, 173–206, 1997) and genetic research. In the tested model, objectification experiences are associated with disordered eating through body surveillance and body shame, and serotonin transporter (SLC6A4) genotypes (5-HTTLPR and rs25531), serotonin 2A receptor SNP genotypes (HTR2A rs6311), and the epistatic interaction between those genotypes function as moderators. U.S. undergraduate women (n = 526) …


“A Victim/Survivor Needs Agency”: Sexual Assault Survivors’ Perceptions Of University Mandatory Reporting Policies, Kathryn J. Holland, Allison E. Cipriano, T. Zachary Huit Jan 2020

“A Victim/Survivor Needs Agency”: Sexual Assault Survivors’ Perceptions Of University Mandatory Reporting Policies, Kathryn J. Holland, Allison E. Cipriano, T. Zachary Huit

Department of Psychology: Faculty Publications

In institutions of higher education, mandatory reporting policies require certain employees to report students’ sexual assault disclosures to university officials, even if the student does not want to report. It is commonly assumed that these policies will benefit survivors, but there is a paucity of research to substantiate this assumption. The current study examined college sexual assault survivors’ perceptions of mandatory reporting policies, including three specific policy approaches (Universal, Selective, Student-Directed). Interviews were conducted with 40 college sexual assault survivors and thematic analysis was used to analyze these data. Results found that the mandatory reporting policy approaches that survivors prefer, …


“You Can Catch More Flies With Honey Than Vinegar”: Objectification Valence Interacts With Women’S Enjoyment Of Sexualization To Influence Social Perceptions, Abigail R. Riemer, Jill Allen, Marco Gullickson, Sarah Gervais Jan 2020

“You Can Catch More Flies With Honey Than Vinegar”: Objectification Valence Interacts With Women’S Enjoyment Of Sexualization To Influence Social Perceptions, Abigail R. Riemer, Jill Allen, Marco Gullickson, Sarah Gervais

Department of Psychology: Faculty Publications

Although objectification is a common experience for women (Fredrickson & Roberts, 1997), little is understood about how women perceive sources of objectifying commentary and behaviors. The current work provides a novel integration of objectification and consistency theories to understand how valence of sexual objectification and women’s feelings about sexual attention interact to predict perceptions of objectifying sources. In two online vignette studies with 121 and 110 U.S. women recruited through MTurk, female participants were asked to recall an experience of complimentary or critical objectification and report perceptions of source warmth, approach behavioral intentions, perceived overlap between the self and the …


Reproducibility And Registration In Sexuality Research, Tierney K. Lorenz Jan 2020

Reproducibility And Registration In Sexuality Research, Tierney K. Lorenz

Department of Psychology: Faculty Publications

Most readers of the Archives of Sexual Behavior will, by now, be familiar with an upsurge of interest in best practices for reproducibility and replicability across modern scientific disciplines (Ioannidis, 2005; National Academies of Sciences Engineering and Medicine, 2019; Simmons, Nelson, & Simonsohn, 2011). Concerns about the basic validity of findings that cannot be replicated—and the widespread practices and incentive systems that lead to unverifiable results—are particularly important for social and behavioral scientists, whose fields of study are relatively younger and whose work is often interpreted as more subjective than other sciences (Lilienfeld, 2012).

As sexuality research continues to mature …
