Prospective Associations Of Homocysteine, Executive Function, And Depressive Symptoms, Peter J. Dearborn Dec 2017

Prospective Associations Of Homocysteine, Executive Function, And Depressive Symptoms, Peter J. Dearborn

Electronic Theses and Dissertations

Associations of cardiovascular risk factors, cognitive performance, and depressive symptoms have been well established. However, the directionality of these associations as well as the specificity of these associations with respect to executive function are less clear. Additionally few studies have determined whether genetic risk factors, such as apolipoprotein-E4 (APOE-E4) genotype, and age moderate the associations of cardiovascular risk factors such as homocysteine with changes in depressive symptoms and how these associations may be mediated by cognitive performance. The primary aim of this study was to analyze the bidirectional associations of a full range of cognitive domains and symptoms of depression …

Development And Validation Of The Bisexual Microaggressions Scale, Emma G. Fredrick Aug 2017

Development And Validation Of The Bisexual Microaggressions Scale, Emma G. Fredrick

Electronic Theses and Dissertations

Sexual minorities face stigmatizing experiences which can lead to disparities in physical and mental health, as well as social and economic resources. Additionally, research suggests that microaggressions, or small actions and comments that speak to a person’s prejudices, act as stigmatizing experiences and contribute to negative outcomes for the stigmatized. However, most studies of sexual minority health do not explore bisexual experiences uniquely, despite evidence that bisexuals have unique experiences of stigma and microaggressions. Those studies that do explore bisexual experiences find worse outcomes for bisexuals than their lesbian or gay counterparts. Thus, the current study developed a quantitative scale …

Mixture Modelling Of The Hexaco Personality Inventory, Carolina Patryluk Jul 2017

Mixture Modelling Of The Hexaco Personality Inventory, Carolina Patryluk

Electronic Thesis and Dissertation Repository

Mixture models are used for identifying profiles or combinations of profiles and dimensions that explain observed variables. Given that these techniques can be misapplied (Lubke & Miller, 2014), much research is needed to understand their properties when applied to various data sets. The current study tests and compares the fit of mixture models to factor analytic models of personality trait facets based on the HEXACO Personality Inventory-Revised (Ashton & Lee, 2009a). This study also examines the relative amounts of variance in the facet variables that can be explained by underlying dimensions, latent profiles, and other sources. Ashton and Lee (2009b) …

Examining The Durability Of Peers For Adolescents With Asd: Maintenance Of Neurological And Behavioral Effects, Bridget Kathleen Dolan Jul 2017

Examining The Durability Of Peers For Adolescents With Asd: Maintenance Of Neurological And Behavioral Effects, Bridget Kathleen Dolan

Dissertations (1934 -)

To date, there are no known published studies that have assessed the maintenance of treatment effects in the context of neurological changes and their relationship to behavioral outcomes following a social skills intervention for adolescents with Autism Spectrum Disorder (ASD). The few studies that have incorporated long-term assessment into their design have focused exclusively on sustained behavioral responses to treatment. Individuals with ASD across the lifespan exhibit aberrant neural activity, which is thought to underlie social skill deficits noted in persons on the spectrum. Thus, this study sought to examine the impact of a social skills intervention, the Program for …

Mapping Alternative Masculinities: Development, Validation, And Latent Profile Analysis Of A New Masculinity Measure, Jessica K. Padgett Jun 2017

Mapping Alternative Masculinities: Development, Validation, And Latent Profile Analysis Of A New Masculinity Measure, Jessica K. Padgett

Electronic Thesis and Dissertation Repository

Prominent measures of masculinity focus on traditional masculine norms, such as high aggression, low emotional expression, and heteronormativity. However, recent qualitative research has indicated that a variety of men embrace alternative forms of masculinity that include unique characteristics not represented by traditional norms. I developed the Alternative Masculinity Measure (ALT-M) to address this gap. The ALT-M was designed to measure individual differences on constructs derived from a modern, socially progressive representation of masculinity. Concepts, scales, and items were developed primarily from readings of qualitative research on alternative masculinities. Nine dimensions with 14 items each was sent to 15 experts for …

Radio Dispatch Cognitive Abilities And Working Memory, David A. Buitron Jun 2017

Radio Dispatch Cognitive Abilities And Working Memory, David A. Buitron

Electronic Theses, Projects, and Dissertations

Public safety radio dispatchers incontrovertibly have to manage multiple tasks at any given time, from relaying lifesaving information to field units, to simultaneously overseeing several monitors and keeping up with the radio transmissions in a timely manner. Interestingly, however, the underlying cognitive abilities necessitated for performing such tasks have not been thoroughly investigated. To begin understanding the cognitive faculties that underlie dispatching tasks, we gauged cognitive ability measures relevant to dispatcher duties and introduced Working Memory Capacity (WMC) as underlying the differentiation on performance. The four general dispatcher cognitive factors identified by Peace Officer Standards and Training (POST) literature, were …

Retrospective Versus Prospective Measurement Of Examinee Motivation In Low-Stakes Testing Contexts: A Moderated Mediation Model, Aaron J. Myers May 2017

Retrospective Versus Prospective Measurement Of Examinee Motivation In Low-Stakes Testing Contexts: A Moderated Mediation Model, Aaron J. Myers

Masters Theses, 2010-2019

Expectancy-value theory applied to examinee motivation suggests examinees’ perceived value of a test indirectly affects test performance via examinee effort. This empirically supported indirect effect, however, is often modeled using importance and effort scores measured after test completion, which does not align with their theoretically specified temporal order. Retrospectively measured importance and effort scores may be influenced by examinees’ test performance, impacting the estimate of the indirect effect. To investigate the effect of timing of measurement, first-year college students were randomly assigned to one of three conditions where (1) importance and effort were measured retrospectively; (2) importance was measured prospectively; …

Student Learning Gains In Higher Education: A Longitudinal Analysis With Faculty Discussion, Catherine E. Mathers May 2017

Student Learning Gains In Higher Education: A Longitudinal Analysis With Faculty Discussion, Catherine E. Mathers

Masters Theses, 2010-2019

Student learning is the primary desired outcome of a college education. To understand how educational programming and curricula affect students, colleges and universities must collect evidence of student learning gain. In this study, a longitudinal design was employed to investigate how a math and science general education curriculum impacted college students’ quantitative and scientific reasoning. Quantitative and scientific reasoning gain scores were computed and predicted from personal (i.e., prior knowledge, gender) and curriculum (i.e., number of completed courses in the domain) characteristics to uncover what factors relate to learning gain. Collapsing across personal and curriculum variables, gain scores were moderate …

Examining The Type I Error And Power Of 18 Common Post-Hoc Comparison Tests, Derek Sauder May 2017

Examining The Type I Error And Power Of 18 Common Post-Hoc Comparison Tests, Derek Sauder

Masters Theses, 2010-2019

Researchers utilizing either experimental or quasi-experimental research often want to compare group means. However, with more than two groups, comparing group means may result in an inflated Type I error rate, the probability of wrongly rejecting a null hypothesis. Researchers often employ analysis of variance (ANOVA) methodology to compare more than two group means. Post-hoc comparison procedures (PCPs) are utilized to indicate which group means differ following a significant ANOVA. SPSS provides 18 options for PCPs. The purpose of this study was to determine which PCP provides the best power while maintaining Type I error control when assumptions of ANOVA …

Using Multiple Imputation To Mitigate The Effects Of Low Examinee Motivation On Estimates Of Student Learning, Kelly J. Foelber May 2017

Using Multiple Imputation To Mitigate The Effects Of Low Examinee Motivation On Estimates Of Student Learning, Kelly J. Foelber

Dissertations, 2014-2019

In higher education, we often collect data in order to make inferences about student learning, and ultimately, in order to make evidence-based changes to try to improve student learning. The validity of the inferences we make, however, depends on the quality of the data we collect. Low examinee motivation compromises these inferences; research suggests that low examinee motivation can lead to inaccurate estimates of examinees’ ability (e.g., Wise & DeMars, 2005). To obtain data that better represent what students know, think, and can do, practitioners must consider, and attempt to negate the effects of, low examinee motivation. The primary purpose …

You Only Live Up To The Standards You Set: An Evaluation Of Different Approaches To Standard Setting, Scott N. Strickman May 2017

You Only Live Up To The Standards You Set: An Evaluation Of Different Approaches To Standard Setting, Scott N. Strickman

Dissertations, 2014-2019

Interpretation of performance in reference to a standard can provide nuanced, finely-tuned information regarding examinee abilities beyond that of just a total score. However, there is a multitude of ways to set performance standards yet little guidance regarding which method operates best and under what circumstances. Traditional methods are the most common approach adopted in practice and heavily involve subject matter experts (SMEs). Two other approaches have been suggested in the literature as alternative ways to set performance standards, although they have yet to be implemented in practice. Data-driven approaches do not involve SMEs but rather rely solely upon statistical …

The Effect Of Stigma On Intimate Partner Violence Reporting Among Men Who Have Sex With Men, Wesley Eugene Harris May 2017

The Effect Of Stigma On Intimate Partner Violence Reporting Among Men Who Have Sex With Men, Wesley Eugene Harris

Undergraduate Honors Theses

This study examined the relation between stigma and reporting of intimate partner violence (IPV) in a sample of men who have sex with men (MSM). It was hypothesized that enacted stigma would result in lower reporting of IPV and that the type of IPV would moderate the relationship between enacted stigma and reporting. Using an online survey, we measured IPV (physical, psychological, and sexual violence) and stigma (perceived, enacted, and internalized). Participants (N = 46) were asked if they had ever experienced any of those forms of violence, as well as if they had ever reported the violence through an …

A Statistical Examination Of Impaired Performances Across Concussion Screening Instruments, Kathryn Ann Ritchie Apr 2017

A Statistical Examination Of Impaired Performances Across Concussion Screening Instruments, Kathryn Ann Ritchie

Master's Theses (2009 -)

It is well documented that healthy individuals routinely obtain impaired scores on neuropsychological tests, which confounds the differential diagnosis process. Relatively little is known regarding the rates at which healthy individuals obtain impaired scores on measures that are used to detect cognitive symptoms associated with sports related concussion (SRC). The current study generated expected rates of impaired performance on the Standardized Assessment of Concussion (SAC), the Automated Neuropsychological Assessment Metrics Sports Battery (ANAM), Immediate Post-Concussion and Cognitive Testing (ImPACT), and Axon Sports (Axon) neurocognitive measures by conducting Monte Carlo analyses using data obtained from a large normative sample of amateur …

Predicting Modification And Revocation Of Insanity Acquittees On Conditional Release Using The Short-Term Assessment Of Risk And Treatability, Heidi Oliver Feb 2017

Predicting Modification And Revocation Of Insanity Acquittees On Conditional Release Using The Short-Term Assessment Of Risk And Treatability, Heidi Oliver

Doctor of Psychology (PsyD)

Violence risk assessment has evolved significantly over the past 50 years. The newest generation of risk assessment tools is intended not only to assess risk but also to inform treatment. The Short-Term Assessment of Risk and Treatability, i.e., the START, is an example of a 4thgeneration tool that identifies risk and protective factors, highlighting the dynamic variables that may decrease risk. As treatment for mentally ill offenders shifts from inpatient hospital environments to community-based treatment settings, a focus on dynamic risk factors is crucial for maintaining safety for patients and the community. This study aimed to identify the predictive validity …

Comparisons Of Artifact Correction Procedures For Meta-Analysis: An Empirical Examination On Correcting Reliabilities, Lei Zhao Jan 2017

Comparisons Of Artifact Correction Procedures For Meta-Analysis: An Empirical Examination On Correcting Reliabilities, Lei Zhao

Dissertations

This study reviewed some challenges and issues in artifact correction meta-analysis, particularly around using reliability estimates to correct for measurement error. Two individual correction procedures—the Hunter-Schmidt procedure and the procedure developed by Raju, Burke, Normand, and Langlois (the RBNL procedure)—are addressed in this research. The purpose of this study is to use real-world data to examine the differences between meta-analytic estimations produced by the two artifact correction procedures and those by the traditional bare-bones meta-analysis procedures, under the condition of inter-dependent reliabilities. The impact of this inter-correlation on meta-analysis results needs investigation when artifact indicators, such as reliability of predictor …

Do Coaches Practice What They Preach? An Evaluation Of The Usage Of Evidence-Based Practices Among Probation Officer Coaches, Tamara Kang Jan 2017

Do Coaches Practice What They Preach? An Evaluation Of The Usage Of Evidence-Based Practices Among Probation Officer Coaches, Tamara Kang

Open Access Theses & Dissertations

Probation supervision has the potential to serve a rehabilitative function through the use of evidence-based practices (EBPs; practices supported by empirical research). Often, when administrators adopt EBPs in their agency, these programs may not be implemented with fidelity by probation officers who interact with offenders. Thus, there is a critical need to examine methods of increasing the effectiveness of implementing EBPs among officers. One method, peer mentoring (i.e., coaches), is gaining popularity; however, little is known about the highly-motivated officers who volunteer to be coaches. Consequently, this Dissertation investigates compliance with EBPs among officers who have volunteered to become coaches …

Are Narcissists More Likely To Support Terrorism? Exploring The Relationships Between Claiming Fake Religious Knowledge And Support For Violence, Peace, & Apathy., Adon Lee Neria Jan 2017

Are Narcissists More Likely To Support Terrorism? Exploring The Relationships Between Claiming Fake Religious Knowledge And Support For Violence, Peace, & Apathy., Adon Lee Neria

Open Access Theses & Dissertations

Religious overclaiming is a persons' tendency to claim to be familiar with fake religious concepts. In both Christian and Muslim samples, previous research has found a relationship between religious overclaiming and communal narcissism, as well as a relationship between religious overclaiming and support for religious violence. The present research extends previous work by including several different measures of narcissism including grandiose (agentic), vulnerable, communal, and collective narcissism to predict religious overclaiming for the Bible and the Qur'an. Moreover, the present research investigates the relationship between support for violence, peace, and apathy using an Internet Commenter task. The results found that …

Enterprise Risk Management In Responsible Financial Reporting, Robin B. Ewers Jan 2017

Enterprise Risk Management In Responsible Financial Reporting, Robin B. Ewers

Walden Dissertations and Doctoral Studies

Despite regulatory guidelines, unreliable financial reporting exists in organizations, creating undue financial risk-harm for their stakeholders. Normal accident theory (NAT) identifies factors in highly complex integrated systems that can have unexpected, undetected, and uncorrected system failures. High-reliability organization (HRO) theory constructs promote reliability in complex, integrated systems prone to NAT factors. Enterprise risk management (ERM) integrates NAT factors and HRO constructs under a holistic framework to achieve organizational goals and mitigate the potential for stakeholder risk-harm. Literature on how HRO constructs promote ERM in responsible integrated financial systems has been limited. The purpose of this qualitative, grounded theory study was …
