A Factor-Analytic Study Of The Learning And Study Strategies Inventory, Second Edition (Lassi-2) In A Sample Of University Students, Kwoneathia Hill

Electronic Theses and Dissertations

The present study sought to provide a better understanding of the factor structure of the Learning and Study Strategies Inventory, Second Edition (LASSI-2) at the item to scale level (via confirmatory factor analysis) and to expand the LASSI-2's psychometric properties (i.e., means, standard deviations, alpha coefficients, and correlations of the LASSI-2's scale scores) as well as examine for potential sex differences in the LASSI-2 scale scores (via t tests with Cohen's d also being calculated) with a sample of 420 university students. The means, standard deviations, and alpha coefficients of the 10 LASSI-2 scales for the current data appeared comparable …

Using The Counseling Center Assessment Of Psychological Symptoms - 34 (Ccaps-34) To Predict Premature Termination In A College Counseling Sample, Sean B. Hall

Counseling & Human Services Theses & Dissertations

Swift and Greenberg (2012) observed that variables influencing the decision to drop out fluctuate according to the primary presenting problem, the amount of structure in therapy, the length of treatment, and the clinical setting. Due to these reports, researchers may focus on predictors of premature termination (PT) in treatment settings where the unique situational characteristics may have an idiosyncratic influence on the decision to withdraw from services (Phillips, 1985; Swift & Greenberg, 2012). The purpose of this exploratory study was to examine client characteristics that impact dropout in University Based Clinics (UBC). Results from the logistic regression analysis indicated higher …

The Role Of Metrical Structure In Tonal Knowledge Acquisition, Matthew Rosenthal

UNLV Theses, Dissertations, Professional Papers, and Capstones

Experienced listeners possess a working knowledge of pitch structure in Western music, such as scale, key, harmony, and tonality, which develops gradually throughout childhood. It is commonly assumed that tonal representations are acquired through exposure to the statistics of music, but few studies have investigated potential learning mechanisms directly. In Western tonal music, tonally stable pitches not only have a higher overall frequency of occurrence, but they may occur more frequently at strong than weak metrical positions, providing two potential avenues for tonal learning. Two experiments employed an artificial grammar learning paradigm to examine tonal learning mechanisms. During a familiarization …

Mixture Latent Markov Modeling: Identifying And Predicting Unobserved Heterogeneity In Longitudinal Qualitative Status Change, Mo Wang, David Chan

Research Collection School of Social Sciences

There are many areas of organizational research where we may be concerned with subgroup differences in status change profiles. The purpose of this article is to illustrate, using a real data set on retirees' postretirement employment statuses (PES), how mixture latent Markov modeling may be applied to substantive research in organizational settings to identify population subgroups with varying status change profiles and examine their correlates, by modeling unobserved heterogeneity in longitudinal qualitative changes. Steps in the modeling process are highlighted and limitations, cautions, recommendations, and extensions of the technique are discussed.

An Extension Of Sic Predictions To The Wiener Coactive Model, Joseph W. Houpt, James T. Townsend

Psychology Faculty Publications

The survivor interaction contrasts (SIC) is a powerful measure for distinguishing among candidate models of human information processing. One class of models to which SIC analysis can apply are the coactive, or channel summation, models of human information processing. In general, parametric forms of coactive models assume that responses are made based on the first passage time across a fixed threshold of a sum of stochastic processes. Previous work has shown that the SIC for a coactive model based on the sum of Poisson processes has a distinctive down--up--down form, with an early negative region that is smaller than the …

A Multiple Regression Analysis Of Personality’S Impact On Actuarial Exam Performance, Matthew Ciaffone

Honors Projects in Mathematics

Existing literature indicates that there is some connection between personality and both academic and work-related performance. The author's intent for the research described herein is to explore this connection for students majoring in actuarial mathematics with regard to their performance on actuarial certification exams. Specifically, using the five-factor model of personality, the author seeks to predict the number of attempts required to pass the first two exams in the process (Exam 1/P - probability; Exam 2/FM - financial mathematics) using measures of the five dimensions of the five-factor model (openness to experience, conscientiousness, extraversion, agreeableness, and emotional stability) through regression …

Self-Monitoring Personality At Work Revisited: A Comparative Meta-Analysis, Michael P. Wilmot

Department of Agricultural Leadership, Education, and Communication: Dissertations, Theses, and Student Research

The validity of self-monitoring personality in work and organizational settings was reexamined. Comparative meta-analyses using both random-effects and fixed-effects models were conducted (349 total samples; N = 75,811) to test the relationship between self-monitoring personality and work-related and demographic correlates, as well as the reliability of the self-monitoring measures. Contributions were made to the literatures of self-monitoring and meta-analysis. Self-monitoring: Results indicated that self-monitoring related to a number of relevant organizational outcomes, including job effectiveness and success, leadership, and ingratiation. Some results ran contrary to the prior meta-analysis (Day, Shleicher, Unckless, & Hiller, 2002). Meaningful differences were found between the …

The Hormonal Correlates Of Stress And Posttraumatic Stress Disorder Symptoms In Female Veterans, Meghan Pierce

UNLV Theses, Dissertations, Professional Papers, and Capstones

With the increase of female veterans serving in the military, a better understanding of posttraumatic stress disorder is needed to provide comprehensive treatment. This study examines salivary cortisol in female veterans with PTSD, female veterans without PTSD, civilian females with PTSD and healthy controls. The Posttraumatic Stress and Beck Depression Inventory-II were used to assess posttraumatic stress and depressive symptoms. Saliva samples were collected at bedtime and awakening, as well as in response to the Trier Social Stress Test. Significant results were not found for diurnal cortisol levels [ F (3, 11)= .979, p < .05] or stress cortisol levels (F (3,12) = 1.140, p >.05). …

Faking In Personality Assessments: An Investigation Of A Method Factor Measure Of Faking, Raven Lynnette Worthy

Masters Theses and Doctoral Dissertations

The goal of this study was to assess the efficacy of a newly developed "method factor" measure of faking to control for the effects of faking when personality tests are used to predict performance criteria. Traditional measures of faking, such as social desirability scales, have not been found to adequately control for faking. This study assessed the adequacy of the newly developed measure. When controlling for faking, as measured by the method factor, the validity of conscientiousness as a predictor of undergraduate GPA was larger. Additionally, the nature of the method factor across experimental conditions was investigated. The method factor …

A Multigroup Analysis Of Reintegrative Shaming Theory: An Application To Drunk Driving Offenses, Elizabeth J. Dansie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A restorative justice alternative to crime prevention termed reintegrative shaming theory by Braithwaite has seen increased attention as an alternative to retributive justice, although empirical investigations of its efficacy are limited. The purpose of the present study was to test confirmatory measurement and structural models of reintegrative shaming theory in order to assess the underlying theoretical model and the application of this theory in response to drunk driving offenses. Nine latent constructs were included in these models: reintegration, stigmatization, perceived fairness, self esteem, shame-guilt, embarrassment-exposure, unresolved shame, offender responsibility, and family support.

Multigroup structural equation modeling was used to assess …

Factors Moderating The Association Between Multiple Rating Sources Of Geriatric Depression: Self, Informant, And Physician, Daniel J. Hatch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Late-life depression is a major public health concern, associated with poor health outcomes, including doubling of dementia risk. Psychiatric evaluation is impractical in large epidemiological studies, which instead typically rely on self/informant reports, which are subject to various biases (stigma, recall). Few studies have addressed level of agreement between sources. This study examined associations between these sources and assessed whether subject and informant variables moderated these associations. In a population-based study of dementia in Cache County, Utah (2002-5), 1,480 subjects completed an in-depth clinical assessment (CA). Major depression was assessed via the self-report Patient Health Questionnaire-9 (PHQ-9) and informant-rated Neuropsychiatric …

Nice Guys Finish Fast And Bad Guys Finish Last: Facilitatory Vs. Inhibitory Interaction In Parallel Systems, Ami Eidels, Joseph W. Houpt, Nicholas Altieri, Lei Pei, James T. Townsend

Psychology Faculty Publications

Systems Factorial Technology is a powerful framework for investigating the fundamental properties of human information processing such as architecture (i.e., serial or parallel processing) and capacity (how processing efficiency is affected by increased workload). The Survivor Interaction Contrast (SIC) and the Capacity Coefficient are effective measures in determining these underlying properties, based on response-time data. Each of the different architectures, under the assumption of independent processing, predicts a specific form of the SIC along with some range of capacity. In this study, we explored SIC predictions of discrete-state (Markov process) and continuous-state (Linear Dynamic) models that allow for certain types …

Examining Construct Stability Across Career Stage Cohorts, Deborah L. Kinney

Online Theses and Dissertations

The purpose of this study is to evaluate construct stability of the same certification test taken at different points in a test taker's career, taking into account changes is experience over time. A single medical certification exam administration was used to analyze the construct stability of the certification exam across testing cohorts at varied stages in their medical careers. The Rasch model was used for item analysis to calibrate the difficulty hierarchy of the exam items for each cohort. Correlations between the item difficulty hierarchies for each cohort supported the overall construct stability of the certification exam. Individual item function …

Prediction Of Air Traffic Controller Trainee Selection And Training Success Using Cognitive Ability And Biodata, Karen D. Fox

Walden Dissertations and Doctoral Studies

The Federal Aviation Administration (FAA) has experienced decreased return on investment caused by hiring too many air traffic controller specialists (ATCSs) who performed poorly in field training, thus failing to become certified professional controllers (CPCs). Based on Schmidt and Hunter's theory of job performance and biodata theory, this quantitative, archival study examined whether factors of cognitive ability and biodata could predict job performance status of 2 generations of ATCSs, poststrike (PS) and next generation (NG) controllers. For each generation of controllers, binary logistic regression analysis was conducted to determine if any of the independent variables---transmuted composite (TMC) score for PS …
