Statistical Analyses Of The Resilience Function, Joseph W. Houpt, Daniel R. Little

Psychology Faculty Publications

The extent to which distracting information influences decisions can be informative about the nature of the underlying cognitive and perceptual processes. In a recent paper, a response time-based measure for quantifying the degree of interference (or facilitation) from distracting information termed resilience was introduced. Despite using a statistical measure, the analysis was limited to qualitative comparisons between different model predictions. In this paper, we demonstrate how statistical procedures from workload capacity analysis can be applied to the new resilience functions. In particular, we present an approach to null-hypothesis testing of resilience functions and a method based on functional principal components …

A Case Study: Parents' Views Of The Program Everlasting Peace, Meshonda Moore

Walden Dissertations and Doctoral Studies

Juvenile crime among females is on the rise in the United States and is currently at an all-time high. Girls who are at risk for committing juvenile crime are at greater risk than boys for experiencing sexual trauma and exploitation as well as depression. Additionally, adolescent females have a higher rate of status-offense reoffending than do adolescent males. Using Kubeka's conceptualization of trauma theory, the purpose of this case study was to determine whether Everlasting Peace (EP), an evidence-based counseling program in Georgia, successfully provided gender-specific treatment for female juvenile offenders. Data were collected through interviews with 20 parent/guardian of …

Self-Expansion And Romantic Partner Request For Friendship Termination, Emily C. Wages

Scripps Senior Theses

According to self-expansion theory, there is an innate drive to gain new resources, identities, and perspectives, which causes people to seek and maintain interpersonal relationships. However, an individual’s relationship partners may come into conflict with each other. In the current research, 656 adults in established monogamous romantic relationships completed an online questionnaire about romantic partners asking them to give up a friendship. The researcher explored the prevalence of this friendship interference phenomenon and its relationship to sources of self-expansion. The amount of self-expansion provided by a friendship was manipulated through vignettes. Additional measures assessed the relationship between amount of self-expansion …

The Role Of Illness Intrusiveness And Personal Control In Mediating The Relationship Between The Intravenous Immunoglobulin Treatment Experience And Quality Of Life In Neurological Autoimmune Patients, Pamela Jane Gennari

Walden Dissertations and Doctoral Studies

Intravenous immunoglobulin (IVIG) is a common treatment for the neurological autoimmune diseases multiple sclerosis, multifocal motor neuropathy, myasthenia gravis, and chronic inflammatory demyelinating polyneuropathy. However, there is scant literature regarding the psychological effects of this treatment on quality of life (QOL). Using illness intrusiveness theory and personal control theory, this correlational, cross-sectional study examined the relationship between the IVIG treatment experience and QOL in neurological autoimmune patients. Surveys were employed to collect data from 79 patients at a neurological infusion center in Phoenix, AZ. Quantitative analyses included correlation, multiple regression, and mediation analyses to determine whether (a) IVIG treatment experience …

Comparing The Relationship Between Personality And Determined Variables With Generalized Expectancy For Success, Christina M. Harris

Department of Psychology: Presentations

Past literature has shown that expectancies of success influence how an individual behaves in certain situations (Donat & Sassenroth) and drives motivation and action. GESS is also related to achievement (Weiner, 1985). The current study looks at self-confidence, locus of control, frequency of self-reinforcement, family type raised in, family income, and gender and the relationship they share with expectancies of success. The proposed study used data from 391 undergraduates at the University of Nebraska- Lincoln and nested models were compared against a full model of predictors of expectancies for success, including a personal and a determined model which were then …

The Cyber Aggression In Relationships Scale: A New Multidimensional Measure Of Technology-Based Intimate Partner Aggression, Laura E. Watkins, Rosalita C. Maldonado, David Dilillo

Department of Psychology: Faculty Publications

The purpose of this study was to develop and provide initial validation for a measure of adult cyber intimate partner aggression (IPA): the Cyber Aggression in Relationships Scale (CARS). Drawing on recent conceptual models of cyber IPA, items from previous research exploring general cyber aggression and cyber IPA were modified and new items were generated for inclusion in the CARS. Two samples of adults 18 years or older were recruited online. We used item factor analysis to test the factor structure, model fit, and invariance of the measure structure across women and men. Results confirmed that three-factor models for both …

Referral And Treatment Settings For Pregnant Women, Linda D. O'Daniel

Walden Dissertations and Doctoral Studies

Drug and alcohol addiction in pregnant women is a significant public health issue. The purpose of this study was to assess drug and alcohol addiction in pregnant women and the setting in which they sought service or treatment to determine whether U.S. census regions and race data could predict the type of addiction service or treatment that pregnant addicts chose. The theories of self-efficacy, cognitive behavioral therapy, and rational emotive behavioral therapy were used as the theoretical framework for this study. The research questions were used to examine whether there was a relationship between the source of addiction treatment referral …

The Embodied Causal Learner, Vanja Vlajnic

Seton Hall University Dissertations and Theses (ETDs)

Traditionally, cognitive psychology has assumed a disembodied learner and thinker. However, an emerging approach known as embodiment posits that seemingly irrelevant motor or perceptual aspects of a task can affect higher-level cognition. The findings from such embodiment studies have also been shown to extend into real-world settings. For example, children who were taught mathematical concepts while required to make gestures consistent with the problem’s solution were more likely, on average, to apply the mathematical concepts correctly in the future (Cook, Mitchell, & Goldin-Meadow, 2008). For this specific study, the area of causal learning was examined.

The primary goal of this …

The Effects Of Mindfulness On Affect And Substance Use, Alicia D. Carter

Honors College Theses

Previous studies have explored the impact of mindfulness on Big 5 personality traits, personality disorders, suicidal ideation, and alcohol use; additionally, mindfulness-based interventions (MBIs) have been used to treat individuals suffering from depression and anxiety. However, the practical application of mindfulness has been complicated by contradictory findings in the literature and inconsistent conceptualizations of the construct. The current study sought to investigate potential relationships between types of mindfulness, facets of mindfulness, substance use, and affect. Participants completed a battery of questionnaires related to mindfulness, correlates of neuroticism (i.e., depression, anxiety, and subjective happiness), and drinking-related consequences. Correlational analyses revealed significant …

Strategies And Resources To Enhance Test Evaluation And Selection, Janet F. Carlson, Nancy Anderson

Buros Center: Professional Staff Publications

Testing serves an important function for SLPs in offering an evidence base that is useful in screening, diagnosing, monitoring progress, and documenting outcomes. Tests are used to measure diverse constructs such as communication, literacy, oral and written language, receptive and expressive vocabulary, articulation, phonological awareness and processing, and auditory perception and processing. In addition, specific impairments may require specialized measures to evaluate conditions such as stuttering and orthographic competence.

When using tests to diagnose language impairments, Betz, Eickhoff, and Sullivan (2013) suggest that SLPs consider carefully a test’s psychometric properties, particularly because of the “increasing emphasis on evidence-based practice, specifically, …

Can Non-Haptic Manipulation Of Temperature Influence The Same Emotions As Ostracism?, Rebecca Ann Oglesby

Theses and Dissertations

I explored the possibility that temperature can alter the same variables affected by ostracism (i.e., being ignored and excluded): belonging, control, meaningful existence, and self-esteem need satisfaction, feelings of ostracism, mood, and loneliness. According to the theory of embodied cognition, individuals can associate physical warmth with social intimacy, as well as cold temperatures with social isolation (Zhong & Leonardelli, 2008; IJzerman et al., 2012). Bargh and Shalev (2012) found that participants holding a cold pack reported higher loneliness than participants holding a neutral or warm pack. My study expands upon Bargh and Shalevâ??s (2012) findings by examining more emotions frequently …

The Effects Of Task Criticality And Target Modality On A Simulated Battlefield Search Task, Julie A. Hanson

Psychology Theses & Dissertations

Warfighters must rely on lengthy instruction manuals when asked to perform tasks in critical environments. These instruction manuals are predominantly written in text and rarely include images. Several theoretical frameworks, including the Pictorial Superiority Effect, posit images to be more effective forms of instruction for short-term memory recall tasks. It is unclear whether pictures are superior forms of instruction for use in tasks with potential life-threatening consequences. Recently, studies have attempted to define and manipulate task criticality to determine the effects a critical scenario may have on operator performance. Findings have been equivocal, perhaps because of the ambiguity associated with …

Acceptance And Commitment Therapist Views On The Sacred, Amal Abuzalaf Mull

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Spirituality and/or religion (S/R) continue to be an important topic in mental health treatment, especially regarding their relationship to a psychotherapist’s theoretical orientation and practice with clients. Given the increased relevance of spirituality to third-wave cognitive behavioral therapies, the current study explores the S/R of Acceptance and Commitment Therapy (ACT) psychotherapists and how their S/R is associated to their attitudes and behaviors within mental health and their use of ACT. Online surveys were administered, producing a sample of 97 ACT psychotherapists in the United States. Results indicated low levels of religiosity and high levels of spirituality among ACT psychotherapists in …

Development And Validation Of A State-Based Measure Of Emotion Dysregulation: The State Difficulties In Emotion Regulation Scale (S-Ders), Jason M. Lavender, Matthew T. Tull, David Dilillo, Terri Messman-Moore, Kim L. Gratz

Department of Psychology: Faculty Publications

Existing measures of emotion dysregulation typically assess dispositional tendencies and are therefore not well suited for study designs that require repeated assessments over brief intervals. The aim of this study was to develop and validate a state-based multidimensional measure of emotion dysregulation. Psychometric properties of the State Difficulties in Emotion Regulation Scale (S-DERS) were examined in a large representative community sample of young adult women drawn from four sites (N = 484). Exploratory factor analysis suggested a four-factor solution, with results supporting the internal consistency, construct validity, and predictive validity of the total scale and the four subscales: Nonacceptance (i.e., …

Application Of Item Response Theory To Measures Of Verbal Learning, Indrani K. Thiruselvam

Dissertations (1934 -)

This study utilized item response theory (IRT) methods to investigate if item parameters of select trials in the California Verbal Learning Test-Second Edition (CVLT-II; Delis, Kramer, Kaplan, & Ober, 2000) and the Logical Memory subtests of the Wechsler Memory Scales – Fourth Edition (WMS-IV; Wechsler, 2009) vary as a function of the serial position effect. In addition, this study compared the effectiveness of CVLT-II and LM in quantifying verbal memory functioning, and determined if a weighted scoring approach improves the quantification of verbal memory. Archival data from 755 individuals (516 college students, 239 patients at a neuropsychology clinic) were utilized …

Mixed-Effects Location-Scale Models For Conditionally Normally Distributed Repeated-Measures Data, Ryan Walters

Department of Psychology: Dissertations, Theses, and Student Research

Hypotheses about psychological processes are most frequently dedicated to individual mean differences, but individual differences in variability are likely to be important as well. The mixed-effects location-scale model estimates individual differences in both mean level and variability in a single model, and represents an important advance in testing variability-related hypotheses. However, the mixed-effects location-scale model remains relatively novel to empirical scientists as statistical software is often handicapped by more complex models and a paucity of methodological studies exist examining the statistical properties of this model.

This dissertation investigates the mixed-effects location-scale model through the development of open-source software for its …

Examining The Measurement Invariance Of The Minnesota Multiphasic Personality Inventory-2-Restructured Form Internalizing Specific Problem Scales In African- American And Caucasian Men, Megan Anne Brokenbourgh

Psychology Theses & Dissertations

Test bias has long been an area of investigation in the personality assessment literature, including the MMPI-2-RF. Research on previous versions of the MMPI and MMPI-2-RF has pointed to mixed results. The current study aims to examine test bias on the MMPI-2-RF’s nine Internalizing Specific Problem Scales by examining measurement invariance using MIMIC modeling and investigating differential item functioning (DIF). After removal of invalid protocols, the first sample consisted of 2,980 protocols from various settings requested from Pearson (255 African American and 2,755 Caucasian protocols). The second sample consisted of 1,379 valid protocols from psychiatric inpatient settings (1,245 Caucasian and …

Effects Of Varying Degrees Of Fixed And Random Responding On The Validity Of Score Interpretation For The Sp And Psy-5 Scales Of The Mmpi-2-Rf, Joseph Brooks Minifie

Psychology Theses & Dissertations

The Minnesota Multiphasic Personality Inventory – 2 Restructured Form (MMPI-2- RF; Tellegen & Ben-Porath, 2008/2011) is a widely used self-report measure of psychopathology and personality. However, the self-report format of the MMPI-2-RF suggests that interpretation of its scales and the clinical recommendations that follow are vulnerable to invalid response styles. This dissertation builds upon previous research (Handel, Ben-Porath, Tellegen, & Archer, 2010) to examine the effect of random and fixed responding, as measured by the VRIN-r and TRIN-r Scales, on the 28 SP and PSY-5 Scales. A computer simulation procedure was used to insert increasing degrees of inconsistent responding into …

Development And Preliminary Validation Of A Nonmedical Prescription Drug Motives Questionnaire, Lauren Ashleigh Milner

Graduate Theses and Dissertations

The prevalence of nonmedical prescription drug (NMPD) use continues to increase among emerging adult populations; however, little is known about the motivations behind this use. The current study aimed to extend previous research by developing and validating the first known comprehensive NMPD motives measure. As such, the primary focus of the current study was to examine evidence for the reliability and validity of the NMPD Motives Questionnaire by assessing the factor structure, internal consistency, and construct validity of the motives scale. Participants were drawn from a larger study of college student substance use behaviors and attitudes (N = 1,427; Mage= …

Time Series Analysis For Psychological Research: Examining And Forecasting Change, Andrew T. Jebb, Louis Tay, Wei Wang, Qiming Huang

Publications and Research

Psychological research has increasingly recognized the importance of integrating temporal dynamics into its theories, and innovations in longitudinal designs and analyses have allowed such theories to be formalized and tested. However, psychological researchers may be relatively unequipped to analyze such data, given its many characteristics and the general complexities involved in longitudinal modeling. The current paper introduces time series analysis to psychological research, an analytic domain that has been essential for understanding and predicting the behavior of variables across many diverse fields. First, the characteristics of time series data are discussed. Second, different time series modeling techniques are surveyed that …

Development Of A Psychological Assessment Battery To Measure Client Beliefs About The Effectiveness Of Psychotherapy, Christopher Peavey

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

The author attempted to develop a brief scale to measure clients' beliefs about the effectiveness of psychotherapy. The study is an early pilot study to determine if the scale can predict therapy outcomes. While the scale did differ significantly between clients who were active in therapy and those who were not, higher scores on the instrument were not indicative of greater involvement. Possibilities for future research to refine the instrument are discussed.

A Signal Detection Experiment With Limited Number Of Trials, Tadamasa Sawada

MODVIS Workshop

Signal detection theory has been well accepted in vision science to measure human sensitivity to stimuli in a Psychophysical experiment. The theory is formulated so that the measured sensitivity is independent from a response bias (criterion). The formulation is based on an assumption that number of trials in the experiment is infinite but this assumption cannot be satisfied in practice. The assumption came from two normal distributions used in the formulation. The distributions respectively represent a set of signal trial and that of noise trials in the experiment. In this study, I will show how the violation of the assumption …

Binocular 3d Motion Perception As Bayesian Inference, Martin Lages, Suzanne Heron

MODVIS Workshop

The human visual system encodes monocular motion and binocular disparity input before it is integrated into a single 3D percept. Here we propose a geometric-statistical model of human 3D motion perception that solves the aperture problem in 3D by assuming that (i) velocity constraints arise from inverse projection of local 2D velocity constraints in a binocular viewing geometry, (ii) noise from monocular motion and binocular disparity processing is independent, and (iii) slower motions are more likely to occur than faster ones. In two experiments we found that instantiation of this Bayesian model can explain perceived 3D line motion direction under …

The Effects Of Ordinal Data On Coefficient Alpha, Kathryn E. Pinder

Masters Theses, 2010-2019

Given coefficient alpha’s wide prevalence as a measure of internal reliability, it is important to know the conditions under which it is an appropriate estimate of reliability. The present paper explores alpha’s assumption of uncorrelated errors when used with ordinal data. Alpha overestimates true reliability when correlated errors are present. In this paper, I use a simulation study to recreate three mechanisms proposed to create correlated errors in ordinal data. The first mechanism, misclassification error, occurs when there are correlated measurement errors present in the data. The second mechanism, grouping error, occurs when there are not enough categories to represent …

Propensity Score Matching In Higher Education Assessment, Heather D. Harris

Masters Theses, 2010-2019

The applied nature of higher education assessment does not lend itself to rigorous experimental research designs. However, assessment practitioners would like to make claims about the influence of educational programs on student learning outcomes. Propensity score matching (PSM) methods are quasi-experimental techniques that allow researchers to control for known confounding variables. In the context of higher education, PSM techniques allow assessment practitioners to control for confounding variables related to students’ self-selected participation in university programs. Research and recommendations on how to apply PSM techniques are scattered throughout several disciplines. However, additional research is needed to evaluate how well PSM techniques …

Persons Can Speak Louder Than Variables: Person-Centered Analyses And The Prediction Of Student Success, Elisabeth M. Pyburn

Masters Theses, 2010-2019

In order to ensure that analyses are appropriate for one’s research question(s), it is important to consider whether a person-centered or variable-centered approach is needed. Person-centered approaches are often not considered in situations for which they would be appropriate. To that end, a description of the characteristics and procedures of two common person-centered analyses (cluster analysis and mixture modeling) are provided. Although both analyses accomplish the same general aim – to group persons based on their similarity on a series of variables, thus providing ease of interpretation – the methods employed for each analysis differ considerably. As illustration, both analyses …

The Effects Of A Planned Missingness Design On Examinee Motivation And Psychometric Quality, Matthew S. Swain

Dissertations, 2014-2019

Assessment practitioners in higher education face increasing demands to collect assessment and accountability data to make important inferences about student learning and institutional quality. The validity of these high-stakes decisions is jeopardized, particularly in low-stakes testing contexts, when examinees do not expend sufficient motivation to perform well on the test. This study introduced planned missingness as a potential solution. In planned missingness designs, data on all items are collected but each examinee only completes a subset of items, thus increasing data collection efficiency, reducing examinee burden, and potentially increasing data quality. The current scientific reasoning test served as the Long …

Extending An Irt Mixture Model To Detect Random Responders On Non-Cognitive Polytomously Scored Assessments, Mandalyn R. Swanson

Dissertations, 2014-2019

This study represents an attempt to distinguish two classes of examinees – random responders and valid responders – on non-cognitive assessments in low-stakes testing. The majority of existing literature regarding the detection of random responders in low-stakes settings exists in regard to cognitive tests that are dichotomously scored. However, evidence suggests that random responding occurs on non-cognitive assessments, and as with cognitive measures, the data derived from such measures are used to inform practice. Thus, a threat to test score validity exists if examinees’ response selections do not accurately reflect their underlying level on the construct being assessed. As with …

Examining The Performance Of The Metropolis-Hastings Robbins-Monro Algorithm In The Estimation Of Multilevel Multidimensional Irt Models, Bozhidar M. Bashkov

Dissertations, 2014-2019

The purpose of this study was to review the challenges that exist in the estimation of complex (multidimensional) models applied to complex (multilevel) data and to examine the performance of the recently developed Metropolis-Hastings Robbins-Monro (MH-RM) algorithm (Cai, 2010a, 2010b), designed to overcome these challenges and implemented in both commercial and open-source software programs. Unlike other methods, which either rely on high-dimensional numerical integration or approximation of the entire multidimensional response surface, MH-RM makes use of Fisher’s Identity to employ stochastic imputation (i.e., data augmentation) via the Metropolis-Hastings sampler and then apply the stochastic approximation method of Robbins and Monro …
