Model Misspecification And Assumption Violations With The Linear Mixed Model: A Meta-Analysis, Brandon Lebeau, Yoon Ah Song, Wei Cheng Liu Dec 2018

Model Misspecification And Assumption Violations With The Linear Mixed Model: A Meta-Analysis, Brandon Lebeau, Yoon Ah Song, Wei Cheng Liu

Department of Psychological and Quantitative Foundations Publications

This meta analysis attempts to synthesize the Monte Carlo literature for the linear mixed model under a longitudinal framework. The empirical type I error rate will serve as the effect size and Monte Carlo simulation conditions will be coded to serve as moderator variables. The type I error rate for the fixed and random effects will be explored as the primary dependent variable. Effect sizes were coded from 13 studies, resulting in a total of 4,002 and 621 effect sizes for fixed and random effects. Meta-regression and proportional odds models were used to explore variation in the empirical type ...


Using Bayesian Multilevel Models To Control For Multiplicity Among Means, Michael J. Zweifel Nov 2018

Using Bayesian Multilevel Models To Control For Multiplicity Among Means, Michael J. Zweifel

Public Access Theses and Dissertations from the College of Education and Human Sciences

It is well known that the Type I error rate will exceed α when multiple hypothesis tests are conducted simultaneously. This is known as Type I error inflation. The probability of committing a Type I error grows monotonically as the number as the number of hypothesis being tested increases. A class of methods, known as multiple comparison procedures, has been developed to combat this issue. However, in turn for maintaining the Type I error rate below α, multiple comparison procedures sacrifice power to correctly reject false hypotheses. The loss of power is exacerbated when variance heterogeneity is present.

Applying Conditional Distributions To Individuals: Using Latent Variable Models, Feng Ji Jun 2018

Applying Conditional Distributions To Individuals: Using Latent Variable Models, Feng Ji

Theses and Dissertations

This study proposes a new method to interpret individual results of psychological test batteries. The Mahalanobis distance is a commonly-used measure of how unusual an individual’s profile of scores is compared to a population of score profiles. In models in which there is a set of predictors and a set of dependent variables (e.g., cognitive abilities predicting academic abilities), it is useful to distinguish between a profile of dependent scores that is unusual because its profile of predictor scores is unusual and a profile of dependent scores that is unusual even after controlling for the predictors. The conditional ...


Misspecification Of The Random Effect Structure: Implications For The Linear Mixed Model, Brandon Lebeau May 2018

Misspecification Of The Random Effect Structure: Implications For The Linear Mixed Model, Brandon Lebeau

Department of Psychological and Quantitative Foundations Publications

The linear mixed model is a commonly used model for longitudinal or nested data due to its ability to account for the dependency of nested data. Researchers typically rely on the random effects to adequately account for the dependency due to correlated data, however serial correlation can also be used. If the random effect structure is misspecified (perhaps due to convergence problems), can the addition of serial correlation overcome this misspecification and allow for unbiased estimation and accurate inferences? This study explored this question with a simulation. Simulation results show that the fixed effects are unbiased, however inflation of the ...


Posterior Predictive Model Checking Of Local Misfit For Bayesian Confirmatory Factor Analysis, Chi Hang Au May 2018

Posterior Predictive Model Checking Of Local Misfit For Bayesian Confirmatory Factor Analysis, Chi Hang Au

Masters Theses

Posterior predictive model checks (PPMC) are one Bayesian model-data fit approach. Thus far, PPMC for Confirmatory Factor Analytic applications focused primarily on global fit evaluation, ignoring the nuanced information in local misfit diagnostics. This study developed a PPMC approach for local misfit and applied it to a test-taking motivation scale. If the PPMC approach is effective, fit conclusions derived from the PPMC approach should be congruent with the fit conclusions derived from the Frequentist approach. Number of item-pairs flagged as misfitting and number of disagreements were computed to evaluate congruence. Congruence is achieved if the number of item-pairs flagged as ...

This study investigated change in divergent thinking (DT), an indicator of creative potential, at two gender-specific residential summer camps. Additionally, this study examined whether the change in DT varied by gender and by the type of activities campers self-select. Quantitative methods, using a quasi-experimental design was used in order to understand differences in camper scores. A total of 189 youth, 100 girls, 89 boys, between the ages of 9 and 14 years participated in the current study. Participants were administered a modified version of Guilford's (1967) alternate uses task, a measure of DT, in which respondents were asked questions ...


Predicting Student Learning: The Roles Of Rapport, Immediacy, Learning Alliance, And Citizenship Behavior, Susan A. Talley Jan 2018

Predicting Student Learning: The Roles Of Rapport, Immediacy, Learning Alliance, And Citizenship Behavior, Susan A. Talley

Electronic Theses and Dissertations

Rapport, immediacy, learning alliance, classroom citizenship behavior, and observed classroom citizenship behavior were examined for their prediction of both affective and cognitive learning. The measure of observed classroom citizenship behavior was created for the purposes of the current study. Observed classroom citizenship behavior positively correlated with classroom citizenship behavior. Specifically, the involvement, affiliation, and courtesy subscales correlated with overall classroom citizenship behavior and their respective subscales but not with other citizenship behavior subscales. This suggests that only certain types of citizenship behaviors relate to the engagement or observation of those behaviors. Observed citizenship behavior was also found to be correlated ...


A Single-Subject Evaluation Of Facilitated Communication In The Completion Of School-Assigned Homework, Nancy A. Meissner Jan 2018

A Single-Subject Evaluation Of Facilitated Communication In The Completion Of School-Assigned Homework, Nancy A. Meissner

Dissertations & Theses

Few projects have combined quantitative and qualitative approaches in the analysis of facilitated communication as did this study of a 17-year-old nonverbal autistic male responding to homework questions using facilitated communication. Findings were consistent with prior studies: Tim was minimally able to produce correct responses independent of facilitator influence under controlled conditions; whereas, at least some typed messages in the spontaneous narratives appear to be his authentic communications independent of facilitator control.

An overview of the history of facilitated communication, its related research, and the heated debates around its validity are presented. Disparate findings between controlled and non-controlled circumstances are ...


Parental Characteristics And Parent-Child Relationship Quality In Families With Disabled Children, Tammy Young Jan 2018

Parental Characteristics And Parent-Child Relationship Quality In Families With Disabled Children, Tammy Young

Walden Dissertations and Doctoral Studies

Parenting can be very challenging, especially when raising a disabled child. Children with disabilities require more supports and are more likely to be abused. The parent-child relationship is an important factor in ensuring child welfare. Little research has focused on identifying the impact of parenting characteristics on raising a child with a disability. The purpose of this study was to examine whether parenting style, parenting competence, and parenting stress were predictors of parent-child relationship quality in parents of children with disabilities ages 3 to 12 years. This study was quantitative and used multiple linear regression to identify predictor variables of ...


Experiences Of Current Or Former Homeschool Students Who Report Adhd Symptoms, Melissa Felkins Jan 2018

Experiences Of Current Or Former Homeschool Students Who Report Adhd Symptoms, Melissa Felkins

Walden Dissertations and Doctoral Studies

Homeschooling is currently the fastest-growing educational population in the United States with an estimated 2 million students. Because 11% of school children have been diagnosed with attention deficit/hyperactivity disorder (ADHD), there are likely to be many children with ADHD symptoms in the homeschooling population. The purpose of this study was to extend knowledge of the experiences of homeschooling in this population to assist students with ADHD as well as their parents and educators to make informed educational decisions. The multiple intelligences theory provided the theoretical framework for this phenomenological study. The key research question was focused on how current ...


Assessing Executive Functioning In Young Children With Autism Spectrum Disorder, Julie Johnson Miller Jan 2018

Assessing Executive Functioning In Young Children With Autism Spectrum Disorder, Julie Johnson Miller

Walden Dissertations and Doctoral Studies

This study examined the inconsistency within research surrounding the relationship between executive functioning skills and autism symptomology in those being assessed for autism in early childhood (e.g., 34 to 60 months of age). Inconsistencies in current research connecting autism symptomology and executive dysfunction affect the best practice of practitioners that assess for disabilities. This study aimed to identify correlations between autism symptomology and executive functioning skills and whether combining autism symptomology and executive functioning skills assessments provide a more reliable classification as autism or non-autism. The framework foundation drew upon research that determined connections between those suffering from traumatic ...


Teacher Descriptions Of Oppositional Defiant Disorder And Bully-Victim Behavior Among Middle School Male Students, Randy Heller Jan 2018

Teacher Descriptions Of Oppositional Defiant Disorder And Bully-Victim Behavior Among Middle School Male Students, Randy Heller

Walden Dissertations and Doctoral Studies

While current psychological theory and research suggest conceptual associations between bullying and behavioral disorders, there is a gap in the literature examining such relationships. Although contemporary theories of aggression describe emotional, social, and cognitive risk factors that are common both, associations between bully-victim patterns and ODD have not been studied to date. This exploratory study addressed this gap by surveying 27 teachers to assess their reports of aggressive behaviors and socioemotional patterns of 58 male middle school students who were identified through school investigations as involved in bullying incidents. Between-group differences for students classified as bullies, victims, or bully-victims were ...


Response To Intervention Implementation And Special Education Eligibility In Rural Wisconsin Schools, Jessica Golburg Jan 2018

Response To Intervention Implementation And Special Education Eligibility In Rural Wisconsin Schools, Jessica Golburg

Walden Dissertations and Doctoral Studies

The purpose of this quantitative study was to investigate differences among special education enrollments for specific learning disabilities (SLD) and other disabilities within districts using school-wide response to intervention (RTI). Differences between rural and suburban school districts during the phases of the insufficient criterion rollout for SLD identification were explored as were environmental factors' impact on RTI implementation. Systems theory framed how concerns in rural districts impact the ability to use RTI data for special education enrollment. The research questions examined prevalence rates of SLD and other disabilities, compared RTI implementation fidelity in rural and suburban districts, and explored environmental ...


Effect Of Eustress, Flow, And Test Anxiety On Physical Therapy Psychomotor Practical Examinations, Todd Joseph Bourgeois Jan 2018

Effect Of Eustress, Flow, And Test Anxiety On Physical Therapy Psychomotor Practical Examinations, Todd Joseph Bourgeois

Walden Dissertations and Doctoral Studies

Students at the graduate level undergo higher levels of stress compared to their peers, and this stress is known to affect academic performance. Most of the research is focused on the negative aspect of stress. Positive psychology aspects, such as eustress and flow, are related to success in some activities; however, it is unknown whether these correlate with academic performance. Several stress-related theories-Yerkes-Dodson curve, cybernetics, conservation of resources, and choking under pressure-guided this quantitative study of the effects of eustress, flow, and cognitive test anxiety (CTA) on a psychomotor practical examination for physical therapy students. A sample of 192 physical ...


Predictive Relationship Between Anger And Violence In Canadian Secondary Students, Lawrence Alfred Deck Jan 2018

Predictive Relationship Between Anger And Violence In Canadian Secondary Students, Lawrence Alfred Deck

Walden Dissertations and Doctoral Studies

Violence among Canadian secondary students remains a concern for administrators, teachers, community members, and students. The purpose of this retrospective quantitative nonexperimental study was to examine the predictive relationship between anger and violence among secondary students in Canada using the Anger Regulation and Expression Scale (ARES). The general aggression model provided the framework for the study. Survey data were collected from 138 students using the ARES. Demographic data and archival data from students' school files were also collected. Results of receiver operator characteristic analysis and binary logistic regression indicated that the ARES total score provided fair to good predictive ability ...


Psychosocial Impacts On Young Adult Haitian Immigrant Students In The United States, Lucien Eugene Pierre, Ph. D. Jan 2018

Psychosocial Impacts On Young Adult Haitian Immigrant Students In The United States, Lucien Eugene Pierre, Ph. D.

Walden Dissertations and Doctoral Studies

Abstract

Many young adult Haitian immigrant students (YAHIS) move to the United States

hoping to achieve better lives. This growing population faces many challenges when

acculturating to a new country and educational system. Some obstacles include

inadequate family and social support, language barriers, limited education, distinct

cultural values, a lack of academic materials, a shortage of Haitian teachers, and

inadequate educational programs. These psychosocial factors often prevent Haitian

immigrants from succeeding in U.S. schools. This study explored YAHIS' experiences of

acculturation and education as they relate to these psychosocial factors. Qualitative

phenomenological techniques, guided by Adlerian theory, revealed the ...


The Experience Of Parenting Stress In Parents Of Twice-Exceptional Children, Christiane Wells Jan 2018

The Experience Of Parenting Stress In Parents Of Twice-Exceptional Children, Christiane Wells

Walden Dissertations and Doctoral Studies

Parenting stress (PS) is a phenomenon experienced by all parents to varying degrees due to the demands of meeting a child's needs. This distinct type of stress is caused by an imbalance between the perceived demands of parenting and the perceived coping resources available to parents. The construct of twice-exceptionality (2E) is defined as the co-occurrence of giftedness and disability or possessing both high cognitive abilities and at least 1 of 13 potential disabilities identified under the Individuals with Disabilities Education Act of 2004. The purpose of this study was to understand how PS is experienced by parents of ...


Teaching Experience And How It Relates To Teacher Impressions Of Work Intensification, Shannon Warren Jan 2018

Teaching Experience And How It Relates To Teacher Impressions Of Work Intensification, Shannon Warren

Walden Dissertations and Doctoral Studies

Changes in schools can cause teachers to experience an intensification of work as they strive to meet expectations of students, parents, and administrations. This study includes an examination of factors that may lead to work intensification (WI) for teachers. The study also includes an examination of how years of experience and teacher perceptions of administrative support may moderate the relationship between teachers' impressions of WI and their job satisfaction. Based on equity theory, data were collected using a Likert-type scale survey distributed to 9 public high schools in southern California. A test for correlation was performed followed by a hierarchal ...


Facilitating Collaboration Among School And Community Providers In Children's Mental Health, Holly J. Curran Jan 2018

Facilitating Collaboration Among School And Community Providers In Children's Mental Health, Holly J. Curran

Walden Dissertations and Doctoral Studies

Interprofessional collaboration among school-based and community-based mental health providers in children's mental has been studied in relation to specific providers and as part of program evaluation; however, limited information exists as to how to overcome barriers to collaborative relationships. This study describes the experiences of school and community mental health service providers and those who supervise them. Using phenomenological methodology, three focus-group interview transcripts were analyzed by identifying recurrent themes relevant to the experience of collaboration from school and community providers' perspectives. Although participants viewed aspects of collaboration positively, barriers frequently interfered with collaborative relationships. Support for collaboration from ...


Demographics, Self-Autonomy, And Relationships As Predictors Of Substance Use Among Community College Learners, F. Lashell Robertson Jan 2018

Demographics, Self-Autonomy, And Relationships As Predictors Of Substance Use Among Community College Learners, F. Lashell Robertson

Walden Dissertations and Doctoral Studies

Abuse of prescription and over-the-counter substances other than alcohol is becoming a prevalent issue; therefore, it is important to identify factors that may help predict risk for this abuse. Some demographic and situational factors have been identified for traditional 4-year college students. However, less is known about community college students, who enter college less academically prepared and may be still enmeshed with family and peer groups from high school. In this correlational study, predictors of substance abuse other than alcohol were explored among a convenience sample of 118 students from an American community college. The research question was developed based ...
