The Influence Of Covariate Measurement Error On Treatment Effect Estimates And Numeric Balance Diagnostics Following Several Common Methods Of Propensity Score Matching: A Simulation Study, Heather D. Harris 2018 James Madison University

The Influence Of Covariate Measurement Error On Treatment Effect Estimates And Numeric Balance Diagnostics Following Several Common Methods Of Propensity Score Matching: A Simulation Study, Heather D. Harris

Dissertations

In applied intervention studies, researchers frequently aim to make inferences about the impact of a treatment program on participants. However, applied researchers are often faced with threats to the internal validity of their studies, or the extent to which changes in participants’ outcomes can be attributed to the intervention. When researchers are unable to randomly assign study participants to treatment conditions, changes in the intervention outcome might be confounded with systematic differences in participants’ baseline characteristics. Propensity score matching is one technique that allows researchers to account for threats to the internal validity of a study. Specifically, using propensity score ...


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

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 ...


Beyond Motivation: Differences In Score Meaning Between Assessment Conditions, Nikole Gregg 2018 James Madison University

Beyond Motivation: Differences In Score Meaning Between Assessment Conditions, Nikole Gregg

Masters Theses

Written communication is a skill necessary for not only the success of undergraduate students, but for post-graduates in the workplace. Furthermore, according to employers the writing skills of post-graduates tend to be below expectations. Therefore, the assessment of such skills within higher education is in high demand. Written communication assessments tend to be administered in one of two conditions: 1) course embedded and 2) a low-stakes, non-embedded condition. The current study investigated possible construct-irrelevant variance in writing assessment scores by using data from a mid-sized public university in the Mid-Atlantic region of the United States. Specifically, 157 student products were ...


Using Instructed Response Itmes To Compare Inattentive Responding Across Paper And Online Modalities: Measuring Research Participant Inattention, Olivia B. Brooks 2018 Eastern Washington University

Using Instructed Response Itmes To Compare Inattentive Responding Across Paper And Online Modalities: Measuring Research Participant Inattention, Olivia B. Brooks

EWU Masters Thesis Collection

It is important to examine the equivalence of paper and online data collection methods across several domains. The current study compared paper versus online modalities from a data quality standpoint, with a specific focus on inattentive (i.e., careless) responding by using an easily-implemented method to capture participants’ careless responses: interspersing instructed response items (e.g., “Please select option 3, ‘Strongly disagree,’”) throughout a collection of 15 established measures. A between-subjects design compared the percentage of instructed response items missed (hence, inattentive responses) across three conditions: 1) lab paper, 2) lab online, and 3) non-lab online. The non-lab online condition ...

Child Sexual Abuse And Prenatal Care: Understanding Screening, Modifications, And Proper Care, Wendy Abbott-Egnor

Walden Dissertations and Doctoral Studies

Research has shown that 1 in 9 women in prenatal care have a history of childhood sexual abuse. Pregnant women with a history of childhood sexual abuse are at increased risk of depression, somatization, preterm contractions, posttraumatic stress symptomology, and re-traumatization. The purpose of this study was to bridge the gap in literature between research and practice. Data was collected from practitioners regarding the care and treatment of pregnant women with a childhood sexual abuse history. It was hypothesized that screening practices and modification to care and treatment based on practitioner knowledge of prior sex abuse history will vary by ...


Psychometric Properties Of A Working Memory Span Task, Juan M. Alzate Vanegas 2018 University of Central Florida

Psychometric Properties Of A Working Memory Span Task, Juan M. Alzate Vanegas

Honors Undergraduate Theses

The intent of this thesis is to examine the psychometric properties of a complex span task (CST) developed to measure working memory capacity (WMC) using measurements obtained from a sample of 68 undergraduate students at the University of Central Florida. The Grocery List Task (GLT) promises several design improvements over traditional CSTs in a prior study about individual differences in WMC and distraction effects on driving performance, and it offers potential benefits for studying WMC as well as the serial-position effect. Currently, the working memory system is composed of domain-general memorial storage processes and information-processing, which involves the use of ...


Effect Of Personality Type On Exercise Modality Choice, Michael Koskiniemi 2018 Walden University

Effect Of Personality Type On Exercise Modality Choice, Michael Koskiniemi

Walden Dissertations and Doctoral Studies

The unhealthy lifestyles of many individuals throughout the world put them at risk for health problems, including infectious disease; endocrine, circulatory, cardiovascular, respiratory, and digestive disorders; and obesity. The modifiable health risks from unhealthy lifestyles account for a sizable percentage of health care costs. Regular exercise is recommended for health. However, currently little research exists regarding how individuals select which exercise regimens (personal training, group exercise, multimedia exercise, and self-directed) to follow. Selection of regimens that are based on one's personality may lead to regular, long-term exercise behavior. The purpose of this study was to examine whether personality was ...


Increasing Permanent Home Placements For Children With Diagnosed Disabilities In Foster Care, Adina Ekwerike 2018 Walden University

Increasing Permanent Home Placements For Children With Diagnosed Disabilities In Foster Care, Adina Ekwerike

Walden Dissertations and Doctoral Studies

In the United States, 397,000 children received foster care services in 2012. Some states successfully achieved permanent homes for children with diagnosed disabilities who exited care while others were less successful. Using change theory and social ecological theory as the foundations, the purpose of this study was to determine the impact that diagnosed disabilities had on permanent home placements among Pennsylvania's foster care children who were discharged and were between ages of 0 to 6 years in 2012. Hernandez's and Hodges's theory of change was used to evaluate the 1982 standards that license foster care agencies ...


Effects Of The Authentic Leadership Style On Job Satisfaction In Subordinate Employees, Theodosia Yvette Pope 2018 Walden University

Effects Of The Authentic Leadership Style On Job Satisfaction In Subordinate Employees, Theodosia Yvette Pope

Walden Dissertations and Doctoral Studies

Prior studies examined the importance of good leadership skills for those in leadership positions; however, this study addressed a gap in literature regarding how leadership characteristics in supervised employees can impact job satisfaction. The purpose of this quantitative study was to assess the influence of authentic leadership on leader, coworker, task, and general job satisfaction. Authentic leadership emerged from the theory of positive psychology which surmises that self-growth coincides with a focus on the development of others and is based on the premise that individual improvement is gained by focusing on positive personality aspects. Online recruitment using a participant pool ...


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

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 ...


Narcissistic Intolerance: Verbal Hostility And Dismissiveness In Response To Subjective Disagreement, Wan Wang 2018 Wilfrid Laurier University

Narcissistic Intolerance: Verbal Hostility And Dismissiveness In Response To Subjective Disagreement, Wan Wang

Theses and Dissertations (Comprehensive)

We examine the novel proposition that disagreement on matters of opinion may threaten narcissists’ self-esteem and cause them to express dismissiveness of differing opinions and hostility toward the dissenter, a phenomenon we refer to as narcissistic intolerance. In three studies, participants ostensibly read about an earlier participant’s opinion on a painting (Studies 1 & 2, MTurk samples) or TV show (Study 3, undergraduate sample) that agreed or disagreed with the participant’s own opinion. Participants then wrote a response to the opinion, as though they were responding on an anonymous Internet message board. We coded participants’ responses, finding that participants ...


Impressions Of A Female Political Candidate Based On Political Party Affiliation, Candice J. Veilleux 2018 University of North Florida

Impressions Of A Female Political Candidate Based On Political Party Affiliation, Candice J. Veilleux

UNF Graduate Theses and Dissertations

There is a gender gap in United States politics; men are over represented, and prioritize issues/policies differently compared with women. Stereotypes may be associated depending on group memberships. Stereotypes of men (competent) are consistent and stereotypes of women (warm) are inconsistent with politicians (competent). I examined stereotypes of major/non-major political parties, and how party affiliation affects whether stereotypes about men/male politicians/women/female politicians predict female politicians’ traits. Stereotype valence ascribed to political parties is important because people vote for a positively viewed party/representative. I assessed the strength and valence of stereotypes associated with political parties ...


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

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 ...


Influence Of Psychological Capital And Thinking Perspectives On Construction Safety Climate And Performance, Anne-Perrine Pascale Cades 2018 Walden University

Influence Of Psychological Capital And Thinking Perspectives On Construction Safety Climate And Performance, Anne-Perrine Pascale Cades

Walden Dissertations and Doctoral Studies

Understanding safety factors in construction is critical to reducing accident frequency and severity. Grounded in the safety performance model, this study was conducted to examine the impact of psychological capital (PsyCap), which consists of the shared variance of hope, efficacy, resilience and optimism, and Past, Present, and Future thinking perspectives, on safety climate and performance. A nonexperimental quantitative design was used to determine whether PsyCap and thinking perspectives of construction project employees predicted safety performance and/or moderated the relationship between safety climate and performance across construction sites in different countries. 411 construction employees were recruited via a multistage and ...


The Impacts Of Religious Discrimination Towards Anxiety In Diverse Populations, Sharlaine Marie Ortiz-Diaz 2018 Walden University

The Impacts Of Religious Discrimination Towards Anxiety In Diverse Populations, Sharlaine Marie Ortiz-Diaz

Walden Dissertations and Doctoral Studies

Previous research has indicated that outcomes of depression, anxiety, and suicidal ideation could stem from religious discrimination (RLGD). However, there remains an important gap in the current literature regarding RLGD impacts with non-Muslim populations. Further, the moderating effects of sex, race, and national origin (moderating variables [MVs]) have yielded mixed findings concerning anxiety (dependent variable). The intergroup anxiety theory and the integrated threat theory elaborate on perceived threats and potential anxiety of intergroup dynamics. The purpose of this quantitative study was to examine the role of religious preferences (independent variable), the MVs, and the RLGD-anxiety relationship. The sample consisted of ...


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

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 ...


The Relationship Between Law Enforcement Agency Size And Police Stress, William Warner 2018 Walden University

The Relationship Between Law Enforcement Agency Size And Police Stress, William Warner

Walden Dissertations and Doctoral Studies

Researchers have found that law enforcement officers often experience stress. The purpose of this quantitative study was to determine if the size of the law enforcement agency (small, medium, or large) had any significant influence on how police officers perceive stress in their profession from a cognitive appraisal perspective with regards to Administrative/Organizational Pressure, Physical/Psychological Threats, and Lack of Support. Members of law enforcement (N = 144) from Utah and New York were surveyed utilizing Spielberger et al.'s Police Stress Survey. Archival data were provided by the National Police Suicide Foundation. Stress index scores were calculated manually for ...


Black Individuals' Lived Experiences With Racial Microaggressions And Implications In Counseling, Letitia V. Browne-James 2018 Walden University

Black Individuals' Lived Experiences With Racial Microaggressions And Implications In Counseling, Letitia V. Browne-James

Walden Dissertations and Doctoral Studies

The problem of racial microaggressions in the United States has important implications for counseling due to the mental and physical health concerns individuals who experience them may develop. Although the current literature addresses racial microaggressions among Black individuals and implications for counseling, no qualitative studies that included the voices of Black individuals using relational cultural theory were found. Therefore, the purpose of this study was to explore the lived experiences of Black individuals who have encountered racial microaggressions and learn their perspectives on what counselors can do to help them in counseling. Adding this perspective will help fill this gap ...


Holistic Health And Hawaii's Renewable Energy Future, Richard M. Esterle 2018 Walden University

Holistic Health And Hawaii's Renewable Energy Future, Richard M. Esterle

Walden Dissertations and Doctoral Studies

Collective efficacy, time urgency, and health literacy have been a focus of research since the 1970s. Researchers have demonstrated that these factors influence health and decision making. However, researchers have yet to establish how these factors may be connected to the achievement of policy aims that impact holistic or environmental health. This study utilized the health belief model, social cognitive theory, time urgency theory, health education and promotion theory, Bronfenbrenner's ecological systems theory, and the Meikirch model. The purpose of this quantitative study was to determine if the factors of collective efficacy, perceived time urgency, perceived health literacy, ethnicity ...


Use Of Facebook As A Social Support System To Maintain An Individual's Resource Pool, Michelle Fontaine 2018 Walden University

Use Of Facebook As A Social Support System To Maintain An Individual's Resource Pool, Michelle Fontaine

Walden Dissertations and Doctoral Studies

Stress affects individuals' physiology, mood, behavior, and cognitive abilities. Social support has been found effective in buffering stress. The social networking site Facebook allows individuals to connect to others to share stories, pictures, and general life events and, in so doing, offers a means of social support that bridges geographical distances for friends and family. There is limited research, however, on whether using Facebook buffers against stress. The purpose of this quantitative study was to examine the use of Facebook for social support using the conservation of resources theoretical model of stress management. Fifty-seven Facebook users over the age of ...
