Psychological Determinants Of Physical Activity And The Prediction Of Physical Activity Levels In African American Men, Alvin L. Morton Iii

Doctoral Dissertations

African American (AA) men experience disproportionally higher rates of non-communicable, chronic diseases (e.g., cardiovascular, type 2 diabetes, and renal failure) than White men. Physical activity (PA) is known to reduce the progression of CVD, type 2 diabetes, and renal failure. National statistics illustrate that AA men are less likely to get sufficient levels of PA to obtain health benefits. Although many factors (e.g., biomedical, socio-cultural) influence participation in PA, the psychological factors at the individual level are essential to beginning and maintaining activity. Therefore, understanding the psychological determinants of PA in AA men and their associations with meeting national guidelines …

“If I’Ve Got God On My Side, I Can Do It”: A Phenomenological Investigation Of The Lived Experiences Of Spirituality For Lds Ncaa Di Student-Athletes, Matthew J. Moore

Doctoral Dissertations

The aim of this study was to explore the lived experiences of spirituality for National Collegiate Athletic Association (NCAA) Division I (DI) student-athletes who also identified as members of The Church of Jesus Christ of Latter-day Saints (LDS). Using an existential phenomenological approach (Thomas & Pollio, 2002), nine interviews were conducted with four self-identified female and five self-identified male members of the LDS Church who were current NCAA DI athletes at the time of the study; they participated in four different DI sports (cross-country/track and field, football, soccer, and volleyball) and attended five different DI institutions. Their mean age was …

An Evaluation Of Traffic Control Devices And Driver Distraction On Driver Behavior At Railway-Highway Grade Crossings, Radhameris A. Gomez Gabriel

Doctoral Dissertations

At-grade crossings (grade crossings) are those crossings in which any part of a roadway intersects with railroad tracks. Safety at these railroad-highway grade crossings is a major concern, with traffic control warning devices serving as the main mechanisms for improving safety. There are three factors that influence a driver’s behavior at a given crossing. First, traffic control devices, including warning devices at the railroad-highway grade crossings, provide the driver with information whose impact will depend in part on the likelihood that the driver knows whether to glance in the direction of the device based on prior experience, and in part …

Impacting Student Slumber: An Analysis Of Self-Report And Physiological Data Following A Psychoeducational Intervention, Danielle N. Newman

Doctoral Dissertations

Research shows that college students have extensive rates of sleep struggles, with up to 89% of college students reporting that they have moderate to severe difficulties with sleep (Buboltz, Brown, & Soper, 2001). Insufficient sleep has been linked to problems with academics (Kelly, Kelly, & Clanton, 2001; Taylor, Vatthauer, Bramoweth, Ruggero, & Roane, 2013), mental health (Ghumman & Barnes, 2013; Home, 1993; Manber & Chambers, 2009), physical health (Dahl & Lewin, 2002; Gailliot et al., 2007; Lyytikainen, Rahkonen, Lahelma, & Lallukka, 2011; Van Cauter, Leproult, & Plat, 2000), and a variety of other problems. Results pertaining to the suggested and …

The Development And Validation Of An Automatic-Item Generation Measure Of Cognitive Ability, Scott Hines

Doctoral Dissertations

Cognitive ability is perhaps the most studied individual difference available to researchers, being measured quickly and effectively while demonstrating a predictable influence on many life outcomes. Historically, the evolution of the psychometric study of cognitive abilities has pivoted on the development of new and better methodologies allowing for a more complete and efficient capture of intellect. For instance, recent advances in computer and Internet technology have largely replaced traditional pencil-and-paper methods, allowing for innovative item development and presentation. However, concerns regarding the potential adverse impact and test security of online measures of cognitive ability, particularly in unproctored situations, are well …

The Mediating Influence Of Career Aspirations And Career Decision-Making Self-Efficacy On Self-Differentiation, Vocational Identity, And Career Indecision, Jay Justin Middleton

Doctoral Dissertations

Research indicates that numerous family variables influence the career-development process (Osipow, 1983). Bowen's family systems theory is one model through which to view the development and influence of the family on career development (Bowen, 1972). According to his theory, individuals begin life highly dependent on family members for all forms of support. As people grow into adults, they slowly become independent of their family, or self-differentiated. Adults low in self-differentiation have been found to make decisions in order to appease their families. Further, low levels of self-differentiation have been related to greater mental health problems (Skowron & Friedlander, 1998) and …

Using Latent Class Cluster Analysis To Identify And Profile Organizational Subclimates: An Exploratory Investigation Using Safety Climate As An Exemplar, Amy Frost Stevenson

Doctoral Dissertations

Organizational climate refers to the shared meaning organizational members attach to the events, policies, practices, and procedures they experience as well as to the behaviors they see being rewarded, supported, and expected (Schneider, Ehrhart, & Macey, 2011). Climate scholars have most frequently used referent-shift consensus and dispersion composition models (Chan, 1998) to conceptualize and measure organizational climate. Based on these models, climate emergence has been characterized by low variance or high consensus of individual-level climate perceptions (Chan, 1998; Ehrhart, Schneider, & Macey, 2013; Hazy & Ashley, 2011; Kuenzi & Schminke, 2009) within formally defined organizational groups (e.g., work teams).

Climate …

Evaluating Indicators Of Job Performance: Distributions And Types Of Analyses, Richard J. Chambers Ii

Doctoral Dissertations

Distributions of job performance indicators have historically been assumed to be normally distributed (Aguinis & O'Boyle, 2014; Schmidt & Hunter, 1983; Tiffin, 1947). Generally, any evidence to the contrary has been attributed to errors in the measurement of job performance (Murphy, 2008). A few researchers have been skeptical of this assumption (Micceri, 1989; Murphy, 1999; Saal, Downey, & Lahey, 1980); yet, only recently has research demonstrated that in certain specific situations job performance is exponentially distributed (Aguinis, O'Boyle, Gonzalez-Mulé, & Joo, 2016; O'Boyle & Aguinis, 2012). To date there have been few recommendations in the Industrial-Organizational Psychology literature about how …

Anxiolytic Effects Of Propranolol And Diphenoxylate On Mice And Automated Stretch-Attend Posture Analysis, Kevin Scott Holly

Doctoral Dissertations

The prevention of social anxiety, performance anxiety, and social phobia via the combination of two generic drugs, diphenoxylate HC1 (opioid) plus atropine sulfate (anticholinergic) and propranolol HCl (beta blocker) was evaluated in mice through behavioral studies. A patent published on a September 8, 2011 by Benjamin D. Holly, US 2011/0218215 Al, prompted the research. The drug combination of diphenoxylate and atropine plus propranolol could be an immediate treatment for patients suffering from acute phobic and social anxiety disorders. Demonstrating the anxiolytic effects of the treatment on mice would validate a mouse model for neuroscientist to be used to detect the …

The Relationship Between Executive Functioning And Substance Abuse, John M. Tracy

Doctoral Dissertations

Substance use disorders are a widespread issue in society today with approximately 20 million people in the U.S. alone experiencing drug-related problems (Substance Abuse and Mental Health Services Administration, 2012). However, treatment is often ineffectual with approximately 50% of addicted individuals returning to substance use. One factor found to impact individuals' treatment response is their neuropsychological functioning. Drug-abusers frequently exhibit severe executive functioning impairments across a number of domains, and there is evidence that these deficits may be time and substance-dependent. Executive functions are mental processes critical in motivation, planning, and goal-directed behaviors. With extended abstinence, research suggests cognitive improvements …

Personal Factors, Domain Specificity, And Risky Decision-Making, Rose Niles

Doctoral Dissertations

Adults make many risky decisions daily, such as choosing to drive over the speed limit or going outside without previously applying sunscreen. How and why adults make such decisions remains relatively unknown and has gained much research attention. Traditional models of decision-making, such as Expected Utility Theory (Bernoulli, 1954) and Prospect Theory (Kahneman & Tversky, 1972) have proven too simplistic, as they do not account for the regular deviations from expected decision-making processes. Likewise, models that attempt to categorize individuals as risk seeking and risk-averse do not hold up well when decisional-domain is examined (Blais & Weber, 2006). Contemporary research …

Chronotype Preference, Partial Sleep Deprivation, And Executive Functions Performance Throughout The Wake-Cycle, Devin Layne Merritt

Doctoral Dissertations

Sleep is vital to survival and well-being. Adequate sleep, which is conceptualized in terms of quantity and quality, is positively related to a number of cognitive functions. In terms of length, it has been recommended that individuals in late adolescence and adulthood should receive no less than eight hours of sleep. Negative effects on higher-order mental processes have been found in states of sleep deprivation. Individuals who experience total sleep deprivation show decrements in performance on tasks of executive function (i.e. sustained attention, planning, and decision making). However, the effects of partial sleep deprivation on executive functions has not been …

Factors Predicting Weight Loss And Weight Gain In Bariatric Surgery Patients, Deborah Potisek Simpson

Doctoral Dissertations

Obesity has become an epidemic in the United States that can result in problems in multiple areas of an individual's life. Bariatric surgery has been shown to be an effective weight loss treatment for obese and morbidly obese individuals; however, although many individuals obtain long-term weight loss success after surgery, there is a percentage of patients who do not obtain the expected weight loss or end up regaining the weight they had initially lost. In an attempt to identify those who may be at risk for poorer results after bariatric surgery, most surgeons require that an individual undergo a psychological …

Ptsd, Academic Achievement, And College Persistence: The Moderating Effects Of Coping Mechanisms And Social Support, Rebecca Granda

Doctoral Dissertations

Prevalence rates of lifetime exposure to trauma for college students range from 50 to 90% indicating that most college students begin the first year of college with a history of trauma. Previous studies suggest a significant negative relationship between posttraumatic stress disorder (PTSD) and college retention; however, these studies have mainly focused on the negative effects of trauma exposure and PTSD on college students' persistence. As a result, it was unknown whether the effects of PTSD on academic achievement and college persistence can be moderated by protective factors, such as coping skills and social support. The purpose of this study …

May I Help You? How Stereotypes And Innuendoes Influence Service Encounters, Lauren Michelle Brewer

Doctoral Dissertations

"You only get one chance to make a good first impression." The dissertation focuses on marketing agents; among the most visible is the "service provider." Previous research establishes the important role of cognitive social schemata in determining the way consumers react to different types of marketing agents, including service providers. In the literature review, a classification schema is developed for service provider stereotypes derived from theory using social stereotypes. The development of the Service Provider Perception Framework (SPPF) creates a classification for the individual service provider along two main dimensions: competence and affect.

In services design (particularly situations involving a …

An Examination Of The Effectiveness Of The Louisiana Gear Up Program In Promoting Self-Efficacy, Improving Academic Achievement And Increasing Teachers' Aspirations For Their Students, Candi Hill

Doctoral Dissertations

Students are likely to avoid academic pursuits if they lack academic self-efficacy (Bandura, 2000). Furthermore, past poor academic performance contributes to the development of low academic self-efficacy. Students who participate in extracurricular activities, like LA GEAR UP, demonstrate better academic achievement and less risk-taking behaviors than non-participating students (Barber, Stone, & Hunt, 2003). Research supports the notion that LA GEAR UP is an effective way to improve students' academic performance and to reduce the number of disciplinary referrals students receive (Beer, 2009). Additionally, within the academic literature research has demonstrated that teachers' attributions about students are based upon their perceptions …

Racial Prejudice, Homophobia, And Sexism As A Function Of Right-Wing Authoritarianism, Religious Values, Religious Pressures, And Religious Orientation, Dixie Turner

Doctoral Dissertations

Past literature is ambiguous regarding relationships among different religious variables and prejudice. The purpose of this study was to clarify complicated relationships among religious pressures, religious fundamentalism, Christian orthodoxy, intrinsic and extrinsic religious orientation, quest orientation, right-wing authoritarianism, and the outcome variables of racial prejudice, homophobia, and sexism. Two models, a developmental model and social learning model, were proposed in this study and were tested using structural-equation modeling. Participants were 310 self-identified Christian students. Several predicted paths were deleted in both models because they did not contribute to good fit. Three predictor variables: Christian orthodoxy, extrinsic religious orientation, and religious …

“It Can Start From Anything”: An Existential Phenomenological Investigation Of Athletes’ Experiences Of Psychological Momentum, Greg Young

Doctoral Dissertations

Psychological Momentum (PM) is a commonly recognized phenomenon in sport, yet remains one of the least understood (Taylor & Demick, 1994). Previous research examined PM using archival data (Gayton & Very, 1993; Gilovich, Vallone, & Tversky, 1985; Koehler & Conley, 2003; Silva, Hardy, & Crace, 1988), hypothetical and contrived scenarios (Eisler & Spink, 1998; Miller & Weinberg, 1991; Perreault, Vallerand, Montgomery, & Provencher, 1998; Vallerand, Colavecchio, & Pelletier, 1988), and actual performance (Mack, et al., 2008). More recently, Jones and Harwood (2008) used semi-structured interviews to examine participants’ …

An Exploration Of The Relationship Among Online Social Network Usage, Intimacy, Social Comparison Tendencies, And Relationship Satisfaction, Matthew Hand

Doctoral Dissertations

The popularity of online social networks prompts an examination of the effects these websites have on intimate relationships. While these networks have received a considerable amount of attention in mainstream media, peer-reviewed research examining the effects these websites have on users is sparse. By their very nature, online social networks involve the creation and maintenance of interpersonal relationships. As such, the effect of these networks on relationships may be profound and with the paucity of research on the topic, the relationship between online social networks and interpersonal relationships is an important area of study. The present study sought to examine …

Selected Demographic Characteristics And Social Interest As Predictors Of Teacher Stress, Barry J. Morales

Doctoral Dissertations

The purpose of the research was to study stress in teachers in Louisiana by utilizing a descriptive/comparative research design. Hypotheses were tested concerning relationships between each of seven independent variables and the dependent variable (teacher stress). The independent variables were (a) years of teaching experience, (b) educational levels of teachers (college degrees), (c) age, (d) gender, (e) social interest, (f) geographical location (North and South Louisiana), and (g) educational levels of students taught by teachers (elementary, middle, high school). The procedure for choosing the participants involved a sample of convenience whereby superintendents provided access/permission to specific schools. Nine schools (three …

Weight Gain Among Adults With Intellectual Disabilities Receiving Atypical Antipsychotics, Sherri Lyn Transier

Doctoral Dissertations

The present study assessed whether the atypical antipsychotic agents olanzapine, risperidone, and quetiapine are associated with significant weight gain among adults with intellectual disabilities after 6 months of drug treatment. The body weights of 79 participants were retrieved 6 months prior to the initiation of drug treatment, at the start of the atypical antipsychotic agent, and after 6 months of drug therapy. Each individual served as his or her own control by utilizing pretreatment baseline trends in weight change to calculate a dependent measure of adjusted posttreatment weight gain. Doing so allowed for a stringent determination of the liability for …

Detection Of Malingering Via Cognitive Cues, Birgit M. Smart

Doctoral Dissertations

Malingering is a frequently encountered problem of faking psychological or physiological symptoms or exaggerating existing conditions for external gain. Malingerers typically are seen in clinical and forensic settings and create a burden to our society due to loss of economic resources or professional time. The impact of malingering is difficult to calculate due to problems with identifying actual cases of malingering. Psychological tests traditionally have been used in the assessment of malingering. Despite major improvements in instruments and clinical interviewing techniques, however, no failsafe assessment tool has been identified for the accurate detection of malingering. Cognitive studies of lie detection …

Proactive Behavior: A Selection Perspective, Laura Elizabeth Marler

Doctoral Dissertations

In the 15 years since Bateman and Crant (1993) formulated the construct of proactive personality, numerous researchers have devoted a significant amount of attention to proactive attributes and behaviors (e.g., Parker, Williams, & Turner, 2006; Crant, 2000; Frese & Fay, 2001; Parker, 2000; Erdogan & Bauer, 2005). Campbell's (1990) model of performance suggests that an organization's selection system may ultimately promote proactive behavior. Consequently, in this dissertation, I advocate a selection approach as the initial building block towards creating a workplace in which proactive behavior is a fundamental outcome.

One of the selection tools yet to be explored by researchers …

An Exploration Into Gender Role Conflict, Attitudes Toward Females, And Relationship Beliefs, Julia M. Wood

Doctoral Dissertations

Gender role conflict and negative attitudes toward females have been areas of increasing concern since the early 1970s. Research has shown that both gender role conflict and negative attitudes toward females cause complications for the person with such perspectives. Relationships are an area that has been impacted by gender role conflict and attitudes toward females. Determining the impact that gender role conflict and attitudes toward females have upon each other and upon relationship beliefs will increase awareness of the seriousness of these complications allowing clinicians to focus therapeutic interventions on methods that will increase relationship quality.

Using the Gender Role …

An Investigation Of The Relationship Among Life-Skills, Self-Esteem, And Well-Being In Adults, Scott David Meche

Doctoral Dissertations

This study examined the relationship among life-skills, self-esteem, and well-being in 278 adults. Adults were classified into three age groups. Of the 278 participants, 96 were young adults, 92 were middle-aged, and 90 were older adults. Life-skills, global organizations of general coping skills that are learned behaviors which enable effective functioning, were assessed with the Life-Skills Inventory - Adult Form (Gazda, Illovsky, & Taylor, 1991). Analyses were performed to understand the influence of four generic life-skills areas, interpersonal communication/human relations, problem-solving/decision making, identity development/purpose in life, and physical fitness/health maintenance, on self-esteem. Self-esteem was measured with the Self-Esteem Inventory-Adult Form …

Postural Balance And Acceleration Threshold Detection For Anterior Horizontal Translation In Diabetic And Non-Diabetic Elderly, Venkatesh Balasubramanian

Doctoral Dissertations

Slips and falls, and even the fear of failing, can represent a major medical and functional deterrent to living independently, especially among the elderly population. Various groups of elders are at known risk for falling including, but not limited to, those with vestibular dysfunction, those with low visual acuity including visual neuropathies, and those with peripheral neuropathies. The first two groups are fairly well studied, but the relationship between the level of peripheral neuropathy and extent of falling has received relatively less attention.

In this study, using sliding linear investigative platform for analyzing lower limb stability (SLIP-FALLS), the psychophysical thresholds …

Religious Involvement And Dispositional Characteristics As Predictors Of Work Attitudes And Behaviors, Tami Leigh Knotts

Doctoral Dissertations

The purpose of this dissertation was to empirically examine the effects of (1) religious involvement on job attitudes, (2) dispositions on job attitudes, and (3) religious involvement on workplace behaviors. This study also assessed whether job attitudes mediated the effect of religious involvement an workplace behaviors or the interaction effect of religious involvement and dispositional characteristics on workplace behaviors.

Higher levels of religious involvement were hypothesized to lead to more positive work attitudes and behaviors. Conservative and self-transcendent values along with positive well-being were expected to lead to positive attitudes at work. The effect of religious involvement on work behaviors …

A Social-Cognitive Approach To Salesperson Work Motivation, Lawrence Scott Silver

Doctoral Dissertations

The purpose of this study was to apply a social-cognitive model of motivation, used extensively in educational psychology, to a sales setting. The topic pertaining to work motivation and its importance is evidenced by the amount of research devoted to the topic. The literature examined for this study was selected from the fields of industrial/organizational psychology, educational psychology, and marketing/sales. Specifically, this study addressed the following research questions: (1) To what extent is salespeople's goal orientation determined by their implicit personality theory? (2) Do salespeople's goal orientation determine their behavior pattern? (3) Does optimism moderate the relationship between salespeople's implicit …

An Empirical Examination Of Individual, Issue-Related, And Organizational Determinants Of Ethical Judgments, Sean Robert Valentine

Doctoral Dissertations

The purpose of this dissertation was to empirically examine an ethical decision-making model that contained individual, issue-related, and organizational factors. At the individual level, the relationship between two job attitudes, job satisfaction and organizational commitment, and ethical judgments was assessed. At the issue-related level, the association between moral intensity and ethical judgments was examined. At the organizational level, the relationship between ethical context and ethical judgments was examined. The hypothesized moderating effect of ethical context on the relationship between job attitudes and ethical judgments was also tested.

A national sample of 3,000 sales professionals was used to test the hypotheses. …

The Use Of Prior Knowledge In Learning From Examples, Stephen B. Blessing '89

Doctoral Dissertations

This dissertation examines the way people acquire procedures from examples, and provides a computational model of the results. In four experiments, people learned an analog of algebra. For each experiment, the initial know ledge that people had of the task was varied. In two experiments (Experiments 1 and 3), the syntactic know ledge that people had concerning the task w as manipulated. The knowledge of syntax that participants had, particularly the ability to correctly parse the character string, was found to be a major determiner in the way participants acquired the rules. Experiment 2 explicitly manipulated participant's awareness as to …
