Authoritarianism, Hostility Toward Women, Attitudes Toward Violence, Rape Myth Acceptance, And Sexual Aggression, Gina M. Bondi

Psychology Theses & Dissertations

Almost one out of every five women has been, or will have been, the victim of sexual aggression and/or rape in their lives (National Institute of Justice, 2000). This staggering statistic exemplifies the importance of speculating which traits are related to, or are predictive of, sexually aggressive behavior. Based on previous research, the current study investigated relationships between authoritarianism, hostility toward women, attitudes toward violence, and rape myth acceptance, as related sexual aggression in undergraduate men It was projected that authoritarianism, hostility toward women, attitudes toward violence, and rape myth acceptance would significantly and positively predict all dimensions of sexual …

Methods Of Detecting Differential Item Functioning: A Comparison Of Confirmatory Factor Analysis Methods, Jenny Chia Yi Kuang

Psychology Theses & Dissertations

The present Monte Carlo study compared four confirmatory factor analysis (CFA) methods for detecting differential item functioning (DIF). The four methods were the noniterative and iterative mean and covariance structure analysis (MACS) methods, the modification index (MI) method, and the modification index-divided sample (MI-divided) method. Reference and focal groups responded to 12 items with 3 of the 12 items designed to exhibit DIF. Sample sizes of 250 and 500 were examined. In addition, three types of DIF were examined: DIF on loadings, DIF on thresholds, and DIF on both loadings and thresholds. Results indicated that for sample size 250, all …

An Identity Approach To Understanding Diversity, Inclusion And The Work-Family Interface, Rebekah A. Cardenas

Psychology Theses & Dissertations

The salience of one's ethnic identity, the subjective importance of that identity in one's life, was hypothesized to impact the extent to which inclusion predicts work-related outcomes (i.e., strain-based work-family conflict, work-family enrichment, job satisfaction and job stress) among 225 working women. Women who felt included at work (i.e., those who can participate, have influence and can "be themselves") were predicted to experience positive work-related outcomes. Further, belongingness at work was predicted to interact with ethnic identity salience to impact work-related outcomes for working women. Hierarchical linear regression analyses indicated that inclusion was significantly associated with positive work-related outcomes; yet, …

Fatigue's Influence On Workload, Situation Awareness, And Performance In A Military Simulation Of Combat, Carlotta M. Boone

Psychology Theses & Dissertations

Military operations routinely require military personnel to consistently perform their duties over several hours or days. Tasks that require prolonged work can lead to mental fatigue and decreased performance. The transactional model proposes that individuals cope with changes in the environment and maintain performance. This ability to cope is determined by factors of the environment and the individual's personality. One environmental factor that can influence coping is extended task performance. This study examined the effect of extended task performance and its interaction with task difficulty. Participants interacted with the military simulation game Command and Conquer: Generals™ for three hours. They …

Teamwork In Chinese Organizations: A New Concept And Framework, Ying Liu

Psychology Theses & Dissertations

Teamwork has always been a challenge in China, and the importance of teamwork has not been well recognized. This study was designed to explore the underlying definition of teamwork that Chinese people use to describe their teams, to identify variables related to teamwork, to develop a new framework and measure of teamwork in Chinese organizations, and to test the psychometric properties of the measure as well as the structural relationships of the new framework of teamwork in Chinese teams. This study also examines the influence of guanxi---an important Chinese cultural value that emphasizes exchange and reciprocity in relationships---on teamwork in …

Teacher Factors That Influence Student Achievement: A Study Of Third And Fifth Grade Teachers, Jewelle L. Harmon

Psychology Theses & Dissertations

Student achievement is of the highest concern for the government, educational administrators and parents. Researchers have looked at several possible student factors that affect student achievement. However, very little research has been done on teacher factors and their relationship with student achievement. The current study looked at the relationships among teacher absence, teacher job satisfaction, work-family conflict, family/work conflict, teachers' attitudes towards achievement measures, and their correlation with Virginia's standardized measure of student achievement; the Standards of Learning (SOLs). District differences in student achievement were also examined. Three school districts in southeastern Virginia accepted the invitation to participate. …

Self-Reported Attitudes, Concerns, And Behaviors Related To Global Environmentalism: Can A Mandatory Class Make A Difference?, Erin Mehalic

Psychology Theses & Dissertations

The purpose of the study was to determine what initial attitudes and behaviors first-year college students had about the environment and how they changed as a result of a taking a required global environmentalism course. A second goal in this study was to learn whether there were differences in environmental attitudes and behaviors based on gender and ethnicity. Participants in this study were first-year students at Old Dominion University enrolled in a mandatory general education course, New Portals to Appreciating the Global Environment ( GEN 101 ). An online survey was completed that measured the participants' attitudes and behaviors related …

A Structural Model Of Relationships Between Employee Characteristics, Supervisory Mentoring Behaviors And Job Satisfaction, Florence R. Jinadu

Psychology Theses & Dissertations

Organizational researchers have consistently found that developmental mentoring has a positive effect on employees professional and career success. Some of the benefits that have been cited include increased job satisfaction, increased organizational commitment, and increased self-esteem among mentored employees. In addition to these short-term benefits, developmental mentoring has also been found to positively impact long-term career outcomes in the form of increased compensation and career mobility for mentored employees as compared to non-mentored employees. Traditionally, mentors have been described as influential senior members of an organization who provide career support and developmental opportunities to less experienced employees, who are referred …

Understanding The Nature Of Surgical Excellence Using A Competency Modeling Approach, Hope S. Hanner-Bailey

Psychology Theses & Dissertations

Currently, a thorough description of the knowledge, skills, abilities, and other personal characteristics (KSAOs) that distinguish an exceptional surgeon does not exist. This knowledge is pertinent to the development of selection, training, and performance assessment methods that can be used to develop high performing surgeons. Expert surgeons from around the country were recruited to participate in an interview to discuss the KSAOs (i.e., the competencies) needed to be exceptional in the field. A smaller number of novice surgeons were also interviewed. The expert interview data were distilled into a competency model that consists of ten competencies and patterns within the …

Corporal Punishment And Its Relation To Race, Psychological Well-Being, And Parental Relationship, Michelle P. Kravitz

Psychology Theses & Dissertations

Previous research has documented the numerous negative effects associated with corporal punishment (Gershoff, 2002). The present study examined whether experiencing corporal punishment as a child is related to one's perception of the legitimacy of corporal punishment, race, the nature of the parent-child relationship (i.e., biological parent versus step-parent), and psychological well-being. Compared to college students who did not experience corporal punishment during childhood, college students who experienced higher levels of corporal punishment are expected to report that corporal punishment is a more acceptable form of discipline. College students who grew up with a stepfather were expected to be more likely …

What Is Positive Disclosure And To Whom Do We Disclose? The Role Of Topics, Gender And Type Of Relationship In Positive Self-Disclosure, Elizabeth Landers Ford

Psychology Theses & Dissertations

This study examined what topics (including experiences, feelings, and thoughts) people define as positive self-disclosure. The study also looked at reasons people generate for self-disclosing versus not disclosing something positive. Male and female students spontaneously described a past experience or feeling they perceive to be personal and positive. They then indicated whether or not they disclosed about these experiences or feelings to their father, mother, same-sex friend, and a past or present significant other/spouse. These descriptions were coded into one of eight categories: Religion, Family Development, Friendship, Sex, Romance, Self-Confidence, Achievement, and Helping Behavior, plus a Miscellaneous category. There were …

The Effects Of Parcels And Latent Variable Scores On The Detection Of Interactions In Structural Equation Modeling, Thomas D. Fletcher

Psychology Theses & Dissertations

Numerous theories in the behavioral and organizational sciences involve the regression of an outcome variable on component terms and their product to evaluate interaction effects. There are numerous statistical difficulties with this multiple regression approach. The most serious is measurement error, requiring the use of structural equation modeling. Jöreskog and Yang (1996) described a nonlinear structural equation modeling procedure that incorporates mean structures in the covariance analysis. They demonstrated that only one indicator for the product term is necessary for model identification. Unfortunately, the Jöreskog-Yang procedure leads to biased estimates of the product coefficient. In this dissertation, I propose that …

Pilot Performance And Eye Movement Activity With Varying Levels Of Display Integration In A Synthetic Vision Cockpit, Julie Michele Stark

Psychology Theses & Dissertations

The primary goal of the present study was to investigate the effects of display integration in a simulated commercial aircraft cockpit equipped with a synthetic vision display. Combinations of display integration level (low/high), display view (synthetic vision view/traditional display), and workload (low/high) were presented to each participant. Sixteen commercial pilots flew multiple approaches under IMC conditions in a moderate fidelity fixed-base part-task simulator. Pilot performance data, visual activity, mental workload, and self-report situation awareness were measured.

Congruent with the Proximity Compatibility Principle, the more integrated display facilitated superior performance on integrative tasks (lateral and vertical path maintenance), whereas a less …

Creating Individual Behavior Change Through 360-Degree Feedback: A Development Pipeline Perspective, Victoria Cole Stage

Psychology Theses & Dissertations

Ensuring that individuals develop new and more productive behaviors on the job is a challenge for many organizations and a focus of time, effort, and energy spent on programs to facilitate this change. This research was an effort to validate and utilize a framework for understanding how efforts toward individual development are restricted. To do this, I used a new 360-degree feedback instrument called “Time 2 Change” that measures self, manager, direct report, and peer/colleague perceptions of change in the individual. This instrument also measures the individual's perceptions of development enablers, in a framework called a Development Pipeline. As a …

Crisp And Fuzzy Signal Detection Theory And Pilot Weather Judgment: Implications For Vfr Flights Into Imc, Joseph T. Coyne

Psychology Theses & Dissertations

Weather represents one of the greatest hazards to general aviation (GA), accounting for 15% of the GA accident fatalities. Of the fatal weather accidents 90% are attributed to visual flight rules (VFR) flight into instrument meteorological conditions (IMC). The situation assessment hypothesis suggests that pilots may inadvertently enter IMC because they lack the sensitivity needed to distinguish between visual meteorological conditions (VMC) and IMC. An alternative hypothesis is that pilots recognize conditions have deteriorated but are motivated by some other factor, such as pressure from passengers. The present study uses Jensen's Pilot Judgment Model and Signal Detection Theory to explain …

Acknowledgement Response And Interference Timing During The Processing Of Voice And Datalink Atc Commands, Matthew R. Risser

Psychology Theses & Dissertations

In aviation, effective communication between air traffic control (ATC) and pilots is critical to pilot performance and safety. Problems and limitations of current radio communications initiated the development of datalink technology. Datalink is a text system used to send messages between ATC and pilots. Although datalink was intended to reduce errors associated with radio communication, there are new concerns related to changes in information processing demands associated with executing speech and text ATC commands. In addition, the nature of responses differs between voice and datalink systems. In a voice environment, responses are immediate. However, time delays exist with datalink. These …

The Effects Of Operator Trust, Complacency Potential, And Task Complexity On Monitoring A Highly Reliable Automated System, Nathan R. Bailey

Psychology Theses & Dissertations

Technological advances have allowed for widespread implementation of automation in complex systems. However, the increase in quantity and complexity of advanced automated systems has raised a number of potential concerns including degraded monitoring skills. The present investigation consisted of two studies that assessed the impact of system reliability, complacency potential, monitoring complexity, operator trust, and system experience on monitoring performance. In both studies, participants monitored a simulated aviation display for failures while operating a manually controlled flight task. In addition, the second experiment assessed the ability of operators to detect a single automation failure over three experimental sessions. Results indicated …

The Psychological Contract Of Multiple Agency Relationships: Understanding The Attitudes And Behaviors Of Contractors, Cynthia J. Maahs

Psychology Theses & Dissertations

Previous research offers inconsistent findings with respect to attitude and behavior differences for contingent and permanent workers. The current study proposes the psychological contract as an explanatory framework for understanding differences between contractors and regular employees. The hypotheses examined attitudinal and behavioral measures: organizational commitment, job satisfaction, intent to quit, job performance, and organizational citizenship behaviors. The two components of the psychological contract (relational vs. transactional) were thought to impact differentially the outcome measures. Approximately 650 employees in a technology contracting organization completed an on-line survey designed to test the hypotheses. The two-factor structure of psychological contract was confirmed and …

The Relationship Among Disclosure, Internalized Homophobia, Religiosity, And Psychological Well-Being In A Lesbian Population, Sharon Lyn Clayman

Psychology Theses & Dissertations

This study investigated the relationship among disclosure, internalized homophobia, and religiosity in a lesbian population and how these three variables are related to psychological well-being in order to build upon the scant amount of empirical research on these variables in the lesbian psychological literature. A total of 679 women, 18 to 70 years old, and from all across the country were recruited via the internet to participate in a web-based survey. Participants completed a demographic questionnaire, the Lesbian Internalized Homophobia Scale (Szymanski & Chung, 2001), the Outness Inventory (Mohr & Fassinger, 2000), the Behavioral Self-Disclosure Questionnaire (Carroll & Gilroy, 2000), …

Comparisons Among Parent Reports And Self-Reports Of Sleep In Adhd And Normal School-Aged Children, Diana M. Turner-Eadie

Psychology Theses & Dissertations

The objective of the study was to investigate whether school-aged children diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD) experience greater sleep disturbance than do normally-developing children. Participants included 33 parents and their children with ADHD (mean age = 10.7 ± 1.7 years) and 33 parents and their children without ADHD (mean age = 10.7 ± 1.6 years). Both parents and their children completed sleep questionnaires developed to assess a number of sleep variables. Based on parental report, the Total Sleep Disturbance score was significantly greater for the ADHD group than for the comparison group. Parents indicated that children with ADHD had …

Identifying The Dimensions Of Integrity: A Confirmatory And Discriminant Validity Analysis, Arlene Pace Green

Psychology Theses & Dissertations

While Integrity tests have demonstrated significant predictive and concurrent validity, the meaning and structure of integrity test scores are not well understood. The purpose of the present investigation was to empirically verify the results of a previous study that used an inductive method to define integrity and identify its constituent dimensions (Green, 1999). Specifically, the present investigation used item analysis, confirmatory factor analysis, discriminant validity analysis, and an analysis of social desirability to test the validity of the five integrity dimensions identified by Green (1999): Concern for Others, Conscientiousness, Emotional Control, Fairness, and Honesty. Results confirmed that Integrity acts as …

The Relationship Of Mmpi-A Item Effectiveness To Item Content, Diagnostic Category, And Classification Accuracy, Kathleen D. Lynch

Psychology Theses & Dissertations

Archer, Handel, and Lynch (2001) recently compared the item endorsement frequencies for the MMPI-A normative sample against two adolescent clinical samples. Results showed that the MMPI-A contains a substantial number of items that do not show a significant difference in item endorsement frequency between normative and clinical samples. The current study extends Archer et al.'s (2001) research in three ways: (1) it examines the item endorsement frequencies of the Supplementary scales, Harris Lingoes subscales, and subtle-obvious items; (2) it examines the Basic, Content, and Supplementary scales, and Harris Lingoes subscales with two homogeneous diagnostic criterion groups (as suggested by Archer, …

An Examination Of Personality As A Predictor Of Guard Behavior In A Virtual Environment, Jean M. Catanzaro

Psychology Theses & Dissertations

Military personnel need access to realistic training tools that can provide a safe environment in which to acquire skills that will generalize to real world tasks. A virtual environment (VE) is one such tool. The focus of the present study was to evaluate a VE as a training tool for military guards. The first goal was to examine the potential of VE technology to provide effective training for standing watch at a military checkpoint. The second goal was to study a set of personality traits that might predict performance. Participants completed the NEO Personality Inventory and were trained to perform …

Proactive Personality And The Big Five As Predictors Of Motivation To Learn, Jonathan E. Turner

Psychology Theses & Dissertations

In an environment of changing psychological contracts, corporate downsizing, and increases in alternative self-paced training delivery channels, motivation to learn is believed to represent a key variable in employee self-development that distinguishes employees who will thrive from those who will not. Predicting this variable, then, becomes an important step in managing workforce development and helping employees help themselves. Therefore, the efficacy of relevant personality characteristics as predictors of motivation to learn was investigated. Proactive personality and the Big Five factors of personality were hypothesized to be predictive of motivation to learn. These personality variables are relevant because they have been …

The Contribution Of Enactments To Structural Family Therapy: A Process Study, Stephanie Fellenberg

Psychology Theses & Dissertations

In an era where the effectiveness of many forms of psychotherapy has been thoroughly examined, the focus of many researchers has shifted from investigating outcome to exploring therapeutic processes. Process studies serve to identify the active ingredients of therapy—that is, those interventions that bring about in-session changes. This process study examines the relationship between the use of enactments, a structural family therapy intervention, and in-session change as observed over the course of the session. Change was measured by the amount of change that occurred in the core problem dynamic, that is, the most prominent pattern of dysfunctional family …

The Role Of Alexithymia In Ethnic Groups On Eating-Related Attitudes And Behaviors, Lisa M. Newman

Psychology Theses & Dissertations

Alexithymia, a term referring to deficits in ability to describe and differentiate emotions, has been studied in a variety of Caucasian medical and psychiatric populations, including patients with eating disorders. Research suggests that alexithymia is more prevalent among the Caucasian eating disordered population than the general population. However, there is little research on the prevalence of alexithymia or its relationship to problematic eating-related attitudes and behaviors in African Americans. This study investigated and compared the occurrence of alexithymia and its effects on eating-related attitudes and behaviors in Caucasian and African American college women using the Toronto Alexithymia Scale-20 and the …

Examining The Equivalence Of Rater Groups In 360-Degree Feedback For Use In Leadership Development, Amy Fitzgibbons

Psychology Theses & Dissertations

This study assessed the seldom-considered aspect of measurement equivalence across the three most common rater groups in 360-degree feedback systems. The graded response model for polytomous items was used to assess differential functioning of items and tests and applied to an archival data set of 664 ratees to determine the equivalence of peer, subordinate, and supervisor ratings of four leadership competencies. The results indicate that the leadership competencies were invariant across the three rater groups. The results and conclusions produced are discussed with practical implications in mind.

Time-Based Work-Family Conflict: Myth Or Reality?, Karyn H. Bernas

Psychology Theses & Dissertations

The present study examined a time-based model of work-family conflict for a sample of 176 working women with childcare responsibilities. Building on the work of Edwards and Rothbard (2000) and role theory, a model was proposed to test the specific variables that define time-based work-family conflict. Hierarchical regression analyses were used to test the proposed hypotheses. Contrary to assumptions about time-based conflict, the results suggest that role time has a very limited impact on work-family conflict. Variables that were related to role performance and satisfaction included traditional gender role expectations, family involvement, family instrumental support, leader-member exchange, role overload, and …

Creating Inclusive Organizations: Its Meaning And Measurement, Bryan Christopher Hayes

Psychology Theses & Dissertations

There is growing interest in the concept of inclusion by both scientists and practitioners. The goal of the current study was to bring empirical support to the organizational inclusion literature. Inclusion was defined as a psychosocial need and a model was developed specifying its relationship to antecedent and consequence variables. The measurement model was explored with a sample of responses from 418 undergraduate students (Study 1). The measurement model was confirmed and the structural model was assessed with a sample of responses from 609 employees of a medical center (Study 2). Results of structural equation modeling provided limited support for …
