Changes In Cerebral White Matter, Vascular Risk And Cognition Across The Adult Lifespan, Andrew Robert Bender

Wayne State University Dissertations

Numerous studies over the past decade have used diffusion tensor imaging (DTI) to examine associations between age, diffusion and anisotropy measures of cerebral white matter (WM), and cognitive performance. However, few have examined relationships between intra-individual change in DTI measures of WM and cognitive function. It is possible that the extant cross-sectional findings are a poor representation of age-related change in WM and cognition. The present study used latent difference-score modeling (LDM) to assess change over two years in DTI indices fractional anisotropy (FA), radial diffusivity (DR), axial diffusivity (DA) and mean diffusivity (MD). In addition, we examined the effects …

Religiosity-Spirituality And Risky Drinking Over The Transition To College: A Multi-Wave Longitudinal Study, Brian J. Klassen

Wayne State University Dissertations

Although the relationship between religiosity-spirituality and risky alcohol use is one of the most frequently studied topics in mental health, relatively little is known about how these variables relate to each other over time, especially during specific developmental periods such as the transition from high school to college. This study analyzed three waves of self-report data collected from a sample (N=623) of college students over a two-year period. Analyses examined (1) the stability of religiosity-spirituality and risky drinking over the transition to college, (2) the magnitude and direction of relationships between religiosity-spirituality and risky drinking, (3) the degree to which …

Self-Construal Moderates Testosterone Reactivity To Competitive Outcomes, Keith Welker

Wayne State University Dissertations

Previous research shows that testosterone reactivity to competitive outcomes predicts aggressive behavior in men. However, some studies have failed to find these effects, and it has been suggested that individual differences moderate the relationships between competitive outcomes, testosterone fluctuations, and aggressive behavior. The current research examined whether one individual difference--self-construal--would moderate these effects. In Study 1, participants were assigned to win or lose a competitive video game and engaged in a reactive aggression task. Results indicated that increases in testosterone in response to winning and decreases in response to losing occurred in men with independent, not interdependent, self-construals. These changes …

The Reliability And Validity Of The Thin Slice Technique: Observational Research On Video Recorded Medical Interactions, Tanina Suzanne Foster

Wayne State University Dissertations

The Reliability and Validity of the Thin Slice Technique: Observational Research on Video Recorded Medical Interactions

Introduction: Observational research using the thin slice technique has been routinely incorporated in observational research methods, however there is limited evidence supporting use of this technique compared to full interaction coding. The purpose of this study was to determine if this technique could be reliability coded, if ratings are consistent between the first, second and third slice, and if they are indeed representative of full interactions.

Methods: Three 30-second thin slices were sampled from the beginning, middle and end of a full-length video-recorded …

The Effects Of A Career-Planning Course On Community College Students' Career Self-Efficacy And Career Indecisiveness, Jefferey Samuel Lip

Wayne State University Dissertations

The principal aim of this study was to evaluate the effectiveness of a career-planning course for college students who were undecided on a major or want to change or confirm their major at community college. The career-planning course was designed to assist students in becoming more aware of themselves and career options. From this study, the career-planning course assisted students in improving their career decision-making self-efficacy. A reduction in career decision-making difficulties for students was seen in this study. A quasi-experimental nonequivalent control group research design was used for this study. To determine if the experimental and control group were …

Employee Pronoun Use In Verbatim Comments As A Predictor Of Job Attitudes And Turnover Intentions, Amy E. Sund

Wayne State University Dissertations

It is common in employee attitude surveys to collect open ended comments from employees, yet this data remains largely under-utilized. In the present study, it is hypothesized that employee pronoun use is related to job attitudes and turnover intentions, such that the use of "we" type pronouns is higher among more satisfied employees; and that the use of "non-we" type pronouns is higher among less satisfied employees. Results largely did not support hypotheses - although "non-we" use was negative related to job attitudes, "we" use was also negative related. It is believed that the reason for the lack of findings …

Empathy As A Moderator Of Adolescent Bullying Behavior And Moral Disengagement After Controlling For Social Desirability, Amy Zelidman

Wayne State University Dissertations

The purpose of this study was to assess the moderating influence empathy has on the associations between adolescent bullying behavior and moral disengagement after controlling for social desirability (e.g., response bias). 676 students in 7th and 8th grade from a suburban middle school in Southeast Michigan participated in this study in the fall of 2012.

Results showed male respondents were more likely than female respondents to (a) report engaging in all forms of traditional bullying behavior overall, including physical, verbal, and social bullying and (b) report higher rates of physical victimization and moral disengagement. Female respondents were more likely to …

Understanding The Role Of Nutritional Stress In The Adult And Developing Zebra Finch, Jessica Bayley Thompson

Wayne State University Dissertations

Songbirds are particularly susceptible to stress during the sensitive period for song learning. Thus the developmental stress hypothesis (DSH) proposes that adult song reflects a male's early life environment during this period. Nutritional stress (NS) has been shown to cause deficits in song learning and adult song output that are salient to females. Female song birds consistently prefer control males over those raised under NS, yet the effects NS on females are still unclear. The hypothalamic-pituitary-adrenal axis (HPA) has been implicated in this process. However, evidence directly linking HPA functioning to the deficits due to NS have inconsistently shown elevations …

Does The Leader Fit The Place? Examining Leader-Culture Fit And Its Implications For Leader Effectiveness, Benjamin John Biermeier-Hanson

Wayne State University Dissertations

The present study focused on a relatively new concept, Leader-Culture Fit (L-C Fit), to help bridge the empirical gap that exists between the literatures on leadership and organizational culture. L-C Fit, a subtype of Person-Environment fit, was examined here by testing the complex relationships between perceptions of leaders, perceptions of their cultures, and how the fit between the two relates to leader effectiveness. The present study found that fit (and misfit) between a leader and their culture for perceived leader effectiveness. Specifically, fit is beneficial for perceived leader effectiveness when the leader and the culture are in alignment and are …

Identifying And Understanding Nonsuicidal Self-Injury Among College Students, Angela S. Fedewa

Wayne State University Dissertations

Nonsuicidal self-injury (NSSI) behavior in college students

at an urban university was studied. Relations between NSSI

and poor quality relationships with their parents and peers, as

well as deficient coping and help-seeking behavior were examined

from an attachment perspective. Undergraduates were recruited

via an online psychology subject pool and completed an online survey.

T-tests were conducted to identify what variables differed between

students who engaged in NSSI in contrast to students that did not.

In addition, a discriminant function analysis was conducted. It was

found that intrapersonal and interpersonal variables predicted group

membership (i.e. social desirability, body protection, positive affect, …

A Daily Study Of The Sleep-Pain Relationship In Fibromyalgia, Maren Elizabeth Hyde-Nolan

Wayne State University Dissertations

Fibromyalgia (FM) impacts millions of individuals around the world and is characterized by widespread chronic pain and tenderness as well as nonrestorative sleep, fatigue, and stiffness (Wolfe et al., 1990; Wolfe et al., 2010). Poor sleep quality is reported by more than 90% of individuals with FM, suggesting that sleep disturbance may be a contributing factor to the pain experience (Moldofsky, 2008). Recent reviews of the literature have established the connection between sleep and pain, although the direction of this relationship remains unclear (Finan et al., 2013; Moldofsky, 2001). This dissertation sought to examine the daily relationship between sleep and …

Longitudinal Change In Regional Cortices And Fluid Intelligence, Peng Yuan

Wayne State University Dissertations

Fluid intelligence (Gf) and crystalized intelligence (Gc) are two factors of the general intelligence. They have distinct age-related trajectories of change. Jung and Haier proposed Parieto-Frontal Integration Theory (P-FIT, 2007) to account for the inter-person variance in reasoning intelligence. Some brain regions such as prefrontal, parietal, temporal and anterior cingulate cortices were included in the P-FIT model and were hypothesized to be involved in fluid reasoning task. Therefore, in the current study, we examined latent growth curves (LGC) of longitudinal change in Gf, Gc, prefrontal cortex, parietal cortex, anterior cingulate, temporal cortex and primary visual cortex. Forty-six healthy middle-aged and …

Mental Health Service Utilization Among African-American Adolescents, Marilyn Franklin

Wayne State University Dissertations

Underutilization of mental health services by ethnic minorities has been identified as a major public health threat by the U.S. Department of Health and Human Services (2001). Research on ethnic disparities has focused on identifying the sociodemographic correlates of between group differences in treatment attendance. The current study adds to the utilization literature by exploring within group differences amongst a sample of African-American families. Based on extant literature related to treatment utilization in other samples, this study examined the associations between multiple modifiable factors and adolescent treatment engagement amongst 90 African-American caregiver-adolescent dyads.

Consistent with previous research, psychological symptoms, functional …

Family resilience in this study includes family quality of life, locus of control, sense of coherence, perceived stress, uncertainty, severity, and demands. The participants in this study were 153 parents of children diagnosed with ASD. The parents were members of the Autism Society of Oakland County. The participants completed a survey comprised of six scales (Parental Concerns Questionnaire, Perceived …

Health-Related Behaviors In Low-Income, Minority Youth: The Role Of Motivation, Basic Needs, Mental Health, And Environmental Barriers, Brittany A. Kohlberger

Wayne State University Dissertations

Engaging in health-related behaviors, such as exercise, healthy eating, and sleep hygiene, are associated with fewer externalizing and internalizing behavior problems and higher self-esteem, suggesting that there may be large benefits to engaging in health-related behaviors during the transitional developmental phase of adolescence (Ong, Wickramaratne, Tang, & Weissmann, 2006; Stathopoulou, Power, Berry, Smits, & Otto, 2006). The purpose of the current study was to identify key psychological processes and external factors that may boost or impede youths' motivation and engagement in health-related behaviors. Specifically, we expected that higher levels of psychological symptoms and environmental barriers will be significantly, negatively associated …

Accumulation Of Subcortical Iron As A Modifier Of Volumetric And Cognitive Decline In Healthy Aging: Two Longitudinal Studies, Ana Marie Daugherty

Wayne State University Dissertations

Accumulation of non-heme iron in the brain has been theorized as a cellular mechanism underlying global neural and cognitive decline in normal aging and neurodegenerative disease. Relatively few studies of brain iron in normal aging exist and extant studies are almost exclusively cross-sectional. Here, I estimated iron content via T2* and measured volumes in several brain regions in two independent samples of healthy adults. The first sample (N = 89) was measured twice with a two-year delay; and the second sample (N = 32) was assessed four times over a span of 7 years. Latent models estimated change in iron …

Coping Similarity And Psychosocial Risk Factors In Couples With Chronic Pain, Amy M. Williams

Wayne State University Dissertations

Chronic pain is an important public health problem that is associated with a host of negative individual and relationship outcomes. Chronic pain is a chronic stressor that both the individual in pain and their spouse must cope with. The current study examined how pain coping similarity within the couple predicted not only patient adjustment, but also spouse adjustment in a longitudinal study. Participants were 108 heterosexual couples in which one partner had chronic pain. The participants completed measures at 3 time points at 6 month intervals. Both the patient and spouse individually completed questionnaires pertaining to their marriage, mood, pain …

An Analysis Of Self: The Development And Assessment Of A Measure Of Selfobject Needs, Eamonn Arble

Wayne State University Dissertations

The theory of self psychology as advanced by Heinz Kohut (1971, 1977, 1984) emphasized the importance of early developmental experiences, most centrally, the empathic attunement of caregivers as key nutrients for fostering the capacity for healthy self-regulation and interpersonal relations. Kohut elaborated three critical selfobject needs (i.e., idealizing, mirroring, and twinship) that were ideally satiated by these early experiences, deeming the fulfillment of these needs as essential for developing a healthy sense of self, capable of sustaining ambitions, self-soothing, and caring for others and oneself. In the case of psychopathology, these needs were theorized to have gone unmet, leaving the …

The Effects Of Men's Acute Alcohol Intoxication, Overperception Of Sexual Intent, Interpersonal Rejection And Testosterone On Aggression Toward Women, Rhiana Marie Wegner

Wayne State University Dissertations

This study was designed to assess Abbey's (1991; 2002; 2011) model, which posits that acute alcohol intoxication increases the likelihood of sexual aggression at two stages of a cross-sex interaction. Early on, the cognitive impairments induced by alcohol encourage a potential perpetrator to overperceive a woman's level of sexual intent. Later, if the man's sexual advances are rejected, intoxication encourages an aggressive response. This research expands on the previous literature by examining: 1) both stages of Abbey's model in a single study, 2) rejection from a woman as a potential trigger for aggression, and 3) behavioral (past sexual assault perpetration), …

Associations Between Maternal Maltreatment-Specific Shame, Maternal-Infant Interactions, And Infant Emotion Regulation, Rena A. Menke

Wayne State University Dissertations

The current study focuses on maltreatment-specific shame as a potential mechanism by which mothers' histories of childhood maltreatment might influence parenting and infant emotion regulation. Shame is a common reaction to childhood maltreatment, and the persistence of maltreatment-specific shame is associated with psychopathology and other psychosocial problems long after the abuse ends (Andrews, Brewin, Rose, & Kirk, 2000; Feiring, Taska, & Lewis, 2002a; Feiring & Taska, 2005). Despite being associated with psychopathology (e.g., depression, PTSD), shame is a conceptually distinct abuse-specific reaction that can interfere with self and interpersonal development (Feiring, Cleland & Simon, 2010; Feiring, Simon, Cleland, 2009; Feiring, …

Friend Or Foe: The Effect Of Shared Group Status On Aggressiveness And Testosterone In Response To Provocation, Eric William Fuller

Wayne State University Dissertations

Previous research has found that individuals display behavioral and hormonal differences when engaged in competition with natural and experimental ingroup and outgroup members. The current work expands on this line of research by examining the impact of shared group status on reactive aggression in response to provocation. Using a previously validated measure of reactive aggression, participants were provoked by and given a chance to aggress on to either a racial ingroup or outgroup member. Participants also provided saliva samples to allow for monitoring changes in testosterone. It was hypothesized that behavioral aggression would be predicted by changes in testosterone and …
