Openness, Neuroticism, Conscientiousness, And Family Health And Aging Concerns Interact In The Prediction Of Health-Related Internet Searches In A Representative U.S. Sample, Tim Bogg, Phuong T. Vo

Psychology Faculty Research Publications

Recent estimates suggest 60 % of the U.S. adult population uses the Internet to find health-related information. The goal of the present study was to model health-related Internet searches as a function of an interdependent system of personality adaptation in the context of recent health and aging-related concerns. Assessments of background factors, Big Five personality traits, past-month health and aging-related concerns, and the frequency of past-month health-related Internet searches (via Google, Yahoo, AOL, Bing, or some other search engine) were obtained from a representative U.S. sample (N = 1,015). Controlling for background factors, regression analyses showed more frequent health-related …

Comparing The Characteristics Of Homeless Adults In Poland And The United States, Paul A. Toro, Karen Hobden, Kathleen Wyszacki Durham, Marta Oko-Riebau, Anna Bokszczanin

Psychology Faculty Research Publications

This study compared the characteristics of probability samples of homeless adults in Poland (N = 200 from two cities) and the United States (N = 219 from one city), using measures with established reliability and validity in homeless populations. The same measures were used across nations and a systemic translation procedure assured comparability of measurement. The two samples were similar on some measures: In both nations, most homeless adults were male, many reported having dependent children and experiencing out-of-home placements when they themselves were children, and high levels of physical health problems were observed. Significant national differences were …

Change In Coping And Defense Mechanisms Across Adulthood: Longitudinal Findings In A European-American Sample, Manfred Diehl, Helena Chui, Elizabeth L. Hay, Mark A. Lumley, Daniel Grühn, Gisela Labouvie-Vief

Psychology Faculty Research Publications

This study examined longitudinal changes in coping and defense mechanisms in an age- and gender- stratified sample of 392 European-American adults. Nonlinear age-related changes were found for the coping mechanisms of sublimation and suppression and the defense mechanisms of intellectualization, doubt, displacement, and regression. The change trajectories for sublimation and suppression showed that their use increased from adolescence to late middle age and early old age, and remained mostly stable into late old age. The change trajectory for intellectualization showed that the use of this defense mechanism increased from adolescence to middle age, remained stable until late midlife, and started …

The Effect Of Gaba A Antagonism On Locomotor Activity And Dopamine Release In The Mouse Caudate Putamen Following Acute Toluene Inhalation: An In-Vivo Microdialysis Study, Sean Callan

Wayne State University Theses

Toluene is ubiquitous solvent commonly inhaled recreationally. Despite its frequency of misuse, there is little understanding of how toluene acts within the brain. To examine this, this master's thesis examined the impact of acutely inhaled toluene on dopamine (DA) release in the mouse CPu in vivo using microdialysis techniques. Toluene inhalation produced dose-dependent increases in DA levels as well as changes in locomotor activity. These effects were potentiated by pre-treatment with the GABAA antagonist bicuculline via reverse microdialysis delivery. These results suggest that the DA dynamics of toluene abuse are related to toluene's previously explored effects on the GABA system. …

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 …

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 …

Inattention And Hyperactivity Among Preschool Age Children Born Prematurely, Andrew Heitzer

Wayne State University Theses

A large body of literature shows that compared to children born at term, preterm- children are at increased risk for difficulties with inattention and hyperactivity. Less consistency exists, however, in the limited body of research exploring the contribution of early biological risk to behavioral disinhibition within the population of children born prematurely. Therefore, our goal was to examine perinatal variables that may influence activity level and hyperactivity among preterm preschoolers. Ninety-eight preterm (23.4 - 33.9 weeks gestation) preschoolers (3-4 years) participated in the study. Direct measures of inattention and hyperactivity as well as parental ratings were used to evaluate behavior. …

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 …
