Projecting, Persuading, & Protecting: A Mixed Methods Analysis Of Adult Children’S Predictions Of Parents’ Quality-Of-Life Valuations In Serious Illness States, Jessica Hahne

Arts & Sciences Electronic Theses and Dissertations

Older adults often face complex serious illness decisions and involve their adult children as shared or surrogate decision makers. However, previous research asking family members to predict older adults’ treatment preferences in serious illness situations typically shows poor concordance with older adults’ actual preferences. In the current mixed methods analysis, we surveyed older adults (n = 38) on their health state valuations in five serious illness scenarios. Two of their adult children (n = 76) predicted their parent’s preferences. Families also participated in a semi-structured conversation to discuss their preferences and predictions.

Quantitative analyses showed that parents’ average valuations were …

On Arousal And The Internal Regulation Of Brain Function: Theory And Evidence Across Modalities And Species, Ryan Raut

Arts & Sciences Electronic Theses and Dissertations

The brain is an organ. It is subject to the same physiological regulatory processes that engage the rest of the body’s organs, sculpted over hundreds of millions of years to sustain life so effectively. The central message of this thesis is that the holistic functioning of the brain, rather than operating at some level above or independent from these systemic regulatory processes, is deeply related to them. In short, as our limited attention spans might suggest: brain function is internally regulated. I propose that this internal regulation is a primary function of intrinsic brain activity. Chapter 2 provides a theoretical …

A Secondary Data Analysis Of The Prevalence Of Reported Dementia And Subjective Cognitive Decline Across U.S. National Surveys, Matthew C. Picchiello

Arts & Sciences Electronic Theses and Dissertations

Within the United States, many large-scale, nationally representative studies exist with the goal of tracking and monitoring aspects of health. These studies are often used to establish the prevalence of dementia and subjective cognitive decline (SCD) in the population. The goal of the current study is to examine how different population-based studies probe respondents about conditions related to cognitive impairment, and to assess similarities and differences in point estimates. We reviewed eight studies and identified comparable items related to dementia and SCD. We calculated design-appropriate point prevalence estimates and compared weighted estimates across studies, finding a wide range and statistically …

Examining Mental Health In Northern Haiti, Michael Galvin

Arts & Sciences Electronic Theses and Dissertations

Mental health is a severely neglected field in low- and middle-income countries globally. Populations in countries such as Haiti demonstrate a high level of need for mental health services despite a lack of services and trained professionals. In addition to the dearth of biomedical services, local belief systems and explanatory models lead a majority of the population to rely on traditional medicine as their first option for care. The goal of this dissertation is to characterize mental health beliefs, practices, and services in northern Haiti by examining the relationship between traditional beliefs and mental illness, assessing the impact of traumatic …

Parental Psychological Distress After Prenatal Diagnosis Of Congenital Heart Disease: Patterns, Predictors, And Impact On Early Outcomes., Kathryn Mangin-Heimos

Arts & Sciences Electronic Theses and Dissertations

Congenital heart disease (CHD) is the most common birth defect and is often diagnosed during pregnancy. The transition to parenthood after prenatal diagnosis can be particularly challenging. Both mothers and fathers are at elevated risk for psychological distress, yet early distress frequencies and patterns have not been well characterized. The impact of psychological distress on parents’ perceptions of their readiness to care for their infant after hospital discharge is currently unknown. The association of psychological distress with early infant neurodevelopment has also been under investigated. To examine these gaps in knowledge, we conducted a single center, prospective cohort study of …

Executive Abilities And Academic Achievement In Children With Sickle Cell Disease, Erika Wesonga

Arts & Sciences Electronic Theses and Dissertations

Academic achievement is crucial to a child’s psychosocial and occupational success (Davaoudzadeh et al., 2015; Margari et al., 2013). In children with sickle cell disease (SCD), a genetic disorder resulting in abnormal hemoglobin and significant neurologic sequelae, poor academic achievement is common (e.g. Wang et al., 2001). Studies of typically-developing children have revealed links between academic achievement and neuropsychological abilities, particularly higher-order executive abilities that are mediated primarily by frontal brain regions (Altemeier et al., 2006; Bull & Scerri, 2001). In children with SCD, there is a wealth of evidence that executive abilities are impaired (Berkelhammer et al., 2007), but …

The Effect Of Retrieval Practice On Vocabulary Learning For Children Who Are Deaf Or Hard Of Hearing, Casey Krauss Reimer

Arts & Sciences Electronic Theses and Dissertations

The goal of the current study was to determine if students who are deaf or hard of hearing (d/hh) would learn more new vocabulary words through the use of retrieval practice than repeated exposure (repeated study). No studies to date have used this cognitive strategy—retrieval practice—with children who are d/hh. Previous studies have shown that children with hearing loss struggle with learning vocabulary words. This deficit can negatively affect language development, reading outcomes, and overall academic success. Few studies have investigated specific interventions to address the poor vocabulary development for children with hearing loss. The current study investigated retrieval practice …

The Role Of Personality In The Development Of Health Disparities During Late-Mid Life, Juliette Mcclendon Iacovino

Arts & Sciences Electronic Theses and Dissertations

Objectives: The current study examined race/gender disparities in initial levels and trajectories of self-reported physical and mental health, and health care utilization, as well as the impact of personality and stressful life events on race/gender disparities. We hypothesized that health disparities would remain stable or decrease over time; that at-risk personality traits (e.g., high neuroticism) would have a more robust negative impact on health for black participants; that trust would mediate racial disparities in health; and that personality traits would moderate the association between stressful life events and health trajectories differentially across race/gender. Methods: Analyses utilized the first six waves …

Prospective Memory Impairment In Parkinson Disease Without Dementia: Cognitive Mechanisms And Intervention, Erin R. Foster

Arts & Sciences Electronic Theses and Dissertations

Cognitive impairment among non-demented individuals with Parkinson disease (PD) produces significant disability, reduced quality of life, and restricted participation. This dissertation will cover PD-related impairment in prospective memory, or the ability to remember to execute delayed intentions at the appropriate moment in the future. Prospective memory impairment in PD is increasingly recognized as a functionally and clinically relevant problem and viable target for cognitive intervention. To lay the groundwork for the development of effective interventions for prospective memory in PD, this dissertation examines the cognitive mechanisms underlying prospective memory impairment in PD and the potential of training in a targeted …

Mental Health And Academic Outcomes Among Adolescents In South Korean Orphanages, Hollee Ann Mcginnis

Arts & Sciences Electronic Theses and Dissertations

Research conducted over the past 100 years in Western nations support the adverse effects of orphanages on children’s emotional, developmental, and social well-being as well as economic costs to society (Save the Children UK, 2009; Bakermans-Kranenburg, Van IJzendoorn & Juffer, 2008; Williams & Greenberg, 2010). Globally, the number of orphaned and abandoned children is conservatively estimated to be around 143 million, of whom the majority reside in Asia, followed by Sub-Saharan Africa (UNICEF, UNAIDS, & USAID, 2004). South Korea (hereafter “Korea”) is an exemplary nation for study because it has a well-established child welfare system, including family-based alternatives (domestic and …

Relationships Between Age And White Matter Integrity In Children With Phenylketonuria, Erika M. Wesonga

Arts & Sciences Electronic Theses and Dissertations

Objective: Phenylketonuria (PKU) is a hereditary metabolic disorder associated with cognitive compromise. Diffusion tensor imaging (DTI) has allowed detection of poorer microstructural white matter integrity in children with PKU, with decreased mean diffusivity (MD) in comparison with healthy children. However, very little research has been conducted to examine the trajectory of white matter development in this population. The present study investigated potential differences in the developmental trajectory of MD between children with early- and continuously-treated PKU and healthy children across a range of brain regions.

Methods: Children with PKU (n = 31, mean age = 12.2 years) were …
