Show moreInjury to the brain can range in cause, severity, and outcomes. Individuals with brain injury may experience both physical and cognitive impairments. Not only can a patient experience a wide range of symptoms, these symptoms also can vary drastically in severity. Research has shown that these symptoms play a role in a person’s quality of life following injury: the worse a person’s symptoms are, the lower they report their quality of life. However, recent research suggests that psychosocial factors may mediate the relationships between disability severity and quality of life across multiple rehabilitation populations. Two of the previously researched psychosocial constructs include social support and a sense of mastery over the disability or disease. The purpose of this study was to examine a structural model hypothesizing the mediating role of these two constructs on the relationship between symptom severity and quality of life among adults with brain injury. Participants in this study included 183 individuals with brain injury recruited through state brain injury organizations across the United States to participate in an online survey study. Using structural equation modeling (SEM), results demonstrated good model fit. (χ2(15, n = 183) = 13.68). Normed Bentler-Bonnet fit index (NFI) was .97; Goodness-of-Fit statistic (GFI) was .98; Adjusted-goodness-of-fit (AGFI) was .96; and Comparative fit index (CFI) was 1.00 (indices exceeding .90 indicate acceptable fit). Examination of the direct effects showed that perceived social support and sense of mastery are negatively associated with symptom severity (-.19 and -.66 respectively). Additionally, perceived social support was positively associated with mastery (.30). Both mastery and social support were moderately related to quality of life (.46 and .53, respectively). Rmediation analysis revealed perceived social support and mastery fully mediate the relationship between symptom severity and quality of life. Additionally, mastery partially mediated the relationship between social support and quality of life. These findings highlight the importance of incorporating these psychosocial factors into clinical interventions with hopes of increasing levels of perceived social support and mastery, and ultimately promoting quality of life. Further research is needed to explore the best strategies to increase support and mastery within the brain injury population and to identify additional psychosocial factors that may be mediators of quality of life.

Show moreThis research is focused on quantitatively investigating and comparing the environmental and social sustainability of people’s lifestyles in terms of embodied energy, operational energy use, and overall satisfaction with their quality of life in both downtown high-rise and suburban low-rise living using Chicago, IL and a surrounding suburban area of Oak Park, IL as a case study. Specifically, in both cases, the study seeks to evaluate factors such as the embodied energy of the materials that comprise buildings in each location; the predicted and actual monthly energy consumption of the homes; travel via all modes of transport including automobile, public transport, walking, and biking; and the embodied and operational energy of the infrastructure to support each mode of transportation. In addition, this research also engages with the individual building occupants, including single individuals, couples, and families, in a large subset of downtown and suburban Chicago households to directly evaluate perceptions of their life satisfaction and sense of community, which offers a unique direct comparison between dense high-rise and suburban low-rise living. The findings of the study show that downtown high-rise living in Chicago accounts for approximately 58% more life-cycle energy per person per year than Oak Park low-rise living, on average, contrary to some common beliefs (best estimates were ~260 and ~165GJ/person/year, respectively). Building operational energy was estimated to be the single largest contributor of the total life-cycle energy in both the downtown high-rise and suburban low-rise cases, followed by vehicle OE. The findings of the study also show that downtown high-rise residents were associated with higher life satisfaction than suburban low-rise residents when controlling for demographic differences in the research sample. Residence type was not found to be associated with sense of community when controlling for demographic differences, and the factor that was found to be significantly associated with sense of community was household size in the research sample. Also, accessibility and safety were found as the strongest predictors of overall residential environment for individuals.

Show moreEpilepsy is the most common neurological disorder worldwide with a heterogeneous range of negative symptoms. Current treatments for epilepsy have side effects that can negatively impact the quality of a person’s life. Alternative treatments are being explored, including marijuana. This study aimed to understand marijuana use in adults with epilepsy across U.S. states. Rates of use, preferred method of use, and reasons to use and not use marijuana were examined. Additionally, levels of comfort discussing marijuana compared to other treatment options and with different types of providers were explored. Lastly, this was one of the first studies to examine the relationship between quality of life (QOL) and marijuana use for people with epilepsy. Participants included 128 individuals with epilepsy from 26 states, with non-legal states having significantly fewer people who reported using marijuana. Smoking was reported as the primary method of use, knowing someone else that uses as their primary reason for using, and health concerns as the primary reason not to use. There was no difference in level of comfort discussing marijuana compared to other treatments, and participants reported feeling most comfortable discussing marijuana with neurologists compared to other providers. Finally, total QOLIE-31 and the social functioning subscale were significantly lower among marijuana users; however, this difference did not remain when anxiety was entered as a covariate. In fact, the relationship between anxiety and QOL was significant, with anxiety accounting for η2 = .12 to η2 = .57 of the variance in QOLIE-31 subscale scores, controlling for marijuana use. Findings from this study further the understanding of marijuana use by people with epilepsy in the United States.

Show moreIndividuals with autism spectrum conditions (ASC) face poorer quality of life (QOL) and psychological well-being. Sense of community (SOC) has been studied in the general population as well as in other disability populations and found to be associated with increased QOL outcomes. However, SOC has never been examined quantitatively in the ASC population. Additionally, a number of communities exist online, and there has been recent research showing that people may feel sense of virtual community (SOVC), which may be particularly important to the ASC population, as internet use is higher in the population, and people with ASC report positive experiences with online communication and relationships. The purpose of this study was to examine SOC and SOVC in the ASC population. A sample of 60 participants with ASC completed an online survey about their communities, SOC, SOVC, QOL, and psychological distress, and their results were compared with a sample of 60 general population participants (N = 120). Results indicated that people with ASC reported participating in a greater number of smaller relational communities compared to the general population sample. There were no significant differences between the ASC and general population samples on levels of SOC or SOVC, suggesting that the differential relationship of the ASC group with their communities does not reduce the experience of SOC. SOC significantly contributed to QOL but not psychological distress. Results indicated that the magnitude of the relationship between SOC and SOVC on QOL was not different between those with ASC and those in the comparisons sample. Findings from this study help frame the different ways in which people with ASC interact with their communities and inform individual and community-level interventions.
