Predictors Of Cooperative And Externalizing Behaviors In Siblings Of Children With Disabilities, Christine Rae Platt Sep 2013

Predictors Of Cooperative And Externalizing Behaviors In Siblings Of Children With Disabilities, Christine Rae Platt

Theses and Dissertations

Objective: To examine whether caregiver burden, parenting style, and sibling relationships in families raising a child with a disability (CWD) predict cooperative and externalizing behaviors in typically-developing sibling (TDS). Methods: This correlational study included 189 families raising both a CWD and a TDS. Mothers and fathers completed self-report questionnaires on caregiver burden, sibling relationships, parenting style, and TDS cooperative and externalizing behaviors. Results: Authoritative parenting was positively associated with cooperative behaviors, whereas authoritarian parenting was positively associated with externalizing behaviors. Hierarchical regression revealed caregiver burden was a significant predictor of cooperative and externalizing behaviors; however, when parenting style was added …


Memory Training For Older Adults With Mild Cognitive Impairment, Charlotte A. Allsop, Dr. Barbara Heise Sep 2013

Memory Training For Older Adults With Mild Cognitive Impairment, Charlotte A. Allsop, Dr. Barbara Heise

Journal of Undergraduate Research

Dementia is manifested by a severely limited memory and performance of cognitive abilities. Mild Cognitive Impairment (MCI) is an early stage of memory loss which can later lead to Dementia. It has been proven that you can delay cognitive dysfunction, e.g. memory, by “training the brain” through various cognitive exercises. However, those with MCI are difficult to detect because their memory loss is subtle. The purpose of this study is to first, enhance MCI recognition in elderly individuals and second, to determine the efficacy of memory training in the community.

Psychometric Assessment Of The Depressive Cognition Scale In Caregivers Of Persons With Dementia, Abir K. Bekhet, Jaclene Zauszniewski Sep 2013

Psychometric Assessment Of The Depressive Cognition Scale In Caregivers Of Persons With Dementia, Abir K. Bekhet, Jaclene Zauszniewski

College of Nursing Faculty Research and Publications

Caregivers of persons with dementia are prone to depression. Early identification of cognitive depressive symptoms is important to prevent the development of clinical depression. The Depressive Cognition Scale (DCS) can be used for early detection, but the scale's psychometrics have not been tested in caregivers of persons with dementia. In this study, 80 caregivers of persons with dementia completed the eight-item DCS and measures of caregiver burden and resourcefulness. A Cronbach's alpha of .88 indicated internal consistency. Construct validity was supported by significant correlations with caregiver burden (r = .40; p < .001) and resourcefulness (r = –.54; p < .001). Principal components factor analysis resulted in two factors in which five items loaded cleanly on one factor and two items have cross-loadings. Because prior factor analysis in previous studies resulted in one factor, we did confirmatory factor analysis in which we forced the items on one factor. All the items loaded on the single factor and the amount of variance explained was 55.99%. The findings suggest the DCS is useful for early detection of depression in caregivers of persons with dementia.

Use Of Participant-Generated Photography In A Research Contribution Course, Maryellen Thompson

The Open Journal of Occupational Therapy

This paper describes the use of small, qualitative studies focused on interviews done with participant-generated photographs as an effective and efficient way of teaching research to entry-level masters students. A comparison of using time-use diaries vs. participant-generated photography is presented to explicate the research process and demonstrate the advantages of using photography, including ease of data collection and data sharing. Over a three-year period of using participant-generated photographs as a guide for semi-structured interviews, students have consistently expressed enjoyment of the research process and increased empathy with their research participants.


Cardiac Fibroblast-Dependent Extracellular Matrix Accumulation Is Associated With Diastolic Stiffness In Type 2 Diabetes., Kirk R. Hutchinson, C. Kevin Lord, T. Aaron West, James A. Stewart Aug 2013

Cardiac Fibroblast-Dependent Extracellular Matrix Accumulation Is Associated With Diastolic Stiffness In Type 2 Diabetes., Kirk R. Hutchinson, C. Kevin Lord, T. Aaron West, James A. Stewart

CAS Publications

Cardiovascular complications are a leading cause of death in patients with type 2 diabetes mellitus (T2DM). Diastolic dysfunction is one of the earliest manifestations of diabetes-induced changes in left ventricular (LV) function, and results from a reduced rate of relaxation and increased stiffness. The mechanisms responsible for increased stiffness are not completely understood. Chronic hyperglycemia, advanced glycation endproducts (AGEs), and increased levels of proinflammatory and profibrotic cytokines are molecular pathways known to be involved in regulating extracellular matrix (ECM) synthesis and accumulation resulting in increased LV diastolic stiffness. Experiments were conducted using a genetically-induced mouse model of T2DM generated by …

Health Sciences Faculty Publications

High-fat meal consumption alters the circulating cytokine profile and contributes to cardiometabolic diseases. A prior bout of exercise can ameliorate the triglyceride response to a high-fat meal, but the interactive effects of exercise and high-fat meals on cytokines that mediate cardiometabolic risk are not fully understood. We investigated the effects of prior exercise on the responses of circulating tumor necrosis factor-a (TNF-a), interleukin-6 (IL-6), IL-8, leptin, retinol-binding protein 4 (RBP4), vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), placental growth factor (PlGF), and soluble fms-like tyrosine kinase-1 (sFlt-1) to a high-fat meal. Ten healthy men were studied before …

Marcus Institute of Integrative Health Faculty Papers

This study assessed the effectiveness of a mindfulness-based program, Learning to BREATHE, on adolescent emotion regulation. Participants included 216 regular education public high school students with pretest and posttest data participating in the program or instruction-as-usual comparison condition. Program participants reported statistically lower levels of perceived stress and psychosomatic complaints and higher levels of efficacy in affective regulation. Program participants also evidenced statistically larger gains in emotion regulation skills including emotional awareness, access to regulation strategies, and emotional clarity. These findings provide promising evidence of the effectiveness of Learning to BREATHE on the development of key social-emotional learning skills.

Medicaid Expansion, Long-Term Care Financing In Retirement States And The Post World War Ii Birth Cohort, Toni P. Miles

Center for Policy Research

This policy brief contains a formal consideration of ideas discussed during a presentation to the 2012 Syracuse Seminar on Aging. Like most briefs, it will appeal to policy makers and academics craving detailed demographic, fiscal and policy data. Before diving into this brief, I would encourage readers to view the presentation video (available at http://www.youtube.com/ watch?v=bsv8K7DdJFY). As you will see, the seminar was informal and the discussion was wide ranging. In contrast, this brief focuses on limitations faced by states as they finance longterm care. It is primarily concerned with the Medicaid expansion and growing need for care as the …


Successful Aging And Creativity : An Investigation On Functional Status And Psychological Wellbeing In Older Adults, Mirie E. Levy Aug 2013

Successful Aging And Creativity : An Investigation On Functional Status And Psychological Wellbeing In Older Adults, Mirie E. Levy

Loma Linda University Electronic Theses, Dissertations & Projects

Objectives: While the literature supports the maintenance of functional status as integral to successful aging, the relationship of creativity on functional status has received little attention. Creativity has been associated with health and aging in the research but only a small number of studies have examined creativity interventions to enhance functional status and boost psychological wellbeing.

Methods: A pretest-posttest quasi-experimental design was used to investigate an 8-week creativity intervention on functional status and psychological wellbeing in older adults. Sample subjects were 92 men and women all over age 60. A series of two-way mixed ANOVAs measured differences between treatment and …

Sociology Faculty Articles and Research

Purpose—This study examined how race-ethnicity, nativity, and education interact to influence disparities in cardiovascular (CV) health, a new concept defined by the American Heart Association (AHA). We assessed whether race-ethnicity and nativity disparities in CV health vary by education, and whether the foreign-born differ in CV health from their US-born race-ethnic counterparts with comparable education.

Methods—We used data from the 2009 California Health Interview Survey to determine the prevalence of optimal CV health metrics (based on selected AHA guidelines) among adults ages 25 and over (n = 42,014). We examined the interaction between education and ethnicity-nativity, comparing predicted …


Aboriginal And Non-Aboriginal Students Learn About Natural Health Products From Different Information Sources, Sarah O. Alkholy, Samiah N. Alqahtani, Audrey Cochrane, Maria Pontes Ferreira, Fidji Gendron Jul 2013

Aboriginal And Non-Aboriginal Students Learn About Natural Health Products From Different Information Sources, Sarah O. Alkholy, Samiah N. Alqahtani, Audrey Cochrane, Maria Pontes Ferreira, Fidji Gendron

Nutrition and Food Science Faculty Research Publications

Natural health products (NHPs) include naturally derived botanical and nonbotanical products. Past research indicates a high prevalence of NHPs use amongst adults in the United States and Canada but does not clearly characterize NHPs use amongst students, ethnic variations of such use, or how users learn about NHPs. We hypothesize that there is a difference between Aboriginal and non-Aboriginal students in how they learn about NHPs. To investigate this question, we conducted a cross-sectional study at First Nations University of Canada and the University of Regina, Saskatchewan, Canada, during the fall of 2011. Aboriginal (n=214) and non-Aboriginal (n=749) students participated …

Considering Positive Psychology Constructs Of Life Satisfaction And School Connectedness When Assessing Symptoms Related To Attention-Deficit/Hyperactivity Disorder, Emily B. Mancil, Jason M. Bird, Mike Lyons, Kathryn Van Eck, Bradley H. Smith Jun 2013

Considering Positive Psychology Constructs Of Life Satisfaction And School Connectedness When Assessing Symptoms Related To Attention-Deficit/Hyperactivity Disorder, Emily B. Mancil, Jason M. Bird, Mike Lyons, Kathryn Van Eck, Bradley H. Smith

Journal of Human Sciences and Extension

Children and adolescents diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) demonstrate significant difficulty with academic and behavioral functioning. This, in turn, can lead to lower educational attainment and vocational achievement, which has serious long-term consequences and costs to individuals and society (Barkley, 2002, 2006; Mannuzza, Klein, Bessler, Malloy, & LaPadula, 1993). Researchers from a positive psychology framework suggest that ADHD symptoms (i.e., inattention, hyperactivity/impulsivity) alone may not fully explain academic impairment (Diener, Scollon, & Lucas, 2004). From the standpoint of positive psychology, life satisfaction and school connectedness are important constructs that examine positive life functioning; however, they have been understudied, particularly in …

Oxidative stress is involved in age-related cognitive decline. The dietary antioxidants, carotenoids, tocopherols, and vitamin A may play a role in the prevention or delay in cognitive decline. In this study, sera were obtained from 78 octogenarians and 220 centenarians from the Georgia Centenarian Study. Brain tissues were obtained from 47 centenarian decedents. Samples were analyzed for carotenoids, α-tocopherol, and retinol using HPLC. Analyte concentrations were compared with cognitive tests designed to evaluate global cognition, dementia, depression and cognitive domains (memory, processing speed, attention, and executive functioning). Serum lutein, zeaxanthin, and β-carotene concentrations were most consistently related to better cognition …
