Family Care Partners Of Chronically Ill Older Adults: The Role Of Uncertainty In Illness, Jillian Pine

Dissertations

Abstract This study integrated research on family care partners of older adults and

research on uncertainty in chronic illness. Previous findings were extended by examining care partners of older adults with multiple chronic conditions and highlighting early-stage undiagnosed cognitive impairment as a uniquely unclear condition. Participants were 45 women assisting community-dwelling, earlier generation older adults with multiple chronic health conditions and a prognosis of more than six months. Online survey data were used to test the hypotheses that increased illness uncertainty would be associated with increased care partner-recipient relationship strain and increased care partner perceived stress. This study also hypothesized …

Impact Of The Serotonin Transporter Polymorphism On Emotion Identification In Healthy Older Adults, Staci Erin Scott

Dissertations

Older adults exhibit reduced accuracy and efficiency for identifying facial emotion expressions yet it is unclear how genetic or cognitive variables influence these findings. This study examined the impact of serotonin transporter polymorphism 5-HTTLPR on patterns of explicit emotion identification accuracy and reaction time (RT) in healthy older adults. The impact of 5-HTTLPR on measures of processing speed, attention, and executive function as well as correlations between cognitive measures and emotion identification measures were also examined. Methods: Forty-one individuals over the age of 50 were genotyped for bi-allelic and tri-allelic variants of 5-HTTLPR and administered an emotion recognition paradigm and …

Structural Models Of Comorbid Anxiety And Depression In A Primary-Care Older Adult Sample: Effect Of Medical Illness Severity, Threat, Chronicity, And Progressiveness On Model Fit, William Michael Palmer

Dissertations

Recent research suggests that anxiety disorders may be more common in later life than previously thought. Among other factors, the presence of comorbid mood disorders and medical illness confounds accurate assessment and diagnosis of these conditions in the elderly. There have been few studies, however, examining the structural relationships between anxiety and depression with older-adult samples, and even fewer have considered the effect of medical illness on these relationships. This study examined three established structural models of anxiety and depression, using a clinical sample of older adults seeking treatment in a primary-care setting (N = 2,163). It was hypothesized that …
