Beyond My Control: The Role Of Sense Of Control On Cognitive Functioning And Depressive Symptoms In Older Adults, Sabine Lohmar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Depression and depressive symptoms commonly coincide with mild cognitive impairment (MCI) and dementia in older adults (Ismail et al., 2017; Panza et al., 2010), with its prevalence varying based on dementia severity, diagnostic criteria, and dementia subtype (Chi et al., 2015; Ismail et al., 2017; Leung et al., 2021; Lopez et al., 2003). This relationship is hypothesized to exist for a variety of reasons, including that depressive symptoms occur as an emotional response to cognitive functioning (Bennett & Thomas, 2014; Richard et al., 2013). Emotional responses may be explained by a decline in sense of control, or the belief in …

An Intersectional Approach To Examining The Impact Of Cigarette Taxes On Tobacco Use By Urbanization Level, Andrea R. Milstred

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rates of traditional tobacco use have reached a century-level low though not universally with some vulnerable populations continuing high rates of tobacco use, such as those located in geographically isolated areas of the United States (US). Rural populations experience a unique set of challenges (i.e., decreased access to health promoting resources, high density of tobacco retailers, increased pro-tobacco advertising) that compound to produce a “cumulative disadvantage” ultimately increasing their risk of tobacco use. To curb and prevent tobacco use, tobacco control policies, such as excise taxes, can be implemented. At least one study suggests tobacco control policies are less effective …

Examining The Relationships Among Value Placed On Autonomy, Use Of Compensatory Control Strategies, And Suicidal Ideation In Older Adults, Catherine Huang Ju

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rates of suicide in older adults are higher than those found in the general United States population. A variety of risk factors unique to older adulthood contribute to these numbers. Greater value placed on one’s own autonomy is related to suicidal ideation in older adults, but no research has yet been done to examine the mechanisms underlying this relationship. As individuals age and functional impairment increases, older adults generally engage in compensatory primary control strategies (e.g., seeking help) but those who prioritize independence and self-directedness – i.e., place a high value on autonomy – engage in fewer compensatory primary control …
