Sleep Self-Efficacy, Loneliness, And Physical Activity: Assessing The Pathways Between Sleep Quality And Mental Health Using Structural Equation Modeling, Amber M. Fox
Theses and Dissertations
Although there is robust empirical support that poor sleep contributes to declines in mental health, explanations of this relationship remain unclear. The purpose of the present study was to examine the pattern of associations between sleep quality, sleep self-efficacy, loneliness, physical activity, and mental health among U.S. adults across the lifespan, and whether they differed by gender or age group. A structural equation model with invariance analysis was developed and examined data from 2,300 adults (Mage = 44.1, SD = 16.78) participating in the online study Investigating Sleep Longitudinally Across Normal Development (ISLAND). Sleep quality was measured by …
Changes In Physical Activity And Relationships To Submaximal Exercise Capacity And Cardiac Function During Breast Cancer Therapy, Moriah P. Bellissimo
Changes In Physical Activity And Relationships To Submaximal Exercise Capacity And Cardiac Function During Breast Cancer Therapy, Moriah P. Bellissimo
Theses and Dissertations
Background: Breast cancer (BC) survivors are at high risk for heart failure due to curative cancer therapies. In non-cancer populations, physical activity is a first line treatment for preventing cardiovascular disease. This study examined whether more physical activity was associated with better submaximal exercise capacity and cardiac function during the first three months of cancer therapy.
Methods: Participants included 223 women with stage I-III BC before therapy and after three months of undergoing treatment and 126 controls. Leisure time physical activity was reported using the Godin Sheppard leisure time exercise questionnaire. Cardiac function was assessed by cardiac magnetic resonance, and …
