Indiana University-Purdue University Indianapolis (IUPUI) / Social support has been shown to positively impact various aspects of health across the lifespan, including sexual health and well-being. While past research on sexual well-being has tended to focus on the earlier stages of the life course, notably adolescence and young adulthood, this is a largely ignored area of research past the reproductive stage of life. Current research finds that while social support, from partners, family, and friends alike, has generally positive influences on health in mid to late adulthood, these outcomes are varied in regards to sexual well-being. This thesis aims to (1) assess the role of friend support in the sexual well-being of older adults and (2) to explore if physical and mental health are significant mediators of this relationship, using data from Wave II of the National Social Life, Health, and Aging Project (NSHAP). This study found that sixty two percent of older adults are not having sex as much as they would like and 61% feel that their sex life is lacking in quality. Increased feelings of openness with friends was associated with satisfaction with sexual frequency (p=.055). However, a significant association could not be established between satisfaction with quality of sex life and friend support. In addition, physical and mental health status were not found to be significant mediators.
