Life Events and Loneliness Among Older Women of Diverse Sexual Identities: Application of the Stress Process Model

Abstract

Loneliness among older adults has been a topic of interest in recent years. We analyse four waves of data from the Australian Longitudinal Study on Women’s Health. We estimate growth models to examine differences in loneliness trajectories from age 50 for women who identify as exclusively heterosexual, plurisexual (bisexual, mainly heterosexual, mainly lesbian) and exclusively lesbian. We find no significant differences in levels of loneliness across sexual identity groups at age 50. We find that while loneliness trajectories of exclusively heterosexual women trend down, levels of loneliness increase with age among plurisexual women. Adverse health events and relationship problems increase loneliness to a greater extent among plurisexual women compared to exclusively heterosexual and exclusively lesbian women. Our results suggest older lesbian women may have accumulated social or personal resources or developed coping mechanisms over the courses of their lives, while plurisexual women remain a vulnerable group.
