Abstract
This study explored gender differences in mediators and moderators of the association between living alone and psychological distress among 2556 Japanese older adults aged 65 years and older. Putative mediators and moderators were physical health, income, informal networks, and social support. Living alone was significantly related to psychological distress only in men. Significant mediators were income in both genders and social support only in men. Living alone in women was related to having more informal networks, which reduced psychological distress. This contributed to mitigating the effect of living alone on psychological distress among women. Effective moderators were not discovered.
