Early-life traumatic experiences have lasting implications for late-life socio-emotional development, contributing to a greater prevalence of poor mental health in very old age. The purpose of this study was to examine the influence of early-life and recent traumatic life experiences on loneliness among centenarians. A total of 154 centenarians participated in a semistructured interview. The time of traumatic occurrence and type of trauma experienced influence loneliness in centenarians. Experiencing a natural disaster 70 or more years ago significantly predicted loneliness. Terror management theory proposes that coming to terms with one's mortality represents an underlying source of anxiety that can influence human behavior to create both immediate and future defenses. Evidence from this study can be used to improve how aging service practitioners integrate reminiscence or life-review therapy or counseling within clinical or educational settings.
