Life-space mobility (LSM) in older adults is influenced by physical, cognitive, and psychological states. However, the relationship between LSM and personality traits remains unclear. Thus, our cross-sectional study investigated this correlation, which included 144 participants aged ≥60 years. LSM was assessed using the life-space assessment (LSA), and personality traits were evaluated using the Japanese version of the Ten-Item Personality Inventory (TIPI-J). Physical data were also collected. Univariate analyses revealed that among young-older adults, extroversion in the TIPI-J showed a significant association with LSA scores in addition to handgrip strength. Among old-older adults, openness to experience in the TIPI-J demonstrated a significant association with LSA scores in addition to quadriceps strength. This study revealed correlations between personality traits (extroversion and openness to experience) and LSM, in addition to physical function. Considering older adults' personality traits is crucial for designing support and interventions to maintain and expand LSM.
