Abstract

Objectives The purpose of this study was to provide normative data of middle-aged and older adults for the Japanese version of the Ten-Item Personality Inventory (TIPI-J), based on the Big Five model of personality (Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness).Methods We surveyed a random sample of community-dwelling middle-aged and older Japanese adults (aged 60-84 years, N=1,200, response rate: 70.8%) and used data from 776 participants (368 men and 408 women). We used the TIPI-J as a measure of the Big Five model of personality comprising ten items, which were measured on a seven-point Likert-type scale. We also assessed the socio-economic and health variables to describe the basic characteristics of participants.Results Standard psychometric methods showed a near-normal score distribution across all subscales; there were significant sex differences in Neuroticism and Openness, and there was no significant difference with respect to age.Conclusion This study provided a grand total table and normative data for the TIPI-J, and examined gender- and age-based differences in the TIPI-J among middle-aged and older adults using data from the general population of Japan. In the future, factors associated with the TIPI-J scores and predictive validity of the scale for health outcomes as external criteria should be examined to test the scale's usefulness for epidemiological surveys among middle-aged and older adults in community settings.

Keywords: Big Five model of personality; middle-aged and older adults; the Japanese version of the Ten Item Personality Inventory (TIPI-J).
