Validation of the Japanese Version of the Modified Balanced Time Perspective Scale: Factor Structure, Reliability, and Validity Results1

要旨

Abstract A balanced time perspective (BTP) is defined as a frequent and equal tendency to think positively about both one's past and future. A BTP is related to greater psychological well‐being, such as life satisfaction and wisdom, and these BTP associations may vary cross‐culturally, although few studies of BTP in non‐Western countries exist. In order to advance cross‐cultural comparisons of BTP, an important methodological step is to validate BTP measures in different cultures. This study aimed to develop and validate a Japanese version of the modified Balanced Time Perspective Scale (mBTPS). Japanese participants ( N = 1,020, aged 18–79 years) completed the mBTPS‐J, along with Japanese versions of the Zimbardo Time Perspective Inventory (ZTPI‐J) and measures of well‐being (life satisfaction and wisdom scales). Factor analysis of the mBTPS‐J resulted in a 27‐item mBTPS‐J consisting of Past, Present, and Future subscales. Correlations between the relevant mBTPS‐J and ZTPI‐J subscales, and with the well‐being measures, supported both convergent and predictive validity, respectively. The demonstrated psychometric strengths of the mBTPS‐J will allow for specific testing of important cross‐cultural questions.
