Abstract
OBJECTIVE
This study aimed to develop and validate a Japanese version of the Occupational Future Time Perspective scale (OFTP-J) and assess its structural validity, construct validity, internal consistency, and test-retest reliability among Japanese workers.
METHODS
The online survey was conducted with 2046 participants who met the eligibility criteria. The Japanese version of the OFTP scale was developed through translation and back-translation processes. Confirmatory factor analysis was performed to evaluate the structural validity. Pearson's correlations were computed to assess construct validity, and Cronbach's alpha coefficients were calculated to determine internal consistency. Test-retest reliability was examined using Cohen's weighted kappa coefficients and intraclass correlation coefficients.
RESULTS
The confirmatory factor analysis supported an 8-item model with three factors (i.e., focus on opportunities, perceived remaining time, and focus on limitations) for the Japanese version of the OFTP scale. The scale demonstrated high internal consistency, with Cronbach's alpha coefficients ranging from 0.81 to 0.92. Construct validity was supported by significant correlations between the OFTP scale and its subscales, possible antecedents (age, self-rated health, and job control), and possible outcomes (learning goal orientation, job crafting, and work engagement). Test-retest reliability was confirmed with moderate agreement.
CONCLUSIONS
The OFTP-J was found to be reliable and valid. It can be used to measure OFTP among Japanese workers and facilitate comparative research with the original English version. The OFTP-J provides valuable insights into the learning motivation and work engagement of the aging workforce.
