Time Perception Scale: Measurement invariance between the United States and Japan.

The Time Perception Scale (Niiya, 2019, Journal of Happiness Studies) measures people's perception of time as zero‐sum (i.e., the perception that they are taking time away from others, that they are offering time to others, or that others are taking away time from them) and nonzero‐sum (i.e., the perception that time spent on others is time spent on themselves). This scale was validated in Japan, but whether people from a non‐Asian culture also perceive time as nonzero‐sum remained unknown. We tested the measurement invariance of the Time Perception Scale with 189 Americans and 240 Japanese and examined its correlations with psychological well‐being and cultural self‐construals. We confirmed the configural, metric, and partial scalar invariance of the scale and also found that zero‐sum and nonzero‐sum time perceptions were differently associated with basic needs satisfaction, life satisfaction, and interdependent self‐construal in both cultures. Nonzero‐sum time perception may provide a new possibility where a concept derived from East Asian philosophy can contribute to our psychological well‐being. [ABSTRACT FROM AUTHOR]
