Abstract: | This study explores the concept of “third culture,” which has not been tested by quantified measures since it was introduced. This study develops the 10-item measurement of third culture based on three dimensions—equality, commonality, and transcendence. Two hundred and fifteen international married individuals from 42 countries participated in a self-administered email survey. The findings indicated that the new scale is reliable and functions as a single dimension instead of as three subdimensions. Suggestions for future study as well as several implications on theory and methodology are discussed, drawing on the experience of this study. |
