Unpredictable Changes: Different Effects of Derailment on Well-Being Between North American and East Asian Samples

Some individuals experience the feeling that they have become a person they had not anticipated. The life path they had expected to take is not consonant with the one they are taking in reality. This perception of “off-course” in identity and self-direction is referred to as derailment. Although previous studies have postulated and demonstrated that derailment causes a low level of well-being, no studies have examined its existence and effect across cultures. We hypothesized that East Asians (Japanese) are less vulnerable to feeling derailed than North Americans (Canadians/Americans), and that those Japanese who feel derailed do not necessarily experience long-term damage to their well-being. Two correlational studies and one longitudinal study with a one-year interval supported these hypotheses and also demonstrated metric invariance of the Derailment Scale between countries. We discuss that these findings may be explained by East Asian’s dialectical thinking, in which the perception of one’s life direction is flexible.
