This study examined the effects that status of interpersonal stressors and frequency of interpersonal stressors have on the experience of symptoms of depersonalization, including the factor of mental health status. A questionnaire survey was administered to 364 university students, and the results demonstrated that the frequency of interpersonal stressors had an effect on the students' experiences of symptoms of depersonalization. It was also demonstrated that a higher frequency of interpersonal conflict as a stressor significantly increases the experience of symptoms of depersonalization called "uncomfortable feeling for body sensation and others" for the group with lower mental health status, when compared to the group with higher mental health status. Because interpersonal conflict has a stronger impact on the individual compared to interpersonal dislocation and interpersonal failure, it can be estimated that people with a lower mental health status perceive it more intensely, and that it can become a strong stressor. Furthermore, it was suggested that the frequency of interpersonal dislocation can become a trigger for an experience of symptoms of depersonalization present with an uncomfortable feeling for self, and the frequency of interpersonal conflict can become a trigger for an experience of symptoms of depersonalization present with an uncomfortable feeling for the external world.
