解離と外傷体験の関連性に関する動向と展望 : 解離の発現因をめぐって

The goal of this research is to review the correlation between dissociation and traumatic events and to clarify topics for future discussion. If we consider the background of dissociation studies, we see that dissociation has generally been assumed to have a strong correlation with traumatic events. However, prior research indicates that the correlation may be weaker. A theoretical dissociation framework is thus needed that accounts for dissociation caused by non-traumatic events as well as traumatic events that do not cause dissociation. To construct such a theory, we must (1) combine the correlation established in prior research between dissociation and events to obtain an established view, (2) clarify which characteristics of both traumatic and non-traumatic events are more likely to cause dissociation, (3) examine how individuals perceive events. Most contemporary dissociation research is quantitative, but we anticipate improvements in qualitative research that will enable examination of subjective variables of individual perception.
