Summary
AI-generated from the abstractIn 227 adult volunteers, déjà vu experiences occurred in 162 (71.4%) individuals. While initial analysis showed a correlation between déjà vu frequency and dissociative experiences, this link disappeared after accounting for other factors. The strongest predictors of dissociative experiences were age, jamais vu, depersonalization, and precognitive dreams. Déjà vu experiences were not associated with pathological dissociation. The findings suggest that déjà vu is unlikely to be a core pathological dissociative experience.

Abstract
We investigated the relation between déjà vu and dissociative experiences in nonclinical subjects. In 227 adult volunteers, déjà vu and dissociative experiences were evaluated by means of the inventory of déjà vu experiences assessment and dissociative experiences scale (DES). Déjà vu experiences occurred in 162 (71.4%) individuals. In univariate correlation analysis, the frequency of déjà vu experiences, as well as 5 other inventory of déjà vu experiences assessment symptoms and age at the time of evaluation, correlated significantly with the DES score. After exclusion of intercorrelative effects using multiple regression analysis, déjà vu experiences did not remain in the model. The DES score was best correlated with a model that included age, jamais vu, depersonalization, and precognitive dreams. Two indices for pathological dissociation (DES-taxon and DES > or = 30) were not associated with déjà vu experiences. Our findings suggest that déjà vu experiences are unlikely to be core pathological dissociative experiences.
