Dissociative experience in hypothetically psychosis-prone college students.
The relationship between dissociative experiences and psychosis proneness was investigated in a sample of 523 college undergraduates. Participants were administered the Dissociative Experiences Scale (DES), the Perceptual Aberration Scale, the Magical Ideation Scale, the Social Anhedonia Scale, and the Physical Anhedonia Scale. As hypothesized, the Perceptual Aberration and Magical Ideation Scales were positively correlated with the DES. The Social Anhedonia Scale had a modest correlation with the DES, but this relationship was largely mediated by the Perceptual Aberration and Magical Ideation Scales. The Physical Anhedonia Scale was uncorrelated with the DES. Exploratory factor analysis of the psychosis-proneness scales and the DES subscales resulted in a three-factor solution: dissociative experiences, positive schizotypy, and negative schizotypy. The DES depersonalization subscale loaded on both the dissociation and positive schizotypy factors.
