Ritual homicide during dissociative trance disorder.

A case report is described of a man who developed a single period of recurrent episodes of dissociative trance disorder (DTD) during a family stress. The cultural environment was permeated by thoughts and beliefs in magic. During one trance state, the man performed an exorcism on the 6-month-old baby of his brother-in-law, and the baby died from cerebral hemorrhage. In the 5-year follow-up, no other episodes of DTD developed, and the man is serving an 18-year sentence.

Personality profiles of patients with dissociative trance disorder in Singapore.

This report studies the personality of individuals who suffer from dissociative trance disorder and examines whether the personality profiles could predict the individual's frequency of trance states. A total of 58 cases were given the Eysenck Personality Questionnaire (EPQ) and their personal information harvested from the case notes and through subsequent interviews. The subjects were also reassessed 1 year later to obtain their frequency of trance states. For both sexes, there were lower extraversion scores and higher psychoticism, neuroticism, and lie scores in the sample compared to the Singapore norms. Of the 47 subjects traced, total episodes of trances that occurred over the 1-year period was positively correlated with neuroticism and negatively with extraversion scores. The high lie scores in individuals with dissociative trance disorder could be a reflection of their concern of how others perceive them. The motivation could be that of restoration of self-esteem or "face." The profiles in the EPQ could be used to predict the individual's frequency of trance states. Subjects with personality traits like nervousness, excitability, and emotional instability were more likely to have a higher frequency of trance states.

Dissociative trance disorder: clinical and Rorschach findings in ten persons reporting demon possession and treated by exorcism.

Although dissociative trance disorders, especially possession disorder, are probably more common than is usually though, precise clinical data are lacking. Ten persons undergoing exorcisms for devil trance possession state were studied with the Dissociative Disorders Diagnostic Schedule and the Rorschach test. These persons had many traits in common with dissociative identity disorder patients. They were overwhelmed by paranormal experiences. Despite claiming possession by a demon, most of them managed to maintain normal social functioning. Rorschach findings showed that these persons had a complex personality organization: Some of them displayed a tendency to oversimplify stimulus perception whereas others seemed more committed to psychological complexity. Most had severe impairment of reality testing, and 6 of the participants had an extratensive coping stile. In this group of persons reporting demon possession, dissociative trance disorder seems to be a distinct clinical manifestation of a dissociative continuum, sharing some features with dissociative identity disorder.
