Quantitative EEG was used to assess the intra-personal variability of brain electrical activity for 3 women diagnosed with Multiple Personality Disorder (MPD). Two separate control groups (within-subject and between-subject) were used to test the hypothesis that the intra-personal EEG variability between 2 alters would be less than the interpersonal EEG variability between 2 controls, and similar to the intra-personal EEG variability of a single personality. This hypothesis was partially supported. In general, the 2 EEG records of a MPD subject (alter 1 vs. alter 2) were more different from one another than the 2 EEG records of a single control, but less different from one another than the EEG records of 2 separate controls. Most of the EEG variability between alters involved beta activity in the frontal and temporal lobes.
The clinical and demographic data of 664 youth (M age ϭ 13.92, SD ϭ 2.58) were used to identify factors associated with frequent use of psychiatric hospitalization. Clinical data included scores on the Self-Report of Personality (SRP) and Parent Rating Scales (PRS) of the Behavior Assessment System for Children, Second Edition (BASC-2). Demographic data included age, race/ethnicity, gender, and the presence or absence of surrogate care. Results indicated that those youth with frequent admissions to the hospital were generally between 13 and 18 years old ( p ϭ .01), African American ( p ϭ .03), and in surrogate care ( p ϭ .04). Relative to the other youth in our sample they were more aggressive ( p Ͻ .001) and hyperactive ( p Ͻ .001) with severe conduct problems ( p Ͻ .001). They also had more difficulty adapting to change ( p ϭ .003). The implications of these findings and the recommended interventions for youth with disruptive behaviors are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
