A disinhibited temperament may underlie a behavioral impulsivity that contributes to elevated risk for future alcoholism, especially among FH+ males.

Thirteen patients with dissociative identity disorder (DID), 13 with other mental disorders, and 10 nondiagnosed comparison participants were given individual grids. Results showed that displaying alternate personalities did not portend a more multidimensional level of thinking. Instead, the nonclinical comparison group had the greater degree of complexity in comparison to both clinical groups. A notable clinical observation was that DID patients, as compared to non-DID participants, had a greater understanding and speed in completing the grid. Findings are discussed in terms of the advantages of personal construct theory for conceptualizing the construct of dissociation.
