title: Psychophysiological correlates of 'bipolarity'.
abstract: Four hundred patients with major affective disorders were divided into six groups based on lifetime composite evaluations of the intensity, frequency, and duration of their high energy-positive mood states. This division was termed degree of 'bipolarity'. Within the non-bipolar I patients (groups 1-4) the rating of 'bipolarity' was found to be significantly positively associated with enuresis, classical migraine, Raynaud's disease, learning disorders, fingernail biting, and episodic phenomena. The possible significance of this non-bipolar I 'bipolarity' continuum construct is discussed. A significant discontinuity was found between 'bipolarity' groups 5/6 and group 4 in six of the 14 psychophysiologic conditions evaluated.
