title: Manic-depressiveness and its correlates.
abstract: Manic-depressiveness is the name here given to a hypothesized personality continuum that has, at one extreme, manic-depressive psychosis. A Manic-Depressiveness Scale is described, which comprises three scales, Manic Experience, Depressive Experience, and the sum of the two, since they are correlated. 250 undergraduate psychology students at the University of Adelaide and at Goldsmiths' College, London, were administered the Manic-Depressiveness Scale along with 12 measures including the Eysenck Personality Questionnaire (Revised). Scores on the total Manic-Depressiveness Scale tended (in order of size of association) to be correlated with Schizotypal Personality (and three subscales), Neuroticism, Magical Ideation, Mystical Experience, Belief in the Paranormal, absence of Social Naïveté, and Psychoticism. Manic Experience showed a pattern of relationships with the above variables broadly similar to that of Depressive Experience but included Creative Personality, while Depressive Experience included introversion. The relationship between manic-depressiveness and schizotypy is discussed.
