Self-transcendence is a personality trait associated with experiencing spiritual ideas such as considering oneself an integral part of the universe. It is one of the "character" dimensions of personality assessed in Cloninger's Temperament and Character Inventory. Self-transcendence is distinctive as the first trait concept of a spiritual nature to be incorporated into a major theory of personality. High self-transcendence has been linked to psychotic tendencies, such as schizotypy and mania, particularly in individuals low in both self-directedness and cooperativeness. Although there has not been a great deal of research into the validity of self-transcendence as a measure of spirituality, one study found that self-transcendence was significantly related to a number of areas of belief and experience that have been traditionally considered "spiritual".
