Hypomanic personality traits: A multi-method exploration of their association with normal and abnormal dimensions of personality

This study reports on a multi-method examination of the associations between the Hypomanic Personality Scale (HPS) and a number of normal and abnormal personality traits. An unselected sample of undergraduates (N = 101) participated in structured laboratory tasks assessing Big Five traits, completed self-report measures of Big Five and other personality traits, and for a subset of participants, informant-reports of these traits were also collected. HPS scores were associated with measures tapping higher Extraversion and Openness, and lower Conscientiousness/Constraint. The pattern of correlates was consistent across method, and there was evidence for unique associations between the HPS and various traits, as well as incremental validity of laboratory measures.
