Abstract:The Hypomanic Personality Scale (HPS) is a psychometric assessment that identifies bipolar spectrum psychopathology and risk for bipolar disorders. Despite its conceptualization as a unidimensional scale, several studies have attempted to derive an underlying multidimensional structure of the HPS. Given the lack of consensus between these models, and the interest in elucidating the multidimensional structure of bipolar spectrum psychopathology, we attempted to replicate previous multidimensional models of the HPS with a large undergraduate and adult sample (n = 5002). We were unable to successfully replicate these prior models and derived, instead, two competing models of the underlying factor structure of the HPS. However, these models were limited by factors of unequal sizes and questionable content validity. We examined the associations of our two models with questionnaire and interview measures of affect and psychopathology. Ultimately, we concluded that the HPS is best employed in its original, unidimensional form. We recommend that the creation of a multidimensional assessment of bipolar spectrum psychopathology should follow from the development of a theoretically driven, comprehensive multidimensional model, rather than from parsing apart a useful, but largely unidimensional measure, such as the HPS.
