Non-heterosexual populations experience poorer mental health outcomes than their heterosexual counterparts. Few studies, however, have examined how mental health varies across the continuum of sexual orientation. Nor has any study examined possible links between sexual orientation and traits of impulsivity and compulsivity, which contribute to functional impairment across a broad spectrum of psychiatric disorders. To address these limitations, the present study sought to identify addictive and impulsive/compulsive problems associated with sexuality in a university sample.
