The Interpersonal-Psychological Theory of Suicide in College Student Suicide Screening.

Abstract

Suicide screening on campus is limited by effectiveness of existing questionnaires. This study tests whether Interpersonal-Psychological Theory of Suicide (IPTS) constructs may be more effective in screening than traditional risk factors measures like the Interactive Screening Protocol (ISP). Participants were 188 traditional-age students from three different campuses recruited through a subject pool and peer recruiters. IPTS risk variables as a set explained all likelihood of higher risk responses to suicidality questions that was otherwise explained by risk factors, plus additional likelihood besides. Current IPTS measures are no screening "magic bullet," but further inquiry into use of these constructs is warranted.
