The Rorschach Suicide Constellation: assessing various degrees of lethality.
In this article we examine the relation between the Rorschach Comprehensive System's Suicide Constellation (S-CON; Exner, 1993; Exner & Wiley, 1977) and lethality of suicide attempts during the course of patients' hospitalization at the Austen Riggs Center (Stockbridge, MA). Patient records were rated as nonsuicidal (n = 37), parasuicidal (n = 37), or near-lethal (n = 30) based on the presence and lethality of self-destructive acts. Diagnostic efficiency statistics utilizing a cutoff score of 7 or more positive indicators successfully predicted which patients would engage in near-lethal suicidal activity relative to parasuicidal patients (overall correct classification rate [OCC] = .79), nonsuicidal inpatients (OCC = .79), and college students (OCC = .89). Although these predictions were influenced by relatively high base rates in the hospital population (14.5%), base rate estimates were calculated for other hypothetical populations revealing different prediction estimates that should be considered when judging the relative efficacy of the S-CON. Logistic regression analysis revealed that an S-CON score of 7 or more was the sole predictor of near-lethal suicide attempts among 9 psychiatric and demographic variables.
