Testing Shneidman’s model of suicidality in incarcerated offenders and in undergraduates

Suicidality constitutes a major health issue for society in general and incarcerated populations in particular. Shneidman’s model of suicide proposes that psychache (i.e., intense psychological pain) is the pre-eminent psychological cause of suicidality and mediates the influence of all other psychological correlates such as depression or hopelessness. The current research evaluates Shneidman’s model for samples of 73 male federal offenders, 80 male undergraduates, and 80 female undergraduates. Consistent with Shneidman’s theory, psychache was both a significant and a more important statistical predictor of reported self-harming ideation and action than was either depression or hopelessness. Further, this relatively greater importance of psychache for the statistical prediction of suicidality was not moderated either by offender status or by sex. Overall, findings support the applicability of Shneidman’s model of suicidality to incarcerated individuals and indicate the model’s generalizability across sex and offender status.
