The psychological scars of suicide: Accounting for how risk for suicidal behavior is heightened by its past occurrence

Publication date: Available online 24 January 2019Source: Neuroscience & Biobehavioral ReviewsAuthor(s): Richard T. LiuAbstractNot only is suicidal behavior strongly predicted by its past occurrence, but the risk for recurrence appears to increase with each subsequent attempt. The current paper discusses a potential explanation for this phenomenon, that suicide attempts may leave a residual psychological scar that heightens risk for future attempts. This possibility is evaluated against two alternatives: (i) risk for first and subsequent suicide attempts is accounted for by a shared diathesis pre-existing the first lifetime attempt, and (ii) different rates of developmental decline in risk factors account for differences in prospective number of attempts. In this discussion, a formalized conceptual framework of psychological scarring is presented, along with considerations of particular relevance to its study. Finally, the clinical implications of determining the processes underlying the association between suicide attempts and heightened risk for recurrence are discussed.
