Suicide Intent and Accurate Expectations of Lethality: Predictors of Medical Lethality of Suicide Attempts.

The degree of intent to commit suicide and the severity of self-injury were examined in individuals (N = 180) who had recently attempted suicide. Although a minimal association was found between the degree of suicide intent and the degree of lethality of the attempt, the accuracy of expectations about the likelihood of dying was found to moderate the relationship between suicide intent and lethality. Specifically, higher levels of suicide intent were associated with more lethal attempts but only for those individuals who had more accurate expectations about the likelihood of dying from their attempts.
