Abstract: The Depression Hopelessness Suicide Screening Form (DHS) includes twelve “critical items”, which have not been validated for the prospective prediction of self-harm. We conducted a retrospective cohort study (N = 4196) to validate the ability of the DHS critical items to predict inmates who performed at least one incident of self-harm during the first six months of imprisonment. While the critical items were highly sensitive (89.5%) at predicting incidents of self-harm, 51.3% of inmates endorsed at least one item. Five items reflecting more recent and specific risk factors reduced the referral rate to 17.7%, while maintaining high sensitivity (84.2%). While the DHS has high sensitivity to predict inmates at risk of self-harm, treating all items as equally critical results in excessive numbers of false positives that likely exceed the capacity of prison resources for professional assessment and intervention. Referral rules based on recency and specificity of risk factors are proposed.
