In a study of 98 cases of deliberate self harm, a high correlation was obtained between a diagnosis of Major Depressive Disorder (M.D.D.) and scores on both the Hamilton Rating Scale for depression (HRS) and the Suicide Intent Scale (SIS). There was also a high correlation between HRS and SIS scores. A higher score on HRS and SIS correlated with increasing age, as also did a diagnosis of M.D.D.
