The Hamilton Rating Scale for Depression (HRSD),[1] also called the Hamilton Depression Rating Scale (HDRS), sometimes also abbreviated as HAM-D, is a multiple-item questionnaire used to provide an indication of depression, and as a guide to evaluate recovery.[2]Max Hamilton originally published the scale in 1960[3] and revised it in 1966,[4] 1967,[5] 1969,[6] and 1980.[7] The questionnaire is designed for adults and is used to rate the severity of their depression by probing mood, feelings of guilt, suicide ideation, insomnia, agitation or retardation, anxiety, weight loss, and somatic symptoms.
The HRSD has been criticized for use in clinical practice as it places more emphasis on insomnia than on feelings of hopelessness, self-destructive thoughts, suicidal cognitions and actions.[8] An antidepressant may show statistical efficacy even when thoughts of suicide increase but sleep is improved, or for that matter, an antidepressant that as a side effect increase sexual and gastrointestinal symptom ratings may register as being less effective in treating the depression itself than it actually is.[9] Hamilton maintained that his scale should not be used as a diagnostic instrument.[10]
The original 1960 version contained 17 items (HDRS-17), but four other questions not added to the total score were used to provide additional clinical information. Each item on the questionnaire is scored on a 3 or 5 point scale, depending on the item, and the total score is compared to the corresponding descriptor. Assessment time is about 20 minutes.
