Zung Depression Score
Please visit this website for more information about the instrument:  
Exploratory: Chiari I Malformation (CM)
Short Description of Instrument
Patient-reported outcome instrument addressing affective, psychological and somatic issues in patients with depression.
Zung survey consists of 20 items; 1-A little of the time, 2-Some of the time, 3-A good part of the time, 4-Most of the time. Patients are said to have depression if their Zung Depression score is =50.
Consult the key for the value (1–4) that correlates with patients' responses to each statement. Add up the numbers for a total score. Most people with depression score between 50 and 69. The highest possible score is 80. Range 20–80.

About 6.7% of U.S. adults suffer at least one major depressive episode annually. Depression rates increase in patient groups with disabling symptoms, such as Chiari I malformation, with or without syringomyelia. Recording the Zung Depression Score in patients with Chiari I malformation will allow studies to report the proportion of patients they enroll with the co-morbidity of depression. Additionally, surgical studies that include this standard and replicable instrument can compare the effects of different surgical procedures for Chiari I malformation on depression severity.
