Description: | The Clinically Useful Depression Outcome Scale (CUDOS) is a brief, quickly scored, self-report scale used to assess depressive symptoms over the past 1 week. CUDOS is reliable, valid, and sensitive to change.1 The CUDOS consists of 18 questions. The first 16 are scored from 0 to 4 for frequency of symptoms over the past week. The final 2 questions cover the impact of these symptoms on the respondent’s life and their overall quality of life in the past week.2 |

Detailed Description: | The CUDOS is a self-report scale used to assess for depressive symptoms over the past 1 week.1,2 One characteristic that may make the CUDOS attractive for use in clinical practice is its brevity. Additionally, the CUDOS thoroughly covers the diagnostic criteria for MDD as laid out in the Diagnostic and Statistical Manual of Mental Disorders (DSM). It does not require purchase, and it is simple to score.1 The authors recommend CUDOS scoring as follows: scores of 0 to 10 correspond to nondepressed; scores of 11 to 20 correspond to minimal depression; scores of 21 to 30 correspond to mild depression; scores of 31 to 45 correspond to moderate depression; and scores of 46 and higher correspond to severe depression.1 |
Scale Validity: | A large validation trial was completed in 2008.1 The sensitivity of the scale is 83.3%, and the specificity of the scale is 72.1%. The scale has a positive predictive value of 72.6% and a negative predictive value of 82.9%.1 |
Alternative Versions: | CUDOS-D (daily),4 CUDOS-M (mixed)5 |
Cited Limitations: | Limitations with self-report questionnaires in general include the possibility of the respondent answering falsely or incorrectly to an item or items as well as the ability of the respondent to read and understand the scale.1 Additionally, the CUDOS assesses symptom severity in terms of frequency only, while some scales consider both symptom frequency and intensity (eg, the Quick Inventory of Depressive Symptomatology–Self-Report [QIDS-SR]).6 |
