The Clinically Useful Depression Outcome Scale

The Clinically Useful Depression Outcome Scale

(CUDOS)
(Zimmerman, Chelminski, McGlinchey, & Posternak, 2008)

The CUDOS can be used as a screening tool, a diagnostic tool (Zimmerman et al., 2008), and to monitor symptom changes over time (Zimmerman, McGlinchey, & Chelminski, 2008). The CUDOS has not been used with adolescents, nor does a separate adolescent version exist. The CUDOS is an 18-item self-report measure assessing depressive symptoms in adults.

Sample items include,
“I felt sad or depressed,” 
“I was not as interested in my usual activities,” and “I felt guilty.”

Each item is rated on a 5-point Likert scale indicating from zero (“not at all true/0 days”) to four (“almost always true/every day”). Total scores range from 0 to 64. The CUDOS was designed to be completed in less than three minutes and scored in less than 15 seconds. The CUDOS demonstrates excellent internal consistency (α = .90) and adequate test-retest reliability over a period of one week (r > .92; Zimmerman et al., 2008). In addition, the CUDOS demonstrates concurrent validity with the BDI (Beck et al., 1961) and the Hamilton Rating Scale for Depression (Hamilton, 1960). The measure is available online (http://www.outcometracker.org).
