Reliability of the Terry: a mental health cartoon-like screener for African-American children.

Test-retest reliability and internal consistency of the Terry, a cartoon-based child mental health screener developed for African-American children, were measured in 36 boys (age 5 1/2 to 13) in a test-retest design. Reliability of the diagnosis (0.70 < or = k < or = 0.75) was good for ADHD, ODD, CD, and OAD, and excellent for MDD and SAD. Because of low base-rate, no kappa value was calculated for SPh. Both test-retest agreement, and reliability of the symptom scale (0.75 < or = ICC < or = 0.80) were very good for all 7 diagnoses. Internal consistency according to symptom scale (0.78 < or = Cronbach alpha < or = 0.90), was moderate for OAD, good for SPh, MDD, SAD, CD, and ODD, and excellent for ADHD. The Terry is a culturally-sensitive questionnaire with good reliability.
