Objective The Depression Interview and Structured Hamilton (DISH) is a semistructured interview developed for the Enhancing Recovery in Coronary Heart Disease (ENRICHD) study, a multicenter clinical trial of treatment for depression and low perceived social support after acute myocardial infarction. The DISH is designed to diagnose depression in medically ill patients and to assess its severity on an embedded version of Williams’ Structured Interview Guide for the Hamilton Depression scale (SIGH-D). This article describes the development and characteristics of the DISH and presents a validity study and data on its use in ENRICHD. Methods In the validity study, the DISH and the Structured Clinical Interview for DSM-IV (SCID) were administered in randomized order to 57 patients. Trained interviewers administered the DISH, and clinicians administered the SCID. In ENRICHD, trained research nurses administered the DISH and recorded a diagnosis. Clinicians reviewed 42% of the interviews and recorded their own diagnosis. The Beck Depression Inventory (BDI) was administered in both studies. Results In the validity study, the SCID diagnosis agreed with the DISH on 88% of the interviews (weighted κ = 0.86). In ENRICHD, the clinicians agreed with 93% of the research nurses’ diagnoses. The BDI and the Hamilton depression scores derived from the DISH in the two studies correlated 0.76 (p < .0001) in the validity study and 0.64 (p < .0001) in ENRICHD. Conclusions These findings support the validity of the DISH as a semistructured interview to assess depression in medically ill patients. The DISH is efficient in yielding both a DSM-IV depression diagnosis and a 17-item Hamilton depression score.
