24 physicians in Southampton university hospitals were randomly divided into a group who used a questionnaire developed to help assess 150 patients who took overdoses & another group who asked questions they felt appropriate. After the physician’s assessment, a research assistant interviewed all of the patients & the 2 assessments were compared. There was greater agreement between the research assistant & the physicians using the questionnaire than those who used unstructured interviews.
