Several alternative measurement scales or survey instruments have been used to arrive at numerical scores for quality of life. These include the activity status index developed at Duke University (Durham, North Carolina), which assesses physical function; the London School of Hygiene and Tropical Medicine questionnaires for angina and dyspnea; the Medical Outcomes Study short form general health questionnaire; the Quality of Well-being Scale; the sickness impact profile; and several others. Most are variations on the theme of asking specific questions about what people can do and how they feel about it, in relation to the presence or absence of specific symptoms.
