BACKGROUND: To determine the impacts of different administration modes on sensitivity and specificity of Edinburg Claudication Questionnaire (ECQ) in estimation of Ankle Brachial Index (ABI) detected Lower Extremity Arterial Disease (LEAD).
METHODS: Eligible respondents aged 50 years or older underwent first a self-administered (SA-) ECQ, and then an interviewer-administered (IA-) ECQ. Interviewing included additional guidance on symptoms relevant to claudication. ABI was measured by hand-held Doppler.
RESULTS: A total of 177 respondents (age: 64.67±9.19, male/female: 80/97) were enrolled. Questions 1, 2, 3, and 5 (collectively defines claudication) were responded significantly different on SA-ECQ and IA-ECQ modes. Markings of pain on the figure of ECQ also changed significantly when the procedure was guided. Of the respondents, none on SA-ECQ and 13.6% on IA-ECQ with positive claudication had a low ABI. Subjects with higher formal education level did similar to the whole group in both modes. Sensitivity and specificity of IA-ECQ was calculated as 25% and 88.5%, respectively, for ABI detected LEAD.
CONCLUSIONS: Respondents’ perceptions on pain, discomfort, exertion or body regions described on ECQ may subject to errors without guidance. ECQ seems reliable in evaluating claudication when only specifically interviewed by an observer.
