Quality of Life Assessment with ICQ

The ICQ contained 16 questions about the severity of the problem, severity of symptoms, and the impact of intermittent claudication on the patient’s daily life. The answers were scored in the range from 0 to 5 points, and then summed. A higher score indicated a significant severity of the problem and greater limitations caused by intermittent claudication. The total sum of the test scores ranged from 0 (indicating good quality of life) to 80 (indicating poor quality of life). The final results were converted into percentages, where the maximum score was 80 points (meant 100%). The questionnaire contained written instructions for the patients to answer the questions on their own. Before returning the questionnaires, the completeness of the answers provided by the patients was checked. Only completely and correctly completed questionnaires were included in the final analysis.
