Polish version of the Intermittent Claudication Questionnaire
Abstract
Introduction. The assessment of health-related quality of life includes the assessment of physical condition and motor skills, mental condition, social and economic situation, and somatic experiences. The specific ques-tionnaires used in patients with intermittent claudication include i.a. Peripheral Artery Questionnaire, Vascular Quality of Life Questionnaire, PAD Quality of Life Questionnaire, and Walking Impairment Questionnaire, which is the only one of the aforementioned questionnaires that is available in Polish. The Intermittent Claudication Questionnaire (ICQ) available in English is a specific instrument for assessing the quality of life of patients with intermittent claudication. This paper attempts at evaluating the reliability of the Polish version of ICQ.
Material and methods. The process of validation of the Polish version of the questionnaire involved translating the questionnaire and evaluating the newly translated tool in order to compare the results on international level for the possibility of its practical use for assessment of health-related quality of life in patients with intermittent claudication in Poland. In order to evaluate the reliability and coherence of the questionnaire, the methods of internal consistency in Cronbach’s a, as well as the intraclass correlation coefficient were applied for specific questions and for the final result of the questionnaire.
Results. The Cronbach’s a as the questionnaire’s reliability index was 0.915. Intraclass correlation calculated for the total score of the questionnaire’s answers was 0.97.
Conclusions. The Polish version of the Intermittent Claudication Questionnaire is a repeatable and reliable research tool for assessing the health-related quality of life in patients with intermittent claudication.
