Validation of the Turkish Version of QUALEFFO-31

Osteoporosis has become an important public health problem due to low bone mass, decreased bone strength and increased risk of fractures. Today, the measurement of quality of life plays an important role in the approach to diseases. Quality of Life Questionnaire of the European Foundation for Osteoporosis-41 (QUALEFFO-41) has been used for many years as a well-established and fully self-administered questionnaire. In the following years, a shorter and more practical version was needed because the QUALEFFO-41 contains many questions and takes a long time. For this reason, the questionnaire was updated in 2006 and the version of QUALEFFO-31 was made and the validity of the current questionnaire was shown. The aim of this study is to conduct the reliability and validity study of Turkish version of QUALEFFO-31 and to evaluate the power of the questionnaire to distinguish patients with osteoporosis.
