Aim: The aim of this study was to report preliminary validation data on the Polish version of the International Osteoporosis Foundation Quality of Life Questionnaire (IOF QLQ) for patients with a distal radius fracture (DRF).
Materials and methods: Patients were eligible if they were between 18-80 years and were within 1-3 days after a non-comminuted DRF. All patients filled out the Polish version of the IOF QLQ, the Short Form 36 (SF-36) and a demographic questionnaire. Assessment points were set as soon as possible after the fracture, 7 days, 6 weeks, and 3 months after the fracture. Standard va- lidity and reliability analyses were performed.
Results: Fifty-eight patients (42 women - 72.4%) agreed to take part in the study (mean age of the group 65.7 ± 9.3 years). Cronbach's alpha coefficients showed positive internal consistency (0.82- 0.87). The interclass correlations for the IOF QLQ domains and the overall score ranged from 0.82 to 0.93. Satisfactory convergent and discriminant validity of the IOF QLQ was seen.
Conclusions: Preliminary data show that the Polish version of the IOF QLQ for patients with a DRF is a reliable and valid tool for measuring health-related quality-of-life (HRQoL). However, further studies are needed to demonstrate the full psychometric and clinical properties of the IOF QLQ in patients with a fracture of the wrist.
