Spine Oncology Study Group Outcome Questionnaire
The SOSGOQ includes all domains relevant for measurement of function and disability and its content validity is confirmed by linkage with the International Classification of Function and Disability ICF. This new questionnaire has superior content capacity to measure disease burden of patients with spine metastases than any instruments previously identified in the literature 1).
A study proposes a scoring methodology -after reversing 4 inversely scored items- for the SOSGOQ and demonstrates that the questionnaire is a valid tool for the assessment of quality of life in patients with metastatic spine disease. The SOSG-OQ is superior to the EQ-5D in terms of coverage and internal consistency, but consists of more questions 2).
