OBJECTIVE: The most validated health-related quality-of-life (HRQOL) questionnaire specific to the metastatic spine cancer population is the Spine Oncology Study Group Outcomes Questionnaire version 2 (SOSGOQ2.0). The purpose of this study was to translate and validate a Russian version of the SOSGOQ2.0.

METHODS: The SOSGOQ2.0 was translated into Russian and cross-culturally adapted. In this study, 64 eligible patients completed the SOSGOQ2.0_RUS along with the EQ-5D 5 Level, SF-36 quality-of-life questionnaires, and visual analog scale for pain assessment scale (VAS). Internal consistency was measured using Cronbach's alpha, in which a score of 0.65 or higher is acceptable. Test-retest reliability was evaluated by examining the intraclass correlation coefficient (ICC).

RESULTS: Included in this study were 64 Russian-speaking patients (median age 59 years) with metastatic spine disease. The most common primary tumors were breast, kidney, and prostate cancers. The overall Cronbach's alpha was 0.87, indicating high internal consistency. The overall ICC for the SOSGOQ2.0_RUS was 0.88 (95% CI 0.81-0.93), indicating high reliability and consistency of the measure. The physical function, pain, and mental health domains of the SF-36 moderately correlated with the same domains of the SOSGOQ2.0_RUS, with correlation coefficients ranging from 0.65 to 0.71.

CONCLUSIONS: The SOSGOQ2.0_RUS is a reliable and valid questionnaire for assessing the HRQOL in patients with metastatic spinal tumors. The questionnaire showed high internal consistency, test-retest reliability, and good construct validity when compared with other established questionnaires.
