ABSTRACT
STUDY DESIGN:
Prospective observational study.OBJECTIVE:
The population of patients with advanced stages of cancer, including metastatic spinal disease, is growing because of better treatment options allowing for longer control of disease. The main goal of treatment for these patients is to improve or maintain their health-related quality of life (HRQOL). A spine oncology-specific outcome measure has been developed by the Spine Oncology Study Group and validated through international studies. We proposed to translate and validate the questionnaire in Italian language.METHODS:
The cross-cultural adaptation of the questionnaire has been performed according to guidelines previously proposed. After this process, an observational prospective study has been conducted to validate the efficacy of SOSGOQ in Italian language. SOSGOQ has been compared to SF-36 (Short Form Health Survey-36), a generic validated questionnaire to assess HRQOL. Starting from January 2020, SOSGOQ and SF-36 questionnaires were auto-administered to 150 patients affected by spinal metastases who provided written informed consent for study participation.RESULTS:
The confirmatory factor analysis on the 4 domains examined showed a good model fit (comparative fit index, .95; RMSEA .07 (90% CI, .05-.09) and SRMR, .05), endorsing construct validity. The analysis of concurrent validity demonstrated strong correlation for physical function, pain and mental health domains with the corresponding domain scores of SF-36. The reliability across item was high with a Cronbach's alpha coefficient of .91.CONCLUSIONS:
The statistical analysis of the results will allow to accept the Italian version of SOSGOQ as a specific and efficient tool to measure HRQOL in Italian-speaking patients affected by spinal metastases.
