Validation assessment of the Chinese version of the Snore Outcomes Survey.
The aim of this study was to use a parallel model to translate the Snore Outcomes Survey (SOS) into Mandarin Chinese language by comparing performing characteristics and statistical properties of the original and Chinese versions SOS. The Chinese version SOS (CSOS) was validated in a prospective, non-randomized manner. A total of 359 patients with sleep-disordered breathing (SDB) aged 18 years and older diagnosed as having SDB participated in the study at entry. Reliability, validity, and longitudinal sensitivity data for CSOS were obtained. CSOS demonstrated good test-retest reliability (Intra-class correlation coefficient = 0.751). The Cronbach's alpha coefficient was 0.86. The item-total correlation coefficients varied from 0.30 to 0.99. The CSOS correlated well with polysomnogram (PSG) parameters including respiratory distress index (RDI), lowest arterial O2 saturation (LAST). CSOS also yielded significant correlations with vitality subscale of Chinese Taiwan version SF-36 (r = 0.4, p = 0.0011). The standard response mean (SRM) for CSOS was 1.33. The validation demonstrated only minor effects of language; the statistical properties of the CSOS were equivalent to the English version. The CSOS is a valid tool to evaluate adults with SDB among Chinese-speaking population.
