Supplementary Material for: The Italian Version of the Severe Respiratory Insufficiency Questionnaire

<b><i>Background:</i></b> The Severe Respiratory Insufficiency Questionnaire (SRI) is a multidimensional instrument for health-related quality of life (HRQL) assessment in patients with chronic respiratory failure (CRF). The SRI has originally been developed in German in 2003, but 15 translated versions have been created during the last 18 years with the exclusion of the Italian translation. <b><i>Aims of the Study:</i></b> The present project was aimed at creating an Italian version of the SRI. <b><i>Methods:</i></b> Professional forward-translation and back-translation procedures have been provided based on the original German version by independent translators, and this was followed by final reconciliation. <b><i>Results:</i></b> The Italian SRI contains 49 items covering 7 different subscales which can summarize to one Summary Score. <b><i>Conclusions:</i></b> The Italian SRI is a multidimensional instrument, which can be used for HRQL assessment in Italian-speaking patients with CRF. Validation of the Italian version of the questionnaire is formally required in the future.

**背景**：重症呼吸功能不全问卷（Severe Respiratory Insufficiency Questionnaire, SRI）是一款用于慢性呼吸衰竭（Chronic Respiratory Failure, CRF）患者健康相关生命质量（Health-Related Quality of Life, HRQL）评估的多维测评工具。该问卷最初于2003年以德语开发完成，近18年间已衍生出15种译版，但意大利语译版始终缺失。
**研究目的**：本项目旨在开发SRI的意大利语译版。
**研究方法**：本研究委托独立译员基于德语原版问卷开展专业正向翻译与回译流程，随后进行最终的共识校准。
**研究结果**：意大利语版SRI共包含49个条目，涵盖7个不同维度量表，所有维度可汇总为一项总评分。
**研究结论**：意大利语版SRI为多维评估工具，可用于意大利语人群慢性呼吸衰竭患者的健康相关生命质量评估。未来仍需对该意大利语译版问卷开展正式的效度验证工作。
