摘要

Objective: This paper aims to determine the reliability and validity of the Chinese version of a tool that assesses the quality of life in idiopathic pulmonary fibrosis (cATAQ-IPF) in patients with interstitial lung disease (ILD).Methods: We used the process of scale introduction to establish cATAQ-IPF.The content validity of the scale was evaluated by six experts.A total of 92 patients with ILD completed the cATAQ-IPF,St.George's respiratory questionnaire (SGRQ),and The Medical Research Council dyspnoea scale at the baseline,and 15 patients completed cATAQ-IPF at the follow-up period 2 weeks later.Thus,yielding data were used to assess various psychometric properties of cATAQ-IPE Intraclass correlation coefficient (ICC),Cronbach's α coefficient,content validity index (CVI),item-level CVI (I-CVI),Pearson's coefficients,criterion-relation validity,and known-group validity were used for data analysis.Results: The cATAQ-IPF showed excellent test-retest reliability (ICC =0.95),except for the therapy domain (Cronbach's α =0.60) and acceptable internal consistency (Cronbach's α =0.96 for the total).The scale-level CVI was 0.80,and the I-CVI was in the range of 0.78-1.00.The total cATAQ-IPF score was strongly correlated with the SGRQ total score (r =0.71,P ＜ 0.01).The cATAQ-IPF score of patients with ILD was 250.74±47.39,and that of patients with IPF was 287.90±22.56.Patients with IPF possessed considerable impairments in health-related quality of life according to the cATAQ-IPF score (t =4.94,P＜ 0.01).Conclusions: The cATAQ-IPF is a reliable and valid instrument for the evaluation of quality of life of Chinese patients with various forms of ILD.
