Abstract
PURPOSE: The purpose of the study was to test the psychometrical properties of the Chinese version of the Pulmonary Embolism Quality of Life (PEmb-QoL) questionnaire. METHODS: We translated the English version of the PEmb-QoL into Chinese. Patients at various periods after pulmonary embolism diagnosed at Peking Union Medical College Hospital between May 2016 and Dec 2017 were invited to complete the questionnaire. Standard psychometrical tests and criteria were used to evaluate the acceptability, reliability and validity of the Chinese version of the PEmb-QoL. RESULTS: A total of 108 participants completed the questionnaire and were included for further analysis. The Chinese version of the PEmb-QoL showed good internal consistency (Crohnbach's alpha ranging from 0.643 to 0.930), inter-item correlations (0.369-0.599), and item-total correlations (0.341-0.893). Test-retest reliability was also good (0.759-0.896). Moderate correlations between PEmb-QoL and SF-36 dimensions, and low correlations between PEmb-QoL and clinical characteristics supported convergent and discriminant validity. Exploratory factor analysis suggested four underlying dimensions: work-related problems, daily activity limitations, emotional complaints and frequency and intensity of complaints. CONCLUSIONS: The Chinese version of the PEmb-QoL questionnaire is both valid and reliable for measuring quality of life in patients at various periods after pulmonary embolism, proving the universality of this disease-specific questionnaire.
