Objective To translate the Breathlessness Catastrophizing Scale （BCS） into Chinese, and to test its reliability and validity in COPD patients.Methods Following the Brislin translation model, the Chinese version of the BCS was developed through forward and backward translation, cultural adaptation, and pilot test.Then, a convenience sample of 330 COPD patients attending outpatient clinics at 5 hospitals in Suzhou were surveyed to validate the reliability and validity of the scale.Results Exploratory factor analysis identified 1 factor that explained 69.532% of the variance. Confirmatory factor analysis showed that 1-factor structure with 13 items was not well fit, then 1 item with factor loading less than 0.6 was deleted and the new model fitted well.The Chinese version of the BCS was a single factor scale consisting of 12 items.The content validity index of the total scale was 0.985 and item-level content validity index ranged from 0.857 to 1.000.The Cronbach′s α coefficient for the scale was 0.956, the split-half reliability was 0.894 and the test-retest reliability was 0.895. Conclusion The Chinese version of the BCS is valid and reliable for mea-suring breathlessness catastrophizing in COPD patients in the Chinese context.
