Objective To translate the Context Assessment for Community Health(COACH)scale into Chinese,thereby providing a standardized measurement tool for context assessment in clinical evidence-based practice.Methods The scale was translated following the Brislin translation model,ultimately forming the Chinese version of the COACH scale.Using convenience sampling,584 healthcare professionals were recruited from 3 tertiary hospitals in Jiangxi,Henan,and Liaoning provinces and 2 community hospitals in Liaoning province from May to September 2024 to evaluate the reliability and validity of the scale.In October 2024,the Chinese version of COACH was applied to 44 healthcare professionals in a hypertension specialist ward of a provincial tertiary hospital.Results Of the 584 distributed questionnaires,519 valid questionnaires were collected(the effective response rate of 88.87％).The Chinese version consists of 7 dimensions with 42 items.The overall Cronbach's α coefficient was 0.975;the McDonald's omega coefficient was 0.979;split-half reliability was 0.808,and the test-retest reliability was 0.917.The scale-content validity index/average was 0.950,and the scale-content validity index/universal agreement was 0.980,with item-content validity index ranging from 0.775 to 1.000.Exploratory factor analysis extracted 7 factors,accounting for 79.260％of the cumulative variance,with factor loadings ranging from 0.569 to 0.954.Confirmatory factor analysis showed good model fit.The preliminary application results showed that the total score of the scale was 185.18±17.82.The correlation coefficients between dimensions and total score ranged from 0.116 to 0.905.Conclusion The Chinese version of the COACH scale demonstrates good reliability and validity,making it suitable as a context measurement tool for implementation research at different stages in clinical and public health settings.
