Methods： A methodological study design was used. The instrument was translated into Chinese and back-translated into English. A six-expert panel was invited to evaluate the content validity, and a pilot test was subsequently performed on the test-retest stability of the translated instrument. A convenience sampling method was used to recruit 240 nurses from a university teaching hospital in the Mainland of China. In total, 186 valid questionnaires were collected with a 77.5% valid return rate. The validity of the multiple-choice test items （item difficulties and discriminating indices） and internal consistency reli- ability were evaluated. Results： The translated and modified instrument demonstrated acceptable psychometric properties, as follows： （1） the overall content validity index （CVI） was 0.91, （2） the overall test-retest reliability was 0.826, （3） the item difficulty indices were between 0.46 and 0.93, （4） the overall values for discrimination were 0.28-0.55, and （5） the Cronbach＇s a for the internal consistency were 0.792 for the overall in- strument and 0.426-0.804 for the sub-themes. Conclusions： This study represents the first trial to translate and modify an existing instrument that measures the knowledge of pressure ulcers in a Chinese Mainland sample. The instrument demonstrated acceptable psychometric properties and could be applied in cross-cultural nursing practices, including nursing education, research and practice, to evaluate knowledge about pressure ulcer prevention.展开更多
