The level of breastfeeding knowledge of nursing students may influence their ability to support breastfeeding families. However, to date, it has not been possible to measure this accurately due to the lack of existence of a validated tool in Chinese.
To translate the Comprehensive Breastfeeding Knowledge Scale (CBKS) into Chinese, and then evaluate its psychometric properties among Chinese undergraduate nursing students in order to inform and evaluate a nursing breastfeeding education programme.
The Brislin translation model was followed, and a three-phase process (translation, back-translation and cultural adaptation) was used to sinicize the CBKS and evaluate its content validity. Construct validity was evaluated with exploratory factor analysis (EFA), and the reliability of internal consistency of the Chinese version of the CBKS was tested by calculating Cronbach's alpha coefficient and the half reliability coefficient.
Two nursing schools in Beijing and Nanjing, China.
Four hundred and thirty-nine undergraduate nursing students (257 from Beijing and 182 from Nanjing).
Five experts rated the content validity of the Chinese version of the CBKS as excellent. EFA showed that the Chinese version of the CBKS had three subscales and 23 items. Cronbach's alpha coefficient of the Chinese version of the CBKS and the half reliability coefficient were 0.70 and 0.73, respectively. Students who had completed an obstetrics or paediatric nursing course had significantly higher total scores and mean scores for most items compared with those who had not taken a course. Most of the indictors of EFA met the standards of construct validity, and some were very close to the cut-off.
Overall, the 23-item Chinese version of the CBKS is an acceptable tool to measure the level of breastfeeding knowledge among undergraduate nursing students. This scale can be used to inform the design and evaluation of breastfeeding education materials for nursing students or other health profession students.
护理专业学生的母乳喂养知识水平可能会影响他们为母乳喂养家庭提供支持的能力。然而，由于缺乏经过验证的中文工具，迄今为止尚无法准确衡量这一水平。
将《综合母乳喂养知识量表》（CBKS）翻译成中文，然后在中国本科护理专业学生中评估其心理测量学特性，以便为护理母乳喂养教育计划提供信息并进行评估。
遵循Brislin翻译模型，采用三阶段过程（翻译、回译和文化调适）对CBKS进行汉化并评估其内容效度。通过探索性因子分析（EFA）评估结构效度，并通过计算Cronbach's α系数和半信度系数来检验中文版CBKS的内部一致性信度。
中国北京和南京的两所护理学院。
439名本科护理专业学生（257名来自北京，182名来自南京）。
5位专家将中文版CBKS的内容效度评为优秀。EFA表明中文版CBKS有三个分量表和23个条目。中文版CBKS的Cronbach's α系数和半信度系数分别为0.70和0.73。与未修过产科或儿科护理课程的学生相比，完成产科或儿科护理课程的学生在总分和大多数条目的平均分上显著更高。EFA的大多数指标符合结构效度标准，有些非常接近临界值。
总体而言，23条目的中文版CBKS是衡量本科护理专业学生母乳喂养知识水平的可接受工具。该量表可用于为护理专业学生或其他卫生专业学生的母乳喂养教育材料的设计和评估提供信息。
