To develop and test a knowledge questionnaire about blood donation in African migrant communities in Australia, which is applicable to other communities, and to assess the relationship between the demographic and socio-economic characteristics and knowledge of the African migrant community.
Using a cross-sectional survey of 425 African migrants and refugees living in Victoria and South Australia, we assessed the knowledge questionnaire for readability, item difficulty, point-biserial correlation and reliability. The relationships between demographic and socio-economic factors and knowledge about blood donation were then evaluated using hierarchical multiple regression.
The knowledge scale was found to have good psychometric properties and to be reliable: a Flesch reading ease score of 64.7; an average index of item difficulty of 0.42; a point-biserial correlation of 0.38 and a Kuder-Richardson-20 coefficient of 0.78 indicating strong internal consistency. A quarter of respondents (26.1%; 95% CI: 21.9, 30.3) had poor knowledge about issues related to blood donation; 51.1% (95% CI: 46.3, 55.8) had moderate knowledge and 22.8% (95% CI: 18.8, 26.8) were highly knowledgeable. Factors associated with blood donation knowledge were religion, pre-migration area of residence, country of birth, length of stay in Australia, and previous blood donation status. Age, gender, educational attainment, migration and employment status were non-significant.
Knowledge and awareness of issues associated with blood donation is important in regard to blood donation decisions, and this article has developed a measure using African migrant communities in Australia that has appropriate psychographic properties. The measure can, therefore, be used by researchers when studying the role of knowledge in relation to blood donation across cultural groups in Australia and other countries. It also identifies that demographic characteristics affect knowledge, which suggests that targeted interventions might be needed, especially when dealing with migrant and refugee communities.
编制并测试一份关于澳大利亚非洲移民社区献血知识的问卷，该问卷适用于其他社区，并评估非洲移民社区的人口统计学和社会经济特征与知识之间的关系。
对居住在维多利亚州和南澳大利亚州的425名非洲移民和难民进行横断面调查，我们评估了知识问卷的可读性、项目难度、点二列相关和信度。然后使用分层多元回归评估人口统计学和社会经济因素与献血知识之间的关系。
发现该知识量表具有良好的心理测量特性且可靠：弗莱什易读性分数为64.7；项目难度平均指数为0.42；点二列相关为0.38，库德-理查森-20系数为0.78，表明内部一致性强。四分之一的受访者（26.1%；95%置信区间：21.9，30.3）对献血相关问题的了解较差；51.1%（95%置信区间：46.3，55.8）有中等程度的了解，22.8%（95%置信区间：18.8，26.8）知识丰富。与献血知识相关的因素有宗教信仰、移民前居住地区、出生国家、在澳大利亚的停留时间以及以前的献血状况。年龄、性别、教育程度、移民和就业状况无显著影响。
与献血相关问题的知识和意识对于献血决策很重要，本文利用澳大利亚的非洲移民社区编制了一种具有适当心理测量特性的测量方法。因此，研究人员在研究澳大利亚和其他国家不同文化群体中知识与献血的关系时可以使用该测量方法。它还表明人口统计学特征会影响知识，这表明可能需要有针对性的干预措施，尤其是在处理移民和难民社区时。
