Zimet's knowledge of AIDS scale was completed anonymously by 2,209 university students to assess whether a split-half approach in which items in each half were matched for content would provide better estimates of reliability than other method. Analysis indicates that the odd even Spearman Brown split-half reliability coefficient was lower than both the alpha coefficient and the content-based split-half coefficient. The Cronbach alpha was similar to the content-based Spearman-Brown reliability coefficient.
齐梅特艾滋病知识量表由2209名大学生匿名完成，以评估一种将每半部分的项目按内容进行匹配的分半方法是否能比其他方法提供更好的信度估计。分析表明，奇偶斯皮尔曼 - 布朗分半信度系数低于阿尔法系数和基于内容的分半系数。克朗巴赫阿尔法系数与基于内容的斯皮尔曼 - 布朗信度系数相似。
