One common score reported from diagnostic classification assessments is the vector of posterior means of the skill mastery indicators. As with any assessment, it is important to derive and report estimates of the reliability of the reported scores. After reviewing a reliability measure suggested by Templin and Bradshaw, this article suggests three new measures of reliability of the posterior means of skill mastery indicators and methods for estimating the measures when the number of items on the assessment and the number of skills being assessed render exact calculation computationally burdensome. The utility of the new measures is demonstrated using simulated and real data examples. Two of the suggested measures are recommended for future use.

诊断分类模型中技能成就的后验概率的可靠性

诊断分类评估报告的一项共同得分是技能掌握指标的后均值向量。与任何评估一样，重要的是得出并报告所报告分数的可靠性的估计值。在回顾了Templin和Bradshaw提出的可靠性测度之后，本文提出了三种新的技能掌握度指标后验方法的可靠性测度，以及当评估项目的数量和所评​​估技能的数量准确时评估测度方法的方法。计算繁琐。使用模拟和真实数据示例演示了新措施的实用性。建议将其中两个建议措施用于将来使用。
