Medical exam question difficulty prediction
Introduction Item difficulty prediction is crucial for planning and administrating educational assessments, especially those with high-stakes such as medical licensing examinations. The inconsistent findings across existing studies, however, highlight a critical gap in understanding which modeling components are most influential. This research addresses this gap by systematically investigating several key factors hypothesized to affect prediction…
Empowering Expert Judgment
A critical methodological challenge in standard setting arises in small-sample, high-dimensional contexts where the number of items substantially exceeds the number of examinees. Under such conditions, conventional data-driven methods that rely on parametric models (e.g., item response theory) often become unstable or fail due to unreliable parameter estimation. This study investigates two families of data-driven methods: information-theoretic an…
Common Persons Design in Score Equating
The Common Persons (CP) equating design offers critical advantages for high-security testing contexts—eliminating anchor item exposure risks while accommodating non-equivalent groups—yet few studies have systematically examined how CP characteristics influence equating accuracy, and the field still lacks clear implementation guidelines. Addressing this gap, this comprehensive Monte Carlo simulation ( N = 5,000 examinees per form; 500 replications…
Parent-adolescent discrepancies in perceived parental warmth and authoritarian parenting and early adolescents’ depressive symptoms
Comparison of missing data handling methods in cognitive diagnosis
摘要: 数据缺失在测验中经常发生, 认知诊断评估也不例外, 数据缺失会导致诊断结果的偏差。首先, 通过模拟研究在多种实验条件下比较了常用的缺失数据处理方法。结果表明:(1)缺失数据导致估计精确性下降, 随着人数与题目数量减少、缺失率增大、题目质量降低, 所有方法的PCCR均下降, Bias绝对值和RMSE均上升。(2)估计题目参数时, EM法表现最好, 其次是MI, FIML和ZR法表现不稳定。(3)估计被试知识状态时, EM和FIML表现最好, MI和ZR表现不稳定。其次, 在PISA2015实证数据中进一步探索了不同方法的表现。综合模拟和实证研究结果, 推荐选用EM或FIML法进行缺失数据处理
Association of Plasma DPP4 Activity and Brain-Derived Neurotrophic Factor With Moderate to Severe Depressive Symptoms in Patients With Type 2 Diabetes
OBJECTIVE: The objective of this study was to assess the association of plasma dipeptidyl peptidase-4 (DPP4) activity, brain-derived neurotrophic factor (BDNF), and the DPP4/BDNF ratio (DBR) with moderate to severe depressive symptoms in patients with type 2 diabetes mellitus. Increased DPP4 activity and decreased BDNF in peripheral circulation have been implicated in the pathophysiology of depression. METHODS: We performed a cross-sectional stud…
