To evaluate the validity and reliability evidence of the preceptor assessment of student tool (PAST) which was designed to assess doctor of pharmacy (PharmD) student rotation performance. Evaluation data were loaded into WINSTEPS software to conduct a Rasch rating scale analysis. Validity evidence was examined from construct and content validity perspectives, and reliability was assessed via student and item separation index and reliability coefficient. Data from 435 observations were included in the analysis. All 19 items measured the same construct of interest and the five-point rating scale functioned appropriately and differentiated students' ability. However, the item/person map indicated an absence of items at the end of the measurement continuum. Although adding items at the end of the measurement continuum may be beneficial, PAST showed good validity and reliability evidence when used to evaluate PharmD student rotations and is suitable to assess mastery learning.
为了评估预评估学生工具 (PAST) 的有效性和可靠性证据，该工具旨在评估药学博士 (PharmD) 学生的轮转表现。评估数据被加载到 WINSTEPS 软件中进行 Rasch 评分量表分析。从结构和内容有效性的角度检查有效性证据，并通过学生和项目分离指数和可靠性系数评估可靠性。分析中包括 435 次观察的数据。所有 19 个项目都测量了相同的感兴趣的结构，五分制评分量表功能正常，区分了学生的能力。然而，项目/人图表明在测量连续体的末端缺乏项目。尽管在测量连续体的末端添加项目可能是有益的，但当用于评估 PharmD 学生轮转时，PAST 显示出良好的有效性和可靠性证据，并且适合评估掌握学习。
