Casper, an online open-response situational judgement test that assesses social intelligence and professionalism [1], is used in admissions to health professions programs.
This study (1) explored the incremental validity of Casper over grade point average (GPA) for predicting student performance on objective structured clinical examinations (OSCEs) and fieldwork placements within an occupational therapy program, (2) examined optimal weighting of Casper in GPA in admissions decisions using non-linear optimization and regression tree analysis to find the weights associated with the highest average competency scores, and (3) investigated whether Casper could be used to impact the diversity of a cohort selected for admission to the program.
Multiple regression analysis results indicate that Casper improves the prediction of OSCE and fieldwork performance over and above GPA (change in Adj. R = 3.2%). Non-linear optimization and regression tree analysis indicate the optimal weights of GPA and Casper for predicting performance across fieldwork placements are 0.16 and 0.84, respectively. Furthermore, the findings suggest that students with a slightly lower GPA (e.g., 3.5-3.6) could be successful in the program as assessed by fieldwork, which is considered to be the strongest indicator of success as an entry-level clinician. In terms of diversity, no statistically significant differences were found between those actually admitted and those who would have been admitted using Casper.
These results constitute preliminary validity evidence supporting the integration of Casper into applicant selection in an occupational therapy graduate program.
Casper 是一种在线开放式反应情境判断测试,用于评估社会智能和专业精神[1],用于医疗专业课程的招生。
本研究(1)探讨了 Casper 在预测职业治疗课程中的客观结构临床考试(OSCE)和实地工作表现方面相对于平均绩点(GPA)的增量有效性,(2)使用非线性优化和回归树分析来检验 Casper 在 GPA 中的最佳加权在招生决策中,以找到与最高平均能力分数相关的权重,(3)研究了 Casper 是否可以用于影响入学计划的学生群体的多样性。
多元回归分析结果表明,Casper 提高了对 OSCE 和实地工作表现的预测能力,超过了 GPA(调整后的 R 值增加了 3.2%)。非线性优化和回归树分析表明,预测实地工作表现的 GPA 和 Casper 的最佳权重分别为 0.16 和 0.84。此外,研究结果表明,在实地工作中被评估为成功的学生,其 GPA 略低(例如 3.5-3.6),这被认为是作为入门级临床医生成功的最强指标。就多样性而言,实际录取的学生与使用 Casper 录取的学生之间没有统计学上的显著差异。
这些结果构成了初步的有效性证据,支持将 Casper 纳入职业治疗研究生课程的申请人选择。
