The UK Clinical Aptitude Test (UKCAT) and its four subtests are currently used by 24 Medical and Dental Schools in the UK for admissions. This longitudinal study examines the predictive validity of UKCAT for final performance in the undergraduate medical degree programme at one Medical School and compares this with the predictive validity of the selection measures available pre-UKCAT.
This was a retrospective observational study of one cohort of students, admitted to Glasgow Medical School in 2007. We examined the associations which UKCAT scores, school science grades and pre-admissions interview scores had with performance indicators, particularly final composite scores that determine students' postgraduate training opportunities and overall ranking (Educational Performance Measure - EPM, and Honours and Commendation - H&C). Analyses were conducted both with and without adjustment for potential socio-demographic confounders (gender, age, ethnicity and area deprivation).
Despite its predictive value declining as students progress through the course, UKCAT was associated with the final composite scores. In mutually adjusted analyses (also adjusted for socio-demographic confounders), only UKCAT total showed independent relationships with both EPM (p = 0.005) and H&C (p = 0.004), school science achievements predicted EPM (p = 0.009), and pre-admissions interview score predicted neither. UKCAT showed less socio-demographic variation than did TSS.
UKCAT has a modest predictive power for overall course performance at the University of Glasgow Medical School over and above that of school science achievements or pre-admission interview score and we conclude that UKCAT is the most useful predictor of final ranking.
英国临床能力倾向测验（UKCAT）及其四个分测验目前被英国的 24 所医学和牙科学院用于招生。这项纵向研究考察了 UKCAT 对一所医学院本科医学学位课程最终成绩的预测效度，并将其与 UKCAT 之前可用的选择措施的预测效度进行了比较。
这是对一个队列学生的回顾性观察研究，这些学生于 2007 年被格拉斯哥医学院录取。我们考察了 UKCAT 分数、学校科学成绩和预录取面试分数与表现指标的关联，特别是决定学生研究生培训机会和总体排名的最终综合分数（教育表现衡量标准-EPM 和荣誉与表彰-H&C）。分析是在没有或调整潜在社会人口统计学混杂因素（性别、年龄、种族和地区贫困）的情况下进行的。
尽管 UKCAT 随着学生在课程中的进步而预测价值下降，但它与最终的综合分数相关。在相互调整的分析中（也调整了社会人口统计学混杂因素），只有 UKCAT 总分与 EPM（p=0.005）和 H&C（p=0.004）独立相关，学校科学成绩预测 EPM（p=0.009），而预录取面试成绩则没有预测到。UKCAT 比 TSS 具有更少的社会人口统计学差异。
UKCAT 对格拉斯哥大学医学院整体课程表现具有适度的预测能力，超过了学校科学成绩或预录取面试成绩，我们得出结论，UKCAT 是最终排名的最有用预测指标。
