This study investigates the association between pre-National Board assessments and National Board Part 1 scores (NBCE) at a chiropractic college.
A convenience sample of 24 students enrolled in the doctor of chiropractic degree program was recruited for the study. These were 6th and 7th quarter students who had registered to take NBCE in March 2011. Each student's class scores were computed and average numeric means score derived. Subject clusters that make up testable subject categories in NBCE also were computed to obtain a single numeric mean score. Pretests were administered in all areas tested in NBCE. Results were compared to the student's scores in NBCE using correlation and multiple linear regression for 14 predictors and one response variable (NBCE).
Among the 14 correlations for 19 students (due to missing data when running the correlation matrix), six were moderate-to-strong and statistically significant. Two predictors qualified for multiple linear regression (where n = 22): mean anatomy and mean chemistry, both of which revealed similar regression coefficients.
Mean anatomy and mean chemistry scores were shown to be the best predictors of NBCE Part 1 results in this sample.
本研究调查一所脊椎按摩疗法学院的国家委员会预评估与国家委员会第1部分分数（NBCE）之间的关联。
招募了24名就读于脊椎按摩疗法博士学位课程的学生作为便利样本进行研究。这些是2011年3月注册参加NBCE考试的六年级和七年级学生。计算每个学生的课程成绩并得出平均数字平均分。还计算了构成NBCE中可测试学科类别的学科集群，以获得单个数字平均分。在NBCE测试的所有领域都进行了预测试。使用相关性和多元线性回归对14个预测变量和一个响应变量（NBCE）将结果与学生在NBCE中的分数进行比较。
在19名学生的14个相关性中（由于运行相关矩阵时存在缺失数据），6个具有中度到强度且具有统计学意义。两个预测变量符合多元线性回归条件（其中n = 22）：解剖学平均分和化学平均分，两者显示出相似的回归系数。
在这个样本中，解剖学平均分和化学平均分被证明是NBCE第1部分结果的最佳预测指标。
