Objective: This study investigates the association between pre-National Board assessments and National Board Part 1 scores (NBCE) at a chiropractic college.
Methods: 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).
Results: 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.
Conclusion: Mean anatomy and mean chemistry scores were shown to be the best predictors of NBCE Part 1 results in this sample.
