The objectives of this study were to (1) identify factors predictive of performance on the National Board of Chiropractic Examiners Part IV exam and (2) investigate correlations between the scores obtained in the Part I, Part II, Physiotherapy, and Part III exams and the Part IV examination.
A random sample of 1341 records was drawn from National Board of Chiropractic Examiners data to investigate the relationships between the scores obtained on the National Board of Chiropractic Examiners exams. A hierarchical multiple regression analysis related the performance on Part IV to examinee's gender, Part IV repeater status, and scores obtained on the Part I, Part II, Physiotherapy, and Part III exams.
The analyses revealed statistical relations among all National Board of Chiropractic Examiners exams. The correlations between Part IV and Part I ranged from = .31 to = .4; between Part IV and Part II from = .34 to = .45. The correlation between Part IV and Physiotherapy was = .44; between Part IV and Part III was = .46. The strongest predictors of the Part IV score were found to be examinees' scores in Diagnostic Imaging, = .19, < .001; Chiropractic Practice, = .17, < .001; Physiotherapy, = .15, < .001; and the Part III exam = .19, < .001.
Performance on the National Board of Chiropractic Examiners Part IV examination is related to the performance in all other National Board of Chiropractic Examiners exams.
本研究的目的是（1）确定美国脊椎按摩疗法考试委员会第四部分考试成绩的预测因素，以及（2）调查第一部分、第二部分、物理治疗和第三部分考试成绩与第四部分考试成绩之间的相关性。
从美国脊椎按摩疗法考试委员会的数据中随机抽取1341份记录样本，以研究美国脊椎按摩疗法考试委员会各项考试成绩之间的关系。采用分层多元回归分析，将第四部分的成绩与考生的性别、第四部分重考状态以及第一部分、第二部分、物理治疗和第三部分考试的成绩联系起来。
分析揭示了美国脊椎按摩疗法考试委员会所有考试之间的统计关系。第四部分与第一部分的相关性在r = 0.31至r = 0.4之间；第四部分与第二部分的相关性在r = 0.34至r = 0.45之间。第四部分与物理治疗的相关性为r = 0.44；第四部分与第三部分的相关性为r = 0.46。发现第四部分成绩的最强预测因素是考生在诊断成像方面的成绩，r = 0.19，p < 0.001；脊椎按摩疗法实践，r = 0.17，p < 0.001；物理治疗，r = 0.15，p < 0.001；以及第三部分考试成绩，r = 0.19，p < 0.001。
美国脊椎按摩疗法考试委员会第四部分考试的成绩与美国脊椎按摩疗法考试委员会所有其他考试的成绩相关。
