Numerous studies have explored reliable variables that predict student success in dental hygiene programs and on the National Board Dental Hygiene Examination (NBDHE). However, no studies were found using data collected since the NBDHE format changed in 1998 to investigate if traditional predictors hold true. The objective of this study was to examine the relationship between pre-admission requirements, basic college science requirements, site of academic preparation, cumulative dental hygiene grade point average (CDHYGPA) and the NBDHE score.
Data from the academic records of 173 graduates of the dental hygiene program at The Ohio State University from 1998 through 2002 were entered into an Excel spreadsheet using identification numbers. Demographic information for the description of the subjects, course transfer data, course grades in program prerequisites and basic science requirements, CDHYGPA, and NBDHE scores were entered. Data were analyzed using the Statistical Package for the Social sciences (SPSS-version 10), Pearson's r correlations, regression analysis, and ANOVA with a predetermined level of significance at .05.
Of the 173 records entered, 132 had complete data (76.3%). Results indicate the existing prerequisites for the dental hygiene program remain strong predictors for success. A strong correlation was noted between human nutrition courses and the CDHYGPA. Other core science courses completed while in the program-anatomy, physiology and microbiology--also rendered a moderately strong correlation to the CDHYGPA. The greatest predictors for success on the NBDHE were the student's CDHYGPA and the prerequisite three science GPA. Consistency in site of science preparation also revealed a positive correlation to the CDHYGPA.
This study confirmed the continued use of the three science GPA pre-requisite and entering GPA for predicting success in this dental hygiene program and on the NBDHE even after the format changed to include case-based items. Other predictors for success that were identified in the study may aide dental hygiene program admission committees in their selection process. These committees may also consider the site of science preparation noting that institution consistency played a role in academic performance.
众多研究探讨了能够预测学生在口腔卫生项目以及国家口腔卫生委员会考试（NBDHE）中取得成功的可靠变量。然而，尚未发现有研究使用自1998年NBDHE考试形式改变后收集的数据来调查传统预测因素是否仍然适用。本研究的目的是检验入学前要求、大学基础科学要求、学术准备地点、口腔卫生累积平均绩点（CDHYGPA）与NBDHE考试成绩之间的关系。
使用识别号将俄亥俄州立大学1998年至2002年口腔卫生项目的173名毕业生的学术记录数据录入Excel电子表格。录入了用于描述受试者的人口统计学信息、课程转学分数据、项目先决条件和基础科学要求的课程成绩、CDHYGPA以及NBDHE考试成绩。使用社会科学统计软件包（SPSS - 10版）、皮尔逊积矩相关系数、回归分析以及显著性水平预先设定为0.05的方差分析对数据进行分析。
录入的173份记录中，132份有完整数据（76.3%）。结果表明，口腔卫生项目现有的先决条件仍然是成功的有力预测因素。人类营养课程与CDHYGPA之间存在强相关性。在项目期间完成的其他核心科学课程——解剖学、生理学和微生物学——与CDHYGPA也呈现出中等强度的相关性。NBDHE考试成功的最大预测因素是学生的CDHYGPA和先决条件的三门科学课程的平均绩点。科学准备地点的一致性也与CDHYGPA呈现正相关。
本研究证实，即使考试形式改变为包括基于案例的题目后，三门科学课程平均绩点先决条件和入学平均绩点仍可继续用于预测该口腔卫生项目以及NBDHE考试的成功情况。本研究中确定的其他成功预测因素可能有助于口腔卫生项目招生委员会的选拔过程。这些委员会还可考虑科学准备地点，注意到机构的一致性对学业成绩有影响。
