بررسي ميزان روايي پيش بين آزمون هاي جامع علوم پايه دندانپزشكي در كفايت توانمندي باليني دانشجويان

Evaluation of the Predictive Validity of Comprehensive Basic Science Examination for the Adequacy of Dentistry Students' Clinical Competence

مقدمه: امتحان جامع علوم پايه، آزمون جامع دانشجويان دندانپزشكي است. انتظار مي رود روايي پيش بين لازم را براي غربال دانشجويان داشته باشد. هدف اين مطالعه تعيين ارتباط بين نمرات كسب شده در اين آزمون با توانمندي باليني دانشجويان بود كه مي تواند به عنوان نقش اصلي مورد انتظار نظام سلامت از دندانپزشكان باشد. مواد و روش ها:دانشجويان دندانپزشكي دانشكده دندانپزشكي مشهد در سه ورودي 1386 تا 1388 كه در امتحان جامع علوم پايه سال هاي 1388 تا 1390 شركت كرده بودند، انتخاب شدند. نمرات امتحان جامع علوم پايه دانشجويان و معدل نيم سال اول و دوم سال پنجم آنها، به عنوان سالي كه بيشترين واحد باليني را دارد، از پرونده آنان استخراج شد. ارتباط داده ها با استفاده از نرم افزار SPSS با ويرايش 11/5 مورد بررسي قرار گرفت. يافته ها: محاسبه ضريب همبستگي بين نمرات علوم پايه و معدل كل سال پنجم (p<0/001) و معدل نيم سال دوم (p<0/001) در هر سه دوره نشانگر همبستگي اين نمرات بود. محاسبه ضريب همبستگي بين نمرات علوم پايه و معدل نيم سال اول در دانشجويان ورودي 1388 و 1386 (p<0/001) و ورودي هاي 1387 (p=0/003) نيز نشانگر همبستگي اين نمرات بود. در كل دانشجويان پسر ارتباط معني داري بين نمرات علوم پايه و معدل كل سال پنجم (p=0/002) و معدل نيم سال اول (p<0/001) و معدل نيم سال دوم (p=0/005) وجود داشت. در كل دانشجويان دختر نيز ارتباط معني داري بين نمرات علوم پايه و معدل كل سال پنجم (p<0/001) و معدل نيم سال اول (p<0/001) و معدل نيم سال دوم (p<0/001) وجود داشت. نتيجه گيري: نتايج اين مطالعه نشان داد كه با وجود عدم تشابه سازه دروس علوم پايه و دروس باليني، آزمون علوم پايه مي تواند ابزار معتبري براي غربالگري دانشجويان در دوره هاي بعدي تحصيلي و شناسايي دانشجويان باشد.

Introduction: Basic Science Examination is the exam for dental students that should have sufficient predictive validity for screening students. The aim of this study was to determine the relationship between basic science examination scores and students, clinical competence as the main expected role for dentists in health system. Materials & Methods: Dentistry Students who had entered Mashhad Dental School in years 2007 to 2009 and participated in basic science examination in years 2009 to 2011 were selected. The students’ basic science examination scores and their average in first and second semester of the fifth year in dental school were extracted from their records. The relationship between the score and the average was investigated by SPSS version 11.5 software. Results: The calculation of correlation coefficients between the students’ basic science examination scores and their average in second semester of the fifth year and total average of fifth year in dental school (P<0.001) represented a significant correlation. Also the calculation of correlation coefficients between students’ basic science examination scores and their average in first semester of the fifth year in dental school for the Incoming students in 2001 & 2009 (P<0.001) and Incoming students in 2008 (P=0.003) represented a significant correlation. There was a significant correlation coefficient between each student’s basic science examination score and their average in first semester of fifth year (P<0.001) and second semester of the fifth year (P=0.005) and total average of fifth year (P=0.002) in dental school for all male students. Also there was a significant correlation coefficient between the student’s basic science examination score and their average in first semester of fifth year (P<0.001) and second semester of the fifth year (P<0.001) and total average of fifth year (P<0.001) in dental school for all female students. Conclusion: The results showed that despite the structural dissimilarity of basic sciences and clinical subjects, basic science examination can be a valid instrument for screening students for the next academic courses and identification of students
