Zero-order and incremental validity coefficients, along with prediction models from all-subsets regression using Mallows Cp, are evaluated through cross-validation by splitting two medical school classes into screening and calibration samples. Evidence supports incremental validity for both tests, with larger coefficients for the New MCAT. Prediction models for NBME Part I and II are cross-validated, while clerkship performance models are equivocal.","ED 22941l  \nAUTHOR  \nTITLE  \nPUB DATE  \nNOTE  \nPUB TYPE  \n下  \nEDRS PRICE  \nDESCRI PTORS  \nI DENTIFIERS  \nABSTRACT  \nDOCUMENT RESUME  \nWolf,Fredric M.;And Others  \nComparison of the Incremental Valrdity of the Old andNew MCAT.  \nApr 83  \n39p.;Paper presented_at the Annual Meeting of theAmerican Educational Research Association(67th,Montreal,Quebec,April 11-15,1983).  \nSpeeches/Conference Papers(150)--Reports -Research/Technical(143)  \nMF-01/PC02 Plus Postage  \nAcademic Achievement;Admission Criteria;Biology;Chemistry;*College Entrance Examinations;,Comparative Analysis;*Competitive Selection;Correlation;Medical Education;*Medical Students;Predictive Measurement;*Predictive Validity;Regression(Statistics);*Test Validity  \n*Cross Validation;*Medical College Admission Test;National Board of Medical Examiners;Test Revision  \nThe predictive and incremental validity of both the01d and New Medical college Admission Test(MCAT)was examined andcompared with a sample of over 300 medical students.Results of zeroorder and incremental validity coefficients,as well as prediction  \nmodels resulting from all possible subsets regression analyses usingMallow's Cp criterion,were subjected to cross-validation analyses byrandomly dividing two medical school classes into screening andcalibration samples.Results supported the incremental validity ofboth the Old and New MCAT。Coefficients were generally larger for theNew than_for the Old MCAT.Prediction models of National Board ofMedical Examiners Part I and Part II performance,comprised of theNew Biology and Chemistry subtests and the 01d Science and GeneralInformation subtests were cross-validated.Prediction models ofclinical evaluation clerkship performance were equivocal.(Author)  \n****************★****★****★*★***★★**★**★**********★**★*★★*★*★★*★★★★*★★★  \n11462203  \nA(M)  \n7M83  \nU.3.DEPARTMENT OF EDUCATIONNATIONAL INSTITUTE OF EDUCATIONEOUCATIONAL RESOURCES INFORMATION  \nCENTER(ERIC)  \nX Ths document has boen roproducod arecorvad from tho person or organzationonginating !  \nMinor changos have been made to improvūroproductuon quality  \n● Points of yiew or opinions stoted in this document do not necessardy repres0nt officol NIEposition or policy  \n—  \n# Comparison of the Incremental Validityof the Old and New MCAT\n\nFredric M.Wolf,Judith G.Calhoun,Bruce R.Maxim,Wayne K.DavisUniversity of MichiganMedical School  \n\"PERMISSION TO·REPRODUCE THISMATERIAL HAS BEEN GRANTED BY  \nF m.心:16  \nTO THE EDUCATIONAL RESOURCESINFORMATION CENTER(ERIC).\"  \nAlan L.Hull  \nCase Western Reserve UniversitySchool of Medicine  \nRunning Head:Incremental Validity  \nPresented at the meeting of the American Educational Research Association,Montreal,April 1983.Correspondence may be addressed to the authors at theDepartment of Postgraduate Medicine and Health Professions Education,University of Michigan,G1208 Towsley Center,Ann Arbor,MI 48109.  \n# Comparison of the Incremental Validityof the Old and New MCAT\n\n虚  \nThe predictive and incremental validity of both the Old and New Medical CollegeAdmission Test(MCAT)was examined and compared with a sample of over 300 medicalstudents.
