SECTION I. HOW DO YOU COMPARE TO YOUR PEERS?Welcome to the new Medical Knowledge Self-Assessment Program(MKSAP) Performance Interpretation Guidelines with Norm Tables. TheNORM TABLES were based on the results of pre-publication test-takerswho did not have access to the text, test answers, and critiques. The goal ofthis approach was to record test scores that realistically reflectedphysicians’ knowledge.This supplement will help you interpret your scores on the multiple-choicetests in the 16th edition of MKSAP and help you plan an individualizedprogram of continuing education. MKSAP 16 can also help you identifystrengths or weaknesses in specific subspecialty areas of internal medicine,enhance your general knowledge, keep you abreast of new developments,and prepare you for future examinations.MKSAP 16 was composed of three program components, referred to asParts A, B, and C. The first two components, Parts A and B, included Text,Bibliographies, and Multiple-Choice Questions for 11 internal medicinesubspecialty books. Part A was composed of six subspecialty test sections,and Part B was composed of five subspecialty test sections. Parts A and Balso included the Answers, Critiques, Educational Objectives, andBibliographies for Multiple-Choice Questions. Part C is this supplement,Performance Interpretation Guidelines with Norm Tables.You may also score your own tests by using the answer keys provided inSection V of this supplement and the Self-Scoring Instructions provided inSection VI.Page 6

To achieve the maximum educational benefit from Parts A and B ofMKSAP 16 you should rely on the materials listed below:1. Text and Multiple-Choice Questions2. Answers, Critiques, and Bibliographies3. Your Individual Score Reports, after submitting tests for CME credit4. This supplement, Performance Interpretation Guidelines with NormTablesPage 7

This supplement contains five additional sections.SECTION II.PARTICIPANT GROUPS.This section describesparticipants who submitted their tests for the analysis of data andnorm groups.SECTION III.SCORES.WHAT YOU NEED TO KNOW ABOUT YOURThis section describes the steps taken to ensure thevalidity of the test questions and the scores. It also describes howthe accuracy of the scores was evaluated and why this information isimportant.SECTION IV. NORM TABLES. This section contains norm data forparticipants and instructions for using the norm tables.SECTION V. ANSWER KEY AND PERCENTAGE ANSWERINGCORRECTLY.This section contains an answer key for eachsubspecialty section and defines the percentage of participantsanswering each test question correctly.SECTION VI. SELF-SCORING INSTRUCTIONS. This informationwill help you compute your percent correct score for eachsubspecialty section.Page 8

SECTION II. PARTICIPANT GROUPSBefore you interpret the statistics provided in Section III and use the NORMTABLES, consider which participants' scores were used to develop thedata. Groups were defined on the basis of information provided byparticipants in online question modules. These pre-publication participants,recruited through emails sent to ACP members and notices posted on theACP Web site, were asked to use their existing knowledge to answerquestions, without accessing clinical reference material. As part of a pretest screening process, physicians were asked to identify their primarysubspecialty and were excluded from accessing tests related to theirprimary area of expertise.SECTION III. WHAT YOU NEED TO KNOW ABOUT YOUR SCORESA. INTRODUCTIONParticipants in MKSAP 16 may note that their scores vary greatly from theNORM TABLES scores. There may be a variety of reasons for thisdiscrepancy. One, of course, is that some participants are significantly moreknowledgeable or less knowledgeable than other participants.Other factors that could contribute to score variance: Participants who read the text and soon thereafter answer the questionswill do better on the test than someone who answers the questionswithout having read the text. Those who read the test questions just before studying the text and thenanswer the questions may also score higher. Some participants take the test as a "closed book" exercise; others donot. Some participants seek consultation from content experts; others attendeducational group meetings before completing the tests. Your own scores may be influenced by such factors.Page 9

B. CONTENT VALIDITYThe validity of the scores relied on the expertise of distinguished cliniciansand educators who selected the content presented in each text section.Content in the text emphasized recent significant medical developments.Test questions reflected primarily the material presented in each textsection. After the questions were written, they passed through a series ofeditorial procedures designed to ascertain clarity, conciseness, andfreedom from technical flaws. Even after the tests were administered,questions with unusual statistical performance were reviewed again bycontent experts. Questions in these tests that were determined to beflawed, too ambiguous, outdated, erroneous, or too subspecialized havebeen excluded from scoring. These questions are not counted toward CMEcredit. The excluded questions include: Hematology and Oncology: question 114 Rheumatology: question 39 General Internal Medicine: question 7 Infectious Disease: question 97 Pulmonary and Critical Care Medicine: question 65Page 10

C. RELIABILITY (REL)It is important that test scores provide reliable estimates of ability. Thereliability (REL) coefficient was a measure of internal consistency thatprovided an estimate of the accuracy or stability of the scores. Anexamination was reliable to the extent that, if the ACP were to re-examineparticipants with a comparable form of the test, scores would be about thesame on the second test as on the first. The reliability coefficient may rangefrom 0.00 to 1.00.When scores are used to provide educational feedback for the assessmentof strengths and weaknesses, as they are for MKSAP 16, it isrecommended that the reliability be .70 or higher. The table below showsthe reliability for each subspecialty section.SUBSPECIALTY SECTIONRELCardiovascular Medicine.87Dermatology.80Gastroenterology and Hepatology.78Hematology and y and Metabolism.82General Internal Medicine.85Infectious Disease.83Nephrology.84Pulmonary and Critical Care Medicine.85Page 11

D. STANDARD ERROR OF MEASUREMENT (SEM)Ideally, the ACP would like to create tests that provide perfectly accuratemeasurements of participants' knowledge. In practice, however, scores arenever completely free of error; they are estimates of what might be called"true ability." The standard error of measurement (SEM) is an index thatindicates how much error there is in test scores.Using the SEM, it is possible to define a score interval that indicates how fara test score is likely to stray from a participant's true ability. The interval isfound by adding the SEM to a score and subtracting it from that score.Observed scores are expected to fall within one SEM of the true ability ofparticipants two times out of three, or approximately 67% of the time. Aparticipant whose true ability was 70 would usually receive a score between65 and 75 (70 - 5 and 70 5) in a test. The table below shows the SEM foreach subspecialty test.SUBSPECIALTY SECTIONSEMCardiovascular Medicine4.65Dermatology3.33Gastroenterology and Hepatology4.22Hematology and logy and Metabolism3.89General Internal Medicine5.29Infectious Disease4.58Nephrology4.55Pulmonary and Critical Care Medicine4.31Page 12

SECTION IV. NORM TABLESThe NORM TABLES are useful for determining your standing relative tothat of participants who completed tests before the program was published.Norm data are provided for each group of participants. The first columncontains PERCENT CORRECT SCORES. The remaining columns containPERCENTILE RANKS. The percentile rank indicates the percentage of thegroup that scores lower than the corresponding percent correct score.To use the NORM TABLES, first choose a percent correct score from eitheryour Individual Performance Report or your own hand score computations.Then select the table for the norm group with which you would like tocompare yourself. In the first column, locate your PERCENT CORRECTSCORE. Then read across the table to find your PERCENTILE RANK.For example, suppose that your score was 83% or 84% correct inCardiovascular Medicine. At the percent correct scores of 83-84 on theNORM TABLE, read across the page to the Cardiovascular Medicinecolumn to find your percentile rank of 97.3. Your percentile rank means that97.3 of the group scored lower than you in Cardiovascular Medicine.For each norm table, the N under the subspecialty section indicates theNumber of participants who completed tests for that subspecialty before theprogram was published.Page 13

SECTION VI. SELF-SCORING INSTRUCTIONSCompute your percent correct score as follows:Step 1. Give yourself a point for each correct response to each questionin the test in which you are working.Step 2. Divide the number of correct responses in Step 1 by the numberof “accepted” questions for the test in which you are working. Thenumber of “accepted” questions in each test is listed in the tableat the bottom of this page.Step 3. Multiply the result by 100.The final result will be your total percent score, which you may compare tothe Norm Tables under Section IV.ExampleInfectious DiseaseStep 1: Record your points.105Step 2: Divide the result by 107, which isthe total number of “accepted” questions.105 107Step 3: Multiply result by 100.981 x 100Total percent correct scoreSubspecialty SectionCardiovascular MedicineDermatologyGastroenterology and HepatologyHematology and OncologyNeurologyRheumatologyEndocrinology and MetabolismGeneral Internal MedicineInfectious DiseaseNephrologyPulmonary and Critical Care Medicine98%Number ge 36Number ofExcludedQuestions00010101101Number ofAcceptedQuestions1207296143969584167107108107
