Background: Multiple choice questions (MCQs) or Items forms an important part to assess students in different educational streams. It is an objective mode of assessment which requires both the validity and reliability depending on the characteristics of its items i.e. difficulty index, discrimination index and distracter efficiency. To evaluate MCQs or items and build a bank of high-quality test items by assessing with difficulty index, discrimination index and distracter efficiency and also to revise/store or remove errant items based on obtained results.Methods: A preliminary examination of Third MBBS Part-1 was conducted by Department of Community Medicine undertaken for 100 students. Two separate papers with total 30 MCQs or items and 90 distractors each in both papers were analyzed and compared. Descriptive as well as inferential statistics were used to analyze the data.Results: The findings show that most of the items were falling in acceptable range of difficulty level however some items were rejected due to poor discrimination index. Overall paper I was found to be more difficult and more discriminatory, but its distractor efficiency was slightly low as compared to paper II.Conclusions: The analysis helped us in selection of quality MCQs having high discrimination and average difficulty with three functional distractors. This should be incorporated into future evaluations to improve the test score and properly discriminate among the students.

The Impact

Background: Multiple-choice questions (MCQs) are the most frequently accepted tool for the evaluation of comprehension, knowledge, and application among medical students. In single best response MCQs (items), a high order of cognition of students can be assessed. It is essential to develop valid and reliable MCQs, as flawed items will interfere with the unbiased assessment. The present paper gives an attempt to discuss the art of framing well-structured items taking kind help from the provided references. This article puts forth a practice for committed medical educators to uplift the skill of forming quality MCQs by enhanced Faculty Development programs (FDPs). Objectives: The objective of the study is also to test the quality of MCQs by item analysis. Methods: In this study, 100 MCQs of set I or set II were distributed to 200 MBBS students of Late Shri Lakhiram Agrawal Memorial Govt. Medical College Raigarh (CG) for item analysis for quality MCQs. Set I and Set II were MCQs which were formed by 60 medical faculty before and after FDP, respectively. All MCQs had a single stem with three wrong and one correct answers. The data were entered in Microsoft excel 2016 software to analyze. The difficulty index (Dif I), discrimination index (DI), and distractor efficiency (DE) were the item analysis parameters used to evaluate the impact on adhering to the guidelines for framing MCQs. Results: The mean calculated difficulty index, discrimination index, and distractor efficiency were 56.54%, 0.26, and 89.93%, respectively. Among 100 items, 14 items were of higher difficulty level (DIF I < 30%), 70 were of moderate category, and 16 items were of easy level (DIF I > 60%). A total of 10 items had very good DI (0.40), 32 had recommended values (0.30 - 0.39), and 25 were acceptable with changes (0.20 - 0.29). Of the 100 MCQs, there were 27 MCQs with DE of 66.66% and 11 MCQs with DE of 33.33%. Conclusions: In this study, higher cognitive-domain MCQs increased after training, recurrent-type MCQ decreased, and MCQ with item writing flaws reduced, therefore making our results much more statistically significant. We had nine MCQs that satisfied all the criteria of item analysis.

Background: Item analysis is the process of collecting, summarizing and using information from students’ response to assess the quality of test items. However it is said that MCQs emphasize recall of factual information rather than conceptual understanding and interpretation of concepts. There is more to writing good MCQs than writing good questions. The objectives of the study was to assess the item and test quality of multiple choice questions and to deal with the learning difficulties of students, identify the low achievers in the test. Methods: The hundred MBBS students from Government medical college were examined. A test comprising of thirty MCQs was administered. All items were analysed for Difficulty Index, Discrimination Index and Distractor Efficiency. Data entered in MS Excel 2007 and SPSS 21 analysed with statistical test of significance. Results: Majority 80% items difficulty index is within acceptable range. 63% items showed excellent discrimination Index. Distractor efficiency was overall satisfactory. Conclusions: Multiple choice questions with average difficulty and also having high discriminating power with good distracter efficiency should be incorporated into student’s examination.

Introduction: Multiple Choice Questions (MCQs) is one of the most preferred tool of assessment in medical education as a part of formative as well as summative assessment. MCQ performance as an assessment tool can be statistically analysed by Item analysis. Thus, aim of this study is to assess the quality of MCQs by item analysis and identify the valid test items to be included in the question bank for further use. Materials and methods: Formative assessment of Ist MBBS students was carried out with 40 MCQs as a part of internal examination in Biochemistry. Item analysis was done by calculating Difficulty index (P), Discrimination index (d) and number of Non- functional distractors. Results: Difficulty index (P) of 65% (26) items was well within acceptable range, 7.5% (3) items were too difficult whereas 27.5% (11) items were in the category of too easy. Discrimination Index (d) of 70% (28) items fell in recommended category whereas 10% (4) items were with acceptable, and 20% (8) were with poor Discrimination index. Out of 120 distractors 88.33% (106) were functional distractors and 11.66% (14) were non-functional distractors. After considering difficulty index, discrimination index and distractor effectiveness, 42.5% (17) items were found ideal to be included in the question bank. Conclusion: Item analysis remains an essential tool to be practiced regularly to improve the quality of the assessment methods as well as a tool for obtaining feedback for the instructors.

Background: Carefully constructed, high quality multiple choice questions can serve as effective tools to improve standard of teaching. This item analysis was performed to find the difficulty index, discrimination index and number of non functional distractors in single best response type questions.Methods: 40 single best response type questions with four options, each carrying one mark for the correct response, was taken for item analysis. There was no negative marking. The maximum marks was 40. Based on the scores, the evaluated answer scripts were arranged with the highest score on top and the least score at the bottom. Only the upper third and lower third were included. The response to each item was entered in Microsoft excel 2010. Difficulty index, Discrimination index and number of non functional distractors per item were calculated.Results: 40 multiple choice questions and 120 distractors were analysed in this study. 72.5% items were good with a difficulty index between 30%-70%. 25% items were difficult and 2.5% items were easy. 27.5% items showed excellent discrimination between high scoring and low scoring students. One item had a negative discrimination index (-0.1). There were 9 items with non functional distractors.Conclusions: This study emphasises the need for improving the quality of multiple choice questions. Hence repeated evaluation by item analysis and modification of non functional distractors may be performed to enhance standard of teaching in Pharmacology.

Abstract Background Distractor efficiency of multiple choice item responses is a component of item analysis used by the examiners to to evaluate the credibility and functionality of the distractors.Objective To evaluate the impact of functionality (efficiency) of the distractors on difficulty and discrimination indices.Methods A cross-sectional study in which standard item analysis of an 80-item test consisted of A type MCQs was performed. Correlation and significance of variance among Difficulty index (DIF), discrimination index (DI), and distractor Efficiency (DE) were measured.Results There is a significant moderate positive correlation between difficulty index and distractor efficiency, which means there is a tendency for high difficulty index go with high distractor efficiency (and vice versa). A weak positive correlation between distractor efficiency and discrimination index.Conclusions Non-functional distractor can reduce discrimination power of multiple choice questions. More training and effort for construction of plausible options of MCQ items is essential for the validity and reliability of the tests.
