          Abstract

          Objective: The purpose of the study was to identify technical item flaws in the multiple choice questions submitted for the final exams for the years 2009, 2010 and 2011.

          Methods: This descriptive analytical study was carried out in Islamic International Medical College (IIMC). The Data was collected from the MCQ’s submitted by the faculty for the final exams for the year 2009, 2010 and 2011. The data was compiled and evaluated by a three member assessment committee. The data was analyzed for frequency and percentages the categorical data was analyzed by chi-square test.

          Results: Overall percentage of flawed item was 67% for the year 2009 of which 21% were for testwiseness and 40% were for irrelevant difficulty. In year 2010 the total item flaws were 36% and 11% testwiseness and 22% were for irrelevant difficulty. The year 2011 data showed decreased overall flaws of 21%. The flaws of testwisness were 7%, irrelevant difficulty were 11%.

          Conclusion: Technical item flaws are frequently encountered during MCQ construction, and the identification of flaws leads to improved quality of the single best MCQ’s.

            Multiple choice questions: a literature review on the optimal number of options.

            Single, best response, multiple choice questions (MCQs) with 4 options (3 distractors and 1 correct answer) or 5 options (4 distractors) have been widely used as an assessment tool in medical education in India and globally. Writing plausible distractors is time consuming and the most difficult part of preparing MCQs. If the number of options can be reduced to 3, it will make preparing MCQs less difficult and time consuming, thus reducing the likelihood of flaws in writing MCQs. We reviewed the literature to find out if the number of options in MCQ test items could be reduced to 3 without affecting the quality of the test. A systematic database search was done using the following question as a framework: How many options are optimal for multiple choice questions? Theoretical, analytical and empirical studies, which addressed this issue, were included in the review. There was no significant change in the psychometric properties of the 3 options test when compared with 4 and 5 options. MCQs with 3 options improved the efficiency of the test as well as its administration compared with 4- or 5-option MCQs. MCQs with 3 options had a higher efficiency because fewer distractors needed to be prepared, took up less space and required less reading time, decreased the time required to develop the items and the time to administer, and more items could be administered in a given time thus increasing the content sampled. Our review of the literature suggests that MCQs with 3 options provide a similar quality of test as that with 4- or 5-option MCQs. We suggest that MCQs with 3 options should be preferred.

              The frequency of item writing flaws in multiple-choice questions used in high stakes nursing assessments.

              Multiple-choice questions are a common assessment method in nursing examinations. Few nurse educators, however, have formal preparation in constructing multiple-choice questions. Consequently, questions used in baccalaureate nursing assessments often contain item-writing flaws, or violations to accepted item-writing guidelines. In one nursing department, 2770 MCQs were collected from tests and examinations administered over a five-year period from 2001 to 2005. Questions were evaluated for 19 frequently occurring item-writing flaws, for cognitive level, for question source, and for the distribution of correct answers. Results show that almost half (46.2%) of the questions contained violations of item-writing guidelines and over 90% were written at low cognitive levels. Only a small proportion of questions were teacher generated (14.1%), while 36.2% were taken from testbanks and almost half (49.4%) had no source identified. MCQs written at a lower cognitive level were significantly more likely to contain item-writing flaws. While there was no relationship between the source of the question and item-writing flaws, teacher-generated questions were more likely to be written at higher cognitive levels (p<0.001). Correct answers were evenly distributed across all four options and no bias was noted in the placement of correct options. Further training in item-writing is recommended for all faculty members who are responsible for developing tests. Pre-test review and quality assessment is also recommended to reduce the occurrence of item-writing flaws and to improve the quality of test questions.
