Abstract

Multiple Choice Questions (MCQs) are widely used as cognitive assessment tools in medical education due to their efficiency and objectivity. The quality of MCQs is strongly influenced by the alignment between examination planning through blueprinting and the empirical performance of test items evaluated using item analysis. This study aimed to examine the alignment between the examination blueprint and item analysis results as indicators of MCQ instrument validity. This study employed a descriptive observational quantitative design with a retrospective approach. Data were obtained from examination blueprint documents and MCQ test results from the most recent block examination conducted at the Medical Study Program, Faculty of Medicine, Universitas Muhammadiyah Palembang. A total of 150 MCQ items were analyzed using statistical software to calculate difficulty index, discrimination index, and internal reliability measured by Cronbach’s alpha coefficient. The results demonstrated that most items were classified within the moderate difficulty category (47.33%), with relatively balanced proportions of difficult and easy items. Item discrimination analysis revealed that 70.67% of items showed good discrimination (?0.30), although 29.33% of items demonstrated fair to poor discrimination. The internal reliability of the examination instrument was very high, with a Cronbach’s alpha value of 0.91. In conclusion, the alignment between the examination blueprint and item analysis findings supports the validity and reliability of the MCQ assessment instrument. Nevertheless, continuous evaluation and revision of items, particularly those with low discrimination indices, are recommended to enhance the overall quality of assessment.

Abstract

ABSTRACTEye strain (asthenopia) is a common complaint resulting from the increasing use of digital devices. Data from the World Health Organization (WHO) indicate that the global prevalence of asthenopia ranges from 75% to 90%. The growing use of smartphones, particularly among university students, has the potential to increase the risk of this condition. This study aims to analyze the relationship between smartphone usage characteristics—namely viewing distance, duration of use, and usage position—and the occurrence of eye strain among students. This research employed an analytical observational design with a cross-sectional approach. The sample consisted of 209 students selected through proportionate stratified random sampling. Data were collected using a smartphone usage questionnaire and the Visual Fatigue Index (VFI), and subsequently analyzed using the chi-square test with a 95% confidence level. The results showed that 78% of respondents experienced eye strain. There was a significant relationship between viewing distance (p=0.001), duration of use (p=0.001), and smartphone usage position (p=0.001) and the incidence of eye strain. In conclusion, ergonomic factors related to smartphone use play an important role in the development of eye strain. Education on proper device usage is necessary to minimize the risk of eye health problems.Keywords: distance, duration, smartphone, eye strain
