Test-retest reliability of multiple true-false questions in preclinical medical subjects

Abstract

It has been suggested that the 'ideal' measure of reliability of an examination is obtained by test and retest using the one examination on the same group of students. However, because of practical and theoretical arguments, most reported reliabilities for multiple choice examinations in medicine are actually measures of internal consistency. While attempting to minimize the effects of potential interfering factors, we have undertaken a study of true test-retest reliability of multiple true-false type multiple choice questions in preclinical medical subjects. From three end-of-term examinations, 363 items (106 of 449 from term 1, 150 of 499 from term 2, and 107 of 492 from term 3) were repeated in the final examination (out of 999 total items). Between test and retest, there was little overall decrease in the percentage of items answered correctly and a decrease of only 3.4 in the percentage score after correction for guessing. However, there was an inverse relation between test-retest interval and decrease in performance. Between test and retest, performance decreased significantly on 33 items and increased significantly on 11 items. Test-retest correlation coefficients were 0.70 to 0.78 for items from the separate terms and 0...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
