Abstract Background: The type of student admission may affect their educational performance. The purpose of this pilot was to compare the multiple-choice test statistics of medical and dental students' tests between free admission and tuition-paying admission under maximum matched conditions.Methods: This descriptive-analytical study was conducted at Golestan University of Medical Sciences in Iran in 2020. The study population included students of medicine and dentistry. A total of 56 tests were selected in two student groups of free admission and tuition-paying admission in basic sciences stages in the physiology course. The matched factors included test features consist of the number of questions, date of the test, test time, the volume of content, topics, and resources, and the instructors. The results of quantitative evaluation of tests were used as the data of this study. There were 21 items for each test including difficulty index, discrimination index, the degree of difficulty, score variance, and Kuder-Richardson correlation coefficient. Results: There were 16 medical and 14 dentistry tests with 437 and 330 questions respectively. The number of medical students participating in the free-tuition and paying-tuition admissions was 1336 and 1076, and for dental students, these numbers were 395 and 235 respectively. There were no significant differences in normalized adjusted test scores between two admission groups in both medical and dentistry tests. The discrimination index of tests was fair or good, and there were no cases of the negative or poor index. The mean of discrimination index in the free-tuition group was higher than in the paying-tuition group (p = 0.048). The interaction between the type of admission and the field was significant for the discrimination index (p = 0.0001). This difference was more in tuition-free dental students than tuition-free medical students and tuition-paying dental students. The mean difficulty index and the Kuder-Richardson correlation coefficient had no differences in the two groups. Conclusions: The type of student admission has no significant effect on students’ assessments in multiple choice tests in matched educational conditions.

Abstract Objective The aims of this study were to investigate the awareness, knowledge, and attitudes of Pakistani medical and dental undergraduate students toward COVID-19 during the surge of its outbreak. Materials and Methods The multicentered, cross-sectional study was carried out nationwide among undergraduate medical and dental students. A convenience sampling technique was used. A self-developed online questionnaire was pretested to be completed by the participants. It was distributed using social media. The survey was comprised of questions related to demographics, health status, general hygiene perception, understanding, and the learning attitudes of the students. Comparisons of the knowledge scores and the attitude responses with the demographic information were done using the independent t-test, one-way ANOVA, and Chi-square, as appropriate. Results Of the 937 total respondents, 353 (38%) were males and 582 (62%) were females; two students did not mark their gender. Of these, 680 (73%) were dental students and 257 (27%) were medical students. The mean knowledge score of the female dental students (5.15 ± 1.08) was significantly higher than that of the male students (4.87 ± 1.09). Overall, the mean knowledge score was statistically higher among the medical students in comparison to the dental students (5.21 ± 1.15, 5.05 ± 1.09; p = 0.054), respectively. Conclusion The medical and dental students were both aware of the importance of the use of a mask. The medical students had a greater awareness regarding the mode of transmission, symptoms, and origin of COVID-19. However, the dental students showed better understanding of the use of surgical masks and the correct protocol for hand washing. Social media was considered the main source for COVID-19 related information.

AbstractObjectivesThis study has been designed to elucidate the prevalence of stress, depression and poor sleep among medical students in a Pakistani medical school. There is a paucity of data on social support among medical students in Pakistan; an important predictor of depressive symptoms. Therefore, this study was also aimed to demonstrate the direct and indirect impact of social support in alleviating depressive symptoms in the study sample.MethodsThis observational cross-sectional study was conducted in Lahore, Pakistan, where a total of 400 students at a medical school were approached between 1st January to 31st March 2018 to participate in the study. The study sample comprised of medical and dental students enrolled at a privately financed Pakistani medical and dental school. The participants responded to a self-administered survey comprising of five parts: a) demographics, b) Pittsburgh Sleep Quality Index (PSQI), c) Patient Health Questionnaire-9 (PHQ-9), d) Multidimensional Scale of Perceived Social Support (MSPSS) and e) Perceived Stress Scale-4 (PSS-4). All data were analysed using SPSS v. 20. Linear regression analysis was used to reveal the predictors of depression.ResultsIn total, 353 medical students participated, yielding a response rate of 88.25%. Overall, poor sleep quality was experienced by 205 (58.1%) students. Mild to severe depression was reported by 83% of the respondents: mild depression by 104 (29.5%), moderate depression by 104 (29.5%), moderately severe depression by 54 (15.3%) and severe depression by 31 (8.8%) respondents. Subjective sleep quality, sleep latency, daytime dysfunction and stress levels were significantly associated with depression symptoms. Social support was not significantly associated with depressive symptoms in the regression model (Beta = -0.08, P < 0.09); however, it acted as a significant mediator, reducing the strength of the relationship between depressive symptoms and sleep quality and stress.ConclusionsAccording to our study, a large proportion of healthcare (medical and dental) students were found to be suffering from mild to moderate depression and experienced poor sleep quality. It is concluded that social support is an important variable in predicting depressive symptomatology by ameliorating the effects of poor sleep quality and high stress levels.

A study was undertaken to test the effect of open- vs. closed-book testing conditions on performance on a graduate-level, multiple-choice examination in pediatrics. A group of practicing pediatricians and a group of medical students took the examination. For the practice group, no significant difference between mean scores was observed, and the correlation between scores under the two testing conditions was high. In the student group, however, the mean score was significantly higher under open-book conditions and the correlation between scores under the two testing conditions was positive but low. The mean score obtained by practitioners was significantly higher than the mean score obtained by students under both testing conditions. The effects of time limit and level of motivation were not explored in the present study.

Objective. The purpose of this study was to examine the relationship between physical fitness, lifestyle, and academic performance of Chinese college students and investigate the differences among medical and dental students on their lifestyle. Methods. This study was conducted with 316 students enrolled from 2012 to 2014 at Tongji University. Scores from the college physical test were used to represent the students’ physical fitness condition. Lifestyle was measured by some variables extracted from the students’ behavior data provided by the university’s information center. Academic performance was measured by the average score of basic courses and the average score of professional courses. Demographic information, including age, gender, nation, and family background, was also obtained. Separate multiple linear regression analysis was performed for modeling academic performance and physical fitness with a p value threshold of 0.05. Results. A total of 212 (45.97% females) medical students and 104 (58.65% females) dental students participated in this study. Physical fitness score (medical: r = 0.34, p<0.001; dental: r = 0.47, p<0.001), library visiting frequency (medical: r = 0.30, p<0.001; dental: r = 0.62, p<0.001), number of books borrowed (medical: r = 0.19, p<0.01; dental: r = 0.37, p<0.001), frequency of waking up early (medical: r = 0.29, p<0.001; dental: r = −0.30, p<0.01), and times of eating breakfast (medical: r = 0.49, p<0.001; dental: r = 0.47, p<0.001) were all significantly associated with academic performance. Library visiting frequency (medical: r = 0.26, p<0.001; dental: r = 0.41, p<0.001) and eating frequency (medical: r = 0.48, p<0.001; dental: r = 0.42, p<0.001) were also closely related with physical fitness. Conclusion. Physical fitness, library usage, and the regularity of lifestyle are significant contributors to academic performance among Chinese medical and dental students. Moreover, medical students are shown to have less rest time compared to dental students.

Objectives: This study compared the empathic behaviour of first year to final year dental and medical students in Malaysia and explored whether academic training of dental and medical students increases their subjective empathic tendencies. Methods: This cross-sectional study was carried out among 1020 first year to final year (fifth-year) undergraduate medical and dental students using a validated, self-administered Jefferson Scale of Empathy-Health Care Provider Student Version (JSE-HPS) questionnaire. The data were collected from first year to final year (fifth-year) students enrolled in Bachelor of Medicine/Bachelor of Surgery (MBBS) and Bachelor of Dental Surgery (BDS) degree programs at 2 government-funded universities and one private university. Results: Dental students had a significantly higher total mean empathy score than medical students (84.11 versus 81.96, p < 0.05). However, medical students had a narrow actual score range (59.35 - 133.35) than dental (22.05 - 133.35) students. Males (Medical: 82.57, Dental: 84.97) and students of Malay origin (Medical: 82.52, Dental: 85.11) were more empathic than females and students of other ethnic origins. The results also indicate that third-year medical students (mean: 82.95) and fourth-year dental students (mean: 86.36) were more empathic than students in other professional years.Conclusions: We recommend the use of some form of active training and assessment to assist in the development of empathy in medical and dental students. Medical and dental schools should place more emphasis on teaching empathic communication.
