METHODS: Data were collected via the Internet in 24 countries, personal interviews in 7 countries, and both in 2 countries, using the Rome IV diagnostic questionnaire, Rome III irritable bowel syndrome questions, and 80 items to identify variables associated with FGIDs. Data collection methods differed for Internet and household groups, so data analyses were conducted and reported separately.
RESULTS: Among the 73,076 adult respondents (49.5% women), diagnostic criteria were met for at least 1 FGID by 40.3% persons who completed the Internet surveys (95% confidence interval [CI], 39.9-40.7) and 20.7% of persons who completed the household surveys (95% CI, 20.2-21.3). FGIDs were more prevalent among women than men, based on responses to the Internet survey (odds ratio, 1.7; 95% CI, 1.6-1.7) and household survey (odds ratio, 1.3; 95% CI, 1.3-1.4). FGIDs were associated with lower quality of life and more frequent doctor visits. Proportions of subjects with irritable bowel syndrome were lower when the Rome IV criteria were used, compared with the Rome III criteria, in the Internet survey (4.1% vs 10.1%) and household survey (1.5% vs 3.5%).
CONCLUSIONS: In a large-scale multinational study, we found that more than 40% of persons worldwide have FGIDs, which affect quality of life and health care use. Although the absolute prevalence was higher among Internet respondents, similar trends and relative distributions were found in people who completed Internet vs personal interviews.
OBJECTIVES: This study aims to compare student performance in MCQ and VSAQ and obtain feedback. from the stakeholders.
METHODS: Conduct multiple true-false, one best answer, and VSAQ tests in two batches of medical students, compare their scores and psychometric indices of the tests and seek opinion from students and academics regarding these assessment methods.
RESULTS: Multiple true-false and best answer test scores showed skewed results and low psychometric performance compared to better psychometrics and more balanced student performance in VSAQ tests. The stakeholders' opinions were significantly in favour of VSAQ.
CONCLUSION AND RECOMMENDATION: This study concludes that VSAQ is a viable alternative to multiple-choice question tests, and it is widely accepted by medical students and academics in the medical faculty.
