RESUMO
Background: studying the validity and reliability of short-form ]SF[-Nepean Dyspepsia Index ]NDI[ in patients with functional dyspepsia ]FD
Materials and Methods: after translating to Persian, the NDI-10 was filled out by 210 patients with FD, whose disease had been diagnosed by a gastroenterologist based on Rome 3 criteria, who admitted to Gastroenterology Clinic of Afzalipour Hospital in 2015. The reliability of the questionnaire was studied by test-retest and Cronbach's alpha coefficient. The validity of the questionnaire was evaluated through content-validity and criterion-validity
Results: through analyzing the results of test-retest of the questionnaire, the Pearson coefficient was obtained as 83%, which proves the reliability of the questionnaire. Criterion-validity with the correlation coefficient of 0.56 and content validity both proves the adequacy of questionnaire for measuring the quality of life in patients with FD
Conclusion: generally, Persian translation of this questionnaire has acceptable validity and reliability for measuring the quality of life in patients with FD
RESUMO
Background and Objectives: Even so much of the knowledge and skills of medical students is aquiered during clinical course, in many educational systems, students are kept away from clinical setting during their first academic years
Methods: This study was an interventional study carried out by Educational Development Office in the school of Medicine in 2009. All Second semester students were selected through census method. Students' attitudes towards medical profession were evaluated using a questionnaire, The validity of the questionnaire confirmed by a number of experts and its reliability was determined using Cronbach's Alpha 0.65. Early clinical exposure course was held for subjects and within two weeks after the course, they were asked to complete the questionnaire again. Each question vas rated using Likert scale and mean scores of each student before and after the intervention were calculated and compared by using paired t-test
Results: From 85 students, 62 ones completed the questionnaire before and after the course. From all 36 ones ]58 %] were female and 26 ones [42 %] were male. Mean age of students was I9.I2[+/- 0.73] years and their mean average of the first semester was I6.24[+/- 1.1]. There was no significant difference between the students' attitude toward medical profession before and after the course. Conclusion: Although the present study couldn't detect significant change in students' attitude toward medical profession, the results of other studies show that early clinical exposure provides an opportunity for the students to learn subjects practically and beyond mere theory
