3.3. Data Collection Tool and Technique
Two researcher-made questionnaires on students' attitudes and strength of motivation were used in this study. The questionnaires had been developed based on literature review. The students' attitudes questionnaire had 7 items graded based on a five-point Likert scale from strongly disagree = 1 to strongly agree = 5, and the strength of motivation tool had 16 items graded based on a five-point Likert scale from very low = 1 to very high = 5.
The face validity of questionnaires was determined with help from 20 medical students and 10 faculty members of medicine faculty. To this end, they were asked to express their opinions regarding the importance of each question in the questionnaires. For each question, three options of "important", "somewhat important", and "not important" were considered. In order to assess the content validity qualitatively, points assigned to items such as compliance with grammar and using appropriate words were examined by five faculty members. After the collection of panel group’s opinions, the necessary changes were made to the questionnaires. In addition, the content validity ratio (CVR) and content validity index (CVI) of the questionnaires were assessed regarding the necessity of an item inclusion based on the responses and three characteristics of clarity, ambiguity, appropriateness or relevance of items, respectively. Then, the questionnaires were sent to 10 faculty members of the nursing faculty. The reliability of the questionnaires was calculated adopting a split-half method and using Spearman correlation coefficient.
As for the intervention group (learning-in-hospital settings), a 4-day course with similar turns was designed in the form of four groups after making necessary arrangements with the hospital manager. Each group including 6 or 7 students was monitored and guided by a clinical supervisor. The program in each group consisted of two days attendance at hospital units with professor rounds, one day at teaching clinics, and one day at the emergency department.
The day before the project started, a briefing session was held and students became familiar with the title and objectives of the project to the extent that their pre-test response was not affected. They were also familiarized with their tasks during the course as well as with the different programs and activities in each group. In this session, students' questions about the length of the course, their tasks in each group, and different parts of the project were answered.
In this training course, no professional activities or special skills were presented to the students and only the execution of different educational levels and the work methods in the hospital were introduced and a situation was simulated so that the students experienced the real conditions of the clinical environment.
In the stage of familiarity with hospital ward, students were presented with the methods of bedside learning as well as with the approach professors adopt to deal with the students, patients, and different components of a teaching hospital. They were also allowed to observe the implementation of therapeutic and diagnostic procedures for the patients, learn about the role and duties of the professors, assistants, interns, and students in various stages, and deal with invasive diagnostic and treatment procedures.
In addition, students were allowed to observe and experience the difference between the clinical students and the patients and during their observations, therefore, they learned about the methods the interns adopted in order for inquiring about the patient's medical history and performing physical examinations.
By attending the hospital clinic, the students learned about the methods of patient treatment, the responsibilities each student, intern, assistant, and professor had in the teaching clinic, as well as the medical profession and doctor-patient difference in a more tangible way.
While in the emergency department, they were allowed to visit various emergency units and observe the condition of referred patients as well as the initial medical and diagnostic procedures.
At the end of the final day, the students were asked to answer the post-test questions in a session and discuss the methods for conducting the course as well as their impressions and opinions with the researchers.
As for the video-based education group, a short video was made after making necessary arrangements with the security unit and hospital manager as well as ensuring patients' privacy, which included the explanations of the clinical supervisor about the field of medicine, different courses for medical students, health care system in Iran, and all units of the hospital. After making arrangements with the Medical Education Development Center of the University, the film was played for students from the video-based education group in the central hall and, then, they were asked to answer the post-test questions. In this session, the clinical supervisor and the students discussed the methods of conducting the course and expressed their perceptions and opinions.
Ethical consideration: This research was carried out after obtaining the permission from the research council of Ilam University of Medical Sciences and the approval from the ethics committee (ethics code: ir.medilam.rec.1398.025), and after making arrangements with the hospital security and management unit.
