Data sources and measurement
To measure the level of satisfaction of the students, a researcher-made satisfaction questionnaire was used. The first section of this questionnaire dealt with demographic information (age, sex, academic year, and overall grade point average). The second section consisted of 20 items scored based on a 5-point Likert scale (from completely disagree [1 point] to completely agree [5 point]), with a minimum score of 20 and a maximum score of 100. The items examined in this questionnaire included the guide for using the logbook, appearance characteristics, ease of use, speed of evaluation and provision of feedback, impact on motivation, impact on self-confidence, educational communication between the student and the clinical instructor, and speed of correction and improvement of clinical performance. Based on this questionnaire, a score between 20 and 39 represented complete dissatisfaction, 40 to 59 relative dissatisfaction, 60 to 79 relative satisfaction, and 80 to 100 complete satisfaction. After the questionnaire was developed based on textbooks, articles, and other reliable sources, its content validity was confirmed by the faculty members of the AJUMS Department of Anesthesiology and Medical Education using a qualitative approach. Then, the questionnaire was piloted to 30 nursing anesthesia students who were not among the final participants. Their comments were applied to confirm the face validity of the tool. Next, the reliability of the questionnaire was confirmed by an obtained Cronbach α coefficient of 0.96 (The third section of the tool was an anesthesia skills evaluation checklist used in the logbooks, developed and approved by faculty members based on valid anesthesia sources and a literature review (
