Clinical Evaluation Tool for Operating Room Students: Development and Measurement of Reliability and Validity

Introduction: In order to ensure the achievement of goals in clinical training, having the right tool with good reliability and validity is essential. Given the fact that no proper tool has ever been developed for evaluation of operating room students, this study aimed to develop and measure the validity and reliability of the evaluation tool for these students. Methods: This descriptive study was conducted in 2014 in Birjand University of Medical Sciences. After defining the concepts and behaviors to be measured using interviews and review of relevant literatures, the primary tool was developed and its face validity and content validity were verified both qualitatively and quantitatively (using experts’ opinions, CVR, and CVI). The reliability was calculated through interclass reliability and Cronbach’s alpha. Results: The final tool consisted of 62 items in 7 different subscales (professional characteristics, communication, examining the patient, training patients and families, submitting reports, clients’ safety, and clinical competence). The content validity index of the whole questionnaire was 0.84 and content validity ratio for each item was reported 0.62 and higher. With a sample size of 28 students, Cronbach's alpha of the whole questionnaire was 0.82. Also, interclass reliability was 0.45. Conclusion: The results indicated that the developed tool has adequate reliability and validity and that it can be used as a tool for clinical evaluation of operating room students.
