BACKGROUND: Assessment of circulating and scrub skills is an important issue in operatingroom (OR) programs. However, there is a lack of well‑designed tools that are specifically developedfor this purpose. Hence, this study aimed to develop and determine the validity and reliability of achecklist to measure the circulating and scrub skills of OR novices.MATERIALS AND METHODS: This cross‑sectional methodological study was conducted among 124OR technology students who were selected during three consecutive academic years (2019–2020 to2021–2022). The developed checklist was evaluated with face validity, content validity (quantitativeand qualitative), construct validity (known‑groups validity), criterion‑related validity (concurrentand predictive validities), internal consistency (Kuder–Richardson 20, KR‑20), and inter‑raterreliability (intra‑class correlation coefficient, ICC). Known‑groups validity was evaluated by comparingthe difference between the checklist scores of first‑semester and third‑semester students usingindependent samples t‑test. Additionally, concurrent and predictive validities were evaluated by ICCthrough measuring the correlation between the total score of checklist and grades of a multiple‑choicetest and two clinical apprenticeship courses, respectively. Data were analyzed in the StatisticalPackage for Social Sciences software.RESULTS: After reconciling the preliminary checklist in terms of face and content validities, achecklist with 17 sub‑scales and 340 items called “Circulating and Scrub Skills of Operating RoomNovices (CSSORN)” was developed. Regarding the known‑groups validity, the third‑semesterstudents had higher scores compared to the first‑semester students (p < 0.001 in most sub‑scales).Besides, the total score of checklist showed a significant correlation with the criteria of concurrentand predictive validities (ICC = 0.64, ICC = 0.72; P < 0.001). The KR‑20 for the entire checklist was0.90 (range: 0.60–0.93). The ICC for inter‑rater reliability was also 0.96 for the entire checklist (range:0.76–0.99, P < 0.001 in all sub‑scales).CONCLUSION: The CSSORN had appropriate validity and reliability to be used for measuring thecirculating and scrub skills of OR novices. To shed light on the findings, further testing of this checkliston larger populations and in different contexts is suggested.
