Development and validation of a questionnaire for feedback responses regarding the usefulness of the anatomical model to teach lung isolation skills

Background and Aims: An anatomical model was developed in-house to teach novices lung isolation skills bedside. To know the utility of the model, we planned a survey following a structured teaching program. The questionnaire used for feedback purpose was tested for content validity and has been detailed. Materials and Methods: Eleven questions were included in the survey. A Google form was prepared and mailed to 12 content experts to grade each question. In the Microsoft excel sheet, item-wise content validity index (I-CVI), scale-wise content validity index (S-CVI) and modified kappa statistic (κ) were calculated. The I-CVI of 0.78 and the S-CVI/average of 0.90 were considered acceptable. Results: Eleven out of 12 content experts responded. SCVI and S-CVI/Ave were uniformly 0.99 and 0.91, respectively, for relevance, simplicity, clarity, and ambiguity for all 11 questions. Conclusion: The questionnaire designed to obtain feedback regarding the anatomical model to teach lung isolation techniques met the content validity in both qualitative and quantitative terms.
