Abstract

Introduction: Usability is an index to assess a product from the viewpoint of user's satisfaction, efficiency and productivity improvement. The main attributes of Usability that are derived from the human factors and are used in Usability design of the interfaces include: compatibility, consistency, flexibility, minimal action, perceptual limitation, usefulness, learnability, ease of use, minimal memory load, user guidance, satisfaction and errors. The main aim of this study was to assess the Usability of interface design tool for a Ventilator utilized in the hospitals of Arak city, Iran, and to study its validation and Reliability. Methods: After constructing the initial questionnaire from the standard sources, specific techniques to determine the validity, and Cronbach's alpha coefficient were used for the validity and Reliability study. The study procedure was determining the scope and dimensions of the questions, drafting questionnaire, assigning members of the expert panel, study, questionnaire data acquisition and analysis methods, determining acceptance criteria of the questions and the Content validity and Reliability index. Final tool was a 42-items questionnaire. Results: The Content validity index (CVI) of questionnaire was 0. 86. The results showed that the total Cronbach's alpha coefficient was 0. 89 as an acceptable value for the Reliability of questionnaire. Conclusion: After designing the final questionnaire, and the reaching to the appropriate validity and Reliability, adopting this tool to assess the Usability of breathing apparatus (Ventilator) is recommended. With Usability assessment of such vital instruments, quality improvement, higher efficiency and productivity as well as errors reduction and good design user interface will be achieved.
