PURPOSE
The present study aimed to design a quantitative tool to evaluate the comfort and usability of working at height safety harnesses.
METHODS
This cross-sectional study was conducted in both qualitative and quantitative sections in 2022. The research steps included field interviews, an expert panel, and compiling the questionnaires for assessing the comfort and usability of the harness. The items of tools were designed based on the qualitative part of the research and review of the literature. The face and content validity of the instrument were assessed. Its reliability was also evaluated using the test-retest method.
RESULTS
Two tools were developed including a comfort questionnaire with 13 questions and a usability questionnaire with 10 questions. The Cronbach's alpha coefficients of these instruments were 0.83 and 0.79, respectively. Additionally, the content and face validity indices were 0.97 and 3.89 for the comfort questionnaire and 0.991 and 4 for the usability questionnaire, respectively.
CONCLUSIONS
The designed tools showed appropriate validity and reliability and could be used to evaluate the comfort and usability of safety harnesses. On the other hand, the criteria used in the designed tools could be employed in user-centered harness designs.
目的
本研究旨在设计一种定量工具，以评估高空作业安全带的舒适度和可用性。
方法
本横断面研究于2022年分定性和定量两部分进行。研究步骤包括现场访谈、专家小组以及编制评估安全带舒适度和可用性的问卷。工具的项目基于研究的定性部分和文献综述进行设计。评估了该工具的表面效度和内容效度。还采用重测法评估了其信度。
结果
开发了两种工具，包括一份有13个问题的舒适度问卷和一份有10个问题的可用性问卷。这些工具的克朗巴哈系数分别为0.83和0.79。此外，舒适度问卷的内容效度指数和表面效度指数分别为0.97和3.89，可用性问卷的分别为0.991和4。
结论
所设计的工具显示出适当的效度和信度，可用于评估安全带的舒适度和可用性。另一方面，所设计工具中使用的标准可用于以用户为中心的安全带设计。
