目的 基于体验质量(Quality of Experience,QoE)理论构建智慧医院平台可用性量表,为智慧医院建设提供科学测量工具.方法 采用文献回顾、焦点会议法、预调查对量表条目进行筛选、修订,形成正式量表.便利选取山东省8所智慧医院平台的1 000名用户进行调查,评价量表的信度和效度.结果 智慧医院平台可用性量表包括6个维度24个条目.探索性因子提取出6个公因子:安全性、易用性、影响性、响应性、可靠性、灵活性.累计方差贡献率为64.045%,总体Cronbach's α系数为0.941,6个维度的Cronbach's α系数为0.782～0.963,重测信度为0.967.平均内容效度指数为0.972,条目水平内容效度指数为0.86～1.00.量表6个维度和系统可用性量表相关性系数为0.606～0.653,总体相关系数为0.647.结论 基于QoE理论的智慧医院平台可用性量表具有较好的信度和效度,可作为用户对智慧医院平台体验情况的测量工具.
Development of a Usability Scale for Smart Hospital Platforms Based on QoE Theory
Objective To construct a usability scale for smart hospital platforms based on Quality of Experience(QoE)theory,and provide scientific measurement tool for the construction,operation,and improvement of smart hospitals.Method Literature review,focus meeting method,and pre survey were used to screen and revise the scale items,forming a formal scale.Using convenience sampling method,1 000 users from 8 smart hospital platforms in Shandong Province were selected as the research subjects to evaluate the reliability and validity of the scale.Result The availability scale of the smart hospital platform includes 6 dimensions and 24 items.Exploratory factor extraction identified 6 common factors,with a cumulative variance contribution rate of 64.045%.The overall Cronbach's with a coefficient of 0.941 for 6 dimensions.The coefficient is between 0.782 and 0.963,and the retest reliability is 0.967.The Average Standardized Content Validity Index is 0.972,and the Item-level Content Validity Index is between 0.86 and 1.00.The correlation coefficient between the six dimensions of the scale and the System Usability Scale is 0.606-0.653,and the overall correlation coefficient is 0.647.Conclusion The usability scale of the smart hospital platform developed based on QoE theory has good reliability and validity,and can be used to measure the user experience of the smart hospital platform.
