目的：描述26个项目的远程医疗满意度和有用性问卷(TSUQ)的英语和西班牙语版本的编制和验证，报告糖尿病信息学教育和远程医疗(IDEATel)项目中城乡参与者的远程医疗满意度和有用性评分，并探索利用率与满意度和有用性之间的关系。方法：数据来源包括TSUQ、IDEATel日志文件中的利用数据和IDEATel年度访谈中的社会人口数据。采用心理测量学方法对TSUQ的信度和效度进行检验。结果：主成分因子分析提取了两个因子(视频访问量，α=.96，和。使用和影响，阿尔法=.92)，这解释了63.6%的TSUQ满意度得分的差异。所有的满意度和有用性项目在5分制中的平均得分都大于4。来自城市地区的参与者在这两个因素上的评分都明显高于农村参与者，而那些在基线水平上不知道如何使用计算机的参与者也是如此。IDEATel成分的平均使用频率在血糖检测中最高，其次是回顾结果的网站、血压测试、视频访问和ADA教育网页。结论：心理测量学分析支持TSUQ的结构效度和内部一致性信度，该量表有英文和西班牙文两种版本，可读性为8年级。农村和城市参与者都报告了很高的满意度，并发现IDEATel的所有组成部分都很有用。还需要进一步开展工作，以审查利用情况与满意度和有用性之间的关系，并探讨地点(城市与农村)和族裔对远程医疗服务满意度的影响。
Objectives: To describe the development and validation of low literacy English and Spanish versions of the 26-item Telemedicine Satisfaction and Usefulness Questionnaire (TSUQ), report telemedicine satisfaction and usefulness ratings of urban and rural participants in the Informatics for Diabetes Education and Telemedicine (IDEATel) project, and explore relationships between utilization and perceptions of satisfaction and usefulness.Methods: Data sources included TSUQ, utilization data from IDEATel log files, and sociodemographic data from the annual IDEATel interview. Psychometric analyses were conducted to examine the reliability and validity of TSUQ. Data were analyzed using descriptive, correlational techniques.Results: The principal components factor analysis extracted two factors (Video Visits, alpha = .96, and. Use and Impact, alpha = .92) that explained 63.6% of the variance in TSUQ satisfaction scores. All satisfaction and usefulness items had mean scores of greater than 4 on a 5-point scale. Those from urban areas reported significantly higher ratings on both factors than rural participants as did those who did not know how to use a computer at baseline. Mean frequency of utilization of IDEATel components was highest for blood sugar testing followed by web site for reviewing results, blood pressure testing, video visits, and ADA educational Web pages. Associations between utilization and perceptions of satisfaction and usefulness varied among IDEATel components.Conclusion: Psychometric analyses support the construct validity and internal consistency reliability of TSUQ, which is available in both English and Spanish at a readability level of 8th grade. Both rural and urban participants reported high levels of satisfaction and found all IDEATel components useful. Further work is needed to examine the relationships between utilization and perceptions of satisfaction and usefulness and to explore the effects of location (urban versus rural) and ethnicity on satisfaction with telemedicine services.
