目标膳食摄入量监测应用程序 (DIMA) 是一种电子膳食自我监测器,专为在个人数字助理 (PDA) 上使用而开发。本文描述了在 DIMA 的开发过程中如何考虑计算机、信息、数字和视觉素养。方法采用迭代、参与式设计方法。招募了 40 名在市中心设施接受血液透析的人,主要是中年人和非裔美国人。 结果通过评估完成传统/非传统 PDA 任务的能力来考虑计算机素养。通过使用通用产品代码 (UPC) 扫描仪、没有 UPC 代码的食品图片图标、录音机和具有文化敏感性的食品图标,信息素养得到了提高。通过设计 DIMA 来计算实时总计,数字素养得到提高,使个人能够看到相对于饮食处方的消耗量。通过设计图形界面来考虑视觉素养,以传达患者可以准确解释的 24 小时内的摄入数据。反馈图的图标使用患者能够理解的对象。实践意义初步数据表明,该应用程序对于个人自我监控摄入量非常有帮助。如果需要,DIMA 也可用于饮食咨询。
OBJECTIVEThe Dietary Intake Monitoring Application (DIMA) is an electronic dietary self-monitor developed for use on a personal digital assistant (PDA). This paper describes how computer, information, numerical, and visual literacy were considered in development of DIMA.METHODSAn iterative, participatory design approach was used. Forty individuals receiving hemodialysis at an urban inner-city facility, primarily middle-aged and African American, were recruited.RESULTSComputer literacy was considered by assessing abilities to complete traditional/nontraditional PDA tasks. Information literacy was enhanced by including a Universal-Product-Code (UPC) scanner, picture icons for food with no UPC code, voice recorder, and culturally sensitive food icons. Numerical literacy was enhanced by designing DIMA to compute real-time totals that allowed individuals to see their consumption relative to their dietary prescription. Visual literacy was considered by designing the graphical interface to convey intake data over a 24-h period that could be accurately interpreted by patients. Pictorial icons for feedback graphs used objects understood by patients.PRACTICE IMPLICATIONSPreliminary data indicate the application is extremely helpful for individuals as they self-monitor their intake. If desired, DIMA could also be used for dietary counseling.
