ABSTRACT

The SmartPrompt is a smartphone-based reminder application informed by a neuropsychological model of functional disability. This laboratory-based pilot study examined the SmartPrompt feasibility, efficacy, and subjective usability using a within-participant, counterbalanced, cross-over design. Ten participants (M age = 80.3 + 8.2; M education = 15.7 + 2.5; 60% female) with mild cognitive impairment or mild dementia completed the Remember to Drink Test, which required preparing a glass of water at four predetermined times, in a SmartPrompt (SP) and Unprompted condition (UP). Written cues and a clock were available in both conditions; however, in the SP, the smartphone presented auditory alarms and visual reminders to obtain the water at specified times and required photo logging. In a separate session, caregivers were trained and tested on configuring the SmartPrompt. Overall, caregivers and participants learned to effectively use the SmartPrompt. Caregivers achieved near-perfect scores on the configuration quiz and responded well to training. Participants completed significantly more Remember to Drink tasks in the SP (93%) than UP (56%); checking the cues/clock decreased by 87% in the SP. Usability ratings were excellent among caregivers and fair among participants. Results indicate that the SmartPrompt holds promise for reducing functional disability in older adults with cognitive difficulties in at-home contexts.

摘要

SmartPrompt 是一款基于智能手机的提醒应用程序，由功能障碍的神经心理学模型提供信息。这项基于实验室的试点研究使用参与者内部、平衡、交叉设计检查了 SmartPrompt 的可行性、有效性和主观可用性。十名参与者（M年龄=80.3  +  8.2；M教育=15.7  + 2.5；60% 的女性）患有轻度认知障碍或轻度痴呆症完成了记得喝水测试，该测试需要在 SmartPrompt (SP) 和 Unprompted condition (UP) 的四个预定时间准备一杯水。在这两种情况下都可以使用书面提示和时钟；然而，在 SP 中，智能手机会发出声音警报和视觉提醒，以在指定时间取水并要求进行照片记录。在单独的会议中，护理人员接受了配置 SmartPrompt 的培训和测试。总体而言，护理人员和参与者学会了有效使用 SmartPrompt。护理人员在配置测验中取得了近乎完美的分数，并且对培训反应良好。参与者在 SP (93%) 中完成的 Remember to Drink 任务明显多于 UP (56%)；在 SP 中检查提示/时钟减少了 87%。可用性评级在护理人员中表现出色，在参与者中表现一般。结果表明，SmartPrompt 有望减少在家中有认知困难的老年人的功能障碍。
