简要总结
The purpose of this study is to develop and test a physical activity-tracking smartphone app designed to facilitate physical activity in older adults with mild cognitive impairments or mild dementia. The app targets provides tips, messages, and strategies to overcome common barriers older adults face to being physically active. Participants will include older adults with memory or thinking problems or those diagnosed with mild cognitive impairment or mild forms of dementia who are smartphone users age 65 years or older and who are not meeting nationally recommended levels of physical activity. In the clinical trial phase of this study, 15 participant-study partner dyads will be oriented to the app and use it for a two-month period. Dyads will keep a diary to document their experiences and participants' activity patterns will also be tracked at the beginning and end of the study. After the two-month app trial is complete, dyads will return for a follow-up interview to discuss their experiences and provide suggestions for app improvements. Findings from this stage of the overall study will be combined with previous study phases to derive specifications for an optimized app for older people with mild cognitive impairments or mild dementia.

入选标准
- •Target User:
- •65+ years old
- •English speaking;
- •resides in local Los Angeles area or the Pacific Time Zone;
- •self-reported memory or thinking problems that score within a range of mildly impaired on a cognitive test or a clinical diagnosis of cognitive impairment ranging from mild cognitive impairment (MCI) or mild dementia (of any form). Mild dementia is the top end of this clinical diagnosis range. MCI is the low end of the range.
- •reports <150 minutes of moderate to vigorous physical activity per week as per a single-item screener;
- •self-reported ability to safely engage in regular walking;
- •smartphone owner of a compatible smartphone for ≥1 month;
- •willing and available second family member/friend/caregiver who owns a smartphone and can attend training sessions; and
- •observed ability to reliably access and operate a smartphone during training.
排除标准

- •recent cognitive status does not fall within an acceptable MCI/mild dementia range as determined through Montreal Cognitive Assessment (MoCA) if diagnosis was unverified by health care provider or by ADRC or memory and thinking problems were self-reported
- •recent cognitive status is below what is acceptable for MCI/mild dementia as determined through MoCA if diagnosis was verified by health care provider or ADRC
- •Inclusion Criteria - Study Partner:
- •English-speaking

研究组 & 干预措施
Target Users - Moving Up-A app
In this single-arm trial, target users (participants) will use a physical activity smartphone app for a two-month period. The app includes motivational messages, tips to increase the intensity level of everyday activities, and strategies to reduce sedentary behaviors. Users can also track their physical activity levels and sedentary activity.
干预措施: Moving Up - A (Behavioral)
Study Partners - Moving Up-A app
In this single-arm trial, study partners were invited to support target users (participants) in using a physical activity smartphone app for a two-month period. The app includes motivational messages, tips to increase the intensity level of everyday activities, and strategies to reduce sedentary behaviors. Users can also track their physical activity levels and sedentary activity.
干预措施: Moving Up - A (Behavioral)
结局指标
主要结局
Daily Steps Change From Baseline to Month 2
时间窗: baseline and 2 months
Step counts (objective physical activity) were measured using the activPAL thigh-worn accelerometer during a 96-hour monitoring period. Change is computed as the activPAL-tracked mean daily steps at Month 2 minus that value at baseline
次要结局
- App Usability Measured Using the User Version of the Mobile Application Rating Scale (uMARS)(Month 2)
- Daily Sitting Time (activPAL) Change From Baseline to Month 2(baseline and 2 months)
- App Usage Behavior(from baseline through Month 2 (daily))
