Refining sleep measurement using the Motionwatch8©: how many days of monitoring do we need to get reliable estimates of sleep quality for older adults with mild cognitive impairment? Falck, Ryan S.; Barha, Cindy K.; Chan, Patrick C. Y.; Liu-Ambrose, Teresa

Abstract

Background: Poor sleep is common among older adults with mild cognitive impairment (MCI)—a transition stage between healthy cognition and dementia. Objective, reliable, and low-burden field methods to measure older adult sleep are also currently needed. The MotionWatch8© (MW8) wrist-worn actigraph provides estimates of sleep with 14 days of observation; however, there may be underlying differences in the reliability of sleep estimates based on MCI status. We therefore investigated the number of MW8 monitoring days required to estimate sleep in older adults with MCI and without. Methods: Older adults (55+ years; N = 151) wore the MW8 for ≥14 days. The Montreal Cognitive Assessment was used to categorize participants with probable MCI (scores of
