Cognitive and Mood Assessment Data in Major Depressive Disorder Using Digital Wearable Technology

The novel method being tested in this study for assessing mood and cognition in participants with MDD was wearable technology. This study looked at the correlation of mood and cognition outcomes on wearable technology with traditional objective neuropsychological cognitive function tests and self-reported mood outcomes. The study enrolled approximately 30 patients. Participants were provided with a watch on which brief cognitive and mood tests were evaluated daily up to 6 weeks. All participants prompted to complete cognitive and mood assessments on 3 occasions across the day. Two occasions (morning and afternoon) comprised assessment of cognition, and the final assessment in the evening constituted a review of the day focusing on self-reported depressed mood. This single-center trial was conducted in United Kingdom. The overall time to participate in this study was 6 weeks. Participants took part up to 5 study visits (1 in-person on-site visit, 3 web-based and 1 at home visit) assessing performance on traditional objective neuropsychological cognitive function tests and self-reported measures of depression symptom severity and social function.
