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

2 juillet 2018 mis à jour par: Takeda

A Single Center Pilot Study to Evaluate Real Time Passive and Active High-Frequency Cognitive and Mood Assessment Data in Major Depressive Disorder Using Digital Wearable Technology

The purpose of this study was to evaluate the feasibility and compliance with a novel method for assessing mood and cognition in participants with major depressive disorder (MDD).

Description détaillée

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.

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Percentage of Days on Which Daily N-back Sessions Were Completed
Délai: Baseline up to Week 6
The cognitive assessment n-back test was completed on the wearable technology (Apple watch) on 3 occasions across the day in the morning, afternoon and evening.
Baseline up to Week 6
Percentage of Days on Which Daily Mood Assessment Tests Were Completed
Délai: Baseline up to Week 6
The Daily Mood assessments were completed on the wearable technology (Apple watch) once per day in the afternoon or evening.
Baseline up to Week 6
Correlation Coefficient Between Measures of Cognition (N-back Scores) and Performance on the Cambridge Neuropsychological Test Automated Battery (CANTAB) Tests: Spatial Working Memory Between Errors (SWMBE) and Spatial Working Memory Strategy (SWMS)
Délai: Baseline up to Week 6

The n-back was used to assess cognition 3 times a day. Participants responded by touching the watch face when a symbol matched the one presented 2-back. Average daily n-back score (d-prime) was calculated.

CANTAB tests consists of a battery of neuropsychological tests. Spatial Working Memory (SWM) assessed retention of spatial data, ability to manipulate remembered items and strategize. Participant was asked to find tokens in on-screen boxes and move them.

SWMBE=cumulative number of times participant went back to box that a token was previously removed per each successful study. Lower score was better.

SWMS=number of unique boxes participant searched in two 6 and 8 box trials. Total of 4 trial scores ranged from 4-28. Lower score indicated better performance.

Pearson's correlation coefficient measured linear correlation between n-back scores from Apple Watch and CANTAB tests, provided as a value +1=positive correlation to -1=negative correlation. 0=no correlation.
Baseline up to Week 6
Correlation Coefficient Between Measures of Cognition (N-back Scores) and Performance on the CANTAB Test: Rapid Visual Information Processing (RVP)
Délai: Baseline up to Week 6

The n-back was used to assess cognition 3 times a day. Participants responded by touching the watch face when a symbol matched the one presented 2-back. Average daily n-back score (d-prime) was calculated.

CANTAB tests consists of a battery of neuropsychological tests. RVP measures sustained attention. A white box appears in the center of the computer screen, inside which digits, from 2 to 9, appear in a pseudo-random order, at the rate of 100 digits per minute. Participants are requested to detect target sequences of digits.

RVPA=measure of sensitivity to the target, regardless of response tendency (expected range is 0.00 to 1.00).

Speed of Processing (RVPMDL)=The mean response latency during assessment sequence blocks where the participant responded correctly.

Pearson's correlation coefficient measured linear correlation between n-back scores from Apple Watch and CANTAB tests, provided a value +1=positive correlation to -1=negative correlation. 0=no correlation.
Baseline up to Week 6
