ABSTRACT

Background:

Wearable physiological monitoring devices enable the continuous measurement of human behavior and psychophysiology in the real world. Although such devices are promising, their availability does not guarantee that participants will continuously wear and interact with them, especially during times of psychological distress. Wearable physiological monitoring devices enable the continuous measurement of human behavior and psychophysiology in the real world. Although such devices are promising, their availability does not guarantee that participants will continuously wear and interact with them, especially during times of psychological distress.

Objective:

The goal of this study was to evaluate the feasibility and acceptability of using a wearable behavioral and physiological monitor, the Empatica E4, to continuously assess a group of suicidal adolescent inpatients.

Methods:

Participants (n = 50 adolescent inpatients) were asked to wear an Empatica E4 on their wrist for the duration of their inpatient stay. In addition to assessing behavioral meta-data (e.g., hours worn per day) we also used qualitative interviews and self-report measures to assess participants’ experience of wearing the device.

Results:

Results supported the feasibility and acceptability of this approach. Participants wore the device for average for 18 hours a day and reported that despite sometimes finding the device uncomfortable, they did not mind wearing it. Many of the participants noted that the part of the study they enjoyed most was contributing to scientific understanding, especially if it could help people like them in the future.

Conclusions:

These findings provide promising support for using wearable monitors in clinical samples in future studies, especially if participants are invested in being part of a research study.
