Brief summary

The proposed investigation is an open label pilot study intended to establish the acceptability and feasibility of the Apollo in a population of Veterans. Exploratory data regarding biological signatures will also be collected.

Detailed description

Evaluation of Apollo requires a stepwise process in which initial aims are geared towards identifying biological signatures versus diagnosing, treating, mitigating or curing any conditions. Towards the end of identifying potential biological signatures, we hypothesize the following. 1) Participants who use the Apollo will have an attenuated physiological stress response as measured by improved heart rate variability (HRV) compared to baseline. 2) Participants who use Apollo will have attenuated perceived psychological stress measured by lower scores on psychological correlates of acute stress when compared to baseline

Interventions

DEVICEApollo Wearable System

Participants will be provided with the Apollo wearable device and asked to install the study mobile application on their mobile phone. Participants will use the Apollo for at least 30 minutes after waking up in the morning and at least 30 minutes before bed on the corresponding settings for those times of day. They will be given the Apollo Device TVS (10-200 Hz) to borrow which they will be instructed to wear for 6 +/- 2 weeks. They will be asked to continue to wear the device until all study data is collected.

Design outcomes

Primary

MeasureTime frameDescription
Feasibility via Client Satisfaction Questionnaire (CSQ)6 +/- 2 weeksClient Satisfaction Questionnaire (CSQ) is an eight-item questionnaire that will be used to assess patients' satisfaction with the intervention. The CSQ has good reliability and validity and has frequently been used to evaluate community mental health care.
Acceptability via Credibility Scale6 +/- 2 weeksThe Credibility Scale is a three-item questionnaire that will be used to assess patients' sense of the Apollo Wearable Device credibility.
Acceptability via Expectancy Scale6 +/- 2 weeksThe Credibility Scale is a two-item questionnaire that will be used to assess patients' expectations of the Apollo Wearable Device.
