Study Summary
This study is designed as an open label, single arm, decentralized clinical study in which first responders will receive transcutaneous auricular neurostimulation (tAN), which targets the auricular branch of the vagus nerve (ABVN) via the mastoid and the auriculotemporal nerve (ATN) anterior to the tragus. Participants will be enrolled in the study over the course of eight weeks (56 days). Participants will respond to daily and weekly questionnaires regarding mood, stress, sleep, energy/fatigue, and burnout. Each week, participants will complete consolidated online questionnaires (intended to last no longer than 15 minutes) comprised of the Perceived Stress Short-Form (PSS-4), Well-Being Index (WHO-5), Mini-Z Burnout (5-item), PROMS Sleep Disturbance (PROMIS-SD), GAD-7 (every 2 weeks), and Perceived Stress (PSS-10; monthly). The PSS-10 will replace the PSS-4 on Days 0, 28, and 56. No tAN treatment will be delivered during the Baseline Period (days between Study Introduction and Day 0). Participants will complete the weekly set of questionnaires ("Weekly Questionnaires") on Day 0. Participants will be recommended to complete the daily set of questionnaires ("Daily Questionnaires ") on the other days of the Baseline Period. On Days 1 - 28, participants will self-administer one session of one to two hours of tAN therapy each day. Participants will be recommended to complete the daily tAN session post-shift prior to sleep. Weekly Questionnaires will be completed by participants on Study Days 0, 7, 14, 21, 28, 35, 42, 49, and 56. Participants will be recommended to complete Daily Questionnaires on all other study days, up to Day 28. Daily Questionnaires will not be required to be completed by participants. Daily tAN sessions and Daily Questionnaires will cease after Day 28. Participants will complete a Study Satisfaction Questionnaire with the Weekly Questionnaires on Day 56. Following Day 56, participants will schedule a Study Exit Interview with the Research Coordi
Primary Outcome
The GAD-7 is a valid and efficient tool for screening for GAD and assessing its severity in clinical practice and research. The questionnaire consists of 7 questions in which participants are asked to rate each item on a 0 (not at all) to 3 (nearly every day). GAD-7 total score for the seven items ranges from 0 to 21 where 0-4 represents minimal anxiety, 5-9 represents mild anxiety, 10-14 represents moderate anxiety and 15-21 represent severe anxiety.
