Abstract
Anxiety-a prevalent mental health issue-is on the rise, leading to physical health problems, burnout, and societal challenges. Technological advances and limited mental health care have driven individuals toward self-monitoring devices, with biofeedback emerging as a key method for emotional regulation. Electrodermal biofeedback-though widely used-has shown mixed results in stress and anxiety management. Moreover, measurement sites for self-monitoring devices tend to be non-traditional sites such as the wrist. This study aims to assess the feasibility of a one-time electrodermal biofeedback session on state anxiety and evaluate the wrist as a viable feedback site. A randomized controlled primary study (N = 110) and a follow-up study (N = 39) to confirm the results of the first study were conducted. Participants were randomized into control, feedback from fingers and feedback from the wrists conditions followed by a 10-min biofeedback session. Our results confirm the efficacy of a 10-min biofeedback session on self-reported state anxiety and skin conductance level, response amplitude and the number of non-specific responses. We found no significant differences between feedback received from the wrists, and feedback from the fingers. Additionally, our findings suggest that skin conductance level, response amplitude and the number of non-specific responses do not show a clear relationship with self-reported anxiety. In conclusion, there is evidence of feasibility of electrodermal biofeedback in managing state anxiety, and the wrist shows promise to be a viable site for biofeedback in anxiety management. Future research should explore the interactions between electrodermal activity and self-reported measures of anxiety to optimize biofeedback interventions.
