The goal of this research is to test usability and user satisfaction with a new breathing feature on the meditation app, Equa, to help young adults who are distressed, understand their physiological responses and mindfulness skill development during meditation.
Our main aims are to test an algorithm that can use physiologic signals to give feedback about how participant physiology is changing during guided lessons on the meditation app, Equa through:
Participants will:
Investigators will recruit young adults to participate in a study to examine the usability and user satisfaction of respiration biosignal feedback during meditation through phone motion data and microphones within headphones. Interested participants will be screened on study inclusion/exclusion criteria: (1) aged 18-30 years, (2) interested in coming on site to complete 14 smartphone guided mindfulness meditation training units, (3) willing to be assigned to one of two conditions, (4) willing to wear physiological monitoring equipment and provide ratings of their training experience, (5) Not currently pregnant and (6) no current or previous diagnosis of psychosis or schizophrenia
Participants are told they are going to participate in a study that focuses on monitoring physiological responses during meditation. At the start of the study, participants will complete questions via an online survey focused on demographics, prior meditation experience, their thoughts and feelings as these may be informative to participants' meditation experience.
Participants will complete a few brief questionnaires to understand potential changes in mindfulness before and after select lessons. Participant physiological data will be recorded (E.g., heart rate) via smartphones and headphones to track physiologic dynamics. Additionally, the sensory shirt, made by Hexoskin Smart Sensors; AI, will also continuously measure physiologics via two inductive plethysmography (RIP) sensors. The Hexoskin shirt also tracks motion via a three-axis accelerometer. These measures will enable investigators to better understand mindfulness measures during meditation.
Following the guided meditation lessons, a subset of participants (the experimental group) will see a graph tracking their physiological responses from the guided meditation lesson and predictive mindfulness skill scores based on our algorithm development. The feedback chart is produced by the physiological measures tracked throughout the duration of the lesson, and is displayed within the Equa app, moments after the meditation lessons concludes. The control group will not see the graph tracking their physiological responses.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control Group, No Physiological Feedback | Active Comparator | Participants be randomly assigned to one of two different 14-unit smartphone meditation program groups that involve completing a 2-10 minute daily guided practice on their phones. Participants in both groups will follow the same 14 units of mindfulness meditation curriculum that consists of learning and practicing techniques to improve concentration, sensory clarity, and equanimity (Equa meditation app) and have access to additional curriculum. Physiological measures will be tracked throughout the duration of lessons. A subset of participants (the experimental group) will see a graph tracking their physiological responses from the guided meditation lesson and predictive mindfulness skill scores based on the algorithm development. The control group will not see the graph tracking their physiology. |

| Assess usability and user satisfaction with respiration biosignal tracking and predictive mindfulness skill scores during meditation training to changes in mindfulness skills from pre-training to post-training | >85 on System Usability Scale and significantly more user satisfaction with biosignal augmented Equa. The investigators will conduct usability testing with the respiration biosignal tracking on Equa, and experimentally evaluate if Equa-augmented respiration biosignal tracking increases user satisfaction in the lab relative to Equa with no biosignal tracking. | Throughout 5 sessions over the course of 4 weeks (study completion) |

| Change from Baseline in total anxiety as assessed by the General Anxiety Disorder, 7-item questionnaire at post treatment | Participants respond to a questionnaire asking about how often they have been bothered by any of the listed problems over the last 2 weeks. Zero is equivalent to not at all (lower anxiety) and 3 indicates nearly every day (higher anxiety). | From enrollment to the end of treatment at up to week 4 |

The investigators will experimentally evaluate if Equa-augmented respiration biosignal tracking significantly increases user satisfaction relative to Equa with no biosignal tracking. Both groups will receive the 14 lessons of mindfulness meditation, however only one group (experimental) will see the respiration biosignal feedback from the algorithm developed and tested in Study 1.
