Kintsugi Voice Device Pilot Study

Depression affects approximately 30% of people every year in the United States. Detecting mental health conditions early can help patients get the help they need sooner. Machine Learning Devices may be one way to help clinicians identify patients with mental health conditions. Clinicians may then be able to help patients receive the right level of care earlier. Many researchers are working to increase mental health screening. Machine Learning can detect subtle patterns like changes in the voice when someone is experiencing mental health conditions. Changes in the voice associated with a mental health condition are voice biomarkers.

The purpose of this study is to find correlations between voice and how people sound with clinical diagnoses. Kintsugi Mindful Wellness, Inc. has developed a tool, the Kintsugi Voice Device, that assesses mental health and conditions like depression by studying the voice. The study's goal is to test the ability of the Device to identify depressive symptoms.

Up to 500 people will take part in this research. Subject recruitment is expected to take up to 1 year. Completion of the study activities may take about 2 hours but subjects may stay enrolled for up to 2 weeks based on clinician availability for scheduling the Structured Clinical Interview for DSM-5 (SCID) interview.

Study participants will:

• Answer brief self-reported eligibility confirmation questionnaires. These answers help the researchers understand participant health history.
• Schedule a teleconference with a licensed Clinical Psychologist to evaluate their mental health over Zoom. The Clinical Psychologist will guide participants through the Structured Clinical Interview for DSM-5 Clinical Trials Version (SCID-5-CT). The Clinical Psychologist will be licensed in the participant's state of residence. This assessment will be video and audio recorded for quality assurance purposes. If participants do not agree to being videotaped and/or audio recorded, they will be unable to join the study. The SCID-5-CT assessment is for research purposes only and is not intended for treatment purposes. The results of the SCID will not be shared with participants.

On the day of the teleconference with a licensed Clinical Psychologist participants will:

• Complete three brief self-assessment surveys asking about their electronic device, mental health and quality of life: the Patient Health Questionnaire-9 (PHQ-), Generalized Anxiety Disorder-7 (GAD-7), and the World Health Organization Quality of Life (WHOQOL). These assessments will take approximately 15 minutes in total.
• Participants will provide an audio recording in response to 3 prompts of their choosing. The audio recording will be inputted to the Kintsugi Voice Device to receive a prediction of current signs of depression. The Kintsugi Voice Device Prediction is for research purposes only and will not be shared with participants.
• Complete the SCID-5-CT while being videotaped and audio recorded with a licensed psychologist or psychiatrist and participant responses will be recorded. The SCID will allow the clinician to assess participants' current mental status.

This study is intended for research purposes and is not intended for treatment and/or diagnostic purposes. The risks to this study are minimal and/or temporary and short lived. The study team has implemented procedures to minimize them wherever possible. There is always the potential for breach of confidentiality. To minimize this risk, all entries are encrypted. Researchers de-identify personal information using IDs. Researchers will store all data in a secure, password protected database and Google Cloud Platform bucket. Participation may bring up emotional content which could temporarily impact mood. To minimize this risk, everyone will be emailed a list of mental health resources.

There is no cost to subjects for participation. There may be no direct benefit from participation. Indirect benefits may include reduction in stress, learning more about mental health. Knowledge gained from the study could potentially benefit patients in the future.
