Brief Summary
Approximately 200 Participants with mild-to-moderate, untreated depression and/or anxiety will be randomly assigned (by chance, like flipping a coin) to 1 of 3 study groups: Lumen Coached Problem-Solving Treatment (PST) (n=100), Human Coached PST (n=50), and optional (delayed) Lumen Coached PST as waitlist control (n=50) to improve emotional health. All participants will complete assessments at baseline and at 18 weeks post randomization. Depending on the group assignment the PST program will be delivered by Lumen, a virtual voice-based coach on a study iPad, or by a human coach in person for the first session and then via videoconference or phone for the remaining 7 sessions. Participants assigned to the waitlist control group can receive the Lumen coached PST on a study iPad after completing their 18-week follow-up assessment. Participants will receive 8 coaching sessions to learn problem-solving skills and work on unresolved problems in daily living that may be interfering with their emotional well-being and contributing to depression and anxiety symptoms.

Outcome Measures
Primary Outcomes (1)
Change from Baseline Functional Magnetic Resonance Scan at 18 weeks
Outcome Description Two neural targets defined a priori, specifically activation of the amygdala for nonconscious threat-related emotional reactivity and activation of the DLPFC for cognitive control will be assessed using fMRI. The right DLPFC is the primary neural target, while the left DLPFC and bilateral amygdala are secondary neural targets. In the facial emotion viewing paradigm, facial expression stimuli are standardized black and white photographs of 8 identities (4 female, 4 male) with evoked expressions of threat-related emotions (fear, anger), loss-related emotions (sadness) and reward-related emotions (happiness), along with neutral. For the Go-NoGo paradigm, the 'Go' and 'NoGo' stimuli are presented for 500 ms each with an inter-stimulus interval of 750 ms. The 2 paradigms are empirically validated probes of emotional reactivity and cognitive control, respectively.

Study Arms (3)
Group 1: Lumen Coached Group
ACTIVE COMPARATORParticipants in this group will attend an Intervention Orientation session to receive the Coach Lumen tutorial, a study iPad, and a Lumen Intervention Workbook. They will complete 8 PST sessions with Coach Lumen using their study assigned iPad at home over 12 weeks. The first 4 sessions occur weekly and then the last 4 occur every other week. Participants will receive automated reminders on the day before and on the day of their scheduled session, and have the opportunity to reschedule sessions through the iPad. Participants will work with Coach Lumen to learn problem-solving skills to address current life challenges, plan activities, and complete home activities. Participants will also complete surveys before and after each PST session: a mood assessment survey before and a user experience survey after. At the end of study, Participants may be invited to provide their perspective regarding their Lumen use experience.
Group 2: Human Coached Group
ACTIVE COMPARATORParticipants in this group will receive a study iPad and Human-Coached Intervention Workbook and will complete the first of 8 PST sessions in person with a trained health coach. Participants' first PST session will be in person for approximately 1 hour. Participants will complete the remaining sessions remotely via Zoom (or by phone, if necessary) using their study iPad. The first 4 sessions occur weekly and then the last 4 occur every other week. Participants will receive automated reminder notifications on the day before and on the day of their scheduled session, and have the opportunity to reschedule sessions with their coach. Participants will also complete a mood assessment survey at the beginning of each PST session. Participants will work with their health coach to learn problem-solving skills to address current life challenges, plan activities, and complete home activities.
Group 3: Optional (Delayed) Lumen Coached Group
PLACEBO COMPARATORParticipants assigned to this group can choose to attend a Lumen Orientation session to receive training and a study iPad to complete 8 PST sessions with Coach Lumen after their follow-up assessment at 18 weeks. They will receive 8 Sunday mood assessment surveys to complete (4 every Sunday and then 4 every other Sunday).
Interventions
Lumen Intervention Orientation. Participants in the Lumen intervention arm attend a Lumen orientation visit (60 minutes) during which they will be given a Lumen intervention tutorial and receive a study iPad, configured to limit access to only the Lumen intervention enabled on the device. Before leaving, participants are scheduled for the first PST session with Coach Lumen. At the end of each PST session, participants are prompted to schedule their next session with Coach Lumen. They receive automated reminder notifications 1 day prior to their next session, on the session day, and have the opportunity to make up missed sessions. As needed, Lumen intervention orientations can be done remotely.
Participants in the human coached PST arm will serve as active treatment controls given the demonstrated efficacy of human coached PST in depression and anxiety. They will complete 8 PST sessions with a human coach; first session in-person and remaining sessions via videoconferencing (i.e., Zoom preferred; with phone calls allowed) on the same 4 weekly and then 4 biweekly schedule as that for Lumen participants. Participants will receive a study iPad to use for their PST sessions via zoom. Participants also complete the PHQ-9 and GAD-7 during each session. Participants will receive a certificate of completion.
Waitlist control participants will only complete assessments during the 18-week trial period. At the end of their 18-week assessment, they will have the option to complete 8 PST sessions on their assigned iPads.
