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.
All participants will complete measurements of neural target engagement and treatment outcomes at both baseline (0 week) and 18 weeks. Study Visit 1: This will include (1) Physical measurements such as height, weight, and blood pressure, (2) functional magnetic resonance imaging (fMRI) scan, (3) surveys of intervention-related measures, and (4) surveys of patient-reported outcomes, such as depressive and anxiety symptoms, social functioning, and health-related quality of life. Following the successful completion of Visit 1 and all the surveys, participants will be randomly assigned (by chance, like flipping a coin) to 1 of 3 study groups, as described below. Problem Solving Treatment (PST) Groups Group 1: Lumen Coached Group : Participants assigned to 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 (4 weekly and then 4 biweekly) with Coach Lumen at home over 12 weeks. Group 2: Human Coached Group Participants assigned to this group will receive a study iPad and Human-Coached Intervention Workbook, and will complete 8 PST sessions (4 weekly and then 4 biweekly) with a trained health coach over 12 weeks. They will complete the first session in person and then the remaining sessions via videoconference or phone. Group 3: Optional (Delayed) Lumen Coached Group Participants assigned to this group may choose to attend a Lumen Orientation session to receive training and a study iPad to complete 8 PST sessions with Coach Lumen after completing their follow-up assessment at 18 weeks. Regardless of the group assignment, participants will complete brief Nightly Mood Check-in surveys about their thoughts, feelings, and experiences over the day, for 7 nights, approximately every other week over 18 weeks (i.e., a total of 58 nights). These check-ins are sent via text message to their mobile phone. Study Visit 2: Regardless of group assignment, participants will be asked to attend a second in-person visit for data collection at 18 weeks. Like Visit 1, Visit 2 will include physical measurements, a brain scan (after a negative pregnancy urine test, if applicable), and online surveys (if not yet completed before the visit), and will last approximately 90 minutes.

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.

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.

Change from Baseline Hospital Anxiety and Depression Scale (HADS) at 18 weeks
HADS, including 7 questions for anxiety and 7 questions for depression, measures self-reported anxiety and depression in a general medical population of patients. Each item on the questionnaire is scored from 0-3 and the score for either anxiety or depression ranges between 0 and 21 with the following categories: normal 0-7, mild 8-10, moderate 11-14, and severe 15-21. Total score for the entire scale (emotional distress) ranges from 0 to 42, with higher score indicating more distress.

Change from Baseline Penn State Worry Questionnaire (PSWQ) at 18 weeks
PSWQ is a self-reported, 16-item, Likert-type scale that measures the trait of worry.
Time frame: Baseline, 18 weeks
Change from Baseline Positive and Negative Affect Schedule (PANAS) at 18 weeks
PANAS consists of two 10-item self-reported scales to measure positive and negative affect. Each item asks about the extent one has felt a positive or negative feeling on a 5-point scale of 1 (not at all) to 5 (very much).
Time frame: Baseline, 18 weeks
Change from Baseline Social Problem-Solving Inventory-Revised: Short Form (SPSI-R:S) at 18 weeks
Participants' problem solving abilities will be assessed using the reliable and valid SPSI-R:S that contains 25 items in the following 5 subscales: positive problem orientation (PPO), negative problem orientation (NPO), rational problem solving (RPS), impulsive/careless style (ICS), and avoidance style (AS). Each item is rated on a 5-point scale ranging from "not at all true of me" (0) to "extremely true of me" (4). SPSI-R:S is a short version of the long SPSI-R:L form.
Time frame: Baseline, 18 weeks
Change from Baseline Dysfunctional Attitudes Scale (DAS) at 18 weeks
DAS (Form A) is a 40-item self-reported scale that measures the presence and intensity of dysfunctional attitudes. Each item is rated a 7-point Likert scale (7 = fully agree; 1 = fully disagree). The higher the sum of the 40-items, the more dysfunctional attitudes an individual possesses.
Time frame: Baseline, 18 weeks
Change from Baseline Sheehan Disability Scale at 18 weeks
The Sheehan Disability Scale is a validated questionnaire that measures functional disability and is sensitive to treatment effects in clinical trials. Patients rate the extent to which their symptoms impair work/school, social, and family life on a visual analog scale from 0 to 10 and answer the number of days when their symptoms cause them to miss work/school and be unproductive at work/school.
Time frame: Baseline, 18 weeks
Change from Baseline Work productivity and activity impairment questionnaire (WPAI) at 18 weeks
The WPAI was created as a patient-reported quantitative assessment of the amount of absenteeism, presenteeism and daily activity impairment attributable to general health in the past 7 days.
Time frame: Baseline, 18 weeks
Change from Baseline Daily Mood
Daily end-of-day assessments will be captured over a one-week period at baseline and every 2 weeks (i.e., on weeks 2, 4, 6, 8, 10, 12, and 18). During active treatment in the Lumen arm and the in-person PST arm, this will occur for 3 days prior to, the day of, and for 3 days after a scheduled PST session. For waitlist controls, this will occur for 7 days starting on Sunday of each assigned week. Daily mood will be measured using 8 mood items that capture both the arousal and valence components of the circumplex model of affect.
Time frame: Baseline and every 2 weeks (i.e., on weeks 2, 4, 6, 8, 10, 12, and 18)
Change from Baseline Daily Stress
Outcome Description Daily end-of-day assessments will be captured over a one-week period at baseline and every 2 weeks (i.e., on weeks 2, 4, 6, 8, 10, 12, and 18). During active treatment in the Lumen arm and the in-person PST arm, this will occur for 3 days prior to, the day of, and for 3 days after a scheduled PST session. For waitlist controls, this will occur for 7 days starting on Sunday of each assigned week. Daily stress will be assessed by report of stressors on that day; when stress is reported, the nature/characteristics of the stressor and response will be assessed. The type of stress will be assessed using a list of 12 categories of social problems, followed by reporting the perceived severity of the most salient stressor that day, and the degree to which the participant has had stressor-related thoughts (e.g., intrusive thoughts). Finally, we will capture an overall perceived stress report for each day.
Time frame: Baseline and every 2 weeks (i.e., on weeks 2, 4, 6, 8, 10, 12, and 18)
Change from Baseline Daily Appraisal and Coping
Daily end-of-day assessments will be captured over a one-week period at baseline and every 2 weeks (i.e., on weeks 2, 4, 6, 8, 10, 12, and 18). During active treatment in the Lumen arm and the in-person PST arm, this will occur for 3 days prior to, the day of, and for 3 days after a scheduled PST session. For waitlist controls, this will occur for 7 days starting on Sunday of each assigned week. Two components of these assessments will capture a summary of appraisal and coping processes associated with daily experiences. The appraisal items will focus on assessing "problem orientation" or the general awareness and appraisals of problems during the day. The coping items will focus on assessing "problem-solving style" or the methods of planning and coping with the most salient problem experienced during the day.
Time frame: Baseline and every 2 weeks (i.e., on weeks 2, 4, 6, 8, 10, 12, and 18)
