An interventional study of Vira mobile app intervention and Vira mobile app intervention + coaching in Mental Health Disorder, Obesity and Overweight, sponsored by Ksana Health. Completed at 1 site in United States. Open to participants aged 18 Years to 25 Years. Per ClinicalTrials.gov, last updated 2023-05-18.
Sponsored by Ksana Health · Not applicable, Interventional, and Prevention
The goal of this study is to test the feasibility and utilization of a redesigned mobile app and health coaching platform (Vira) in youth (aged 18-25 years) with elevated depressive symptoms who are overweight/obese and/or self-report parental history of overweight/obesity.
Eligible participants will be randomly assigned to one of two groups: one group will use the Vira mobile app intervention with support from a health coach, and the other group will use the Vira mobile app intervention without coaching. Both groups will use the app for 12 weeks.
The primary aim of this project is to examine the feasibility and utilization of a redesigned mobile app and health coaching platform (Vira) in a 2 x 2 (gender x condition) designed pilot study in a sample of 100 youth (18-25 years old) with (1) elevated depressive symptoms (PHQ-8 score ≥10) and (2) overweight/obesity (BMI ≥ 25 and/or reporting a parental history of overweight/obesity). The study will examine the feasibility and utilization of the mobile app intervention with coaching compared to that of the mobile app intervention without coaching.
This is an exploratory pilot study; therefore, no formal sample size calculation was conducted. It is anticipated that 1,000 individuals will be screened, of which 20% will be eligible, and that 50% of those eligible will agree to participate (final N = 100, 50 per arm).
1,740 studies on the registry are indexed under Mental Disorders; 348 are open to participants now.
This study's enrollment of 73 is below the median of 100 across 1,301 interventional studies indexed under Mental Disorders.

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

The Vira app is installed on the participant's phone. The app passively collects data from phone sensors (i.e., measures of physical activity, sleep patterns, mobility, and language patterns reflecting mood states and cognition) that are indicative of risk-relevant behavioral patterns and psychological states. It also so prompts users to answer a daily check in question. Mobile sensing data are processed to provide an automated assessment of the user's functioning. Users will be asked to use Vira for 12 weeks. The Vira app can be used as a standalone product. After an initial 10-day period, during which the app assesses the relationship between the user's patterns of behavior and their day-to-day variations in mental health and wellbeing using passive mobile sensing, the user is able to access a personalized behavior change goal that is support by in app information and functionality.
Behavioral: Vira mobile app intervention
The Vira app can also be supported by a health coach. The health coach interacts with the user (via an instant messaging platform) and who also schedules just-in-time reminders (i.e., "nudges") to arrive in the user's phone at scheduled times to support their behavior change plan. The Vira Health Coach Platform therefore integrates mobile sensing, self-report assessment, and just-in-time nudges and notifications into the coach's workflow.

Change in depressive symptoms
Pre- to post-intervention changes in depressive symptoms will be assessed by the Patient Health Questionnaire (PHQ-8) an 8-item participant-report measure for screening for depression and for establishing depression severity. The total score ranges from 0-24, with a higher score indicating greater depression symptom severity.
Time frame: 12 weeks
Number of active days in the Vira mobile app intervention and health coaching platform
To measure feasibility of implementation, the total number of active days using Vira during the study will be objectively collected via the Vira platform.
Time frame: 12 weeks

To measure feasibility of implementation, the total number of features used during the study will be objectively collected via the Vira platform.
Time frame: 12 weeks
Acceptability of the mobile app intervention
Acceptability of the mobile app intervention and health coaching platform will be assessed using 11 items adapted from the Technology Acceptance Model. Scores range from 11 to 77, with higher scores indicating greater acceptability.
Time frame: 12 weeks

Ran from Nov 2022 to primary completion in May 2023, 5 months.
Of 680 interventional studies with no phase under Mental Disorders, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 45. This study's 5 months is below that.
Mental Disorders covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.
