This stepped wedge, randomized controlled trial (RCT) will test the effectiveness of a digital mental health intervention (VMood) adapted from an evidence-based in-person intervention. The in-person intervention is based on principles of Cognitive Behavioural Therapy and uses a supported self-management approach consisting of a patient skills workbook and supportive coaching by a non-specialist provider. It was developed in Canada and shown to be effective in the Vietnamese context in a previous RCT conducted by the research team. The digital adaptation (VMood) is delivered via a Smartphone app the research team developed in Vietnam, in close collaboration with the Institute of Population, Health and Development (PHAD) in Vietnam.
The digital intervention will be delivered at the community level in 8 Vietnamese provinces, with remote coaching provided via the app by social workers. The primary outcome measure for the study is the Patient Health Questionnaire (PHQ-9), which screens for depression caseness. The investigators will also include the Generalized Anxiety Disorder(GAD-7) measure, as symptoms of anxiety commonly co-occur with depression. Secondary outcome measures will include the WHO Quality of Life-Brief (WHOQUAL-BREV), FAST Alcohol Screening Test (FAST), the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) adapted to assess tobacco use only. The investigators will also conduct a cost-effectiveness analysis (CEA) using the 5-level EQ-5D (EQ-5D-5L), the Health Economic Assessment (HEA) adapted for the Vietnamese health context, and Work Productivity and Activity Impairment Questionnaire: Depression (WPAID:D). Finally, the System Usability Scale (SUS) will be used to assess VMood usability.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intervention | Experimental | This arm will receive the VMood digital mental health intervention. This consists of bibliotherapy that is delivered via a smartphone app, with coaching support provided by social workers for a duration of three months. The skills in the workbook are grounded in principles of Cognitive Behavioural Therapy. |
|
| Control | Other | This arm will receive enhanced treatment as usual, which consists of regular care as provided by primary care centres and a brief introduction video about depression via the app. The control arm will receive the intervention after the intervention arm has completed the intervention period. |

| VMood | Other | VMood is a digital mental health intervention adapted from an evidence-based in-person intervention. It uses supported self-management approaches, consisting of bibliotherapy (the Antidepressant Skills Workbook) and supportive coaching from a social worker that are provided via the smartphone app. The individual is supported in the use of the skills over the course of three months. The skills in the workbook are grounded in principles of Cognitive Behavioural Therapy. |

| System Usability Scale (SUS) | To assess the usability of the VMood app. The System Usability Scale (SUS) is an industry standard, validated 10-item Likert-type scale with five response options for measuring usability with 0 (strongly disagree) to 4 (strongly agree). Item scores are summed and the total is multiplied by 2.5. The composite score (between 0 and 100) provides an indicator of perceived usability - a higher score means better perceived ease of use. Research shows a score >68 is considered above average. Though the scores are 0-100, these are not percentages and should be considered only in terms of their percentile ranking. | Three months, with a follow up at six months |
