This clinical trial intends to study the efficacy of a mobile phone delivered intervention in reducing depression-related rumination.
Here we propose to test a novel intervention to help individuals manage their depressive rumination. The intervention is based on a just-in-time, adaptive-intervention (JITAI) design. A JITAI is "an intervention designed to address the dynamically changing needs of individuals via the provision of the type/amount of support needed, at the right time, and only when needed ." This study is also to address one major concern regarding designing JITAI interventions: the burden on participants in having to be engaged with the intervention through diaries, self-reports, and other forms of assessment procedures daily. To reduce this burden, we first pilot test an interactive narrative form. An interactive narrative is an essential form of storytelling that involves certain interactive features such that audiences or readers of the story can have the feeling that they are actively engaging in certain forms of interactions with the story characters.
To test the efficacy of such an intervention, there will be a one-month three-arm clinical control trial to reduce depressive rumination. There are three conditions: a JITAI interactive narrative condition, a non-narrative JTIAI condition, and a wait-list control condition. This study could contribute to our knowledge in designing more effective interventions in curbing depression using mobile technology. It can also advance our theoretical knowledge of the role of interactive narratives in reducing user burden in mobile health.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| a JITAI interactive narrative condition (Narrative JITAI) | Experimental | This arm is an exploratory condition, which tested whether story-based JITAI would be an effective way to deal with rumination. |
|
| a JITIAI non-interactive condition | Experimental | This arm uses the regular JITAI ( mobile phone delivered) intervention to provide treatment for ruminative thoughts. |
|
| a wait-list control condition | No Intervention | Participants in this arm will be put on a waitlist without receiving active treatment upon the end of the study. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Mobile-phone delivered Treatment for Excessive Rumination | Behavioral | This is a one-month three-arm clinical control trial to reduce the rumination and interpersonal impairment link. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Rumination focus ( immediately after intervention) | Momentary Ruminative Self-Focus Inventory-Abbreviated (MRSI-A). The MRSI is a 6-item questionnaire measuring state-level fluctuations in ruminative self-focus. Each item ranges from 1 (Strongly disagree) to 7 (Strongly agree). | Change in Rumination focus at the baseline and immediate-post intervention (measured baseline, immediate-post intervention, and two-week follow-up). |
| Change in Rumination focus ( two weeks after intervention) | Momentary Ruminative Self-Focus Inventory-Abbreviated (MRSI-A). The MRSI is a 6-item questionnaire measuring state-level fluctuations in ruminative self-focus. Each item ranges from 1 (Strongly disagree) to 7 (Strongly agree). | Change in Rumination focus at the baseline and two weeks after the intervention (measured baseline, immediate-post intervention, and two-week follow-up). |
| Change in Heart-rate( baseline and immediately after intervention) | Participants self-report their heart-rate by using a moblie phone app by the name of Instant Heart rate (see example outcome report: https://www.azumio.com/heartrate/report.jsp?token=28928192047-28935807244-3eb659-334dc9f600fc7084f8cda95b135396673b2bd118-1588095873083#) | Change in heart rates at the baseline and immediate-post intervention .(measured baseline, immediate-post intervention, and two-week follow-up) |
| Change in Heart-rate (baseline and two weeks after intervention.) | Participants self-report their heart-rate by using a moblie phone app by the name of Instant Heart rate (see example outcome report: https://www.azumio.com/heartrate/report.jsp?token=28928192047-28935807244-3eb659-334dc9f600fc7084f8cda95b135396673b2bd118-1588095873083#) | Change in heart rates at the baseline and two weeks after the intervention (measured baseline, immediate-post intervention, and two-week follow-up). |

| Measure | Description | Time Frame |
|---|---|---|
| Change in Ruminative symptom ( baseline and immediately after intervention) | To measure this, we will use the ruminative response scale (RRS), a self-report measure of describing one's responses to depressed mood. It has 22 items, ranging from 1 (not like me at all) to 7 (A lot like me). | Change in ruminative symptoms at the baseline and two weeks after the intervention (measured baseline, immediate-post intervention, and two-week follow-up). |
