NCT04985422 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 262

No results posted yet for this study

Summary

The key aim of the study is to test the efficacy of a 4-week ecological momentary intervention (EMI), as compared with the regular weekly-based intervention (control group), in reducing (1) symptoms of depression and (2) rumination in community-dwelling individuals. The efficacy of the EMI in reducing distress and improving functioning is also examined.

For both EMI and control groups, the intervention will be delivered through SMS text messages, with a link to a user-friendly and locally-adapted intervention platform designed using Qualtrics (online survey programme).

It is hypothesised that (1) those in the EMI group, as compared to the control group, will show greater reductions in (1) depressive symptoms, (2) rumination level, (3) distress, and in (4) improving functioning. These effects are hypothesised to be observed in individuals with varying levels of symptom severity.

Conditions

  • Depressive Symptoms

Interventions

BEHAVIORAL

Smartphone-based Daily Ecological Momentary Intervention

Interventions are delivered through smartphones (SMS text message + Qualtrics) at a low cost with high accessibility. Participants are prompted 6 random times a day over the set intervention period (4 weeks) to complete brief EMA and EMI intervention actions) across contexts in daily lives for the reduction of depressive symptoms, as well as rumination distress, and improve functioning.

BEHAVIORAL

Smartphone-based Weekly-delivered Information

Information with simple actions for reducing depressive symptoms are delivered through smartphones (SMS text message + Qualtrics) at a low cost with high accessibility. Participants are prompted weekly with a new set of information, together with a 5-min assessment. The information includes intervention actions provided in the EMI group.
