What this trial studies
This 21-day micro-randomized trial uses a just-in-time adaptive intervention (JITAI) delivered via smartphone with six brief assessments per day. Each day participants are randomized across four conditions: vulnerability-triggered, vulnerability-and-receptivity-triggered, support-need-triggered, or no-intervention control. Primary outcomes are daily depressive symptoms and received social support, with secondary outcomes of daily loneliness and perceived social support. The trial compares the relative effectiveness of three different triggering strategies to identify the best timing for delivering support prompts.
Who should consider this trial
Good fit: Adults aged 18–70 who are seeking outpatient psychotherapy, report elevated depressive symptoms (BDI-II > 13), own a smartphone, and can provide informed consent are ideal candidates, provided they are not scheduled to start therapy within four weeks and do not meet exclusion criteria.
Not a fit: People with imminent psychotherapy starts (within four weeks), significant suicidal ideation, manic symptoms, shift workers, or those without a smartphone are unlikely to benefit from this JITAI.
Why it matters
Potential benefit: If successful, the intervention could offer a low-burden smartphone tool to reduce day-to-day depressive symptoms and strengthen social support for people waiting for therapy.
How similar studies have performed: Previous JITAI and ecological momentary intervention studies in mental health have shown promise for reducing symptoms and improving support, but direct comparisons of multiple triggering strategies in this population are novel.
