Overview

AI-generated summary, not a substitute for reading the source.

This paper outlines the protocol for a randomized controlled trial evaluating a smartphone-based video intervention called SPSRS, which delivers positive word stimulation to individuals with subthreshold depression. The study involves 400 participants assigned to either the experimental group receiving daily 10-minute videos or a waiting-list control group over five weeks. Primary and secondary outcomes measure changes in depressive symptoms and psychological distress using standardized scales.
