What SSI Duration is Most Effective? An Online Experiment With American Adults

Completed · Not applicable

Conditions studied: Depression

In brief

In a previous study (https://osf.io/qdznc), the research team found that an 8-minute version of a single-session intervention for loneliness was more effective than a 23-minute version of it. The present work aims to further explore the relationship between intervention duration and effectiveness. In this online trial, participants will be randomized to a 15-minute single-session depression intervention called the Action Brings Change (ABC) Program, a 10-minute version of it, a 6-minute version of it, or a 2-minute version of it. The main analysis will evaluate how change in depressive symptoms over eight weeks differs across conditions.
