Internet-Based Interventions are increasingly relevant as an alternative for reducing the gap in treatment of metal disorders such as depression, especially in resource-limited regions.
In this study the investigators will try to evaluate the effectiveness of an Internet-Based Intervention culturally adapted to the Ecuadorian population for treatment of depression.
Our participants will be randomized to one of the following three conditions: 1) Internet-Based intervention (IBI) with automated support (e.g. e-mails or text messages), 2) IBI plus human support by phone calls (automated + human support), 3) Waiting list control group .
The corresponding evaluations of the outcomes will be carried out at different moments of the process: baseline, three, six and twelve months.
This study will use the Smile is Fun program for the treatment of depression previously adapted to the Ecuadorian context.
