One solution to address the scalability gap is via internet-based or e-therapy. Internet-CBT for depression has comparable efficacy to face-to-face treatment when supported by a therapist 17], can increase access by removing time constraints and geographical restrictions to attending therapy[7], and can increase cost-effectiveness and treatment coverage[8] by reducing therapist treat- ment time. Effective unguided e-therapy would have almost no constraints on volume of use and would be globally scalable and accessible
