Long-Term Outcomes of Unguided Internet-Based Cognitive Behavioral Therapy: One-Year Follow-up of a Randomized Controlled Trial

The control group improved in depression, but not anxiety. Although many individuals improve over time without intervention, unguided self-help may provide faster, sustainable improvement.
