Abstract
Notwithstanding advances in the treatment of anxiety disorders, many patients show incomplete symptom remission following even state-of-the-art (psycho)therapy. Moreover, many people suffering from anxiety do not seek treatment at all. Self-help is increasingly regarded as a low-threshold approach to fill the apparent treatment gap. Our review summarizes the expanding but still small literature on self-help and Internet interventions for obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD) suggesting that self-help rooted in evidence-based concepts is a promising clinical tool that may aid and facilitate face-to-face treatment.
