Introduction: Internet computer-based psychological treatments have enjoyed rapid growth. Today, there are a number of them available for many mental disorders and psychological problems. Internet-based psychological treatments for anxiety disorders and phobias are amongst the most frequently observed. Treatment results with these resources are promising, but inconclusive.
Methods: This paper reviews 11 systematic reviews and meta-analyses about the efficacy of Internet-based psychological treatments for anxiety disorders, including studies and clinical trials covering the majority of anxiety disorders and phobias, usually with adult patient samples.
Results: In general, these reviews agree on the efficacy of Internet-based psychological treatment as compared with non-treatment groups (with large effect sizes), finding similar efficacy compared with face-to-face therapies. Internet-based psychological treatments are further improved when combined with some type of therapist contact. On the negative side, some systematic reviews highlight high attrition rates of Internet-based psychological treatments.
Discussion: These findings remain inconclusive and more refined reviews (involving patient samples, therapy comparisons, type of therapist contact, etc.) are needed, in order to establish the scope and limits of Internet-based psychological treatments for anxiety disorders.
Keywords: Internet computer-based psychological treatments; anxiety disorders; review.
