## Research fields
### Internet treatment—the Swedish approach

Gerhard Andersson can further be named as the founder of the Swedish approach to internet-delivered cognitive-behaviour therapy (CBT). In one of the publications from the group, Andersson et al. (2008, p. 164) refer to the Internet-based approach as:"a therapy that is based on self-help books, guided by an identified therapist which gives feedback and answers to questions, with a scheduling that mirrors face-to-face treatment, and which also can include interactive online features such as queries to obtain passwords in order to get access to treatment modules."
The Swedish approach is different from purely self-administered self-help since it combines the advantages of structured self-help materials with the provision of guidance by an identified therapist. In particular, the role of the therapist is highlighted in the treatment trials conducted by Professor Andersson and his group. The therapist provides support, encouragement, motivation, and answers to patient's questions. Hence, the cognitive-behavioural treatment resembles rather a live treatment than a pure self-help treatment, but is provided via the Internet. A similar way to deliver Internet treatment has been endorsed by other researchers across the world. Despite the important role of the therapist, Internet-delivered treatments require much less therapist time than conventional CBT. Furthermore, Internet-based CBT allows patients to work at their own pace whenever they find the time to work on the material. This procedure gives a lot of responsibility to the patient, which can be helpful for the final treatment outcome. Several studies conducted by Andersson and his colleagues show a high efficacy of the Internet-based treatment approach for very different disorders, e.g. depression, social anxiety, and tinnitus. Current studies of the group compare the efficacy of Internet-delivered CBT with traditional CBT approaches, e.g. face-to-face treatment, group therapy. Due to Andersson's studies on Internet-based approaches to deliver psychotherapy, Sweden is world leading in online-based treatments. The research has generated quite a lot of media attention in Sweden, but also in other countries. Research on psychological treatments on the Internet is available from several other research groups as well.

### Tinnitus

Gerhard Andersson is one of the world leading researchers in the field of psychologically oriented tinnitus research. His contributions to the field has been influential. For example, Andersson and his colleagues provided the first comprehensive meta-analytic review on psychological treatments of tinnitus in 1999. In the following years, Andersson was interested in basic research as well as in the development and improvement of psychological treatment approaches. Thus, he studied for example cognitive disruptions in tinnitus patients, changes in regional cerebral blood flow or the role of tinnitus loudness for perceived distress. Moreover, Andersson and his colleagues developed several treatment concepts to reduce tinnitus distress based on cognitive behavioural therapy.

### Health psychology

As a clinical psychologist working in the field of behavioral medicine for 20 years, Andersson has devoted much of his research to the study of how behavioral, cognitive, biological, and social variables influence health and illness. His research in this area covers a broad range of conditions, including chronic pain, cancer, irritable bowel syndrome, dizziness, hearing loss, tinnitus, burn damages, and health anxiety. Andersson's work focuses primarily on the development and evaluation of behavioral and cognitive therapies for medical conditions, but his research in health psychology also concerns the study of how cognitive, behavioral and genetic factors are involved in health and prevention of illness. A particular interest of his is cognitive aspects and to apply various theories and methods from cognitive psychology in the study of health problems. Among many recent activities, Andersson is currently involved in studies on the role of acceptance in chronic medical conditions, including the first clinical trials on acceptance oriented CBT for tinnitus.

### Other research

Andersson is also active in research fields such as psychotherapy research and the psychology of religion. He is the editor-in-chief for the journal Internet Interventions.
