About

Atopic dermatitis (AD) is highly prevalent and leads to suffering for the individual, increased risk of depressive symptoms and anxiety, and high societal costs. A few psychological treatment have been tested for AD, but to our knowledge none of them have been built on recently developed methods for optimizing exposure treatment. In addition, access to psychological treatment is limited and there is a need for new methods that could be easily disseminated. One possible solution to this problem is to deliver psychological treatment via the Internet, which has been tested in more than 100 randomized trials with good results for other clinical disorders than AD. The aim of this study was to test the effects of Internet-delivered mindfulness and exposure treatment (I-MET) for AD in a randomized controlled trial. We hypothesized that I-MET would lead to larger reductions of AD symptoms as well as psychological symptoms compared to treatment as usual.

Full description

Atopic dermatitis (AD), characterized by chronic itching and inflammation, is highly prevalent and leads to suffering for the individual, increased risk of depressive symptoms and anxiety, and high societal costs. Several behavioral factors are likely to play a role in the exacerbating AD symptoms over time, not least scratching, which may lead to rupture in the skin barrier and an increased risk of inflammation, which in turns increases AD symptoms. AD is also associated with avoidance behaviors that may have negative longer-term effects. With this in mind, psychological treatment based on exposure may be a logical method to achieve improvements. A few psychological treatments have been tested for AD, but to our knowledge none of them have been built on recently developed methods for optimizing exposure treatment. In a recently conducted pilot study we showed that exposure treatment, in combination with mindfulness training, can be associated with improvements for persons with AD. One challenge regarding psychological treatment is that accessibility is limited and there is a need for new methods that could be easily disseminated. One possible solution to this problem is to deliver psychological treatment via the Internet, which has been tested in more than 100 randomized trials with good results for other clinical disorders than AD. Internet-based treatment can be described as a form of online bibliotherapy where the individual is guided by a therapist who provides feedback on homework assignments. The aim of this study was to test the effects of Internet-delivered mindfulness and exposure treatment (I-MET) for AD in a randomized controlled trial. We hypothesized that I-MET would lead to larger reductions of AD symptoms as well perceived stress, sleep problems, depressive symptoms, general anxiety, and improved self-rated health, compared to treatment as usual.
