IMPORTANCE: Atopic dermatitis is a common and debilitating skin condition characterized by intense itching and chronic inflammation. Research on behavioral treatments with high accessibility is needed. OBJECTIVE: To investigate the efficacy of a highly scalable internet-delivered cognitive behavior therapy (CBT) for adults with atopic dermatitis. DESIGN, SETTING, AND PARTICIPANTS: This randomized clinical trial from a medical university in Stockholm, Sweden, included 102 adults with atopic dermatitis, recruited from across Sweden, who received 12 weeks of internet-delivered CBT (March 29, 2017, to February 16, 2018). The first participant provided screening data on November 27, 2016, and the last 1-year follow-up assessment was conducted on June 28, 2019. INTERVENTIONS: Participants were randomized in a 1:1 ratio to 12 weeks of therapist-guided internet-delivered CBT (n = 51) or a control condition (n = 51) that gave instructions about standard care. MAIN OUTCOMES AND MEASURES: The primary outcome was the between-group difference in mean reduction of atopic dermatitis symptoms as measured by the Patient-Oriented Eczema Measure and modeled intention to treat during the 12-week treatment period. RESULTS: A total of 102 participants (mean [SD] age, 37 [11] years; 83 [81%] female) were recruited and randomized. The primary analysis indicated that participants receiving internet-delivered CBT, relative to the controls, had a significantly larger mean weekly reduction in symptoms of atopic dermatitis as measured with the Patient-Oriented Eczema Measure (B = 0.32; 95% CI, 0.14-0.49; P < .001), with a moderate to large, controlled effect size after treatment (d = 0.75; 95% CI, 0.32-1.16). Secondary analyses indicated that internet-delivered CBT also produced significantly larger reductions in itch intensity, perceived stress, sleep problems, and depression. Gains were sustained at 12 months of follow-up. Treatment satisfaction was high, and therapists spent a mean (SD) of 39.7 (34.7) minutes per treated patient providing internet-delivered CBT. CONCLUSIONS AND RELEVANCE: Internet-delivered CBT appears to be efficacious for reducing symptoms of atopic dermatitis, despite requiring minimal therapist resources. Thus, internet-delivered CBT has the potential to increase access to effective adjunct behavioral treatment for patients with this common skin condition. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03051958.
