Psychological Interventions Are More Effective Than Educational Interventions at Improving Atopic Dermatitis Severity: A Systematic Review

We determined which educational and/or psychological interventions were most effective in atopic dermatitis (AD). A systematic review of published studies evaluated the effectiveness of educational and/or psychological interventions in MEDLINE, Embase, SCOPUS, LILACS, Cochrane, China National Knowledge Infrastructure, Taiwan Electronic Periodical Services, and CiNii. Two reviewers conducted title/abstract, full-text review, and data extraction. Twenty-four prospective studies were included, including 20 randomized controlled trials. Educational (4/7 studies) and combined educational and psychological (5/6 studies) interventions reduced AD severity; psychological (10/11 studies) interventions showed the greatest benefit. The most commonly studied psychological intervention was habit reversal training (8/11 studies), which was most frequently incorporated in studies that reduced AD severity (8/10 studies). The most commonly studied educational interventions were education on AD triggers (7/7 studies) and skin care (7/7 studies); they were incorporated in all studies that reduced AD severity. Different psychological and/or educational interventions successfully reduced AD severity, especially habit reversal training
