Adjunctive Habit Reversal Therapy in Treatment of Lichen Simplex Chronicus (Neurodermatitis): A Comparative, Pilot Study.

Background and Objectives: Lichen simplex chronicus (LSC) is a common dermatosis with a habitual itch-scratch cycle and associated psychological elements. Therefore, psychological methods, such as habit reversal, to break the scratching behaviour may have a therapeutic benefit in this condition. Our objective in this study was to assess additional clinical effects of habit reversal therapy when combined with standard therapeutic measures (i.e. topical corticosteroids, antihistamines, and emollients). Patients and Methods: Thirty-four patients with LSC were divided into two groups: group A (standard therapy with adjunctive habit reversal therapy, the intervention group) and group B (standard therapy alone). The patients were taught the habit reversal therapy and followed up for 4 months. Clinical assessment and Dermatology Life Quality Index (DLQI) questionnaire were performed at every visit. Results: In various parameters of LSC, including induration, skin markings, itching, and scratching, a significantly better response was seen in group A. Group A also had a better DLQI score. Patients' perception of the psychological intervention was good. Conclusions: The addition of habit reversal therapy with standard treatments of LSC significantly improved the treatment outcome. Therefore, combining psychological interventions with approved therapies may benefit chronic dermatological conditions in appropriate clinical settings.
