Outcomes

Primary Outcomes

Objective and Subjective Scoring of Eczema Severity

Change in eczema severity was assessed using SCORAD (SCOring of Atopic Dermatitis). A. First, the spread of eczema on different body areas is assessed by the investigator and calculated as a percent, where the maximum is 100%. B. Second, the intensity of skin redness, swelling, oozing, scratch marks, skin thickening and dryness is scored by the investigator from 0 to 3, where 0 is none, 1 is mild, 2 is moderate, and 3 is severe. C. Finally, for the subjective score, participants are asked to report the intensity of symptoms (itch and sleeplessness) from 0 to 10, where 0 is no itch or no sleeplessness, and 10 is the worst imaginable itch or insomnia sleeplessness. The total score of the objective SCORAD is obtained with the following formula: SCORAD = A/5 + 7 B/2 + C

Time frame: 8 weeks

Localized Eczema Severity

Change in localized eczema severity is assessed with the Eczema Area and Severity Index (EASI). Skin redness, elevation, scratching, and thickening are assessed by the investigator on a scale of 0 to 3, where 0 is none, 1 is mild, 2 is moderate, 3 is severe. The localized EASI is the sum of these scores.

Positive and Negative Affect

Change in mood is assessed with the PANAS-SF (Positive and Negative Affect Schedule- Short Form).
