简要总结
The primary objective of this open randomised controlled trial is to assess the add-on effect of EMD-U compared to CAU alone, in improving dermatology-specific quality of life in patients with atopic dermatitis or prurigo nodularis who suffer from severe scratching behaviour.
The main study parameter is the difference in treatment effect between EMD-U and CAU at T2, measured with the Skindex-29 symptoms scale. There are five measurement points: T0, T1 after 4 weeks, T2 after 8 weeks, T3 after 12 weeks, and T4 after 6 months.
Patients are randomly allocated to either the EMD-U or CAU condition.
详细描述
Rationale: The EMD protocol for urge (EMD-U) is a recently developed treatment that combines elements of Eye Movement Desensitization and Reprocessing (EMDR) therapy, Cognitive Behaviour therapy, and hypnotherapy. EMD-U aims to reduce the urge for scratching behaviour through desensitization techniques, self-registration of behaviour, and homework assignments. The EMD-U treatment has shown promising results in reducing scratching behaviour in patients with atopic dermatitis and is currently being investigated in patients with prurigo nodularis. Yet, the added value of the brief EMD-U intervention in addition to the care as usual (CAU) in improving dermatology-specific quality of life is unknown.
Objective: The primary objective of the study is to assess the add-on effect of EMD-U compared to CAU alone, in improving dermatology-specific quality of life in patients with atopic dermatitis or prurigo nodularis who suffer from severe scratching behaviour.
Study design: An open randomised controlled trial, with two arms: 1) EMD-U, 2) CAU (control). There are five measurement points: T0, T1 after 4 weeks, T2 after 8 weeks, T3 after 12 weeks, and T4 after 6 months.
Study population: Patients with atopic dermatitis or prurigo nodularis who suffer from substantial scratching behaviour.
Intervention (if applicable): Patients are randomly allocated to either the EMD-U or CAU condition.

研究组 & 干预措施
EMD-U
The EMD-U treatment lasts eight weeks, in which two EMD-U sessions of 60 minutes and two phone calls take place in the first three weeks. In the five following weeks, patients are phoned twice to ask for their experiences with the practicing at home. An important part of EMD-U consists of homework exercises. These homework exercises comprise to practice/apply the intervention as learned during the sessions with the therapist, in those situations wherein the urge to scratch their skin is present. In the text below, we will explain in more detail what the treatment protocol entails. Patients in this condition receive the EMD-U treatment in addition to the care as usual.
干预措施: EMD Protocol for Urge (Behavioral)
Care as Usual
Patients in the control group receive care as usual (CAU), which is the standard care of the dermatologist. In addition to completing the questionnaires at T0, 1, 2, 3, and 4 these patients are not offered any additional treatment or support aimed at their scratching behaviour.

结局指标
主要结局
Skindex-29
时间窗: measured at the start of the study (T0), in week 4 (T1), in week 8 (T2), and during follow-up, in week 12 (T3) and six months after T0 (T4).
The main study outcome is the dermatology-specific health-related quality of life (HRQOL). It consists of 30 items to be scored on a 5-point response scale. Outcome ranges from 0 (never) to 100 (all the time). The sum of scores is devided by the number of items answered. Higher scores indicate worse quality of life. The instrument has three subscales: symptoms, emotions, and functioning.

- Eczema Area and Severity Index (EASI)(Measured at the start of the study (T0), in week 4 (T1), in week 8 (T2), and during follow-up, in week 12 (T3) and six months after T0 (T4).)
- The Self-Control Cognition Questionnaire, Dutch: Zelfcontrole Cognitie Vragenlijst (ZCCL)(Measured at the start of the study (T0), in week 4 (T1), in week 8 (T2), and during follow-up, in week 12 (T3) and six months after T0 (T4).)
- Patient Health Questionnaire for anxiety and depression (PHQ-4)(Measured at the start of the study (T0), in week 4 (T1), in week 8 (T2), and during follow-up, in week 12 (T3) and six months after T0 (T4).)
