NCT06427122

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Skindex-29

    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.

    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).

Secondary Outcomes (6)

  • 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).

  • Investigator Global Assessment (IGA)

    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).

  • EQ-5D-5L

    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).

Study Arms (2)

EMD-U

EXPERIMENTAL

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.

Behavioral: EMD Protocol for UrgeOther: Care as Usual

Care as Usual

ACTIVE COMPARATOR

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.

Other: Care as Usual

Interventions

During the EMD-U sessions, the patient is asked to focus on the spot on his/her skin where the urge to scratch is highest. The patient is asked to rate the level of urge to scratch this spot on a 10-point scale and to imagine that they scratch this spot as they would like. At the same time eye movements are offered for 30 seconds. This procedure is repeated until the level of urge to scratch has become nihil. This procedure is repeated for all other skin parts where the patient experiences an urge to scratch, until there are no skin parts left. As a homework assignment straight after the first session, the patient is instructed and encouraged to practice the same intervention at home. The two EMD-U sessions and two phone calls, take place in the first three weeks of the study. In the five following weeks, patients are phoned twice to ask for their experiences with the practicing at home.

EMD-U

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.
