effect of emdr for reduction of pain interference in children with sickle cell disease

Conditions: Sickle Cell Disease; Pain; Pain, Chronic Disease

Summary: children with sickle cell disease may experience frequent painful episodes. this, together with the traumatic experiences during a hospitalization, can lead to the development of posttraumatic stress reactions. as the stress can trigger painful episodes (pain crisis) in children with sickle cell disease, the investigators think that treating these stress symptoms can reduce the pain-related problems in their lives. eye movement desensitization and reprocessing (emdr) is proven to be an effective trauma treatment for posttraumatic stress disorder. research studies show that emdr can reduce pain in adults. the investigators want to study now if emdr effective is in reducing pain-related problems in children with sickle cell disease.

objective: the primary objective of this study is to investigate the efficacy of emdr therapy in reducing pain interference in the lives of children with scd. secondary objectives are to study the efficacy of emdr in reducing ptsd symptoms, anxiety, depressive symptoms, physical complaints (low mobility), frequency and severity of pain, use of pain medication, and number of days absent from school. themes of pain and trauma-related memories and feasibility of emdr therapy for this population will also be explored. study design: in this single-center randomized controlled trial (rct) patients (aged 6-18 years) with scd and clinically relevant scores on promis pain interference will be randomized into an intervention group and waiting list control group. measurements will be done for the complete study population at inclusion (t0). in the intervention group, measurements will be done 2 weeks (t1i) and 3 months (t2i) after the end of emdr sessions. eight weeks after inclusion (t1c) will be performed for participants in the waiting list control group just before they receive emdr treatment, and they are asked to complete measurements, 2 weeks (t1.1c) and 3 months after the end of emdr sessions (t2c). intervention: after the intake session (week 1), including case conceptualization and treatment plan, a maximum of 6 weekly emdr sessions with a duration of 1 hour per session will be offered. the waiting list control group will wait 9 weeks before starting emdr therapy.

Eligibility criteria:
inclusion criteria: * medical diagnosis of scd * age between 6 and 18 years old * elevated pain interference scores: reporting above the clinical cut-off t-score of 49 on promis pain interference (parent-proxy version for children from 6-7 years and self-report version for children from 8 years). * having sufficient knowledge of the dutch or english languages to complete the assessments exclusion criteria: * undergone successful stem cell transplantation * pregnant adolescents * current unsafety that is likely to interfere with psychological therapy for example ongoing domestic violence * major interfering acute medical or psychiatric condition, such as psychosis, substance dependence, current severe self-harm or high risk for suicide requiring immediate treatment * receiving psychological (trauma) treatment by another therapist at the same time * iq estimated to be \< 80 based on information contained in the medical history or information from educational services/school
