Pain Clinical Trial

Official title: Development and Clinimetric Properties of the Dutch Pediatric Neurophysiology of Pain Questionnaire in Healthy Children

Status Completed

Clinical Trial Summary

The scientific objective of this research implies developing and examining the clinimetric properties of the Dutch Pediatric Neurophysiology of Pain Questionnaire (PedNPQ) in healthy children.

A total study sample of 60 healthy children (30 from 2nd and 3rd primary school) will be included to measure test-retest reliability of the Pediatric Neurophysiology of Pain Questionnaire (PedNPQ). Children will be asked to fill in the questionnaire twice, with a time interval of 48 hours (assessment T0 and T1).

In order to assess concurrent validity of the PedNPQ, 30 children (15 from 2nd and 3rd primary school) as well as their parent will receive a pediatric Pain Neuroscience Education (PNE) session. It is hypothesized that if the developed PedNPQ is valid, children who received PNE will perform better than children receiving no PNE.

To reduce the participant's workload, all assessments will be done immediately after the school hours or during recreation, in the primary school of the participant.

Clinical Trial Description

Pain is a common and daily experience among children that is usually short-term, causing little to moderate discomfort. Yet, a substantial number of children experience chronic pain. Persistent pain periods mainly affect the children's school attendance and participation in recreational activities, possibly leading to academic impairments and social exclusion. Even worse is the children's greater predisposition to develop chronic pain into adulthood. Considering these disadvantages, children suffering from chronic pain should be treated as fast as possible and in the most optimal way. The existing literature on management in children with chronic pain encourages a multidisciplinary approach involving physical therapy and psychological interventions (i.e. cognitive behavioural therapy).

Recently, the application of Pain Neuroscience Education (PNE) as an intervention on its own, as well as in combination with another form of therapy (such as physiotherapy or cognitive- behavioural therapy) is receiving growing interest in the pediatric field of chronic pain. PNE aims to make people understand how their pain is produced and enables them to integrate this understanding into their everyday lives and subsequent treatment components. This innovative education style has shown to be effective in various adult chronic pain populations, by improving the patients' pain coping strategies and health status, and changing their pain beliefs. Although, no study examined the effectiveness of PNE in the context of chronic pediatric pain. The hypothetical efficacy of pediatric PNE is based on previous findings in adult research that a better understanding of the nature of the illness results in improved patient outcomes. When children do not understand the origin of their pain, they might develop irrational beliefs and fears (including catastrophizing) about their pain, sustaining the vicious circle of chronic pain. Indeed, the information and context in which children perceive their pain, has been shown to modulate pain expectations and emotional response to pain. Since research findings showed that even parental beliefs about the aetiology of the child's pain influences the child's pain outcomes, the role of parents as 'pain modulators' might not be underestimated. Therefore, parents should be involved during PNE.

Before and subsequent to providing children and their parents with PNE, it might be interesting to assess their previous knowledge and the change in knowledge about the neurophysiology of pain. To date, this aspect can be evaluated in adults by using the Neurophysiology of Pain Questionnaire (NPQ), a questionnaire developed and published by Moseley et al.. This instrument assesses the patients' reconceptualization of pain, and is validated in English and in Dutch. The questionnaire consists of 19 items and was originally based on examination papers of postgraduate medicine students. Various studies have used the NPQ to evaluated pain-related knowledge in adult chronic pain populations, such as chronic low back pain, chronic fatigue syndrome and chronic whiplash associated disorder. Additionally, previous research suggested the use of the NPQ in a study protocol to evaluate the effectiveness of brief education in the prevention of chronic low-back pain in an at-risk population. Noteworthy, the NPQ is also commonly used in clinical practice as a guideline for clinicians during educational sessions about chronic musculoskeletal pain. Previous research has proven adequate clinimetric properties of the English and Dutch version. One study, using a Rash analysis to evaluate the clinimetric properties of the NPQ in an adult chronic spinal population, found the NPQ to have (1) an acceptable internal consistency to assess individuals, (2) to be effective in targeting the ability of a typical group of chronic pain patients, (3) to be a unidimensional scale and (4) to have good test-retest reliability. Examination of the Dutch version showed fair reliability when retesting occurred within 24 hours, acceptable test-retest reliability and one dimensionality of the questionnaire. To conclude, the NPQ has proven to be a reliable and valid measurement instrument for determining the understanding and knowledge of neurophysiology of pain in adult chronic pain populations and healthcare professionals.

Based on this evidence in adults, it may be valuable to develop and examine the clinimetric properties of a Dutch Pediatric Neurophysiology of Pain Questionnaire (PedNPQ) to determine pain knowledge gaps in children. ;
