Examining tools for assessing the impact of chronic pain on emotional functioning in children and young people with cerebral palsy: stakeholder preference and recommendations for modification.

Purpose: To firstly identify tools for assessing the impact of chronic pain on emotional functioning in children and young people with cerebral palsy (CP), and secondly identify suggestions to improve their relevance, comprehensiveness, comprehensibility and feasibility for the CP population. Improving assessment of the impact of pain on emotional functioning can enhance quality of life by improving access to interventions for pain-related physical disability, anxiety and depression.

Methods: Ethics approval was granted through the Women's and Children's Health Network Human Research Ethics Committee (2022/HRE00154). A mixed methods study with people with lived experience and clinicians, and guided by the Consensus-based Standards for Measurement Instruments (COSMIN), was undertaken. An online survey identified the highest rated tools for validation and/or modification for young people with CP and chronic pain. Focus groups and interviews investigated content validity and feasibility of the tools identified as highest rated.

Results: The Fear of Pain Questionnaire for Children-SF (FOPQ-C-SF) and Modified Brief Pain Inventory (mBPI) were the highest rated for pain coping and multidimensional assessment (respectively) from the online survey (n = 61) of eight tools presented. Focus group and interview data (n = 30), including 58 unique modification suggestions, were coded to six categories: accessibility, comprehensibility, feasibility, relevance, presentation and comprehensiveness.

Conclusion: Potential modifications have been identified to improve the appropriateness and feasibility of the FOPQ-C-SF and mBPI for children and young people with CP. Future research should implement and test these modifications, prioritising the involvement of people with lived experience to ensure their needs are met alongside clinicians.
