ABSTRACT
OBJECTIVE: Research indicates that perceived injustice significantly influences pain-related outcomes and is associated with delayed recovery in adults. This systematic review examines the relationship between perceived injustice and pain-related outcomes in children with pain conditions. METHODS: A search of published studies in English in PubMed, PsychInfo and Cochrane Database of Systematic Reviews from database inception through December 2022 was performed. The search criteria focused on studies that measured perceived injustice and pain-related outcomes in children with pain conditions. Out of 56 articles screened, 8 met the inclusion criteria, providing data on 1240 children with pain conditions. RESULTS: The average age of participants across all studies was 14.12 years (SD = 2.25), with 68.2% being female. There was strong evidence that higher perceived injustice is associated with worse pain intensity, functional disability, mental health outcomes, and emotional, social and school functioning. CONCLUSION: The results of this study underscore how perceptions of injustice are associated various pain-related outcomes across different domains of children's lives. The findings highlight the need for screening and treatments targeting injustice appraisals in pediatric populations with pain conditions. The discussion addresses possible determinants and mechanisms of perceived injustice, along with implications for research and clinical practice.
