After a rigorous process to generate items, assess content validity, evaluate readability and understandability, and pre-test items, a cohort of 124 children (aged 8-12▒y) independently completed the measure on two occasions, along with additional measures of pain, function, and pain-related distress.
The resulting unidimensional 14-item Concept of Pain Inventory (COPI) had acceptable internal consistency (α= 0.78) and moderate test-retest reliability (ICC (3,1) = 0.55 (95% CI 0.37 to 0.68)). Higher COPI scores reflect greater alignment with contemporary pain science. COPI scores were inversely correlated with pain intensity and functional disability, but unrelated to pain catastrophizing and pain-related fear. At 1-2 months follow-up, baseline COPI scores were inversely correlated with clinical variables of functional disability and pain intensity.
These results support the COPI as a brief, psychometrically sound tool to assess a child’s concept of pain. Clinically, this tool may facilitate individualized pain science education to target identified conceptual ‘gaps’ or misconceptions, as well as to evaluate the effectiveness of pain science education in children. Further research examining its efficacy and impact is warranted.
