This study focuses on adapting the Graded Chronic Pain Scale-Revised for use with pediatric samples (P-GCPS-R) and assessing its concurrent validity. The P-GCPS-R was completed by 1,564 students aged 8-18 years old, along with measures of physical health, anxiety and depressive symptoms, maladaptive pain coping strategies, and activity limitations. The results show that 14% of participants reported experiencing chronic pain, with 5% having mild chronic pain, 6% bothersome chronic pain, and 3% high-impact chronic pain. Participants with bothersome and high-impact chronic pain reported worse physical health, more anxiety and depressive symptoms, pain catastrophizing, and activity limitations compared to those with mild chronic pain. The study findings suggest that the P-GCPS-R has concurrent validity for use with pediatric samples, and could be useful for assessing the severity of chronic pain in children and adolescents.
