• Sleep quality partially mediated the association between post-traumatic stress symptoms (PTSS) and pain characteristics among a cohort of youth with chronic pain.• Higher PTSS was associated with higher levels of both pain intensity and pain interference and these PTSS-pain relationships were partially explained by poor sleep quality.• Findings provide empirical support for the pediatric model of mutual maintenance in PTSS and chronic pain, which posits that sleep disturbance is a key intrapersonal factor driving this co-occurrence.
