['Examine whether the relation between protective parenting responses to pain and functional disability is mediated by pain catastrophizing in adolescents with chronic musculoskeletal pain and their parents over time.', 'Adolescents aged 11-18 years and their parents reported on parental protective responses to pain (PPRP), pain catastrophizing scale (PCS), and Functional Disability Inventory (FDI) before Time 1 (T1) and 2 months after Time 2 (T2) an initial interdisciplinary pain clinic evaluation.', 'PCS was a significant mediator of the PPRP-FDI relationship at T1 and T2 for the adolescents and T2 for their parents. A decrease in PPRP over time was associated with T2 PCS, which in turn was associated with T2 FDI for adolescents and their parents.'] Does adolescent pain catastrophizing mediate the relationship between protective parental responses to pain and disability over time?
