Objective: 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.
Methods: 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.
Results: 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.
Conclusion: Parental protectiveness is associated with disability indirectly through pain catastrophizing at the initial visit and follow-up. Decreases in parent protectiveness, potentially initiated through the initial evaluation, were related to lower levels of disability at follow-up through pain catastrophizing.
