Stone AL, et al. - For the transmission of risk of chronic pain (CP) from parents to offspring, social learning, such as parental modeling and reinforcement, represented one plausible mechanism. In this work, a model was tested in which parental CP predicted adolescents' daily average CP severity and functional impairment (distal outcomes) via parental modeling of pain behaviors and parental reinforcement of adolescent's pain behaviors (mediators) and adolescents' cognitive appraisals of pain threat (proximal outcome representing adolescents' encoding of parents' behaviors) based on a 7-day pain diary in pediatric patients with functional abdominal CP. Findings suggest that for family-based interventions, parental modeling of pain behaviors represents a potentially promising target to ameliorate pediatric CP.
