Parker DM, et al. - Researchers examined how caregiver and child influence partner catastrophizing about child pain over a period of 1 month following initiation of interdisciplinary pain treatment. Further, they determined if the change in pain catastrophizing was correlated with child pain interference. Among a total of 113 caregiver-child dyads (M_age = 14.41), caregivers and children independently summarized on catastrophizing about child pain and child pain interference at baseline and 1-month follow-up. A reduction in caregiver and child pain catastrophizing was observed over 1 month after initial interdisciplinary pain evaluation, which was associated with increased child function. The average scores remained in the moderate to high range. Findings highlight that child cognitive-affective responses to pain play important role in regulating caregiver catastrophizing about child pain. They suggest understanding the individual contributions children and caregivers make to interpersonal pain processes as valuable for informing future family-level clinical interventions.
