1. Differential Utility of Pain Catastrophizing by Reporter for Predicting Later Functioning in Chronic Pain Susan T. Tran 1, Gustavo R. Medrano 1, Kim Anderson Khan 2, Renee J. Ladwig 3, Steven J. Weisman 2, W. Hobart Davies 1, & Keri R. Hainsworth 2 1 University of Wisconsin-Milwaukee, 2 Medical College of Wisconsin, 3 Children’s Hospital of Wisconsin Mothers’ Pain Catastrophizing Mothers’ increased PC at intake, and at 1 month predicted their decreased HRQOL at 1 and 3 months, respectively, above pain characteristics (ΔR 2 =.19 and ΔR 2 =.45, both p <.01). Mothers’ PC did not predict children’s HRQOL at either time point (ΔR 2 =.04 and ΔR 2 =.07, both p = ns). Youths’ Pain Catastrophizing Youths’ increased PC at intake and at 1 month predicted their decreased HRQOL at 1 and 3 months, respectively, above pain characteristics (ΔR 2 =.14, p <.01 and ΔR 2 =.24, p <.05). Youths’ PC did not predict mothers’ HRQOL at either time point (ΔR 2 =.04 and ΔR 2 =.03, both p = ns). Mothers’ and youths’ PC significantly predict their own later HRQOL, but not each others’. This is contrary to past research which has shown an interaction between child and parent functioning, including the longitudinal relationship between parent HRQOL and child HRQOL. Future research should clarify how family variables and context influence treatment outcomes for both patients and parents. Given the importance of PC, results highlight the need for family involvement in treatment to reduce maladaptive perceptions of pain in order to improve parents’ and children’s HRQOL. Participants Eighty-two mother-youth dyads 76% female youth, 84% Caucasian 8-18 years (M = 14.45, SD = 2.58) Procedure Youth and their parents completed questionnaires while receiving care at an interdisciplinary chronic pain clinic. Timepoints: Intake, 1, and 3 months Measures Pain Catastrophizing Scale – child and parent PedsQL – child HRQOL Family Impact Module – parent HRQOL Data analysis Stepwise regression analyses: Pain characteristics entered in first step (duration, usual intensity, and frequency) Pain catastrophizing entered in second step Pain Characteristics Duration of pain M = 21.72 months, SD = 23.05 Usual pain M = 6.30, SD = 2.00 Pain frequency M = 11.54 days out of last 14 days, SD = 3.65 For more information, please contact Susan Tran at stheinze@uwm.edu. Presented at the 2013 National Conference for Pediatric Psychology Pain catastrophizing (PC) is an important predictor of decreased health related quality of life (HRQOL) in youth with chronic pain (Libby & Glenwick, 2010). Parental beliefs regarding children's chronic pain affect children's ability to cope (Simons et al., 2008; Crushell et al., 2003; Logan & Scharff, 2005). However, parent variables have frequently been excluded from studies (Palermo & Eccleston, 2009). There are few longitudinal studies including parent variables.
