Baseline Factors Associated with Pain Intensity, Pain Catastrophizing, and Pain Interference in Intensive Interdisciplinary Pain Treatment for Youth

Background: More could be known about baseline factors related to desirable Intensive Interdisciplinary Pain Treatment (IIPT) outcomes. This study examined how characteristics (age, gender, child pain catastrophizing (PCS-C), interference, intensity, anxiety, depression, paediatric health-related quality of life (PedsQLTM), and parent (PCS-P)) were associated with discharge 3-month follow-up scores PCS-C, interference. Methods: interference T-scores acquired in 45 IIPT patients aged 12–18 at intake (baseline), discharge, follow-up. Using available imputed data, linear mixed models developed explore associations between aggregated demographics a priori selected measures pain, PCS-C/P. Results: PCS-C decreased over time compared baseline. intensity did not change significantly. Baseline PedsQLTM discharge/follow-up (available data) data). Only was significantly itself discharge/follow-up. Conclusions: Participants who completed the program presented reduced time. Interventions that target pre-treatment anxiety depression may optimize
