Objectives: The aims of this study were: (1) investigate relations between pain acceptance, depressive symptoms, catastrophizing, and functional disability in pediatric patients in an interdisciplinary chronic pain rehabilitation program, (2) examine changes in acceptance from pre- to posttreatment, and (3) test if changes in acceptance predict changes in depressive symptoms, catastrophizing, and functional disability from pre- to posttreatment.
Methods: 112 participants, ages 11-18 years, completed the Chronic Pain Acceptance Questionnaire, Adolescent Version, Center for Epidemiological Studies-Depression-Children's Scale, Pain Catastrophizing Scale for Children, and Functional Disability Inventory on admission to and completion of the program.
Results: Significant and strong relations between acceptance, depression, catastrophizing, and functional disability were demonstrated. Participants demonstrated significant increases in acceptance and decreases in depression, catastrophizing, and functional disability. Finally, changes in acceptance significantly predicted changes in depressive symptoms, catastrophizing, and functional disability.
Conclusions: Pain acceptance is an important variable in the treatment of pediatric chronic pain.
