Background/Objectives: Chronic pain symptoms can disrupt cognitive processes. Such interruptions may negatively impact one's overall functioning, causing frustration and distress when engaging in important tasks. This experience has been referred to as cognitive intrusion of pain. To date, only one adult self-report measure of cognitive intrusion of pain exists: the Experience of Cognitive Intrusion of Pain (ECIP). The purpose of the current study was to examine the psychometric properties of the ECIP in a sample of pediatric patients with chronic pain. Methods: The internal consistency reliability, factor structure, and validity of the ECIP were evaluated in a sample (N = 182) of youth ages 11 to 18 who presented to a multidisciplinary chronic pain clinic at a large Midwestern children's hospital in the United States. Results: Results suggest excellent reliability (α = 0.94). Confirmatory factor analysis results supported a one-factor model, with excellent model fit. The ECIP demonstrated evidence of convergent validity, with moderate and positive correlations with measures of pain-related limitations in functioning, pain symptoms, anxiety, and depression. Regarding discriminant validity evidence, the ECIP was minimally and inversely related to measures of readiness to transition to self-managed care and global health. Conclusions: Overall, the ECIP demonstrated strong initial reliability and validity evidence for use in pediatric chronic pain. Further research is recommended in more diverse samples and to evaluate the clinical utility of the ECIP.
