Stress Numerical Rating Scale-11: Validation in Pediatric Inpatient and Outpatient Pain Settings.

Stress is a commonly reported issue in pediatric populations of chronic and acute pain. Both outpatient and inpatient settings impose time constraints, which decreases opportunities to measure and address patient stress. The aim of these studies was to evaluate the validity of the Stress Numeric Rating Scale-11 (SNRS-11) in both inpatient and outpatient settings.
