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. The SNRS-11 is a single item stress measure ranging from 0 to 10 with endpoint anchors: 0 = "No stress" and 10 = "Highest stress possible". Results showed discriminative validity in the inpatient sample and convergent and discriminant validity in both outpatient and inpatient samples. Additionally, approximately 40% to 50% of the sample reported moderate-severe stress on all post-operative days. The SNRS-11 shows promise as a quick, easy, and free stress measure to be used in both inpatient and outpatient settings.
