The aim of this study was to examine the psychometric properties of the Psychosocial Risk Assessment in Pediatrics (PRAP). PRAP is a screening tool designed to assess pediatric patients who are at risk of experiencing elevated distress during health-care encounters. A cross-sectional observational study was conducted with 200 pediatric patients. Patient’s distress levels were observed during their health-care encounter using the Children’s Emotional Manifestation Scale (CEMS). Health-care staff and parents were asked to rate the patient’s level of cooperation and stress. Exploratory factor analysis supported a single latent factor structure of the PRAP tool. Cronbach’s α for internal reliability was .83. PRAP score was strongly correlated with CEMS score with r = .82 (p < .0001). The PRAP is a standardized, reliable, and valid method for health-care providers to assess a patient’s risk of experiencing significant distress during treatment or testing.
