  1. Legend. PedsQL SF-15 = pediatric quality of life inventory short form 15 item. HRQoL = health-related quality of life. PedsQL SF-15 scores range from 0 to 100 with higher scores indicating better HRQoL. Intra-class correlations (ICCs) were rated as 0–0.40: poor agreement; 0.41–0.60: moderate agreement; 0.61–0.80: good agreement; and 0.81–1.00 excellent agreement. The Psychosocial Health Summary Score is the sum of the items over the number of items answered in the Emotional, Social, and School Functioning Scales. The Physical Health Summary score is equal to the Physical Functioning Scale Score. The Total Summary Score is the sum of all items over the number of items answered on all of the scales
