The total scale score (23 items) consists of Physical health summary score (8 items) and Psychosocial health summary score (15 items). Physical health summary includes Physical Functioning (8 items) and Psychosocial health summary score includes Emotional Functioning (5 items), Social Functioning (5 items) and School Functioning (5 items). The overall range for PedsQL scores is 0 to 100, with a higher score indicating better quality of life.
