PedsQL 3.0 Cancer Module
The PedsQL 3.0 Cancer Module evolved from the PedsQL 4.0 Generic Core Scale.32 The instrument employs a Parent-Proxy Report for ages 2-18 years and a companion Child Self-Report for children aged 5 years and older. The scores range from 0 to 100 with a larger score indicating better QOL. Validity and reliability testing for both the Core Scale and Cancer Module have been extensive. The Cancer Module is a 27-item instrument that includes 8 subscales (pain and hurt, nausea, procedural anxiety, treatment anxiety, worry, cognitive problems, perceived physical appearance, and communication). The instruments have been successfully employed in several studies of children with cancer.33-35 The PedsQL has been shown to be the most responsive to change when compared with other measures of QOL for children undergoing chemotherapy.36,37
