Comparisons of QOL Measures
Table 3 shows small to medium effect sizes for the relationships between the three QOL measures. For the parent PedsQL, posture was only correlated with the subscales of pain and nausea. In contrast, the child PedsQL was correlated with the total score, nausea, treatment anxiety, and cognitive scales. On the parent PedsQL, the Faces Scale was correlated with the total score, pain, worry, and appearance. For the child PedsQL, the Faces Scale was also correlated with the total score, pain, and cognitive scales. Posture and the Faces Scale were positively correlated.
