The PedsQL Measurement Model is a modular approach to measuring health-related quality of life (HRQOL) in healthy children and adolescents and those with acute and chronic health conditions. The PedsQL Measurement Model integrates seamlessly both generic core scales and disease-specific modules into one measurement system.

The PedsQL Generic Core Scales are:
Brief (23 items)
Practical (Less than 4 minutes to complete)
Flexible (Designed for use with community, school, and clinical pediatric populations).
Developmentally Appropriate (Ages 2-18; Child Self-Report Ages 5-7, 8-12, 13-18; Parent Proxy-Report Ages 2-4, 5-7, 8-12, 13-18).
Multidimensional (Physical, Emotional, Social, School Functioning).
Reliable (Total Scale Score: 0.88 Child Self-Report; 0.90 Parent Proxy-Report).
Valid (Distinguishes between healthy children and children with acute and chronic health conditions; distinguishes disease severity within a chronic health condition).
Responsive to clinical change over time.
Translated into multiple languages including broadcast Spanish.

The 23-item PedsQL Generic Core Scales were designed to measure the core dimensions of health as delineated by the World Health Organization, as well as role (school) functioning. The 4 Multidimensional Scales and 3 Summary Scores are:

Physical Functioning
(8 items)
Emotional Functioning
(5 items)
Social Functioning
(5 items)
School Functioning

Summary Scores
Total Scale Score
