BACKGROUNDThe Pediatric Quality of Life Inventory (PedsQL) is a modular instrument designed to measure health‐related quality of life (HRQOL) in children and adolescents ages 2–18 years. The PedsQL 4.0 Generic Core Scales are multidimensional child self‐report and parent proxy‐report scales developed as the generic core measure to be integrated with the PedsQL disease specific modules. The PedsQL Multidimensional Fatigue Scale was designed to measure fatigue in pediatric patients. The PedsQL 3.0 Cancer Module was designed to measure pediatric cancer specific HRQOL.METHODSThe PedsQL Generic Core Scales, Multidimensional Fatigue Scale, and Cancer Module were administered to 339 families (220 child self‐reports; 337 parent proxy‐reports).RESULTSInternal consistency reliability for the PedsQL Generic Core Total Scale Score (α = 0.88 child, 0.93 parent report), Multidimensional Fatigue Total Scale Score (α = 0.89 child, 0.92 parent report) and most Cancer Module Scales (average α = 0.72 child, 0.87 parent report) demonstrated reliability acceptable for group comparisons. Validity was demonstrated using the known‐groups method. The PedsQL distinguished between healthy children and children with cancer as a group, and among children on‐treatment versus off‐treatment. The validity of the PedsQL Multidimensional Fatigue Scale was further demonstrated through hypothesized intercorrelations with dimensions of generic and cancer specific HRQOL.CONCLUSIONSThe results demonstrate the reliability and validity of the PedsQL Generic Core Scales, Multidimensional Fatigue Scale, and Cancer Module in pediatric cancer. The PedsQL may be utilized as an outcome measure in clinical trials, research, and clinical practice. Cancer 2002;94:2090–106. © 2002 American Cancer Society.DOI 10.1002/cncr.10427

Background: The PedsQL™ Measurement Model was designed to measure health-related quality of life (HRQOL) in children and adolescents. The PedsQL™ 4.0 Generic Core Scales were developed to be integrated with the PedsQL™ Disease-Specific Modules. The newly developed PedsQL™ Family Impact Module was designed to measure the impact of pediatric chronic health conditions on parents and the family. The PedsQL™ Family Impact Module measures parent selfreported physical, emotional, social, and cognitive functioning, communication, and worry. The Module also measures parent-reported family daily activities and family relationships.

In preparation for the design, construction, and postoccupancy evaluation of a new Children's Convalescent Hospital, focus groups were conducted and measurement instruments were developed to quantify and characterize parent and staff satisfaction with the built environment of the existing pediatric health care facility, a 30-year-old, 59-bed, long-term, skilled nursing facility dedicated to the care of medically fragile children with complex chronic conditions. The measurement instruments were designed in close collaboration with parents, staff, and senior management involved with the existing and planned facility. The objectives of the study were to develop pediatric measurement instruments that measured the following: (1) parent and staff satisfaction with the built environment of the existing pediatric health care facility, (2) parent satisfaction with the health care services provided to their child, and (3) staff satisfaction with their coworker relationships. The newly developed Pediatric Quality of Life Inventory scales demonstrated internal consistency reliability (average alpha = 0.92 parent report, 0.93 staff report) and initial construct validity. As anticipated, parents and staff were not satisfied with the existing facility, providing detailed qualitative and quantitative data input to the design of the planned facility and a baseline for postoccupancy evaluation of the new facility. Consistent with the a priori hypotheses, higher parent satisfaction with the built environment structure and aesthetics was associated with higher parent satisfaction with health care services (r =.54, p <.01; r =.59, p <.01, respectively). Higher staff satisfaction with the built environment structure and aesthetics was associated with higher coworker relationship satisfaction (r =.53; p <.001; r =.51; p <.01, respectively). The implications of the findings for the architectural design and evaluation of pediatric health care facilities are discussed.
