The PedsQL (Pediatric Quality of Life Inventory) is a modular instrument designed to measure health-related quality of life (HRQOL) and disease-specific symptoms in children and adolescents. The PedsQL Multidimensional Fatigue Scale was designed as a child self-report and parent proxy-report generic symptom-specific instrument to measure fatigue in pediatric patients. The objective of the present study was to determine the feasibility, reliability, and validity of the PedsQL Multidimensional Fatigue Scale in pediatric obesity.
The 18-item PedsQL Multidimensional Fatigue Scale (General Fatigue, Sleep/Rest Fatigue, and Cognitive Fatigue domains) and the PedsQL 4.0 Generic Core Scales were completed by 41 pediatric patients with a physician-diagnosis of obesity and 43 parents from a hospital-based Pediatric Endocrinology Clinic.
The PedsQL Multidimensional Fatigue Scale evidenced minimal missing responses (1.6%, child report; 0.5%, parent report), achieved excellent reliability for the Total Fatigue Scale Score (alpha = 0.90 child report, 0.90 parent report), distinguished between pediatric patients with obesity and healthy children, and was significantly correlated with the PedsQL 4.0 Generic Core Scales supporting construct validity. Pediatric patients with obesity experienced fatigue comparable with pediatric patients receiving cancer treatment, demonstrating the relative severity of their fatigue symptoms.
The results demonstrate the measurement properties of the PedsQL Multidimensional Fatigue Scale in pediatric obesity. The findings suggest that the PedsQL Multidimensional Fatigue Scale may be utilized in the standardized evaluation of fatigue in pediatric patients with obesity.
儿童生活质量量表（PedsQL，Pediatric Quality of Life Inventory）是一种模块化工具，旨在测量儿童和青少年与健康相关的生活质量（HRQOL）及特定疾病症状。PedsQL多维疲劳量表被设计为一种儿童自评和家长代理报告的通用症状特异性工具，用于测量儿科患者的疲劳情况。本研究的目的是确定PedsQL多维疲劳量表在儿童肥胖症中的可行性、可靠性和有效性。
41名经医生诊断为肥胖症的儿科患者和43名来自一家医院儿科内分泌诊所的家长完成了包含18个条目的PedsQL多维疲劳量表（一般疲劳、睡眠/休息疲劳和认知疲劳领域）以及PedsQL 4.0通用核心量表。
PedsQL多维疲劳量表显示缺失回答极少（儿童报告为1.6%；家长报告为0.5%），总疲劳量表得分具有出色的可靠性（儿童报告的α系数 = 0.90，家长报告的α系数 = 0.90），能区分肥胖儿科患者和健康儿童，并且与支持结构效度的PedsQL 4.0通用核心量表显著相关。肥胖儿科患者经历的疲劳程度与接受癌症治疗的儿科患者相当，表明其疲劳症状的相对严重性。
结果证明了PedsQL多维疲劳量表在儿童肥胖症中的测量特性。研究结果表明，PedsQL多维疲劳量表可用于对肥胖儿科患者疲劳情况的标准化评估。
