背景资料。PedsQL(儿童生活质量调查)(加州圣地亚哥儿童医院和健康中心)是一种测量2至8岁儿童和青少年健康相关生活质量(HRQOL)的模块化工具。PedsQL 4.0通用核心量表是多维儿童自我报告和父母代理报告量表，作为通用护理措施开发，与精细的PedsQL疾病特定模块集成。PedsQL 4.0通用核心量表由23个条目组成，适用于健康的学校和社区人群，以及有急慢性疾病的儿童人群。方法：对963名儿童和1,629名家长(总计1,677名受试者)进行了4个PedsQL 4.0通用核心问卷(生理、情绪、社会、学校)的测试。结果：量表总分(阿尔法=0.88名儿童，0.90名家长报告)、身体健康总分(阿尔法=0.80名儿童，0.88名家长)和心理社会健康总分(阿尔法=0.83名儿童，0.86名家长)的一致性信度可接受。使用已知分组方法、与发病率和疾病负担指标的相关性以及因子分析来验证有效性。PedsQL量表区分健康儿童和急慢性疾病儿童，与发病率和疾病负担指标相关，与先验概念派生量表基本一致。结论PedsQL 4.0全科护理量表具有较好的信度和效度。PedsQL 4.0通用核心量表可能适用于临床试验、研究、临床实践、学校卫生机构和社区人群。
BACKGROUND. The PedsQL (Pediatric Qualify of Life Inventory) (Children's Hospital and Health Center, San Diego, California) is a modular instrument for measuring health-related quality of life (HRQOL) in children and adolescents ages 2 to I8. The PedsQL 4.0 Generic Core Scales are multidimensional child self-report and parent proxy-report scales developed as the generic care measure to be integrated with fine PedsQL Disease-Specific Modules. The PedsQL 4.0 Generic Core Scales consist of 23 items applicable for healthy school and community populations, as well as pediatric populations with acute and chronic health conditions.METHODS. The 4 PedsQL 4.0 Generic Core Scales (Physical, Emotional, Social, School) were administered to 963 children and 1,629 parents (1,677 subjects accrued overall) recruited from pediatric health care settings. Item-level and scale-Level measurement properties were computed.RESULTS. Infernal consistency reliability for the Total Scale Score (alpha = 0.88 child, 0.90 parent report), Physical Health Summary Score (alpha = 0.80 child, 0.88 parent), and Psychosocial Health Summary Score (alpha = 0.83 child, 0.86 parent) were acceptable for group comparisons. Validity was demonstrated using the known-groups method, correlations with indicators of morbidity and illness burden, and factor analysis. The PedsQL distinguished between healthy children and pediatric patients with acute or chronic health conditions, was related to indicators of morbidity and illness burden, and displayed a factor-derived solution largely consistent with the a priori conceptually-derived scales.CONCLUSION. The results demonstrate the reliabiity and validity of the PedsQL 4.0 Generic Care Scales. The PedsQL 4.0 Generic Core Scales may be applicable in clinical trials, research, clinical practice, school health settings, and community populations.
