Health-related quality of life (HRQL) is perceived as an important health-care outcome. There are several systems for measuring the HRQL in adults but there are few such systems for children in Japan. Pediatric Quality of Life Inventory (PedsQL) is valid and demonstrates excellent reliability in the USA, Europe, and Asian countries. The aim of the present study was therefore to develop the Japanese version of PedsQL.
A two-step procedure was performed: translation of PedsQL, followed by examination of the psychometric properties in a cross-sectional study. The feasibility, reproducibility, internal consistency reliability, factor structure, and concurrent and clinical validity were examined.
The internal consistency reliability of the Child Self-Reports of young children was slightly low, but that of the Child Self-Reports of school children and adolescents was good. Further, all the Parent Proxy-Reports had excellent alphas. The Japanese version had satisfactory feasibility for all age ranges. The intercorrelation of subscales supported the multidimensional factor structure. Clinical validity was examined by analysis of variance performed for four groups with different health conditions (healthy, chronic needs only, mental condition only, and chronic needs and mental condition). The scores of each functioning scale differed among the four groups, with the healthy group having the highest scores for all functioning scales.
The Japanese version of PedsQL can be applied in community and school health settings in Japan. Because children with chronic health needs and mental conditions were included, the Japanese version of PedsQL is expected to be useful in clinical settings.
健康相关生活质量（HRQL）被视为一项重要的医疗保健成果。有多种用于测量成人HRQL的系统，但在日本，针对儿童的此类系统却很少。儿童生活质量量表（PedsQL）在美国、欧洲和亚洲国家均有效且具有出色的可靠性。因此，本研究的目的是开发PedsQL的日语版本。
采用了两步法：首先翻译PedsQL，然后在横断面研究中检验其心理测量特性。检验了可行性、可重复性、内部一致性信度、因子结构以及同时效度和临床效度。
幼儿的儿童自我报告的内部一致性信度略低，但学龄儿童和青少年的儿童自我报告的内部一致性信度良好。此外，所有家长代理报告的阿尔法系数都很高。日语版本在所有年龄范围都具有令人满意的可行性。分量表之间的相互关联支持多维因子结构。通过对具有不同健康状况的四组（健康、仅患有慢性疾病、仅患有精神疾病以及患有慢性疾病和精神疾病）进行方差分析来检验临床效度。四个组中每个功能量表的得分有所不同，健康组在所有功能量表上得分最高。
PedsQL的日语版本可应用于日本的社区和学校健康环境。由于纳入了患有慢性健康需求和精神疾病的儿童，预计PedsQL的日语版本在临床环境中会很有用。
