项目反应理论（IRT）广泛用于开发与健康相关的生活质量（HRQOL）的自适应工具。但是，每个IRT模型都有自己的功能来估计项目和类别参数，因此，使用具有不同IRT模型的相同响应类别可以找到不同的结果。本研究使用Rasch评级量表模型（RSM）来检查和重新评估PEDSQLTM 4.0通用核心尺度的波斯版本的心理计量学特性。
PEDSQLTM 4.0通用核心尺度由938名伊朗学童及其父母完成。通过经典测试理论（CTT）评估了仪器的融合，判别和构造有效性。 RSM用于调查人员和项目的可靠性，项目统计信息以及响应类别的顺序。
CTT方法表明，除了儿童自我报告的身体健康外，在所有领域的收敛和判别有效性的缩放成功率均为100％。此外，验证性因素分析支持与其原始版本相似的四因素模型。 RSM显示23个项目中有22个具有可接受的INFIT和服装统计数据（<1.4，> 0.6），人的可靠性很低，项目可靠性很高，并且项目难度范围为-1.01至0.71至0.71至-0.68至0.43 - 报告和父母代理报告。 RSM还表明，所有项目的连续响应类别都不是预期的。
这项研究表明，在所有领域中，五个响应类别均未充分执行。尚不清楚这个问题是波斯语中响应选择的含义的函数还是大多数不使用响应类别范围的大多数健康人群的伪像。应在进一步的验证研究中评估反应类别，尤其是在慢性病患者的大量样本中。
Item response theory (IRT) is extensively used to develop adaptive instruments of health-related quality of life (HRQoL). However, each IRT model has its own function to estimate item and category parameters, and hence different results may be found using the same response categories with different IRT models. The present study used the Rasch rating scale model (RSM) to examine and reassess the psychometric properties of the Persian version of the PedsQLTM 4.0 Generic Core Scales. The PedsQLTM 4.0 Generic Core Scales was completed by 938 Iranian school children and their parents. Convergent, discriminant and construct validity of the instrument were assessed by classical test theory (CTT). The RSM was applied to investigate person and item reliability, item statistics and ordering of response categories. The CTT method showed that the scaling success rate for convergent and discriminant validity were 100% in all domains with the exception of physical health in the child self-report. Moreover, confirmatory factor analysis supported a four-factor model similar to its original version. The RSM showed that 22 out of 23 items had acceptable infit and outfit statistics (<1.4, >0.6), person reliabilities were low, item reliabilities were high, and item difficulty ranged from -1.01 to 0.71 and -0.68 to 0.43 for child self-report and parent proxy-report, respectively. Also the RSM showed that successive response categories for all items were not located in the expected order. This study revealed that, in all domains, the five response categories did not perform adequately. It is not known whether this problem is a function of the meaning of the response choices in the Persian language or an artifact of a mostly healthy population that did not use the full range of the response categories. The response categories should be evaluated in further validation studies, especially in large samples of chronically ill patients.
