采用逐步回归、因子分析和条目标度原则，从荷兰大样本(n=5,211)和喘息性疾病样本(n=138)中得出并指导条目选择。使用普通荷兰样本(Salland Region n=410)和两个临床样本：功能性腹痛(FAP，n=81)和烧伤(n=194)，评估条目的内部一致性、区分效度和地板和天花板效应。使用Cronbach‘s Alpha估计可靠性。相对精确度(RP)，即区分临床亚组的能力，通过比较短形式量表和相应的全量表解释的差异比例来计算。ITQOL从97个条目减少到47个条目。α系数的中位数分别为0.77、0.76(FAP)和0.84(烧伤)。在24个测验(8个量表，3个样本)中，有21个测验(8个量表，3个样本)的条目判别效度被观察到91-100%的测量成功率。没有观察到地板效应；检测到了一些天花板效应。Salland样本中的RP估计值从2.40(身体能力)到0.58(气质和情绪)。在FAP样本中的RP估计为0.85(身体疼痛)，1.36(气质和情绪)和1.62(父母影响情绪)，烧伤，1.51(气质和情绪)和0.59(一般健康认知)。ITQOL-SF47是可靠和有效的，并超过了项目级测量标准。
To derive and evaluate a shorter infant/toddler quality of life questionnaire (ITQOL) for use in clinical care.Stepwise regression, factor analysis, and item-scaling principles were used to derive and guide item selection using data from a large general sample in the Netherlands (n = 5,211) and a "wheezing illness" sample (n = 138). Item internal consistency, discriminant validity, and floor and ceiling effects were evaluated using a general Dutch sample (Salland Region n = 410) and two clinical samples: Functional abdominal pain (FAP, n = 81) and Burn (n = 194). Reliabilities were estimated using Cronbach's alpha. Relative precision (RP), the ability to distinguish between clinical subgroups, was computed by comparing the proportion of variance explained by the short-form scales versus respective full-length scales.The ITQOL was reduced from 97 to 47 items. Median alpha coefficients were 0.77 Salland sample, 0.76 (FAP), and 0.84 (Burn). Ninety-one to 100 % scaling successes for item discriminant validity were observed for 21 of 24 tests (8 scales, 3 samples). Floor effects were not observed; some ceiling effects were detected. RP estimates in the Salland sample ranged from 2.40 (physical abilities) to 0.58 (temperament and moods). RP estimates in the FAP sample were 0.85 (bodily pain), 1.36 (temperament and moods) and 1.62 (parental-impact emotional) and for Burn, 1.51 (temperament and moods) and 0.59 (general health perceptions).The ITQOL-SF47 is reliable and valid and exceeds item-level scaling criteria.
