目的。目的探讨儿童生活质量问卷(PedsQL 4.0)在评估屈光不正对新加坡学龄前儿童健康相关生活质量(HRQL)影响中的心理测量学效度。学步儿童(25至48个月)和幼儿(49至72个月)的父母完成了PedsQL 4.0，这是新加坡基于人群的试验的一部分。结果测量是总分，以及“身体”、“情感”、“社交”和“学校”功能子量表。采用Rasch分析对PedsQL4.0进行验证。939名(48.9%)幼儿和982名(51.1%)幼儿的父母完成了PedsQL4.0调查。幼儿右眼总体平均(+/-)球面等效度为0.47+/-1.13 D，幼儿为0.74+/-1.22 D。149名幼儿(15.9%)和90名幼儿(9.2%)被认为近视(-0.50D)。大多数受试者(n=1286，89.6%)的视力达到或超过6/9。Rasch分析显示，这两组人的类别阈值和不良的人-物目标都有混乱的证据。幼儿的分离可靠性为0.00，幼儿的分离可靠性为0.03，表明两个样本之间没有差异。PedsQL 4.0总分和分量表得分显示出显著的多维性，因为测量解释的方差值是
Purpose. To determine the psychometric validity of the pediatric quality of life inventory (PedsQL 4.0) in assessing the impact of refractive errors on health-related quality of life (HRQoL) in preschool children in Singapore.Methods. Parents of toddlers (aged 25 to 48 months) and young children (49 to 72 months) completed the PedsQL 4.0, an HRQoL scale as part of population-based trial in Singapore. The outcome measures were the overall score, and the "physical"; "emotional"; "social"; and "school" functioning subscales. Rasch analysis was used to validate the PedsQL 4.0.Results. Parents of 939 (48.9%) toddlers and 982 (51.1%) young children completed the PedsQL 4.0 survey. The overall mean (+/-standard deviation) spherical equivalence for the right eye was 0.47 +/- 1.13 diopter (D) for toddlers and 0.74 +/- 1.22 D for young children. One hundred forty-nine (15.9%) toddlers and 90 (9.2%) young children were considered myopic (>=-0.50 D). Most participants (n = 1286, 89.6%) had presenting visual acuity 6/9 or better. Rasch analysis showed evidence of disordered category thresholds and poor person-item targeting for both groups. The separation reliability was 0.00 for toddlers and 0.03 for young children, indicating there was no variance in both samples. The PedsQL 4.0 overall and subscale scores displayed substantial multidimensionality as the variance values explained by the measures was
