OBJECTIVE
To conduct a multimethod psychometric evaluation to refine the Children's Somatization Inventory (CSI) and to investigate its dimensionality.
METHOD
The CSI was administered to 876 pediatric patients with chronic abdominal pain at their initial visit to a pediatric gastroenterology clinic. Tools from three psychometric models identified items that most effectively measured the construct of somatization and examined its dimensionality.
RESULTS
Eleven statistically weak items were identified and removed, creating a 24-item CSI (CSI-24). The CSI-24 showed good psychometrics according to the three measurement models and correlated .99 with the original CSI. The CSI-24 has one dominant general factor but is not strictly unidimensional.
CONCLUSIONS
The CSI-24 is a reliable and psychometrically sound refinement of the original CSI. Findings are consistent with the view that somatization has a strong general factor that represents a continuum of symptom reporting, as well as minor components that represent specific symptom clusters in youth with chronic abdominal pain.
目的
进行多方法心理测量评估，以完善儿童躯体化量表（CSI）并研究其维度。
方法
在876名因慢性腹痛首次就诊于儿科胃肠病诊所的儿科患者中施测CSI。来自三种心理测量模型的工具识别出最能有效测量躯体化结构的项目，并检查其维度。
结果
识别并删除了11个统计学上较弱的项目，形成了一个24项的CSI（CSI - 24）。根据三种测量模型，CSI - 24显示出良好的心理测量学特性，与原始CSI的相关性为0.99。CSI - 24有一个占主导地位的一般因素，但并非严格单维。
结论
CSI - 24是对原始CSI的可靠且心理测量学上合理的完善。研究结果与以下观点一致，即躯体化有一个强大的一般因素，代表症状报告的连续体，以及一些次要成分，代表患有慢性腹痛的青少年中的特定症状群。
