Pediatric somatization studies have used the 35-item Child Somatization Inventory (CSI-35) or psychometrically refined 24-item CSI (CSI-24). Exploratory factor analysis of the CSI-24 has identified a single factor that did not show good model fit in confirmatory factor analysis (CFA). Further evaluation of the CSI-24 factor structure is needed.
The present study examined alternative factor structures of the CSI-24 in a community sample (N = 233, ages 8-15).
The CFA showed good fit for a single CSI-24 factor, better fit for multiple factor models, and best fit for a single, six-item factor. Construct validity for that factor was found in significant correlations with anxiety, depression, functional disability, and quality of life.
Results are consistent with a single somatization factor, but research is needed to verify the factor structure in different, race/ethnic/demographic, and clinical groups.
儿科躯体化研究使用了 35 项儿童躯体化量表(CSI-35)或经过心理测量学修正的 24 项 CSI(CSI-24)。CSI-24 的探索性因素分析确定了一个单一因素,在验证性因素分析(CFA)中没有表现出良好的模型拟合。需要进一步评估 CSI-24 的因子结构。
本研究在社区样本(N=233,年龄 8-15 岁)中检验了 CSI-24 的替代因子结构。
CFA 显示单一 CSI-24 因子具有良好的拟合度,多因子模型拟合度更好,而单一的六因子模型拟合度最佳。该因子与焦虑、抑郁、功能障碍和生活质量存在显著相关性,表明其具有良好的结构效度。
结果与单一躯体化因子一致,但需要在不同的种族/民族/人口统计学和临床群体中验证该因子结构。
