The Children's Somatization Inventory (CSI) has proved to be a suitable measure to assess somatic symptoms in pediatric patients, but additional research was needed to evaluate its psychometric properties in community populations.
The objective of the present study was to examine psychometric properties and factorial structure of the instrument among a nonclinical sample of Spanish children.
The 24-item version of the CSI and two self-report measures of anxiety and depression were administered to 1,111 Spanish children aged 8 to 12.
Exploratory analysis suggested a factorial structure composed of three factors: pseudoneurologic symptoms, gastrointestinal symptoms, and pain. Due to confirmatory analysis indicating a poor fit for the three-factor model, two alternative models were tested. A six-item single factor identified in a previous study with an American community sample showed the best fit (RMSEA = 0.04; GFI = 0.99; AGFI = 0.98; CFI = 0.98; χ(2)/gl = 2.71). The internal consistency for the six-item version was acceptable (ω = .71), and the construct validity with anxiety (r = .53) and depression (r = .38) measures was adequate.
The six-item version of the CSI demonstrated to be a reliable measure for assessing somatization symptoms in Spanish children.
儿童躯体化量表（CSI）已被证明是一种评估儿科患者躯体症状的合适工具，但需要进一步研究来评估其在社区人群中的心理测量特性。
本研究的目的是在非临床的西班牙儿童样本中检验该工具的心理测量特性和因子结构。
对 1111 名 8 至 12 岁的西班牙儿童进行了 CSI 的 24 项版本和两种焦虑和抑郁的自评量表的测试。
探索性分析表明，该量表的因子结构由三个因子组成：假性神经病症状、胃肠道症状和疼痛。由于验证性分析表明三因子模型拟合不良，因此测试了两种替代模型。在一项之前针对美国社区样本的研究中确定的六分量单因子模型表现出最佳的拟合度（RMSEA = 0.04；GFI = 0.99；AGFI = 0.98；CFI = 0.98；χ(2)/gl = 2.71）。六分量版本的内部一致性可接受（ω =.71），与焦虑（r =.53）和抑郁（r =.38）测量的结构效度也足够。
CSI 的六分量版本是评估西班牙儿童躯体化症状的可靠工具。
