The development of measures of child maltreatment for the Chinese population were limited until the Chinese version of the ISPCAN Child Abuse Screening Tools - Children's Home version (ICAST-CH-C) was proposed. Although the ICAST-CH-C was found to be effective in assessing the scope and prevalence of child maltreatment, it has several potential drawbacks. The time that is required to complete the ICAST-CH-C scale is longer than usual for a 36-item scale, because many of its items have one or more follow-up questions. Moreover, each item requires child victims to recall unpleasant experiences. Both phenomena can cause increases in invalid responses and in turn damage the data quality.
The goal of this study was to propose a short form of the ICAST-CH-C (called the SC-ICAST-CH) to reduce the test length and response time in order to improve the measurement quality.
A dataset from a national survey of 5236 adolescents in Taiwan was used.
A multidimensional version of the rating scale model (MRSM) was fitted to the data. The model parameters were estimated with the ConQuest software.
The results indicated the reliability of the SC-ICAST-CH was fairly good, with only 61 % of the original test length. Disordered thresholds were found in all five subscales; the underlying reasons for this phenomenon need further investigation. Specific cultural differences related to item retention/removal decisions were also discussed.
The efficient, shorter SC-ICAST-CH was shown to be a valid and reliable instrument for assessing the prevalence of child maltreatment.
直到中文版 ISPCAN 儿童虐待筛查工具-儿童之家版（ICAST-CH-C）提出，中国才有了儿童虐待的测量方法。虽然 ICAST-CH-C 被证明在评估儿童虐待的范围和流行程度方面是有效的，但它有几个潜在的缺点。完成 ICAST-CH-C 量表所需的时间比通常的 36 项量表要长，因为它的许多项目都有一个或多个后续问题。此外，每个项目都要求儿童受害者回忆不愉快的经历。这两种现象都会导致无效反应的增加，从而损害数据质量。
本研究的目的是提出 ICAST-CH-C 的简短形式（称为 SC-ICAST-CH），以缩短测试长度和响应时间，从而提高测量质量。
使用了来自台湾 5236 名青少年全国调查的数据集。
拟合多维评分量表模型（MRSM）的数据。使用 ConQuest 软件估计模型参数。
结果表明，SC-ICAST-CH 的可靠性相当好，仅为原始测试长度的 61%。在所有五个分量表中都发现了无序阈值；这种现象的根本原因需要进一步调查。还讨论了与项目保留/删除决策相关的特定文化差异。
高效、更短的 SC-ICAST-CH 被证明是一种有效的、可靠的评估儿童虐待流行程度的工具。
