The Strengths and Difficulties Questionnaire (SDQ) assesses behavioural adjustment in children aged 3 to 16 years. To ascertain the appropriateness of the scale for a specific population, it is important to examine whether the distinctiveness of the scale dimensions can be verified empirically.
Confirmatory factor analysis was used to test explicitly which of three models better explain our data, and whether model fit was improved by the addition of method factors.
Parents of 411 Singaporean kindergartners completed the SDQ.
A four-factor multi-trait multi-method model (Prosocial, Conduct, Hyperactivity, Internalizing and two method factors) provided the best fit to the data. There was strong evidence for convergent and discriminant validity. However, differences in configural loading pattern indicated gender-related differences in the mapping of the SDQ items.
Differences in factor structure across countries and gender may reflect differing conceptions of the underlying dimensions, as well as differences in normative expectations. However, our findings may allow its use as a screening tool to identify Singaporean children at risk of emotional and behavioural difficulties.
优势与困难问卷（SDQ）用于评估3至16岁儿童的行为适应情况。为确定该量表对特定人群的适用性，检验量表维度的独特性是否能通过实证得到验证很重要。
采用验证性因素分析来明确三种模型中哪一种能更好地解释我们的数据，以及添加方法因素是否能改善模型拟合度。
411名新加坡幼儿园儿童的家长完成了SDQ。
一个四因素多特质多方法模型（亲社会、品行、多动、内化及两个方法因素）与数据拟合最佳。有充分证据支持聚合效度和区分效度。然而，构型载荷模式的差异表明SDQ项目映射存在性别差异。
不同国家和性别的因素结构差异可能反映了对潜在维度的不同概念理解以及规范期望的差异。然而，我们的研究结果可能使其可作为一种筛查工具，用于识别有情绪和行为困难风险的新加坡儿童。
