The Strengths and Difficulties Questionnaire (SDQ) is a frequently used behavioral screening instrument. However, its psychometric properties have been rarely examined among children with intellectual and developmental disabilities (IDD).
The main aims of this study were to examine the internal consistency (i.e., McDonald's Omega), the convergent validity (by correlating the Total difficulties score with the Aberrant Behavior Checklist [ABC]), the divergent validity (by correlating the Total difficulties score with the Vineland Adaptive Behavior Composite; VABS-II Total) and the factorial validity (by the means of confirmatory factor analyses [CFA]) of the SDQ self-report-, parent-, and teacher version in a sample of children with IDD.
Participants were 365 children and adolescents (males n = 238; 65 %) aged 4-18 years (M = 10.11, SD = 3.82) referred for a developmental/neurological assessment to the neuropediatric outpatient clinics in the specialist health services. The SDQ was filled inn by 115 children, 337 parents, and 248 teachers.
McDonald's Omega was overall lowest for the self-report version. Correlations of the SDQ Total difficulties score and the ABC subscales were strongest for the parent version. The results of the CFA indicated best model fit for the six-factor model that included a method factor for all three versions of the SDQ, however, model fit was overall not good.
Further research that examines the psychometric properties of the SDQ among multiple informants in large samples of children with IDD is needed.
《长处和困难问卷》（SDQ）是一种常用的行为筛查工具。然而，其心理测量学特性在智力和发育障碍（ID）儿童中很少被研究。
本研究的主要目的是检验 SDQ 自评、家长报告和教师报告版本的内部一致性（即 McDonald's Omega）、聚合效度（通过与异常行为检查表 [ABC] 的总分相关来衡量）、区分效度（通过与适应行为综合评定量表；VABS-II 总分相关来衡量）和因子效度（通过验证性因素分析 [CFA]）。
参与者为 365 名 4-18 岁（M = 10.11，SD = 3.82）的儿童和青少年（男性 n = 238；65%），他们因发育/神经问题到专科医疗服务的神经儿科门诊就诊。SDQ 由 115 名儿童、337 名家长和 248 名教师填写。
SDQ 自评版本的 McDonald's Omega 总体最低。SDQ 总分与 ABC 子量表的相关性在家长报告版本中最强。CFA 的结果表明，对于包括 SDQ 所有三个版本的方法因子的六因子模型，模型拟合最好，但整体模型拟合不佳。
需要进一步研究在智力和发育障碍儿童的多个知情者中，使用 SDQ 进行心理测量学特性的研究，样本量要大。
