The Strengths and Difficulties Questionnaire (SDQ) is a well-known measuring instrument widely used for the assessment of mental health in children and adolescents. Relatively few studies have analysed the factor structure, the measurement invariance, and the internal consistency, including the information function of the SDQ in its parent version. The study included a large sample (N = 3828) from the Spanish National Survey (2016 were male; 52.7%). Mean age was 9.13 (SD = 3.21) with ages ranging from 4 to 14. The level of internal consistency of the scores for the Total difficulties score was 0.84, ranging between 0.75 and 0.78 for the SDQ subscales. Results from the confirmatory factor analysis showed a five-factor model as the most appropriate. Nonetheless, the fit indices were inadequate and different modifications were needed. The hypothesis of measurement invariance of the SDQ scores across gender and educational level was supported. The present study allows us to affirm that the SDQ, parent's version form, appears to be an adequate tool for the screening of emotional and behavioural problems for children and adolescents. Future research should analyse the SDQ at cross-cultural level, incorporating novel psychometric frameworks and new mental health classifications.
长处与困难问卷（SDQ）是一种广为人知的测量工具，常用于评估儿童和青少年的心理健康。相对较少的研究分析了 SDQ 的因子结构、测量不变性和内部一致性，包括其家长版的 SDQ 的信息功能。该研究包括来自西班牙全国调查的大样本（N=3828；男性占 52.7%）。平均年龄为 9.13（SD=3.21），年龄范围为 4 至 14 岁。总分的得分内部一致性为 0.84，SDQ 分量表的范围在 0.75 到 0.78 之间。验证性因子分析的结果表明，五因素模型是最合适的。尽管如此，拟合指数仍然不充分，需要进行不同的修改。SDQ 分数在性别和教育水平上的测量不变性假设得到了支持。本研究可以肯定的是，家长版的 SDQ 似乎是一种评估儿童和青少年情绪和行为问题的有效工具。未来的研究应该在跨文化层面上分析 SDQ，纳入新的心理测量框架和新的心理健康分类。
