The Strength and Difficulties Questionnaire (SDQ) is widely used internationally, however less so in preschool populations and validations studies are thus needed. This study examined the psychometric properties of the Norwegian version parent report of the SDQ - preschool version (SDQ 2-4).
Parents of 289 Norwegian children in the age span 1-6 years old filled out the SDQ 2-4, the Child Behavior Checklist (CBCL), and background information. Internal consistency, factor structure, and convergent validity were assessed.
The results showed satisfying internal consistency for the total difficulties score, but worse for some of the subscales. The five-factor structure showed a good fit. Good convergent and divergent validity was found in terms of correlations with CBCL. Sex differences were found on all scales, boys scoring higher on all problem scales.
The SDQ 2-4 can be a promising instrument to screen for emotional and behavioral difficulties among Norwegian preschoolers, particularly in high-risk populations.
《长处和困难问卷》（SDQ）在国际上被广泛使用，但在学龄前人群中的使用较少，因此需要进行验证研究。本研究旨在检验挪威版家长报告的 SDQ-学龄前版（SDQ 2-4）的心理测量特性。
289 名年龄在 1-6 岁的挪威儿童的家长填写了 SDQ 2-4、《儿童行为检查表》（CBCL）和背景信息。评估了内部一致性、因子结构和聚合效度。
结果显示，总困难得分的内部一致性令人满意，但一些分量表的内部一致性较差。五因素结构具有良好的拟合度。与 CBCL 的相关性表明具有良好的聚合和发散效度。在所有量表上都发现了性别差异，男孩在所有问题量表上的得分都较高。
SDQ 2-4 可作为一种有前途的工具，用于筛查挪威学龄前儿童的情绪和行为困难，特别是在高风险人群中。
