Behavioral and emotional problems in infants and toddlers are common, often persist and put children at risk of later mental health problems. Reliable, efficient, and sensitive tools are needed to identify young children who may benefit from further assessment and support. The Strengths and Difficulties Questionnaire (SDQ), offers a brief, convenient means of screening for early problems, however, it lacks psychometric validation in infants. The aim of this study was to assess the validity and reliability of the SDQ in children aged 12–24 months. Ninety-three participants, with children aged 12–24 months, completed the SDQ and Child Behavior Checklist (CBCL) online. Concurrent validity of the SDQ was assessed through comparison with the CBCL. The results demonstrated that key subscales of the SDQ and CBCL were significantly correlated (r range= −.19 to –.57). Key SDQ subscales showed moderate reliability (Cronbach's alpha range = .38–.79, mean inter-item correlation range = .06–.43). The SDQ shows promising reliability and validity as a measure for rating the behavior of 12–24-months-old children, particularly for externalizing symptoms. Further research is needed to assess its predictive utility.

使用优势和困难问卷评估 12-24 个月儿童的行为

婴幼儿的行为和情绪问题很常见，而且常常持续存在，并使儿童面临日后出现心理健康问题的风险。需要可靠、高效和灵敏的工具来识别可能从进一步评估和支持中受益的幼儿。优势和困难问卷 (SDQ) 提供了一种简单、方便的筛查早期问题的方法，但是，它缺乏对婴儿的心理测量验证。本研究的目的是评估 SDQ 在 12-24 个月儿童中的有效性和可靠性。93 名儿童年龄在 12-24 个月之间的参与者在线完成了 SDQ 和儿童行为检查表 (CBCL)。通过与 CBCL 的比较来评估 SDQ 的同时有效性。结果表明，SDQ和CBCL的关键分量表显着相关（r范围= -.19 到 –.57）。关键的 SDQ 分量表显示出中等可靠性（Cronbach 的 alpha 范围 = .38–.79，平均项目间相关范围 = .06–.43）。SDQ 作为衡量 12-24 个月大儿童行为的衡量标准，显示出有希望的信度和效度，尤其是外化症状。需要进一步研究来评估其预测效用。
