目的：描述优势和困难问卷（SDQ）的心理测量学特性，SDQ是一种可由父母、教师或青少年完成的3-16岁儿童亲社会行为和精神病理学的简要测量。方法：一项全国性的流行病学样本，包括10，438名5-15岁的英国人，从96%的父母，70%的教师和91%的11-15岁的孩子那里获得了SDQ。对SDQ结果不知情，所有受试者也根据详细访谈措施的临床审查分配DSM-IV诊断。结果：预测的五因素结构（情绪，品行，多动-注意力不集中，同伴，亲社会）得到证实。内化量表和外化量表彼此相对“未受污染”。可靠性总体上是令人满意的，无论是内部一致性（平均克朗巴赫α：0.73），交叉信息相关性（平均值：0.34），或4至6个月后的重测稳定性（平均值：0.62）。SDQ得分高于第90百分位数预测独立诊断的精神疾病的概率大幅增加（平均比值比：父母量表15.7，教师量表15.2，青年量表6.2）。结论：SDQ具有良好的信度和效度，可作为儿童青少年适应能力和心理病理学的简易测量工具。
Objective: To describe the psychometric properties of the Strengths and Difficulties Questionnaire (SDQ), a brief measure of the prosocial behavior and psychopathology of 3-16-year-olds that can be completed by parents, teachers, or youths. Method: A nationwide epidemiological sample of 10,438 British 5-15-year-olds obtained SDQs from 96% of parents, 70% of teachers, and 91% of 11-15-year-olds. Blind to the SDQ findings, all subjects were also assigned DSM-IV diagnoses based on a clinical review of detailed interview measures. Results: The predicted five-factor structure (emotional, conduct, hyperactivity-inattention, peer, prosocial) was confirmed. Internalizing and externalizing scales were relatively "uncontaminated" by one another. Reliability was generally satisfactory, whether judged by internal consistency (mean Cronbach alpha: .73), cross-informant correlation (mean: 0.34), or retest stability after 4 to 6 months (mean: 0.62). SDQ scores above the 90th percentile predicted a substantially raised probability of independently diagnosed psychiatric disorders (mean odds ratio: 15.7 for parent scales, 15.2 for teacher scales, 6.2 for youth scales). Conclusion: The reliability and validity of the SDQ make It a useful brief measure of the adjustment and psychopathology of children and adolescents.
