We aimed to construct and validate a shortened form of the developmental, diagnostic and dimensional interview (3Di), a parent report interview for assessing and diagnosing autistic spectrum disorders (ASDs). Data from 879 children and young people were used. In half of the sample (n = 440) reliability analysis was used to identify 3Di items that best measured each dimension of the autism triad. This informed the construction of a shortened (53 item) 3Di, which was then validated on subjects not used in the reliability analysis (n = 439). This involved comparison with scores from the original 3Di algorithm and, in a subsample (n = 29), with the autism diagnostic interview-revised (ADI-R). Agreement of the new shortened 3Di with the 3Di's original algorithm was excellent in both dimensional and categorical terms. Agreement on caseness (27 out of 29) with the ADI-R was also strong. The new 3Di short version is less than half as long as the original version and outputs very similar scores. It will be useful to clinicians and researchers for obtaining a dimensional autism assessment in less than 45 minutes.
我们旨在构建和验证发展性、诊断性和维度访谈（3Di）的简化形式，这是一种用于评估和诊断自闭症谱系障碍（ASD）的家长报告访谈。使用了 879 名儿童和青少年的数据。在样本的一半（n=440）中，可靠性分析用于确定最佳测量自闭症三联征每个维度的 3Di 项目。这为构建一个缩短的（53 项）3Di 提供了信息，然后在未用于可靠性分析的受试者（n=439）上对其进行验证。这涉及与原始 3Di 算法的分数进行比较，以及在一个子样本（n=29）中与修订后的自闭症诊断访谈（ADI-R）进行比较。新的缩短 3Di 在维度和分类方面与 3Di 的原始算法具有极好的一致性。与 ADI-R 的病例一致性（27 例中的 29 例）也很强。新的 3Di 短版本比原始版本短一半以上，输出非常相似的分数。它将对临床医生和研究人员在不到 45 分钟的时间内获得维度自闭症评估非常有用。
