The objective of this research was to assess the efficacy of behavioral therapy interventions in the treatment of autism spectrum disorders (ASD). The study utilized the PubMed and Embase databases to locate randomized controlled trials, quasi-experimental treatment studies, and randomized clinical trial comparisons. The experimental group received treatment based on an applied behavioral approach, such as PECS, DTT, PRT, TEACCH, ESDM, and EIBI. After examining seventeen studies, the researchers found that each type of behavioral intervention had a positive impact. Naturalistic protocols that employed PRT and PECS improved ASD symptoms in general, despite their targeting of particular cognitive domains such as language. ESDM enhanced receptive language, particularly in preschool-aged children. Structured and integrated interventions, like EIBI and TEACCH, improved overall adaptive functioning. Combining DTT with a TEACCH program produced greater benefits in linguistic, affective-social, and personal autonomy domains. However, there is a scarcity of high-quality research available on behavioral interventions for ASD. Further comparative studies are necessary to identify cost-efficient interventions. For example, PRT and PECS significantly improved social communication skills in only 15-40 hours over six months. The authors emphasized the need for continued research and the application of evidence-based interventions in specialized settings.

自闭症谱系障碍行为干预有效性的评估：随机对照试验和准实验研究的系统评价。

本研究的目的是评估行为疗法干预治疗自闭症谱系障碍（ASD）的效果。该研究利用 PubMed 和 Embase 数据库来查找随机对照试验、准实验治疗研究和随机临床试验比较。实验组接受基于应用行为方法的治疗，例如 PECS、DTT、PRT、TEACCH、ESDM 和 EIBI。在检查了十七项研究后，研究人员发现每种类型的行为干预都会产生积极的影响。采用 PRT 和 PECS 的自然主义方案总体上改善了 ASD 症状，尽管它们针对的是语言等特定认知领域。ESDM 增强了接受性语言，尤其是学龄前儿童。EIBI 和 TEACCH 等结构化和综合干预措施改善了整体适应性功能。将 DTT 与 TEACCH 计划相结合，在语言、情感社交和个人自主领域产生了更大的好处。然而，关于自闭症谱系障碍行为干预的高质量研究很少。需要进一步的比较研究来确定具有成本效益的干预措施。例如，PRT 和 PECS 在六个月内仅用 15-40 小时就显着提高了社交沟通技能。作者强调需要继续研究并在专门环境中应用循证干预措施。
