目的:自闭症谱系障碍(ASD)是一种神经发育障碍,其特征是社会交往困难和重复行为或兴趣受限。应用行为分析(ABA)已被证明可以显着改善自闭症谱系个体的结果。然而,关于访问的挑战,成本,提供者短缺仍然是治疗交付的障碍。为此,父母被培训为父母行为技术人员(pBTs),改善对ABA的访问,并授权父母在自己的家中提供ABA治疗。我们假设,与诊断为轻度或中度ASD的患者相比,诊断为重度ASD的患者在获得技能方面的总体成功率将获得最大的提高。我们的次要假设是,具有综合治疗计划(>25-40小时/周)的患者将比具有集中治疗计划(小于或等于25小时/周)的患者在技能获取方面表现出更大的增益。方法:这种纵向,回顾性图表综述评估了243例2~18岁患者的数据,这些患者在我们的pBT治疗模式下接受了至少3个月的ABA治疗.患者通过使用规定的ABA治疗进行分层,年龄,ASD严重程度(根据精神疾病诊断和统计手册,第五版),和治疗计划类型(综合与专注)。通过检查获得技能的成功率来评估患者的结果,在整体和特定的重点领域(沟通,情绪调节,执行功能,和社交技能)。
结果:在pBT模型中接受治疗的患者在技能获取方面表现出整体和特定重点领域的显着进步。无论队列分层。患有严重ASD的患者比患有轻度或中度ASD的患者显示出更大的整体技能获得增益。此外,采用综合治疗计划的患者比采用重点治疗计划的患者获益显著.
结论:pBT模型实现了高治疗利用率的持续水平和患者目标的进展。患者在整体和特定重点领域的技能获取成功率方面均有显着提高,无论他们的治疗利用水平。这项研究表明,我们的pBT模型ABA处理递送导致通信的持续改善,情绪调节,执行功能,以及自闭症患者的社交技能,特别是对于那些症状更严重的人和那些遵循综合治疗计划的人。
OBJECTIVE: Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by social communication difficulties and restricted repetitive behaviors or interests. Applied behavior analysis (ABA) has been shown to significantly improve outcomes for individuals on the autism spectrum. However, challenges regarding access, cost, and provider shortages remain obstacles to treatment delivery. To this end, parents were trained as parent behavior technicians (pBTs), improving access to ABA, and empowering parents to provide ABA treatment in their own homes. We hypothesized that patients diagnosed with severe ASD would achieve the largest gains in overall success rates toward skill acquisition in comparison to patients diagnosed with mild or moderate ASD. Our secondary hypothesis was that patients with comprehensive treatment plans (>25-40 hours/week) would show greater gains in skill acquisition than those with focused treatment plans (less than or equal to 25 hours/week). Methods: This longitudinal, retrospective chart review evaluated data from 243 patients aged two to 18 years who received at least three months of ABA within our pBT treatment delivery model. Patients were stratified by utilization of prescribed ABA treatment, age, ASD severity (per the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), and treatment plan type (comprehensive vs. focused). Patient outcomes were assessed by examining success rates in acquiring skills, both overall and in specific focus areas (communication, emotional regulation, executive functioning, and social skills).
RESULTS: Patients receiving treatment within the pBT model demonstrated significant progress in skill acquisition both overall and within specific focus areas, regardless of cohort stratification. Patients with severe ASD showed greater overall skill acquisition gains than those with mild or moderate ASD. In addition, patients with comprehensive treatment plans showed significantly greater gains than those with focused treatment plans.
CONCLUSIONS: The pBT model achieved both sustained levels of high treatment utilization and progress toward patient goals. Patients showed significant gains in success rates of skill acquisition both overall and in specific focus areas, regardless of their level of treatment utilization. This study reveals that our pBT model of ABA treatment delivery leads to consistent improvements in communication, emotional regulation, executive functioning, and social skills across patients on the autism spectrum, particularly for those with more severe symptoms and those following comprehensive treatment plans.
