We conducted a follow-up investigation of a two-site randomized controlled trial in the United States. We examined whether the treatment effects in a culturally tailored parent education program for Latinx families of children with autism spectrum disorder were maintained over time. Using linear mixed models, we compared differences in parent and child outcomes across three timepoints: baseline, 4 months after baseline (Time 2), and 8 months after baseline (T3). Parent outcomes included family empowerment, self-reported confidence in, and frequency of using evidence-based strategies. Child outcomes included parent-reported challenging behaviors, social communication impairments, and the number of services received. Participants were 109 Latina mothers (intervention = 54, control = 55) of children with autism spectrum disorder. After intervention at both Time 2 and Time 3 in both sites, mothers in the intervention groups reported significantly greater confidence in and frequency of using evidence-based strategies, and that their child received significantly more services. We also found that there were treatment differences across the two study sites in several outcomes. The intervention for Latinx parents of children with autism spectrum disorder was efficacious and could be maintained, and that site-specific policy and service differences may need to be examined in future research to inform dissemination and implementation.
我们对美国的一项两站点随机对照试验进行了随访调查。我们考察了针对自闭症谱系障碍儿童的拉丁裔美国家庭的文化适应型家长教育计划的治疗效果是否随着时间的推移而保持。我们使用线性混合模型，比较了三个时间点（基线、基线后 4 个月（时间 2）和基线后 8 个月（T3））的家长和儿童结果的差异。家长结果包括家庭赋权、自我报告的信心和使用循证策略的频率。儿童结果包括父母报告的挑战行为、社交沟通障碍以及所接受的服务数量。参与者是 109 名拉丁裔母亲（干预组 54 名，对照组 55 名）的自闭症谱系障碍儿童。在两个地点的干预时间 2 和时间 3 之后，干预组的母亲报告说，他们对循证策略的信心和使用频率显著提高，而且他们的孩子接受的服务也显著增加。我们还发现，在几个结果方面，两个研究地点存在治疗差异。针对自闭症谱系障碍儿童的拉丁裔父母的干预措施是有效的，可以维持下去，未来的研究可能需要检查特定地点的政策和服务差异，以为推广和实施提供信息。
