In countries with public health insurance, caregivers may face long wait times to access services for children with intellectual and developmental disability. This limited access may compromise the adaptation of the child and their family, especially when specialized services (e.g., early intensive behavioral interventions) are needed to manage problem behaviors. Further, longer wait times can contribute to parental stress and increase problem behaviors in children. Therefore, the purpose of the current study was to evaluate the effectiveness of an online parent training for managing problem behaviors for families awaiting specialized services. Twenty-nine families of children with intellectual and developmental disability participated in a randomized controlled trial with random assignment to a waitlist control (i.e., sixteen families in the experimental group and thirteen in the waitlist group). Our results demonstrated that the online training led to reductions in the frequency of problem behaviors and parenting stress while improving caregivers’ self-efficacy. This study provides preliminary evidence for the utility of an online training to support caregivers of young children with intellectual and developmental disability.

在有公共医疗保险的国家，看护者可能需要等待很长时间才能获得为智力和发育障碍儿童提供的服务。这种有限的访问可能会损害儿童及其家庭的适应能力，尤其是在需要专门服务（例如，早期强化行为干预）来管理问题行为时。此外，较长的等待时间会增加父母的压力并增加孩子的问题行为。因此，本研究的目的是评估在线家长培训在管理等待专业服务的家庭问题行为方面的有效性。29 个智力和发育障碍儿童家庭参加了一项随机对照试验，随机分配到候补名单对照（即，实验组 16 个家庭和候补组 13 个家庭）。我们的结果表明，在线培训可以减少问题行为的频率和养育压力，同时提高照顾者的自我效能感。这项研究为在线培训在支持智力和发育障碍幼儿的照顾者方面的效用提供了初步证据。
