Diagnosis Disclosure Support Intervention Program for Caregivers of Children With ASD

As school-aged children with autism spectrum disorder begin to recognize differences between themselves and their neurotypical peers, they develop questions regarding their identity and belonging. During this critical developmental period, receiving a clear and supportive explanation of their diagnosis can promote self-understanding, encourage self-advocacy, and enhance psychosocial adjustment. However, caregivers often face significant barriers to disclosing the diagnosis, stemming from fear of stigma, uncertainty about appropriate timing and language, and concerns about causing emotional distress. As a result, caregivers may delay or avoid disclosure, despite potential benefits for the child. Therefore, developing evidence-based interventions to support caregivers in diagnosis disclosure is significant, yet few studies offer guidance for caregivers, leaving disclosure decisions and processes largely to individual families.

The purpose of this randomized controlled pilot study is to develop and evaluate an online diagnosis disclosure support intervention for caregivers of 7- to 12-year-old children with ASD in South Korea, a developmental period when children go through increasing cognitive, social, and identity-related challenges. This study pursues three objectives: (1) to evaluate the acceptability and feasibility of the diagnosis disclosure support intervention; (2) to examine clinically meaningful effects on caregiver's outcomes across domains such as psychological well-being and psychosocial adjustment, parenting competence and attitudes, and autism-related knowledge and social perceptions; and (3) to assess the sustainability of these effects through a one-month follow-up after program completion.

40 caregivers of children with ASD enrolled in mainstream schools (grades 2-6) in South Korea will be recruited and randomly assigned to either an intervention group (n=20) or a waitlist control group (n=20). The intervention group will participate in a five-week, online group-based diagnosis disclosure support program consisting of weekly 60-minute sessions, which will be recorded for fidelity monitoring. The waitlist control group will receive an abbreviated one-session online seminar and program materials upon completion of the final follow-up assessment. Both groups will complete online self-report measures at three timepoints: baseline (T1), immediately following the intervention group's program completion (T2), and at a one-month follow-up (T3). This study holds the potential to improve caregivers' well-being and support healthy family communication by providing evidence-based guidance to facilitate developmentally appropriate disclosure for children with ASD in South Korea.
