From Diagnosis to Empowerment: A Case Study of Parent-Mediated Intervention in Autism Spectrum Disorder

Background: Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterised by persistent difficulties in social communication and restricted, repetitive patterns of behaviour, typically emerging in early childhood. While early and multidisciplinary intervention is critical for improving developmental outcomes, receiving an ASD diagnosis often places a significant emotional and psychological burden on parents. Supporting parental coping and active involvement in intervention is therefore an essential component of comprehensive ASD care. Methods: This qualitative single-case study examines the journey of parents whose child was diagnosed with ASD at 2.8 years of age. The study explores parent’s early emotional responses to the diagnosis, the challenges they encountered, and their evolving understanding of their child’s needs. Parent-mediated intervention (PMI) was implemented through a collaborative therapist–parent approach targeting adaptive skills, social interaction, communication, and sensory regulation. Child progress was documented longitudinally using standardised developmental and autism-specific measures, alongside parental narratives obtained through semi-structured interviews. Results: Over the course of intervention, the child demonstrated improvements in adaptive behaviour, functional communication, social engagement, and a reduction in sensory-related difficulties. Parallel to these developmental gains, parents progressed from initial distress and uncertainty towards increased resilience, confidence, and active participation in their child’s intervention. Parents reported enhanced understanding of their child’s strengths and needs, greater competence in managing challenges, and a sense of empowerment in their care giving role. Conclusion: This case study highlights the potential benefits of parent-mediated intervention in promoting both child skill development and parental empowerment. The findings underscore the clinical importance of integrating structured parent training and emotional support as part of ASD intervention, positioning parents as collaborative partners in their child’s developmental journey.
