The Development and Feasibility Evaluation of a Module in Improving Functioning of Children with Autism Spectrum Disorder (ASD)

Background and Context

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterised by persistent deficits in social communication and social interaction, accompanied by restricted, repetitive patterns of behaviour, interests, or activities. The prevalence of ASD has increased substantially worldwide in recent decades, with current estimates suggesting approximately 1 in 100 to 1 in 54 children are affected, depending on the population studied and diagnostic criteria applied. In Malaysia, while precise prevalence data remains limited, increasing awareness and improved diagnostic capacity have led to a growing number of identified cases.

Children with ASD frequently experience functional limitations across multiple domains, including sensory processing, motor coordination, self-care, social participation, and academic performance. These limitations extend beyond the core diagnostic features of the disorder and significantly impact the child’s ability to participate in everyday activities and routines. Occupational therapy is a key profession involved in addressing these functional challenges, using activity-based and sensory-based interventions to promote independence and participation.

Despite the availability of various intervention approaches for ASD, there has been a need for structured, culturally appropriate modules that can be systematically implemented and evaluated in the Malaysian clinical context. Many existing programmes were developed in Western countries and may not fully account for the cultural practices, family structures, and service delivery models characteristic of Malaysia.

Module Development Process

The development of the intervention module followed a systematic approach, incorporating evidence from the international literature on ASD interventions with input from Malaysian clinicians, educators, and families. The module was designed to be implemented by trained occupational therapists and addressed functional limitations across multiple domains relevant to children with ASD.

Key components of the module included structured activities targeting sensory processing difficulties, which are experienced by the majority of children with ASD and can significantly affect their ability to engage in daily routines. Motor skill development activities addressed both fine motor and gross motor challenges that may limit participation in self-care, play, and academic tasks. Daily living skills training focused on building independence in age-appropriate self-care activities such as dressing, feeding, and personal hygiene.

The module also incorporated strategies for supporting social participation, recognising that the social communication difficulties central to ASD require explicit instruction and structured opportunities for practice. Family involvement was embedded throughout the module, reflecting the evidence that parent-implemented interventions enhance generalisation and maintenance of skills.

Feasibility Evaluation

The feasibility evaluation assessed multiple aspects of the module’s practicality for implementation in Malaysian settings. This included examining whether the module could be delivered within typical clinical time constraints, whether the required materials and resources were readily available, whether therapists found the module instructions clear and implementable, and whether families found the approach acceptable and relevant to their priorities.

Results indicated that the module was feasible for implementation in Malaysian clinical and community rehabilitation settings. Therapists reported that the structured format facilitated consistent delivery of evidence-based interventions, while allowing sufficient flexibility to accommodate individual variations in children’s needs and abilities. Families expressed positive perceptions of the module’s relevance and accessibility.

Implications for Rehabilitation Services in Malaysia

Malaysia’s rehabilitation services for children with ASD have expanded in recent years through government initiatives, community-based rehabilitation centres, and private practice. However, variation in service quality and the availability of evidence-based intervention programmes remains a concern. A standardised module that has been developed for and evaluated in the Malaysian context addresses this gap by providing a framework for consistent, evidence-based practice.

The module’s design for implementation by occupational therapists aligns with the professional workforce available in Malaysian healthcare facilities. By incorporating cultural considerations and practical constraints relevant to the Malaysian setting, the module enhances the ecological validity of the intervention approach.

Broader Context of ASD Research

Internationally, there is growing recognition that ASD interventions must be evaluated not only for their effectiveness in reducing symptoms but also for their impact on everyday functioning and quality of life. The International Classification of Functioning, Disability and Health (ICF) framework, promoted by the World Health Organisation, emphasises the importance of functioning and participation alongside impairment-based outcomes. This module aligns with this framework by targeting functional outcomes that are meaningful to children and families.

Limitations

The feasibility evaluation represents an early phase of intervention development and does not provide evidence of clinical effectiveness. Without a comparison group, it is not possible to determine whether improvements observed during module implementation are attributable to the intervention or to natural developmental progress. The study sample and settings may not represent the full diversity of Malaysian children with ASD and their service contexts.

Significance and Future Directions

This study establishes the foundation for future randomised controlled trials to evaluate the effectiveness of the module in improving functioning of children with ASD. By demonstrating feasibility in the Malaysian context, the research justifies the investment of resources required for larger-scale effectiveness studies. The module represents an important contribution to the development of culturally appropriate, evidence-based rehabilitation services for Malaysian children with ASD and their families.
