It is important to research the causes and prevalence of ASD and to better understand early identification and diagnostic techniques. However, while this kind of research is providing better medical understanding and hope for the future, thousands of Canadians with ASD, young and old and their families are presently requiring better quality services and treatment options to manage their conditions and improve the quality of their lives.
This page highlights current research initiatives relating to the development of better outcomes for children, youths and adults with ASDs. This includes research into the design of improved life-span health and social services, delivery models and best practices in treatment.
In general, more research is needed to:
- Further develop current treatment models and interventions and to investigate new approaches
- Determine which approach works for which individual and at which stage of their development
- Deepen understanding of ASDs across the lifespan
- Assess functioning and quality of life for children, youth and adults with ASD
- Assess behavioural, psychological, psychosocial and psycho-educational treatments
- Determine the communication needs and differences for individuals with ASD and evaluate treatment outcomes with respect to speech, language and communication skills
- Better understand the needs of families
- Investigate methods of cross-discipline cooperation and effective service delivery (e.g., guidelines, sharing of knowledge and training needs)
- Understand the barriers to accessibility of treatments for ASD
Canadian Research into Treatment and Intervention
The Behavioural/Developmental Continuum of Interventions for Autism Spectrum Disorder: A Systematic Review
At the Alberta Centre for Child, Family and Community Research, a team of co-investigators, working collaboratively under the leadership of Drs. Brenda Clark and Veronica Smith, (Co-Principal Investigators of the study) is currently undertaking a systematic review of the research evidence supporting the effectiveness of various behavioural/developmental-based interventions for individuals with autism spectrum disorder. Along with other stakeholders, Autism Society Canada is acting in an advisory role on this project.
A wide range of behavioural/developmental interventions and treatments are currently being used to help people with ASDs function in three core areas: reciprocal social interaction, communication, and restricted, stereotyped, repetitive behaviour. A Canadian-based review of the best interventions, treatment approaches and services for people with ASDs is long overdue and should be very useful in decision-making about the provision of services to families of individuals with ASD. Health professionals, policy makers, families and caregivers are responsible for choosing or implementing interventions, but many do not feel they have sufficient evidence on which to base these decisions.
Hopefully the results of this research will provide much needed guidance in two key areas:
- how to match existing interventions with the needs of individual children, and,
- the appropriate balance and sequence of interventions over the lifespan of an individual with ASD.
Advocates of many early interventions report substantial improvement in certain outcomes, but there is little information about what component of the intervention causes the improvement and how or whether particular improvements will affect the person’s functioning over time.
Canadian Autism Intervention Research Network (CAIRN) Studies
Pathways to Better Outcomes Study
The Canadian Autism Intervention Research Network (CAIRN) is conducting a cross-Canada study to identify the factors that promote healthy development in children with Autism Spectrum Disorders. More than 500 children from Nova Scotia, Quebec, Ontario, and B.C. are participating in the study. This will be the largest study of its kind ever carried out anywhere in the world and it is expected to provide a wealth of new information. The study aims to describe the developmental pathways of children with ASD and identify what services, what interventions, and what factors promote the healthiest development among these children. Instead of only focusing on the deficits of children with ASD, the researchers are also focusing on individual strengths that allow kids with ASD to be resilient in the face of challenges.
Follow-up Study – Developmental Trajectories Among Children with Pervasive Developmental Disorders
CAIRN study is looking at whether children with Asperger syndrome (AS) have a different outcome than children with high-functioning (HF) autism, and also investigating factors that enhance the life quality of these children and their families. It is the most comprehensive and longest-lasting follow-up study of children with HF autism in the world and the only study that has focused on Asperger syndrome.
Canadian Early Intervention Research Project
(View study description) McGill University is spearheading this project in partnership with the Yaldei Developmental Centre (YDC). The project is being conducted through the Faculty of Education, in the Department of Educational and Counseling Psychology (ECP). The project goals are to determine the efficacy of Early Childhood Intervention (EI) programs that impact the health, wellness, and environment of families with children who have developmental delays; and to engage practitioners and policy makers in early childhood development to reassess and facilitate the change of current policies and practices in this area where necessary.
- Early diagnosis
- Effective early treatment
- Adequate family supports
