Autism Spectrum Disorder

What is Autism

Autism Spectrum Disorder (ASD) is a lifelong developmental condition. The common areas of difficulty with autism include, communication, socialisation, restricted or repetitive behaviours, and sensory sensitivities. The severity and extent to which to which daily functioning may be affected can range from mild to severe. 

The Benefits of Assessment

Picton Psychology offers ASD assessments for children aged 6 years and above, adolescents and adults. Research has shown that early diagnosis and treatment provide the best outcomes for people with ASD. Through the use of psychological assessment, we can determine whether or not the individual has ASD and determine how to best tailor treatments to meet your specific needs. Some benefits of assessment include:

  •         Understand sensory sensitivities, social communication, behaviours and emotion regulation and recognition.
  •         Tailor treatment plans and interventions to suit individual needs.
  •         Assist teachers in developing Individual Learning Plans (IPLs).
  •         Prevent negative outcomes at school, including disruptive behaviours, school avoidance or school refusal, and low self-esteem.
  •         Access school based and home based funding.

Test Used for Assessments

The diagnosis of ASD requires a comprehensive assessment process which involves gathering information from a range of sources. Best practice research suggests a comprehensive assessment involves gathering information by administering standardised assessment tools, coupled with a developmental history interview with parents.
