Autism Spectrum Disorder (ASD) is diagnosed clinically, based on information gathered from a detailed history and the observation of specific characteristic behaviours. At Threshold Psychology we attempt to use a family-centered approach, whenever possible, to ASD assessment because a substantial amount of time and care is required to listen to and talk with parents/caregivers and other family members. Understanding the child’s family and medical history, along with current behaviours and individual and family treatment goals, is central to family-centered care. 

Assessment for ASD at Threshold Psychology often involves the following process:

  1. Review of the child’s cumulative record (e.g., report cards, previous assessments, school-based services, etc.).

  2. Review of any reports/assessments previously completed.

  3. Administration of the Autism Diagnostic Interview – Revised (ADI-R) which is a structured interview designed to provide a full range of information needed to assist in the assessment of ASD. This takes approximately 2 to 2 ½ hours.

  4. Administration of the Autism Diagnostic Observation Schedule – Second Edition (ADOS-2) which is a semi-structured, standardized assessment of communication, social interaction, play/imagination, and restricted and repetitive behaviours for children. This takes approximately 1 hour to complete.

  5. Interview with your child’s classroom teacher, when needed.

  6. Consultation with other professionals (e.g., pediatrician, school personnel) as needed.

  7. Feedback session with parent(s)/caregiver(s) to review results and recommendations.

We provide assessments for ASD to children ages 5 to 18. The fee for this assessment is approximately $2100 which is consistent with other psychologists in Nova Scotia.
