Monteiro Interview Guidelines for Diagnosing Asperger’s Syndrome (MIGDAS)

The Monteiro Interview Guidelines for Diagnosing Asperger’s Syndrome (MIGDAS; Monteiro, 2008) is a qualitative assessment tool designed for use by school-based evaluation teams to assess Asperger Syndrome in children and adolescents.


The MIGDAS consists of three tools: a Pre-Interview Checklist, Parent and Teacher Interview, and Diagnostic Student Interview. Together, these tools help teams gather qualitative information to assist in the diagnostic process. Teams first complete the Pre-Interview Checklist, a brief yes/no questionnaire to help determine the need for an evaluation. The remaining interviews (teacher, parent, and student) are completed only when a need has been identified. After completion of the evaluation, teams discuss their qualitative observations and interpret the results.
