When evaluating a child for autistic spectrum disorders, which of the following is an important first step?

The initial and crucial step in evaluating a child for autistic spectrum disorders involves conducting a comprehensive assessment that often includes a referral for psychological testing. This is essential because psychological testing can provide valuable insights into the child's developmental, behavioral, and cognitive profile. It helps in identifying the presence of autism spectrum disorders by examining the child’s social communication skills, behaviors, and emotional responses, which are critical components of the diagnostic criteria.

Identifying the characteristics of autism through psychological testing allows for a clearer understanding of the child’s needs and can guide further interventions. This step is foundational, as a proper diagnosis affects the subsequent treatment plan and supports the development of targeted strategies that can enhance the child's functioning.

Other assessments, such as family history or speech therapy evaluations, while potentially important, usually follow the psychological assessment to further clarify the child's specific challenges and strengths after an initial diagnosis is obtained.
