Behavioral questionnaires are commonly used to help identify
autistic behaviors and to evaluate their severity. The
specific test used depends on the health professional's preference and
the child's symptoms. Commonly used assessments include the following.
Modified Checklist for Autism in Toddlers (M-CHAT). This
test is used to evaluate infants who are 16 to 30 months old. The M-CHAT is better than the original CHAT (Checklist
for Autism in Toddlers) for detecting autism. The test continues to be studied
to identify milder autistic symptoms.
Pervasive Developmental Disorder Screening. This questionnaire
is completed by parents to evaluate early signs of autism.
Social Communication Questionnaire. This test is for children 4
years of age and older.
Autism Behavior Checklist. This is a screening tool completed by the child's teacher.
Childhood Autism Rating Scale. This test
rates how much a child's behavior varies from that of other children the same
age (older than 24 months).
Autism Diagnostic Interview. Parents provide information about their child's behaviors
during this wide-ranging, structured interview.
Autism Observation Schedule. During this test, a health professional observes a child as he or she performs
several activities involving communication, social interaction, play,
interests, and other behaviors.
