CASD Methodology

Covers 6 major groups of traits:

• Social interaction: difficulty making eye contact, inability to play together, lack of social connections.
• Verbal and nonverbal communication: speech delay, echolalia, inability to understand nonverbal cues.
• Limited, repetitive interests and behaviors: stereotyped movements, attachment to certain objects, ritualistic behavior.
• Sensory impairments: increased or decreased sensitivity to sensory stimuli.
• Cognitive impairments: learning difficulties, inability to generalize skills.
• Associated problems: ADHD, anxiety, epilepsy.

The CASD consists of 30 questions, each of which assesses the presence or absence of a symptom.

Takes 15-20 minutes to complete.

Can be completed by:

• Parents: knowing the child’s developmental history and behavior allows them to answer the questions most accurately.
• Teachers: observing the child in a learning environment may reveal additional symptoms.
• Specialists: psychologists, psychiatrists, speech therapists.

Advantages of CASD:

• High accuracy: CASD identifies children with ASD with 99.5% reliability.
• Reliability: Studies have shown that CASD is 93-98% consistent with widely recognized methods of diagnosing ASD, and 90% consistent with the diagnosis of doctors and parents.
• Ease of use: the CASD is easy to complete and requires no specialized knowledge.
• Versatility: The CASD can be used for children of any age, cognitive level, and severity of the disorder.
• Concise: The CASD allows for rapid screening for autism.
