A New Real-Life Test for Reciprocity in Autistic Adults: The Interactive Drawing Test

Area of Science:

• Psychology
• Neurodevelopmental Disorders
• Clinical Assessment

Background:

• Impaired social-emotional reciprocity is a core characteristic of Autism Spectrum Disorder (ASD).
• Assessing reciprocity deficits can be challenging, especially in intelligent adults.
• Current diagnostic tools may lack sensitivity for detecting subtle reciprocity impairments.

Purpose of the Study:

• To evaluate the Interactive Drawing Test (IDT) as a measure of social-emotional reciprocity in adults with and without ASD.
• To determine if the IDT can differentiate between normally intelligent adults with ASD and their neurotypical peers.

Main Methods:

• The Interactive Drawing Test (IDT) was administered to 19 adults with ASD and 18 neurotypical adults of average intelligence.
• Participants engaged in a joint drawing task with an examiner, with spontaneous non-verbal interactions recorded.
• Reciprocity was assessed based on the quantity and quality of contributions to the drawing, including meaningful additions to examiner-initiated elements.

Main Results:

• Adults with ASD scored lower on the IDT's total reciprocity score compared to the control group.
• Autistic participants demonstrated less engagement in joint drawing, particularly when the examiner initiated a topic.
• The IDT identified subtle, characteristic differences in reciprocal behavior associated with ASD in adults.

Conclusions:

• The IDT is a promising tool for assessing social-emotional reciprocity in adults with ASD and average intelligence.
• The test's ability to capture both quantity and quality of reciprocal behavior aids in differentiating ASD.
• Further research with larger samples is needed to establish the IDT's psychometric properties for adult ASD diagnosis.
