Content of the questionnaire
Target audienceChildren
ApplicationThe EQ-SQ has been developed to measure the empathizing quotient and systemizing quotient among children between the age of 4 and 11. The EQ component has found to be capable of detecting the poor empathizing typically associated with ASC. The SQ component is predictive of the high involvement with systems and processes aspect of ASC.
CompositionThe combined questionnaire has 55 items (27 on EQ, 28 on SQ), with four alternatives for each question. The parent indicates how strongly they agree with each statement about their child by selecting one of several options: ‘definitely agree’, ‘slightly agree’, ‘slightly disagree’, or ‘definitely disagree’.
ScoringScores are calculated by adding up items. EQ scores can range between 0-54 and SQ between 0-56.
Psychometric properties
GeneralResearch has shown that girls scored significantly higher on the EQ-C, and boys scored significantly higher on the SQ-C. Children with Autism Spectrum Conditions (ASC) scored significantly lower on the EQ-C, and significantly higher on the SQ-C, compared to typical boys. Research shows high coefficients for empathy items (a = 0.93) as well as for systemizing items (a = 0.78).
