Primary use / Purpose:
Although empathy is a very important skill in social functioning it is difficult to conceptualise. While previous measures of empathy have been proposed, the empathy quotient (EQ) focuses on the differences in the skill between normal-functioning adults and adults with autism spectrum disorders. It is a short 40 item likert-type measure.
Reliability and validity are explored in Lawrence, Shaw, Baker,Baron-Cohen, and David (2004)
