For whom is the Systemizing Quotient intended?
This self-report questionnaire is suitable for adults.
What does the SQ measure?
Systemizing is defined as the drive to analyse, understand, predict, control and construct rule-based systems. High scores on SQ are typically related to ASC traits.
What does the SQ questionnaire consist of?
The questionnaire contains 75 statements with four answer options, varying from ‘definitely agree’ to ‘definitely disagree’.
How does the SQ scoring work?
Scores are calculated by adding up items. Higher scores indicate more symptoms. Scores can range between 0-175. Higher scores indicate higher tendency to systemize.
Research has shown a (slight) negative correlation with empathy quotient. SQ has a good internal consistency (0.903).
