|Application||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.|
|Composition||The questionnaire contains 75 statements with four answer options, varying from ‘definitely agree’ to ‘definitely disagree’.|
|Scoring||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.|
|General||Research has shown a (slight) negative correlation with empathy quotient. SQ has a good internal consistency (0.903).|
