SQ-R

Systemizing Quotient — Revised

A 75-item self-report measure of systemizing tendency.

For each statement, select the response that best matches how you feel. Strong responses (Strongly Agree or Strongly Disagree) count more heavily than slight ones.

About the SQ-R

The Systemizing Quotient — Revised measures the drive to analyse, construct, and predict rule-based systems. Systemizing is one pole of the “empathizing–systemizing” framework developed by Baron-Cohen and colleagues. Autistic individuals tend to score higher than average, reflecting a strong drive toward pattern detection and rule extraction.

75 items. Designed for adults. Takes about 15–20 minutes.

Scoring

Each item scores 0, 1, or 2 depending on the strength and direction of the response. “Forward” items score for agreement (Strongly Agree = 2, Slightly Agree = 1); “reverse” items score for disagreement. The total range is 0–150 and a score above 75 suggests a high systemizing drive.

Important: The SQ-R measures systemizing tendency, not ability or intelligence. A high score indicates a strong interest in systems and patterns. It is a screening tool, not a diagnostic instrument.
