Systemizing Quotient–Revised

Last updated on July 30, 2021

The Systemizing Quotient–Revised (SQ-R) is a self-report questionnaire comprising 75 forced-choice format questions, which is used to assess so-called systemizing cognitive styles. Systemizing is the drive to analyze or construct systems.

Taking the test

You don’t need to create an account, but you need to fill in age, gender, and diagnostic status. Click the “I accept” button to consent to your test results’ potential use for research purposes.

The SQ-R consists of 75 statements, giving you 4 choices for each statement:

  1. Strongly agree
  2. Slightly agree
  3. Slightly disagree
  4. Strongly disagree

Scoring

  • Scoring range: 0–150
  • Threshold score: 75

In the table below, you can see the average scores of autistic people and neurotypicals.

In the graph below, you can see how autistic (blue) and non-autistic (tan) men (dashed lines) and women (solid lines) score on the SQ-R.

Validity

The ability of the empathizing–systemizing (E–S) theory to predict autism is under debate. The scores of autistics on the Empathizing Quotient questionnaire and the Systemizing Quotient questionnaire show a significant difference, meaning there is validity to the test.

Discussion

Natalie:

The negative questions were a problem for me, not because they were hard to understand, but because I kept misreading them. In essence, when my brain took out the negative, I realized that my answer was the opposite of what it should be because I had read it as the positive. Aside from that, the statements were simple and clear.

I appreciate that Simon Baron-Cohen has produced several theories as well as tests. However, his tests don’t always test what the names suggest. For example, the Empathy Quotient measures social and communication skills as opposed to empathy. Some of Simon’s theories must be based on his thoughts about autism, rather than based on speaking to autistics.

I scored 44, which was far below either the average autistic or neurotypical scores!

Kendall:

As with other questionnaires, statements regarding whether something is easy or difficult can be hard for me—I have no way to contrast or qualify the point. The options of agree or disagree concerning negative statements I found much easier to make rather than recursive replies such as rarely or always. The wording is clear, concise, and readily understood, making the test quick and simple.


Scoring details

On the following 39 items, ‘strongly agree’ responses score 2 points, and ‘slightly agree’ responses score 1 point:

1, 2, 4, 5, 7, 9, 11, 12, 13, 14, 16, 18, 19, 20, 21, 23, 25, 27, 29, 30, 32, 36, 38, 41, 42, 43, 46, 50, 53, 55, 60, 61, 62, 66, 68, 69, 72, 74 and 75.

On the following 36 items, ‘strongly disagree’ responses score 2 points and ‘slightly disagree’ responses score 1 point:

3, 6, 8, 10, 15, 17, 22, 24, 26, 28, 31, 33, 34, 35, 37, 39, 40, 44, 45, 47, 48, 49, 51, 52, 54, 56, 57, 58, 59, 63, 64, 65, 67, 70, 71 and 73.

Since there were 75 items and each could be scored with a maximum of 2 points, the maximum score on the instrument was 150 and the minimum was zero.
