The RAADS-R questionnaire consists of 80 questions designed to assess autism spectrum traits across four domains. This guide walks you through the questionnaire interface and its features.

​
Starting the Questionnaire

1

Read the Introduction

When you first open the application, you’ll see the landing page with:
  • A brief description of the RAADS-R and its four assessment areas
  • Important disclaimers about the screening nature of the tool
  • Privacy information about local data storage
2

Click Begin Questionnaire

Click the blue “Begin Questionnaire” button to start. The first time you do this, you may see a privacy banner asking if you want to save your progress locally.
3

Choose Privacy Settings

The privacy banner offers two options:
  • Save Progress: Stores responses in browser localStorage so you can resume later
  • No Thanks: Proceed without saving (you’ll need to complete in one session)

​
Answering Questions

Each question presents a statement about experiences or behaviors with four response options:
The four response options for every question are:
  • True now and when I was young
  • True only now
  • True only when I was younger than 16
  • Never true

​
Question Card Interface

The question card displays:
  • Question number and total count (e.g., “Question 5 of 80”)
  • The statement text in large, readable font
  • Four radio button options styled as cards
  • Selected answers are highlighted in blue with a ring border
Example question from QuestionCard.tsx:29-35: 
Question 1 of 80
I am a sympathetic person.
Two buttons appear below each question:
  • Returns to the previous question (or landing page if on question 1)
  • Always enabled
  • Keyboard shortcut: Left Arrow key
  • Advances to the next question
  • Only enabled after selecting an answer
  • Changes to “View Results” on the final question (when all 80 are answered)
  • Keyboard shortcut: Right Arrow key (when an answer is selected)

​
Progress Tracking

A visual progress bar appears at the top of the questionnaire showing:
  • Number of questions answered out of 80 total
  • Visual fill indicating completion percentage
  • Updates in real-time as you answer questions
You can navigate backward to review or change previous answers at any time. The progress bar tracks total questions answered, not your current position.

​

Review Your Scores

You’ll be taken to the results page showing your total score and subscale breakdowns.
If you haven’t enabled “Save Progress”, closing your browser will lose all responses. Consider exporting your results after completion.

​
Resuming a Saved Session

If you enabled progress saving:
  • Your responses are automatically saved after each answer
  • Returning to the site will resume where you left off
  • The application loads your saved progress from browser localStorage
  • You’ll see previously answered questions already filled in

​
Tips for Accurate Results

There’s no time limit. Consider each statement carefully before responding.
Select the option that best describes your experiences, even if it’s not a perfect fit.
Many questions ask about both current and past experiences. Consider your entire life when responding.
While you can save progress, completing within one or two sessions often provides more consistent responses.

​
Question Domains

The 80 questions are distributed across four assessment areas:
DomainQuestionsDescription
Social Relatedness39 questionsSocial interactions, empathy, understanding social cues
Circumscribed Interests14 questionsSpecial interests, focus, and routines

You won’t see domain labels during the questionnaire—they’re calculated in the results.
