Autism self-assessment for adults

Self-assessment means you are the source of every answer. Nobody observes you and nobody interviews your family. That makes it private and quick, and it also sets its limits: the result can only be as clear as your view of yourself on the day. This page explains how to get the most out of that, and exactly how the SpectrumFox score is put together.

How to answer a self-assessment well

The way you approach the statements shapes the result more than most people expect. A few principles help:

• Describe yourself as you are, not as you have trained yourself to appear. If you manage eye contact but it takes effort, the effort is the honest answer.
• Think about a typical month across settings: work, home, friends, errands.
• Answer for your life now, not for who you were at 12 or who you hope to be next year. Childhood comes up in a formal assessment instead.
• Use the middle option when a statement genuinely sits in the middle, not as a way to avoid deciding.
• Skip statements about settings you never encounter.

How the SpectrumFox self-assessment is scored

Scoring follows fixed rules that are the same for everyone and run on our servers, not in your browser:

1. Each answer becomes a number from 1 (strongly disagree) to 5 (strongly agree).
2. In each area, six statements are keyed toward the trait and two are reverse-keyed, so disagreeing with those two counts toward the area.
3. Each area gets an average from its answered statements, and needs at least six answers to be summarized.
4. The seven area averages are combined into one overall figure.
5. That figure is placed into a band: many, some or few traits commonly reported by autistic adults.

The band boundaries are design choices made by SpectrumFox, not cut-offs from research. We publish this openly because a self-assessment score is only useful when you know how it was made.

What your self-assessment score can and cannot show

The limits of any self-assessment questionnaire

Self-report runs on self-knowledge, and several things can blur it. Masking can make your answers describe a practiced version of yourself. Difficulty identifying feelings can make emotional statements hard to judge. Anxiety, low mood, ADHD and stress can raise agreement with some statements. None of this makes self-assessment useless. It means the result belongs alongside other evidence.

Other self-assessment questionnaires you may hear about

Names like the AQ, RAADS-R and CAT-Q come up often. Each is a published instrument with its own authors, scoring and research history, and each was designed for a particular purpose: the CAT-Q, for instance, measures camouflaging rather than autism. SpectrumFox is not adapted from any of them. Our test explainers describe how each one works and what studies say about its limits, without reproducing the items.

When a retake makes sense

Self-report answers move with circumstances. If you took the assessment during an unusually hard month, such as a move, a bereavement or a new baby, it can be worth taking it again once things settle. Retaking every day to see whether the band changes is less useful. Instead, compare which statements you answered differently and ask yourself why.

Adding an outside view

If you want to test your own answers, ask someone who knows you well how they see a few of the areas. A partner might notice how long you need after family events. A sibling might remember that you lined up toys or had one consuming interest at a time. You do not need to share your result. Their observations make useful notes for a professional assessment, which usually asks for exactly this kind of information.

From self-assessment to formal assessment

If your self-assessment and your own sense of things both point toward autistic traits that affect daily life, the next step is a conversation with a doctor or a psychologist who assesses adults. The optional Spectrum Profile report includes a one-page appointment summary built from your answers, which some people find easier than explaining everything from scratch.
