Understanding Autism, ADHD, IQ & MBTI Tests

Millions of people search for free online psychological tests every year. Whether you're looking for an autism test, an ADHD test, a free IQ test, or a MBTI personality test, PsychSelfTest provides educational, instant, and completely private screening tools.


What Is an Autism Test?

An autism test — sometimes called an autism spectrum screening — is a structured questionnaire that explores traits associated with Autism Spectrum Condition (ASC) or Autism Spectrum Disorder (ASD). These traits include differences in social communication, sensory sensitivities, repetitive behaviors, and preference for routine. Our free online autism test is designed for adults, teenagers, and parents screening for their children aged 4 and above.

An online autism test cannot replace a formal clinical assessment. However, it can be a valuable first step in recognizing patterns and preparing for a conversation with a healthcare professional.

What Is an ADHD Test?

ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental condition affecting focus, impulse control, and activity levels. Our free ADHD test explores three presentations:

What Is an IQ Test?

An IQ test (Intelligence Quotient test) measures cognitive abilities including logical reasoning, pattern recognition, spatial awareness, and numerical thinking. Our free online IQ test provides an estimated cognitive score and a breakdown of your performance. This is an educational tool — official IQ scores require standardized testing by a licensed psychologist.

What Is an MBTI Test?

The MBTI test (Myers-Briggs Type Indicator) is one of the world's most widely used personality frameworks. It categorizes personality into 16 types based on four dimensions: Introversion vs. Extraversion, Sensing vs. Intuition, Thinking vs. Feeling, and Judging vs. Perceiving. Our free MBTI-inspired test helps you identify your personality type and understand your strengths.


Are These Tests Accurate?

Our tests are designed to be educational self-screening tools, not clinical diagnostic instruments. They are inspired by validated psychological frameworks and are useful for self-reflection and as conversation starters with professionals. For any clinical concerns, always consult a licensed psychologist, psychiatrist, or healthcare provider.
