Autism Screeners

Quantitative Checklist for Autism in Toddlers (Q-CHAT)

The Q-CHAT is a screening tool designed to identify toddlers who may be at risk for autism spectrum disorder (ASD). It consists of a series of questions for parents or caregivers, focusing on behavioral signs and symptoms associated with autism in very young children. While it is not diagnostic, it provides an indication of whether a child might benefit from a more comprehensive assessment.

Childhood Autism Spectrum Test (CAST)

Formerly known as the Childhood Asperger Syndrome Test, the CAST is a questionnaire aimed at children aged 4-11 years old. It is used to identify children who may have ASD, specifically Asperger’s Syndrome or higher-functioning autism. Parents or primary caregivers complete the questionnaire, and a higher score suggests a higher likelihood of ASD.

Autism Spectrum Screening Questionnaire (ASSQ)

The ASSQ is a screening tool developed for identifying school-aged children who may have Asperger Syndrome or other high-functioning autism spectrum disorders. It is a 27-item checklist, designed to be completed by parents or teachers. It’s suitable for children aged 7-16 years.

Autism Spectrum Quotient (AQ)

The AQ is a self-assessment tool for adults (16+ years) to measure the extent to which an individual might have traits associated with the autistic spectrum. It comprises 50 questions and offers insights into social skill, communication, imagination, attention to detail, and tolerance to change.

ADHD Screeners

Adult ADHD Self-Report Scale (ASRSv1.1)

The ASRSv1.1 is a screening tool for Attention Deficit Hyperactivity Disorder (ADHD) in adults. Comprising a series of statements, respondents indicate how frequently each statement applies to their own behaviors. While not a diagnostic tool, it can indicate whether a person should seek further assessment for ADHD.

Anxiety Screeners

Hamilton Anxiety Rating Scale (HAM-A)

The HAM-A is a widely-used clinical assessment tool to evaluate the severity of anxiety symptoms. A clinician rates the patient on 14 different parameters, such as anxious mood, tension, fears, insomnia, and somatic complaints. The cumulative score provides a measure of the individual’s anxiety level.

Generalized Anxiety Disorder 7 Item Scale (GAD-7)

The GAD-7 is a self-report questionnaire designed to help individuals determine how much they have been affected by symptoms of generalized anxiety disorder. Consisting of 7 items, respondents indicate how often they have been bothered by specific symptoms during the past two weeks.

Depression Screeners

Beck Depression Inventory (BDI)

The BDI is a 21-question self-report inventory, one of the most widely used tools for measuring the severity of depression in individuals. Each question has a set of four possible answer choices, ranked in increasing severity. The BDI provides an indication of mood, pessimism, sense of failure, self-dissatisfaction, guilt, punishment, self-dislike, self-accusation, suicidal ideas, crying, irritability, social withdrawal, body image, work difficulties, insomnia, fatigability, loss of appetite, weight loss, bodily preoccupation, and loss of libido.

Patient Health Questionnaire-9 (PHQ-9)

The PHQ-9 is a self-report tool that consists of nine questions, used for screening, diagnosing, monitoring, and measuring the severity of depression. Based on the diagnostic criteria for major depressive disorder in the DSM-IV, the questionnaire is concise and is used in clinical practice as well as in research.

Considerations When Using Free Psychological Screener Tools

  1. Not a Definitive Diagnosis: It’s crucial to understand that screeners are not diagnostic tools. They provide initial insights that should be followed up with professional evaluations for a conclusive diagnosis.

  2. Variability: Different screeners might yield different results based on their design, focus, and scoring mechanisms. It’s beneficial to use screeners as part of a broader assessment strategy.

  3. Self-reporting Limitations: Many screeners rely on self-reporting, which can be subjective. Individuals might inadvertently underreport or overreport symptoms based on their current state of mind.


Free psychological screener tools play a pivotal role in the early identification of potential mental health and developmental challenges. By providing easy-to-access preliminary assessments, they bridge the gap between suspicion and professional consultation. As mental health continues to gain the attention it deserves, these tools will undoubtedly remain instrumental in guiding countless individuals toward understanding and support. Whether you’re an educator, parent, or individual seeking insights into your mental well-being, these screeners offer a helpful starting point on the path to clarity and potential intervention.
