Do you think you may need an ADHD test? Individuals with ADHD can often forget to complete important tasks including homework. They might act without thinking and show signs of inattention. Another common symptom of ADHD is the inability to keep still. Individuals may be hyperactive.

An ADHD test can help determine if you or your child has ADHD. Because ADHD is a disability, people with ADHD are entitled to reasonable adjustments (accommodations or access arrangements) in examinations. Children with ADHD should have additional support at school on an ongoing basis. This support can be incorporated into their Educational and Health Care Plan (EHCP).

People at university with ADHD are entitled to Disabled Students Allowance for extra time and specialist support such as specialist tutors; and information technology applications that help students who have ADHD improve their study skills and ultimately examination results.

“An ADHD test is used to determine whether the symptoms are ADHD or other conditions such as learning disabilities, dyslexia, reactions to significant life events, psychological disorders such as depression, anxiety and bipolar disorder. These conditions may often coexist with ADHD. It is also essential to distinguish whether the individual has a behavioural disorder such as conduct disorder or oppositional defiant disorder. Finally, it is crucial to eliminate other medical conditions such as thyroid problems, neurological conditions, epilepsy and sleep disorders before a diagnosis of ADHD is made.”

ADHD Assessment

There are various ADHD tests. Your general medical practitioner, psychiatrist, or a paediatrician might carry out a medical diagnosis of ADHD. This would allow the individual to obtain medication to help control some of the adverse effects of ADHD. While some individuals find medication helpful, others find that medication does not help their ADHD.

Psychologists, on the other hand, carry out educational and occupational assessments of ADHD. These ADHD tests and assessments provide the individuals with an in-depth understanding of how ADHD impacts on their day-to-day functioning in education and employment.

ADHD may, for example, have an adverse effect on the ability of a candidate for a job to participate in an assessment centre fairly. Similarly, ADHD might adversely impact on an employee’s performance ratings and thus make it more difficult for them to stay in employment. Because ADHD is a disability, individuals with a diagnosis of ADHD will be protected under the Equality Act 2010. The employer, therefore, should make the necessary reasonable adjustments.

Once ADHD has been diagnosed through an ADHD assessment. An individual with ADHD may well be entitled to a free grant from Access to Work to help them stay in their job or run their own business. Individuals with ADHD may be particularly susceptible to unemployment.

Some individuals with ADHD may be more liable to have frequent car accidents; get in trouble with the law, and engage in substance abuse. Individuals with ADHD are often said to have unstable relationships and may be liable to suicide attempts.

ADHD Assessments by Expert Psychologists

Advanced assessments Ltd uses a comprehensive and robust ADHD assessment process. The assessment process involves a two-hour clinical interview with a Chartered Psychologist, completion of self-assessment forms and in most cases the completion of rating forms by another person that knows the person who is being assessed.

Observations of the individual concerned are carried out, and their behaviour is evaluated against the symptoms of ADHD that are set out in the Diagnostic and Statistical Manual (Fifth Edition). The expert psychologist might use the Diagnostic Interview for ADHD in Adults (DIVA), or the ADHD Child Evaluation Diagnostic Interview for Children.At the end of the process, a detailed report is produced. More information about our ADHD Assessments can be found by following this link.

Cognitive assessments are also carried out as part of the ADHD test, to examine issues such as how the individual with ADHD processes information. Our expert psychologists use the Wechsler Adult Intelligence Scale (Fourth UK Edition) for adults or the Wechsler Intelligence Scale for Children (Fifth UK edition). Because some individuals with ADHD also have problems with their working memory, we carry out assessments of working memory using the Wechsler Memory Scale (Fourth UK Edition) in the case of adults and the Test of Memory and Learning (Second Edition) for children.

Our ADHD tests also include an assessment of executive functioning; we use the Behaviour Rating Inventory of Executive Function (BREIF2). This test allows us to obtain information from the individual, and someone who knows the individual well to gather information about the executive function of the individual who is undergoing the ADHD assessment. We examine behavioural regulation, emotion regulation and cognitive regulation with this test.

Our expert psychologists also use the Adaptive Behaviour Assessment System (Third Edition) to obtain information from the individual about how they function, socially, cognitively, at work, and with respect to health and safety.

The ADHD assessment also uses one of two other gold standard ADHD tests. For children, we use the Conners 3. For Adults, we use the Connors Adult ADHD Rating Scales (CAARS). This allows us to obtain information from the individual, and other people that know the individual well about their symptoms. It also allows us to determine whether the individual has other conditions such as oppositional defiant disorder or conduct disorder.

ADHD Symptoms

"In examination settings, individuals with ADHD are very easily distracted. Many of the individuals that we assess failed to read the examination questions properly and answer a different question than the one which was asked by the examiner. Some individuals process information very slowly. People with ADHD are often said to be impulsive, disorganised and had difficulty setting priorities. They may exhibit poor time management skills."

It is essential to recognise that the symptoms in individuals with ADHD vary.
