If you or a family member has been referred for psychological testing, you may wonder what to expect. Or you may have heard about psychological testing and wonder if you or a family member should be tested. Psychological testing may sound intimidating, but it’s designed to help you.

In many ways, psychological testing and assessment are similar to medical tests. If a patient has physical symptoms, a primary care provider may order X-rays or blood tests to understand what’s causing those symptoms. The results of the tests will help inform develop a treatment plan.

Psychological evaluations serve the same purpose. Psychologists use tests and other assessment tools to measure and observe a client’s behavior to arrive at a diagnosis and guide treatment.

Psychologists administer tests and assessments for a wide variety of reasons. Children who are experiencing difficulty in school, for example, may undergo aptitude testing or tests for learning disabilities.

If a person is having problems at work or school, or in personal relationships, tests can help a psychologist understand whether he or she might have issues with anger management or interpersonal skills, or certain personality traits that contribute to the problem. Other tests evaluate whether clients are experiencing emotional disorders such as anxiety or depression.

The underlying cause of a person’s problems isn’t always clear. For example, if a child is having trouble in school, does he or she have a reading problem such as dyslexia? An attention problem such as attention-deficit hyperactivity disorder (ADHD)? Difficulty with impulse control? Psychological tests and assessments allow a psychologist to understand the nature of the problem, and to figure out the best way to go about addressing it.
