5 Pros of Psychological Tests, Plus 2 Cons

Though a psychological test may sound intimidating, the goal of these evaluations is to give insights into symptoms or behaviors to ultimately help improve your life. And knowing the pros and cons of psychological testing may help you better understand the role they can play in your wellbeing.

Much like common medical procedures like X-rays or blood tests are used to get to the bottom of physical issues, psychological evaluations can help reveal if a mental health or brain condition is the cause of your symptoms, per the American Psychological Association (APA). In non-medical settings, these tests may also be used to assess your personality, interests and skills for, say, a potential job.

Here are five advantages of psychological testing, plus two drawbacks.

Psychological testing may help you address mental health issues or sources of stress in your life. Here are the advantages of these evaluations.

If you suspect you have a mental illness or other mental health issues, psychological testing in a medical or mental health care setting may help you reach a diagnosis, according to the APA.

Evaluations like mood questionnaires or interviews with a therapist can provide a better understanding of your symptoms, behaviors, thoughts and emotions, all of which may help reveal underlying causes of your problems, per the Mayo Clinic.

The same goes for learning disabilities, developmental disorders and brain injury or illness, according to the APA. Medical or mental health professionals can investigate whether you might have a particular condition through various kinds of tests, including:

• Skill-based assessments like reading tests
• Tests to check your motor skills, like responding to images on a computer to measure reaction time, per the Cleveland Clinic
• Cognitive tasks to check your memory, thinking, language or judgment, like recalling information, per the U.S. National Library of Medicine

The pros of psychological testing don't stop at a diagnosis — pinpointing the root cause of your symptoms can also pave the way for getting the right treatment for your condition.

Psychological testing can also help reveal which areas to focus on during treatment, particularly when it comes to brain illness or injury, according to the Cleveland Clinic. For example, a neuropsychological test could help identify whether your treatment should address your interpersonal skills more than your physical abilities.

Psychological tests — particularly neuropsychological tests that examine your brain function, like those used after a brain injury or stroke — can help establish a baseline against which to measure your recovery progress, according to the Cleveland Clinic.

For example, you can compare your motor skill test results before, during and after treatment for a concussion to measure how your abilities have changed.

Psychological tests aren't only used in the case of diagnosable illness or injury. Other tests — like personality or psychiatric evaluations — can reveal interpersonal dynamics, sources of stress or environmental factors that may be causing you problems, per the APA.

Once you've identified those root causes, you can address your mental health with the help of a professional.

Another advantage of psychological testing is its ability to assess your professional skills, including interpersonal and cognitive abilities. These kinds of tests can help identify your interests, values, motivations and decision-making processes when it comes to work, per the Harvard T.H. Chan School of Public Health.

Your results can reveal what you value and the pros and cons of how you operate in professional settings, which can help you make informed decisions about your career (or other areas of your life, for that matter).

For instance, if you take a personality test that reveals you have a penchant for social engagement, it may help you decide to enter a career path or take on projects that allow you to work closely with people.

While there are many advantages to these evaluations, psychological tests aren't without their faults, including the following:

Psychological tests don't always account for other factors that may influence your behavior, like your culture, language, socioeconomic status, educational background or race, per September 2012 research in the ​Handbook of Psychology​.

For instance, giving an English reading test to a person who doesn't speak fluent English will not accurately measure their cognitive ability.

Similarly, test results often need to be interpreted by your medical provider. And in some cases, their understanding of the results may not reflect the full context of your life, symptoms, personality or emotions, according to the ​Handbook of Psychology​. This may get in the way of a proper diagnosis, treatment or understanding of your behavior.
